Method for preparing tensionless net cloth for repairing hernia

Abstract

The invention provides a method for preparing a tensionless net cloth for repairing hernia. The method comprises the following steps of: selecting medicinal polypropylene granules, assembling the polypropylene granules into a finished product by cutting and cleaning after three times of cooling, drafting, drawing and weaving processes, and sterilizing the finished product by using an ethylene oxide sterilizer for later use. The imported good-quality medicinal polypropylene granules are adopted in the method; monofilaments are woven into a mesh patch; and the patch has good biological tissue compatibility, can be quickly stuck and fixed with tissues, has no rejection reaction, has certain capability against infection, is an ideal hernia repair material, and has the same properties and functions as the imported product. The method creates a condition for clinical popularization and use, and has broad market prospect.

Description

technical field [0001] The invention relates to a medical polymer material, in particular to a preparation method of a tension-free mesh used for repairing hernia. Background technique [0002] A hernia is a disease in which an organ or tissue (usually the intestine) in the abdominal cavity leaves its normal anatomical position, protrudes from the body surface through a defect or gap in the abdominal wall through a congenital or acquired weak point. Because it is a genetic disease associated with a genetic defect or metabolic imbalance, hernia is one of the most common diseases in humans. Adult hernias are not self-healing, and surgery is the only effective treatment. Bassini first created the hernia repair named after him based on the etiology theory of inguinal hernia more than a hundred years ago (1887), emphasizing The importance of reconstructing the posterior wall of the inguinal canal, the operation is simple, easy to master, and the postoperative effect is good, so ...
