Patent ID: 8703627

Claim:
An antiadhesive material comprising a gelatin film, the antiadhesive material further comprising: a reinforcing material that is made of a biodegradable polymer other than collagen and is arranged in the gelatin film, wherein the reinforcing material is a fabric body having a density in a range of 5 g/m 2 to 45 g/m 2 and a yarn threading tension in a range of 0.210 N to 200 N, and wherein the biodegradable polymer is at least one polymer selected from the group consisting of polylactic acid, lactic acid-caprolactone copolymer, polyglycolic acid, lactic acid-glycolic acid copolymer, lactic acid-ethylene glycol copolymer, polydioxanon, glycolic acid-caprolactone copolymer, glycolic acid-trimethylene carbonate copolymer, glycolic acid-dioxanon-trimethylene carbonate copolymer, chitin, chitosan, and fibrin, wherein the reinforcing material and the gelatin film are integrated due to gelation of gelatin that has intruded entirely in an internal part of the reinforcing material, and wherein the fabric body is a knitted fabric that is a twin loop knit fabric having the twin loop knit as shown in FIG. 7 .
