Anastomotic/occlusion reinforcing and repairing composite member as well as preparation and application method thereof

The invention relates to the technical field of medical equipment and discloses an anastomotic/occlusion reinforcing and repairing composite member which comprises a reinforcing and repairing part, a protection part and a connection line, wherein the two ends of the reinforcing and repairing part are detachably connected by the connection line; and the protection part penetrates into a space enclosed by the two ends of the reinforcing and repairing part. The invention also provides a preparation and application method of the anastomotic/occlusion reinforcing and repairing composite member. The anastomotic/occlusion reinforcing and repairing composite member disclosed by the invention can provide enough strength to the to-be-treated tissue to prevent suture tearing; with low or nearly no immunogenicity, the composite member realizes relatively low pathogenicity and high biocompatibility, while a large number of beneficial components promoting tissue repairing are maintained.
