The present invention relates to a tubular suture reinforcement material suitable for use in automatic suturing devices that are widely used in surgical operations, etc. More specifically, the present invention relates to a tubular suture reinforcement material with which a tubular shape is easily obtained to thereby increase its productivity, and removal of thread is easily achieved. The present invention provides a tubular suture reinforcement material for an automatic suturing device formed by stacking two sheet-like materials and sewing together both ends of the two sheet-like materials using two chain stitches (intralooping stitches) each thread end at each sewing end is suitably extended, and the thread end is passed through an anterior loop continuous to the thread end, thereby preventing the thread from unraveling.

Suture reinforement material for automatic suturing device

A medical film that is excellent in biocompatibility and bioabsorbability and has an excellent strength in suturing and bonding is provided. A reinforcing materialmade of a biodegradable polymer is placed in a gelatin solution so as to allow the solution to infiltrate in the reinforcing materialand then the gelatin is dried. This allows the gelatin that has infiltrated entirely in an internal part of the reinforcing materialto gel, thereby forming a gelatin film. Thus, a medical filmin which the reinforcing materialand the gelatin filmare integrated is obtained. The gelatin filmpreferably is a cross-linked gelatin film.
