1. A surgical device, comprising:
- a housing having a trigger movably coupled thereto;
an elongate shaft extending from the housing with opposed jaws formed on a distal end thereof and movable between an open position and a closed position; and
a camming assembly disposed within the housing and the elongate shaft and coupled to the trigger, the camming assembly being adapted to apply a closing force to the jaws upon actuation of the trigger to move the jaws from the open position toward the closed position, and the camming assembly being adapted to transfer the closing force to an overload mechanism disposed within the housing when the closing force is greater than a resistance of the overload mechanism, wherein the resistance of the overload mechanism correlates to a force required to move the jaws from the open position toward the closed position.
