[0053] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0054] In this embodiment, the electromagnetic navigation sensor and the intraoperative ultrasound probe can be connected via a specific snap-fit ​​assembly and a protective tube fixture. The snap-fit ​​assembly secures the electromagnetic navigation sensor to the ultrasound transmitter. The protective tube fixture is used for mounting the intraoperative ultrasound probe and the sensor wiring harness of the electromagnetic navigation sensor.

[0055] like Figures 9 to 11As shown, the protective tube fixture mainly includes a protective long tube 1. A handle fixing assembly 3 is provided at the rear end of the protective long tube 1. The intraoperative ultrasound probe can be inserted into the protective long tube 1 through the handle fixing assembly 3. The probe handle 40 of the intraoperative ultrasound probe is fixed inside the handle fixing assembly 3, and the ultrasonic wave emitting part of the intraoperative ultrasound probe can extend out of the front end of the protective long tube 1. The latching assembly includes a probe latch 16, a latching slot 26, and a clamping member 17. The probe latch 16 can be sleeved on the ultrasonic wave emitting part. The probe latch 16 has an emission avoidance groove 160 to avoid the ultrasonic wave emission window 41. The latching slot 26 is installed inside the probe latch 16, and the electromagnetic navigation sensor is installed on the latching slot 26, fitting against the outside of the ultrasonic wave emitting part under the action of the probe latch 16. The clamping member 17 can be sleeved on the rear end of the probe latch 16 to hold the probe latch 16 tightly on the ultrasonic wave emitting part. After use, disassembly is required. The disassembly steps include first detaching the clamping member from the probe latch. This embodiment provides an installation and removal device for installing and removing clamping components.

[0056] like Figure 1a and Figure 2 As shown, the installation and disassembly device includes:

[0057] The propulsion mechanism 18 includes a moving end 180 and a pushing end 181. The moving end 180 is configured to move linearly along an axial direction parallel to the intraoperative ultrasound probe 4.

[0058] The pushing end 181 is disposed on the moving end 180 and is movably connected to the moving end 180 so that the pushing end 181 can reciprocate between a first position and a second position. The first position is the position where the pushing end 181 is separated from the clamping member 17, and the second position is the position where the pushing end 181 is connected to the clamping member 17.

[0059] A locking structure 25 is provided on the mobile end 180. The locking structure 25 is used to lock the pushing end 181 in a first position and to release the pushing end 181.

[0060] Specifically, in this embodiment, during installation, the pushing end 181 can first be moved to the first position to make room for the installation of the intraoperative ultrasound probe 4. The pushing end 181 is locked by the locking structure 25. After the intraoperative ultrasound probe 4 passes through the clamping member 17 and into the probe buckle 16, the moving end 180 moves. After reaching the installation position, the locking structure 25 unlocks and releases the pushing end 181. The pushing end 181 moves to the second position and connects with the clamping member 17. As the moving end 180 moves further forward, the pushing end 181... The push clamping member 17 is engaged with the probe clip 16. During disassembly, the push end 181 is moved to the first position and locked. Then, the intraoperative ultrasound probe 4, which is equipped with the probe clip 16 and the clamping member 17, is moved to the disassembly position. The moving end 180 drives the push end 181 to the disassembly position and then releases the push end 181. The push end 181 moves to the second position and connects with the clamping member 17. As the moving end 180 moves backward, the push end 181 pushes the clamping member 17 to disengage from the probe clip 16.

[0061] In this embodiment, the movement of the pushing end 181 between the first and second positions is not limited. In one embodiment, the pushing end 181 can move horizontally in a linear manner to approach and move away from the intraoperative ultrasound probe 4. In another embodiment, the pushing end 181 can rotate to approach and move away from the intraoperative ultrasound probe 4. Furthermore, this embodiment does not limit the specific structure of the locking structure 25. In one embodiment, the locking structure 25 can be a spring-loaded buckle, a pin, or a locking screw, etc.

[0062] To facilitate the installation of the propulsion mechanism 18, the installation and disassembly device in this embodiment also includes a base 11. A linear drive mechanism 14 is provided on the base 11. The linear drive mechanism 14 is connected to the moving end 180 for driving the moving end 180 to move linearly.

[0063] In this embodiment, the linear drive mechanism 14 can be a lead screw drive mechanism, a cylinder, a hydraulic cylinder, etc., and no limitation is made here. When the linear drive mechanism 14 is set as a lead screw drive mechanism, the lead screw slider of the lead screw drive mechanism is fixedly connected to the moving end 180. The lead screw 141 of the lead screw drive mechanism rotates to drive the slider to move linearly, thereby driving the moving end 180 to move linearly. The pushing end 181 serves as the structure for pushing the clamping member 17. In this embodiment, the pushing end 181 includes a clamping member that can move linearly along the radial direction of the intraoperative ultrasound probe 4. During installation, the clamping member is controlled to move toward the intraoperative ultrasound probe 4. The clamping member is used to clamp onto the clamping member 17 or abut against the end face of the clamping member 17, thereby pushing the clamping member 17 to move under the action of the moving end 180, so as to fit and fix it on the probe buckle 16.

[0064] In one embodiment of the linear drive mechanism 14, such as Figures 1a to 3As shown, the linear drive mechanism 14 includes a lead screw transmission mechanism and a guide shaft 24, both of which are mounted on the base 11.

[0065] The movable end 180 is fixedly connected to the lead screw slider of the lead screw transmission mechanism, and the movable end 180 is slidably sleeved on the guide shaft 24.

[0066] In this embodiment, the guide shaft 24 is mounted on the base 11, and both ends of the guide shaft 24 can be fixed inside the guide seat, which is fixed on the base 11. The axis of the guide shaft 24 is parallel to the axis of the intraoperative ultrasound probe 4. The guide shaft 24 can guide the linear movement of the moving end 180, and at the same time enable the lead screw 141 of the lead screw transmission mechanism to drive the lead screw slider to move linearly.

[0067] In one embodiment of the lead screw drive mechanism, such as Figure 3 As shown, the lead screw transmission mechanism includes a lead screw 141, a lead screw slider, a lead screw mounting base, and a rocker wheel 140. The lead screw 141 is hinged to the lead screw mounting base, and the lead screw slider is threadedly connected to the lead screw 141.

[0068] Specifically, in this embodiment, the lead screw 141 is arranged parallel to the intraoperative ultrasound probe 4. The lead screw mounting base is fixed on the base 11 and connected to both ends of the lead screw 141 by bearings, allowing the lead screw 141 to rotate on a fixed axis on the lead screw mounting base. To facilitate driving the lead screw 141 to rotate, in this embodiment, the front end of the lead screw 141 extends out of the base 11 and is connected to the rocker wheel 140. During installation, the rocker wheel 140 can be operated to rotate, driving the lead screw 141 to rotate, thereby driving the lead screw slider and the moving end 180 to move linearly.

[0069] like Figure 2 As shown, in order to facilitate the movement of the clamping member 17, the moving end 180 in this embodiment is set into two sets and symmetrically distributed on both sides of the base 11. The guide shaft 24 is set into two sets and slidably connected to the moving end 180 on both sides respectively. The screw transmission mechanism is located between the two moving ends 180, and the two sets of moving ends 180 are fixedly connected to the screw slider.

[0070] Specifically, in this embodiment, the lead screw 141 is positioned between the two sets of moving ends 180, and the lead screw slider is threadedly connected to the lead screw 141. Both sides of the lead screw slider are fixedly connected to the two sets of moving ends 180 via connecting plates. Each of the two sets of moving ends 180 is provided with a set of pushing ends 181. During installation, the two sets of pushing ends 181 are located on both sides of the intraoperative ultrasound probe 4, allowing the two sets of pushing ends 181 to move synchronously towards the intraoperative ultrasound probe 4, thereby connecting with both sides of the clamping member 17. In this embodiment, by setting two sets of moving ends 180 and two sets of pushing ends 181, the clamping member 17 is subjected to balanced forces during installation, preventing misalignment and blockage.

[0071] like Figures 2 to 5 As shown, in one embodiment of the mobile end 180, the mobile end 180 includes a mobile base 1800, the push end 181 also includes a third spring 1811, the clamping member includes a push rod 1810 and a clamping ring 1812, the push rod 1810 is slidably disposed in the mobile base 1800 and can be driven to move linearly in the mobile base, and the third spring 1811 is sleeved on the push rod 1810;

[0072] The front end of the push rod 1810 extends into a movable end 180 and is fixedly connected to the clamping ring 1812. After the clamping ring 1812 clamps, it abuts against the rear end face of the clamping member 17. The rear end of the push rod 1810 extends into a movable seat 1800.

[0073] Specifically, during installation and disassembly, the rear end of the push rod 1810 can be pulled outward to move the clamping ring 1812 located at the front end of the push rod 1810 backward, making room for the installation of the intraoperative ultrasound probe 4. During this process, the push rod 1810 will compress the third spring 1811. Then, the intraoperative ultrasound probe 4 is installed into the probe clip 16, at which point the clamping member 17 is also sleeved on the intraoperative ultrasound probe 4. Then, the push rod 1810 is released, and the clamping ring 1812 at the front end of the push rod 1810 moves towards the intraoperative ultrasound probe 4 under the action of the third spring 1811. During installation, the clamping ring 1812 moves to the rear end of the clamping member 17, which controls the movement of the moving seat 1800. During the movement, the clamping ring 1812 pushes the rear end face of the clamping member 17, causing the clamping member 17 to move forward linearly on the intraoperative ultrasound probe 4 until it is sleeved on the probe clip 16.

[0074] The same principle applies to disassembly, except that the clamping ring 1812 is in a different position when closed. When disassembly, after the clamping ring 1812 is closed, it is located at the front end of the clamping member 17, and the rear end face of the clamping ring 1812 is in contact with the front end face of the clamping member 17. The clamping member 17 is removed by moving the clamping ring 1812 backward.

[0075] like Figure 5 As shown, in order to keep the clamping ring 1812 in the open state before installation and disassembly, a locking structure 25 is provided in the movable seat 1800 in this embodiment. The locking structure 25 is used to lock the push rod 1810 in the first position, which is the open position of the clamping ring 1812.

[0076] Furthermore, in this embodiment, it is desirable that the clamping ring 1812 automatically closes and clamps the front end of the locking member 17 when the operating movable end 180 is moved to the installation or disassembly position. Therefore,

[0077] like Figure 1a and Figure 5As shown, a first linkage structure 15 is provided on the base 11. The first linkage structure 15 is located in the moving direction of the movable seat 1800. The first linkage structure 15 is configured to be linked with the locking structure 25. When the movable seat 1800 moves to the installation position or the disassembly position, the first linkage structure 15 triggers the locking structure 25 to release the clamping ring 1812. In this embodiment, the installation position is the position where the front end face of the clamping ring 1812 is close to the rear end face of the clamping member 17, and the disassembly position is the position where the rear end face of the clamping ring 1812 is close to the front end face of the clamping member 17.

[0078] Specifically, before use, the movable seat 1800 is in its initial position. At this time, the push rod 1810 can be manually pulled outward. When the push rod 1810 is pulled to the first position, the locking structure 25 is triggered, locking the push rod 1810 in the first position. In this embodiment, the first position of the push rod 1810 corresponds to the open position of the clamping ring 1812, that is, when the clamping ring 1812 is in this position, the intraoperative probe can be installed. After the push rod 1810 is locked in the first position, the intraoperative ultrasound can be installed into the probe clip 16, and then the movable seat 1800 can be controlled to move forward.

[0079] When the movable seat 1800 moves forward to the installation position, the first linkage structure 15 on the base 11 triggers the locking structure 25 inside the movable seat 1800. At this time, the locking structure 25 releases the push rod 1810, and the push rod 1810 will move inward under the action of the third spring 1811, causing the clamping ring 1812 to move toward the intraoperative ultrasound probe 4. Since the clamping ring 1812 needs to abut against the rear end face of the clamping member 17 to push the clamping member 17 to move, the second position in this embodiment refers to the position of the movable seat 1800 when the projection of the clamping ring 1812 on the intraoperative ultrasound probe 4 is close to the rear end face of the clamping member 17.

[0080] The same principle applies to disassembly, except that the trigger position of the locking mechanism differs from that during installation. During disassembly, the trigger position is further forward than during installation.

[0081] In this embodiment, the locking structure 25 and the first linkage structure 15 can be configured in various forms, and can be triggered by a mechanical structure. Specifically, for example... Figure 5 As shown, a slot 1813 can be provided on the push rod 1810. The locking structure 25 includes a locking rod 252 and a fourth spring 251 provided in the movable seat 1800. The locking rod 252 is hinged in the base 11. The fourth spring 251 is connected to the locking rod 252. The first end of the locking rod 252 is engaged with the slot 1813.

[0082] The second end of the lever 252 extends out of the lower end of the movable seat 1800 and corresponds to the first linkage structure 15. When the movable seat 1800 moves to the second position, the first linkage structure 15 pushes the second end of the lever 252 to rotate the lever 252 so that the first end of the lever 252 disengages from the slot 1813.

[0083] When the movable seat 1800 is in the initial position, the push rod 1810 can be pulled outward. When the push rod 1810 is pulled to the first position, the slot 1813 corresponds to the first end of the locking rod 252. Under the action of the fourth spring 251, the first end of the locking rod 252 is locked into the slot 1813 to lock the push rod 1810. At this time, the second end of the locking rod 252 extends out of the lower end of the movable seat 1800.

[0084] As the movable seat 1800 moves to the set position, the second end of the locking lever 252 gradually approaches the first linkage structure 15. Once the second end of the locking lever 252 contacts the first linkage structure 15, as the movable seat 1800 moves further, the locking lever 252 will rotate around the hinge point, causing the first end of the locking lever 252 to gradually disengage from the slot 1813. When the movable seat 1800 reaches the set position, the first end of the locking lever 252 completely disengages from the slot 1813. At this time, the push rod 1810, under the action of the third spring 1811, pushes the clamping ring 1812 forward to the second position, aligning it with the rear end face of the locking member 17.

[0085] like Figure 5 As shown, in one embodiment, the latch 252 may include two vertical parts and one horizontal part, with the two vertical parts fixed to both ends of the horizontal part. The middle part of the horizontal part is hinged to the movable seat 1800 via a pivot. The vertical part located at the front end of the horizontal part is used to engage with the latch 1813. The vertical part located at the rear end of the horizontal part can extend out of the lower end of the movable seat 1800 and engage with the first linkage structure 15. The lower end of the fourth spring 251 is connected to the horizontal part.

[0086] In order to enable the first end of the locking rod 252 to automatically engage with the slot 1813 when the push rod 1810 is pulled to the first position, in this embodiment, an inclined surface can be provided on the first end of the locking rod 252 and the push rod 1810 at the rear end of the slot 1813, and the automatic engagement can be achieved by the cooperation of the two inclined surfaces.

[0087] Based on the above implementation methods, such as Figure 1a As shown, the first linkage structure 15 includes a linkage block fixed on the base 11. The linkage block is provided with a linkage inclined surface 150 and a linkage plane 151. The linkage inclined surface 150 and the linkage plane 151 are arranged sequentially along the moving direction of the movable seat 1800 toward the disassembly seat.

[0088] Specifically, in this embodiment, the linkage blocks are arranged on both sides of the base 11 and correspond to the movable seat 1800. The upper surface of the linkage block includes a linkage inclined surface 150 and a linkage plane 151. When the push rod 1810 is locked by the locking rod 252, as the movable seat 1800 moves forward, the second end of the locking rod 252 gradually approaches the linkage inclined surface 150. When the second end of the locking rod 252 contacts the linkage inclined surface 150, as the movable seat 1800 moves further, the locking rod 252 will rotate around the hinge point, causing the first end of the locking rod 252 to gradually disengage from the slot 1813 on the push rod 1810. When the second end of the locking rod 252 moves to the linkage plane 151, the first end of the locking rod 252 completely disengages from the slot 1813 to release the clamping ring 1812, which will be attached to the intraoperative ultrasound probe 4 and located at the rear end of the clamping member 17. As the movable seat 1800 moves further, the second end of the lever 252 will move on the linkage plane 151. During this process, the clamping ring 1812 pushes the clamping member 17 toward the probe buckle 16 and engages with the probe buckle 16.

[0089] To reduce the friction between the second end of the locking lever 252 and the linkage block, a second rolling element 253 is provided at the second end of the locking lever 252 in this embodiment. The second rolling element 253 is used to cooperate with the linkage inclined surface 150 and the linkage plane 151. The second rolling element 253 can be a ball bearing or a bearing, etc., and this embodiment does not limit it.

[0090] It is understood that, in this invention, the locking structure 25 and the first linkage structure 15 can be linked electrically in addition to mechanically. Specifically, the locking structure 25 can electrically lock and release the push rod 1810, for example, the locking structure 25 can be an electromagnetic lock. During the movement of the movable seat 1800, the position of the movable seat 1800 can be detected by a corresponding displacement sensor. When the movable seat 1800 moves to the second position, a corresponding electrical signal is triggered, and the locking structure 25 is controlled to release the push rod 1810.

[0091] To better promote the clamping component 17, such as Figure 5 As shown, in this embodiment, the clamping ring 1812 is set as a semi-circle, and the upper and lower ends of the clamping ring 1812 on both sides are provided with a first plug-in part and a second plug-in part for plug-in cooperation.

[0092] Because the trigger position of the locking structure 25 differs during installation and disassembly, the position of the linkage block needs to be adjusted to match the installation and disassembly processes for the same locking structure 25. In this embodiment, a first installation position (e.g., ...) is provided on the base 11. Figure 8 (as shown) and second installation location (such as) Figure 1aAs shown), the first and second installation positions are arranged sequentially along the forward direction of the movable seat 1800, and the linkage block can be selectively installed in the first or second installation position.

[0093] The first installation position is used for the linkage block and the locking rod 252 to be linked during the installation of the clamping component 17, and the second installation position is used for the linkage block and the locking rod 252 to be linked during the disassembly of the clamping component 17.

[0094] Since the clamping member 17 needs to be pushed backward during disassembly, the probe clip 16 needs to be fixed during disassembly to prevent it from moving. In this embodiment, the probe clip 16 is fixed by the positioning mechanism 19. Based on the above linkage method, this embodiment makes the positioning mechanism 19 linked with the movement of the moving seat 1800. It is expected that when the moving seat 1800 moves to the disassembly position, the positioning mechanism 19 can move to the position where the probe clip 16 is fixed.

[0095] Therefore, as Figure 3 As shown, in this embodiment, a second linkage structure 20 is also provided on the base 11. The second linkage structure 20 is configured to be able to link with the positioning mechanism 19 and the propulsion mechanism 18.

[0096] When the movable seat 1800 moves to the first disassembly position, the second linkage structure 20 triggers the positioning mechanism to perform the action of fixing the probe latch 16; when the movable seat 1800 moves to the second disassembly position, the second linkage structure 20 triggers the positioning mechanism to perform the action of releasing the probe latch 16.

[0097] Specifically, in this embodiment, when the movable seat 1800 is in the initial position, the positioning mechanism 19 is also in the initial position, and the positioning mechanism 19 will not interfere with the insertion of the probe clip 16 into the disassembly slot 130. When the movable seat 1800 moves to the first disassembly position (i.e., after the clamping ring 1812 is located at the front end of the clamping member 17), the positioning mechanism 19 moves to a position that can fix the probe clip 16 under the action of the second linkage structure 20. When the movable seat 1800 moves backward to complete the disassembly of the clamping member 17, that is, after the movable seat 1800 moves to the second disassembly position, the positioning mechanism 19 resets under the action of the second linkage structure 20 and releases the probe clip 16.

[0098] After setting the second linkage structure 20 and locking the clamping ring 1812 to the open position, simply control the moving seat 1800 to move forward to automatically complete the closing of the clamping ring 1812 and the fixing of the probe buckle 16 by the positioning mechanism 19. Then, operate the moving seat 1800 to move backward to complete the disassembly of the clamping part 17 and the release of the probe buckle 16.

[0099] In one embodiment of the positioning mechanism 19, such as Figure 4As shown, the positioning mechanism 19 includes a positioning block 190 and a third elastic part 191. The positioning block 190 includes a blocking part, which is located behind the disassembly groove 130.

[0100] The positioning block 190 is connected to the third elastic part 191, and the positioning block 190 is disposed on the base 11 and can move linearly along the radial direction of the intraoperative ultrasound probe 4, so that the blocking part can move under the action of the third elastic part 191 to fit against the rear end face of the probe buckle 16.

[0101] The movable seat 1800 is linked to the positioning block 190 through the second linkage structure 20.

[0102] Specifically, in this embodiment, the third elastic part 191 can use its elastic force to push the positioning block 190 to move linearly along the radial direction of the intraoperative ultrasound probe 4, so that during disassembly, the blocking part on the positioning block 190 can abut against the rear end face of the probe clip 16, thereby overcoming the tension on the probe clip 16 during disassembly. In this embodiment, the positioning block 190 can be set at the rear end of the disassembly seat 13 and located below the disassembly groove 130. The blocking part can be a baffle plate set at the upper end of the positioning block 190. The third elastic part 191 can be a spring, and a corresponding spring mounting post can be set at the front end of the disassembly seat 13. The spring is sleeved on the spring mounting post and connected to the positioning block 190. The moving seat 1800 is connected to the positioning block 190 through the second linkage structure 20, so that the positioning block 190 can be linked with the moving seat 1800.

[0103] In one embodiment of the second linkage structure 20, the second linkage structure 20 may be a traction rope and a winding wheel. The winding wheel may be arranged on the movable seat 1800 and may be connected by a torsion spring. The two ends of the traction rope are respectively connected to the winding wheel and the positioning block 190, and the movement of the positioning block 190 is controlled by the movement of the movable seat 1800.

[0104] like Figure 4 As shown, in another embodiment of the second linkage structure 20, the second linkage structure 20 includes a slide rail 205 and a support leg 204; the slide rail 205 is fixed on the movable seat 1800 and can move linearly on the base 11 with the movable seat 1800; the lower end surface of the slide rail 205 is provided with a track surface, the track surface includes a first surface 201, a second surface 202 and a third surface 203 distributed sequentially in the direction toward the disassembly seat 13; the first surface 201 is higher than the third surface 203; the second surface 202 is set as an inclined surface connecting the first surface 201 and the second surface 202.

[0105] The support leg 204 is fixed on the positioning block 190. When the movable seat 1800 moves to the first disassembly position, the support leg 204 abuts against the first surface 201, and the blocking part moves to fit against the rear end surface of the probe buckle 16 under the action of the third elastic part 191. When the movable seat 1800 moves to the first position, the support leg 204 abuts against the third surface 203.

[0106] Specifically, in this embodiment, when the movable seat 1800 is in the first disassembly position, the support leg 204 abuts against the lower third surface 203. At this time, the positioning block 190 is in its initial position and compresses the third elastic part 191. As the movable seat 1800 moves forward from the first disassembly position to the second disassembly position, the second surface 202 on the track gradually contacts the support leg 204. Since the second surface 202 is an inclined surface and connects to the higher first surface 201, the support leg 204 gradually rises under the action of the third elastic part 191 during the contact with the second surface 202, causing the positioning block 190 to gradually rise as well. When the movable seat 1800 moves to the second position, the support leg 204 contacts the first surface 201 and slides a certain distance on the first surface 201. This distance is consistent with the amount of movement required to disassemble the clamping member 17. At this time, the support leg 204 and the positioning block 190 are at their highest positions under the action of the third elastic part 191, and the blocking part on the positioning block 190 rises to fit against the rear end face of the probe buckle 16.

[0107] During disassembly, the movable seat 1800 moves from the first disassembly position to the second disassembly position, and the support leg 204 gradually moves from the first surface 201 through the second surface 202 to the third surface 203. During this process, the positioning block 190 gradually moves to the initial position.

[0108] To reduce the friction between the support leg 204 and the track surface, in this embodiment, a third rolling element 205 is provided on the support leg 204. The third rolling element 205 abuts against the track surface. The third rolling element 205 can be a bearing or a ball bearing.

[0109] Regarding the disassembly of the ultrasound probe during surgery, such as Figures 1a to 7 As shown, this embodiment provides a disassembly tool for the intraoperative ultrasound probe 4, comprising:

[0110] Base 11;

[0111] The disassembly seat 13 is provided on the base 11. The disassembly seat 13 is provided with a disassembly groove 130 for accommodating the probe clip 16.

[0112] The advancing mechanism 18 includes a moving end 180 and a pushing end 181. The moving end 180 is configured to move linearly in a direction parallel to the axis of the intraoperative ultrasound probe 4, and the pushing end 181 is configured to push the clamping member 17 to move in a direction away from the disassembly seat 13, so that the clamping member 17 is disengaged from the probe latch 16.

[0113] Positioning mechanism 19 is provided on base 11. Positioning mechanism 19 is used to fix probe buckle 16 in disassembly groove 130.

[0114] In this embodiment, the disassembly fixture mainly includes a base 11, a disassembly seat 13, a pushing mechanism 18, and a positioning mechanism 19. The base 11 serves as the basic installation structure and can be a long, plate-like structure, or other structural forms; this embodiment does not impose any limitations. The disassembly seat 13, serving as a structure to accommodate the probe clip 16, can be installed at the first end of the base 11. The disassembly seat 13 is provided with a horizontally extending disassembly groove 130. The upper and rear ends of the disassembly groove 130 are open structures, allowing the intraoperative ultrasound probe 4, equipped with the probe clip 16, to be inserted into the disassembly groove 130 through the rear opening. The upper opening of the disassembly groove 130 facilitates sterilization of the entire disassembly fixture after disassembly.

[0115] Since the intraoperative ultrasound probe 4 is a long strip structure, in order to facilitate the support of the intraoperative ultrasound probe 4 during disassembly, in this embodiment, several support seats 12 can be provided on the base 11. The support seats 12 have support grooves 120, which can accommodate the intraoperative ultrasound probe 4 or the protective tube sleeved on the intraoperative ultrasound probe 4.

[0116] To disassemble the clamping member 17 that is sleeved on the probe clip 16, it is necessary to push the clamping member 17 outward along the axial direction of the intraoperative ultrasound probe 4 to disengage it from the probe clip 16. For this purpose, the disassembly fixture in this embodiment also includes a pushing mechanism 18. The pushing mechanism 18 mainly includes a moving end 180 and a pushing end. The moving end 180 is mainly used to drive the pushing end 181 to move, while the pushing end 181 is mainly used to maintain connection with the clamping member 17, thereby pushing the clamping member 17 under the action of the moving end 180.

[0117] Before disassembly, the pushing end 181 needs to be adjusted to at least open to allow space for the installation of the intraoperative ultrasound probe 4. After the intraoperative ultrasound probe 4 is installed into the disassembly fixture, the pushing end 181 is adjusted again to close and connect with the clamping member 17. Specifically, the pushing end 181 can be clamped and fixed to the clamping member 17 or abut against the front end face of the clamping member 17. The moving end 180 is used to adjust the position of the pushing end 181 so that it can connect with the clamping member 17.

[0118] After the pushing end 181 completes the connection with the clamping member 17, or during the connection process, the positioning mechanism 19 is activated, fixing the probe clip 16 within the disassembly groove 130. This prevents the probe clip 16 from moving during the pushing of the clamping member 17, thus preventing it from becoming unremovable. Since the positioning mechanism 19 only needs to fix the probe clip 16 within the disassembly groove 130, various structural forms can be adopted. In one embodiment, the positioning mechanism 19 can be controlled to move to abut against the rear end face of the probe clip 16, thereby overcoming the backward pulling force on the probe clip 16 during disassembly. In another embodiment, a locking structure can be used to press the probe clip 16 against the disassembly groove 130. In this embodiment, the specific structure of the positioning mechanism 19 is not limited.

[0119] In one embodiment of the electromagnetic navigation sensor installation, the electromagnetic navigation sensor is mounted to the probe clip 16 via a slot 1813. Therefore, when disassembling the electromagnetic navigation sensor, the slot 1813 needs to be removed from the probe clip 16. The slot 1813 is generally snapped into the inner bottom surface of the probe clip 16. Therefore, in this embodiment, to remove the slot 1813, a push rod 22 is hinged inside the disassembly base 13. A pressure rod 21 and a top block 23 are provided on the disassembly base 13. The pressure rod 21 and the top block 23 correspond to the two ends of the push rod 22 and can move vertically on the disassembly base 13. The upper end of the pressure rod 21 extends out of the upper end of the disassembly base 13, and the upper end of the top block 23 can extend out of the bottom surface of the disassembly groove 130 and insert into the disassembly hole of the probe clip 16 under the pushing action of the pressure rod 21.

[0120] During disassembly, the pressure rod 21 can be pressed down, which in turn presses down on the front end of the top rod 22. The top rod 22 rotates, causing the rear end to push the top block 23 upward and insert it into the disassembly hole at the lower end of the probe clip 16, and push the clip slot 1813 upward, so that the clip slot 1813 is disengaged from the probe clip 16.

[0121] Additionally, it should be noted that during the installation and disassembly of the clamping component, the clamping ring abuts against the end face of the clamping component to push the clamping component to move, thereby completing the installation and disassembly. Because the clamping component 17 is relatively thin, during disassembly, if the clamping ring 1812 abuts against the front face of the clamping component 17 to push the clamping component 17, the clamping ring 1812 and the clamping component 17 are prone to slippage, leading to disassembly failure. Therefore, in this embodiment, positioning protrusions 18120 are provided on both ends of the clamping ring 1812 close to the clamping component 17. At least two positioning protrusions 1820 are provided on each end and are located on both sides of the clamping ring 1812. The positioning protrusions 18120 are used to engage and fit against the inner side of the clamping component 17 before pushing it, thereby positioning the radial position of the clamping component 17.

[0122] Specifically, in this embodiment, such asFigure 1b As shown, for disassembly, before disassembly, the positioning protrusion 18120 at the rear end of the clamping ring is located in front of the clamping member 17, and the clamping member 17 and the probe latch 16 are in a clamping state. To allow the positioning protrusion 18120 to engage with the inner side of the clamping member 17, a clearance groove 160 needs to be provided on the portion of the probe latch 16 that engages with the clamping member 17. In one embodiment, the clamping portion of the probe latch 16 includes several clamping plates, with adjacent clamping plates spaced apart to form the clearance groove 160. During installation, the clamping member 17 clamps onto the clamping plates, thereby clamping the clamping plates onto the intraoperative ultrasound probe. In another embodiment, the clearance groove 160 can be directly formed at the rear end of the probe latch 16, allowing the positioning protrusion 18120 to engage with the inner side of the clamping member 17 through the clearance groove 160.

[0123] During disassembly, the clamping ring 1812 moves toward the clamping member 17, and the positioning protrusion 18120 is engaged with the inner side of the clamping member 17 through the relief groove 160, making it less likely for the clamping ring 1812 to slip off from the clamping member 17 during further movement. For installation, since the inner diameter of the clamping member 17 is larger than the outer diameter of the intraoperative ultrasound probe 4 during installation, the upper end of the clamping member 17 fits against the upper surface of the intraoperative ultrasound probe 4 after the intraoperative ultrasound probe 4 passes through it. This results in an eccentric relationship between the clamping member 17 and the intraoperative ultrasound probe 4, while the intraoperative ultrasound probe 4 and the probe latch 16 are concentric. Therefore, during the movement of the clamping member 17, the connection between the clamping member 17 and the probe latch 16 is easily obstructed.

[0124] like Figure 1c As shown, after the positioning protrusion 18120 is set at the front end of the clamping ring 1812, the positioning protrusion 18120 is located behind the clamping member 17 before installation. When the front end of the intraoperative ultrasound probe 4 passes through the clamping member 17 and is inserted into the probe clip 16, the upper end of the clamping member 17 is in contact with the upper surface of the intraoperative ultrasound probe 4 due to its own weight, and the two are in an eccentric state. At this time, the moving end 130 drives the clamping ring 1310 to move towards the clamping member 17, so that the positioning protrusion 13100 is engaged in the clamping member 17. Under the action of the positioning protrusions 13100 on both sides, the clamping member 17 moves upward and is positioned to a position concentric with the intraoperative ultrasound probe 4. Pushing the clamping member 17 forward at this point ensures a precise connection between the clamping member 17 and the probe latch 16. Furthermore, since the positioning protrusion 13100 engages with the inside of the clamping member 17, the clamping ring 1310 and the clamping member 17 are less likely to slip during the movement of the clamping member 17, thus improving the stability of the connection process.

[0125] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
