Description

Technical Field

[0001] The present invention relates to a wireless fracture reduction robot device and its operation system. More specifically, it relates to a wireless fracture reduction robot device that checks and controls the operation of a fracture reduction robot from which wires that may interfere with the movement line of a surgeon during a fracture operation have been removed, and to this operation system.

Background Art

[0002] Minimally invasive fracture reduction surgery is a fracture reduction surgery that minimizes incisions on a patient. In such a fracture reduction surgery, correction is performed to return a displaced bone to its original position using real-time X-ray imaging equipment such as a C-ARM, and the corrected bone fragments are fixed by inserting a metal nail into the intramedullary cavity in the corrected state.

[0003] During such a fracture reduction surgery process, a real-time X-ray image is acquired with the patient's fractured part positioned between the X-ray source and the two-dimensional sensor of the C-ARM, and the doctor proceeds with the fracture reduction surgery while viewing such a real-time X-ray image.

[0004] In particular, since the fractured part of the bone is located deep inside from the skin, it is difficult to visually confirm the fracture state of the bone, the reduction process, the alignment state accompanying the reduction, etc., so it is common to proceed with the fracture reduction surgery with the assistance of real-time X-ray imaging equipment such as a C-ARM.

[0005] However, X-ray imaging equipment such as a C-ARM may require continuous irradiation of X-rays to obtain a real-time image, so the radiation exposure to patients and the medical team, etc. is tending to increase compared to other X-ray equipment that obtains a still image.

[0006] In particular, for a medical team that repeatedly performs fracture reduction surgery, the risk of exposure to radiation is a major problem.

[0007] In addition, since various muscles are connected to the bone, a large force is required to reduce a fractured bone, and thus, it is common for multiple medical teams to cooperate with each other to perform the surgery.

[0008] There is a problem that a large number of medical teams are required to perform a fracture reduction surgery, which acts as a factor increasing the surgical cost and the like.

[0009] In addition, after the misaligned bone is corrected by the human power of the medical team, it is never easy to accurately maintain the corrected state until the corrected state is fixed by inserting a metal nail into the intramedullary cavity or the like. For such reasons, there is a problem that inaccurate fracture reduction may coexist.

[0027] Here, detailed descriptions of well-known functions and configurations that are repeatedly described and may obscure the gist of the present invention are omitted. Embodiments of the present invention are provided to more fully explain the present invention to those of average skill in the art.

[0028] Hereinafter, a detailed description will be given based on FIGS. 1 to 9 for explaining embodiments of the present invention.

[0029] FIG. 1 is a block diagram showing the configuration of an operation system of a wireless fracture reduction robot according to an embodiment of the present invention.

[0030] Referring to FIG. 1, the operation system of the wireless fracture reduction robot according to an embodiment of the present invention may include a wireless fracture reduction robot device 1 and a user terminal 2.

[0031] The wireless fracture reduction robot device 1 includes a plurality of ring frames 110 provided to wrap around the fractured part of the patient, and at least one or more thrusts 120 provided between the plurality of ring frames 110 to adjust the separation distance between the ring frames 110. A control unit 400 is formed to measure the lengths of the one or more thrusts 120 and generate length information, and it is a device for reducing fractures of the affected part.

[0032] At this time, the ring frame 110 can be roughly classified into a distal ring frame 111 and a proximal ring frame 112 according to the position.

[0033] Such a wireless fracture reduction robot device 1 will be described in detail below.

[0034] The user terminal 2 is linked with the wireless fracture reduction robot device 1 to receive length information or the relative position / attitude between the distal ring frame 111 and the proximal ring frame 112, and can input operation information for adjusting the length of the thrust 120 from the user and transmit it to the wireless fracture reduction robot device 1.

[0035] Here, the user terminal 2 may be a terminal used by the user, such as a personal computer (PC), a mobile terminal, a tablet PC, a PDA (Personal Digital Assistant), etc.

[0036] Also, the operation information may be relative position / attitude information between the distal ring frame 111 and the proximal ring frame 112 or length information of the thrust 120.

[0037] Furthermore, the user terminal 2 may be linked with the wireless fracture reduction robot device 1 by utilizing a pairing method using a direct contact method such as NFC (Near Field Communication) and long-distance wireless communication using the 2.4GHz ISM general-purpose frequency.

[0038] Furthermore, the user terminal 2 can store the length information received from the wireless fracture reduction robot device 1 and analogize the overall shape of the wireless fracture reduction robot device 1 based on each length information and store it as shape information.

[0039] That is, the wireless fracture reduction robot device 1 can transmit to the user terminal 2 the relative position / orientation information or the length information of the thrust 120 between the distal ring frame 111 and the proximal ring frame 112 changed based on the operation information transferred from the user terminal 2.

[0040] Thereby, the user terminal 2 can accumulate data for suitable bone reduction using the length information, and provide the user with big data related to bone reduction according to patient characteristics.

[0041] FIG. 2 is a perspective view showing a wireless fracture reduction robot device according to an embodiment of the present invention, FIG. 3 is an exemplary view showing that FIG. 2 is worn on a human body, FIG. 4 is a control block diagram of FIG. 2, FIG. 5 is a perspective view showing that the motor module of the thrust and the wireless drive pack of FIG. 2 are connected, and FIG. 6 is a front view of FIG. 5.

[0042] The wireless fracture reduction robot device 1 according to an embodiment of the present invention may incorporate a battery, a motor module 210, etc. inside so that no electric wire is exposed outside, and wirelessly provide a patient's fracture reduction robot device. Referring to FIGS. 2 to 4, it may include a fracture reduction unit 100, a wireless drive pack 200, and a control unit 400.

[0043] The fracture reduction unit 100 may be a part that penetrates through a patient's arm or leg and is directly fixed to the affected part. The fracture reduction unit 100 can fix and traction the affected part to reduce the bone.

[0044] Here, reduction refers to an operation of returning a displaced bone fragment or a dislocated bone head, that is, a bone, to its original position in the case of a fracture or dislocation.

[0045] As shown in FIG. 2, the fracture reduction unit 100 may include a ring frame 110 and a thrust 120.

[0046] The ring frame 110 may be formed in the shape of a ring through which the patient's arm or leg passes, and may then be fixed according to the position of the affected part.

[0047] Also, a plurality of ring frames 110 may be provided, and the plurality of ring frames 110 may be positioned at a certain interval and fixed along the length direction of the fractured affected part.

[0048] Preferably, as shown in FIG. 3, the ring frames 110 are respectively fixed to the distal bone fragment DB and the proximal bone fragment PB, and can be roughly classified into a distal ring frame 111 and a proximal ring frame 112 according to the position.

[0049] The thrust 120 may be provided so as to connect the distal ring frame 111 and the proximal ring frame 112.

[0050] One or more such thrusts 120 are provided and formed to have a configuration in which the length is variable, such as an actuator or a cylinder, so that the angle and the separation distance between the distal ring frame 111 and the proximal ring frame 112 can be adjusted.

[0051] Specifically, referring to FIG. 5, the thrust 120 may include a cylinder 121, a rod 122, a lower end connector 123, and an upper end connector 124.

[0052] One end of the cylinder 121 is open, and a ring-shaped connector 121a is formed at the other end and may be connected to one ring frame 110 so as to be rotatable.

[0053] In addition, the cylinder 121 may be provided with a sight gauge 121b that allows the user to see through the inside along the circumferential length direction so that the user can grasp the position of the rod 122.

[0054] Furthermore, referring to FIG. 6, measurement scales may be formed along the length direction of 121b.

[0055] Therefore, the user can grasp the length of each thrust 120 through the sight gauge 121b, and can further grasp the shape of the fracture reduction unit 100 fixed to the affected part according to the length of the thrust 120.

[0056] The rod 122 may be arranged to move in one end direction along the length direction of the cylinder 121 inside the cylinder 121.

[0057] Also, one end of the rod 122 may be connected to the ring frame 110 by a lower end connector 124 described later and connected to the wireless drive pack 200 to reciprocate inside the cylinder 121.

[0058] The lower end connector 123 may be formed with a clamp (not shown) along the circumference so as to be in close contact with the periphery of the ring frame 110.

[0059] Furthermore, the lower end connector 123 can connect the rod 122 and the wireless drive pack 200 to transmit a driving force so that the rod 122 can reciprocate inside the cylinder 121.

[0060] The upper end connector 124 is connected so that the connecting body 121a can rotate, and can give six degrees of freedom in which the ring frame 110 can pitch, yaw, and roll according to the movement of the rod 122, that is, the change in the length of the thrust 120.

[0061] Therefore, the position and orientation between the distal ring frame 111 and the proximal ring frame 112 can be adjusted according to the change in the length of the thrust 120.

[0062] The wireless drive pack 200 may include a drive unit 210 connected to the ring frame 110 to transmit power for variable length to the thrust 120.

[0063] Specifically, the drive unit 210 has a motor module 211 built therein, and a driver coupler 212 that transmits the power of the motor module 211 protrudes in the direction of the thrust 120 and is connected to the lower end connector 123, so that power can be transmitted to the thrust 120.

[0064] Such a wireless drive pack 200 may be formed in a wireless form provided inside without exposing wires connected to the robot, such as communication lines and power lines, to the outside.

[0065] In addition, the wireless drive pack 200 is formed in a ring shape so that the patient's arm or leg can pass through it, and may have an inner diameter length longer than the outer diameter length of the ring frame 110.

[0066] In other words, the wireless drive pack 200 is formed to be larger than the ring frame 110, and when the patient's arm or leg passes through the ring frame 110, it can prevent the movement of the ring frame 110.

[0067] The sensor unit 300 can measure the position of at least one or more thrusts 120.

[0068] At this time, the sensor unit 300 may be provided at the thrust 120 of the fracture reduction unit 100, inside the wireless drive pack 200, etc. according to the user's request.

[0069] Such a sensor unit 300 will be described in more detail below.

[0070] The control unit 400 is provided inside the wireless drive pack 200 or the like, and can generate length information of the thrust 120 based on the position of the thrust 120 measured in the sensor unit 300.

[0071] Here, the control unit 400 can generate length information for each of at least one or more thrusts 120 that make up the fracture reduction unit 100.

[0072] In addition, the control unit 400 can have operation information for adjusting the length of the thrust 120 transferred from the user to the wireless drive pack 200 via the user terminal 2.

[0073] Here, the control unit 400 communicates with the user terminal 2 by utilizing a pairing method using a direct contact method such as NFC (Near Field Communication) and long-distance wireless communication using the 2.4 GHz ISM general-purpose frequency, and can also communicate with other terminals in addition to the user terminal 2.

[0074] Furthermore, the control unit 400 can provide the length information of the thrust 120 to the user terminal 2 so that the user can confirm it, and transfer the operation information for adjusting the length of the thrust 120 from the user terminal 2 to the wireless drive pack 200.

[0075] Therefore, based on the length information, the user can adjust the length of the thrust 120 to operate the shape of the fracture reduction unit 100 to suit the characteristics of the patient.

[0076] Such a control unit 400 can measure the lengths of one or more thrusts 120 that make up the fracture reduction unit 100, adjust the angle according to the change in length for each thrust 120, and provide information that can analogize the overall shape of the fracture reduction unit 100.

[0077] Furthermore, the user can construct big data related to bone restoration for each patient characteristic by estimating data for suitable bone restoration using the length information generated in the control unit 400.

[0078] The sensor unit 300 according to an embodiment of the present invention may include a rotation speed measurement sensor (not shown).

[0079] The rotation speed measurement sensor can measure the rotation speed of the motor module 211 and generate sensor information.

[0080] Here, the sensor information is the position of the thrust measured by the rotation speed measurement sensor using the rotation speed of the motor module 211.

[0081] Specifically, the rotation speed measurement sensor can be connected to the rotation axis of the motor module 211 or the rotation axis of the driver coupler 212 to measure the rotation speed by generating an electrical signal having one pulse per rotation in the rotation direction of the rotation axis.

[0082] Also, the rotation speed measurement sensor can further subdivide the rotation speed by dividing one rotation by 360 and measure it as the rotation angle, which can be set according to the user's request.

[0083] At this time, the control unit 400 can generate length information by determining the total length of the thrust 120 based on the sensor information transferred from the rotation speed measurement sensor as the motor module 211 rotates.

[0084] Specifically, the control unit 400 can generate length information of the thrust 120 based on the sensor information measured by the resistance measurement sensor 310, that is, the absolute value of the degree to which the rod 122 moves inside the cylinder 121 as the motor module 211 rotates.

[0085] On the one hand, the sensor unit 400 may be provided on the thrust 120. Hereinafter, various embodiments of the sensor unit 400 provided on the thrust 120 will be described.

[0086] FIG. 7 is an exemplary diagram showing that a sensor unit according to a first embodiment is formed on a thrust according to an embodiment of the present invention.

[0087] Referring to FIG. 7, the sensor unit 300 of the wireless fracture reduction robot device 1 according to an embodiment of the present invention can be replaced with a form according to a first embodiment.

[0088] At this time, a conductor 125 through which current flows along the longitudinal direction may be formed on the thrust 120.

[0089] The conductor 125 is formed along the longitudinal direction of the rod 122, but may be formed so as to be exposed through the site gauge 121b.

[0090] Such a conductor 125 has an increasing resistance as the number of collisions between electrons and atoms increases when the electrons pass through the conductor 125 as it moves away from the portion to which the current is applied, thereby hindering the flow of current.

[0091] The sensor unit 300 according to the first embodiment of the present invention may include a resistance measurement sensor 310.

[0092] The resistance measurement sensor 310 can measure the resistance via the magnitude of the current from the conductor 125 and generate sensor information.

[0093] Here, the sensor information is the position of the thrust measured using the magnitude of the resistance of the surface where the resistance measurement sensor 310 is in contact with the conductor 125.

[0094] Specifically, the resistance measurement sensor 310 is arranged adjacent to the site gauge 121b of the cylinder 121, but is formed so as to look in the direction of the site gauge 121b and can sense the current of the conductor 125.

[0095] Such a resistance measurement sensor 310 senses the current flowing through the conductor 125, but can measure the resistance according to the change in the strength of the current and generate sensor information using the resistance value.

[0096] That is, the position of the resistance measurement sensor 310 is fixed, and as the rod 122 moves, the position where it contacts the conductor 125 changes, so that the measured resistance value differs.

[0097] At this time, the control unit 400 can generate length information by being transferred sensor information that is a resistance value that differs according to the change in position accompanying the movement of the rod 122 and determining the total length of the thrust 120.

[0098] Specifically, the control unit 400 matches the sensor information measured by the resistance measurement sensor 310, that is, the resistance value measured so as to differ according to the degree of movement of the rod 122 inside the cylinder 121, and the total length formed by the thrust 120 at this time, and can generate the length information of the thrust 120.

[0099] FIG. 8 is an exemplary diagram showing that a sensor unit according to a second embodiment is formed on the thrust according to an embodiment of the present invention.

[0100] Referring to FIG. 8, the sensor unit 300 of the wireless fracture reduction robot device 1 according to the embodiment of the present invention can be replaced with the form according to the second embodiment.

[0101] At this time, the sensor unit 300 is arranged on the lower end connector 123, but one surface facing the other end of the rod 122 is open, and the wire 321 can be fed out or wound up as the rod 122 moves.

[0102] The sensor unit 300 according to the second embodiment of the present invention may include a winder 320, a wire 321, a spring (not shown), and a wire sensor 322.

[0103] The winder 320 can wind the wire 321 connected to the thrust 120.

[0104] At this time, the wire 321 is connected to a wire fixing protrusion extending from the other end of the rod 122 toward the site gauge 121b, and can be wound around the winder 320 or fed out from the winder 320 as the rod 122 moves.

[0105] The spring can rotate the winder 320 to feed out or wind the wire 321.

[0106] Specifically, when tension acts on the wire 321 connected to the rod 122 as the rod 122 is pulled out, the spring can rotate the winder 320 in the direction in which the tension acts to feed out the wire 321.

[0107] Also, the spring is formed in a shape in which an elastic body having elasticity is wound, and when the tension weakens as the wire 321 is pulled in by the rod 122, the spring can rotate the winder 320 in the opposite direction of the tension acting direction so that the wire 321 is wound, that is, returned to its original position.

[0108] In addition to this, when the wire 321 is wound or fed out, the spring can apply elasticity to the wire 321 so that the wire 321 does not slacken.

[0109] The wire sensor 323 can measure the length of the wire 321 fed out as the winder 320 rotates and generate sensor information.

[0110] Specifically, the wire sensor 322 is equipped with a potentiometer, and as the winder 320 rotates, a variable voltage or variable current is generated. Based on the resistance value corresponding to the variable voltage or variable current, the rotation speed is measured to determine the length of the wire 321, thereby generating sensor information.

[0111] In addition, the wire sensor 322 can recognize the rotation direction of the winder 320 and determine whether the wire 321 is being wound or unwound even when the same resistance value is measured.

[0112] At this time, the control unit 400 can be transferred the sensor information, which is the length of the wire 321 accompanying the movement of the rod 122, to determine the total length of the thrust 120 and generate length information.

[0113] Specifically, the control unit 400 matches the sensor information measured by the wire sensor 322, that is, the length of the wire 321 measured to be different according to the degree of movement of the rod 122 inside the cylinder 121, with the total length formed by the thrust 120 at this time, and can generate the length information of the thrust 120.

[0114] FIG. 9 is an exemplary diagram showing that a sensor unit according to a third embodiment is formed on the thrust according to an embodiment of the present invention.

[0115] Referring to FIG. 9, the sensor unit 300 of the wireless fracture reduction robot device 1 according to an embodiment of the present invention can be replaced with the form according to the third embodiment.

[0116] At this time, on the thrust 120, a reflector 126 whose reflector surface size becomes variable as it moves along the length direction may be formed.

[0117] The reflector 126 is formed to increase along the length direction of the rod 122, but may also be formed so as to be exposed through the site gauge 121b.

[0118] When light is incident on such a reflector 126, the area of the reflected light can increase along the length direction.

[0119] The sensor unit 300 according to the third embodiment of the present invention may include a light measurement sensor 330.

[0120] The light measurement sensor 330 can irradiate the reflector 126 with light, receive the light reflected from the reflector 126, and measure the reflection amount of the received light to generate sensor information.

[0121] Specifically, the light measurement sensor 330 is arranged adjacent to the site gauge 121b of the cylinder 121, but is formed so as to look in the direction of the site gauge 121b to irradiate the reflector 126 with light and receive the reflected light, thereby measuring the reflection amount of the reflected light and generating sensor information.

[0122] At this time, the control unit 400 can transfer sensor information regarding the reflection amount of light that varies according to the change in position accompanying the movement of the rod 122 and determine the total length of the thrust 120, thereby generating length information.

[0123] Specifically, the control unit 400 can match the sensor information measured by the light measurement sensor 330, that is, the reflection amount of light measured to vary according to the degree of movement of the rod 122 inside the cylinder 121, with the total length formed by the thrust 120 at this time to generate length information of the thrust 120.
