Abstract

A surgical instrument can comprise a first jaw, a second jaw comprising a fastener cartridge, and a closing system. The closing system can comprise a closure member configured to engage the first jaw and move the first jaw toward the second jaw. A pivot can pivotably couple the first jaw to the second jaw. The closure member can engage the first jaw at a location which is distal with respect to the pivot. The closure member and the first jaw can include a cam pin/cam slot arrangement which increases the leverage or mechanical advantage that the closure member applies to the first jaw as the first jaw is moved from an open position to a closed position. The surgical instrument can further comprise a first motor configured to operate the closing system and a second motor configured to operate a firing system configured to eject fasteners from the fastener cartridge.
