[0054] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0055] In the embodiment, the electromagnetic navigation sensor and the ultrasonic probe can be connected through a specific buckle assembly and a protection tube tool. The buckle assembly is used to fix the electromagnetic navigation sensor on the ultrasonic wave emitting part. The protection tube tool is used for the ultrasonic probe installation and the sensor wire harness installation of the electromagnetic navigation sensor.
[0056] As shown in Figures 8 to 10 , the protection tube tool mainly includes a protection long tube 1. A handle fixing assembly 3 is arranged at the rear end of the protection long tube 1. The ultrasonic probe can be installed into the protection long tube 1 from the handle fixing assembly 3. The ultrasonic wave emitting part of the ultrasonic probe can extend out of the front end of the protection long tube 1. The buckle assembly includes a probe buckle 16, a clamping groove piece 26 and a clamping piece 17. The probe buckle 16 can be sleeved on the ultrasonic wave emitting part. The probe buckle 16 has an emitting avoiding groove 160 for avoiding the ultrasonic wave emitting window 41. The clamping groove piece 26 is installed on the inner side of the probe buckle 16. The electromagnetic navigation sensor is installed on the clamping groove piece 26 and is attached to the outer side of the ultrasonic wave emitting part under the action of the probe buckle 16. The clamping piece 17 can be sleeved on the rear end of the probe buckle 16 to tightly hold the probe buckle 16 on the ultrasonic wave emitting part. After use, the clamping piece needs to be detached from the probe buckle.
[0057] As shown in Figures 1a to 7 , the embodiment provides a dismounting tool for the ultrasonic probe 4, which includes:
[0058] a base 11;
[0059] a dismounting seat 13 arranged on the base 11. The dismounting seat 13 is provided with a dismounting groove 130 for accommodating the probe buckle 16;
[0060] a pushing mechanism 18 including a moving end 180 and a pushing end 181. The moving end 180 is arranged to be linearly movable in a direction parallel to the axial direction of the ultrasonic probe 4. The pushing end 181 is arranged to be connected with the clamping piece 17 and to be movable in a direction away from the dismounting seat 13 under the action of the moving end 180, so as to make the clamping piece 17 detached from the probe buckle 16;
[0061] a positioning mechanism 19 arranged on the base 11. The positioning mechanism 19 is used to fix the probe buckle 16 in the dismounting groove 130.
[0062] In the embodiment, the dismounting tool mainly comprises a base 11, a dismounting seat 13, a pushing mechanism 18 and a positioning mechanism 19. The base 11 is a basic mounting structure, which can be provided in a strip-shaped plate structure, and can also be provided in other structures, which is not limited in the embodiment. The dismounting seat 13, which is used for accommodating the probe buckle 16, is mounted at a first end of the base 11. The dismounting seat 13 is provided with a dismounting groove 130 extending in the horizontal direction, and the upper end and the rear end of the dismounting groove 130 are both open structures. The ultrasonic probe 4 assembled with the probe buckle 16 can be inserted into the dismounting groove 130 from the open structure at the rear end, and the open structure at the upper end of the dismounting groove 130 facilitates disinfection of the entire dismounting tool after dismounting.
[0063] Since the ultrasonic probe 4 is a strip-shaped structure, in order to support the ultrasonic probe 4 during dismounting, a plurality of support seats 12 can be provided on the base 11 in the embodiment, and a support groove 120 is formed in each support seat 12, which can accommodate the ultrasonic probe 4 or the protection long tube 1 to support the ultrasonic probe 4.
[0064] For dismounting the clamping piece 17 sleeved on the probe buckle 16, the clamping piece 17 needs to be pushed outward along the axial direction of the ultrasonic probe 4 to be separated from the probe buckle 16. Therefore, the dismounting tool in the embodiment further comprises a pushing mechanism 18, which mainly comprises a moving end 180 and a pushing end. The moving end 180 is mainly used to drive the pushing end 181 to move, and the pushing end 181 is mainly used to be connected with the clamping piece 17, so as to push the clamping piece 17 under the action of the moving end 180.
[0065] The pushing end 181 needs to be adjusted before dismounting, and at least needs to be opened to leave the mounting space of the ultrasonic probe 4. After the ultrasonic probe 4 is mounted to the dismounting tool, the pushing end 181 is adjusted again to be closed and connected with the clamping piece 17. Specifically, the pushing end 181 can be clamped and fixedly connected with the clamping piece 17 or abut against the front end face of the clamping piece 17. The moving end 180 is used to adjust the position of the pushing end 181, so that the pushing end 181 is in a position capable of being connected with the clamping piece 17.
[0066] After the pushing end 181 completes the connection with the clamping member 17, or during the connection process, the positioning mechanism 19 is activated, and the probe buckle 16 is fixed in the disassembly groove 130 by the positioning mechanism 19, so as to avoid the probe buckle 16 from moving and becoming unable to be disassembled during the process of pushing the clamping member 17. Since the positioning mechanism 19 only needs to realize the function of fixing the probe buckle 16 in the disassembly groove 130, a variety of structural forms can be adopted. In one embodiment, the positioning mechanism 19 can be moved in a controlled manner to abut against the rear end face of the probe buckle 16, thereby overcoming the backward pulling force applied to the probe buckle 16 during the disassembly process. In another embodiment, the probe buckle 16 can be pressed tightly in the disassembly groove 130 by a locking structure. In this embodiment, there is no limitation on the specific structure of the positioning mechanism 19.
[0067] After the probe buckle 16 is fixed and the clamping member 17 is connected, the movable end 180 can be operated again to move linearly away from the disassembly seat 13. The movable end 180 will drive the pushing end 181 to move, thereby pushing the clamping member 17 backward and disengaging the probe buckle 16. Then, the handle fixing assembly 3 of the protective tube fixture is opened, and the ultrasonic probe 4 can be withdrawn backward, completing the disassembly of the ultrasonic probe 4.
[0068] In one embodiment, the movable end 180 can be arranged on the base 11 and driven by a corresponding driving mechanism to move linearly. Of course, the movable end 180 may not be arranged on the base 11, and can be assembled and used as an independent component during installation. The pushing end 181 is connected to the movable end 180. In one embodiment, the pushing end 181 can move linearly along the radial direction of the ultrasonic probe 4. During installation, the pushing end 181 can move linearly close to the ultrasonic probe 4 and be located at the front end of the clamping member 17. At this time, the rear end face of the pushing end 181 is close to or fits with the front end face of the clamping member 17, so that the pushing end 181 can push the clamping member 17 to move linearly backward under the action of the movable end 180. In another embodiment, the pushing end 181 can be clamped on the clamping member 17 and push the clamping member 17 to move by friction. In this embodiment, there is no limitation on the specific structure of the pushing end 181, and those skilled in the art can design it according to actual needs.
[0069] Since the movement of the mobile terminal 180 needs to be controlled during the installation process, in order to facilitate the linear movement of the mobile terminal 180, as shown in FIG. Figures 1a to 3 As shown, a linear drive mechanism 14 is provided on the base 11 in this embodiment. The linear drive mechanism 14 is transmission-connected to the moving end 180 for driving the moving end 180 to move linearly.
[0070] In this embodiment, the linear drive mechanism 14 can be a screw transmission mechanism, a cylinder, a hydraulic cylinder, etc., and there is no limitation on them in this embodiment. When the linear drive mechanism 14 is set as a screw transmission mechanism, the screw slider of the screw transmission mechanism is fixedly connected to the movable end 180, and the screw 141 of the screw transmission mechanism rotates to drive the screw slider to move linearly, thereby driving the movable end 180 to move linearly. The pushing end 181 serves as a 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 ultrasonic probe 4. During installation, the clamping member is controlled to move toward the ultrasonic probe 4, and the clamping member is clamped on the clamping member 17 or pressed against the end face of the clamping member 17, so that the clamping member 17 is pushed to move under the action of the movable end 180 to be fixed on the probe buckle 16.
[0071] In one embodiment of the linear drive mechanism 14, as Figure 1a and Figure 3 As shown, the linear drive mechanism 14 includes a screw transmission mechanism and a guide shaft 24, and the screw transmission mechanism and the guide shaft 24 are both provided on the base 11;
[0072] 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 .
[0073] In this embodiment, the guide shaft 24 is mounted on the base 11. Both ends of the guide shaft 24 can be fixed in the guide seat, which is fixed to the base 11. The axis of the guide shaft 24 is parallel to the axis of the ultrasonic probe 4. The guide shaft 24 can guide the linear movement of the movable end 180 and enable the screw 141 of the screw transmission mechanism to drive the screw slider to move linearly.
[0074] In one embodiment of the screw transmission mechanism, as shown in the figure, the screw transmission mechanism includes a screw 141, a screw slider, a screw mounting seat and a rocker 140, the screw 141 is hinged on the screw mounting seat, and the screw slider is threadedly connected to the screw 141.
[0075] Specifically, in this embodiment, the lead screw 141 is arranged parallel to the ultrasound probe 4. The lead screw mounting base is fixed to the base 11 and connected to both ends of the lead screw 141 via bearings, allowing the lead screw 141 to rotate around a fixed axis on the lead screw mounting base. To facilitate the rotation of the lead screw 141, the front end of the lead screw 141 in this embodiment extends beyond the base 11 and is connected to the rocker 140. During installation, the rocker 140 can be rotated to rotate the lead screw 141, thereby driving the linear movement of the lead screw slider and the movable end 180.
[0076] In order to facilitate the movement of the clamping member 17, the movable ends 180 in this embodiment are set as two groups and are symmetrically distributed on both sides of the base 11, the guide shafts 24 are set as two and are respectively slidably connected to the movable ends 180 on both sides, the screw transmission mechanism is set between the two movable ends 180, and the two groups of movable ends 180 are fixedly connected to the screw slider.
[0077] Specifically, in this embodiment, the lead screw 141 is disposed between the two sets of movable ends 180. The lead screw slider is threadedly connected to the lead screw 141. The two sides of the lead screw slider are fixedly connected to the two sets of movable ends 180 via connecting plates. Each set of movable ends 180 is provided with a set of push ends 181. During installation, the two sets of push ends 181 are positioned on either side of the ultrasonic probe 4. The two sets of push ends 181 can be operated to move synchronously toward the ultrasonic probe 4 to connect with the two sides of the clamping member 17. In this embodiment, the provision of two sets of movable ends 180 and two sets of push ends 181 ensures balanced force on both sides of the clamping member 17 during installation, preventing misalignment and obstruction.
[0078] like Figures 2 to 5 As shown, in one embodiment of the movable end 180, the movable end 180 includes a movable seat 1800, the pushing end 181 further includes a third spring 1811, and the clamping member includes a push rod 1810 and a clamping ring 1812. The push rod 1810 is slidably disposed in the movable seat 1800 and can be driven to move linearly in the movable seat. The third spring 1811 is sleeved on the push rod 1810.
[0079] The front end of the push rod 1810 extends out of the movable end 180 and is fixedly connected to the clamping ring 1812. The clamping ring 1812 is used to abut against the front end surface of the clamping member 17. The rear end of the push rod 1810 extends out of the movable seat 1800.
[0080] Specifically, during installation, the rear end of push rod 1810 can be pulled outward, causing the clamping ring 1812 at the front end of push rod 1810 to move rearward, clearing space for the ultrasonic probe 4. During this process, push rod 1810 compresses third spring 1811. The ultrasonic probe 4 is then installed into the probe buckle 16, with the clamping member 17 also sleeved onto the ultrasonic probe 4. Push rod 1810 is then released. Under the action of third spring 1811, the clamping ring 1812 at the front end of push rod 1810 moves toward the ultrasonic probe 4 until it aligns with the front end of the clamping member 17. Finally, the movable base 1800 is controlled to move. During this movement, the clamping ring 1812 pushes the front end of the clamping member 17, causing it to move linearly backward on the ultrasonic probe 4 until it disengages from the probe buckle 16. After installation is complete, push rod 1810 can be pulled outward again, causing the clamping ring 1812 to disengage from the ultrasonic probe 4, facilitating removal of the ultrasonic probe 4.
[0081] like Figure 5As shown, in order to keep the clamp ring 1812 in an open state before 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 a first position, which is the open position of the clamp ring 1812.
[0082] In addition, in this embodiment, it is expected that the clamp ring 1812 can automatically close and clamp the front end of the clamping member 17 when the operating movable end 180 moves to the disassembly position.
[0083] like Figure 1a and Figure 5 As shown, a first linkage structure 15 is provided on the base 11, and 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 able to link with the locking structure 25. When the movable seat 1800 moves to the second position, the first linkage structure 15 triggers the locking structure 25 to release the clamping ring 1812. The second 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.
[0084] Specifically, before installation, movable base 1800 is in its initial position. Push rod 1810 can be manually pulled outward. When push rod 1810 is pulled to the first position, locking mechanism 25 is triggered, locking push rod 1810 in the first position. In this embodiment, the first position of push rod 1810 corresponds to the open position of clamping ring 1812. That is, when clamping ring 1812 is in this position, the intraoperative probe can be installed. Once push rod 1810 is locked in the first position, the intraoperative ultrasound system can be installed in the probe clip 16, and movable base 1800 can then be controlled to move forward.
[0085] like Figure 6 and Figure 7 As shown, when the movable base 1800 moves forward to the second position, the first linkage structure 15 on the base 11 triggers the locking structure 25 within the movable base 1800. At this time, the locking structure 25 releases the push rod 1810 under the action of the first linkage structure 15. The push rod 1810 moves inward under the action of the third spring 1811, causing the clamping ring 1812 to move toward the ultrasonic probe 4. Because the clamping ring 1812 needs to abut against the front end surface 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 base 1800 when the projection of the clamping ring 1812 on the ultrasonic probe 4 is close to the front end surface of the clamping member 17.
[0086] In this embodiment, the locking structure 25 and the first linkage structure 15 can be configured in various forms, and a mechanical structure can be used to trigger the linkage. Specifically, a slot 1813 can be provided on the push rod 1810. The locking structure 25 includes a latching rod 252 and a fourth spring 251 disposed within the movable seat 1800. The latching rod 252 is hinged within the base 11. The fourth spring 251 is connected to the latching rod 252. The first end of the latching rod 252 is engaged with the latching slot 1813.
[0087] The second end of the card rod 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 card rod 252 to rotate the card rod 252 so that the first end of the card rod 252 disengages from the slot 1813.
[0088] 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 latch rod 252. Under the action of the fourth spring 251, the first end of the latch rod 252 is locked in the slot 1813 to lock the push rod 1810. At this time, the second end of the latch rod 252 extends out of the lower end of the movable seat 1800.
[0089] As the movable base 1800 moves to the second position, the second end of the latching rod 252 gradually approaches the first linkage structure 15. After the second end of the latching rod 252 contacts the first linkage structure 15, as the movable base 1800 moves further, the latching rod 252 rotates about the hinge point, causing the first end of the latching rod 252 to gradually disengage the latching slot 1813. When the movable base 1800 reaches the second position, the first end of the latching rod 252 completely disengages the latching slot 1813. At this time, the push rod 1810, under the action of the third spring 1811, pushes the clamping ring 1812 forward and clamps it onto the ultrasound probe 4.
[0090] like Figure 5 As shown, in one embodiment, the latching rod 252 may include two vertical portions and a horizontal portion, with the two vertical portions fixed to the ends of the horizontal portion. The middle portion of the horizontal portion is hinged to the movable seat 1800 via a rotating shaft. The vertical portion at the front end of the horizontal portion is configured to engage with the latching slot 1813. The vertical portion at the rear end of the horizontal portion can extend beyond 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 portion.
[0091] In order to enable the first end of the locking rod 252 to automatically snap into the locking slot 1813 when the push rod 1810 is pulled to the first position, in this embodiment, inclined surfaces can be set at the first end of the locking rod 252 and the position on the push rod 1810 at the rear end of the locking slot 1813, and automatic locking is achieved through the cooperation of the two inclined surfaces.
[0092] On the basis of the above implementation mode, Figure 1a As shown, the first linkage structure 15 includes a linkage block fixed on the base 11, and a linkage inclined surface 150 and a linkage plane 151 are provided on the linkage block. The linkage inclined surface 150 and the linkage plane 151 are arranged in sequence along the moving direction of the moving seat 1800 toward the disassembly seat.
[0093] 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 slope 150 and a linkage plane 151. When the push rod 1810 is locked by the clamping rod 252, as the movable seat 1800 moves forward, the second end of the clamping rod 252 gradually approaches the linkage slope 150. After the second end of the clamping rod 252 contacts the linkage slope 150, as the movable seat 1800 moves further, the clamping rod 252 will rotate around the hinge point, so that the first end of the clamping rod 252 gradually falls off the clamping groove 1813 on the push rod 1810. When the second end of the clamping rod 252 moves to the linkage plane 151, the first end of the clamping rod 252 completely disengages from the clamping groove 1813 to release the clamping ring 1812, and the clamping ring 1812 will move to correspond to the front end surface of the clamping member. As the movable base 1800 moves further, the second end of the clamping rod 252 will move on the linkage plane 151 . During this process, the clamping ring 1812 pushes the clamping member 17 to move and disengage from the probe buckle 16 .
[0094] To reduce the friction between the second end of the latching rod 252 and the linkage block, a second rolling member 253 is provided at the second end of the latching rod 252 in this embodiment. The second rolling member 253 is configured to cooperate with the linkage inclined surface 150 and the linkage flat surface 151. The second rolling member 253 can be a ball bearing or a bearing, etc., and is not limited to this embodiment.
[0095] It is understood that, in addition to mechanical linkage, the locking structure 25 and the first linkage structure 15 of the present invention may also be electrically linked. Specifically, the locking structure 25 can electrically lock and release the push rod 1810, for example, by employing an electromagnetic lock. During the movement of the movable base 1800, the position of the movable base 1800 can be detected by a corresponding displacement sensor. When the movable base 1800 moves to the second position, a corresponding electrical signal is triggered, thereby controlling the locking structure 25 to release the push rod 1810.
[0096] In order to better push the clamping member 17, as Figure 5 As shown, the clamp ring 1812 in this embodiment is set to be semicircular, and the upper and lower ends of the clamp ring 1812 on both sides are provided with a first plug-in portion and a second plug-in portion that cooperate with the plug-in.
[0097] Since the positioning mechanism 19 needs to move to fix the probe buckle 16 during the disassembly process, based on the above-mentioned linkage method, in this embodiment, the positioning mechanism 19 is linked with the movement of the movable seat 1800. It is expected that when the movable seat 1800 moves to the second position, the positioning mechanism 19 can move to the position of fixing the probe buckle 16.
[0098] Therefore, if Figure 4 As shown, in this embodiment, a second linkage structure 20 is further provided on the base 11, and the second linkage structure 20 is configured to be able to link with the positioning mechanism 19 and the propulsion mechanism 18;
[0099] When the movable base 1800 moves to the second position, the second linkage structure 20 triggers the positioning mechanism to perform the action of fixing the probe buckle 16 .
[0100] Specifically, in this embodiment, when the movable base 1800 is in the initial position, the positioning mechanism 19 is also in the initial position, and the positioning mechanism 19 does not interfere with the insertion of the probe clip 16 into the disassembly slot 130. After the movable base 1800 moves to the second 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 capable of securing the probe clip 16 under the action of the second linkage structure 20. After the movable base 1800 moves backward to complete the disassembly of the clamping member 17, i.e., after the movable base 1800 moves backward a certain distance, the positioning mechanism 19 resets under the action of the second linkage structure 20, and the probe clip 16 is released.
[0101] After setting the second linkage structure 20, after locking the clamp ring 1812 to the open position, it is only necessary to control the movable seat 1800 to move forward to automatically complete the closing of the clamp ring 1812 and the fixation of the probe buckle 16 by the positioning mechanism 19, and then operate the movable seat 1800 to move backward again to complete the disassembly of the clamping member 17 and the release of the probe buckle 16.
[0102] Since the thickness of the clamping member 17 is relatively thin, when the clamping member 17 is pushed only by the rear end surface of the clamping ring 1812 and the front end surface of the clamping member 17, the clamping ring 1812 and the clamping member 17 are likely to slip, resulting in a failure in disassembly. Figure 1b As shown, in this embodiment, a positioning protrusion 18120 is provided on one end of the clamping ring 1812 close to the clamping member 17. The positioning protrusion 18120 is located on both sides of the clamping ring 1812. The positioning protrusion 18120 is used to be clamped into and fit onto the inner side of the clamping member 17 before pushing the clamping member 17 to locate the radial position of the clamping member 17.
[0103] Specifically, in this embodiment, prior to disassembly, the positioning protrusion 18120 is located in front of the clamping member 17, and the clamping member 17 and the probe clip 16 are in a locked state. To allow the positioning protrusion 18120 to engage the inner side of the clamping member 17, a clearance groove 160 is provided in the portion of the probe clip 16 that engages the clamping member 17. In one embodiment, the locked portion of the probe clip 16 includes a plurality of locking tabs, with adjacent locking tabs spaced apart to form the clearance groove 160. During installation, the clamping member 17 engages the locking tabs, thereby securing the tabs to the ultrasound probe. In another embodiment, the clearance groove 160 can be directly provided at the rear end of the probe clip 16, allowing the positioning protrusion 18120 to engage the inner side of the clamping member 17 through the clearance groove 160.
[0104] During the disassembly process, the clamp ring 1812 moves toward the clamping member 17, and the positioning protrusion 18120 is clamped into the inner side of the clamping member 17 through the avoidance groove 160, so that the clamp ring 1812 is not likely to slip off the clamping member 17 during further movement. Figure 4 As shown, the positioning mechanism 19 includes a positioning block 190 and a third elastic portion 191 , the positioning block 190 includes a blocking portion, and the blocking portion is located behind the disassembly slot 130 ;
[0105] The positioning block 190 is connected to the third elastic portion 191 and is provided on the base 11 and can move linearly along the radial direction of the ultrasonic probe 4, so that the blocking portion can move to fit the rear end surface of the probe buckle 16 under the action of the third elastic portion 191;
[0106] The movable seat 1800 is linked to the positioning block 190 through the second linkage structure 20 .
[0107] Specifically, in this embodiment, the third elastic portion 191 can utilize its elastic force to propel the positioning block 190 to move linearly along the radial direction of the ultrasonic probe 4. This allows the blocking portion on the positioning block 190 to abut against the rear end of the probe buckle 16 during disassembly, thereby overcoming the tension exerted on the probe buckle 16 during disassembly. In this embodiment, the positioning block 190 can be positioned at the rear end of the disassembly seat 13, below the disassembly slot 130. The blocking portion can be a blocking plate disposed at the upper end of the positioning block 190. The third elastic portion 191 can be a spring, and a corresponding spring mounting post can be disposed 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 movable seat 1800 is connected to the positioning block 190 via the second linkage structure 20, enabling the positioning block 190 to interlock with the movable seat 1800.
[0108] In one embodiment of the second linkage structure 20, the second linkage structure 20 may comprise a traction rope and a reel. The reel may be disposed on the movable base 1800 and connected via a torsion spring. The ends of the traction rope are connected to the reel and the positioning block 190, respectively. The movement of the positioning block 190 is controlled by the movement of the movable base 1800.
[0109] 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, and the lower end surface of the slide rail 205 is provided with a track surface, and the track surface includes a first surface 201, a second surface 202 and a third surface 203 distributed in sequence along the direction toward the disassembly seat 13, the first surface 201 is higher than the third surface 203, and the second surface 202 is provided as an inclined surface connecting the first surface 201 and the second surface 202;
[0110] The support leg 204 is fixed on the positioning block 190 . When the movable base 1800 moves to the second position, the support leg 204 contacts the first surface 201 . The blocking portion moves to fit the rear end surface of the probe buckle 16 under the action of the third elastic portion 191 .
[0111] Specifically, in this embodiment, when the movable seat 1800 is in the initial position, the support leg 204 abuts against the third surface 203 of lower height. At this time, the positioning block 190 is in the initial position and compresses the third elastic portion 191. When the movable seat 1800 moves forward from the initial position, the second surface 202 on the track surface gradually contacts the support leg 204. Since the second surface 202 is an inclined surface and the second surface 202 is connected to the first surface 201 of higher height, the support leg 204 gradually rises under the action of the third elastic portion 191 during the process of contacting the second surface 202 and causing the positioning block 190 to gradually rise. After the movable seat 1800 moves to the second position, the support leg 204 contacts the first surface 201 and slides on the first surface 201 for a distance that is consistent with the amount of movement required for the clamping member 17 to be disassembled. At this time, the support leg 204 and the positioning block 190 are located at the highest position under the action of the third elastic portion 191 , and the blocking portion on the positioning block 190 rises to fit the rear end surface of the probe buckle 16 .
[0112] During disassembly, the movable base 1800 moves backward, and the supporting legs 204 gradually move from the first surface 201 to the third surface 203 via the second surface 202 . During this process, the positioning block 190 gradually moves to the initial position.
[0113] To reduce the friction between the support leg 204 and the track surface, the third rolling member 205 is arranged on the support leg 204 in the embodiment, the third rolling member 205 is in abutment with the track surface, and the third rolling member 205 can be a bearing or a ball.
[0114] In one embodiment of the installation of the electromagnetic navigation sensor, the electromagnetic navigation sensor is installed on the probe buckle 16 through the clamping groove 1813, and thus the electromagnetic navigation sensor needs to be dismounted by removing the clamping groove 1813 from the probe buckle 16. The clamping groove 1813 is generally clamped on the inner bottom surface of the probe buckle 16, and thus to dismount the clamping groove 1813, a dismounting seat 13 is arranged in the embodiment, the dismounting seat 13 is hinged with a top rod 22, a pressing rod 21 and a top block 23 are arranged on the dismounting seat 13, the pressing rod 21 and the top block 23 correspond to the two ends of the top rod 22 respectively and can move vertically and linearly on the dismounting seat 13, the upper end of the pressing rod 21 extends out of the upper end of the dismounting seat 13, and the upper end of the top block 23 can extend out of the bottom surface of the dismounting groove 130 and be inserted into the dismounting hole of the probe buckle 16 under the pushing action of the pressing rod 21.
[0115] When dismounting, the pressing rod 21 can be pressed downward, the pressing rod 21 then presses the front end of the top rod 22 downward, the top rod 22 rotates to push the rear end of the top block 23 upward and insert the top block 23 into the dismounting hole at the lower end of the probe buckle 16, and the clamping groove 1813 is lifted to disengage the clamping groove 1813 from the probe buckle 16.
[0116] The above only describes the preferred embodiments of the utility model and is not used to limit the utility model, and the utility model can have various changes and variations for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made in the spirit and principle of the utility model should be included in the protection scope of the utility model.
