Embodiment 1

[0039] The manufacturing process of the abdominal wall hernia repair mesh dedicated to open surgery according to the present invention will be described in detail below with a specific embodiment. Described manufacturing process specifically comprises the following steps:

[0040] 1. Solution preparation

[0041] 1.1 Materials: PLCL pellets, acetone.

[0042] 1.2 Apparatus: 1000ml volumetric flask, 250ml measuring cylinder, 250ml Erlenmeyer flask.

[0043] 1.3 Environment: Class 100,000 clean workshop

[0044] 1.4 Equipment dry heat sterilization, 165 ℃, 2 hours. Rinse with acetone before use.

[0045] 1.5 Take the PLCL pellets, open it at room temperature, pour it into a 1000ml volumetric flask, add acetone to make the volume to 1000ml, cover the bottle tightly and place it at 40°C to dissolve for 48-72 hours, shake and shake during the period, and use it as a film-making PLCL solution for later use (PLCL concentration: 0.1 g / ml).

[0046] 1.6 Take 100ml of film-making ...

Embodiment 2

[0096] 1. Solution preparation

[0097] 1.1 Materials: PLCL, MPEG2000-PLLA6000, acetone.

[0098] 1.2 Apparatus: 1000ml volumetric flask, 250ml measuring cylinder, 250ml Erlenmeyer flask.

[0099] 1.3 Environment: Class 100,000 clean workshop

[0100] 1.4 Equipment dry heat sterilization, 165 ℃, 2 hours. Rinse with acetone before use.

[0101]1.5 Prepare 10, 30 or 50 grams of MPEG2000-PLLA6000, open it at room temperature, pour it into a 1000ml volumetric flask, add acetone, cap the bottle tightly and place it at 40°C to dissolve, then add 90, 70, 50 grams of PLCL and stir to dissolve completely , and add acetone to make it to 1000mL, and use it as a film-making mixed solution (the mass ratios of PLCL and MPEG2000-PLLA6000 are 9:1, 7:3, and 1:1, respectively).

[0102] 1.6 Take 100ml of film-making mixed solution and add it to a 250ml Erlenmeyer flask, then add 100ml of acetone, cap the bottle tightly and shake well, and use it as a coating mixed solution for later use.

Abstract

The invention relates to an abdominal hernia repair mesh specially used for an open surgery, belonging to the technical field of medical consumables. The abdominal hernia repair mesh specially used for the open surgery comprises a polypropylene mesh and an absorbable membrane layer, wherein the surface of the polypropylene mesh is dipcoated with an absorbable coating, and the absorbable membrane layer is laminated on the polypropylene mesh; the area of the absorbable membrane layer is larger than that of the polypropylene mesh; the edge of the absorbable membrane layer is turned over and folded to the other side surface of the polypropylene mesh and then is fixed to form a locating bag. Compared with hot-pressing or molding by casting, the anti-adhesion patch enables polypropylene and the anti-adhesion membrane to be completely nested with each other, and microscopic examination proves no obvious boundary surface exists, so that the phenomenon of stratification does not occur. The abdominal hernia repair mesh is more easily used in the open surgery; the time of the surgery is shortened, the mesh is flatter after being implanted, the contact between the polypropylene and visceral organs such as intestinal canal and the like can be avoided to the utmost extent.

Description

technical field [0001] The invention relates to the technical field of medical consumables, and more specifically, the invention relates to an abdominal wall hernia repair mesh specially used for open surgery. Background technique [0002] A hernia is a fascial defect in a structure, such as the abdominal wall, through which an organ or part of an organ, tissue or part of a tissue can protrude. Usually it involves a weakening, bulging or actual tearing of the fascia that normally structurally contains the organ or tissue. There are many types of hernias. For example, when in the lower abdominal region, hernias often contain intra-abdominal contents, such as bowel or other tissue, that enter or pass through a defect in the abdominal wall. Mesh mesh is widely used in hernia repair. Currently commonly used hernia repair sheets are polyester mesh (such as Dacron, Mersilene) and polypropylene mesh (such as Marlex, Prolene, etc.). However, pure non-degradable mesh cannot be us...
