[0027] Example 1

[0028] The present invention provides a pelvic floor puncture guide with multiple compatibility, such as Figures 1-4 As shown, it includes: a handle 1 and a puncture device, a locking screw 2 is provided on one side of the handle 1, a socket hole 3 is provided inside one end of the handle 1, the puncture device includes a puncture rod 4, one end of the puncture rod 4 is inserted into the socket hole 3, the puncture rod 4 is detachably connected to the inner wall of the socket hole 3 through a connecting mechanism, the puncture rod 4 extends to the outside of the socket hole 3 away from one end of the handle 1 and is provided with a fixed block 5, a puncture hook 6 is provided on the side of the fixed block 5 away from the handle 1, two threading holes 7 are provided on the puncture hook 6, a sliding rod 8 is slidably provided on the handle 1, a wire hook puncture head 9 is provided on the end of the sliding rod 8 away from the handle 1, and a wire hook groove is provided on the wire hook puncture head 9.

[0029] The working principle and beneficial effects of the above technical solution are as follows: a sliding rod 8 is slidably arranged on the handle 1, a line hooking puncture head 9 is arranged at the end of the sliding rod 8, a line hooking groove is arranged on the side wall of the line hooking puncture head 9, and the puncture line can be hooked through the line hooking groove. The puncture device as a whole is detachably connected to the handle 1. Specifically, one end of the puncture rod 4 is inserted into the plug hole 3 and is connected to the inner wall of the plug hole 3 through a connecting mechanism. A fixing block 5 and a puncture hook 6 are sequentially arranged at the other end of the puncture rod 4. The puncture hook 6 is arc-shaped and is provided on the puncture hook 6. The two threading holes 7 are used to pass the two ends of the puncture wire through the two threading holes 7 respectively, and then the two ends of the puncture wire are simultaneously wrapped around the locking screw 2 on the outside of the handle 1, and the locking screw 2 is rotated and tightened to tighten the puncture wire. Then, the puncture hook 6 is inserted into the human tissue to fix the medical device (such as a patch) and the human tissue together. Then, the sliding rod 8 is pushed to the puncture hook 6, the puncture wire is hooked through the wire hook groove, and the sliding rod 8 is pulled back to hook the puncture wire out of the body, and then a knot can be tied. In this solution, the puncture rod 4 is detachably connected to the inner wall of the plug hole 3. After the puncture rod 4 is separated from the plug hole 3, different puncture devices can be replaced. Different puncture devices have threading holes 7 corresponding to different types of puncture wires. By replacing the puncture device, the aperture of the threading hole 7 is adjusted, so that the puncture guide is compatible with different types of puncture wires, thereby achieving the guidance of different types of puncture wires. Compared with replacing the puncture guide as a whole, only the puncture device needs to be replaced in this solution, which reduces the cost of use.

[0030] Example 2

[0031] On the basis of the above embodiment 1, Figure 2 As shown, the connecting mechanism includes a snap-in hole 10 and a snap-in rod 11. The snap-in hole 10 is provided in the puncture rod 4. A sliding hole communicating with the plug-in hole 3 is provided in the handle 1. The snap-in rod 11 is slidably provided in the sliding hole. One end of the snap-in rod 11 is inserted into the snap-in hole 10 and snap-fitted with the snap-in hole 10. The other end of the snap-in rod 11 extends to the outside of the handle 1. A spring 12 is sleeved on the outside of the snap-in rod 11. One end of the spring 12 is connected to the outer wall of the handle 1, and the other end of the spring 12 is connected to the end of the snap-in rod 11 away from the plug-in hole 3.

[0032] A guiding slope is provided on the side of the clamping rod 11 close to the fixing block 5;

[0033] A pull ring 13 is provided at one end of the clamping rod 11 away from the handle 1;

[0034] An anti-slip cover is provided outside the pull ring 13 .

[0035] The working principle and beneficial effects of the above technical solution are as follows: when installing the puncture device, one end of the puncture rod 4 is inserted into the clamping hole 10. Since the side wall of the clamping rod 11 is provided with a guiding inclined surface, when the puncture rod 4 contacts the guiding inclined surface, the clamping rod 11 can be pushed outward, and the spring 12 is gradually stretched until the end of the clamping rod 11 contacts the outer wall of the puncture rod 4. Then, as the puncture rod 4 continues to be inserted, the clamping rod 11 is aligned with the clamping hole 10. Under the action of the spring 12, the clamping rod 11 is inserted into the clamping hole 10. At this time, the clamping connection between the clamping rod 11 and the clamping hole 10 is completed, and the clamping rod 11 cannot be pulled out from the insertion hole 3. After the puncture device is installed and it is necessary to replace the puncture device, two fingers are inserted into the pull ring 13, and then the pull ring 13 is pulled. The pull ring 13 drives the clamping rod 11 to move, so that the clamping rod 11 is separated from the clamping hole 10. At this time, the puncture rod 4 can be pulled out from the plug hole 3, so as to facilitate the replacement of puncture devices with different threading holes 7. An anti-slip sleeve is provided on the outside of the pull ring 13 to improve the anti-slip performance of the pull ring 13 and avoid it from slipping out during the pulling process. There are two clamping rods 11. The puncture rod 4 can only be pulled out by pulling the two pull rings 13 at the same time, avoiding misoperation by the user and improving the reliability of the connection mechanism.

[0036] Example 3

[0037] On the basis of Example 1 or 2, as Figures 1-4 As shown, a positioning plate 14 is provided on the outside of the puncture rod 4 .

[0038] The working principle and beneficial effects of the above technical solution are as follows: when the clamping rod 11 is just clamped into the clamping hole 10, the positioning plate 14 contacts the outside of the handle 1, and the position of the puncture rod 4 can be determined through the positioning plate 14, thereby improving the accuracy and reliability of the clamping between the clamping rod 11 and the clamping hole 10.

[0039] Example 4

[0040] On the basis of any one of Examples 1-3, Figure 3 As shown, a positioning key 15 is provided on the inner wall of the plug hole 3 , and a positioning groove 16 is provided on the outer wall of one end of the puncture rod 4 close to the handle 1 , and the positioning groove 16 is adapted to the positioning key 15 .

[0041] The working principle and beneficial effects of the above technical solution are as follows: the positioning groove 16 is adapted to the positioning key 15. When installing the puncture rod 4, the positioning groove 16 is first aligned with the positioning key 15 in the plug-in hole 3, and then the puncture rod 4 is inserted, which ensures that the puncture rod 4 is accurately inserted and prevents the puncture rod 4 from rotating in the plug-in hole 3, thereby improving the stability of the installation of the puncture rod 4.

[0042] Example 5

[0043] On the basis of any one of Examples 1-4, Figure 1 As shown, a plurality of push-pull blocks 17 are provided on the sliding rod 8;

[0044] A limit block 18 is provided on the puncture rod 4 and is located between the fixed block 5 and the push-pull block 17 . A through hole is provided in the limit block 18 , and the outer wall of the sliding rod 8 is slidably connected to the inner wall of the through hole.

[0045] The working principle and beneficial effects of the above technical solution are as follows: the push-pull block 17 facilitates pushing and pulling the sliding rod 8, and a limit block 18 is provided on the puncture rod 4. The limit block 18 limits the push-pull block 17 to prevent the sliding rod 8 from sliding too far and injuring the patient, thereby improving safety.

[0046] Example 6

[0047] On the basis of any one of Examples 1-5, the puncture hook 6 and the fixing block 5 are an integrally formed structure.

[0048] The working principle and beneficial effects of the above technical solution are as follows: the puncture hook 6 and the fixing block 5 are designed as an integral part, which improves the reliability of the connection between the puncture hook 6 and the fixing block 5.
