Abstract

A sealed surgical stapling instrument for performing a circular anastomosis stapling operation is provided.
The surgical instrument includes a stapling head assembly mounted by a curved shaft to an actuator handle assembly and incorporates an improved actuator mechanism for transmitting the required operating forces and movements from the actuator handle assembly through the curved shaft to an anvil and staple driver of the stapling head assembly. Various mechanisms for sealing the instrument are disclosed.
