Abstract
A surgical instrument adapted for applying a plurality of surgical fasteners to body tissue includes a frame having a proximal end and a distal end, with a handle positioned at the proximal end and an end effector positioned at the distal end. The end effector is shaped and dimensioned for supporting a cartridge module. A firing mechanism is associated with the end effector and the cartridge module for selective actuation. The end effector has a radius of curvature optimized for a trans-anal resection such that the end effector has a curvature of at most approximately a 40 mm diameter.

A surgical instrument adapted for applying a plurality of surgical fasteners to body tissue, the surgical instrument comprising:
- a frame having a proximal end and a distal end, with a handle positioned at the proximal end and an end effector positioned at the distal end;
- the end effector being shaped and dimensioned for supporting a replaceable cartridge module including a cartridge housing coupled to an anvil;
- a firing mechanism is associated with the end effector and the cartridge module for selective actuation;
- and
- wherein the end effector has a radius of curvature optimized for a trans-anal resection such that the end effector has a curvature of at most approximately a 40 mm diameter.
A surgical kit adapted for the performance of trans-anal resection, the surgical kit comprising:
- a surgical instrument comprising a frame having a proximal end and a distal end, with a handle positioned at the proximal end and an end effector positioned at the distal end, the end effector being shaped and dimensioned for supporting a replaceable cartridge module including a cartridge housing coupled to an anvil, a firing mechanism is associated with the end effector and the cartridge module for selective actuation, and wherein the end effector has a radius of curvature optimized for a trans-anal resection such that the end effector has a curvature of at most approximately a 40 mm diameter;
