Problems solved by technology

At present, the mesh plug type hernia repair patch is generally formed by heat-pressing polypropylene mesh through a copper mold. This method requires a set of copper molds for each mesh plug type hernia patch, and uses a hot press for hot pressing. Not only the process is cumbersome, but also labor intensive
At the same time, it is easy to produce eccentricity and pleating, and the scrap rate is high

Abstract

A preparation process of a mesh plug type patch belongs to the technical field of hernia repair patches, and in particular relates to a preparation process of a mesh plug type patch. It is characterized in that it includes the following steps: step 1, cutting the petal-shaped polypropylene mesh: cutting the polypropylene mesh into petal-shaped polypropylene mesh; step 2, processing the hot-pressing forming device: the hot-pressing forming device includes a base, the base The fixing holes are arranged on the base; the fixing holes are arranged vertically and horizontally on the base, and a shaping device is movably arranged on the fixing hole; 3. Heating and shaping: heating at 120°C-180°C for 90min-150min to set the shape; step 4, cooling and moulding: after cooling to 20°C-35°C, take out; step 5, sterilization of the packaged product: sterilize with ethylene oxide . The invention has the positive effects of simple process, low labor intensity and low scrap rate.

Description

technical field [0001] The invention belongs to the technical field of hernia repair patches, in particular to a preparation process of a mesh plug type patch. Background technique [0002] A hernia is a part of a human tissue or organ that leaves its original location and enters another location through a gap, defect or weakness in the body. At present, artificial materials are generally used for tension-free hernia repair. This method can reduce postoperative pain, and has the advantages of fast recovery and low recurrence rate. At present, the mesh plug type hernia repair patch is generally formed by heat-pressing polypropylene mesh through a copper mold. This method requires a set of copper molds for each mesh plug type hernia patch, and uses a hot press for hot pressing. Not only the process is cumbersome, but also labor intensive. At the same time, it is easy to produce eccentricity and pleating, and the scrap rate is high. Contents of the invention [0003] The p...
