Description

Technical Field

[0001] This utility model relates to the field of robot-assisted dental implant technology, and in particular to a stop-drill measurement tool. Background Technology

[0002] In robot-assisted dental implant surgery, precise control of drilling depth is crucial. To ensure surgical safety and prevent the end effector from exceeding the predetermined depth and causing injury to the patient, current surgical robot systems are equipped with a key safety protection mechanism: once the drilling depth reaches the preset planned value, the surgical robot automatically cuts off the power to the drill, stopping its operation and thus ensuring patient safety.

[0003] In existing technologies, surgical robot systems include a trolley, an implant handpiece, and an implantation unit. The trolley contains relays, and the cables connecting the implantation unit and the implant handpiece are connected to the trolley. The relays within the trolley control the continuity and connection of these cables. Under normal circumstances, the relays supply power to the cables, allowing the implant handpiece to operate normally and drill. When a protective measure is needed, the relays inside the trolley disconnect the cables, preventing the implantation unit from supplying power to the implant handpiece, and causing the implant handpiece's drill to stop working. Due to unavoidable errors in the control and detection process, the timing of the drill's power system cutoff may deviate. This deviation can lead to two serious consequences: First, if the relay cuts off power prematurely, the drill stops rotating before reaching the planned depth, preventing the implant from reaching the designed insertion depth and severely impacting the success rate and outcome of the surgery. Second, if the relay cuts off power too late, the power system's travel exceeds the planned depth without timely disconnection, resulting in excessively deep implantation and posing significant risks and harm to the patient.

[0004] Therefore, there is an urgent need for a drilling stop measurement tool to solve the above-mentioned problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a drilling stop measurement fixture, which significantly improves the accuracy and efficiency of measurement, greatly enhances the convenience and flexibility of the testing operation, and is simple to operate, providing a more complete and efficient solution for the performance testing of the drilling stop protection function of the surgical robot-assisted dental implant system.

[0011] The signal processing unit is electrically connected to the relay inside the trolley and the linear distance measuring sensor.

[0012] As a preferred technical solution for a drilling stop measurement fixture, the drilling stop measurement fixture further includes a calibration needle.

[0025] This invention provides a drilling stop measurement fixture. During testing, only the disconnection of a relay inside the trolley is needed to indicate whether the drill bit is de-energized. First, a calibration finger is installed at the end of the robotic arm. The calibration finger primarily simulates surgical tools used in implantation. Using the calibration finger during measurement effectively prevents damage to the actual surgical tools, thus reducing costs. Then, the relay disconnects when the calibration plane moves downwards a preset distance. Next, the robotic arm drives the calibration plane to descend at a constant speed, simulating the drilling process. When the calibration plane reaches the preset distance, the relay disconnects again. Simultaneously, the signal processing unit acquires the actual distance of the calibration plane detected by the linear distance measuring sensor at the instant the relay disconnects. This actual distance simulates the actual distance the drill bit moves.

[0041] Example 1

[0042] like Figure 1 and Figure 2As shown, this embodiment provides a drilling stop measurement fixture, which includes a linear distance sensor 1, a sensor base 2, a calibration finger 3, and a signal processing unit 10. The linear distance sensor 1 is mounted on the sensor base 2. The calibration finger 3 is mounted on the end of the robotic arm 100 and has a calibration plane 31. The detection path of the linear distance sensor 1 is perpendicular to the calibration plane 31, and the robotic arm 100 can drive the calibration finger 3 to move in a direction perpendicular to the calibration plane 31. The signal processing unit 10 is electrically connected to a relay 9 inside the trolley 8 and the linear distance sensor 1. The signal processing unit 10 can identify the power-off signal of the relay 9 and obtain the detection result of the linear distance sensor 1. The drilling stop measurement fixture is used to detect the accuracy of the robotic arm 100. During detection, it is only necessary to detect whether the relay 9 inside the trolley 8 is disconnected to indicate whether the drill bit is de-energized. To test the accuracy of the robotic arm 100, a calibration finger 3 is first installed at the end of the robotic arm 100 during the test. The main function of the calibration finger 3 is to simulate implantation surgical tools. During the measurement process, the use of the calibration finger 3 can effectively prevent damage to the real surgical tools, thereby reducing costs. Then, when the calibration plane 31 moves downward a preset distance, the relay 9 disconnects; then, the robotic arm 100 drives the calibration plane 31 to descend at a constant speed, simulating the process of drilling downwards; when the calibration plane 31 moves to the preset distance, the relay 9 disconnects, and at the same time, the signal processing unit 10 acquires the actual distance of the calibration plane 31 detected by the linear ranging sensor 1 at the moment the relay 9 disconnects. The actual distance moved by the calibration plane 31 simulates the actual distance moved by the drill bit; the robotic arm 100 moves a preset distance in a direction perpendicular to the calibration plane 31, and the linear ranging sensor 1 detects the actual distance moved by the calibration plane 31. The actual distance moved by the calibration plane 31 simulates the actual distance moved by the drill bit. The preset distance is compared with the actual distance to determine the disconnection accuracy of the relay 9, whether the disconnection of the relay 9 in the surgical robot system is delayed or premature. When the relay 9 disconnects delayed, the actual distance is greater than the preset distance; when the relay 9 disconnects prematurely, the actual distance is less than the preset distance. The movement accuracy of the robotic arm 100 is then assessed to determine whether the robotic arm 100 meets the requirements. The linear ranging sensor 1 of this invention simplifies the operation process of aligning the sensor's measurement direction with the detection plane 31, significantly improving the accuracy and efficiency of measurement, greatly enhancing the convenience and flexibility of the detection operation, and providing a more complete and efficient solution for the performance testing of the stop-drill protection function of the surgical robot-assisted dental implant system.

[0043] Preferably, the stop-drill measurement fixture further includes a calibration bur 4. The first end of the calibration finger 3 is connected to the end of the robotic arm 100, and the second end of the calibration finger 3 is connected to the calibration bur 4. The sensor base 2 is provided with a calibration hole 21, the outer diameter of which is the same as the inner diameter of the calibration bur 4. The robotic arm 100 can drive the calibration bur 4 into the calibration hole 21. Before detection, the robotic arm 100 first drives the calibration bur 4 into the calibration hole 21 to define the relative position of the robotic arm 100 and the linear ranging sensor 1, and to define the direction of movement of the calibration finger 3 driven by the robotic arm 100. This further ensures the accuracy and reliability of the measurement, providing accurate data support for surgical navigation and related operations.

[0044] It should be noted that the calibration hole 21 is a relatively deep cylindrical hole, the diameter of which is equal to the diameter of the end of the calibration needle 4 on the calibration finger 3, and the two are precisely clearance-fitted. The direction of the path hole is consistent with the measurement direction of the linear ranging sensor 1. In mechanical navigation, inserting the calibration needle 4 of the calibration finger 3 into the calibration hole 21 can obtain a reasonable target position and attitude, ensuring that the measurement path is precisely aligned with the drilling direction and improving measurement accuracy.

[0045] In this embodiment, the second end of the calibration finger 3 is provided with a mounting hole, and the inner wall of the mounting hole is provided with a threaded hole. A set screw is threaded into the threaded hole and abuts against the side wall of the calibration needle 4, thereby realizing the detachable connection of the calibration needle 4 to the second end of the calibration finger 3. In other embodiments, the calibration finger 3 and the calibration needle 4 can also be integrally formed.

[0046] Preferably, the extension direction of the calibration hole 21 is parallel to the extension direction of the detection path of the linear distance measuring sensor 1; the calibration needle 4 is perpendicular to the calibration plane 31, which simplifies the relative position of the calibration needle 4 and the calibration plane 31, simplifies the relative position of the linear distance measuring sensor 1 and the calibration hole 21, facilitates the path planning and navigation of the robotic arm 100, and improves the measurement accuracy.

[0047] Furthermore, such as Figure 3 As shown, in this embodiment, the signal processing unit 10 is a microcontroller. The microcontroller can obtain the power-off state of the relay 9. The linear ranging sensor 1 is responsible for real-time monitoring of the position information of the calibrated finger 3 and transmitting it to the microcontroller for processing. When the robotic arm 100 drives the calibrated finger 3 to move a preset distance, the relay 9 is powered off and sends a signal to the microcontroller. The microcontroller obtains the detection information from the linear ranging sensor 1 to get the actual distance, compares the preset distance with the actual distance, and judges the power-off accuracy of the relay 9.

[0048] Preferably, the microcontroller is equipped with a digital display 101, which is used to display the measurement information of the linear distance measuring sensor 1. In this embodiment, the value displayed on the digital display 101 is the actual distance minus a preset distance, so that the operator can intuitively obtain the movement error of the robotic arm 100.

[0049] It should be noted that relays 9 inside the trolley 8 are connected to the microcontroller's digital input / output port and high-level interface, respectively. When the robotic arm 100 is operating normally, relay 9 is not disconnected, and the digital input / output port is at a high level. When relay 9 is disconnected, the digital input / output port level changes to a low level. This level change serves as an important signal for subsequent logic judgments and operations by the microcontroller. By writing a specific program, the digital display 101 can output the reading of the linear distance sensor 1 in real time. Simultaneously, a dedicated program is written inside the microcontroller; when the digital input / output port level changes from high to low, the digital display 101 will maintain the reading at the moment of level change, thus recording the drill bit's position information at the instant drilling stops. Furthermore, for ease of operation, several operation buttons can be connected to the microcontroller to perform common operations such as reset and zeroing, improving the ease of use of the tooling.

[0050] It should be noted that this embodiment also provides a measurement method for the drilling stop measurement fixture, including the following steps:

[0051] Step 1: First, obtain the relative positions of the linear ranging sensor 1, sensor base 2, calibration finger 3, and robotic arm 100;

[0052] Step 2: Plan the position and posture of the robotic arm 100 end effector to the target position and posture in the surgical navigation system. Under the target position and posture, the linear ranging sensor 1 should be able to measure the calibration plane 31 of the calibration finger 3 in real time.

[0053] Step 3: After the robotic arm 100 reaches the target position and attitude, record the initial value of the linear ranging sensor 1;

[0054] Step 4: When the calibration plane 31 moves downward by a preset distance, the relay 9 disconnects;

[0055] Step 5: The robotic arm 100 drives the calibration plane 31 to descend at a constant speed, simulating the process of drilling downwards; when the calibration plane 31 moves to the preset distance, the relay 9 is disconnected, and at the same time, the microcontroller acquires the actual distance detected by the linear distance measuring sensor 1 at the moment the relay 9 is disconnected.

[0056] Step 5: Subtract the preset distance from the actual distance to obtain the error value, calculate the drilling stop protection error, and determine whether the drilling stop position is before reaching the boundary or after exceeding the boundary by using the sign of the error value; and determine whether the magnitude of the error value meets the operating requirements by using the magnitude of the error value.

[0057] This embodiment indirectly determines the disconnection accuracy of relay 9 by the magnitude of the error value, and whether the disconnection of relay 9 in the surgical robot system is delayed or premature.

[0058] Firstly, this drilling stop measurement fixture can accurately measure the position of the drill bit near the drilling depth by using a linear distance sensor 1 to detect the position of the drill bit in real time and input a stop signal. It can directly and accurately measure the position of the drill bit when drilling stops, effectively solving the problem that similar devices cannot detect when the drill bit stops before reaching the specified depth, thus improving the comprehensiveness and accuracy of the measurement. Secondly, this drilling stop measurement fixture is easy to operate: the microcontroller can not only output the reading of the linear distance sensor 1 in real time, but also lock key data when the level of the relay 9 changes. It can also be equipped with operation buttons to facilitate users to perform operations such as reset and zeroing, greatly simplifying the operation process, enhancing the user experience, and making data acquisition and fixture adjustment more efficient.

[0059] Example 2

[0060] This embodiment also provides a drilling stop measurement fixture, which provides another method for defining the relative position of the robotic arm 100 and the linear distance sensor 1, as well as a method for defining the movement direction of the robotic arm 100 driving the calibration finger 3.

[0061] In this embodiment, as Figure 1 and Figure 2 As shown, the drilling stop measurement fixture also includes a probe 5 and an optical positioning system. Multiple registration points 22 are set on the sensor base 2, and the probe 5 is used to identify the registration points 22. A navigation marker 6 is set on the sensor base 2, and the optical positioning system is used to identify the navigation marker 6. This embodiment provides a second method for identifying the position of the linear ranging sensor 1. The probe 5 identifies the registration points 22, and the optical positioning system identifies the navigation marker 6, thereby defining the relative position of the robotic arm 100 and the linear ranging sensor 1, as well as defining the direction of movement of the robotic arm 100 driving the calibration finger 3. In this embodiment, the navigation marker 6 can be an optical or magnetic navigation marker. The optical positioning system's identification of the navigation marker 6 is existing technology and will not be elaborated upon here.

[0062] Specifically, the registration point 22 is a dot matrix composed of multiple circular holes, and the relative position of the dot matrix and the linear ranging sensor 1 is ensured by machining precision. During optical navigation operation, after installing the navigation marker 6, the operator can use the probe 5 to click on each registration point 22 to obtain the relative position of the navigation marker 6 and the registration point 22, and then calculate the relative position of the linear ranging sensor 1 relative to the navigation marker 6, providing accurate data support for surgical navigation path planning.

[0063] Preferably, multiple registration points 22 are located in a first plane, and the detection path of the linear ranging sensor 1 is perpendicular to the first plane; multiple navigation markers 6 are located in a second plane, which is perpendicular to the first plane. After identifying the navigation markers 6 and the registration points 22, the 3D positions of the sensor base 2 and the linear ranging sensor 1 can be accurately obtained.

[0064] Preferably, the second plane and the linear ranging sensor 1 are offset along a direction perpendicular to the second plane. When the optical positioning system identifies the navigation marker 6, the linear ranging sensor 1 and the navigation marker 6 are no longer on the same plane, preventing the linear ranging sensor 1 from interfering with the identification of the navigation marker 6 and improving detection efficiency.

[0065] In this embodiment, the sensor base 2 is provided with a connecting part. The connecting part is Z-shaped in the view along the direction perpendicular to the first plane. The Z-shape includes two parallel side walls. The linear ranging sensor 1 and the navigation marker 6 are respectively installed on the two parallel side walls so that the second plane and the linear ranging sensor 1 are misaligned in the direction perpendicular to the second plane.

[0066] In this embodiment, the drilling stop measurement fixture also includes a mounting base 7, which is cross-shaped and connected to the side wall of the sensor base 2. Navigation markers 6 are installed at the four ends of the mounting base 7. Specifically, the sensor base 2 is provided with threaded holes for connecting the mounting base 7, which serve as mechanical interfaces. The mounting base 7 is provided with through holes, through which screws are threaded and connected to the threaded holes, thereby fixing the mounting base 7 to the side wall of the sensor base 2.

[0067] This drilling stop measurement fixture is highly adaptable. The sensor base 2 is equipped with a mechanical interface that is fixedly connected to the surgical tracking device. It can be adapted to various surgical tracking devices such as optical, magnetic navigation markers or the end of mechanical navigation devices, which facilitates path planning and navigation in surgical navigation and improves the versatility and applicability of the fixture.
