[0039] Figure 1 This is a schematic diagram of the structure of a surgical guide device provided in an embodiment of this application. Figure 2 This is a structural schematic diagram of a surgical guide device in use according to an embodiment of this application.
[0040] Please see Figure 1 and Figure 2An embodiment of the first aspect of this application provides a surgical guide device, which includes a base 000, a positioning component 700, and an adjustment component 200. The base 000 has a support surface 001 and a clamping component 100. The clamping component 100 includes a first clamping portion 120 and a second clamping portion 130 spaced apart along a first direction X on the support surface 001, the first clamping portion 120 and the second clamping portion 130 enclosing a clamping space 110. The adjustment component 200 is connected to the side of the second clamping portion 130 away from the first clamping portion 120. The adjustment component 200 includes a first end M and a second end N disposed opposite to each other along the first direction X. The first end M is rotatably disposed relative to the second clamping portion 130 so that the second end N can deflect in a direction closer to or farther from the support surface 001. The positioning component 700 is detachably connected to the clamping component 100. One end of the positioning component 700 is located in the clamping space 110, and the other end extends in a direction away from the first clamping part 120. The positioning component 700 also includes a clearance hole 710, which is used to avoid at least part of the adjusting component 200.
[0041] In the embodiments provided in this application, the surgical guide device includes a base 000, a positioning component 700, and an adjustment component 200. The base 000 has a support surface 001 and a clamping component 100. The support surface 001 is used to arrange the clamping component 100. The clamping component 100 is used to clamp the positioning component 700 and includes a first clamping portion 120 and a second clamping portion 130 spaced apart along a first direction X on the support surface 001. The first clamping portion 120 and the second clamping portion 130 enclose a clamping space 110 to restrict the movement of the positioning component 700. The adjusting component 200 is used to place the surgical instrument 002. The adjusting component 200 is connected to the side of the second clamping part 130 away from the first clamping part 120. The adjusting component 200 includes a first end M and a second end N disposed opposite to each other along a first direction X. The first end M is rotatably disposed relative to the second clamping part 130, so that the second end N can deflect in a direction closer to or farther from the support surface 001, thereby adjusting the angle of the surgical instrument 002 for multi-directional guidance during surgery. The positioning component 700 is used to position the area to be operated on and is detachably connected to the clamping component 100. One end of the positioning component 700 is located in the clamping space 110, and the other end extends in a direction away from the first clamping part 120, allowing the operator to accurately move the adjusting component 200 to the area to be operated on after obtaining the position of the area to be operated on. The positioning component 700 also includes a clearance hole 710, which is used to avoid at least part of the adjusting component 200, so that the adjusting component 200 can rotate on the side of the positioning component 700 facing the support surface 001, thus limiting the rotation angle of the adjusting component 200. In this embodiment, by deflecting the second end N of the adjusting component 200 in a direction closer to or further away from the support surface 001, the angle of the surgical instrument 002 can be adjusted, allowing for multi-directional guidance of the surgical instrument 002 during surgery, making the surgery more precise and adaptable to different surgical scenarios.
[0042] Optionally, the surgical guide device provided in this application embodiment can be used in spinal surgery, trauma surgery, and other surgeries to assist operators in accurately completing the surgery.
[0043] Optionally, the surgical guide device may also include a connecting structure 600, one end of which may be fixedly connected to the side of the tracer 500 away from the clamping component 100, and the other end of which may be connected to the robotic arm of the surgical robot, thereby driving the surgical guide device to move.
[0044] Optional, such as Figure 2 As shown, the positioning component 700 can be a target plate, which is a positioning and guiding tool in surgery. The target plate has preset markers or channels, which can be clearly displayed in the intraoperative imaging instrument to help the operator accurately locate the specific segment of the spine or the lesion area.
[0045] Optionally, the surgical instrument 002 can be a guide needle or a drill bit. The surgical instrument 002 is fitted inside the adjustment component 200 so that the drug or instrument can be accurately delivered to the predetermined target area.
[0046] Optionally, the adjusting component 200 can be a sleeve, and the surgical instrument 002 is fitted inside the sleeve to achieve precise guidance.
[0047] Optional, such as Figure 1 and Figure 2 As shown, the support surface 001 is spaced apart from the edge of the second direction Y and the second clamping portion 130, so that a clearance space 003 communicating with the clamping space 110 is formed on at least one side of the second clamping portion 130 along the second direction Y. At least a portion of the positioning component 700 near the clamping component 100 contacts and connects with the support surface 001 in the clearance space 003, which increases the contact area between the positioning component 700 and the support surface 001, improves the support effect of the base 000 on the positioning component 700, and further restricts the movement of the positioning component 700, wherein the first direction X intersects with the second direction Y.
[0048] Optionally, the positioning component 700 further includes a stop 720, which is located on the side of the clearance hole 710 opposite to the clamping component 100 and abuts against the second end N of the adjusting component 200, allowing the adjusting component 200 to rotate on the side of the positioning component 700 facing the support surface 001 via the stop 720. During rotation, the side of the adjusting component 200 opposite to the second clamping part 130 will not rotate beyond the side of the support surface 001 opposite to the base 000, thus improving the problem of excessive rotation of the adjusting component 200 during surgery, which affects surgical efficiency.
[0049] Optionally, the positioning component 700 also includes a weight reduction hole located on the side of the stop portion 720 opposite to the clearance hole 710, which can reduce the weight of the positioning component 700.
[0050] In some alternative embodiments, such as Figure 3 and Figure 4 As shown, the surgical guide device also includes a rotating part 300 and a rotating shaft 400. The rotating part 300 is fixedly connected to the side of the second clamping part 130 away from the first clamping part 120, and the rotating part 300 includes a through hole 310. The rotating shaft 400 is sleeved in the first through hole 310, and the adjusting component 200 is fixedly connected to the rotating shaft 400 and rotatably disposed relative to the rotating part 300 via the rotating shaft 400.
[0051] In these optional embodiments, the adjusting component 200 can be rotated via the pivot 400, thereby enabling multi-angle adjustment of the adjusting component 200. The angle of the adjusting component 200 can be adjusted as needed to adapt to different surgical sites and operational requirements. Furthermore, the rotation of the adjusting component 200 can be achieved without complex disassembly and assembly steps, saving surgical time and reducing operational difficulty.
[0052] Optional, such as Figure 4 and Figure 5 As shown, a protrusion 401 is provided on one side of the rotating shaft 400, and a snap-fit part 201 is provided on one side of the adjusting component 200. The snap-fit part 201 includes a through hole 202. The protrusion 401 is fixedly sleeved in the second through hole 202. The rotating shaft 400 and the adjusting component 200 are fixedly connected through the protrusion 401 and the snap-fit part 201, and the connection is stable.
[0053] Optionally, the cross-section of the protrusion 401 can be polygonal, and the shape of the second through hole 202 can be adapted to the protrusion 401, thereby reducing the possibility of relative rotation between the protrusion 401 and the second through hole 202, and further improving the rotation accuracy of the adjustment component 200.
[0054] Optionally, the locking part 201 also includes a scale 203 surrounding the second through hole 202, which can provide a precise positioning reference. Using the scale 203, the operator can more accurately adjust the angle during the adjustment of the adjusting component 200, while also clearly seeing the current adjustment status, ensuring the smooth progress of the surgery.
[0055] In some alternative embodiments, such as Figures 3 to 5 As shown, the rotating part 300 also includes a through groove 320 and a fixing part 330 disposed in the through groove 320. The through groove 320 is connected to the first through hole 310. The fixing part 330 is movably disposed along the extending direction of the through groove 320 so that the fixing part 330 can fix the rotating shaft 400 when it is close to the rotating shaft 400.
[0056] In these optional embodiments, the fixing part 330 is movably disposed along the extension direction of the through groove 320, which can lock the rotating shaft 400 to keep the adjusting member 200 at the required angle and prevent further rotation. This improves the problem of unnecessary injury to the patient due to excessive rotation of the rotating shaft 400 and improves the stability of the entire surgical guide device during the operation. For example, when it is necessary to adjust the angle of the adjusting member 200, the fixing part 330 can be moved away from the rotating shaft 400, thereby loosening the fixing part 330 from the rotating shaft 400 and adjusting the angle of the adjusting member 200. When the adjusting member 200 is adjusted to the appropriate angle, the fixing part 330 is moved closer to the rotating shaft 400 to lock the fixing part 330 from the rotating shaft 400, thereby limiting the further rotation of the adjusting member 200 and facilitating the operation. The locking function of the fixing part 330 from the rotating shaft 400 reduces the possibility of accidental loosening of the adjusting member 200 during the operation, further improving the safety of the operation.
[0057] Optionally, the fixing part 330 can be a bolt, and the through groove 320 is provided with threads that mate with the bolt. By rotating the bolt, the adjusting part 200 can be locked and rotated, and the bolt is also prevented from falling out of the through groove 320 when it is not tightened, thus avoiding interference with the operation. Optionally, a nut 333 can also be provided on the side of the bolt away from the rotating shaft 400. The nut 333 is rotatably connected to the bolt. By rotating the nut 333, the bolt can be moved along the extension direction of the through groove 320, thereby achieving the locking and rotation of the adjusting part 200.
[0058] Optionally, the rotating part 300 also includes a mounting through hole 370 which is disposed opposite to the through groove 320 on both sides of the first through hole 310 and communicates with the first through hole 310. The fixing part 330 is inserted into the through groove 320 through the mounting through hole 370, and at least part of the fixing part 330 extends out of the through groove 320 toward the side away from the rotating shaft 400, so as to facilitate the installation of the fixing part 330 and the nut 333.
[0059] In some optional embodiments, the through groove 320 includes a first sub-groove 321 and a second sub-groove 322 that are interconnected. The inner diameter of the first sub-groove 321 is smaller than the inner diameter of the second sub-groove 322. The first sub-groove 321 is located on the side of the second sub-groove 322 away from the rotating shaft 400. The fixing part 330 includes a first sub-part 331 and a second sub-part 332 that are interconnected. The cross-sectional area of the end 332a of the second sub-part 332 near the first sub-part 331 is larger than the cross-sectional area of the first sub-part 331. The second sub-part 332 is located in the second sub-groove 322. The fixing part 330 is movably disposed between a first position and a second position. In the first position, at least a portion of the first sub-part 331 is located in the second sub-groove 322 and the second sub-part 332 is engaged with the rotating shaft 400. In the second position, the first sub-part 331 is located on the side of the second sub-groove 322 away from the rotating shaft 400.
[0060] In these optional embodiments, the fixing part 330 is movably disposed between a first position and a second position, wherein in the first position the fixing part 330 is engaged with the rotating shaft 400, and in the second position the rotating shaft 400 is rotatable. The inner diameter of the first sub-groove 321 is smaller than the inner diameter of the second sub-groove 322, and the cross-sectional area of the end 332a of the second sub-part 332 near the first sub-part 331 is larger than the cross-sectional area of the first sub-part 331, thereby allowing the second sub-part 332 to be confined within the second sub-groove 322, improving the problem of the fixing part 330 being completely removed from the through groove 320 during surgery, causing the fixing part 330 to fall off and leading to surgical interruption or failure.
[0061] In some alternative embodiments, the pivot 400 is provided with a plurality of ball sockets 410 spaced apart circumferentially, and the second sub-part 332 includes an arc surface 332b at one end facing the pivot 400. In a first position, the arc surface 332b engages with one of the plurality of ball sockets 410.
[0062] In these optional embodiments, since the rotating shaft 400 is provided with multiple ball sockets 410, the arc surface 332b of the second sub-part 332 can engage with any one of the ball sockets 410, thereby achieving precise fixation at multiple angles. Simultaneously, the multiple ball sockets 410 design provides more fixing points, increasing the flexibility of the adjusting component 200. The snap-fit design between the arc surface 332b and the ball sockets 410 allows the fixing part 330 to be more securely fixed and engaged with the rotating shaft 400 in the first position, improving the problem of the fixing part 330 loosening due to vibration or other external forces during surgery, and enhancing the stability of the surgery.
[0063] In some optional embodiments, the rotating part 300 includes a groove 340, which is connected to the first through hole 310. The groove 340 and the through groove 320 are distributed circumferentially along the rotating shaft 400. A first reset member 350 is provided in the groove 340. The first reset member 350 is telescopically arranged along the extending direction of the groove 340 so that the first reset member 350 can provide a clamping force to the rotating shaft 400.
[0064] In these optional embodiments, the first reset member 350 is telescopically extendable along the extension direction of the groove 340. The rotating shaft 400 can abut against the first reset member 350 and compress the first reset member 350. The first reset member 350 then provides a clamping force to the rotating shaft 400, limiting the rotating shaft 400 and improving the stability of the operation. At the same time, during the adjustment process, before the fixing part 330 is locked with the rotating shaft 400, the first reset member 350 can initially lock and limit the rotating shaft 400, making the rotating shaft 400 rotate more slowly.
[0065] In some alternative embodiments, the first reset member 350 includes a first elastic member 351 and a first ball 352. The first elastic member 351 is telescopically oriented along the extension direction of the groove 340, and the first ball 352 engages with one of the remaining ball sockets 410.
[0066] In these optional embodiments, the first elastic element 351 is telescopically oriented along the extension direction of the groove 340. During the adjustment process, before the fixing part 330 is locked with the rotating shaft 400, the first ball 352 can flexibly engage with the ball socket 410 on the rotating shaft 400 to initially limit the rotating shaft 400, so that the fixing part 330 can be more accurately aligned with the position of the other ball sockets 410, thereby ensuring the reliability of locking.
[0067] Optionally, the rotating part 300 also includes mounting through holes 370 disposed opposite to the groove 340 and extending through both sides of the first through hole 310, to facilitate the installation of the first elastic member 351 and the first ball 352.
[0068] In some alternative embodiments, such as Figure 1 and Figure 2 As shown, the second clamping part 130 includes an arc-shaped convex surface 132 on the side facing the clamping space 110. The arc-shaped convex surface 132 protrudes towards the first clamping part 120, and the clearance hole 710 includes an arc-shaped inner wall surface 711 on the side near the first clamping part 120. The arc-shaped inner wall surface 711 and the arc-shaped convex surface 132 cooperate with each other.
[0069] In these alternative embodiments, the arcuate convex surface 132 is adapted to the shape of the arcuate inner wall surface 711, and the arcuate convex surface 132 and the first clamping part 120 contact the arcuate inner wall surface 711 to form a multi-point positioning structure for fixing, so that the positioning part 700 is stably clamped in the clamping space 110.
[0070] Optionally, there can be two arc-shaped convex surfaces 132 and two arc-shaped inner wall surfaces 711. The second clamping part 130 includes a wall part 131 on the side facing the clamping space 110. The two arc-shaped convex surfaces 132 are spaced apart on both sides of the wall part 131. The shapes of the two arc-shaped convex surfaces 132 and the two arc-shaped inner wall surfaces 711 are adapted to each other, so that there are more contact points and the positioning part 700 is clamped more stably in the clamping space 110.
[0071] In some alternative embodiments, such as Figures 1 to 3As shown, the first clamping part 120 includes a locking groove 150 with an opening facing the clamping space 110. A second reset member 140 is disposed in the locking groove 150. The second reset member 140 is telescopically disposed between a third position and a fourth position along the first direction X. In the third position, at least a portion of the second reset member 140 protrudes from the first clamping part 120, and the minimum distance between the second reset member 140 and the second clamping part 130 in the third position is less than the minimum distance between the second reset member 140 and the second clamping part 130 in the fourth position.
[0072] And / or, the second clamping part 130 includes a locking groove 150 with an opening facing the clamping space 110, and a second reset member 140 is disposed in the locking groove 150. The second reset member 140 is telescopically disposed between a third position and a fourth position along a first direction X. In the third position, at least a portion of the second reset member 140 protrudes from the second clamping part 130, and the minimum distance from the second reset member 140 to the first clamping part 120 in the third position is less than the minimum distance from the second reset member 140 to the first clamping part 120 in the fourth position.
[0073] In these optional embodiments, the locking groove 150 can be disposed on the first clamping part 120, the second clamping part 130, or both the first clamping part 120 and the second clamping part 130. The position of the locking groove is not limited and depends on the specific situation. For ease of understanding, the embodiments in this application are described with the locking groove 150 disposed on the first clamping part 120.
[0074] When the second reset member 140 is in the third position, at least a portion of the second reset member 140 protrudes from the first clamping portion 120, and the second reset member 140 is in a relaxed state. The minimum distance between the second reset member 140 and the second clamping portion 130 is less than the minimum distance between the second reset member 140 and the second clamping portion 130 in the fourth position, so that the second reset member 140 is compressed when changing from the third position to the fourth position. In the fourth position, the second reset member 140 abuts against the positioning member 700 and is at least partially pressed into the locking groove 150. The positioning member 700 squeezes the second reset member 140 and generates a rebound force, further locking the positioning member 700. This facilitates the positioning and placement of the positioning member 700, and makes adjustment and operation convenient.
[0075] Optionally, the second reset member 140 includes a second elastic member 141 and a second ball bearing 142, with the second ball bearing 142 located on the side of the second elastic member 141 near the second clamping portion 130. In the third position, at least a portion of the second ball bearing 142 is located in the clamping space 110, at which point the second elastic member 141 is in a relaxed state. At least a portion of the positioning member 700 is clamped in the clamping space 110, and the second ball bearing 142 abuts against the positioning member 700 and is at least partially pressed into the locking groove 150. The positioning member 700 compresses the second ball bearing 142 and generates a rebound force, further locking the positioning member 700. The contact between the second ball bearing 142 and the positioning member 700 is a point contact. Due to the very small contact area, the rebound force per unit area increases, further improving the clamping stability.
[0076] Optionally, the first clamping part 120 and the second clamping part 130 that does not have a locking groove 150 may have a groove, which can reduce the weight of the surgical guide device.
[0077] In some alternative embodiments, such as Figure 1 and Figure 2 As shown, the surgical guide device also includes a tracer component 500, which includes a mounting part 510 and a locator 520. The mounting part 510 is fixed to the side of the first clamping part 120 away from the second clamping part 130, and a plurality of locators 520 are arranged at intervals around the mounting part 510.
[0078] In these optional embodiments, the locator 520 is used to identify the spatial position of the end effector in different surgical scenarios. Multiple locators 520 are arranged at intervals around the mounting part 510, which can perform tracking and positioning at different angles, making the positioning more accurate and reliable and improving the success rate of surgery.
[0079] Optionally, the tracer component 500 also includes multiple mounting surfaces spaced apart around the mounting portion 510, and multiple locators 520 spaced apart on the mounting surfaces to achieve multi-directional positioning of the surgical guide device.
[0080] Optionally, the locator 520 can be a tracer, which provides the device's location information (e.g., captured by infrared navigation). When taking an X-ray, subsequent image registration can be performed based on the positions marked on the X-ray and the location information of the tracer captured by the navigator.
[0081] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
