Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a DBS electrode implantation adapter, a component and a robot system. Background Art

[0002] Deep Brain Stimulation (abbreviated as DBS) is a minimally invasive neurosurgical method that uses stereotactic technology to implant stimulating electrodes at specific target points in the brain for electrical stimulation, so as to regulate the excitability of corresponding nuclei to achieve the therapeutic purpose. It can be used to treat movement disorders, such as Parkinson's disease, essential tremor, dystonia, etc.

[0003] The implantation direction and depth of the electrode are the key to the surgery. At present, there are two ways to assist the implantation of DBS electrodes:

[0004] Method 1: Install a stereotactic head frame on the patient's head, collect medical images of the patient's head and the head frame for patient registration, then adjust the orientation bow so that the guiding channel reaches the electrode implantation direction, and calculate the depth based on the head frame coordinate system, and manually adjust the depth of the electrode. The defect of this method is that it is necessary to drill holes in the head to install a heavy head frame and collect medical images, the operation process is cumbersome, and the accuracy of manually adjusting the orientation bow and the electrode depth is low.

[0005] Method 2: Use a surgical robot to guide the electrode implantation. After the patient registration is completed, the surgical robot controls the guiding channel to reach the electrode implantation direction to guide the electrode, and then manually adjusts the implantation depth of the electrode. At present, the robot-guided electrode implantation can only provide guidance for the electrode implantation direction, and cannot accurately adjust the implantation depth of the electrode, and the angle accuracy has not reached the ideal standard.

Obviously, the drawings in the following description are some embodiments of the present invention.

[0042] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention with reference to the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention fall within the scope of protection of the present invention.

[0043] The following will describe the DBS electrode implantation adapter, assembly, and robotic system of the present invention in conjunction with Figures 1 - 5 description.

[0044] Figure 1 is one of the structural schematic diagrams of the DBS electrode implantation adapter provided by the present invention, as shown in Figure 1As shown in the figure, the DBS electrode implantation adapter includes: a main body 11, an embedding part 12, and a mounting part 13 provided on the main body 11. The embedding part 12 is embedded in the guiding channel of the robotic arm adapter flange during use. The guiding channel provided by the robotic arm adapter flange can provide positioning guidance for various surgical operations such as skull drilling, bone nail implantation, electrode implantation, puncture needle implantation, biopsy needle implantation, etc. The guiding channel here is just a general channel, and an adapter needs to be installed in the guiding channel to adapt to operating tools of different diameters. The adapter of this solution is precisely positioned by installing it into the guiding channel through the embedding part 12.

[0045] The DBS electrode implantation adapter (hereinafter referred to as the adapter) is also provided with a guiding hole 14 penetrating through the main body 11 and the embedding part 12, which is used to provide a channel for the directional setting of the trocar. Since the electrode material is relatively soft, directly passing the electrode through the guiding hole 14 to guide the electrode implantation may cause the electrode to bend in the brain tissue, resulting in the deviation of the electrode discharge end from the target point. Therefore, the trocar is used to perform tissue puncture under the guidance of the guiding hole 14, and the trocar provides an accurate and stable (extracranial and intracranial) electrode channel.

[0046] The adapter is also provided with a mounting part 13, and the mounting part 13 is adapted to the mounting structure of the stepper, which facilitates the accurate and stable mounting of the stepper to the adapter. The stepper is a precise displacement control device. After the electrode penetrates into the trocar, by connecting the rear end (non-implantation end) of the electrode through the stepper, the implantation depth of the electrode can be accurately controlled. It can be understood that Figure 1 only the state where the mounting part 13 is provided on the top of the main body 11 is shown, and the position of the mounting part 13 on the main body 11 can be flexibly adjusted. For example, it can also be provided at the bottom, side, etc. of the main body 11, as long as the mounting part 13 is adapted to the stepper, which is convenient for the stepper to control the implantation depth of the electrode.

[0047] Generally, the adapter flange at the end of the robotic arm is a standard part, and the guiding channel of the adapter flange is relatively small (for example, 1 - 4 cm), and the nearby space position is relatively limited. The adapter is only used to be installed into the guiding channel to provide a specific diameter of the hole for the corresponding medical instruments to pass through (for example, for the drill bit, electrode to pass through). By designing a special adapter, the present invention expands the installation range by using the main body 11 connecting the embedding part and the mounting part 13 on the main body 11. The adapter can not only guide the implantation direction of the electrode, but also install the stepper to accurately control the implantation depth of the electrode; moreover, the main body 11, the embedding part 12, and the mounting part 13 are integral parts, and the stepper and the robotic arm adapter flange are connected through only one part (the adapter), reducing the additional errors introduced by the cooperation between multiple parts, with a smaller radial position deviation of the electrode and improving the angular accuracy of the implanted electrode.

[0048] Based on any one of the embodiments, the embedding part 12 is provided with at least one locking hole 121, which is used for, after the embedding part is embedded into the guiding channel, a fastener passing through a clamping hole provided on the side wall of the guiding channel to reach the locking hole 121, so as to fix the relative position of the embedding part 12 and the adapter flange.

[0049] Specifically, still referring to Figure 1 , the embedding part 12 is provided with at least one locking hole 121, and the side wall of the guiding channel of the adapter flange is provided with a clamping hole corresponding to the locking hole 121. After the embedding part 12 is installed into the guiding channel of the adapter flange, a fastener passes through the clamping hole to reach the locking hole 121, so as to fix the relative position of the embedding part 12 and the adapter flange. The locking hole 121 can be a through hole, a blind hole or a threaded hole, and the clamping hole on the adapter flange can be a through hole or a threaded hole. It can be understood that when the locking hole 12 or the clamping hole has a thread, the fastener needs to be provided with a matching threaded section.

[0050] Referring to Figures 1 - 2 , based on any one of the embodiments, the main body 11 is provided with at least one threaded hole 111 communicating with the guiding hole 14, and the number can be one, two or more. The threaded hole 111 can be used in cooperation with a screw 112. When the screw 112 is installed into the threaded hole 111, it can apply pressure to the electrode sleeve, so as to fix the relative position of the trocar and the guiding hole 14, so as to provide a stable deep brain electrode implantation channel through the trocar and ensure the accuracy of electrode implantation.

[0051] Still referring to Figure 2 , based on the previous embodiment, the axial direction of the threaded hole 111 provided on the main body 11 is perpendicular to the axial direction of the guiding hole 14, so that the screw 112 can provide a positive pressure for the trocar, improve the locking effect and prevent the trocar from sliding in the guiding hole 14.

[0052] Still referring to Figure 2 , based on the previous embodiment, the main body 11 is provided with two threaded holes 111, and the axial directions of the two threaded holes 111 are perpendicular to each other, that is to say, the axial directions of the two threaded holes 111 and the axial direction of the guiding hole 14 are perpendicular to each other in pairs. This structure can further improve the fastening effect of the screw 112 on the trocar.

[0053] Referring to Figure 3 , based on any one of the above embodiments, the main body 11 is provided with a weight-reducing hole or a weight-reducing groove 15 to reduce the weight of the adapter and the load of the robotic arm, thereby improving the accuracy of electrode implantation. The position of the weight-reducing hole or the weight-reducing groove 15 can be set flexibly. For example, it can be set at the bottom of the main body 11, or for another example, it can be set on the side of the main body 11. The size of the weight-reducing hole or the weight-reducing groove 15 can be set flexibly. For example, the size can be adjusted so that the weight-reducing ratio reaches 10%, 15%, 20%, 30% and so on.

[0054] Based on any one of the embodiments, the adapter is made of a light alloy material, such as aluminum alloy, magnesium alloy, titanium alloy, etc. The light alloy can reduce the load of the robotic arm while meeting the mechanical strength requirements. Further, the adapter preferably uses aluminum alloy material, which is easy to process and has a low material cost, capable of reducing the overall cost of the product.

[0055] Still referring to Figures 1 - 2 , based on any one of the embodiments, the mounting portion 13 includes at least two mounting structures provided on the main body 11. The at least two mounting structures can improve the positioning accuracy and mounting stability of the stepper, prevent the stepper from rotating and shifting, and ensure the electrode implantation accuracy. Additionally, in the mounted state, the stepper is also connected to the rear end of the electrode to control the implantation depth of the electrode. The direction in which the stepper drives the electrode to move needs to be the same as the direction of the guiding hole 14, thereby avoiding electrode bending and improving the control accuracy of the electrode implantation depth.

[0056] Based on any one of the embodiments, the mounting structure on the main body 11 can be a fixed pin, and the stepper is provided with a mating pin hole. The two are installed by pin fitting. Of course, the mounting structure on the main body 11 can also be a pin hole, and the stepper is provided with a mating fixed pin for fitting installation; the mounting structure on the main body 11 can also be a stud, and the stepper is provided with a corresponding through hole. After the stud passes through the through hole, it is locked with a nut / nut; the mounting structure on the main body 11 can also be a threaded hole, and the stepper is provided with a corresponding through hole. After a screw / bolt passes through the through hole, it is locked with the threaded hole; the mounting structure provided on the main body 11 can also be a card slot, and the stepper is provided with a corresponding clamping structure for clamping and fitting installation.

[0057] This embodiment provides various forms of mounting structures, enabling the stepper to be quickly and accurately mounted on the adapter.

[0058] The present invention also provides a DBS electrode implantation guiding assembly. The DBS electrode implantation guiding assembly described below can be understood by referring to the DBS electrode implantation adapter described above.

[0059] Referring to Figure 4, a DBS electrode implantation guiding assembly provided by the present invention includes: a transfer flange 200, any one of the aforementioned DBS electrode implantation adapters 100, a trocar, and a stepper. The transfer flange 200 is connected to the end of the robotic arm 300, and a guiding channel 21 is provided on the transfer flange 200. After patient registration is completed, the surgical robot controls the movement of the robotic arm 300 to the target position according to the planned implantation path, so that the guiding channel 21 is in the implantation direction of the electrode. The adapter 100 is installed in the guiding channel 21 through the embedding portion 12. The diameter of the guiding hole 14 of the adapter is adapted to the outer diameter of the trocar, and provides directional guidance for the trocar in the installed state. The trocar includes an outer tube and an inner core. After the trocar punctures close to or reaches the target under the guidance of the guiding hole 14, the inner core is withdrawn, and the DBS electrode is inserted into the outer tube. The trocar provides a guiding channel for the DBS electrode outside and inside the skull, avoiding the risks of electrode bending and the discharge end deviating from the target caused by directly puncturing with the electrode. The installation portion 13 of the adapter 100 is also used to adapt and install the stepper. The stepper is connected to the rear end of the electrode. The stepper is a precise displacement control device for controlling the implantation depth of the electrode. It can be understood that the direction in which the stepper guides and drives the movement of the electrode is the same as the direction of the guiding hole 14, avoiding electrode bending and affecting the control accuracy of electrode implantation.

[0060] Based on any embodiment, the guiding channel 21 is a columnar through-hole, which can cooperate with the embedding portion 12 for quick installation. Preferably, the guiding channel 21 is a non-cylindrical columnar through-hole. The non-cylindrical columnar through-hole can prevent the embedding portion 12 from rotating in the guiding channel 21, so that the adapter 100 can be stably installed in the guiding channel at a fixed angle without repeatedly correcting the installation direction of the adapter.

[0061] Refer to Figure 5 , based on any embodiment, the DBS electrode implantation guiding assembly further includes at least two first fasteners 22, and the first fasteners 22 are used to connect the transfer flange 200 to the end of the robotic arm 300. At least two first fasteners 22 can improve the installation positioning accuracy, improve the installation stability, and prevent the transfer flange from rotating and moving.

[0062] Still refer to Figure 5 , based on any embodiment, it further includes at least one second fastener 212. A clamping hole 211 is provided on the side wall of the guiding channel 21. The second fastener 212 is used to fix the DBS electrode implantation adapter 100 through the clamping hole 211 after the DBS electrode implantation adapter 100 and the guiding channel 21 are combined as expected.

[0063] Specifically, the second fastener 212 can pass through the clamping hole 211 and directly abut against the embedding portion 12 to squeeze and fix it in the guiding channel 21. Further refer toFigure 1 Moreover, the embedding part 12 of the DBS electrode implantation adapter 100 may be provided with a locking hole 121. The second fastener 212 passes through the clamping hole 211 on the side wall of the guiding channel 21 and cooperates with the locking hole 121 to fix the embedding part 12. Further, at least one of the clamping hole 211 and the locking hole 121 is a threaded hole for cooperating with the second fastener 211 to improve the fastening effect.

[0064] In this embodiment, the position of the adapter is locked by the second fastener 212, preventing the adapter from loosening and ensuring the accuracy of DBS electrode implantation.

[0065] Based on any of the embodiments, in one embodiment, the guiding hole 14 is in clearance fit with the trocar, facilitating the smooth passage of the trocar through the guiding hole 14 to construct an electrode implantation channel (extracranial + intracranial channel). Preferably, the positive error of the inner diameter of the guiding hole does not exceed 2%, and the negative error of the outer diameter of the trocar does not exceed 1%. For example, the inner diameter of the guiding hole is designed to be 1.80 - 1.82 mm, and the outer diameter of the trocar is designed to be 1.79 - 1.80 mm.

[0066] The present invention also provides a DBS electrode implantation robot system. The DBS electrode implantation robot system described below can be understood with reference to the DBS electrode implantation adapter and the DBS electrode implantation guiding assembly described above.

[0067] The DBS electrode implantation robot system provided by the present invention includes: a host, a robotic arm, an input / output device, and the DBS electrode implantation guiding assembly according to any of the foregoing items.

[0068] Specifically, a processor and a memory are provided in the host for performing patient registration operations and navigation and positioning operations of the robotic arm, and controlling the robotic arm to reach the target position. In the target pose of the robotic arm, a DBS electrode implantation adapter can be installed on the end flange of the robotic arm. The implantation direction of the implanted electrode is guided by the DBS electrode implantation adapter, and then the implantation depth of the electrode is accurately controlled by the stepper installed on the adapter, so that the discharge end of the electrode accurately reaches the target point. The robot system also includes an input / output device. The input device such as a keyboard, a mouse, a foot switch, etc. is used for inputting control commands, inputting and collecting data, etc. The output device such as a display, an audio player, etc. is used for displaying or playing surgical-related information, facilitating the user to observe and understand the current surgical state.

[0069] The DBS electrode implantation robot system of the present invention controls the manipulator to move to the target position, positions the adapter in the electrode implantation direction through the flange at the end of the manipulator, and by designing a dedicated adapter, expands the installation range by using the main body connecting the embedding part and the installation part on the main body. The adapter can not only guide the implantation direction of the electrode, but also install a stepper to precisely control the implantation depth of the electrode. Moreover, the main body, the embedding part, and the installation part are integral parts, and the stepper is connected to the manipulator transfer flange through only one part (the adapter), reducing the additional errors introduced by the cooperation between multiple parts, making the radial position deviation of the electrode smaller, and improving the angular accuracy of the implanted electrode.

[0070] Based on the previous embodiment, the end of the manipulator is connected to the DBS electrode implantation guiding assembly through a transfer flange. Specifically, the adapter is installed into the guiding channel of the transfer flange through the embedding part, and the direction of the trocar (i.e., the implantation direction of the electrode) is guided through the guiding hole. The adapter is also provided with an installation part for installing a stepper to control the implantation depth of the electrode. The computer program is stored in the memory, and the processor can load and execute the computer program stored in the memory to control the end of the manipulator to reach the target position and guide the implantation direction of the electrode.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. However, such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
