When different instruments are required for the same surgical site, the different instruments need to be positioned at the same site. The prior art generally positions the positioning channel first, and then inserts adapters with different inner hole sizes into the positioning channel to clamp surgical instruments of different diameters.

A guide device 10 provided in an embodiment of the present invention comprises a bracket 100, a positioning assembly 200 and a limiting assembly 300; the positioning assembly 200 comprises a clamping member 250, the clamping member 250 is rotatably connected to the bracket 100 around a first axis 410, the clamping member 250 is provided with a plurality of mounting holes 230 of different sizes around the circumference, each mounting hole 230 is used for passing instruments 500 of different sizes, the center line of each mounting hole 230 is equidistant from the first axis 410 and is parallel to the first axis 410. At least part of the hole wall of each mounting hole 230 is configured to abut against the corresponding instrument 500 for fixing the corresponding instrument 500 so that the center line of the instrument 500 passing through the mounting hole 230 coincides with the center line of the corresponding mounting hole 230; the limiting component 300 is connected to the bracket 100, and the limiting component 300 can abut against the positioning component 200 to limit the rotation of the clamping member 250, so as to position the center line of the instrument 500 passing through the mounting hole 230 at the target position.

[0050] The guide device 10 in the present application is applied to the guide device. The guide device also includes a posture adjustment device 20, which is connected to the guide device 10. The posture adjustment device 20 is used to drive the guide device 10 to move to adjust the position of the guide device 10, so as to accurately align the surgical instrument 500 fixed on the guide device 10 to the surgical site. In the prior art, different adapters need to be replaced for different surgical instruments 500, which involves the disassembly and installation of some parts, resulting in low efficiency in positioning the instrument 500 and affecting the efficiency of the surgery.

[0051] Specifically, the present application provides a plurality of mounting holes 230 of different sizes on the clamping member 250, and at least part of the hole wall of each mounting hole 230 can abut against the corresponding instrument 500, so that instruments 500 of different sizes can be stably fixed in the corresponding mounting holes 230, so that the center lines of the instruments 500 of different sizes coincide with the center lines of the corresponding mounting holes 230, and the center lines of each mounting hole 230 are equidistant from the first axis 410 and are parallel to the first axis 410. If the center line of one of the mounting holes 230 is defined as the target position, then during the process of the clamping member 250 rotating relative to the bracket 100 around the first axis 410, the center lines of each mounting hole 230 can be rotated to the target position, so that the center line of the instrument 500 inserted in the mounting hole 230 can be rotated to the target position to accurately align with the surgical site, and the rotation of the positioning assembly 200 is limited by the limit assembly 300, so that the instrument 500 is stably positioned at the target position, facilitating surgery. Compared with the prior art, in the present application, when replacing instruments 500 of different sizes, there is no need to replace parts and reposition the guide device 10, which reduces the work of disassembly, installation and positioning adjustment and improves surgical efficiency.

[0052] It should be noted that before the surgical preparation, the guide device 10 will be adjusted by the posture adjustment device 20 so that the center line of the instrument 500 inserted into the preset installation hole 230 can be aligned with the surgical site, and the position of the center line of the preset installation hole 230 is defined as the target position. Since the structures of the action ends of different instruments 500 may be different, this embodiment uses the center line of each instrument 500 as the standard, that is, when the center line of the instrument 500 is at the target position, it can be regarded that the instrument 500 is aligned with the surgical site.

[0053] See also Figure 1 and Figure 5 , Figure 5Partial exploded view of a clamping member in a guide device provided in one embodiment of the present invention. In one embodiment, the clamping member 250 includes a rotating disk 210 and a limiting sleeve 220, the rotating disk 210 is provided with a plurality of mounting grooves 211 around the circumference, the groove wall of each mounting groove 211 is provided with a first notch 214 for the instrument 500 to extend into, the limiting sleeve 220 is sleeved on the rotating disk 210 and can cover the first notch 214 of each mounting groove 211, and the groove wall of each mounting groove 211 and a portion of the limiting sleeve 220 together constitute the hole wall of each mounting hole 230.

[0054] Specifically, the mounting groove 211 has openings on both sides along the extension direction of the first axis 410 for the instrument 500 to pass through. The first slot 214 on the slot wall of the mounting groove 211 is arranged to facilitate the insertion of each instrument 500, and the first slot 214 of each mounting groove 211 is blocked by the limiting sleeve 220 sleeved on the turntable 210 to limit the escape of the instrument 500 passing through the mounting hole 230, so that the instrument 500 is stably fixed in the mounting hole 230, thereby improving the adaptability of the guide device 10.

[0055] Furthermore, the first slot 214 of each mounting slot 211 is disposed on a side of the slot wall of the corresponding mounting slot 211 away from the first axis 410 , thereby shortening the path for the device 500 to extend into the mounting slot 211 and improving the efficiency of positioning the device 500 .

[0056] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the limiting sleeve 220 is rotatably connected to the turntable 210 around the second axis 430, the second axis 430 is parallel to and relatively spaced from the first axis 410, and an inlet 221 is provided on one side of the limiting sleeve 220, and the inlet 221 can be connected to a first slot 214 of a mounting slot 211 for the instrument 500 to extend into.

[0057] Specifically, since the second axis 430 is parallel to the first axis 410, and the entrance 221 is connected to the first slot 214 of a mounting groove 211, when the limit sleeve 220 rotates relative to the turntable 210 around the second axis 430, the entrance 221 rotates relative to the turntable 210 around the second axis 430, so that the entrance 221 can correspond one-to-one with the first slot 214 of each mounting groove 211, thereby facilitating the insertion of instruments 500 of different sizes from each entrance 221 and entering the mounting groove 211 from the first slot 214 of the corresponding mounting groove 211.

[0058] When the center line of the instrument 500 is aligned with the surgical site, the limiting sleeve 220 is controlled to rotate relative to the turntable 210 around the second axis 430 so that the inlet 221 is connected to the first notch 214 of the mounting slot 211 at the target position, and the guide device 10 can be withdrawn from the side, and the instrument 500 is left at the target position, thereby facilitating the operation of the instrument 500 and improving the surgical efficiency. In addition, when the instrument 500 needs to be replaced or disassembled, the instrument 500 can be withdrawn from the side, improving the efficiency of the guide device 10 in positioning the instrument 500.

[0059] Furthermore, the second axis 430 coincides with the axis of the turntable 210 and is spaced from the first axis 410. Therefore, during the rotation of the turntable 210 relative to the bracket 100, the limit sleeve 220 rotates synchronously with the turntable 210. During the rotation of the limit sleeve 220 relative to the turntable 210, since the rotation axis of the turntable 210 does not coincide with the rotation axis of the limit sleeve 220, the rotation of the turntable 210 is restricted, thereby reducing interference with the turntable 210, so that the mounting holes on the turntable 210 can be stably maintained in the current position, thereby improving the adaptability of the guide device 10.

[0060] Furthermore, the size of the entrance 221 is not less than the size of the first slot 214 corresponding to the largest mounting slot 211 on the turntable 210, thereby avoiding interference when the instrument 500 is inserted into the first slot 214, and improving the adaptability of the guide device 10. Preferably, the size of the entrance 221 is the same as the size of the first slot 214 corresponding to the largest mounting slot 211 on the turntable 210.

[0061] In other embodiments, the limiting sleeve 220 is detachably arranged relative to the turntable 210 , and the device 500 is first inserted into the installation slot 211 , and then the limiting sleeve 220 is sleeved on the turntable 210 to limit the device 500 .

[0062] See also Figure 1 and Figure 5 In one embodiment, the positioning assembly 200 also includes a fastener 222, which is passed through the limiting sleeve 220 and abuts against the turntable 210, and the fastener 222 is threadedly connected to the limiting sleeve 220. The fastener 222 is configured to be able to rotate relative to the limiting sleeve 220 so as to abut against the turntable 210 to limit the rotation of the limiting sleeve 220 relative to the turntable 210.

[0063] Specifically, the fastener 222 is threadedly connected to the limiting sleeve 220, and one end of the fastener 222 that passes through the limiting sleeve 220 abuts against the turntable 210. By rotating the fastener 222, the fastener 222 moves relative to the turntable 210, thereby increasing the abutting force of the fastener 222 on the turntable 210, thereby increasing the friction force and limiting the rotation of the limiting sleeve 220 relative to the turntable 210. When the limiting sleeve 220 blocks the first notch 214 located at the target position, the limiting sleeve 220 is limited from rotating relative to the turntable 210 by rotating the fastener 222, so that the limiting sleeve 220 can stably block the first notch 214 located at the target position, thereby preventing the instrument 500 from falling out of the corresponding first notch 214, and improving the stability of the guide device 10. Preferably, the fastener 222 extends along the radial direction of the turntable 210.

[0064] Furthermore, a protrusion 223 is convexly provided on the side of the limiting sleeve 220 away from the rotating disk 210 , and the fastener 222 is passed through the protrusion 223 and is threadedly connected to the limiting sleeve 220 , thereby increasing the stability of the connection between the fastener 222 and the limiting sleeve 220 .

[0065] Furthermore, an operating end 224 is provided on the side of the fastener 222 away from the turntable 210, and a plurality of first grooves 225 are circumferentially spaced on the operating end 224, so that when the operating end 224 is manually rotated to control the rotation of the fastener 222, friction can be increased, thereby facilitating the control of the rotation of the fastener 222.

[0066] See also Figure 1 , Figure 3 and Figure 4 , Figure 5 A top view of the cooperation between the stop sleeve and the turntable in the guide device provided in one embodiment of the present invention. In one embodiment, each mounting groove 211 includes a first side wall 212, and the first side wall 212 is used to abut against the instrument 500 penetrated in the mounting hole 230. Each first side wall 212 is an arc, and the center of each arc falls on the center line of the corresponding mounting hole 230. The distance between the stop sleeve 220 and the center of each arc is equal to the radius of the corresponding arc. The stop sleeve 220 is used to cooperate with the first side wall 212 to clamp the corresponding instrument 500.

[0067] Specifically, at least part of each device 500 is a cylindrical section, and the cylindrical section of the device 500 is partially inserted into the mounting hole 230, and a circular contour line 420 is formed in the extension direction of the first axis 410, and the center of the contour line 420 falls on the center line of the corresponding mounting hole 230. Since the center line of the device 500 coincides with the center line of the corresponding mounting hole 230, and the center of each arc falls on the center line of the corresponding mounting hole 230, the center of each contour line 420 coincides with the center of the corresponding first side wall 212, and the outer periphery of part of the cylindrical section of the device 500 fits the first side wall 212. At the same time, the limiting sleeve 220 is tangent to the circle formed by the center of each arc, that is, the limiting sleeve 220 and the contour line 420 of the instrument 500, so that the area corresponding to the limiting sleeve 220 and the first slot 214 can abut against the instrument 500, thereby cooperating with the first side wall 212 to stably clamp the instrument 500 and improve the accuracy of the guide device 10 in accurately positioning the instrument 500.

[0068] Among them, on a plane perpendicular to the first axis 410, a pitch circle 217 is made with the position of the first axis 410 as the center and the distance from the center line of the mounting groove 211 to the first axis 410 as the radius, and the center of the arc formed by each first side wall 212 falls on the pitch circle 217, so that during the rotation of the turntable 210 around the first axis 410, the center line of each mounting hole 230 can be rotated to the target position.

[0069] It should be noted that after the instrument 500 is inserted into the mounting groove 211 at the target position from the entrance 221 side of the limiting sleeve 220, the limiting sleeve 220 is rotated so that the limiting sleeve 220 blocks the entrance 221 and cooperates with the first side wall 212 to clamp the instrument 500. At this time, since the friction resistance to the instrument 500 is small, the instrument 500 can be manually pushed to move along the extension direction of the mounting hole 230, thereby playing a guiding role and further assisting the doctor to position the instrument 500 at the surgical site. After the position of the instrument 500 in the extension direction along the first axis 410 is determined, the fastener 222 can be adjusted to tighten the limiting sleeve 220 against the instrument 500, thereby stably limiting the movement of the instrument 500.

[0070] See also Figure 1 and Figure 4 In one embodiment, each mounting slot 211 further includes two second side walls 213 , and both ends of each first side wall 212 are connected to a second side wall 213 for guiding the instrument 500 to extend into each mounting slot 211 .

[0071] Furthermore, each first side wall 212 has a π radian, thereby increasing the contact area between the first side wall 212 and the instrument 500 and improving the stability of clamping the instrument 500 without affecting the insertion of the instrument 500 into the first slot 214 .

[0072] Furthermore, the second side wall 213 is tangent to the arc formed by the first side wall 212, that is, the mounting groove 211 is U-shaped, thereby reducing the circumferential size of the mounting groove 211 in the turntable 210, and more mounting grooves 211 of different sizes can be arranged on the turntable 210 to adapt to more instruments 500, thereby improving the adaptability of the guide device 10.

[0073] See also Figure 1 and Figure 6 , Figure 6 A partial exploded view of a guide device provided in one embodiment of the present invention. In one embodiment, the positioning assembly 200 further includes a rotating member 240, the rotating member 240 is connected to the clamping member 250, the bracket 100 is provided with a connecting hole 111, the rotating member 240 is passed through the connecting hole 111, and is connected to the bracket 100 for rotation around the first axis 410, and the limiting assembly 300 is used to abut against the rotating member 240 to limit the rotation of the clamping member 250.

[0074] Specifically, by setting the rotating member 240, the positioning assembly 200 is stably rotationally connected to the bracket 100, and the limiting assembly 300 abuts against the rotating member 240, which can reduce the interference with the relative position of the limiting sleeve 220 and the turntable 210 and improve the stability of the guide device 10.

[0075] See also Figure 1 and Figure 6 In one embodiment, the clamping member 250 is provided with a special-shaped hole 216 penetrating along the extension direction of the first axis 410, the rotating member 240 is inserted into the special-shaped hole 216, and at least one end extends out of the special-shaped hole 216, and is rotatably connected to the bracket 100. The rotating member 240 is configured to be able to rotate around the first axis 410 relative to the bracket 100 to drive the clamping member 250 to rotate synchronously.

[0076] Specifically, the special-shaped hole 216 is provided on the rotating disk 210, and the rotating member 240 is in a shape matching the special-shaped hole 216. The rotating member 240 is slidably connected with the hole wall of the special-shaped hole 216 along the extension direction of the first axis 410, so that when the rotating member is rotated relative to the bracket 100, the clamping member 250 can be driven to rotate synchronously to adjust the position of the mounting hole 230. In this embodiment, the arrangement of the rotating member 240 inserted into the clamping member 250 facilitates the disassembly and installation of the clamping member 250 relative to the bracket 100, thereby facilitating the replacement of the clamping member 250 and improving the adaptability of the guide device 10. Among them, the projection of the special-shaped hole 216 in the extension direction of the first axis 410 is a non-circular pattern such as a triangle, a quadrilateral, an ellipse, etc.

[0077] See also Figure 1 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 , Figure 7 for Figure 6 The large picture of the hair at A in the middle; Figure 8 yes Figure 1 The enlarged view of point B in the middle; Fig. 9 yes Figure 3 Enlarged view of point C in the middle. In one embodiment, the positioning assembly 200 further includes a matching disk 242, which is connected to the portion of the rotating member 240 extending outside the connecting hole 111, and the matching disk 242 abuts against the side of the bracket 100 away from the clamping member 250; the limiting assembly 300 further includes a abutting end 323, which is configured to abut against the side of the matching disk 242 away from the clamping member 250 when the limiting assembly 300 limits the clamping member 250 to rotate relative to the bracket 100, so as to limit the rotating member 240 from coming out relative to the clamping member 250.

[0078] Specifically, when the limit assembly 300 limits the rotation of the clamping member 250 relative to the bracket 100, the abutting end 323 abuts against the side of the mating disk 242 away from the clamping member 250, and a force is applied to the rotating member 240 toward the clamping member 250, while the mating disk 242 abuts against the side of the bracket 100 away from the clamping member 250, thereby limiting the displacement of the rotating member 240 in the extension direction of the first axis 410, so that the rotating member 240 is stably inserted into the special-shaped hole 216 and stably connected to the clamping member 250, thereby improving the adaptability of the guide device 10.

[0079] The matching disk 242 can be sleeved and connected to the rotating member 240 , or can be integrally formed with the rotating member 240 , as long as the positions of the matching disk 242 and the rotating member 240 in the extension direction of the first axis 410 are fixed.

[0080] Furthermore, the connection hole 111 is a circular hole, the outer contour of the rotating member 240 is D-shaped, and the arc segment of the rotating member 240 is slidably connected to a part of the hole wall of the connection hole 111, so that the rotating member 240 and the bracket 100 are stably rotationally connected.

[0081] In other embodiments, the rotating member 240 includes a cylindrical section and a special-shaped section connected to each other, the special-shaped section is used to cooperate with the special-shaped hole 216, and the cylindrical section is used to cooperate with the connecting hole 111 and is rotatably connected to the hole wall of the connecting hole 111.

[0082] See also Figure 1 and Figure 6 In one embodiment, an operating portion 243 is further provided on the rotating member 240. The operating portion 243 is located on the side of the matching disk 242 away from the turntable 210. A plurality of second grooves 244 are circumferentially provided on the operating portion 243. Therefore, when the operating portion 243 is manually rotated to control the rotating member 240 to drive the turntable 210 to rotate, the friction force can be increased, thereby facilitating the control of the rotation of the rotating member 240.

[0083] See also Figure 1 and Figure 6 In one embodiment, the bracket 100 includes a first support plate 110, a second support plate 150 and a third support plate 160. The first support plate 110 and the second support plate 150 are spaced apart along the extension direction of the first axis 410 and are both connected to the third support plate 160. The clamping member 250 is located between the first support plate 110 and the second support plate 150 and abuts against the first support plate 110 and the second support plate 150 respectively.

[0084] Specifically, at least one of the first support plate 110 and the second support plate 150 is provided with a connection hole 111, and abuts against the matching disk 242. The first support plate 110 and the second support plate 150 abut against both ends of the clamping member 250, respectively, so as to limit the movement of the clamping member 250 along the extension direction of the first axis 410, and then through the limiting assembly 300, the clamping member 250 can be stably maintained at the current position, ensuring the stability of the clamping member 250 in positioning the device 500.

[0085] Furthermore, the first support plate 110 and the second support plate 150 are both provided with connection holes 111, and both ends of the rotating member 240 extend out of the special-shaped hole 216 and are rotatably connected to the first support plate 110 and the second support plate 150, thereby improving the stability of the connection between the clamping member 250 and the bracket 100.

[0086] See also Figure 1 , Figure 2 and Figure 6In one embodiment, the first support plate 110 and the second support plate 150 cover at least a portion of each mounting hole 230, and the first support plate 110 and the second support plate 150 are both provided with an avoidance groove 140, and the avoidance groove 140 is used to avoid the device 500 passing through the mounting hole 230 located at the target position.

[0087] Specifically, the avoidance groove 140 is set at the target position. The first support plate 110 and the second support plate 150 cover at least part of each mounting hole 230, increasing the contact area between the first support plate 110 and the second support plate 150 and the clamping member 250, thereby improving the support and limiting effect on the clamping member 250. By providing the avoidance groove 140, it is possible to avoid interference with the instrument 500 passing through the mounting groove 211 located at the target position, thereby improving the adaptability of the guide device 10.

[0088] Furthermore, the avoidance groove 140 is located on a side away from the third support plate 160 , that is, in this embodiment, the target position is located on a side away from the third support plate 160 , thereby reducing interference of other components on the instrument 500 and improving the adaptability of the guide device 10 .

[0089] See also Figure 1 , Figure 4 and Figure 6 In one embodiment, at least one side of the clamping member 250 along the extension direction of the first axis 410 is provided with a size mark 215 corresponding to each mounting hole 230 and exposed to the outside through the corresponding observation hole 120.

[0090] Specifically, the first support plate 110 is located above the second support plate 150, the observation hole 120 is provided on the first support plate 110, and the size mark 215 is located on the side of the turntable 210 facing the first support plate 110. Each size mark 215 is the outer contour size of the device 500 to which the corresponding mounting hole 230 is adapted, so that by viewing each size mark 215 through the observation hole 120, the mounting hole 230 corresponding to the device 500 can be quickly found, and the mounting hole 230 can be adjusted to the target position, thereby improving the efficiency of the guide device 10 in positioning the device 500.

[0091] Furthermore, each size mark 215 is located on the radially inward side of the corresponding mounting groove 211 of the turntable 210 , so that the position of the corresponding mounting hole 230 can be quickly determined according to the size mark 215 .

[0092] In other embodiments, the first support plate 110 may be located below the second support plate 150 , the viewing hole 120 is disposed on the second support plate 150 , and the size mark 215 is located on a side of the turntable 210 facing the second support plate 150 .

[0093] See also Figure 1 and Figure 6 In one embodiment, the observation hole 120 located on the side away from the third support plate 160 is connected to the avoidance groove 140, so as to facilitate processing and reduce the processing technology.

[0094] See also Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 In one embodiment, the positioning component 200 is provided with a limiting groove 241 corresponding to each mounting hole 230, and the limiting component 300 is provided with a limiting end 321, which is used to be plugged into and cooperated with the corresponding limiting groove 241 to limit the rotation of the positioning component 200, so as to position the instrument 500 inserted into the mounting hole 230 at the target position.

[0095] Specifically, the limit grooves 241 are circumferentially arranged on the mating disk 242. By arranging the limit grooves 241 corresponding to each mounting hole 230, when the limit end 321 is plugged into the corresponding limit groove 241, the mounting hole 230 of the required size can be stably positioned at the target position, thereby reducing the repositioning operation of the mounting hole 230 and improving the efficiency of the guide device 10 in positioning the device 500.

[0096] When it is necessary to adjust the mounting hole 230 at the target position, the limit end 321 is located outside the limit groove 241, so that the turntable 210 can be controlled to rotate relative to the bracket 100 around the first axis 410. After the rotation is completed, the limit end 321 extends into the corresponding limit groove 241 and abuts against the corresponding groove wall of the limit groove 241, thereby limiting the rotation of the rotating member 240, so that the device 500 inserted into the mounting hole 230 can be stably maintained at the target position.

[0097] See also Figure 1 , Figure 3 , Figure 7 , Figure 8 and Fig. 9 In one embodiment, the limiting assembly 300 includes an action member 320 and an elastic member 330; a first boss is provided on the side of the action member 320 facing the limiting groove 241, and the first boss is configured as a limiting end 321; one end of the elastic member 330 is connected to the bracket 100, and the other end is connected to the side of the action member 320 away from the first boss, and the elastic member 330 is used to apply a force to the action member 320 toward the limiting groove 241, and is plugged into and matched with the corresponding limiting groove 241.

[0098] Specifically, one end of the elastic member 330 away from the action member 320 is connected to the third support plate 160, and the limiting end 321 cooperates with the limiting groove 241 close to the third support plate 160. Through the setting of the elastic member 330, the action member 320 can be stably engaged with the limiting groove 241, and at the same time, through the contraction of the elastic member 330, the limiting end 321 can be easily moved out of the limiting groove 241, releasing the matching disk 242, thereby releasing the rotating disk 210. Preferably, the elastic member 330 is a spring.

[0099] See also Figure 7 , Figure 8 and Fig. 9 In one embodiment, the limiting assembly 300 further includes a fixing seat 310 , which is connected to the bracket 100 , and a matching hole 311 is provided on the fixing seat 310 , and the action member 320 is passed through the matching hole 311 .

[0100] Specifically, the fixing seat 310 is arranged on the first support plate 110, and the setting of the active member 320 passing through the matching hole 311 can limit the active member 320, so that the abutting end will not deflect under the reaction force of the groove wall of the limiting groove 241, and will always be plugged and matched with the corresponding limiting groove 241, thereby improving the stability of the guide device 10.

[0101] See also Figure 7 , Figure 8 and Fig. 9 In one embodiment, a stopper 322 is protruded from the side of the action member 320 close to the elastic member 330, and a notch 312 is provided on the hole wall of the matching hole 311 close to the elastic member 330, and the notch 312 is used to avoid the stopper 322; the action member 320 is configured to be able to rotate around the axis of the matching hole 311 so that the stopper 322 is located outside the notch 312 and abuts against the fixing seat 310 to limit the limiting end 321 from being inserted into each limiting groove 241.

[0102] Specifically, the matching hole 311 extends in the radial direction of the rotating disk 210. When the rotating disk 210 needs to be restricted from rotating, the action member 320 is moved toward the corresponding limiting groove 241, so that the stopper 322 is accommodated in the notch 312; when the rotating disk 210 needs to be controlled to rotate relative to the bracket 100, the action member 320 is rotated so that the stopper 322 and the notch 312 are staggered in the radial direction of the rotating disk 210, so that under the action of the elastic member 330, the stopper 322 will abut against the side of the fixing seat 310 close to the elastic member 330, and the action member 320 can be restricted from moving toward the corresponding limiting groove 241, so that the limiting end 321 is located outside the limiting groove 241, thereby freeing both hands and improving the adaptability of the wire guide device.

[0103] Furthermore, a second boss is provided on the side of the first boss facing away from the turntable 210, and the size of the second boss on the plane perpendicular to the first axis 410 is larger than that of the first boss. The second boss is configured as a supporting end 323. When the first boss is inserted into the corresponding limiting groove 241, the second boss abuts against the mating disk 242 to limit the rotating member 240 from falling out.

[0104] Furthermore, a third boss 324 is provided on the side of the action member 320 facing the elastic member 330, a fourth boss 161 is provided on the third support plate 160, and both ends of the elastic member 330 are respectively sleeved on the third boss 324 and the fourth boss 161, thereby facilitating the rotation of the action member 320.

[0105] See also Figure 1 , Figure 3 and Fig.10 , Fig.10 A schematic diagram of a guide device provided in one embodiment of the present invention. An embodiment of the present invention also provides a guide device, comprising a posture adjustment device 20 and the above-mentioned guide device 10, wherein the posture adjustment device 20 is connected to the guide device 10, and the posture adjustment device 20 is used to drive the guide device 10 to move so as to adjust the position of the guide device 10.

[0106] Specifically, in this embodiment, the guide device 10 is positioned at the surgical site by the posture adjustment device 20 to complete the guidance of an instrument 500. When the same surgical site needs to be replaced with an instrument 500 with a different cross-sectional size to continue the operation, it is only necessary to place the limit end 321 again. Figure 1 The state shown in the figure can then be adjusted to the position of the mounting hole 230 without repeating the positioning operation.

[0107] In this embodiment, a plurality of mounting holes 230 of different sizes are provided on the positioning assembly 200, and at least a portion of the side wall of each mounting hole 230 can abut against the corresponding instrument 500, so that instruments 500 of different sizes can be stably fixed in the corresponding mounting holes 230, so that the center lines of the instruments 500 of different sizes coincide with the center lines of the corresponding mounting holes 230, and the center lines of each mounting hole 230 are equidistant from the first axis 410 and are parallel to the first axis 410. In the process of the clamping member 250 rotating relative to the bracket 100 around the first axis 410, the center lines of each mounting hole 230 can be rotated to the target position, so that the center line of the instrument 500 passing through the mounting hole 230 can be rotated to the target position to accurately align with the surgical site, and the positioning assembly 200 is limited in rotation by the limit assembly 300, so that the instrument 500 is stably positioned at the target position, which is convenient for surgery. Compared with the prior art, in the present application, when replacing instruments 500 of different sizes, there is no need to replace parts and reposition the guide device 10, which reduces the work of disassembly, installation and positioning adjustment and improves surgical efficiency.

[0108] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0109] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
