  • Repair material with multi-purpose for abdominal wall hernia
    Patent number: 10350045
    Abstract: A repair material with multi-purpose for an abdominal wall hernia of the present invention relates to a technical field of medical consumables, which includes technical field of medical consumables. In the MPEG-PLLA copolymer, a molecular weight of MPEG is 2000-10000, and a molecular weight of PLLA is 3000-8000. Compared with PLCL, the repair material of the present invention is significantly improved in water absorption of the absorbable membrane to ameliorate healing effects, and a contact angle is greatly reduced. As a result, postoperative abdominal wall compliance is sufficient, which basically provides no discomfort. Therefore, compared with the PLCL, the present invention is more comfortable. In addition, the repair material of the present invention doesn't need to be heat-fitted, and polypropylene is completely fitted with the absorbable membrane, wherein no obvious boundary face is observed through a microscope, and separation never occurred.
