Forceps including a pre-loaded handle latch

A closure assembly for a surgical device comprising:

• a latch unit including:
• a hook latch having a home position;
• a forward bias constraint;
• a rearward bias constraint;
• and
• a bias member operably coupled to the forward bias constraint and the rearward bias constraint so that the bias member has a pre-load when the hook latch is in the home position;
• and
• a movement unit including a bar that is movable relative to the latch unit so that the bar is movable in a prescribed motion into contact with the latch unit to create a locked state;
• wherein the hook latch is movable by the bar in a first direction away from the home position and in a second direction away from the home position.
