1. A surgical device comprising:
a closure assembly including:
a. a movement unit configured to be connected to a movable member, the movement unit including:
i. a bar;
ii. a bar biasing member in communication with the movement unit and moving the bar;
b. a latch unit configured to be connected to a ground member, the latch unit including:
i. a hook latch that selectively receives the bar, and
ii. a latch biasing member in communication with the hook latch to selectively move the hook latch;
wherein all or a portion of the latch unit is movable relative to the ground member and all or a portion of the movement unit is movable relative to the movable member, and the latch unit and the movement unit are movable relative to each other when the latch unit and the movement unit are in contact;
wherein the bar is movably mounted to move along a prescribed path so that upon the bar and the hook latch contacting each other, during a process of locking or unlocking, the bar is displaced from a bar home position in a first direction that is transverse to the prescribed path until the bar contacts a bar stop that prevents movement in the first direction; and
wherein the hook latch is displaced from a latch home position in a second direction that is transverse to the prescribed path and opposite the first direction.
