外科用締付け機構
Document Type and Number:
Japanese Patent JP4044653
Kind Code:
B2
Abstract:
A surgical stapling instrument which has an elongated staple cartridge and anvil is disclosed. The anvil is movable relative to the cartridge from rearward to forward positions for insertion of tissue between these two components and clamping the tissue, respectively. A pair of spaced-apart ribs protrude from the anvil, and when the anvil is moved from its rearward to forward positions, these ribs are received into and slide within a groove embedded on the surface of the cartridge. In this manner, misalignment of the anvil and cartridge when tissue is being clamped is prevented or appreciably reduced, therefore reducing the chances of misforming the staples when the instrument is fired. The alignment features also act as tissue abutment surfaces to prevent the migration of tissue into a region where tissue is transected but not stapled.
