Abstract

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.
