[0071] Each of the actuators 21, 22, and 23 includes a housing. and a cap that is threadably connected to the canister. The pivot yoke 106 forming part of the housing is 18 via the active joint 92. The cap secures the pivot yoke 106 to the canister. 106. The pivot yoke 106 captures the annular shoulder of the pivot yoke 106 to secure the pivot yoke 106 in place.
[0072] In some versions, the pivot yoke 106 and the canister are spaced apart relative to one another. one for aligning each pivot yoke 106 with its respective canister in the target orientation; or a plurality of alignment features. Such alignment features may include coupling portions, keys / keyways, etc. During assembly, the pivot yoke 106 is first positioned relative to the can in a predetermined orientation.

The rotor and associated lead screw 15 are supported for rotation in a housing. The motor is configured to rotate relative to the housing upon selective energization of the motor. The lead screw 150 has precision pitch and lead to prevent backdriving. The lead screw has a locking angle (i.e., the lead screw is self-locking). As a result, Tool 2 A load placed at 0 will not easily backdrive the motor. The 150 threads are 8 to 36 class threads which produce a lead of 0.02 to 0.03 inches per turn. Has 3 threads. Other thread types / sizes may be used.
[0074] Each actuator 21, 22, 23 may be controlled by a separate motor controller. The motor controller individually controls each actuator 21, 22, 23 to a given target position. Each of the actuators 21, 22, 23 may be separately wired for orientation. In some examples, the motor controller is a proportional-integral-derivative (PID) controller. In some examples, the motor controller generates a cascade of related position, velocity and torque (current). Additionally and / or alternatively, the motor controller may include a In another example, the position control loop may include only a torque (current) control loop. Each of these control stages may be fed directly into the torque (current) control loop. controller, may be implemented as a state space controller, and / or alternatively or additionally Using control techniques (e.g., velocity feedforward, torque feedforward, etc.) In some cases, the torque (current) control loop is controlled by field-oriented control and space vector The control loop stages are distributed among the various components of the system. In some examples, the position loop and velocity loop can be controlled by the instrument control. The torque control loop is implemented in the control housing 29 of the instrument 14. Implemented directly on the control board 31 as part of the instrument through connection to the console 33 This reduces the impact of data communication latency from the controller 14 because the current control loop This is because it does not require any data feedback via source 33. The loop and speed control loop are insensitive to communication latency and are In some examples, the motor controller may be implemented in an implement controller. 28 or may form part of the appliance control device 28 For ease of illustration, the motor controller is referred to herein as part of the implement controller 28. It is explained as follows.
[0075] The power supply provides a 32VDC power signal to the motor via, for example, console 33. A 2VDC signal is applied to the motor through the implement controller 28. The implement controller 28 A power signal is selectively provided to each motor to selectively operate the motor. Selective actuation of the motors positions the tool 20. The motor may be of any type, such as a brushless DC servo motor, a permanent magnet synchronous motor, or other The power supply provides energy to the internal components of the tool controller 28. It also provides power to the instrument controller 28 to power the actuator. The actuator motor may be a three-phase brushless motor. The actuator motor may be a DC motor. The actuator motor may be a permanent magnet synchronous motor. The motor may be configured with a sinusoidal back EMF and is designed to achieve limited mechanical cogging. This allows for smooth, specific motion and limits torque ripple. However, other motor types are possible. Power supplies include, for example, 12VDC, 24VDC It is recognized that other types of power signals, such as 40VDC, may be provided. The device should use electronic switches, e.g., MOSFETs or GaN FETs. Then, the voltage signal is PWMed to produce a high frequency, e.g., typically at least 16 kHz, Turns a three-phase motor on and off at rates up to 256kHz.
[0076] In one possible implementation, one or more sensors S (see also FIG. 7) remeasure the signal. The tool controller 28 then transmits the associated actuator 2 Determine the current position and / or angle (i.e., measured position) of 1, 22, 23 The levels of these signals vary with respect to the rotational position of the associated rotor. In one implementation, the sensor S is localized within a given rotation at high resolution. These sensors S may resolve the rotational position of the rotor or lead screw 15. The analyzer is based on the detected magnetic field from other magnets (e.g., two-pole magnets) placed at 0. It may be a Hall effect sensor that outputs a log and / or digital signal. A low voltage signal, e.g., 5VDC, is required to energize the Hall effect sensor. may be provided by a motor controller associated with the associated motor. Two Hall effect sensors are located in the housing to detect the joint position. are spaced 90 degrees apart from each other around the rotor to allow for The controller 28 is able to determine the position and count incremental rotations of the rotor. In this version, the Hall effect sensor output digital signal represents an incremental count. Various types of motor and sensor arrangements are possible. In the present invention, the motor is a brushless DC servo motor with two or more internal Hall effect sensors. The sensors are spaced 90 degrees, 120 degrees, or any other suitable distance from each other around the rotor. The sensor S may also include an absolute or incremental encoder. This can be used to detect the rotor's rotational position and count rotor revolutions. Other types of encoders may be used as one or more sensors. The sensor may be attached to the housing, nut, screw, etc. of each actuator when it is adjusted. Any suitable actuator and surrounding components for determining the position of In yet another configuration, sensorless motor control is utilized. In such an implementation, the position of each rotor may be determined by the motor back-EMF and / or may be determined by measuring the inductance. One suitable example is Such may be found in U.S. Pat. No. 7,422,582, which is incorporated herein in its entirety. be.
[0077] In some examples, sensors and / or encoders are used for joint position control. and / or the handheld portion when used in conjunction with the kinematic model of the instrument 14 Measure the position feedback to determine the position of the tool support 18 relative to the tool support 16. In some instances, sensors and / or encoders rely on multi-turn measurements. This accumulates with each rotation and determines the absolute position of the actuators 21, 22, 23 along the axis. is used to determine the position of the lead screw with a known pitch (i.e., turns per inch) Additionally or alternatively, the sensor and / or encoder may be , to determine the "rotor electrical angle" for use in electronic commutation of the motor. For example, sensors and / or encoders may be used to determine the rotor position and To apply the appropriate energy supply signal to achieve optimal (efficient) torque generation In this example, a sensor and / or encoder may be used to measure the electrical Using a single turn or subturn (within one electrical revolution) that rotates over The number of electrical revolutions is determined by the number of mechanical revolutions, which is determined by the number of magnetic poles (e.g., number of pole pairs) of the motor. However, it is conceivable that a sensorless method could be implemented. .
[0078] In some examples, the output signal from the Hall effect sensor is sent to the implement controller 28. The appliance controller 28 monitors the received signals for changes in their levels. Based on these signals, the tool controller 28 determines the joint positions. The position may be considered to be the degree of rotation of the rotor from an initial or home position. It can rotate 360° multiple times. Therefore, the joint position can be adjusted by A scalar value called count is the distance from the home position of the joint. The rotor rotates clockwise and counterclockwise. Multiple signals (analog or Whenever the signal level of the instrument controller 28 (either digital or digital) undergoes a defined change of state, The count increases or decreases, indicating a change in joint position. For every 0° of rotation, the instrument controller 28 increments the count by a fixed number of counts. In some examples, the count is increased or decreased by 1 for every 360° of rotor rotation. In some cases, the joint position can be increased or decreased by 0.00 to 3000. When an incremental encoder is used to monitor the rotation of the rotor over 360°, There are 1024 positions (counts) per rotation. There are counters associated with the actuators 21, 22, and 23. The counters are incremented. The count value can be positive, zero, or In some versions, the count value is the rotor increment. Therefore, the rotors of the actuators 21, 22, and 23 first The sensor may be moved to a known position, called the "home position" (discussed further below), and then The count value is used to define the current position of the rotor.
[0079] As previously described, the carrier has a female thread for threadably receiving the lead screw 150. The actuators 21, 22, and 23 have corresponding through holes with threads. The corresponding effective length is adjusted, thereby reducing the counter measured by the tool controller 28. Each lead screw 150 rotates relative to a corresponding one of the carriers to change the Each housing and corresponding carrier can rotate. Relative movement in at least one degree of freedom is constrained to rotate relative to the carrier. More specifically, they rotate about the associated active axes AA1, AA2, and AA3. The pivot yoke 106 is not movable (i.e., the pivot yoke 106 is the first active (The configuration of the Point 92 limits such rotational movement) and the associated active shaft. Carriers that cannot rotate around lines AA1, AA2, and AA3 (i.e., carriers A is achieved by the configuration of the second active joint 108 and the third active joint 124. The lead screw 150 is rotated relative to the carrier by the rotational movement of the lead screw 150 being restricted. It is possible.
[0080] A stop 152, such as a threaded fastener and shoulder, formed on the lead screw 150 , are fixed to the lead screws 150. The stoppers 152 are used to stop the movement of each lead screw 150. It is sized to abut the carrier 116 at its end.
[0081] As previously explained, the actuators 21, 22, and 23 are connected to the handheld portion 16. The effective length is actively adjustable to allow movement of the tool support 18. An example of an effective length is shown by "EL" on the third actuator 23. The effective length EL is measured from the pivot axis PA to the center of the associated first active joint 92. Each actuator 21, 22, 23 is adjusted so that the lead screw 150 whether it is screwed into or out of the associated carrier Shifting the center of the associated carrier to the associated first active joint 92 The effective length EL is changed by changing the distance to the center of the actuator 2. The actuators 1, 22, and 23 are adjustable between the minimum and maximum effective lengths EL. The effective length EL of the tools 21, 22, and 23 is the tool support 18 relative to the handheld portion 16. The tool along the active axes AA1, AA2, AA3 changes to cause various movements of the The distance between the support 18 and the handheld portion 16 may be expressed in any suitable format. It can be measured.
[0082] The constraint assembly 24 constrains the movement provided by the actuators 21, 22, and 23.

The second pivot pin 170 is adapted to receive the first pivot pin 158. The first pivot pin 158 and the joint block 1 60 and the second pivot pin 170 form the cross of the U-joint. The pivot pin 158 and the second pivot pin 170 define an intersecting pivot axis PA. As a result, the passive link mechanism 26 has two freedoms relative to the tool support body 80. A passive link includes a ball with a slot that receives a pin. Other types of passive linkage joints are also possible, such as passive linkage spherical joints. .

The boundary 184 may be one-dimensional (1D), two-dimensional (2D), or three-dimensional (3D), and may be a point, a line, or a , axes, orbits, planes (infinite planes or planar segments bounded by anatomical structures or may include other boundaries), volumes or other shapes, including complex geometric shapes. The virtual boundary 184 can be a set of points, point clouds, voxels, triangle meshes, or other 2D or 3D models. It may be expressed by a combination thereof, etc. No. 8,898,043 are incorporated by reference, and any of their features may be incorporated herein by reference. Either may be used to facilitate the planning or execution of a surgical procedure.
[0092] The virtual boundary 184 may be used in a variety of ways. For example, the control system 60 may Some movement of the tool 20 may be controlled to stay within the boundary; may control certain movements of the rule 20; stay on boundaries (e.g., points, trajectories and / or Some movement of the tool 20 may be controlled so that the tool 20 remains on the plane; A certain movement of the tool 20 is either (attractive boundary) or repelled by the boundary (repulsive boundary). and / or the relationship of the instrument 14 to the boundary (e.g., spatial, velocity, etc.) ) may control certain operations / functions of the instrument 14 based on the boundary 184. Other uses of the boundary 184 are also contemplated. can be obtained.
[0093] In some instances, one of the virtual boundaries 184 may be located at the desired cutoff point, as shown in FIG. The control system 60 ultimately controls the tool 20 in some versions. The virtual boundary that controls the positioning of the tool 20 functions to keep the tool 20 on the desired cutting plane. The field 184 is then sorbed to stay within the boundaries and on the desired cutting plane as shown in FIG. A volume boundary, such as one with a thickness slightly greater than the blade thickness, is used to constrain the blade. Therefore, the desired cutting plane may be a virtual planar boundary, a virtual volume boundary, or Other types of virtual boundaries may be used. The virtual boundary 184 may be referred to as a 3D bone model or an anatomical model AM. (Their registration allows them to be virtually superimposed on the actual femur F.) (See Figure 2, which shows the anatomical model AM). In other words, the points relative to the virtual boundary 184 , lines, axes, trajectories, planes, volumes, etc. are fixed relative to the coordinate system of the anatomical model AM. The system may be defined to allow for the identification of (e.g., registered) relevant anatomical structures. Tracking of the anatomical model AM (via tracking) also enables tracking of the virtual boundary 184.
[0094] The anatomical model AM is configured such that the virtual boundary 184 is connected to the anatomical model AM and the associated coordinate system. The virtual boundary 184 is registered in the first patient tracker 54 so as to be associated with the first patient tracker 54. For implants, e.g., based on the size, shape, volume, etc. of the implant and / or may be patient specific, for example, defined based on the patient's anatomy. The virtual boundary 184 may be a boundary generated pre-operatively, intra-operatively, or a combination thereof. In other words, the virtual boundary 184 is configured before the surgical procedure begins, during the surgical procedure (during tissue removal), The virtual boundary 184 may be defined as a Control systems 60, which generate data, receive data from other sources / systems, etc. The virtual boundary 184 may be provided in many ways, such as by searching and / or updating may be stored in memory for
[0095] Some procedures, such as preparing the femur F to receive the knee prosthesis IM (see Figure 1), In this case, the virtual boundary 184 includes a plurality of flat boundaries, which define the prosthetic knee joint. Can be used to draw multiple cutting planes (e.g., five cutting planes) for section IM. These multiple virtual boundaries 184 are related to the 3D model of the distal end of the femur F. are calculated one at a time by the control system 60 to constrain the cut to one plane at a time. can be activated.
[0096] The instrument controller 28 and / or navigation controller 36 may be configured to In one example, the tool 20 remains in a desired state. To determine the target positions for the actuators 21, 22, and 23, the TCP coordinates are The state of the reference frame (e.g., the pose of the saw blade) is measured with respect to the virtual boundary 184. In some cases, the control system 60 may be configured to control the physical handpiece in the presence of a physical boundary / barrier. The device controls / positions the instrument 14 in a manner that emulates the manner in which the device responds.
[0097] Referring again to FIG. 7, two additional software programs or modules are: It runs on the instrument controller 28 and / or the navigation controller 36. The software module performs behavior control 186. The behavior control 186 is Data indicating the next commanded / desired position and / or orientation (e.g., desired pose) In some cases, only the desired position of the TCP is calculated from the behavioral control 186. In some cases, the commanded pose of the tool 20 is output. The output from the field generator 182 (e.g., a virtual boundary 1 in one or more of the coordinate systems) 84) is the next command of the actuators 21, 22, 23. to the behavior control 186 to determine the determined position and / or orientation for the tool 20 The behavior control 186 uses the following to determine the commanded pose: This input may be processed along with one or more other inputs, as further described below.
[0098] The tool controller 28 controls each actuator to adjust the tool 20 towards the desired pose. One or more actuators are controlled by sending command signals to the actuators 21, 22, and 23. The tool controller 28 may control the actuators 21, 22, and 23. , 23 knows the overall length to which the tool support 18 may be adjusted relative to the handheld portion 16. In some examples, the tool controller 28 may Knowing the total length that can be adjusted, to move the measured distance from position to position Command signals may be sent to the actuators 21, 22, 23. The measured position may be calculated based on a known Position or current position and actuator limits of actuators 21, 22, 23 The positions to which the actuators 21, 22, and 23 move may be the distance between the actuators 21, 22, and 23. The measured distance from the positive and negative limits of actuator travel (i.e., the lead screw The instrument controller 28 may measure the distance between the two ends of the instrument, as described below. Command the actuators 21, 22, 23 to and from the measured positions. stomach.
[0099] The tool controller 28 controls the actuators 21, 22, 23 to move the tool 20 from the first position. Each actuator 21, 22 moves to a commanded position to place the actuator in a desired pose. , 23. In some examples, the commanded position may be may be determined by the implement controller 28 in conjunction with the application system 32, thereby Virtual objects such as the handheld portion 16, patient trackers PT, 54, 56, and desired cutting planes are displayed. determining the position of the tool 20 and tool support 18 relative to the object, or a combination thereof; and adjust a distance or commanded position to place the tool 20 in the desired pose. The tool controller sends signals to the actuators 21, 22, and 23 to Command the actuators 21, 22, 23 to a predetermined position to reach the desired adjustment of 0. The tool controller 28 may use calculations to adjust the tool 20 towards the desired pose. The actuators 21, 22, and 23 may be controlled to move linearly a specified distance. In other instances, such as when absolute encoders are used, the implement controller may: Tool support 1 for handheld part determined by absolute encoder 8, each actuator 21, 22, 23 is placed in a commanded position based on the known position of the A signal may be sent to the actuators 21, 22, 23 to
[0100] The tool controller 28 controls the actuators 21, 22, and 23 relative to the handheld portion 16. In some instances, the overall length to which the tool support 18 can be adjusted may be known. The device 28 knows the total length that the actuators 21, 22, 23 can adjust. , measured (e.g., by commanding a desired amount of linear movement via a commanded rotation) A command signal is sent to the actuators 21, 22, and 23 to move the specified distance for each position. The measured position may be a known position or may be transmitted to the actuator 21,2. Actuator 2 may be the distance between the current position of 2, 23 and the actuator limit. Each position that 1, 22, and 23 move to is determined by the positive and negative limits of the actuator travel. The distance measured between the two ends of the lead screw may be the distance between the two ends of the lead screw. The controller 28 controls the actuators 21, 22 to and from positions as described below. , 23. The implement controller may command the actuators to reach the desired adjustment of the tool 20. The implement controller 28 may command the tools 21, 22, 23 to a predetermined position. 0 to move the calculated distance linearly to adjust it towards the desired pose. Actuators 21, 22, and 23 may be controlled. An absolute encoder is used. In other instances, such as when the implement controller is The actuators 21, 22, and 23 between the determined actuator travel limits To place each actuator 21, 22, 23 at a commanded position based on the known position, Alternatively, in one example, No. 2017 / 0156799, which is incorporated herein by reference. As described in the previous section, the interface is used in conjunction with the homing procedure that occurs during system setup. A homing procedure may be used, and the actuator Place the actuators 21, 22, 23 and the joints in a centered position, then Determine the absolute offset of the incremental encoder. By determining the offset, the incremental encoder can generate absolute forward motion. It may function as a meter encoder.
[0101] In some instances, if a homing position is used, the homing process may Establish the initial rotor position (zero position) of the actuators 21, 22, and 23. The home position is Effectively provides the maximum possible movement in each direction along active axes AA1, AA2, and AA3 In some examples, the home position is generally the position of the rotor 148 at which the stopper The home point HP of the lead screw 150, which is located midway between the associated The actuator is positioned so that it is centrally located on the carrier 116 that is being used (the actuator in the home position). (See Figure 12, which shows two of the encoders 22 and 23.) Other modes (explained further below) may also be used even if no homing procedure is used, such as Before or after executing the approach mode, the actuators 21, 22, and 23 are held This may include setting the home point HP. 21, 22, 23. Actuator 2 is placed at the home position between the minimum and maximum values of the effective length EL. 1, 22, and 23.
[0102] When in the home position, actuator 2 is used to maintain tool 20 in a desired pose. The amount of adjustability of the devices 14, 22, and 23 is maximized. Various levels of adjustment are possible depending on the configuration. In some instances, all actuators When the sensors 21, 22, and 23 are in their home positions, there is zero change in roll orientation and z-axis Assuming no translation, the tool 20 is adjusted with a pitch orientation of approximately ±18° relative to the home position. In some examples, all of the actuators 21, 22, and 23 may be in the home position. , assuming zero change in pitch orientation and no z-axis translation, the tool 20 , may be adjusted with a roll orientation of about ±33° relative to the home position. When all the actuators 21, 22, 23 are in the home position, the pitch orientation and roll Assuming zero change in tool orientation, the tool 20 will rotate approximately ±0.37 degrees relative to the home position. The tool 20 may, of course, be adjusted in z-axis translation by 1 / 2 inch. Combinations thereof may be adjusted in pitch, roll and z-axis translation.
[0103] In some examples, one or more of the actuators 21, 22, 23 When these limits are reached, the implement controller 28 determines whether the actuator will move the tool 20 to the desired position. 1 to bring the handheld portion 1 back into the range where the tool 20 can be adjusted toward the 6 may require adjustments to be made. In such cases, How to return the handheld unit to the control panel 20 and the actuators 21, 22, and 23 To show the user how to move 16 minutes, a simulated commanded position is displayed. The simulated commanded positions may be used to , 23 to adjust the tool 20 toward the desired pose. Navigation information from the navigation system 32 to which the road portion 16 must be moved. The location may be determined by the tool controller 28 in conjunction with the location data. The simulated commanded positions are then handled to place the tool 20 in the desired pose. Signaling to the user that handheld portion 16 needs to be moved in a particular manner. In some instances, the actuators work in conjunction with one or more displays 38 to The handheld portion 16 is adjusted as if the eters 21, 22, and 23 were adjusting the tool 20. a guidance array 500 for transmitting signals to the user to move in the same manner; However, by manipulating the handheld portion 16 while the actuator remains in place, Thus, it relies on the user to correct the pose of the tool 20.
[0104] The second software module performs motion control 188. One state of motion control 188 is The first mode is the control of the instrument 14. The movement control 188 executes the next commanded position from the behavior control 186. Based on this data, the motion control 188 (e.g., For example, via inverse kinematics, the next rotor of the rotor 148 of each actuator 21, 22, 23 The controller 14 determines the position of the robot, so that the robot can control the robot's behavior, for example, in a commanded pose. The tool 20 can be positioned as commanded by the control 186. For example, motion control 188 may control the instrument 1 to execute a commanded pose, which may be defined in Cartesian space. 4 actuator position (e.g., rotor position), so that the tool controller 28 , the motors 142 can be commanded accordingly, and the motors 142 can be commanded accordingly to the commanded pose of the tool 20. The actuators 21, 22 of the instrument 14 are moved to a commanded position, such as a commanded rotor position. In one version, the motion control 188 controls the rotation of each motor 142. The motor position is adjusted so that the motor 142 commands the associated actuators 21, 22, 23. To ensure that the rotor position is driven as precisely as possible, each motor 142 The torque is continuously adjusted.
[0105] In some versions, the tool controller 28 controls each of the actuators 21, 22, 2 3, determine the difference between the measured position and the commanded position of the rotor 148. The tool controller 28 outputs a target current (proportional to the torque of the rotor) to the actuator. The voltage is changed to adjust the current in the electrode from an initial current to a target current. The actuators 21, 22, and 23 are moved to move the tool 20 from the measured pose. Move to the commanded pose. This is the result of converting the commanded pose into joint positions. In one example, the measured position of each rotor 148 may be measured using a signal such as an encoder. For example, it may be derived from the sensor S described above.
[0106] The boundary generator 182, the behavior control 186, and the movement control 188 are software programs Alternatively, each may be a subset of the other in any combination thereof. The software may be software programs that operate individually and / or independently. The term "software program" refers to the software that implements the various capabilities of the described technical solution. As used herein to describe computer-executable instructions configured to For simplicity, the term "software program" is used to refer to at least Any one of the field generator 182, behavior control 186 and / or movement control 188 The software program is intended to include one or more of the following: 8, navigation control device 36, or any combination thereof. may be implemented in any suitable manner by control system 60.
[0107] A clinical application 190 may be provided to handle user interactions. The floor application 190 handles many aspects of user interaction, including pre-operative planning, External assessment including implant placement, registration, bone preparation visualization and postoperative evaluation of implant fit Coordinates clinical workflow. Clinical application 190 outputs to display 38 The clinical application 190 is configured to run on its own separate processor. or may operate in the appliance controller 28 and / or the navigation controller 3 6. In one example, the clinical application 190 may operate in parallel with the After the runt placement is set by the user, it interfaces with the boundary generator 182. The virtual boundary 184 returned by the boundary generator 182 is then passed to the instrument control device for execution. The data is transmitted to device 28.
[0108] The initial position of the base coordinate system BCS is determined by the actuators 21, 22, and 23 being at their home positions or is the coordinate system of the tool support coordinate system TCS and the base coordinate system BCS when the tool is in a predetermined position. The actuators 21, 22 can be determined based on the known geometric relationship between them. This relationship changes as the coordinates are adjusted (e.g., establishing a dynamic transformation between these coordinate systems). Based on the motion of the robotic system 10, the associated changes can be determined. Alternatively or additionally, the position of the base coordinate system BCS relative to the tool support coordinate system TCS A separate tracker is mounted and fixed with respect to the base coordinate system BCS to track the object directly. Therefore, the robot system 10 can The position of the controller 20 and its relationship to the pose of the handheld portion 16 are known. The tool 20 is moved by the user and its pose is recorded using the tool tracker 52. Once tracked, the robotic system 10 calculates the coordinate system of the handheld portion 16 and its base coordinate system. The pose of the BCS is also tracked. In some instances, the tool support is determined as a result of a previous calibration process. The position of the tool 20 relative to the body 18 is assumed to be known.
[0109] In some versions, the home position is a separate device fixed to the handheld portion 16. tracker to the tool support 18 in a common coordinate system (e.g. the handheld portion 16 (e.g., relative to the base coordinate system TCS) The handheld part 16 and the tool are then connected to the robot. This spatial relationship with the handheld support 18 allows the pointer 57 and by registration using known calibration divots or other navigation methods. Then, the current load of each of the actuators 21, 22, and 23 can be determined. The position of the current sensor can be derived from this spatial relationship based on the movement of the instrument 14. The rotor position is known and the encoder (and corresponding encoder signal) is used to measure the current The implement controller 28 then measures the change in rotor position from the home position. The home position is the position where the actuators 21, 22, and 23 are operated. It can be stored in the memory of the controller 28.
[0110] Essentially, the tool controller 28 uses a A track coupled to the tool support 18 and handheld portion 16 of the instrument 14 is provided. using tracking data acquired by the navigation system 32 from the vehicle 52, Therefore, the incremental encoder then acts as an absolute encoder. It is possible.
[0111] From the console 33 or another component of the tool controller 28, e.g., the motor control Instruction data packets are sent to the device. The data packets are used to determine the target position (or actuator position) for the rotor 148 of the motor 142. where each target position is a target cumulative position for the associated rotor 148. It can be a positive or negative number representing the count. Other components generate these instruction data packets and It sends one packet every 4 milliseconds to each motor controller. Therefore, each motor controller receives instruction data at least once every 0.125 milliseconds. Receive the data packet.
[0112] In use, the robotic system 10 determines the pose (current pose) of the tool 20 using the navigation system 32 by means of a tracker 52 disposed on the tool support 18. The instrument control device 28 may determine the current position of each of the actuators 21, 22, 23 based on output encoder signals from one or more encoders disposed on each of the actuators 21, 22, 23. Upon receiving the current position of each of the actuators 21, 22, 23, the instrument control device 28 may calculate the current pose of the handheld portion 16 (e.g., using a TCP coordinate system that uses forward kinematics to convert from actuator positions to poses, such as the current pose of the base coordinate system BCS with respect to a desired coordinate system (TCP with respect to BCS)). If the instrument control device 28 has the current relative poses of the tool support 18 and the handheld portion 16 in a desired coordinate system, the instrument control device 28 may then determine the commanded pose of the tool 20 based on the current pose of the tool 20 determined by the navigation system 32, the current pose of the handheld portion 16 calculated based on the current positions of each of the actuators 21, 22, 23, and the position and / or orientation of a planned virtual object that is the subject as a desired cutting plane. The instrument calculates the pose (commanded pose) of the TCP with respect to the BCS that results in a TCP aligned with the desired or planned virtual object in a plane. The instrument control device 28 may send command instructions to the actuators 21, 22, 23 to move to the commanded position, thereby changing the poses of the tool support 18 and the tool 20. In one example, the commanded pose of the tool 20 is further based on a target cutting plane and thus, the instrument control device 28 may adjust the commanded pose of the tool 20 based on the target cutting plane. The instrument control device 28 may send command instructions to the actuators 21, 22, 23 to move to the commanded position, thereby changing the poses of the tool support 18 and the tool 20. In one example, the commanded pose of the tool 20 is further based on a target cutting plane and thus, the instrument control device 28 may adjust the commanded pose of the tool 20 based on the target cutting plane. The instrument calculates the pose (commanded pose) of the TCP with respect to the BCS that results in a TCP aligned with the desired or planned virtual object in a plane. The instrument control device 28 may send command instructions to the actuators 21, 22, 23 to move to the commanded position, thereby changing the poses of the tool support 18 and the tool 20. In one example, the commanded pose of the tool 20 is further based on a target cutting plane and thus, the instrument control device 28 may adjust the commanded pose of the tool 20 based on the target cutting plane. The tool controller 28 controls the tool support 16 to determine the current pose of the handheld portion 16. Calculate the current pose of the robot 18 and the current positions of the actuators 21, 22, and 23. The current pose of the support 18, the current positions of the actuators 21, 22, and 23, and the hand Knowing the current pose of the heald portion 16, the implement controller 28 determines the desired plane based on Actuators 21, 22, and 23 for adjusting the tool support 18 and the tool 20 The control unit can send a command signal to the hand momentarily (for one repetition). Assuming the hemispheric pose (BCS) is static relative to the patient anatomy, By updating the corresponding pose every time, the actual BCS The movement is adjusted.
[0113] An exemplary control is described with respect to various transformations with reference to FIG. The tool 20 is tracked by the tracker 52 at Z (LCLZ-TT) and the registration data is 20, such as a saw, to perform a conversion (TT- Similarly, patients in LCLZ are It is tracked using a tracker PT (shown as 54) (LCLZ-PT). The Patient Tracker-TP exchange (PT-TP) uses registration data and plan information to The planned virtual object 184 (TP) is determined between the two. The conversion between CS and TCP (BCS-TCP) is performed by calculating the current position of each actuator (see above). The conversion between BCS and TCP is done by re-handling the various coordinate systems. This is used to associate the commanded pose with the handheld portion 16. Conceptually, the commanded pause can be determined from the BCS to the TC. P, so that TCP can The object 184 (target plane TP) is aligned with the object 184.
[0114] The phrase "TCP of the fixture" is used interchangeably with the phrase "saw blade location." Therefore, the TCP of the instrument / tool is used. In all instances, the position of the saw blade may be substituted, or vice versa. Of course, the "saw blade" position can alternatively be replaced by a drill, burr, guide tube, etc. The tool may be a location for any suitable configuration, such as a screwdriver, tap, pin, etc.
[0115] Throughout this description, unless otherwise specified, all examples of poses are the poses commanded. These poses may be the current pose, a past pose, or a past commanded pose. The pauses may differ from each other depending on the frequency of the control, but the positions between these pauses The difference in position and / or orientation may be minimal in each control iteration.
[0116] It should be understood that the combination of an object's position and orientation is called the object's pose. Throughout this disclosure, the term pause achieves a suitable alternative to the concepts described herein. may be replaced by position and / or orientation, or vice versa, to In other words, any use of the term pose can be interchanged with position, Any use of the term position may be replaced with pose.
[0117] 〔operation〕 During operation, the robotic system 10 is first powered up and configured to A software application is started to operate the trackers 52, 54, and 56. , PT is initialized and the trackers 52, 54, 56 are synchronized with the instrument 14 and the target anatomical structure ( For example, the trackers 54, 56 are placed on the femur F and tibia T. Once attached, the anatomy and / or associated images / models are aligned with known registered The location is registered in the trackers 54, 56 using a registration technique. This may require touching an anatomical surface or landmark. For example, this can occur when the user presses the select button on the pointer 57 or navigates While pressing the foot switch of the motion system 32, place multiple points on the surface of the anatomy. This may require palpation of the anatomy. Surface points in the navigation system 32 for matching with intraoperative images / models Pre-operative and / or intra-operative images / models of the anatomy are The portion of the anatomy to be tracked is loaded into the navigation system 32. By extension, this allows the robotic system 10 to A graphical representation of the actual position and orientation of anatomical structures as they are moved This allows it to be displayed on the display 38.
[0118] During the calibration / registration procedure, the orientation and position of the tracker 52 is determined by the calibration divot CD or tool support by referencing fixed, known positions of other reference points. 18. In some examples, one or more trackers 52 , may be located on the tool support 18, the handheld portion 16, or both, thereby The position of the tool support 18 and / or handheld portion 16 is determined by the navigation system. In the example where the tracker 52 is integrated into the instrument 14, Since the relative position of the tracker 52 with respect to the tool support 18 is known, such calibration is It is unnecessary.

The software that creates / obtains the initial definition of the virtual object. If so, have the ability and options to adjust the nature / placement of virtual objects. stomach.
[0120] In one exemplary configuration, the control system 60 controls the target site and / or anatomical Various regions are defined at predetermined distances and / or locations from the structure. It is defined in a coordinate system relative to anatomy and / or a virtual boundary 184. In some cases, these regions may be spherical regions around the target site and / or anatomical structure. or other geometric primitives. and others described below) comprise the instrument 14, tool support 18, handheld portion 16, , tool 20, target site / anatomy, or a combination thereof. The handheld portion 16, tool support 18, tool 20, target site / anatomy, or The area defined by the combination of these is connected to a specific virtual boundary / virtual cutting guide feature. When the control system 60 approaches, the control system 60 may control the instrument 14 .
[0121] In particular, the instrument controller 28 generates a set of target rotor positions and controls the motor 142. The rotor 148 is configured to set a target rotor position to maintain the tool 20 at a desired pose. In other words, the user must rotate the tool away from the desired pose. When the handheld portion 16 is moved in the manner of moving the wheel 20, this The movement is detected by the navigation system 32. In response to this movement, the implement controller 28 Based on data from the navigation system 32, the tool 20 moves away from the desired pose. Determine how far the tool has moved and adjust as needed to return the tool 20 to the desired pose. Such movement is compensated for by driving the actuators 21, 22, and 23 with the To continuously counter such deviations in substantially real time, the implement controller 28 is Since the frame rate is high, this deviation from the desired pose is It should be recognized that deviations will usually be small.
[0122] The target rotor position is determined by the actuation of the actuators 21, 22, and 23 and the resulting movement For example, the desired pose is determined based on the relationship between the handheld If z-axis translation is required for the tool portion 16, the tool 20 must be moved in the z-axis. degrees and the amount of rotation of each rotor 148 (e.g., how many counts such z-axis movement There is a linear relationship between the tool 20 and the first and second In combination with one or both of the first and second actuators 21, 22, a third actuator There is also a relationship between the degree to which the pitch orientation changes in response to actuation of actuator 23. Later, with or without the operation of the third actuator 23 The tool 20 is driven by one or both of the first and second actuators 21 and 22. There exists a relationship between the degree to which the roll direction changes in response to the actuation of either the Based on this, the instrument controller 28 may determine the required position to maintain the desired pose of the tool 20. The instrument controller 28 determines a target rotor position for each rotor 148. The motor 142 is actuated based on the target rotor position. For example, the console 33 may , and each motor controller may send a packet to the motor controllers containing the target rotor position of , appropriate energy supply signals may be applied to the associated motors 142.

By maintaining the tool 20 in the home position or other predetermined location, the user Adjusting the tool 20 to better align the instrument pose with the desired plane and target. However, when the tool is in the desired pose, the visual The dynamic guidance moves the actuators 21, 22, 23 to a home position or other predetermined position. The handheld device is designed to provide sufficient adjustability for the instrument 14 by keeping it close to the handheld device. It is intended to guide the user as to how to move the hand portion 16. For example, the user may move all actuators while maintaining the tool 20 in a desired pose. The handheld portion 16 is used to move the controllers 21, 22, and 23 closer to the home position. In other words, the actuator may need to be moved upward in the z-axis direction. The guides 21, 22, 23 may be nearly fully extended. The direction indicated by the guidance array 500 is upward. In this case, the guidance array 500 , which actually guides the user to move the handheld portion 16 upward. Therefore, the actuators 21, 22, and 23 are adjustable. The handheld portion 16 operates towards a home position to maximize the user's When the tool 20 is moved upward, the actuators 21, 22, and 23 move the tool 20 to the desired position. The actuator continues to operate to maintain the position (e.g., on the virtual boundary 184). The Eta 21, 22, 23 move backward, such as moving backward towards the home position. , when the user starts cutting the bone, otherwise, the actuators 21, 22 ,23, one or more of which have nearly reached the available travel in each direction. If so, slight movement of the handheld portion 16 will result in the implement controller 28 moving the tool 20. It may not be possible to maintain the desired pose, which may result in inaccurate cutting. There is.

For example, alignment members 502, 504, 528, and 530 may be: Generally, flat, rectangular, or protruding portions are defined to aid in visual reference (e.g., defining an "X" cross section). The shape may be cylindrical, spherical, etc., or a combination thereof. stomach.
[0133] Additionally, throughout the range of motion of the blade support 18 relative to the handheld portion 16 First and second tool alignment members 502, 528 and first and second handle alignment members The first and second members 504, 530 are visible from the proximal end 560 of the blade support 18. and second tool alignment members 502, 528 and first and second handle alignment members 50 4, 530 (which may be collectively referred to as guidance array 500) are attached to blade support 18 and are arranged around the handheld portion 16. In other words, The operator controls the first and second blade supports 18 through a range of motion relative to 16. Tool alignment members 502, 528 and first and second handle alignment members 504, 53 0, the first and second tool alignment members 502, 528 and the The first and second handle alignment members 504, 530 are visible to an operator holding the instrument 14. Additionally, the guidance array 500 is configured to guide all cutting of the instrument 14. In a position (e.g., during a distal femoral resection or a posterior femoral resection), the guidance array 500 to provide a visual indication of the pose of the blade support 18 relative to the handheld portion 16. may be placed.
[0134] During operation of the tool 14, the tool 14, at least one of the tool alignment members 502, 528 and the target plane TP of at least one of the handle alignment members 504, 530 is The actuator 20 is in the target plane TP and the actuators 21, 22, and 23 are in their home positions. The electrodes may be arranged to be aligned in a first spatial relationship when in a fixed position. As shown in the configuration, for example, tool alignment plane 512, handle alignment plane 526, and When the target plane TP is coplanar, the target plane TP, the tool alignment members 502, 528 and The handle alignment members 504, 530 are arranged in a first spatial relationship. Referring to FIG. 1, tool alignment members 502, 528 and handle alignment members 504, 530 are When arranged in one spatial relationship, the "U" shaped tool alignment portion 510 The handle alignment member 524 surrounds the tool alignment member 510 and the handle alignment member 526, respectively. Both upper surfaces 503, 505 of the portion 524 are coplanar, and the actuators 21, 22 , 23 are in their home positions. Maintain the tool 20 in the desired pose. Therefore, the first air is adjusted so that the actuators 21, 22, and 23 have the maximum amount of adjustability. The relationship is such that the tool 20 is aligned with the target plane TP and the actuators 21, 22, 23 are in their respective home positions, and the tool 20 is aligned with the target plane T Pitch, roll and z-axis parallelization on the handheld surgical robot system to keep it on the Provides maximum adjustment in radians (i.e., height).
[0135] In particular, to facilitate visual indication throughout the range of motion of the actuators 21, 22, and 23, To this end, the first and second positions of the plurality of actuators 21, 22, and 23 are At any point between the tool alignment members 502, 528 and the handle alignment members 504, 530 to prevent collision between the tool alignment members 502, 528 and the handle alignment member 50 4,530 are positioned and sized relative to each other. Collectively, the multiple actuators The first and second positions of the eters 21, 22, and 23 are located on the handheld portion 16. The potential range of motion defines the range of potential motion of the blade support 18 relative to the blade. The handheld portion 16 may define a space within which the handheld support 18 can move relative to the handheld portion 16. For example, 52 and 53 show blade supports for handheld portions stacked on top of each other. 18. In one configuration, for example, the blade support 18 is positioned approximately 1 For handheld portion 16 within a space having a height of 50 mm and a width of approximately 115 mm The geometry of the instrument 14 and the limits of the actuators 21, 22, 23 may Based on this, it is believed that the height and width of the space may vary.
[0136] Also, during operation of the instrument 14, the blade support 18 is attached to the handheld portion 16 (FIGS. 18-19). 28) is in a pose that does not provide the desired range of motion. At least one of the row members 502, 528 and at least one of the handle alignment members 504, 530 and may be arranged so as not to be aligned with each other in a second spatial relationship. The second spatial relationship is when the blade support 18 does not provide the desired range of motion for the instrument 14. Provides a visual indication of the pose to the handheld portion 16, thus The tool alignment members 502, 528 and the hand The operating members 504, 530 are aligned in a first spatial relationship. indicates that the user must adjust the pose of the handheld portion 16. In particular, The addition of tool alignment member 528 and second handle alignment member 530 allows for the handheld portion This further aids in providing a visual indication of the pose of the blade support 18 relative to the It functions to:
[0137] In a second spatial relationship, the tool alignment members 502, 528 are aligned with the handle alignment members 504, There are various scenarios where the blade support 18 may not be aligned with 530. For example, It may pitch relative to the handheld portion 16 about a lateral axis 558 (FIG. 18 21), the blade support 18 is rotated about a longitudinal axis 552. It may be rolled against the heald portion 16 (as shown in Figures 22 to 24), and and / or blade support 18 along a vertical axis 554 relative to handheld portion 16. It may move (i.e., rise) by (as shown in Figures 25 to 28). The resulting movement of the blade support 18 relative to the handheld portion 16 in the degrees of freedom. It should be appreciated that other misalignments are possible. Combinations of the above misalignments may be simultaneously For example, the blade support 18 may be attached to the handheld device at the same time. The tool alignment member 502 can be pitched and rolled relative to the hand portion 16. When not aligned with respect to the alignment member 504, the resulting second spatial relationship is The blade relative to the handheld portion 16 may be misaligned in multiple degrees of freedom. Provides a visual indication of the pose of the support 18.
[0138] In some configurations, the first spatial relationship is such that the blade support 18 is aligned with the lateral axis 558 The pitch degree of freedom is aligned with respect to the handheld portion 16 at the center. However, as mentioned above, multiple actuators 21, 22, 23 are attached to the handheld portion 16 to maintain the tool 20 on the target plane TP. The pitch of at least the blade support 18 may be adjusted by, for example, 18 to 21 show that the actuators 21, 22, 23 no longer have maximum adjustability. The blade support 18 is pitched a predetermined amount relative to the handheld portion 16 so as not to The actuators 21, 22, and 23 are no longer at their maximum adjustment. The blade support 18 is pitched relative to the handheld portion 16 so that it is not adjustable. When the tool alignment members 502, 528 are engaged, at least one of the tool alignment members 502, 528 is engaged with the second cavity. In the interposed arrangement, at least one of the handle alignment members 504, 530 and The second spatial arrangement may include a pitch relationship. is the pitch of the blade support 18 relative to the handheld portion 16 about the lateral axis A visual indication of the size of the
[0139] For example, as shown in FIGS. 18-21, the distal portion 542 of the handle alignment member 504 , along the longitudinal axis 552 of the handle alignment member 504 in the direction of pitch. The proximal portion 544 of the alignment member 504 (shown as distance D2) is closer to the blade plane B. Further from P (shown as distance D1), the tool alignment member 502 and the handle The dollar alignment members 504 may be arranged in pitch relationship, for example, as best shown in FIG. As a result, the actuators 21, 22, 23 no longer have maximum adjustability. The second tool alignment member 528 is pitched relative to the second handle alignment member 530 so that When engaged, the longitudinally distal portion 542 of the second handle alignment member 530 rotates in the pitch direction. The second handle is aligned along the longitudinal axis 552 of the second handle alignment member 530 in the The alignment member 530 is positioned at a distance D4 from the longitudinally proximal portion 544 of the alignment member 530. the distance from the ground plane BP (shown as distance D3). The blade support is so adjusted that the actuators 21, 22, 23 no longer have maximum adjustability. When the handle aligning members 504, 505 are pitched relative to the handheld portion 16, One end of 28 is further along the longitudinal axis of tool 20 in the direction of movement than the other end. Therefore, the alignment members 502, 504, 528, and 530 are arranged such that the blade support 18 is aligned with the handheld portion 16. The tool alignment members 502, 528 and handle alignment member 504 do not have the desired range of motion. , 530 are aligned in a first spatial relationship. A visual cue may be provided that the pose must be adjusted, allowing the apparatus 14 to adjust to its maximum Offer possibilities.
[0140] In other configurations, the first spatial relationship is such that the blade support 18 is aligned with the longitudinal axis 55 2 is aligned in the roll degree of freedom relative to the handheld portion 16. The plurality of actuators 21, 22, 23 may provide a visual indication of the tool 20. At least blade support for handheld portion 16 to maintain it over target plane TP For example, FIGS. 22 to 24 show a plurality of arms. The actuators 21, 22, 23 are then lowered by a predetermined amount so that they no longer have maximum adjustability. The blade support 18 is shown rolled relative to the handheld portion 16. The blade support 18 is then rotated so that the actuators 21, 22, 23 no longer have maximum adjustability. When the tool alignment members 502, 505 are rolled relative to the handheld portion 16, At least one of the handle alignment members 5 and 28 is arranged in the second spatial arrangement. The second spatial arrangement includes the role relationship. The roll relationship is the roll of the brake relative to the handheld portion 16 about the longitudinal axis 552. A visual indication of the size of the roll of braid support 18 may be provided.
[0141] For example, as shown in FIGS. 22-24, the distal portion 546 of the handle alignment member 504 The handle alignment member 504 is aligned along a lateral axis 558 of the handle alignment member 504 in the direction of roll. The blade plane BP is closer to the proximal portion 548 of the row member 504 (shown as distance D2). When the distance from the tool alignment member 502 is greater than the distance from the tool alignment member 502 (shown as distance D1), the tool alignment member 502 and the hand The roll alignment members 504 may be arranged in a roll relationship. a laterally proximal portion of the second handle alignment member 530 along a lateral axis 558 in the The second hand is farther from the blade plane BP than min 548 (shown as distance D4). 10 shows the laterally distal portion 546 (shown as distance D3) of the alignment member 530. Still referring to FIG. 24, the first handle alignment member 504 is a second spatial relationship of the handle alignment member 502 to the second handle alignment member 530; The combination of the first tool alignment member 528 with the second spatial relationship is merely The first tool alignment member 502 is aligned with the handheld portion 1 rather than the first tool alignment member 504. 6. In particular, the first The first handle alignment member 504 and the second handle alignment member 530 are aligned with the handle alignment plane 5 26 (shown in FIG. 24) may be cumulatively defined, and the handle alignment plane 526 may be The tool adjustment is performed so that the number of actuators 21, 22, 23 no longer has maximum adjustability. The blade support for the handheld portion may be rolled relative to the row plane 512. 18. Thus, the operator can easily see the position of the blade support 18. Another visual indication is provided that the handheld portion 16 does not have an optimal range of motion. In other words, the actuators 21, 22, 23 are no longer at their maximum adjustable position. The blade support 18 is rolled relative to the handheld portion 16 so as to have no In this case, one side of the handle alignment members 504, 528 is in the direction of deviation. 04,528 is moved further from the blade plane BP than the other side. The arrangement of alignment members 502, 504, 528, 530 in a roll relationship provides a blade support If the body 18 does not have the desired range of motion relative to the handheld portion 16, the tool alignment member 502 and the operator aligns the handle alignment member 504 in a first spatial relationship. Provide visual indication that the pose of the handheld part 16 should be adjusted. This provides maximum adjustability for the instrument 14.
[0142] In an additional configuration, the first spatial relationship is such that the blade support 18 is aligned with the vertical axis 554. The center does not have any vertical displacement (i.e., height) relative to the handheld portion 16. The plurality of actuators 21, 22, 23 may provide a visual indication that the tool The blade support 1 is attached to the handheld portion 16 to maintain the blade 20 on the target plane TP. 25 to 28 show a plurality of The handheld device is then rotated so that the actuators 21, 22, 23 no longer have maximum adjustability. 1 shows the blade support 18 raised a predetermined amount relative to the blade portion 16. The blade supports are then moved so that the actuators 21, 22, 23 no longer have maximum adjustability. When the carrier 18 is raised relative to the handheld portion 16, the tool alignment members 502, At least one of the handle alignment members 528 is arranged in the second spatial arrangement. 504, 530. The rows may include a height relationship, which may include a blade support relative to the handheld portion 16. A visual indication of the height of the body 18 may be provided. For example, as shown in FIGS. As shown, the tool alignment member 502 and the handle alignment member 504 are The height when the handle is moved above the handle alignment member 504 in the height direction at a distance D1. 26 and 28 show a second example of the arrangement of the first and second electrodes at a distance D3. 10 shows a second handle alignment member 530 moved above the tool alignment member 528. Therefore, the arrangement of the alignment members 502, 504, 528, and 530 in terms of height is , the blade support 18 does not have the desired range of motion relative to the handheld portion 16, and the tool The alignment members 502, 528 and the handle alignment members 504, 530 are in a first spatial relationship. The operator must adjust the pose of the handheld portion 16 so that it is aligned with the This may provide a visual indication that the instrument 14 is in a fully adjusted position, providing maximum adjustability for the instrument 14.
[0143] In view of the above discussion, the guidance array 500 provides many benefits to the operation of the instrument 14. For example, the guidance array 500 may be required to ascertain the pose of the blade support 18 relative to the handheld portion 16 In other words, the blade support relative to the handheld portion 16 is reduced. The operator essentially shifts their focus to receive visual instructions for the posture of the body 18. guidance array so that there is no need to adjust (e.g., rotate) their heads. The guidance array 500 is positioned so that the tool is substantially within the operator's line of sight. 20. At the same time, the guidance array 500 is positioned substantially in the line of sight of the operator. While the guidance array 500 is located within the Towards the proximal portion 560 of the tool support so that the distal tip of tool 20 is visible. This allows the user to concentrate on cutting and aligning at the same time. In other words, the guidance array 500 allows the user to have an unobstructed view of the surgical site and the tool 20. The device is positioned a specific distance from the distal tip of the tool 20 to have a good view. Additionally, the guidance array 500 is configured to position the blade support 18 relative to the handheld portion 16. and providing the operator with an easily identifiable visual indication of the speed of the Reduces the need for auxiliary components (e.g., auxiliary navigation displays). Additionally, guidance array 500 has minimal parallax. 00 provides visual instructions primarily through mechanical structures, making it less appealing than electronic navigation. In comparison, there is no delay in providing visual indication of movement.

In this configuration, the term "intersects" refers to the ability of the handheld surgical system to operate within appropriate tolerances. When viewed from the proximal end 560 of the system 10, at least a portion of the tool alignment member 602 and At least a portion of the handle alignment member 604 is substantially aligned (as described above). Referring to FIG. 32, the tool alignment portion 610 and the handle The alignment portions 624 include markings in the form of a first color 666 and a second color 668, respectively. The marks (666, 667) on the tool alignment portion 610 and the handle alignment portion 624 may be used. 668) provides a visual indication of the alignment of the blade support 18 relative to the handheld portion 16. For example, the handheld device (as shown in Figure 32) is used by an operator. When viewed from the proximal end 560 of the device 14, the marks (666, 668) overlap. When the marks (666, 668) are aligned, the operator can 8 has the greatest range of adjustability relative to the handheld portion 16. In particular, marks (666, 668) indicate that the blade support 18 is a handheld portion. 16 each having a length that defines the appropriate overlap tolerance with an optimum range of motion. The tool alignment member 602 and handle alignment member 604 are aligned with the blade (as described above).

With particular reference to FIG. 34, the tool alignment portion 610′ and The bundle alignment portion 624' guides the guidance array 600' from the proximal end 560 of the instrument 14. The size should be such that the operator can easily identify that they are aligned when looking at them. The blade support 18 may be dimensioned to allow optimal movement relative to the handheld portion 16. Also, the tool alignment member 602' and handle The alignment member 604' aligns the blade support 18 relative to the handheld portion 16 (as described above). If they are in a pose that does not provide the desired range of motion, In particular, the guidance array 600' may be positioned so that it is not aligned with the handheld device. To provide further indication of the pose of the blade support 18 relative to the handle portion 16, It may include two tool alignment members 628' and a second handle alignment member 630'.

The tool alignment member 602'' and the When the tool alignment portion 604 and the handle alignment member 604'' are disposed in a first spatial relationship, 10'' and handle alignment portion 624'' may be offset from the blade plane BP. For example, as shown in FIG. 36, tool alignment portion 610'' and handle alignment portion 624 '' is the plane defined between the blade plane BP and the grip 72 of the handheld portion 16. In other words, in the configurations shown in FIGS. tool alignment member 602'' and so that they are aligned (i.e., substantially parallel). When the handle alignment member 604'' is disposed in the first spatial relationship, the tool alignment portion 61 0'' and handle alignment portion 624'' are not coplanar with the blade plane BP. While the tool alignment member 602'' and the handle alignment member 604'' are in a first spatial relationship, When placed in engagement, the tool alignment portion 610'' and the handle alignment portion 624'' are BP, and the tool 20 is aligned with the target plane TP and is actuated. The controllers 21, 22, and 23 provide a visual indication that they are in their home positions. Also, the blade support 18 (as described above) provides the desired movement relative to the handheld portion 16. When in a pose that does not provide a range of motion, the tool alignment member 602'' and the handle alignment member The materials 604'' may be arranged so as not to be aligned in a second spatial relationship.

To provide further guidance for the pose of the second tool alignment member 628'' and the second The handle alignment member 630'' may include a handle alignment member 630''.
[0149] In particular, the guidance array 600'' provides blade support for the handheld portion 16. To provide further instruction for the 18 poses, a second tool alignment member 628'' and For example, the plurality of actuators 21, The blade support 18 is shown in FIG. 37 so that 22, 23 no longer have maximum adjustability. The handheld portion 16 is rolled a predetermined amount away from the attached configuration. One side of the handle alignment member 604'', 628'' is provided for aligning the handle in the direction of deviation. Move the members 604'', 628'' further from the tool alignment plane 512 than the other side. In other words, the handle alignment portion 624'' is aligned with the tool alignment portion 624 in the direction of deviation. 10'' away from the tool alignment portion 610'' and the handle alignment portion 624'' is not aligned so that the blade support 18 does not move as desired relative to the handheld portion 16.

[0150] 38 and 39 show further configurations of the guidance array 600'''. In the illustrated configuration of the tool alignment array 600''', the tool alignment members 602''' The handle alignment member 604''' includes the alignment portion 610''', and the handle alignment member 604''' includes the handle alignment portion 624 In particular, however, the structures shown in Figures 12 to 28 and Figures 35 to 37 Unlike the handle alignment member 604''', the tool alignment member 602''' is attached to one side of the handle alignment member 604'''. In contrast to the configurations shown in Figures 12 to 28 and Figures 39 to 42, the tool alignment Member 502 aligns with both the distal and proximal ends of handle alignment member 504. As shown in the configuration shown in FIG. 1, for example, the tool alignment portion 610′″, the handle alignment portion Once the target plane TP and the tool alignment member 624''' are aligned, the target plane TP and the tool alignment member 602''' and handle alignment member 604''' are disposed in a first spatial relationship, The actuator 20 is aligned with the target plane TP and the actuators 21, 22, and 23 are It also provides a visual indication that the blade 18 is in the home position (as described above). 2) when in a pose that does not provide the desired range of motion for the handheld portion 16; tool alignment member 602''' and tool alignment member 602''' such that they are not aligned in the second spatial relationship. and handle alignment member 604'''. In particular, guidance array 600' '' provides further indication of the pose of the blade support 18 relative to the handheld portion 16. To this end, a second tool alignment member 628''' and a second handle alignment member 630 May contain '''.
[0151] In particular, the guidance array 600''' provides blade support for the handheld portion 16. To provide further indication of the pose of the body 18, a second tool alignment member 628''' and and a second handle alignment member 630'''. For example, multiple actuators 39 so that 21, 22, 23 no longer have maximum adjustability. The blade support 18 is rolled a predetermined amount relative to the handheld portion 16 so that the blade support 18 is separated from the handheld portion 16. When the handle alignment member 604''', 628''' is rotated, one side of the handle alignment member 604''', 628''' is rotated in the direction of deviation. The handle alignment members 604''', 628''' are positioned further from the blade plane BP than the other side of the handle alignment members 604''', 628'''. In other words, the handle alignment portion 624''' is moved in the direction of deviation. Moves away from tool alignment portion 610''' and moves toward tool alignment portion 610''' and the handle alignment portion 624''' is not aligned, and the blade support 18 is in the handheld portion. 16 and tool alignment members 602''', 628''' and the handle alignment members 604''', 630''' are aligned in a first spatial relationship. The operator must adjust the pose of the handheld portion 16 to It provides a visual cue and provides maximum adjustability for the instrument 14. Similarly, the second tool alignment portion The first handle alignment member 628''' and the second handle alignment member 630''' have pitch and height degrees of freedom. provides further indication of the pose of the blade support 18 relative to the handheld portion 16. Provide.
[0152] In particular, as shown in the configurations shown in FIGS. 29 to 39 and 51, the tool alignment member 6 02, 602', 602'', 602''' are removably coupled to the blade support 18 The tool tracker 574 may be integrally formed with the surgical navigation system. The tool alignment members 602, 602', 602'', 602''' are aligned with the tool tracker 574. Forming the blade support 18 integrally with the blade 18 reduces the mounting space required. This allows the tool tracker to be closer to the tip of the tool 20, resulting in more accurate surgical navigation. The tool tracker 574 is attached to the cross member 582. The wall 580 may include walls 580, each side wall 580 having one or more of a plurality of markers 584. In some configurations, the markers are arranged in a mirror image configuration on each sidewall 580. The sidewall 580 may be formed to match the profile of the blade support 18. Additionally, in some configurations, the markers 584 may be active, passive, or a combination thereof. In other configurations, the marker 584 may be 2 to improve line of sight with tool alignment members 602, 602', 602'', 602'' '. To attach the tool tracker 574 to the blade support 18, The tool tracker 574 may include a guide slot 576, and the blade support 18 may include The distal end of the blade support 18 may include a guide rail 578 (shown in FIG. 35). The guide slots 576 of the tool tracker 574 are guided by the guides of the blade support 18. It is sized to accept the guide rail 578 and the tool tracker 574 18. The connector 14 is connected to the distal end of the card support 18.
[0153] Additionally, the tool alignment member 602 and / or the handle alignment member 604 may be one or more may include multiple visual indicia. For example, as shown in Figures 32 and 34, In this configuration, the tool alignment member 602 includes at least a first visual indicia 562, The guide alignment member 604 includes at least a second visual indicia 564. In particular, the first visual indicia 56 2 is visually distinguishable from the second visual indicia 564. For example, see FIGS. In the version shown in FIG. 1, the first visual indicia 562 is located on the tool alignment member 602 and The handle alignment member 604 is not aligned (i.e., in the second spatial arrangement) ) may be positioned so as to be visible from the proximal end 560 of the handheld portion 16. Second visual indicia 564 indicates that tool alignment member 602 and handle alignment member 604 are aligned. When aligned (i.e., in a first spatial arrangement), the proximity of the handheld portion 16 Therefore, the first visual indicator 562 is positioned so that it is visible from the distal end. and a second visual indicator 564 indicates tool alignment relative to the handle alignment member 604. Provides the operator with an easily identifiable visual indication of the alignment of member 602. In John, visual cues can be one or more visual cues (e.g., patterns, lights, For example, referring to FIG. 32, the visual indicia may include colored It may include marks 666 and 668.
[0154] For example, in another configuration as shown in FIGS. 47-48, tool alignment member 502 and The handle alignment member 504 includes a first visual indicia 562 and a second visual indicia 566, respectively. For example, the first visual indicia 562 may be a first color 566 and the second visual indicia The target 564 may be a second color 568. In this configuration, the first color 566 is When the screw alignment member and the handle alignment member are aligned (FIGS. 35, 37 and 38), 40) and a tool alignment member 504 and a handle alignment member 504 are adjacent to each other. At least one of the second visual indicia 564 is visible along the bordering edge of the tool. When alignment member 502 and handle alignment member 504 are misaligned (as best seen in FIG. 40), tool alignment member 504 and handle alignment member 504 (shown) at adjacent edges To facilitate this configuration, the upper surface 503 of the tool alignment member 502 and The top surface 505 of the handle alignment member 504 may include a first visual indicia 562. The side 570 of the tool alignment member 502 and the side 572 of the handle alignment member 504 are The second view is taken when the wheel alignment member 502 and the handle alignment member 504 are not aligned with each other. The actuator may include a second visual indicia 564 so that the first visual indicia 564 appears. 21, 22, 23 to provide an indication that one or more of the The visual indicia 562, 564 indicate that the tool alignment member 502 and the handle alignment member 504 are aligned. To quickly identify if the tool is out of alignment, the operator must first This allows for quick differentiation of the surface of the handle alignment member 504. For example, as shown in FIG. As such, when the tool alignment member 502 and the handle alignment member 504 are not aligned, A second visual indicia 564 (in the form of a second color 568 and located on side 572) At least one of the actuators 21, 22, 23 is visible. provides an indication that the plurality has moved from the home position.
[0155] 42 and 43, the instrument 14 includes a tool alignment member 502, a handle alignment member 504, and a Any suitable location within the operator's line of sight, such as member 504 or blade support 18 The light source 586 may include a light emitter 586 such as an LED. may be configured to be illuminated when the blade support 18 has a desired range of motion. and visual confirmation that the handheld portion 16 is within a specified alignment range with the target plane TP. For example, light 586 may indicate that actuators 21, 22, and 23 are in the first configured to indicate that the sensor is in a spatial arrangement (i.e., has a desired range of motion) Alternatively, the light emitters 586 may be illuminating when the blade supports 18 are in the second spatial arrangement. For example, the handheld portion 16 may be configured to illuminate when movement of the handheld portion 16 is required. When the first visual indicator 201 is activated to indicate that The indicator 201 indicates that one or more of the actuators 21, 22, and 23 are home. Too far away from the position and not aligning the tool alignment member with the handle alignment member , indicating that the handheld portion 16 needs to be moved.
[0156] In some examples, the controller may determine the commanded positions of the actuators 21, 22, 23. and controlling the light emitter 586 based on the available movement of the actuators 21, 22, and 23. For example, the first color may be a first color within the actuation range of the actuators 21, 22, and 23. The second may be based on the range of travel and the commanded position of the actuators 21, 22, 23. The color of the second range of movement of the actuators 21, 22, 23 is different from the first range of movement. 2 and the commanded position of the actuators 21, 22, 23. A third color may also be included to represent a third range of movement of the actuators 21, 22, 23 within their available travel. The third range of movement may be different from the second range of movement. For example, the first color may be red. This allows the commanded actuator 21, 22, 23 closest to the outer limit of available travel to be The second color, yellow, correlates to the position of the target and indicates movement further away from the outer limits of the available movement. The third color is green, which correlates to the commanded positions of the actuators 21, 22, 23. The commanded position of the actuators 21, 22, 23 is far from the limits of the available range of movement. This indicates that
[0157] In a further example, the color associated with the light emitter 586 is determined by a plurality of actuator parameters. , whereby the light 586 may indicate to the user that at least one actuator The first represents the amount of movement required to bring the sensors 21, 22, and 23 to the commanded position. and a handheld portion 16 for bringing the tool 20 into the working range of the actuator. and a second color representing the direction required to move the The color of the arrow may correspond to the outermost range of available movement (i.e., relative to the commanded position). the fewest remaining moves available), the second color corresponds to the middle range of available moves The first color may correspond to the innermost range of available moves (i.e., (Most remaining movement available relative to the commanded position). In some instances, the light source 5 86 is configured to be divided into two or more parts. Each part is It may be illuminated in different states to indicate the desired direction of movement of the handheld portion 16. In some versions, the illumination of the upper and lower portions of the light source 586 is controlled by the handheld. The same is operated based on the commanded position and available movement of the hand portion 16. It is okay to do so.
[0158] Alternatively, the light 586 or other indicia may indicate one or more configurations of the commanded pose. The system may be controlled based on one or more ranges of motion in a particular degree of freedom. More specifically, the light 586 or other indicia may indicate the pitch configuration of the commanded pause. Alternatively, or in combination, the pitch range of the element and the motion may be controlled. , the light emitter 586 is based on the roll component of the commanded pose and the roll range of the movement. The pitch and roll ranges of motion may be controlled by a series of superimposed ranges. The control system 60 determines whether the pitch component of the commanded pose is equal to the pitch of the movement. The roll component of the commanded pose is within the innermost range of the movement roll. When the light source is within the innermost range of the color range, the light emitter may be controlled to emit a first color. Alternatively, the control system 60 may control the light emitter to emit light of a second color or to emit light of a second color. The pitch component of the commanded pose is in a range relatively outside the pitch range of the movement, or When the roll component of the commanded pose is in a range relatively outside the roll range of the movement, By controlling the light 586 in this manner, the light signature , the user is in a good pose in terms of pitch and roll or the user is in a good pose in terms of pitch and roll It can also indicate that one of the roles needs to be adjusted. The stem 60 also determines whether the height component of the commanded pose is within the innermost range of the height range of the movement. The first color may be further emitted only if a further condition exists, such as when the first color is within a predetermined range. Additionally, the control system 60 may be configured to control one of the pitch, roll, or height components. If either of the is outside its respective innermost range of motion, it emits a second color of light. Alternatively, the light emitters 586 may be controlled to block power to the light emitters 586. Although roll and roll are mentioned here, the light emitter 586 may have other degrees of freedom relative to one another. Control based on the components of the commanded pose and their respective ranges of motion can be done.

In some configurations, the number of the nuclei is 2 or more, 5 or more, 10 or more, Or even multiple shroud landmarks 702 may be provided. As the handheld portion 16 moves relative to the shroud landmarks 18, the shroud landmarks move relative to each other. The movement of 702 provides a visual indication of the pose of the blade support 18 relative to the handheld portion 16. 45, the instrument 14 is detachably mounted in a handheld portion 16. The shroud may include one or more shroud alignment members 706 operably coupled thereto. In some configurations, the instrument 14 includes at least two shroud alignment members 706. The shroud alignment member 706 may be transparent and may have a shroud alignment mark 708. For example, referring to FIG. 47, shroud alignment marks 708 may be included when multiple The actuators 21, 22, 23 are in their home positions and therefore the instrument 1 In some configurations, 2 or more, 4 or more may indicate whether the patient has an optimal range of motion. Alternatively, multiple shroud alignment members 706 may be provided. For example, see FIGS. 50 provides a further visual indication of the pose of the blade support 18 relative to the handheld portion 16. A handheld surgical robot system including a second shroud alignment member 714 for providing Shows the stem.

Also, similarly, the blade support relative to the handheld portion may include a visual indicator 564. The first visual field is adjusted to provide the operator with a readily identifiable visual indication of the pose of the body 18. The visual indicia 562 may be visually distinguishable from the second visual indicia 564. For example, The first visual indicia 562 may be a first color and the second visual indicia 564 may be a second color. In this configuration, the first color is displayed when the blade support 18 is in the first position (all That is, when the actuators 21, 22, and 23 are in their home positions. and the second color is visible when the blade support 18 is in a second position (i.e., the blade When the support 18 does not have an optimal range of motion relative to the handheld portion 16, this is visible.
[0163] In another configuration shown in Figures 54-77, the instrument 14 also includes a guidance array 900. The guidance array 900 controls the tool relative to the handheld portion 16 during operation of the instrument 14.

The indicator may be of any suitable shape or configuration that provides an indication to an operator user. For example: 54 to 77, the handle alignment member 904 has a handle alignment protrusion 906. The handle alignment protrusion 906 extends toward the tool mount 18a. 54 to 77, the handle alignment protrusion 906 is At least a portion 908 of the protrusion 906 is aligned with the longitudinal axis 9 of the tool 20 / tool support 18. 10 and shaped to be disposed at an oblique angle relative to the lateral axis 912. For example, the handle alignment protrusion 906 is aligned with the longitudinal axis 91 of the tool 20 / tool support 18. 0 and a handle alignment edge 914 disposed at an oblique angle relative to the lateral axis 912. Handle alignment protrusions relative to the longitudinal axis 910 and the lateral axis 912 The "oblique" angle of 906 may be, for example, a slant angle between both the longitudinal axis 910 and the lateral axis 912. The alignment of the handle alignment protrusion 906 at an angle greater than 0 degrees and less than 90 degrees relative to the For example, the tool alignment protrusion 906 may include a longitudinal and lateral axis 910 , 912. A tool alignment edge 914 may be defined that is at a 45 degree angle relative to the edge 912.
[0165] In one configuration, for example, as shown in FIGS. 54-77, a handle alignment member 90 4 may define a hook-shaped handle alignment protrusion 906. The projection 906 swivels inwardly toward the tool support 18 to define the oblique angle. The handle may define a curved handle alignment edge 914 that loops over the handle. The configuration shows a hook-shaped handle alignment protrusion 906, but polygonal edges, stepped edges, etc. Any suitable edge that defines an oblique angle is contemplated, including but not limited to: In particular, as will be explained in more detail below, the longitudinal direction of the tool 20 / tool support 18 The oblique angle of the handle alignment protrusion 906 relative to the axis 910 and the lateral axis 912 is: Simultaneously, the pose of the tool support 18 relative to the handheld portion 16 in multiple degrees of freedom is calculated. This may provide the user with a more accurate identification.
[0166] In some configurations, such as those shown in Figures 54-57, the actuator assembly When the actuators 21, 22, and 23 of the hand 400 are at their home positions, At least a portion of the tool alignment protrusion 906 and the tool plane BP may be aligned, Provide a visual indication that the support 18 has an optimal range of motion for the handheld portion 16. In some configurations, the term "aligned" refers to the handle At least a portion of the alignment protrusion 906 is substantially aligned with the tool plane BP within an appropriate tolerance. In particular, in the home position, the actuator The amount of adjustability of the actuators 21, 22, 23 of the eter assembly 400 is determined by the tool 20 is maximized to maintain the desired pose. In some cases, the handle alignment The alignment of at least a portion of the protrusion 906 with the tool plane BP is greater than 99 percent. may be aligned to 90 percent or more; may be aligned to 70 percent or more In other examples, the alignment may be more than 60 percent. Alignment is achieved by 1 percent deviation from the target pose in each individual degree of freedom, 5 percent deviation from the target pose, 10 percent deviation from the target pose, or is a specified deviation from the target pose, such as within 20 percent or more of the target pose. Similarly, proper alignment may be achieved in each individual degree of freedom. Within 1mm of the target pose, within 2mm of the target pose, or even 5mm of the target pose In addition, proper alignment may be achieved by adjusting the target position in roll and / or pitch. deviation of more than 1 degree from the target pose, deviation of more than 5 degrees from the target pose, deviation of more than 15 degrees from the target pose or even a deviation of 30 degrees or more from the target pose.
[0167] Conversely, when the handheld portion 16 is in a pose that does not provide an optimal range of motion, the tool The handle plane BP and the handle alignment protrusion 906 are configured not to be aligned, and the handle the handheld portion 16 is in a pose that does not provide an optimal range of motion for the tool support 18; Therefore, it provides a visual indication that adjustments need to be made by the operator (see below). (This is described in more detail below.) In some configurations, the guidance array 900 54-77. The tool alignment member 902 may then extend from the tool support 18. 902 provides a visual indication of the pose of the tool plane BP relative to the handle alignment member 904. For example, the tool alignment member 902 may have any shape or configuration that allows for , may include a tool alignment protrusion 916 extending toward the tool mount 18a. 54-77, similar to the handle alignment protrusion 906, the tool alignment protrusion 916 is the longitudinal axis 910 and the lateral axis 912 of the tool 20 / tool support 18. In some configurations, the periphery of ... For example, the tool alignment protrusion 916 is aligned with the longitudinal axis 910 and lateral axis 912 of the tool 20. A tool alignment edge 918 may be defined that is oblique to the adaxial line 912 .
[0168] The optimal range of motion may be the maximum range of motion in one, two, three or more degrees of freedom. The optimum range of motion does not necessarily have to be the maximum range of motion, but rather the maximum The desired range of motion for the preferred pose of the tool support for a particular cut, or other pre-planned virtual objects such as drawn sections or planned axes. The optimal range of motion is the center of the range of motion in one or more degrees of freedom. It need not be the center of the range of motion in one, two or three degrees of freedom in a given configuration. That's fine.

The second spatial relationship 952 may be such that the needle alignment protrusions 902, 942 are positioned relative to the instrument 14. pose the tool support 18 relative to the handheld portion 16 in a way that does not provide the desired range of motion to provide a visual indication that the instrument 14 is To do this, the tool alignment protrusions 916, 944 and the handle alignment protrusions 906, 936 are aligned with the first The operator positions the pointer of the handheld portion 16 so that they are aligned in spatial relationship 950. In particular, the second tool alignment member 942 and The addition of the second handle alignment member 934 provides tool support for the handheld portion 16. It serves to further assist in providing visual instructions for the 18 poses. To facilitate visual cues throughout the actuator's range of motion, The first position of each of the plurality of actuators 21, 22, 23 of the rotor assembly 400 The tool alignment members 902, 942 and the handle alignment members 904, 906 may be moved at any point between the first and second positions.

For example, the tool support 18 is oriented along a lateral axis 912 (see FIGS. 59-62). 1) may be pitched relative to the handheld portion 16 around the tool support 1 8 is a handheld portion about a longitudinal axis 910 (shown in FIGS. 63-66). 16 and / or the tool support 18 may be 6 along a vertical axis 954 (i.e., height) relative to the In other degrees of freedom, the tool support 16 is It should be recognized that other misalignments resulting from the movement of 8 are possible. It should also be appreciated that combinations of alignments may occur simultaneously. For example, tool support 18 The handle can be simultaneously pitched and rolled relative to the handheld portion 16.

The tool support 18 is aligned in the pitch degree of freedom relative to the heald portion 16. However, the above-mentioned pitch relationship may include a first pitch relationship 956 that provides a visual indication that Thus, the actuators 21, 22, and 23 of the actuator assembly 400 are a tool support for the handheld portion 16 to maintain the tool 20 at the target plane TP; 59 to 62. For example, The hand is moved so that the actuators 21, 22, 23 no longer have maximum adjustability. The tool support 18 is shown pitched a predetermined amount relative to the heald portion 16. The tool support is so that the actuators 21, 22, 23 no longer have maximum adjustability.

Provides a visual indication that the part 16 is aligned in the roll degree of freedom The plurality of actuators 21, 22, 23 may include a first roll relationship 968. axially with respect to the handheld portion 16 to maintain the target plane TP. It may be configured to adjust at least the roll of the tool support 18 around 0. For example, FIGS. 63 to 66 show that the plurality of actuators 21, 22, and 23 are no longer at their maximum adjustable state. The tool support is rolled relative to the handheld portion 16 by a predetermined amount so as to have no The actuators 21, 22, 23 no longer have maximum adjustability. When the tool support 18 is rolled relative to the handheld portion 16, The tool alignment protrusions 906, 936 are aligned with the tool plane in a second spatial arrangement 952. It may not be aligned with the BP and / or tool alignment protrusions 916, 944. The second spatial arrangement 952 may include a second roll relationship 970. 9. 0 is the tool support 18 relative to the handheld portion 16 about the longitudinal axis 910. The roll may provide a visual indication of the size and direction of the roll.
[0191] For example, as shown in FIGS. 63 to 66, the outer portions of the handle alignment protrusions 906 and 936 The portion 972 is located closer to the inner portion 974 of the handle projections 906 and 936 in the direction of roll. When away from the tool plane BP and / or the tool alignment protrusions 916, 944, The handle alignment protrusions 906, 936, the tool plane BP and / or the tool alignment protrusion 91 6,944 may be disposed in a second roll relationship 970. In particular, referring to FIG. First handle alignment relative to tool plane BP and / or first tool alignment protrusion 916 A second spatial relationship 952 of the protrusion 906 and the tool plane BP and / or the second tool a second spatial relationship 952 of the second handle alignment protrusion 936 relative to the alignment protrusion 944; The combination of is simply relative to the tool plane BP and / or the first tool alignment protrusion 916. The second spatial relationship 952 of the first handle alignment protrusion 906 is such that the handheld portion 1 6. A further visual indication of the pose of the tool support 18 relative to the
[0192] In particular, the addition of the second tool alignment member 942 and the second handle alignment member 934 improves the tool alignment. Another point of view is that the support 18 does not have an optimal range of motion relative to the handheld portion 16. In other words, referring to Figures 63 to 66, multiple The tool support is so that the actuators 21, 22, 23 no longer have maximum adjustability. When the handle 18 is rolled relative to the handheld portion 16, the handle alignment protrusions 906, One side of the handle alignment protrusion 936 is opposite to the other of the handle alignment protrusions 906 and 936 in the direction of roll. the tool plane BP and / or the tool alignment protrusions 916, 944. For example, as shown in FIGS. 63 to 66, the first handle alignment protrusion 90 The outer portion 972 of the first handle 970 is below the first tool alignment protrusion 916, while the outer portion 972 of the second handle 970 is below the first tool alignment protrusion 916. an outer portion 972 of the tool alignment protrusion 916 above the second tool alignment protrusion 944; The handheld portion 16 is rolled clockwise relative to the tool support 18. Therefore, the operator can adjust the tool 14 to a position with maximum adjustability. The feeling that the handheld portion 16 should be adjusted clockwise to return Therefore, the second roll relationship 970 is such that the tool support 18 does not have a desired range of motion relative to the handheld portion 16 and is in a first spatial relationship 950 Handle alignment protrusions 906, 936, tool plane BP and / or tool alignment protrusion 9 The operator must adjust the pose of the handheld portion 16 so that the 16,944 is aligned. This may provide a visual cue that the instrument 14 should be adjusted and provides maximum adjustability.
[0193] In an additional configuration, the first spatial relationship 950 is such that the tool support 18 is aligned with the vertical axis 95 Any vertical movement (i.e., height) relative to the handheld portion 16 along the The actuator may include a first height relationship 978 that provides a visual indication that the actuator is not The plurality of actuators 21, 22, 23 of the assembly 400 move the tool 20 to a target plane T At least the height of the tool support 18 relative to the handheld portion 16 is maintained at P For example, FIGS. 67 to 70 show a plurality of actuators 21 , 22, 23 are adjusted relative to the handheld portion 16 so that they no longer have maximum adjustability. 1 shows the tool support 18 raised by a certain amount. The tool support 18 is positioned so that the handheld portion 16 no longer has maximum adjustability. When raised relative to the handle alignment protrusions 906, 936, the handle alignment protrusions 906, 936 are aligned with the second spatial arrangement 9 52 and the tool plane BP and / or tool alignment protrusions 916, 944, respectively. The second spatial arrangement 952 includes a second height relationship 980. The second height relationship 980 is the height of the tool support 18 relative to the handheld portion 16. A visual indication of the size of the
[0194] For example, as shown in FIGS. 67 to 70, the handle alignment protrusions 906 and 936 are 916, 944 downward in the direction of the tool plane BP and / or the tool alignment protrusion 916, 944. When the handle alignment protrusions 906, 936, the tool plane BP and / or the tool The rule alignment protrusions 916, 944 may be disposed at a second height relationship 980. For example, the actuators 21, 22, 23 may be adjusted so that they no longer have maximum adjustability. When the handle support 18 is raised relative to the handheld portion 16, the handle alignment protrusions 906, 936 are aligned along a vertical axis 954 in the height direction to the tool plane BP and / or The tool alignment protrusions 916 and 944 are located above or below the tool alignment protrusions 916 and 944. Therefore, the second height relationship Handle alignment protrusions 906, 908 relative to tool alignment protrusions 916, 944 at 980 The arrangement of 36 allows the tool support 18 to have an optimal range of motion relative to the handheld portion 16. 9. The handle alignment protrusions 906, 936 are aligned with the tool plane in a first spatial relationship 950. The operator must ensure that the handle is aligned with the BP and / or tool alignment protrusions 916, 944. providing visual indication that the pose of the handheld portion 16 should be adjusted; Provides maximum adjustability for the instrument 14. For example, tool alignment protrusions 916, 944 are shown in FIG. 67-70, handle alignment protrusions 906, 903 on each side of the instrument 14 6 and handle to place the instrument 14 in a position with maximum adjustability. The handheld portion 16 is raised to align the handheld portion 16 with the tool support 18. It provides a visual indication to the user that it needs to be moved.
[0195] It will be appreciated from the above discussion that the guidance array 900 provides many benefits to the operation of the instrument 14. For example, the handle alignment protrusions 906, 936 (and therefor) The handle alignment edges 914, 940 defined by this are used to at an oblique angle relative to the longitudinal axis 910 and the lateral axis 912 defined by the body 18. At an oblique angle relative to the longitudinal axis 910 and the lateral axis 912. The arrangement of the portions 908, 938 of the handle alignment protrusions 906, 936 allows for multiple free The handle angle is relative to the tool plane BP and / or the tool alignment protrusions 916, 944. The benefit of this is that it allows the operator to recognize the alignment of the dollar alignment protrusions 906, 936. Provide points.
[0196] For example, as shown in Figures 71-75, in some configurations, the actuator assembly The assembly 400 is configured to have at least the pitch and For example, the tool support 18 is configured to adjust the pitch and roll simultaneously. 71-75, which are simultaneously moved in both the and roll degrees of freedom. The handle alignment projections relative to the tool plane BP and / or the tool alignment projections 916, 944 The placement of the angled portions 908, 938 of the projections 906, 936 is such that the projections 906, 936 are spaced apart in at least two degrees of freedom. provides a visual indication of the pose of the handheld portion 16 relative to the tool support. , respectively, relative to the tool plane BP and / or the tool alignment protrusions 916, 944 The second spatial arrangement 952 of the hand-aligned protrusions 906, 936 is At least a second pitch relationship 958 and a second roll relationship 97 of the tool support BP 0, providing a visual indication that the handheld portion 16 has an optimal range of motion for the tool support 18. provides a visual indication that the tool is in a pose relative to the tool support 18. Therefore, the operator must align the handle alignment protrusions 906, 936, the tool plane BP, and / or or so that the tool alignment protrusions 916, 944 are aligned in a first spatial relationship 944. The operator must adjust the pose of the handheld portion 16. and provides maximum adjustability for the instrument 14.
[0197] As an example of this feedback in multiple degrees of freedom, Figures 71-75 show the steering One end of the alignment protrusions 906, 936 is aligned with the longitudinal axis 910 in the pitch direction. Along the other end of the tool plane BP and / or the tool alignment protrusions 916, 944 and one side of the handle alignment protrusions 906, 936 is further away from the roll direction. the tool plane BP and / or the other side of the handle alignment protrusion 906, 936. 9B, or is further moved away from tool alignment protrusions 916, 944. Thus, the handle alignment protrusions 906, 936 (and in some configurations the tool The diagonal placement of the alignment protrusions 916, 944 provides a visual indication of the roll degree of freedom. A first visual reference is directed toward the outer portion 972 of the handle alignment protrusion 906, 936. A first portion of the handle alignment protrusions 906, 936 provides a visual indication of the degree of freedom of the handle. By providing a second visual reference towards minute 960, the handheld portion 16 This facilitates visual indication of the pose of the tool support 18 relative to the The portions 908, 938 and the handle alignment protrusions 906, 936 are handle alignment protrusions. provides increased functionality for visual indication compared to an orthogonal array of.
