Abstract

An end effector for use by a surgeon to staple an anatomical structure of a patient during a minimally invasive procedure includes an anvil and a cartridge. The ends of the cartridge are coupled to the ends of the anvil. Each of the anvil and the cartridge is insertable through a trocar. The end effector is operable from outside the patient. A stapling device includes the end effector coupled to a manipulator via a shaft. The manipulator is accessible to the surgeon. The surgeon uses a clamping mechanism to selectively move the anvil and the cartridge to clamp the anatomical structure. A flexible member extends through the shaft and is coupled to at least one of the anvil and the cartridge and to the clamping mechanism. Operating the clamping mechanism withdraws the flexible member (46) from the end effector and clamps the anatomical structure between the anvil and the cartridge.
