Abstract

An anvil bushing for use with a surgical circular stapler used to perform an anastomosis. The anvil bushing is mounted to the anvil shaft of the stapler. The bushing has a tubular member having an axial pathway therethrough.
The tubular member has a proximal end, a distal end and an exterior surface. A first flange member having a first diameter is mounted to the distal end of the tubular member. A second flange member having a second diameter is mounted to the proximal end of the tubular member. The second diameter is larger than the first diameter. Legs for locating the bushing on an anvil shaft extend axially from the first flange member. Tissue notches are contained in the second flange member.
