Abstract

The invention relates to polypropylene / polylactic acid interwoven composite pelvic floor mesh and a preparation method thereof. The mesh is in a meshwork structure. Preparation of the mesh includes: weaving medical-grade polypropylene monofilaments and medical-grade polylactic acid monofilaments to obtain a mesh in the meshwork structure; flushing the mesh, naturally air-drying at normal temperature, and carrying out thermal setting, cooling, cutting and sterilizing to obtain the mesh. The mesh has the advantages such as low sense of foreign matters, high porosity, structural stability and good biocompatibility.

Description

technical field

[0001] The invention belongs to the field of composite pelvic floor patch and its preparation, in particular to a polypropylene / polylactic acid interwoven composite pelvic floor patch and a preparation method thereof. Background technique

[0002] Female pelvic floor dysfunction (PFD) is a gynecological disease characterized by stress urinary incontinence (SUI), pelvic organ prolapse (POP) and chronic pelvic pain (CPP). disease. A large number of studies have shown that pelvic floor mesh is an important pelvic floor tissue replacement, which can replace the weak and damaged pelvic floor fascia tissue. Compared with the traditional hysterectomy method, the mesh has gradually been confirmed in terms of improving the safety of the operation and improving the quality of life of patients [ACHTARIC, HISCOCKR, O'REILLYBA, et al. mesh.IntUrogynecolJPelvicFloorDysfunct,2005,16(5):389-394;LORDHE,TAYLORJD,FINNJC,etal.Arandomizedcontrolledequivalencetrialofshort-termco...
