Abstract

A surgical instrument is provided. The surgical instrument includes a housing. A movable handle is coupled to the housing and is configured to approximate a pair of jaw members toward and away from one another. A latch mechanism operably couples to the movable handle and includes one or more mechanical interfaces configured to selectively engage a corresponding mechanical interface disposed within the housing to lock and unlock the jaw members in an approximated configuration. When the movable handle is in a jammed position, the mechanical interface(s) of the latch mechanism is/are configured to deform and separate from the corresponding mechanical interface disposed within the housing when the movable handle is moved from the jammed position.
