Description

Special special-shaped structure absorbable patch under laparoscope and use method

Technical Field

The invention relates to a medical instrument, in particular to a special-shaped structure absorbable patch special for a laparoscope and a using method thereof.

Background

The laparoscopic surgery is a newly developed minimally invasive method and is an inevitable trend for the development of the future surgical method. With the rapid advance of industrial manufacturing technology, the fusion of related disciplines lays a firm foundation for the development of new technology and new method, and the more and more skillful operation of doctors makes many of the past open operations replaced by the intracavitary operations, thereby greatly increasing the operation selection opportunities. In laparoscopic surgery (minimally invasive surgery), a wound of 0.5-1.5cm is cut in the waist of a patient, and a pipe-shaped working channel is inserted, so that doctors and patients perform surgery through the working channel by using an elongated surgical instrument. Most of common surgical operations, laparoscopic operations, can be performed. Such as appendectomy, gastric and duodenal ulcer perforation repair, hernia repair, colectomy, splenectomy, adrenal gland resection and the like.

The application is mainly directed to hernia repair, most of which require hernia patches, especially for the elderly, where the abdominal wall is weak.
