AN ANVIL CAP OF A MULTIPLE UMBRELLA TYPE FOR CIRCULAR STAPLERS

摘要

The present invention relates to an anvil cap (14) providing secure anastomosis in the circular staplers comprising a main body (1), a clamping arm (10) configured on said main body (1), punch section (12) and a punch surface (12.1) corresponding to said punch section (12); characterized in comprising movable inner shaft (3) on which a pulling movement is applied by means of a command wire (7), upper wings (5) which are made to open by means of the joint points (16) of said movable inner shaft (3), lower wings (2) which are made to open when said upper wings (5) apply a pressure on the lower wings (2)after they open and apply a pulling movement, and an anvil cap (14) configured upon the combination of these two-level wings.
