Surgical staple for tissue

摘要

The surgical staple (1A-C) has a circular spiral formed of metallic wire. It extends on a complete spiral which is augmented over part of its length. The staple can have a barbed end (28). The staple can have a guide tube (13) extended towards the front by an inwardly curved section with a guide channel (18). At least a section of metal wire moves in the guide tube. A pusher (9) moves the wire section towards the distal end of the guide tube.
