Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of surgical instruments, in particular to a laparoscopic hernia repair self-fixing patch insertion device. Background Art
[0002] Currently, laparoscopic transperitoneal preperitoneal repair (TAPP) is a common surgical procedure for treating inguinal hernias. During the procedure, a patch is inserted into the abdominal cavity and then fixed to the weakened area of the abdominal wall. Patches are divided into two types: traditional polypropylene patches and self-fixating patches. Patches are usually inserted through a trocar. During insertion, the patch often curls and wrinkles. Self-fixating patches are particularly prone to self-adhesion and even deformation, as they are composed of a monofilament polypropylene mesh and attached polylactic acid micro-anchors. After insertion, the adhered patch must be loosened and flattened before use, adding unnecessary manipulation and time to the surgery. Utility Model Content
[0003] In order to solve the problems mentioned in the background technology, the purpose of the present invention is to provide a laparoscopic hernia repair self-fixating patch insertion device.
[0004] In order to achieve the above objectives, the technical solution of the utility model is:

The outer sleeve is provided with a functional seam on its peripheral wall extending from one axial end to the middle. The outer sleeve is movably connected to the piston. The main hollow tube and the side hollow tube are fixedly connected to the piston. The main hollow tube is concentrically arranged with the piston, and the side hollow tube is eccentrically arranged with the piston. The center rod and the auxiliary rod are movably connected to the main hollow tube and the side hollow tube respectively. The patch partner is in the shape of a folded paper sheet. A tube sleeve is connected to the folded position of the patch partner, and the tube sleeve can be sleeved on the center rod.
[0006] Furthermore, an inner flange is provided in the port of the outer sleeve connected to the functional seam, and the inner flange can prevent the piston from escaping from the outer sleeve.
[0007] Furthermore, an outer flange is provided on the end of the outer sleeve away from the inner flange.
[0008] Furthermore, the lengths of the main hollow tube and the side hollow tube are both greater than the length of the outer sleeve, the length of the center rod is greater than the main hollow tube, the length of the auxiliary rod is greater than the side hollow tube, and the ends of the main hollow tube and the side hollow tube facing the inner flange are aligned with the piston.
[0009] Furthermore, one end of the main hollow tube away from the inner flange is connected to a crank.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.
[0016] like Figure 1-Figure 2 As shown, a laparoscopic hernia repair self-fixing patch insertion device comprises an outer sleeve 1, a piston 2, a main hollow tube 3, a side hollow tube 4, a center rod 5, an auxiliary rod 6 and a patch partner 7. A functional seam 11 extending from the front end of the outer sleeve 1 to the middle is provided on the peripheral wall of the outer sleeve 1. The outer sleeve 1 is movably connected with a piston 2, the length of the piston 2 is half the length of the outer sleeve 1, and the piston 2 is fixed with a main hollow tube 3 and a side hollow tube 4. The main hollow tube 3 is concentrically arranged with the piston 2, and the side hollow tube 4 is eccentrically arranged with the piston 2. The length of the hollow tube 4 is greater than that of the outer sleeve 1. The front ends of the main hollow tube 3 and the side hollow tube 4 are aligned with the front end of the piston 2. The center rod 5 and the auxiliary rod 6 are movably connected to the main hollow tube 3 and the side hollow tube 4 respectively. The length of the center rod 5 is greater than that of the main hollow tube 3, and the length of the auxiliary rod 6 is greater than that of the side hollow tube 4. The patch companion 7 is in the shape of a folded paper. A tube sleeve 71 is connected to the folded position of the patch companion 7, and the tube sleeve 71 can be sleeved on the center rod 5. The patch companion 7 is made of polyethylene and has the ability to restore to its original shape after deformation.
[0017] In actual use, first push the main hollow tube 3, push the piston 2 to the front end, insert the center rod 5, clamp the patch between the two pages of the patch partner 7, then put the patch partner 7 on the center rod 5 through the tube sleeve 71, and then insert the auxiliary rod 6, and then align the two pages of the patch partner 7 with the functional seam 11. Push the piston 2 together with the center rod 5, auxiliary rod 6, patch partner 7 and patch backward. After the piston 2 reaches the rear end, rotate the piston 2 through the main hollow tube 3 to roll the patch partner 7 and the patch out of the functional seam 11. Insert the cannula, then place the device into the laparoscope puncture card, pull out the auxiliary rod 6, fix the central rod 5, push the piston 2 forward, the piston 2 will push the patch partner 7 and the patch forward until they are released into the abdominal cavity, and finally pull out the device, shake the patch out of the patch partner 7 in the abdominal cavity, and take out the patch partner 7 from the puncture card. Since the patch is clamped between the two pages of the patch partner 7 before being released, it can effectively solve the problems of adhesion, folding, twisting and deformation of the self-fixing patch in laparoscopic surgery during the insertion process.
[0018] In this embodiment, an inner flange 12 is provided in the end of the outer sleeve 1 connected to the functional seam 11 , and the inner flange 12 can prevent the piston 2 from being separated from the outer sleeve 1 .
[0019] In this embodiment, an outer flange 13 is provided on the end of the outer sleeve 1 away from the inner flange 12 , so that a hand can be placed on the outer flange 13 to facilitate pushing the piston 2 .
[0020] In this embodiment, one end of the main hollow tube 3 away from the inner flange 12 is connected to a crank 31 for facilitating the rotation of the piston 2 .
[0021] In this embodiment, the center rod 5 is tension-connected in the main hollow tube 3 , which is beneficial for fixing the center rod 5 .
