Abstract
A surgical instrument includes a first jaw, a second jaw, a cutting member, and at least one compression element. The cutting member includes a cutting edge and is configured to translate with respect to the first jaw between a retracted position and a fully advanced position. The at least one compression element extends distally from the cutting member, wherein the at least one compression element is configured to contact the first jaw such that the first jaw rotates with respect to the second jaw between an open configuration and a closed configuration when the cutting member translates with respect to the first jaw, wherein the at least one compression element comprises a rotatable member, and wherein the rotatable member is configured to be advanced ahead of the cutting edge as the cutting member translates to the fully advanced position.
