Preparation method of self-made mesh plug for totally extraperitoneal hernia repair surgery through laparoscope

Abstract

The invention provides a preparation method of a self-made mesh plug for totally extraperitoneal hernia repair surgery through a laparoscope. The preparation method of the self-made mesh plug for the totally extraperitoneal hernia repair surgery through the laparoscope comprises the steps that (1) meshed polypropylene braided fabric is cut into meshes in a preset shape; (2) the cut meshes are arranged in a tapered and radial mode, the opening of the meshes is downward, and one ends of the meshes are sewed to be fixed in a bundling mode through a medical silk thread to be of a flat-top umbrella tip structure. The form, outside the abdominal cavity, of the mesh plug is of a long-handle rib structure, the top of the mesh plug is of the flat-top umbrella tip structure, when the mesh plug contracts, the mesh plug is of an unopened long-handle umbrella structure, bundling is carried out through the medical silk thread, and the integral shape of the mesh plug before being opened is of a cigarette shape, and the diameter of the cigarette is smaller than 1cm. The mesh plug can make up for transversalis fascia in a completely matched mode, and accords with the mechanics principle of the body structure, and according to the mechanics principle of the body structure, the higher the abdominal pressure is, the firmer the repaired position can be, the worry of relapse of a patient is removed, postoperative recovery is rapid, pain does not exist, and good practicability is achieved.

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 at present, and inguinal hernias with a large hernia sac (large defect > 10 cm) still have the risk of incomplete repair or even recurrence
