Puncture suture hooking device applied to tension-free laparoscopic hernia repair

Abstract

The invention provides a puncture suture hooking device applied to tension-free laparoscopic hernia repair, belongs to the technical field of postoperative puncture suturing devices and solves the technical problem that suture hooking after tension-free laparoscopic hernia repair is difficult. According to the scheme, an oblique cutting edge is arranged at the head of a puncture sheath, and a clamping strip is symmetrically arranged at the tail of the puncture sheath; a suture hooking device body is arranged in the puncture sheath in a penetrating manner, a suture hooking arm and a suture clamping arm are hinged to the head of a telescopic handle, a torsion spring is arranged between inner sides of an included angle of the suture hooking arm and the suture clamping arm, a suture hooking slot is circuitously formed in the tail end of the suture hooking arm towards the inner side, and the head of the suture hooking arm is round and blunt; a pressing plate is arranged at the tail part of the telescopic handle and outside the clamping strip; a reset spring is arranged between the inner wall of the head of the puncture sheath and the outer wall of the tail of the telescopic handle. The device is simple in structure, convenient to operate and high in precision, a suture is not prone to fall off, and requirements of tension-free laparoscopic hernia repair can be met well.

Description

technical field [0001] The invention belongs to the technical field of postoperative puncture and suture devices, and in particular relates to a puncture and suturing device applied to laparoscopic incisional hernia tension-free repair. Background technique [0002] Abdominal wall incisional hernia is an abdominal wall hernia caused by poor healing of the aponeurotic layer that plays a major supporting role after abdominal surgery. The incidence rate is 2.0% to 11.0%. There are many reasons for abdominal wall incisional hernia, such as incision infection, incision dehiscence, postoperative severe cough, etc., can lead to the occurrence of incisional hernia. The most common symptom of incisional hernia in the abdominal wall is that there is a mass at the incision of the original abdominal operation, which protrudes when exerting force, and shrinks or disappears when resting on the back. Surgery is the only effective way to heal an incisional hernia, and the sooner it is trea...
