A kind of hernia mesh plug prepared with modified polypropylene fiber monofilament mesh

Abstract

The invention discloses a hernia mesh plug prepared from a modified polypropylene fiber monofilament mesh cloth. The material of the hernia mesh plug is a modified polypropylene fiber monofilament mesh cloth obtained by surface treatment. The surface treatment method of the polypropylene fiber monofilament mesh cloth is firstly treated with an oxidizing agent for 40 minutes, and then surface coated with an organic solvent for 15-24 hours. The beneficial effects of the present invention are: the hernia mesh plug provided by the present invention has small incisions and less sutures when filling the hernia affected area, and its filling structure can fill the hernia affected area more conveniently and effectively than before, and is more in line with the physiological and anatomical structure of the human body, reducing the The recurrence rate of patients, meanwhile, the modified polypropylene fiber monofilament mesh cloth adopted in the present invention, the oxidant treatment can reduce the contact angle of the material by about 30%; the surface coating treatment can change the surface of the polypropylene fiber monofilament It can reduce the rejection reaction of the material. It can be seen from the experimental data that the degree of inflammation of the mesh provided by the invention is obviously better than that of untreated polypropylene monofilament fiber woven into mesh.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a hernia mesh plug prepared from modified polypropylene fiber monofilament mesh cloth. Background technique [0002] Hernia, that is, a part of a human tissue or organ leaves the original part and enters another part through a gap, defect or weak part of the human body. Most of the treatment methods are surgical treatment with regular or irregular patches, but there are many sutures, and there is a possibility of chronic pain left after surgery, and the effect varies with different locations of the affected area, and it is easy to relapse. At the same time, due to the materials used Most of them are ordinary organic materials, which are very easy to have a rejection reaction with the human body, which increases the difficulty and risk of postoperative rehabilitation. At present, there are no technical reports in the field of hernia repair surgical materials in routine operations. ...
