Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a deep electrode implantation auxiliary device. Background Technology

[0002] Deep brain stimulation (DBS) electrodes are implantable devices used for neuromodulation, primarily for the treatment of some neurological disorders.

[0003] Deep electrodes are usually flexible. To ensure that the deep electrode can be successfully implanted into the target site, it is usually fitted onto a mandrel made of a relatively hard material. After the deep electrode is implanted into the target site, the mandrel is then pulled out from the deep electrode.

[0004] However, the deep electrode implantation auxiliary devices provided by related technologies have difficulty ensuring that the deep electrode is reliably located at the target point after it has been implanted into the target point and during the process of removing the mandrel from the deep electrode. In other words, the deep electrode is prone to displacement as the mandrel is removed. Utility Model Content

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0039] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0040] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0041] Deep electrodes are typically flexible. To ensure successful implantation into the target site, they are usually fitted onto a rigid mandrel. After implantation, the mandrel is removed. However, the inventors discovered that friction between the mandrel and the deep electrode during removal can cause displacement of the deep electrode along with the mandrel, leading to its deviation from the target site.

[0042] To address the aforementioned issues, this embodiment provides a novel deep electrode implantation auxiliary device. This device ensures that the deep electrode remains reliably positioned at the target point after implantation and during the removal of the mandrel from the deep electrode, thus mitigating the problem of displacement after implantation and mandrel removal. Furthermore, it reliably guides the deep electrode during implantation and monitors its implantation depth in real time, thereby ensuring the accuracy of the implantation position and guaranteeing that the deep electrode is accurately implanted into the target point.

[0043] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The deep electrode implantation auxiliary device 010 of this embodiment includes a guide 100 and a clamping mechanism 200; the guide 100 is provided with a guide hole 101 for inserting the cannula needle 410; the clamping mechanism 200 includes a bracket 210 and a clamping assembly 220; wherein, the bracket 210 is connected to the guide 100; the clamping assembly 220 is slidably disposed on the bracket 210 and is used to clamp the deep electrode 420 so as to maintain the position of the deep electrode 420 when the core rod 430 inside the deep electrode 420 is withdrawn.

[0044] When implanting the deep electrode 420 using the deep electrode implantation auxiliary device 010, an outer cannula needle 410 can be inserted into the guide hole 101 of the guide 100. Then, the deep electrode 420 can be inserted into the outer cannula needle 410, and the deep electrode 420 can be slid relative to the outer cannula needle 410 to the position of the target point 030. Then, the deep electrode 420 is clamped by the clamping component 220, and the mandrel 430 inside the deep electrode 420 is pulled out. Since the deep electrode 420 is fixed by the clamping component 220 when the mandrel 430 is pulled out, the problem of the deep electrode 420 easily shifting when the mandrel 430 is pulled out can be improved, thus ensuring the accuracy of the deep electrode 420 implantation position at the target point 030.

[0045] It should be noted that the outer cannula needle 410 is not necessary. In some embodiments, the outer cannula needle 410 is not required, and the deep electrode 420 can be directly placed in the guide hole 101.

[0046] The structure of the guide 100 can be configured as needed; please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the guide 100 includes a guide body 110 and a first connecting portion 120 connected to the guide body 110. A guide hole 101 is disposed in the guide body 110 and passes through the first connecting portion 120. The bracket 210 includes a bracket body 211 and an assembly portion 212 connected to the bracket body 211. The assembly portion 212 is detachably connected to the first connecting portion 120. The clamping assembly 220 is slidably disposed on the bracket body 211. By configuring the bracket 210 to be detachably connected to the guide 100, the bracket 210 can be disassembled and assembled as needed. On the one hand, this facilitates the separation of the bracket 210 and the guide 100 for cleaning and disinfection. On the other hand, the bracket 210 can be removed when the cannula needle 410 is inserted into the guide hole 101 of the guide 100 to avoid the bracket 210 interfering with the assembly of the cannula needle 410.

[0047] Optionally, the mounting part 212 is detachably sleeved with the first connecting part 120. This ensures the ease of assembly and disassembly of the bracket 210, and also ensures the stability and reliability of the bracket 210 when assembled with the guide 100.

[0048] Alternatively, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The assembly part 212 is provided with a socket 213, and the first connecting part 120 is detachably sleeved with the socket 213. The wall of the socket 213 is provided with a first plane 214, and the peripheral wall of the first connecting part 120 is provided with a second plane 121. The first plane 214 and the second plane 121 are distributed opposite to each other to prevent the assembly part 212 and the first connecting part 120 from rotating relative to each other. By configuring the first plane 214 and the second plane 121, the stability of the bracket 210 assembled with the guide 100 can be improved, and the problem of the bracket 210 easily rotating accidentally relative to the guide 100, which would be inconvenient for the implantation operation of the deep electrode 420, can be improved.

[0049] Of course, in other embodiments, the first connecting part 120 is provided with a socket 213, and the assembly part 212 is fitted with the socket 213; the peripheral wall of the assembly part 212 is provided with a second plane 121, and the hole wall of the socket 213 is provided with a first plane 214. The first plane 214 and the second plane 121 are distributed opposite to each other to prevent the assembly part 212 and the first connecting part 120 from rotating relative to each other.

[0050] Alternatively, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The deep electrode implantation auxiliary device 010 also includes a first locking member 310, which is used to lock or unlock the assembly part 212 to the first connecting part 120. By locking the assembly part 212 and the first connecting part 120 with the first locking member 310, the stability of the stent 210 assembled on the guide 100 can be ensured, further improving the problem of the stent 210 accidentally moving relative to the guide 100, which would hinder the implantation of the deep electrode 420. After unlocking the assembly part 212 and the first connecting part 120 with the first locking member 310, the stent 210 can be easily removed from the guide 100, thus facilitating the cleaning and disinfection of the guide 100 and the stent 210 respectively.

[0051] Optionally, the first locking element 310 is a bolt, which can be threadedly connected to both the assembly portion 212 and the first connecting portion 120 simultaneously to lock the assembly portion 212 and the first connecting portion 120. When the bolt is at least separated from the first connecting portion 120, the assembly portion 212 and the first connecting portion 120 can be unlocked.

[0052] In other embodiments, the first locking member 310 may also be a screw or other threaded connector, etc., which are not specifically limited here.

[0053] It should be understood that in other embodiments of the deep electrode implantation auxiliary device 010 including the first locking member 310, the assembly part 212 and the first connecting part 120 may not be provided with the first plane 214 and the second plane 121. Alternatively, in embodiments where the assembly part 212 and the first connecting part 120 are respectively provided with the first plane 214 and the second plane 121, the assembly part 212 and the first connecting part 120 may not need to be locked with the first locking member 310.

[0054] In other embodiments, the assembly part 212 can also be detachably connected to the first connecting part 120 by means of threaded connection, snap-fit, etc.

[0055] Alternatively, please refer to Figure 1 The outer periphery of the assembly part 212 is provided with a third plane 215; the first locking member 310 can abut against the third plane 215. The provision of the third plane 215 can improve the stability of the first locking member 310 connected to the assembly part 212, thereby ensuring the stability of the assembly part 212 fixed to the first connecting part 120 by the first locking member 310.

[0056] Of course, the third plane 215 is not necessary. In other embodiments, the assembly part 212 may not have the third plane 215.

[0057] It should be noted that when using the deep electrode implantation assist device 010 to assist in the implantation of the deep electrode 420, the deep electrode implantation assist device 010 needs to be mounted on the robotic arm 020 of the stereotactic robot. To improve the stability of the deep electrode implantation assist device 010 mounted on the robotic arm 020 of the stereotactic robot, the deep electrode implantation assist device 010 also includes a fourth locking member 340. The fourth locking member 340 is detachably connected to the guide 100 and is used to fix the guide 100 to the robotic arm 020 of the stereotactic robot. That is, the fourth locking member 340 can simultaneously connect the guide 100 and the robotic arm 020 of the stereotactic robot, so that the deep electrode implantation assist device 010 is stably mounted on the robotic arm 020 of the stereotactic robot. Furthermore, when the fourth locking member 340 separates from at least one of the guide 100 and the robotic arm 020 of the stereotactic robot, the deep electrode implantation assist device 010 can be detached from the robotic arm 020 of the stereotactic robot.

[0058] Optionally, the fourth positioning element is a bolt, which simultaneously connects the guide 100 and the robotic arm 020 of the stereotactic robot, thereby stably assembling the deep electrode implantation auxiliary device 010 onto the robotic arm 020 of the stereotactic robot; when the bolt is separated from at least one of the guide 100 and the robotic arm 020 of the stereotactic robot, the deep electrode implantation auxiliary device 010 can be removed from the robotic arm 020 of the stereotactic robot.

[0059] Alternatively, please refer to Figure 1 and Figure 2 The guide 100 also includes a second connecting portion 130 connected to the guide body 110, and a guide hole 101 extends through the second connecting portion 130. The first connecting portion 120 and the second connecting portion 130 are located on opposite sides of the guide body 110. The robotic arm 020 of the stereotactic robot is provided with a socket, and the second connecting portion 130 is detachably inserted into the socket. The fourth positioning member can simultaneously connect the second connecting portion 130 and the robotic arm 020 of the stereotactic robot. When the fourth positioning member is at least separated from the robotic arm 020 of the stereotactic robot, the deep electrode implantation auxiliary device 010 can be detached from the robotic arm 020 of the stereotactic robot.

[0060] Optionally, a fourth plane 131 is provided on the outer periphery of the second connecting part 130. The fourth plane 131 is used to prevent the guide 100 from rotating relative to the mechanical arm 020 of the stereotactic robot when the second connecting part 130 is assembled with the mechanical arm 020 of the stereotactic robot, so as to improve the stability of the deep electrode implantation auxiliary device 010 assembled with the mechanical arm 020 of the stereotactic robot, thereby ensuring the ease of operation of deep electrode 420 implantation.

[0061] Optionally, the robotic arm 020 of the stereotactic robot is positioned on a mating plane that engages with the fourth plane 131. The relative engagement between the fourth plane 131 and the mating plane prevents the deep electrode implantation auxiliary device 010 from rotating relative to the robotic arm 020 of the stereotactic robot, thereby ensuring the stability of the installation of the deep electrode implantation auxiliary device 010 on the robotic arm 020 of the stereotactic robot.

[0062] Of course, the fourth plane 131 is not necessary. In other embodiments, the second connecting part 130 may not have the fourth plane 131.

[0063] It should be understood that, when adapting to different models of stereotactic robots, the structure, shape, etc. of the second connecting part 130 of the guide 100 can be adaptively adjusted.

[0064] In other embodiments, the deep electrode implantation assist device 010 may not include the fourth locking member 340, and the second connecting part 130 may be fixed to the robotic arm 020 of the stereotactic robot by means of threaded connection, snap-fit, or other means.

[0065] The connection methods between the first connecting part 120 and the second connecting part 130 and the guide body 110 include, but are not limited to, integral molding, welding, and threaded connection.

[0066] Alternatively, please refer to Figure 1 and Figure 3 In order to improve the stability of the cannula needle 410 inserted into the guide hole 101, the deep electrode implantation auxiliary device 010 also includes a third locking member 330, which is disposed on the guide 100 and used to fix the cannula needle 410 inserted into the guide hole 101.

[0067] Optionally, the third locking element 330 is a bolt threaded to the guide body 110; specifically, the guide body 110 is provided with a first threaded hole, and the bolt is threaded to the guide body 110 through the first threaded hole, and the first threaded hole communicates with the guide hole 101. When the bolt is tightened so that it extends into the guide hole 101 and abuts against the sleeve needle 410 inserted into the guide hole 101, the sleeve needle 410 can be fixed in the guide hole 101; when the bolt is loosened so that it no longer abuts against the sleeve needle 410, the sleeve needle 410 can be easily removed from the guide hole 101.

[0068] The structure of the clamping assembly 220 can be configured as needed; please refer to... Figure 1 In this embodiment, the clamping assembly 220 includes a clamp 221 and a second locking member 320. The clamp 221 is slidably disposed on the bracket 210. Specifically, the clamp 221 is slidably disposed on the bracket body 211 and is used to clamp the deep electrode 420. The second locking member 320 is used to lock or unlock the clamp 221 to the bracket body 211. When the second locking member 320 locks the clamp 221, the position of the clamp 221 relative to the bracket 210 is fixed. When the second locking member 320 unlocks the clamp 221, the clamp 221 can slide relative to the bracket 210.

[0069] The clamp 221 is configured to slide relative to the support body 211, which can stably clamp deep electrodes 420 of different sizes. That is, it ensures that deep electrodes 420 of various sizes can be stably implanted into the target point 030 without easy displacement. The clamp 221 is locked or unlocked by the second locking member 320, which ensures that the position of the clamp 221 relative to the support body 211 is easily adjustable, and also ensures the positional stability of the clamp 221 after adjustment.

[0070] Please refer to Figure 1 and Figure 4 The clamp 221 includes a first clamping part 222 and a second clamping part 223. The first clamping part 222 is slidably disposed on the bracket 210. The second clamping part 223 is movably connected to the first clamping part 222, and a clamping opening 224 is provided between the second clamping part 223 and the first clamping part 222. The clamping opening 224 is used to place the deep electrode 420. The second clamping part 223 can clamp the deep electrode 420 located in the clamping opening 224 together with the first clamping part 222. Since the second clamping part 223 can move relative to the first clamping part 222, the width of the clamping opening 224 can be increased when the deep electrode 420 needs to be placed in the clamping opening 224, so as to ensure the ease of operation of placing the deep electrode 420 in the clamping opening 224; and after the deep electrode 420 is placed in the clamping opening 224, the position of the second clamping part 223 can be adjusted to reduce the width of the clamping opening 224, so that the deep electrode 420 is stably clamped in the clamping opening 224 by the first clamping part 222 and the second clamping part 223.

[0071] Furthermore, the clamp 221 also includes an adjusting member 225. The second clamping part 223 is movably connected to the first clamping part 222 via the adjusting member 225. The adjusting member 225 is used to adjust the size of the clamping opening 224. The setting of the adjusting member 225 ensures the ease of operation in adjusting the position of the second clamping part 223 relative to the first clamping part 222, that is, ensures the ease of operation in adjusting the size of the clamping opening 224.

[0072] Optionally, the adjusting member 225 is a bolt, which is threadedly connected to both the first clamping part 222 and the second clamping part 223. By rotating the bolt, the second clamping part 223 can be moved closer to the first clamping part 222 to reduce the width of the clamping opening 224, or the second clamping part 223 can be moved away from the first clamping part 222 to increase the width of the clamping opening 224.

[0073] For example, please refer to Figure 5 The first clamping part 222 is provided with a first guide surface 226, and the second clamping part 223 is provided with a second guide surface 227. The first guide surface 226 and the second guide surface 227 are slidably engaged to guide the second clamping part 223 to move closer to or away from the first clamping part 222. Through the engagement of the first guide surface 226 and the second guide surface 227, it is ensured that when the bolt rotates, it will not cause the second clamping part 223 to rotate synchronously with it, but can only move in the direction of moving closer to or away from the first clamping part 222.

[0074] Of course, in other embodiments, the first clamping part 222 and the second clamping part 223 can also achieve a movable fit through other guiding structures, such as sliding grooves and ribs, etc., which are not specifically limited here.

[0075] It should be understood that in other embodiments, the adjusting member 225 may also be a torsion spring, and the second clamping part 223 is movably connected to the first clamping part 222 via the torsion spring. That is, one torsion arm of the torsion spring is connected to the second clamping part 223 (e.g., by welding, snap-fitting, etc.), and the other torsion arm of the torsion spring is connected to the first clamping part 222 (e.g., by welding, snap-fitting, etc.). When an external force is applied to press the second clamping part 223 and the torsion spring undergoes elastic deformation, the width of the clamping opening 224 between the first clamping part 222 and the second clamping part 223 can be increased; when the external force applied to the second clamping part 223 disappears, under the elastic restoring action of the torsion spring, the width of the clamping opening 224 between the second clamping part 223 and the first clamping part 222 narrows to clamp the deep electrode 420.

[0076] The sliding connection between the first clamping part 222 and the bracket body 211 can be selected as needed; please refer to... Figure 1 Optionally, the first clamping part 222 is provided with a sliding hole 228. The first clamping part 222 is sleeved on the bracket body 211 via a slider and can slide relative to the bracket body 211. The first clamping part 222 is provided with a second threaded hole, which communicates with the sliding hole 228. The second locking member 320 is a bolt, which is threadedly connected to the first clamping part 222 through the second threaded hole. When the bolt is tightened and pressed against the bracket body 211, the first clamping part 222 is locked onto the bracket body 211, thus locking its height. When the bolt is loosened and no longer pressed against the bracket body 211, the first clamping part 222 can slide relative to the bracket body 211 to adjust its position.

[0077] Optionally, the sliding hole 228 is a closed-loop hole. Of course, in other embodiments, the sliding hole 228 is not a non-closed-loop hole.

[0078] Of course, in other embodiments, the first clamping part 222 and the bracket body 211 can also be slidably connected by a slide rail assembly.

[0079] Alternatively, please refer to Figure 2 and Figure 3The guide 100 is provided with a reference surface 122. Specifically, the end face of the first connecting part 120 away from the guide body is the reference surface 122. The reference surface 122 is used to position the external needle 410 inserted into the guide hole 101. When using this deep electrode implantation auxiliary device 010, an external needle 410 of appropriate length can be selected according to the preoperative plan. When the external needle 410 is inserted into the guide hole 101 and implanted into the patient's body under the guidance of the guide hole 101, it can be determined whether the tip of the external needle 410 is implanted into the target point 030 by whether the external tube root of the external needle 410 (i.e., the tail of the unimplanted patient) is aligned (overlapped) with the reference surface 122. When the external tube root of the external needle 410 is aligned (overlapped) with the reference surface 122, it indicates that the tip of the external needle 410 has been implanted into the target point 030.

[0080] The alignment (coincidence) of the external tube root of the external cannula needle 410 with the reference surface 122 can mean that the marking on the external tube root of the external cannula needle 410 is aligned (coincidence) with the reference surface 122, and the tail end of the external cannula needle 410 protrudes relative to the reference surface 122.

[0081] Alternatively, please refer to Figure 1 The stent 210 is equipped with a scale; specifically, the stent body 211 is equipped with a scale, which is used to measure the implantation depth of the deep electrode 420. When implanting the deep electrode 420, the implantation depth can be determined according to the position of the scale corresponding to the unimplanted tail end of the deep electrode 420, so as to monitor the implantation status of the deep electrode 420 in real time.

[0082] The precision of the scale can be configured according to actual needs. For example, it can be accurate to 1 millimeter or 0.5 millimeters.

[0083] To facilitate cleaning and disinfection, all components of the deep electrode implantation auxiliary device 010 can be made of high-temperature resistant and corrosion-resistant materials, such as stainless steel, aluminum alloy, and PEEK.

[0084] It should be noted that the deep electrode implantation auxiliary device 010 in this embodiment can be used for manual implantation of the deep electrode 420, thus eliminating the need for a drive mechanism such as a motor, reducing production difficulty, and also helping to reduce costs.

[0085] It should also be noted that, in order to ensure that the various locking and adjusting components 225 do not interfere with each other when using the deep electrode implantation auxiliary device 010, thus preventing operational inconvenience, please refer to... Figure 1 and Figure 2The first locking member 310 and the third locking member 330 do not coincide in the axial direction of the guide hole 101. For example, the angle between the first locking member 310 and the third locking member 330 in the circumferential direction of the guide hole 101 is 90°. The fourth locking member 340 and the third locking member 330 do not coincide in the axial direction of the guide hole 101. For example, the angle between the fourth locking member 340 and the third locking member 330 in the circumferential direction of the guide hole 101 is 90°. The adjusting member 225 and the second locking member 320 are respectively located on both sides of the width direction of the bracket body 211.

[0086] Please refer to Figures 1-4 ,as well as Figure 6 and Figure 7 The process of implanting a deep electrode 420 using the deep electrode implantation auxiliary device 010 in this embodiment includes:

[0087] 1. Install the guide 100 onto the robotic arm 020 of the stereotactic robot; 2. Adjust the position of the robotic arm 020 of the stereotactic robot according to the preoperative plan, insert the cannula needle 410 into the guide hole 101 until the outer tube root of the cannula needle 410 coincides with the reference plane 122. At this time, the tip of the cannula needle 410 is located at the implantation target point 030. Fix the cannula needle 410; 3. Test the deep electrode 420 according to the length of the cannula needle 410, and mark the corresponding length position with a sterile marker; 4. Remove the needle body of the cannula needle 410 and insert the deep electrode 420 into the cannula needle 410; 5. Assemble the clamping mechanism 200 onto the guide 100, and make the clamping assembly 220 and the cannula needle 410 fit together. The deep electrodes 420 are not in contact with each other. Insert the deep electrodes 420 along the outer cannula needle 410 until the marked position of the deep electrode 420 coincides with the outer cannula root of the outer cannula needle 410. The deep electrode 420 is implanted at the target point 030. 6. Adjust the position of the clamping assembly 220 and make the clamping assembly 220 clamp the deep electrode 420. 7. Pull out the mandrel 430 inside the deep electrode 420. 8. Make the clamping assembly 220 no longer clamp the deep electrode 420 and disassemble the clamping mechanism 200 and the outer cannula needle 410. 9. Use medical tweezers to clamp the deep electrode 420 near the skin, and then disassemble the clamping mechanism 200, the outer cannula needle 410, the guide 100, and remove the robotic arm. 10. Fix the deep electrode 420 and complete the implantation.

[0088] In summary, the deep electrode implantation auxiliary device 010 of this utility model can ensure that the deep electrode 420 is reliably located at the target point 030 after the deep electrode 420 is implanted into the target point 030 and during the process of removing the mandrel 430 from the deep electrode 420, that is, it improves the problem that the deep electrode 420 is displaced after being implanted into the target point 030 and then moved out with the removal of the mandrel 430.
