Abstract
The FTRD described comprises a removable cartridge body that contains a new load of staples and a new blade for use in the FTRD. The cartridge body can be removed and replaced with a new one once the staples have been used. Rotation of a main shaft by the physician causes the staples to be fired and the blade to be moved along a pre determined path to cut the stapled tissue. Tactile and audible feedback is given to the physician when the stapling phase is complete and the cutting phase is to begin.
