Stitching instrument for laparoscopic high ligation of hernial sac

Abstract

A stitching instrument for laparoscopic high ligation of the hernial sac comprises a suture needle, wherein the suture needle comprises an outer suture needle and an inner threading needle core which are in mutual sliding sleeve connection, a thread drawing hook is arranged at the head of one end of the inner threading needle core, a thread feeding hook is arranged on the inner threading needle core in the direction opposite to the thread drawing hook, a paired hook is formed by the thread feeding hook and the thread drawing hook, and the outer size of the paired hook is matched with the inner diameter of the outer suture needle. The stitching instrument is simple to operate and safe in suturing and saves operation time.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to a laparoscopic hernia sac high-position ligation stapler. Background technique [0002] The commonly used method of laparoscopically modified high-level ligation of the hernia sac is to establish a pneumoperitoneum, incise the skin 1mm from the projection point of the top body surface of the inner ring opening of the inguinal canal, and insert a straight needle into the abdominal wall from the projection point of the top body surface of the inner ring opening to the inner ring ring. The outer layer of the peritoneum on the top of the mouth is on one side of the hernia ring mouth, surrounds the inner side of the inner ring mouth, sneaks in the extraperitoneal space to the bottom of the inner ring (note that it crosses the vas deferens and testicular blood vessels), sutures half a circle or more than half a circle first, and the needle tip punctures the peritoneum to th...

Problems solved by technology

[0003] Disadvantage 1. The suture used to ligate the hernia sac requires a suture of No. 7 or above for a firm ligation, and it is difficult to penetrate the needle hole, especially when the end of the line left in the abdominal cavity is inserted into the suture needle through the laparoscopic operation of the grasper clamp In the pinhole of the needle, the suture needle exits from the original needle entry point, and the suture thread is brought out. Because the suture at this end is wetted by body fluids in the abdominal cavity, the thread end is rough when it first penetrates the needle hole, and this step is all With the help of operating instruments, some young doctors are not very proficient in operating instruments, and the blood in the tissue during the second suturing process of the suture needle is more difficult, time-consuming and energy-consuming.

[0004] Disadvantage 2. The increase in operation and anesthesia time not only increases the risk of operation and anesthesia, but also increases the economic burden of patients

[0005] Disadvantage 3. During the suturing process, it is required to sneak around the inner side of the inner ring mouth in the extraperitoneal space to the bottom of the inner ring. Sometimes, because the inner ring mouth is affected by the friction and adhesion of the contents of the hernia, the gap is not obvious, and the needle is forced to pass through the vas deferens and the vas deferens. The danger of testicular blood vessels, the needle can not complete the suture
