Suture fixer and stitching instrument

Abstract

The invention discloses a suture fixer and a stitching instrument. The suture fixer comprises a main rod body, a suture lead clamp and a baffle structure, wherein the main rod body is provided with asuture fixing end; the suture lead clamp is rotationally arranged at the suture fixing end; the suture lead clamp forms a threading channel; the suture lead clamp is further provided with a suture hooking hole communicating with the threading channel; the baffle structure is positioned at the suture fixing end; the suture lead clamp is rotated relative to the main rod body to unfold the suture lead clamp and a suture relative to the main rod body; at least a part of the main rod body, the suture lead clamp and the baffle structure form a baffle space in a surrounding manner; suture hooking pincers extend into the suture hooking hole to hook up the suture; and the baffle structure is used for baffling the suture hooking pincers from penetrating through the baffle space. The technical schemeof the invention aims to optimize fixation modes of the suture, puncture injury caused by the suture hooking pincers to organs in an abdominal cavity in the stitching process is avoided, and the security of the stitching instrument can be improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a suture fixer and a stapler with the suture fixer. Background technique [0002] Compared with traditional surgery, minimally invasive abdominal surgery has the advantages of small incision and fast recovery, so it is accepted by more and more patients. During laparoscopic surgery, multiple puncture channels with a diameter of 5 to 10 mm are usually opened in the abdomen to penetrate the abdominal wall tissue, so that surgical instruments can enter the abdominal cavity through these puncture channels to perform surgery. The puncture channel is sutured so that the wound can heal smoothly. [0003] At present, the commonly used stapler includes a suture fixer and a hook pliers used in conjunction with the suture fixer. The suture fixer includes a main rod body, a lead clip that is movably connected to one end of the main rod body, and a pull rod inside the main rod bo...

Problems solved by technology

However, this method of fixing sutures inside the abdominal cavity is unreliable, and the sutures are easy to retreat together with the suture pliers, and it is necessary to pierce the filler in the suture hole several times. If the strength is not grasped, it is very easy to puncture If it is excessive, it will cause puncture injury to the organs in the abdominal cavity. In severe cases, it may also cause medical accidents
