Abstract
Description
Technical Field
[0001] This invention relates to the field of surgical instrument technology, and more specifically, to a DBS surgical electrode insertion system and a method for inserting the DBS electrode for drilling holes in the skull. Background Technology
[0002] Deep brain stimulation (DBS), also known as brain pacemaker implantation, works by delivering high-frequency electrical stimulation to motor control nuclei (such as the medial globus pallidus-GPi and the subthalamic nucleus-STN) via electrodes implanted in the brain. The stimulation signals interfere with abnormal neural activity, restoring motor control circuits or disordered neurotransmitters to a relatively normal functional state, thereby alleviating motor dysfunction symptoms and improving quality of life. In the surgical procedure of DBS, drilling into the skull is required. The skull drilling fixation frame is a crucial auxiliary device for this procedure and a significant factor affecting its success.
[0003] Existing technology has proposed an optimized structure for the DBS surgical electrode insertion system used in skull drilling. Patent publication number CN121287444 A, entitled "Anti-vibration Fixation Bracket for Skull Drilling Surgery," provides an anti-vibration fixation bracket for skull drilling surgery. This bracket significantly counteracts the load generated by the impact between the high-speed skull drill and the skull through the rebound force of the radial buffer spring and the buffering effect of the hydraulic fluid, preventing direct transmission of the impact. While this device can aid in the positioning of the skull drill to some extent, in actual electrode implantation surgery, it requires numerous adapter heads, repeated installation and positioning, and on-site disassembly and adjustment of related equipment, resulting in complex operations and significant time consumption.
[0004] In view of this, there is an urgent need for a DBS surgical electrode insertion system for skull drilling that can quickly complete the assembly of the instruments required during the operation, effectively shorten the operation time, and improve the efficiency of the operation while ensuring accuracy.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0026] It should be noted that if the embodiments of the present invention involve directional indications, such as up, down, left, right, front, back, etc., these directional indications are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly. Furthermore, if the embodiments of the present invention involve descriptions such as "first," "second," "S1," "S2," "step one," "step two," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance, or implicitly indicating the number of technical features indicated or the order of method execution. Those skilled in the art will understand that anything that does not violate the inventive concept and is within the scope of the present invention should be included in the protection scope of the present invention.
[0027] like Figure 1 As shown, a DBS surgical electrode insertion system according to one embodiment includes: a connecting part 10 for connecting to an external surgical platform; an adapter part 20; one end detachably fixed to the connecting part 10; and a rotating part 30 having multiple instrument mounting parts 35 respectively matched with different instruments 40. The rotating part 30 is rotatably mounted on the adapter part 20 for aligning selected instrument mounting parts 35 with the adapter part 20. Each instrument 40 includes at least a cranial drill, an implantable electrode, and an injection device. Along the direction of travel of the instrument 40, the instrument 40 extends and retracts through the adapter part 20 and is connected in an orderly manner with the instrument mounting parts 35 on the rotating part 30. The rotating part 30 and the adapter part 20 are used to support and guide the selected instrument 40 to operate on the target surgical site.
[0028] Therefore, by rotatably setting the rotating part 30 and setting multiple instrument mounting parts 35, instruments 40 of different specifications can be quickly assembled without repeated installation and positioning. This allows for efficient and flexible switching of instruments 40 at different stages of the implantation electrode surgery, effectively shortening the operation time. When different instruments 40 need to be replaced, the target type of instrument 40 pre-installed on the instrument mounting part 35 of the rotating part 30 can be rotated to align the corresponding instrument mounting part 35 with the adapter part 20 by rotating the rotating part 30. Then, the formal installation can be completed based on the pre-installation. The rotating part 30 and the adapter part 20 work together to support and guide the movement of instruments 40 of different sizes. During the operation, after the DBS surgical electrode needle insertion system is connected to the surgical platform through the connecting part 10 and undergoes one intelligent calibration, it is not necessary to disassemble and recalibrate the DBS surgical electrode needle insertion system when the instrument 40 needs to be replaced. This makes it convenient for doctors to quickly complete the assembly of various types of instruments 40 required during the operation. Through the support and guidance of the adapter part 20 and the limiting of the rotating part 30, it is ensured that instruments 40 of different specifications can always be in the same position after installation. For example, in DBS surgery, it is ensured that the implantable electrode can be implanted based on the same position after drilling the cranial drill, and then the implantable electrode can be positioned by injecting glue based on the same position, which significantly improves the accuracy of the operation. Thus, the design of the DBS surgical electrode insertion system can effectively shorten the operation time and improve the efficiency of the operation while ensuring accuracy.
[0029] In some implementations, such as Figure 1 and Figure 2 As shown, the connecting part 10 is a frame welded from a panel and a support beam, thus possessing sufficient rigidity to load and withstand uncertain positional loads. Specifically, the connecting part 10 includes a fixed base 11, a connecting arm 12, and a mounting base 13, wherein the fixed base 11 and the mounting base 13 are respectively disposed on both ends of the connecting arm 12; the mounting base 13 has a cylindrical shape and an internal cavity with an upward opening; optionally, the internal cavity of the mounting base 13 is formed as an irregular geometric cavity; preferably, the cross-section of the internal cavity of the mounting base 13 is racetrack-shaped. Thus, based on the racetrack-shaped cavity provided in the mounting base 13, the circumferential degree of freedom of the adapter 20 after installation is restricted, avoiding the risk of positional deviation caused by rotation based on the axis.
[0030] Optionally, in order to further ensure the reliability and firmness of the adapter 20 and the connecting part 10 after installation, a locking mechanism is also provided that penetrates the periphery of the mounting base 13 in the radial direction of the mounting base 13, such as a locking screw that penetrates the periphery of the mounting base 13. For the sake of distinction, the locking mechanism on the mounting base 13 is referred to as the first locking mechanism.
[0031] Therefore, the connecting part 10 provided in this embodiment provides sufficient installation and operating space for the adapter part 20 and the rotating part 30 through the fixed base 11 and the mounting base 13 respectively disposed at both ends of the connecting arm 12; by setting the internal cavity of the mounting base 13 as an irregular geometric cavity, the circumferential degree of freedom of the adapter part 20 after installation is restricted, avoiding the risk of position deviation caused by rotation based on the axis; furthermore, by using the locking mechanism provided through the peripheral side of the mounting base 13 along the radial direction of the mounting base 13, the reliability and firmness of the connection between the adapter part 20 and the connecting part 10 can be improved.
[0032] In some implementations, such as Figure 2 and Figure 3 As shown, the adapter 20 has an overall T-shaped structure. Specifically, the adapter 20 includes an extension mechanism 21, a support mechanism 22, and a connecting mechanism 23 connected as a single unit. One end of the extension mechanism 21 is fixed to the top surface of the support mechanism 22, and the other end extends upward along the plumb line. One end of the connecting mechanism 23 is fixed to the bottom surface of the support mechanism 22, and the other end extends downward along the plumb line. One end of the support mechanism 22 is connected to the extension mechanism 21 and the connecting mechanism 23, and the other end extends in a direction perpendicular to the extension mechanism 21. Thus, the T-shaped structure formed by the extension mechanism 21 on the top surface of the support mechanism 22 and the connecting mechanism 23 on the bottom surface of the support mechanism 22 avoids equipment interference and provides more usable space for the DBS surgical electrode insertion system after it is connected to the surgical platform. Furthermore, the extension mechanism 21, which extends upward along the plumb line, provides sufficient guiding and corrective working space for the instrument 40. For example, when using a skull drill to drill holes in the skull, different guiding and correcting mechanisms can be set along the length of the skull drill through the upward-extending extension mechanism 21 to counteract the linear displacement of the drill caused by vibration or the deflection of the length of the skull drill itself during the drilling process, thereby ensuring the accuracy of the entire drilling.
[0033] Optionally, the extension mechanism 21 includes an extension support column 211, an extension connecting hole 212, and an extension locking hole 213. The extension support column 211 is fixed to the bottom end face of the support mechanism 22, extends upward in a direction perpendicular to the top end face of the support mechanism 22, and has a boss 214 located at the far end away from the support mechanism 22. The extension connecting hole 212 is opened on the top end face of the boss 214 of the extension support column 211 and extends through the extension support column 211 along its length. The extension locking hole 213 extends through the side of the boss 214 on the support mechanism 22 and intersects with the extension connecting hole 212. Thus, the extension connecting hole 212 opened on the boss 214 of the extension support column 211 provides a convenient and quick installation method for the auxiliary part 50, and the extension locking hole 213 achieves a reliable and stable connection.
[0034] Optionally, the boss 214 provided on the end side of the extended support column 211 extends parallel to the length direction of the support mechanism 22. Thus, the boss 214, which is parallel to the support mechanism 22, provides a fixed platform for the instrument part 40, so that the auxiliary part 50 and the instrument mounting part 35 can be brought as close as possible. This allows for continuous and stable guidance and correction of the instrument 40 with minimal space requirements.
[0035] Optionally, the extended locking hole 213 is perpendicular to the end side of the extended support column 211 and intersects perpendicularly with the extended connecting hole 212; thus, the extended locking hole 213, which is perpendicular to the end side of the extended support column 211, provides a quick and easy locking method, which simplifies the entire installation process of the bracket while ensuring the reliability of the installation connection, and shortens the installation and debugging time of the instrument 40 for surgery.
[0036] Optional, such as Figure 2As shown, the support mechanism 22 includes a support platform 221, a limiting through hole 222 and a rotation fixing hole 224 provided on the support platform 221. One end of the support platform 221 is connected to the extension mechanism 21, and the other end extends along the length direction perpendicular to the extension mechanism 21. The limiting through hole 222 is provided through the support platform 221 along the length direction parallel to the extension mechanism 21. The rotation fixing hole 224 is provided through the support platform 221 along the length direction parallel to the extension mechanism 21 and is located at the far end of the support platform 221 away from the extension mechanism 21. Thus, the limiting through hole 222 provided through the support platform 221 provides a reliable axial restriction for the instrument mounting part 35, thereby effectively eliminating the circumferential vibration of the instrument mounting part 35 during rotation operation and effectively ensuring the operation quality of the instrument 40. The rotation fixing hole 224 is located on the end side of the support platform 221 away from the extension mechanism 21, further reducing the space occupied and improving the integration of the entire DBS surgical electrode needle insertion system.
[0037] Optionally, the rotating fixing hole 224 is cylindrical in shape, and its internal through hole is threaded. Further, the top surface of the rotating fixing hole 224 protrudes from the top surface of the support platform 221.
[0038] Optionally, the limiting through hole 222 is located at the end of the connection between the support platform 221 and the extension mechanism 21; thereby, the gap between the instrument mounting part 35 and the instrument 40 and the extension mechanism 21 through the limiting through hole 222 can be minimized as much as possible, thereby eliminating the error caused by the distance between them and the extension mechanism 21, which is beneficial for calibrating the coaxiality between the extension mechanism 21 and the instrument mounting part 35.
[0039] Optionally, to facilitate the positioning and locking of the rotating part 30 during the switching process, such as... Figure 3 As shown, it also includes mounting holes 223 that penetrate the support platform 221.
[0040] Furthermore, the connecting mechanism 23 is a columnar body disposed on the bottom end surface of the support mechanism 22. Specifically, in a specific example of this application, the connecting mechanism 23 is a columnar body designed to match the mounting base 13 on the connecting part 10, for example, a columnar body with a racetrack-shaped cross-section.
[0041] Optional, such as Figure 3As shown, to further facilitate the quick and precise assembly and disassembly of the rotating part 30, the adapter part 20 also includes a fixing mechanism 24 for mounting the rotating part 30. The fixing mechanism 24 passes through the rotating part 30 and is detachably connected to the support mechanism 22. The fixing mechanism 24 detachably connects the rotating part 30 to the support mechanism 22 of the adapter part 20, and the rotating part 30 can rotate around the fixing mechanism 24 until the instrument mounting part 35 is aligned with the adapter part 20. Specifically, the fixing mechanism 24 includes a fixing bolt 241 and at least one bearing 242, wherein the bearing 242 is sleeved on the fixing bolt 241 and is rotatably configured with respect to the fixing bolt 241; the fixing bolt 241 passes through the rotating part 30 and is detachably connected to the support mechanism 22. Preferably, the bearings 242 are arranged in pairs. Further, there are two bearings 242, which are arranged between the rotating part 30 and the fixing bolt 241, and between the rotating part 30 and the support mechanism 22. For example, in an optional embodiment, the rotating part 30 is provided with a pivot hole that is directly opposite to the rotation fixing hole 224 of the support mechanism 22. The bearing 242 is disposed in the pivot hole of the rotating part 30 and between the fixing bolt 241 and the rotation fixing hole 224. Thus, sliding friction is formed between the rotating part 30 and the fixing bolt 241 and the rotation fixing hole 224, thereby ensuring the stability of the DBS surgical electrode needle insertion system during operation.
[0042] Optional, such as Figure 3 As shown, the adapter 20 further includes a limiting mechanism 25 fixed to the rotating part 30 and releasably locked to the support mechanism 22. Specifically, the limiting mechanism 25 passes through the rotating part 30 and is releasably locked to the support mechanism 22. The limiting mechanism 25 includes a spring plunger 251 and at least one limiting hole 252, wherein the spring plunger 251 is releasably compressed against the top surface of the support mechanism 22; the limiting hole 252 is formed on the bottom surface of the rotating part 30 and is spaced along the rotation trajectory of the rotating part 30. Preferably, the spring plunger 251 passes through the support mechanism 22 and is releasably compressed against the top surface of the support mechanism 22. Further, the position of the limiting hole 252 corresponds to the position where the instrument mounting part 35 passes through the support mechanism 22.
[0043] The adapter 20 provided in the above embodiment provides a convenient and quick installation method for the auxiliary part 50 through the extension connection hole 212 on the boss 214 on the extension support column 211. Under the action of the extension locking hole 213, a more reliable and stable connection is achieved. The boss 214, which is parallel to the support mechanism 22, provides a fixed platform for the auxiliary part 50, allowing the auxiliary part 50 to be as close as possible to the instrument installation part 35. This enables continuous and stable guidance and correction of the instrument 40 with minimal space occupation. The extension locking hole 213, which is perpendicular to the side of the extension support column 211, provides a quick and simple locking method. While ensuring the reliability of the installation connection, it simplifies the installation process of the entire DBS surgical electrode needle insertion system and shortens the installation and debugging time of the instrument 40 for surgery. By setting the limiting through hole 222 close to the extension support column 211, the gap between the instrument 40 passing through the limiting through hole 222 and the extension mechanism 21 is minimized as much as possible, thereby eliminating the error caused by the distance between them and the extension mechanism 21, and eliminating the adverse effects of the extension mechanism 21 on the assembly of the instrument mounting part 35. Sliding friction is formed between the rotating part 30 and the fixing bolt 241 and the rotating fixing hole 224, thereby ensuring the stability of the DBS surgical electrode needle insertion system during operation. The T-shaped structure formed by the extension mechanism 21 set on the top surface of the support mechanism 22 and the connecting mechanism 23 set on the bottom surface of the support mechanism 22 can improve the utilization rate of space without equipment interference. The extension mechanism 21, which extends along the plumb line, can provide sufficient guiding and corrective working space for the instrument mounting part 35.
[0044] In some implementations, such as Figure 1 and Figure 4 As shown, the rotating part 30 is a frame structure formed by connecting a panel and supporting ribs, thus possessing sufficient rigidity to load and withstand uncertain positional loads. Specifically, the rotating part 30 includes a rotating arm 31, a first rotating part 32, and a second rotating part 33, wherein the first rotating part 32 and the second rotating part 33 are disposed at both ends of the rotating arm 31; the first rotating part 32 and the second rotating part 33 are arranged parallel to each other along the length direction perpendicular to the rotating arm 31, and together with the rotating arm 31, they form a frame with an internal storage cavity; the instrument mounting part 35 is disposed at the distal end of the first rotating part 32 and the second rotating part 33 away from the rotating arm 31. Thus, by setting the first rotating part 32 and the second rotating part 33 at both ends of the rotating arm 31 and arranging them in parallel, a frame with an internal storage cavity is formed inside the rotating part 30, which can accommodate the rotation center and related fixing components inside the cavity, thereby achieving rotational function while further reducing space occupation and improving the flexibility and scenario applicability of the DBS surgical electrode insertion system.
[0045] Optionally, the first rotating part 32 and the second rotating part 33 are located on the upper and lower sides of the connection position between the adapter part 20 and the connecting part 10. The instrument 40, mounted on the adapter part 20, has the first rotating part 32, the adapter part 20, and the second rotating part 33 sequentially inserted along the direction of travel of the instrument 40, which can more stably guide the movement of the instrument 40 along its axial direction. The similar outer contours of the first rotating part 32 and the second rotating part 33 improve space utilization efficiency while ensuring strength, thus meeting the needs of surgical space-constrained scenarios.
[0046] Optionally, the first rotating part 32 and the second rotating part 33 are provided with through holes for the instrument 40 to pass through, and the axial positions of the through holes on the first rotating part 32 and the second rotating part 33 are arranged in a one-to-one correspondence. Therefore, by providing one-to-one corresponding through holes on the first rotating part 32 and the second rotating part 33, the accuracy of the instrument mounting part 35 during installation can be ensured, and errors caused by vibrations along the length of the instrument mounting part 35 during operation can be reduced, effectively improving the operational accuracy of the instrument mounting part 35.
[0047] The rotating part 30 provided in the above embodiment, through the first rotating part 32 and the second rotating part 33 arranged in parallel on both sides of the rotating arm 31, forms a frame with an internal storage cavity inside the rotating part 30, which can accommodate the rotation center and related fixing components inside the cavity, thereby achieving rotation function while further reducing space occupation and improving the flexibility and applicability of the DBS surgical electrode needle insertion system; through the one-to-one corresponding through holes opened on the first rotating part 32 and the second rotating part 33, the accuracy of the instrument 40 during the installation process can be ensured, and the error caused by the vibration of the instrument 40 along the length direction during operation can be reduced, which can effectively improve the operating accuracy of the instrument 40.
[0048] In some implementations, such as Figure 5As shown, to reduce errors caused by the deflection of the instrument mounting section 35 during operation, the DBS surgical electrode insertion system also includes an auxiliary section 50. One end of the auxiliary section 50 is detachably fixed to the top of the adapter section 20; the other end, which is opposite to it, extends along the length of the instrument 40 and away from the rotating section 30. Specifically, the auxiliary section 50 includes an auxiliary extension rod 51, a locking mechanism, and at least one clamping mechanism 53. For ease of description, the locking mechanism in the auxiliary section 50 is referred to as the second locking mechanism 52. The bottom end of the auxiliary extension rod 51 is detachably fixed to the top of the adapter section 20, while the other end, which is opposite to it, extends along the length of the instrument mounting section 35 and away from the rotating section 30. The second locking mechanism 52 passes through the boss 241 at the top of the adapter section 20 and the auxiliary extension rod 51, and is lockably secured to the adapter section 20. The clamping mechanisms 53 are spaced apart along the length of the auxiliary extension rod 51. Therefore, the second locking mechanism 52 can quickly and efficiently assemble and disassemble the auxiliary extension rod 51 and the adapter 20. The clamping mechanism 53, which is spaced apart from the protrusion 241 of the adapter 20 along the length direction of the auxiliary extension rod 51, can effectively offset the error caused by factors such as deflection and rotation in the length direction of the instrument 40, and further ensure the accuracy of the instrument 40 operation.
[0049] Furthermore, the instruments 40 mentioned in this application are all instruments used in DBS (deep brain stimulation) surgery. They can be one or a combination of medical devices such as cranial drills, implantable electrodes, and injection devices, or surgical instruments used in other surgeries. As long as they meet the requirements of repeated operations on the same location, high operational requirements, and the need for rapid switching, no specific limitations are made here.
[0050] In some embodiments, the bottom end of the auxiliary extension rod 51 is detachably fixed to the extension connection hole 212 of the extension support column 211, and the second locking mechanism 52 fixes the auxiliary extension rod 51 through the extension locking hole 213. By adding the auxiliary extension rod 51 to the extension mechanism 21, the guidance and correction of the instrument mounting part 35 in the length direction can be further enhanced, thereby effectively improving the support and calibration function of the DBS surgical electrode needle insertion system for the instrument mounting part 35.
[0051] The auxiliary part 50 provided in the above embodiment can quickly and efficiently assemble and disassemble the auxiliary extension rod and the adapter part through the second locking mechanism 52. The clamping mechanism 53, which is spaced along the length direction of the auxiliary extension rod 51, can effectively offset the error caused by factors such as deflection and rotation of the instrument 40 in the length direction, thus ensuring the accuracy of the instrument 40 in operation.
[0052] Furthermore, in the embodiments of this application, the locking mechanism can be one or a combination of locking bolts, hydraulic locking, pneumatic locking, and electromagnetic locking devices. The specific structure, principle, or other structural forms that achieve the same function of the locking mechanism should be easily conceived by those skilled in the art, and therefore will not be described in detail here.
[0053] Furthermore, the specific structure of the clamping mechanism can be a bolt-fixed structure with a central hole, or a structure that uses an elastic pressure plate to drive the retaining ring. No specific limitations are made here, as long as it fulfills the function of guiding and correcting the instrument 40. The specific structure, principle, or other structural forms that achieve the same function should be easily conceived by those skilled in the art, so they will not be elaborated here.
[0054] In addition, it includes cables and other auxiliary equipment. For example, control switches, which should be easily conceived by those skilled in the art, will not be described in detail here.
[0055] The DBS surgical electrode insertion system provided in the above embodiments of this application has at least the following characteristics: (1) The adapter’s structural design utilizes multiple instrument mounting parts 35 to pre-install different types of instruments 40 that need to be used. When different instruments need to be replaced, the different instrument mounting parts 35 of the rotating part 30 can be rotated to cooperate with the adapter 30. Therefore, during the operation, after the DBS surgical electrode needle insertion system is connected to the surgical platform through the connecting part 10 and calibrated once, when instruments need to be replaced later, there is no need to disassemble and recalibrate the DBS surgical electrode needle insertion system. This makes it convenient for doctors to quickly complete the assembly of the instruments required during the operation. On the basis of ensuring accuracy, it can effectively shorten the operation time.
[0056] (2) The structural design of the adapter 20, through the extension connection hole 212 provided on the boss 214 of the extension support column 211, can provide a convenient and quick installation method for the auxiliary part 50, and then achieve a reliable and stable connection under the action of the extension locking hole 213; on the adapter 20, through the boss 214 provided parallel to the support mechanism 22, a fixed platform is provided for the auxiliary part 50, so that the auxiliary part 50 and the instrument 40 can be brought as close as possible, thereby continuously and stably guiding and correcting the instrument 40 with minimal space occupation; the extension locking hole 213 provided on the boss 214 perpendicular to the end side of the extension support column 211 provides a quick and simple locking method, which can simplify the installation and debugging time of the instrument 40 while ensuring the reliability of the installation connection; the limiting through hole 222 can The distance between the instrument 40 and the extension mechanism 21 can be minimized as much as possible, thereby improving the coaxiality between the instrument 40 and the extension mechanism 21 and eliminating the error caused by the distance between them. This also eliminates the adverse effects of the extension mechanism 21 on the installation and operation of the instrument 40. The design of the fixing mechanism 24 creates sliding friction between the rotating part 30 and the fixing bolt 241 and the rotating fixing hole 224, thereby ensuring the stability of the DBS surgical electrode needle insertion system during operation. The T-shaped structure formed by the extension mechanism 21 set on the top surface of the support mechanism 22 and the connecting mechanism 23 set on the bottom surface of the support mechanism 22 can improve the utilization of space while avoiding equipment interference. The extension mechanism 21, which extends along the plumb line, can provide sufficient guiding and corrective working space for the instrument 40.
[0057] (3) The structural design of the connecting part 10, through the fixed base 11 and the mounting base 13 respectively located at both ends of the connecting arm 12, can provide sufficient installation and working space for the adapter part 20 and the rotating part 30; by setting the internal cavity of the mounting base 13 as an irregular geometric cavity, the circumferential freedom of the adapter part 20 after installation can be restricted, avoiding the risk of position deviation caused by the rotation of the axis; by the locking mechanism provided through the circumferential side of the mounting base 13 along the radial direction of the mounting base 13, the reliability and firmness of the connection between the adapter part 20 and the connecting part 10 can be improved.
[0058] (4) The structural design of the rotating part 30 is achieved by setting the first rotating part 32 and the second rotating part 33 on both sides of the rotating arm 31 and setting them in parallel. A frame structure with an internal storage cavity is formed inside the rotating part 30, which can accommodate the rotation center and related fixed parts inside the cavity. This achieves the function of rotation while further reducing the space occupied and improving the flexibility and applicability of the DBS surgical electrode needle insertion system. Through the one-to-one corresponding through holes opened in the first rotating part 32 and the second rotating part 33, the accuracy of the instrument 40 during installation can be improved, and the error caused by the vibration of the instrument 40 along the length direction during operation can be reduced, which can effectively improve the operating accuracy of the instrument 40.
[0059] Please see Figure 6 In another aspect, this application provides a method for inserting a DBS electrode, implemented using the DBS surgical electrode insertion system described in any embodiment of this application, including: S101, multiple instruments are pre-assembled on the instrument mounting part, and after connecting to an external surgical platform through the connecting part and completing the calibration, the instrument mounting part on the rotating part, which is pre-assembled with the first instrument, is aligned with the adapter part. S102, After the first instrument is used, adjust the instrument mounting part on the rotating part, which is pre-assembled with the second instrument, to align with the adapter part. S103, repeat this process to complete the instrument replacement.
[0060] It should be noted that the DBS electrode insertion method implemented by the DBS surgical electrode insertion system provided in this application embodiment is not limited to actual surgical operations, but can be used for instrument replacement practice before surgery, and for instrument calibration and re-verification practice after the DBS surgical electrode insertion system is connected to a surgical platform, such as a surgical robot. The first instrument and the second instrument can be, in sequence, a cranial drill, an implantable electrode, and a glue injector, to provide doctors with familiarity with surgical instrument operation and practice instrument use.
[0061] In the above embodiments, the DBS electrode insertion method, through the design of an integrated adapter that supports the assembly of various instruments, allows the surgeon to quickly complete the assembly and use of the next instrument by simply connecting the adapter to the external surgical platform via the connector and performing one calibration during the operation, and then adjusting the rotating part. This not only significantly reduces the time required for electrode insertion during DBS surgery, effectively shortening the total operation time, but also improves the accuracy of implantable electrode insertion.
[0062] Please see Figure 7The DBS surgical electrode insertion system also includes an electrode cover 60, which includes an electrode groove 61 formed on a surface and positioning holes 62 located on both sides of the electrode groove 61. The method further includes: placing the electrode cover 60 on the target position, wherein the electrode groove 61 of the electrode cover 60 is used for receiving and passing through the DBS electrode, and the electrode cover 60 is fixed through the positioning holes 62.
[0063] The electrode cap 60 is designed to enhance the stability of the implanted electrode after insertion, preventing displacement or detachment. The fixation method using the electrode cap 60 effectively reduces the time required for electrode fixation after insertion during DBS surgery, thus shortening the total surgical time and improving the reliability and stability of the implanted electrode.
