Hernia mesh plug prepared from modified polypropylence fiber single silk mesh

Abstract

The invention discloses a hernia mesh plug prepared from a modified polypropylence fiber single silk mesh. The hernia mesh plug is made from the modified polypropylence fiber single silk mesh which is obtained after surface treatment. The surface treatment method for the polypropylence fiber single silk mesh comprises the following steps of: treating the polypropylence fiber single silk mesh by using an oxidizing agent for 40 minutes, and coating the surface of the polypropylence fiber single silk mesh with an organic solvent for 15-24 hours. When used for filling the hernia affected part, the hernia mesh plug provided by the invention has the beneficial effects that the wound is small and the suture is less; by virtue of the filling structure of the hernia mesh plug, the hernia affected part can be filled more conveniently and effectively, the hernia mesh plug well complies with the human physiological anatomical structure, and the recurrence rate of a patient is reduced; simultaneously, as the modified polypropylence fiber single silk mesh is used, the contact angle of the material can be reduced by about 30% after the treatment by using the oxidizing agent; the surface properties of the polypropylence fiber single silk can be changed through the surface coating treatment to reduce the rejection reaction of the material; and the experimental data proves that the inflammatory response degree of the mesh provided by the invention is obviously superior to the mesh woven of the untreated polypropylence single silk fiber.

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. ...
