摘要： A surgical instrument and method for indicating that a cartridge has been fired includes an end effector receiving a cartridge having at least one of a knife and a plurality of staples, a shaft assembly connected to the end effector, and a handle assembly. The handle assembly has a handle housing, a firing member configured to selectively actuate from a first position to a second position as a firing stroke, and a feedback generator operatively connected to the firing member. The firing member is configured to actuate the cartridge from an unfired cartridge position to a fired cartridge position when the firing member is actuated. The feedback generator is configured to communicate an audible sound and a visual indicia to an operator indicative of the firing member completing the firing stroke for actuating the cartridge to the fired cartridge position.

摘要： A surgical instrument and method of manipulating tissue of a patient includes a body, a shaft assembly extending distally therefrom, and an end effector extending distally from the shaft assembly and configured to receive a cartridge for manipulating tissue. The end effector has a distal end portion, a proximal end portion, a gap between the distal and proximal end portions, and a retaining pin. The retaining pin includes a distal head and is selectively movable from an open position to a locked closed position. In the open position, the retaining pin is proximally positioned such that the gap is configured to receive tissue. In the locked closed position, the retaining pin extends across the gap and is configured to capture tissue within the gap. The distal head of the retaining pin is configured engage and secure the distal end portion relative to the proximal end portion via the retaining pin.

摘要： A method for manipulating tissue of a patient includes a surgical instrument having a handle assembly, a shaft assembly, and an end effector. The method includes positioning a tissue within a gap between a cartridge and an anvil and against a guide pin to laterally position the tissue relative to the cartridge and the anvil. The method also includes moving a retaining pin from an open position to a closed position to capture the tissue and moving the cartridge toward the anvil in a closed configuration. Furthermore, the method includes inhibiting deflection of a distal end portion of the end effector wherein at least at least one of the guide pin or the retaining pin connects to the distal end portion. The method further includes forming a plurality of staples within the tissue and cutting the tissue with a knife.

摘要： A surgical instrument and method of manipulating colon tissue of a patient includes a body having a firing mechanism, a shaft assembly, and an end effector operatively connected to the firing mechanism via the shaft assembly. The end effector is configured to receive a cartridge selectively actuated by the selective manipulation of the firing mechanism. A distal end portion of the end effector includes a first end, a second end laterally opposite the first end, and a distal crest laterally positioned between the first and second ends that projects distally beyond the first and second ends. The distal end portion also includes an arcuate distal surface extending along the distal with a radius of curvature configured to be received against the pelvic bowl of the patient to position the end effector relative to colon tissue for manipulating the colon tissue with the cartridge.
