Ring sleeve ligature-taking-out type surgical instrument

Abstract

The invention relates to the technical field of medical instruments, in particular to a ring sleeve ligature-taking-out type surgical instrument. The ring sleeve ligature-taking-out type surgical instrument comprises a needle rod, a needle core, a guide line and a ligature, the needle rod comprises a hollow rod body, one end of the rod body is a puncture end used for puncturing the abdominal wall, a threading hole is formed in the rod body, a ligature taking-out ring is arranged at one end of the guide line, the needle core is inserted into the needle rod, when passing through the threading hole, the needle core penetrates into the ligature taking-out ring to fix the guide line and the needle rod, the diameter of the ligature is smaller than the inner diameter of the needle rod, and the ligature can penetrate into the needle rod and penetrate out of the threading hole. The ring sleeve ligature-taking-out type surgical instrument is simple in structure, the needle rod and the needle core are both in hook-free design, it is guaranteed that the abdominal wall is not prone to being scratched in the operation process, and the abdominal wall only needs to be punctured once when the surgical instrument is used; and the ligature is taken out of the abdominal wall in a manner of sleeving the line with the ligature taking-out ring, the original operation manner of hooking a line with a hook is replaced, the operation is more convenient and reliable, and the tissue is prevented from being hooked.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a loop-and-wire surgical instrument. Background technique [0002] A hernia means that a certain organ or tissue in the human body leaves its normal anatomical position and enters another part through a congenital or acquired weak point, defect or hole. Common hernias include umbilical hernia, direct inguinal hernia, indirect hernia, incisional hernia, surgical recurrence hernia, linea alba hernia, femoral hernia, etc. In the current laparoscopic pediatric hernia surgery, two incisions, punctures and cards are required to establish two operating channels. The hernia needle enters through a small incision in the skin at the projection point on the top of the inner ring mouth and punctures the abdominal wall. The needle with thread enters the abdominal wall and leaves the ligature in the abdominal wall. After the hernia needle is withdrawn from the body, another croche...

AI Technical Summary

Problems solved by technology

This method can achieve one puncture, but the process of hooking the ligation thread with a hook needle is difficult to operate, the hook thread is difficult, and the hook thread is easy to fall off, resulting in ligation failure, repeated puncture increases surgical complications, and prolongs the operation time. For a considerable number of children, the vas deferens and spermatic cord blood vessels are not easy to bypass, and it is necessary to increase the operation hole to help pull the abdominal wall to increase the operation space in front of the abdominal wall, which increases the trauma of the children, and the multi-operation hole affects the appearance
