DISTAL TIP FEATURES FOR END EFFECTOR OF SURGICAL INSTRUMENT

摘要

An apparatus comprises a body, a shaft, and an end effector that is operable to compress, staple, and cut tissue. The end effector comprises and anvil and a cartridge. A longitudinal axis intersects the distal tip of the anvil when the anvil is in a closed position. The cartridge defines a sight line extending along a distal surface of the cartridge from a first side of the cartridge toward the anvil. The first side of the cartridge is opposite to the anvil. The distal surface of the cartridge is neither parallel to nor perpendicular to the longitudinal axis. The sight line intersects the longitudinal axis near the distal tip when the anvil is in the closed position. A segment of the sight line and a segment the longitudinal axis define an angle ?. The angle ? is larger than 90º.
