pivot lock arrangements for locking an end actuator in a pivot position in response to the actuation of a jaw closure system

摘要

The present invention relates to a surgical instrument including a surgical end actuator that is pivoted with respect to the elongate drive shaft. the end actuator comprises a first jaw and a second jaw. The second jaw is movable between an open position and closed positions when a closing member is moved in a closing direction. a pivot lock is configured to move from a locked configuration in which the end actuator is prevented from pivoting and an unlocked configuration in which the end actuator is pivotable. The pivot lock is configured to move from the locked configuration to the unlocked configuration when the closing member is moved from the open position in the closing direction.
