Description

Technical Field

[0001] This invention relates to the field of surgical instrument technology, and more specifically, to a surgical stent for DBS surgery. 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 surgical stents used in skull drilling. Patent publication number CN121287444 A, entitled "Anti-vibration Fixation Stent for Skull Drilling Surgery," provides an anti-vibration fixation stent for skull drilling surgery. This stent significantly offsets the load generated by the impact between the high-speed drill bit and the skull through the rebound force of the radial buffer spring and the buffering effect of the hydraulic fluid flow, preventing direct transmission of the impact. While this device can aid in the positioning of the skull drill hole to some extent, in actual surgery to implant electrodes, 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 surgical scaffold for drilling into the skull, which can quickly assemble the instruments required during the operation, effectively shorten the operation time, and improve the efficiency of the operation while ensuring accuracy. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a surgical stent for drilling holes in the skull, which can quickly assemble the instruments required during the operation, effectively shorten the operation time, and improve the efficiency of the operation while ensuring accuracy.

[0006] To achieve the above objectives, the technical solution of this invention is implemented as follows: A surgical support includes: a connecting portion for connecting to an external surgical platform; an adapter portion; one end of the connecting portion detachably fixed for supporting and guiding the smooth operation of an instrument; and a rotating portion including an instrument mounting portion disposed on the end side, the rotating portion being rotatably mounted on the adapter portion; wherein, along the direction of travel of the instrument, the instrument is telescopically extending through the adapter portion and is connected in an orderly manner with the rotating portion.

[0007] Furthermore, the connecting part includes a fixed base, a connecting arm, and a mounting base, wherein the fixed base and the mounting base are respectively disposed on both ends of the connecting arm; the mounting base has a cylindrical shape and has an internal cavity with an upward opening.

[0008] Furthermore, the adapter includes an extension mechanism, a support mechanism, and a connecting mechanism connected as one unit. One end of the extension mechanism is fixed to the top surface of the support mechanism, and the other end, which is opposite to it, extends upward along the plumb line. One end of the connecting mechanism is fixed to the bottom surface of the support mechanism, and the other end, which is opposite to it, extends downward along the plumb line. One end of the support mechanism is connected to the extension mechanism and the connecting mechanism, and the other end, which is opposite to it, extends in a direction perpendicular to the extension mechanism.

[0009] Furthermore, the extension mechanism includes an extension support column, an extension connecting hole, and an extension locking hole. The extension support column is fixed to the bottom end face of the support mechanism, extends upward in a direction perpendicular to the top end face of the support mechanism, and has a boss located at the far end away from the support mechanism. The extension connecting hole is opened on the top end face of the boss of the extension support column and extends through the column along its length. The extension locking hole extends through the side of the boss of the support mechanism and intersects with the extension connecting hole.

[0010] Furthermore, the support mechanism includes a support platform, a limiting through hole, and a rotating fixing hole. One end of the support platform is connected to the extension mechanism, and the other end, which is opposite to it, extends along the length direction perpendicular to the extension mechanism. The limiting through hole extends through the support platform along the length direction parallel to the extension mechanism. The rotating fixing hole extends through the support platform along the length direction parallel to the extension mechanism and is located at the far end of the support platform away from the extension mechanism.

[0011] Furthermore, the adapter also includes a fixing mechanism 24 that is rotatably mounted to the rotating part, and the fixing mechanism is detachably connected to the support mechanism after passing through the rotating part.

[0012] Furthermore, the fixing mechanism includes a fixing bolt and at least one bearing, wherein the bearing is sleeved on the fixing bolt and is rotatably mounted on the fixing bolt; the fixing bolt passes through the rotating part and is detachably connected to the support mechanism.

[0013] Furthermore, the adapter also includes a limiting mechanism that is fixed to the rotating part and is releasably locked to the support mechanism.

[0014] Furthermore, the rotating part includes a rotating arm, a first rotating part, and a second rotating part, wherein the first rotating part and the second rotating part are disposed at both ends of the rotating arm; the first rotating part and the second rotating part are arranged parallel to each other along the length direction perpendicular to the rotating arm, and together with the rotating arm, they form a frame with an internal storage cavity, and the instrument mounting part is disposed at the far end of the first rotating part and the second rotating part away from the rotating arm.

[0015] Furthermore, it also includes an auxiliary part that is detachably fixed to the top of the adapter at one end; and an auxiliary part that is disposed opposite to the adapter at the other end, extending along the length of the device in a direction away from the rotating part.

[0016] The surgical stent provided in the above embodiment is composed of three parts: a connecting part, an adapter part, and a rotating part. The instrument is located at the end of the rotating part and extends through the adapter part, and is connected to the rotating part in an orderly manner. The adapter part and the connecting part are detachably connected, and the rotating part can be switched and locked to the fixed part. Thus, when different instruments need to be replaced, the rotating part can be rotated to complete the replacement. The rotating part and the adapter part are then rotated to support and guide the movement of the instrument. During the operation, after the surgical stent is connected to the surgical platform through the connecting part and undergoes intelligent calibration once, the surgical stent does not need to be disassembled and recalibrated when instruments need to be replaced. This allows the doctor to quickly complete the assembly of the instruments required during the operation, effectively shortening the operation time and improving the efficiency of the operation while ensuring accuracy.

[0017] Furthermore, in the structural design of the connecting part, the fixed base and mounting base located at both ends of the connecting arm provide ample installation and operating space for the adapter and rotating parts. Moreover, the mounting base has a cylindrical shape, and its internal cavity can be designed as an irregular geometric cavity, restricting the circumferential freedom of the adapter after installation and avoiding the risk of positional deviation caused by axis-based rotation.

[0018] Furthermore, in the structural design of the adapter, the extension mechanism, through a locking mechanism that penetrates the circumference of the mounting base in the radial direction, ensures the reliability and firmness of the connection between the adapter and the connecting part. Moreover, the extension mechanism, with its extension connection holes on the protrusions of the extension support columns, provides a convenient and quick installation method for the auxiliary part, achieving a secure and stable connection through the extension locking holes.

[0019] Furthermore, in the structural design of the adapter, the support mechanism provides a fixed platform for the auxiliary part through a boss arranged parallel to the support mechanism, so as to bring the auxiliary part as close to the instrument as possible, thereby enabling continuous and stable guidance and correction of the instrument with minimal space occupation.

[0020] Furthermore, the extension mechanism, with its extension locking hole located on the side perpendicular to the end of the extension support column, provides a quick and easy locking method. This simplifies the entire surgical stent installation process while ensuring reliable connection, thus reducing instrument installation and adjustment time. Furthermore, the support mechanism's design minimizes the gap between the instrument via the limiting hole and the extension mechanism, eliminating errors caused by the distance and mitigating any adverse effects of the extension mechanism on the instrument. Sliding friction is created between the rotating part and the fixing bolt and rotating fixing hole, ensuring the stability of the surgical stent during operation.

[0021] Furthermore, the design of the extension mechanism, through the T-shaped structure formed by the extension mechanism set on the top surface of the support mechanism and the connecting mechanism set on the bottom surface of the support mechanism, can improve the utilization of space while avoiding equipment interference. And through the extension mechanism set along the direction of the plumb bob, it can provide sufficient working space for guiding and correcting the instrument.

[0022] Furthermore, in the structural design of the rotating part, by setting the first and second rotating parts on both ends of the rotating arm and arranging them relatively parallel, a frame with an internal storage cavity is formed inside the rotating part. The rotation center and related fixed components can be accommodated inside the cavity, thereby achieving the function of rotation while further reducing the space occupied and improving the flexibility and applicability of the support. Moreover, by setting the corresponding instrument mounting parts in the first and second rotating parts to match the instrument, the accuracy of the instrument during installation can be ensured, and the error caused by the vibration of the instrument along the length direction during operation can be reduced, which can effectively improve the operating accuracy of the instrument.

Detailed Implementation

[0024] 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.

[0025] 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.

[0026] like Figure 1 As shown, a surgical support according to one embodiment includes: a connecting portion 10 for connecting to an external surgical platform; an adapter portion 20; one end detachably fixed to the connecting portion 10; and a rotating portion 30, including an instrument mounting portion 35 disposed on the end side. The rotating portion 30 is rotatably mounted on the adapter portion 20, and the instrument 40 is telescopically inserted through the adapter portion 20 along the travel direction of the instrument 40, and is connected in an orderly manner with the rotating portion 30. The rotating portion 30 and the adapter portion 20 are used to support and guide the selected instrument 40 to operate on the target surgical site.

[0027] One or more instrument mounting sections 35 may be provided on the end side of the rotating part 30. Thus, the instrument 40 can be pre-installed on the instrument mounting section 35 of the rotating part 30. During surgery, after the surgical support is connected to the surgical platform via the connecting part 10 and undergoes intelligent calibration, the instrument mounting section 35 is rotated by rotating the rotating part 30 to align with the adapter part 20. The formal installation is then completed based on the pre-installation. The instrument 40 passes through the adapter part 20 and is systematically connected to the rotating part 30. The rotating part 30 and the adapter part 20 work together to support and guide the movement of the instrument 40, forming multiple limiting points in the direction of travel of the instrument 40, which can effectively improve the stability of the instrument 40 during operation. If a different instrument 40 needs to be replaced, the rotating part 30 only needs to be rotated to be misaligned with the adapter 20, making it convenient for the doctor to replace the instrument 40, and then the rotating part 30 is rotated back to align with the adapter 20. Therefore, when the instrument 40 needs to be replaced later, there is no need to disassemble and recalibrate the surgical support; it can be done simply by rotating the rotating part 30.

[0028] In the above embodiments, the surgical stent utilizes the cooperation of the adapter 20 and the rotating part 30 to install the instrument 40. The rotatable design of the rotating part 30 allows the surgical stent to be connected to the surgical platform via the connecting part 10. After a single intelligent calibration, each time the instrument 40 is replaced, only the rotating part 30 needs to be rotated to align or offset from the adapter 20. This eliminates the need to disassemble and recalibrate the entire surgical stent from the surgical platform each time the instrument 40 is replaced, facilitating the surgeon's rapid assembly of the required instruments 40 during surgery. The support and guidance of the adapter 20, along with the limiting function of the rotating part 30, ensures that instruments 40 of different sizes remain in the same position after installation, ensuring that surgical electrodes can be implanted from the same location after drilling, significantly improving surgical precision. Thus, the design of the surgical stent effectively shortens surgical time and improves surgical efficiency while ensuring precision.

[0029] It should be noted that when only one instrument mounting part 35 is provided on the end side of the rotating part 30, the rotating part 30 is rotated to be misaligned with the adapter 20 each time the instrument 40 is changed, making it convenient for the doctor to change the instrument 40; in other embodiments, multiple instrument mounting parts 35 can be provided on the end side of the rotating part 30, such as Figure 1 As shown, multiple instruments 40 that are needed in the current operation can be pre-installed on different instrument mounting parts 35. When a change is needed during the operation, the doctor rotates the instrument mounting part 35 with a selected instrument 40 pre-installed to align with the adapter 20, which can more efficiently realize the flexible switching of instruments 40 at different stages of the operation and effectively shorten the operation time.

[0030] In some implementations, such as Figure 1 and Figure 2As 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.

[0031] 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.

[0032] 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.

[0033] In some implementations, such as Figure 2 and Figure 3As 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 surgical stent 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.

[0034] 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.

[0035] 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.

[0036] Optionally, the extension locking hole 213 is perpendicular to the end side of the extension support column 211 and intersects perpendicularly with the extension connection hole 212; thus, the extension locking hole 213, which is perpendicular to the end side of the extension 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.

[0037] Optional, such as Figure 2 As shown, the support mechanism 22 includes a support platform 221, a limiting through hole 222, and a rotation fixing hole 224. 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 extends through the support platform 221 along the length direction parallel to the extension mechanism 21. The rotation fixing hole 224 extends 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, which extends through the support platform 221, provides a reliable axial constraint for the instrument mounting part 35, thereby effectively eliminating the circumferential vibration of the instrument mounting part 35 during rotation, effectively ensuring the operational quality of the instrument 40. The rotation fixing hole 224, located at the end of the support platform 221 away from the extension mechanism 21, further reduces the space occupied and improves the integration of the entire surgical stent.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] Optional, such as Figure 3 As 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 surgical stent during operation.

[0043] 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.

[0044] In summary, the adapter 20 provided in the above embodiments, through the extension connection hole 212 on the boss 214 on the extension support column 211, can provide a convenient and quick installation method for the auxiliary part 50. 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 entire installation process of the surgical stent and shortens the installation and adjustment 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 surgical stent 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.

[0045] 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 application scenarios of the surgical stent.

[0046] 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.

[0047] 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.

[0048] In summary, the rotating part 30 provided in the above embodiments, through the first rotating part 32 and the second rotating part 33 arranged in parallel on both ends of the rotating arm 31, forms a frame with an internal storage cavity inside the rotating part 30. This allows the rotation center and related fixing components to be housed inside the cavity, thereby achieving rotational function while further reducing space occupation and improving the flexibility and applicability of the surgical stent. The through holes provided in the first rotating part 32 and the second rotating part 33, which correspond to each other, can ensure the accuracy of the instrument 40 during installation, reduce the error caused by the vibration of the instrument 40 along the length direction during operation, and effectively improve the operating accuracy of the instrument 40.

[0049] In some implementations, such as Figure 5As shown, to reduce errors caused by the deflection of the instrument mounting part 35 during operation, the surgical stent also includes an auxiliary part 50. One end of the auxiliary part 50 is detachably fixed to the top of the adapter part 20; the other end, which is opposite to it, extends along the length of the instrument 40 and away from the rotating part 30. Specifically, the auxiliary part 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 part 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 part 20, while the other end, which is opposite to it, extends along the length of the instrument mounting part 35 and away from the rotating part 30. The second locking mechanism 52 passes through the boss 241 at the top of the adapter part 20 and the auxiliary extension rod 51, and is lockably fixed to the adapter part 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.

[0050] Furthermore, the device 40 in this application can be the device 40 used in DBS (deep brain stimulation) surgery, or it can be one or a combination of medical devices such as a cranial drill, implantable electrode, or injection device, or it can be a surgical instrument used in other surgeries. As long as it is a surgical instrument that can be used for repeated operations on the same location, has high operational requirements, and requires rapid switching, no specific limitation is made here.

[0051] 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 40 in the length direction can be further increased, thereby effectively improving the support and calibration effect of the surgical stent on the instrument 40.

[0052] In summary, the auxiliary part 50 provided in the above embodiment can quickly and efficiently assemble and disassemble the auxiliary extension rod 51 and the adapter part 20 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.

[0053] Furthermore, in the embodiments of this application, the locking mechanism can be one or more of the following: locking bolt, hydraulic locking, pneumatic locking, and electromagnetic locking device. 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.

[0054] Furthermore, the structure of the clamping mechanism 53 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 can assist in fixing the instrument 40 and play a guiding and correcting role. The specific structure, principle, or other structural forms that achieve the same function of the clamping mechanism 53 should be easily conceived by those skilled in the art, so they will not be described in detail here.

[0055] 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.

[0056] The surgical stent provided in the above embodiments of this application has at least the following characteristics: (1) 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.

[0057] (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 under the action of the extension locking hole 213, a reliable and stable connection is achieved; 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 2 The extension mechanism 21 can minimize the gap between the instrument 40 and the extension mechanism 21, improve the coaxiality between the instrument 40 and the extension mechanism 21, 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 installation and operation of the instrument 40. The design of the fixing mechanism 24 forms sliding friction between the rotating part 30 and the fixing bolt 241 and the rotating fixing hole 224, thereby ensuring the stability of the surgical support 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 without equipment interference. The extension mechanism 21, which extends along the plumb line, can provide sufficient guiding and corrective working space for the instrument 40.

[0058] (3) 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 components inside the cavity. This achieves the function of rotation while further reducing the space occupied and improving the flexibility and applicability of the surgical stent. 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.
