Abstract
An overstroke mechanism for use with a surgical instrument includes an overstroke sleeve, an overstroke biasing element, a spindle, an outer shaft, and an overstroke pin. A first condition of the overstroke mechanism is configured to prevent a predetermined closure force from acting on the jaw members of the surgical instrument when a stroke is provided by a handle assembly of the surgical instrument that is greater than the predetermined closure force. A second condition of the overstroke mechanism is configured to prevent a further predetermined closure force from acting on the jaw members of the surgical instrument when the jaw members are approximated on an obstruction.
