A compound motion cutting device for cutting a work piece includes a tubular member having first and second ends, a pair of operating members and a drive rod having first and second ends and extending longitudinally into the tubular member. One of the operating members is secured to the first end of the tubular member and the first end of the drive rod is secured to the other of the operating members. An anvil is supported proximate the second end of the tubular member and includes a surface for supporting the work piece and a slot extending through the support surface. A cutting member includes a first end pivotally attached to the second end of the drive rod and a cam slot extending laterally therethrough. A pin is supported proximate the second end of the tubular member an extends through the cam slot in the cutting member. Movement of the operating members relative to each other in one direction causes the drive rod to move the cutting member in a first longitudinal direction and the pin and cutting member cam slot cooperate to simultaneously rotate the cutting member toward the anvil and to extend at least partially into the anvil slot to cut the work piece with a combined longitudinal and rotational slicing motion.

An improved surgical instrument is provided for applying surgical fasteners, such as staples, to human tissue which is particularly suited for applying one or more rows of fasteners across a tissue lumen. The surgical instrument can be used in thoracic and abdominal surgical procedures where access to the surgical site is restricted. The surgical instrument includes an articulated fastener applying assembly mounted on a rotatable and flexible support shaft assembly to provide more convenient access to restricted surgical sites. The fastener applying assembly has a compact construction including a fixed jaw which supports a fastener cartridge and a movable jaw which supports an anvil for clamping the tissue therebetween. The fastener applying assembly includes a pin placement mechanism which is actuated by the movable jaw to control the movement of a tissue retaining pin on the fixed jaw. A dual cam mechanism is provided for driving the fasteners into the tissue clamped between the anvil and the fastener cartridge.

The improved endoscopic instrument of the present invention includes handles, a shaft and an end effectors. The handle is capable of adjustment to accommodate variations in hand size, and grip style. The handle is also adjustable relative to the shaft for use in a variety of medical procedures. In addition, the control linkages for the end effector of the improved endoscopic instrument of the present invention do not directly contact the patient thereby enabling the instrument to be easily cleaned, sterilized and reused.
