Abstract:
1. A surgical stapling device comprising: a body having a pivotable trigger; an approximation mechanism including at least one clamp slide member, the approximation mechanism operably associated with the trigger such that movement of the trigger from a non-compressed position to a compressed position effects movement of the at least one clamp slide member distally from a retracted position to an advanced position; a pawl member positioned adjacent the trigger and positioned to retain the trigger in the compressed position subsequent to advancement of a thrust bar; a release mechanism including a release button and a release member, wherein the release button is positioned to effect movement of the at least one clamp slide member from the advanced position to the retracted position and the release member is positioned to engage the pawl member to facilitate movement of the trigger from the compressed position to the non-compressed position; and a pin pusher, the pin pusher having a pair of legs, each leg having a contoured profile and a rib extending therefrom, wherein the pin pusher has a reduced mass, thereby requiring a reduced actuation force to advance the pin pusher distally.
