Antiadhesive material
First Claim
1. 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/m2 to 45 g/m2 and a yarn threading tension in a range of 0.210 N to 200 N, andwherein 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, andwherein the fabric body is a knitted fabric that is a twin loop knit fabric having the twin loop knit as shown in FIG. 7.

Abstract
An antiadhesive material that is excellent in biocompatibility and bioabsorbability, as well as excellent strength in suturing and bonding, is provided. A reinforcing material 12 made of a biodegradable polymer is placed in a gelatin solution so that the reinforcing material 12 is impregnated with the solution, and the gelatin is caused to gelate and dried. By so doing, an antiadhesive material in which a gelatin film 11 and the reinforcing material 12 are integrated is obtained. The reinforcing material 12 preferably is arranged in a portion of the gelatin film 11 to be subjected to suturing, and preferably is arranged along a periphery of the gelatin film 11. The gelatin film 11 preferably is a cross-linked gelatin film, and the reinforcing material 12 preferably is a nonwoven fabric.
