摘要：
A surgical instrument includes a housing, an end effector, a movable handle, and a drive assembly. The movable handle includes first and second cantilever spring arms and is movable relative to the housing between a spaced-apart position and an approximated position. The first cantilever spring arm is flexed upon movement of the movable handle from the spaced-apart position towards the approximated position to bias the movable handle towards the spaced-apart position. The drive assembly is operably coupled between the movable handle and the end effector such that movement of the movable handle from the spaced-apart position towards the approximated position moves the end effector from an open position towards a clamping position for clamping tissue. The second cantilever spring arm is flexed upon application of a threshold pressure to tissue clamped by the end effector to control an amount of pressure applied to tissue clamped by the end effector.
