ABSTRACT:
A circular stapler for performing hemorrhoidal operations is disclosed. The circular stapler includes an anvil, a stapler head and a shaft which movably supports the anvil in relation to the stapler head between open and closed positions. The stapler includes at least one displacing member, each of which is arbitrarily and/or independently displaceable along the shaft. Each of the at least one displacing members has a first end configured to engage a pursestring suture and a second end which extends through the body, e.g., the neck of the stapler. The displacing member is arbitrarily displaceable along the shaft. In one embodiment, two independently displaceable displacing members are provided. In another embodiment, the at least one displacing member is at least partially embedded in the shaft.
