Preparation method of self-made mesh plug for laparoscopic complete extraperitoneal hernia repair

Abstract

The invention provides a method for preparing a mesh plug used in laparoscopic complete extraperitoneal hernia repair. The preparation steps include: step 1: cutting a polypropylene mesh braid into a mesh of a predetermined shape; step 2: cutting the above-mentioned The cut meshes are arranged radially in a conical shape with the opening downward ， A section of it was sutured and fixed with medical silk thread, forming a flat-topped umbrella-tip structure. The net plug provided by the present invention has a long-handled umbrella bone structure outside the abdominal cavity, and its top forms a flat-top umbrella tip structure, which shrinks and closes to form an unopened long-handled umbrella structure, which is bound with medical silk threads. The overall shape is one before opening. A cigarette with a diameter of less than 1 cm. The mesh plug involved in the present invention can completely fit and compensate for the transverse fascia, and conforms to the mechanical principles of human body structure—the greater the abdominal pressure, the tighter the repaired part, the patient is free from the worries of recurrence, and the postoperative recovery is fast and painless, so it is very suitable for practical.

Description

technical field [0001] The invention relates to a medical mesh plug and a preparation method thereof, in particular to a mesh plug for laparoscopic complete extraperitoneal hernia repair and a preparation method thereof. Background technique [0002] A certain organ or tissue in the body leaves the normal anatomical part and enters another part through a congenital or acquired weak point, defect or hole, which is called a hernia. Most hernias occur in the abdomen, and abdominal hernias are mostly external abdominal hernias. An external abdominal hernia is formed when the viscera or tissues in the abdominal cavity, together with the peritoneal wall, protrude to the body surface through weak points or pores in the abdominal wall. [0003] Hernia is a common and frequently-occurring disease in general surgery, and clinical practice has officially confirmed that surgery is the only way to cure hernia. There are many types of hernia surgery, but there are two types: tension her...

Problems solved by technology

Because the two are separated from each other, both the deep mesh plug and the upper plain sheet must be sutured and fixed, which shows obvious defects in the design of the mesh plug structure: 1. Excessive sutures may damage nerve branches and cause postoperative pain ; 2. The suture may cut the tissue and lose effective fixation. Clinically, the mesh plug often moves outside the body or into the abdominal cavity, resulting in hernia recurrence or other serious complications; 3. The inner valve of the existing mesh plug is very soft , the tip is inward, and the inability to withstand the pressure from the abdominal cavity may cause the mesh plug to turn outward and recur, which also makes it necessary to suture it

[0011]However, laparoscopic total extraperitoneal hernia repair (TEP) can only be applied to small and medium-sized hernias, and those with large hernia sacs (larger defects >10cm) Inguinal hernias are still at risk of incomplete repair or even recurrence
