Forceps including a double biased handle latch

A closure assembly, comprising:

• a movement unit including a bar and a bar biasing member, the movement unit configured to be operably coupled to a movable member such that the movable member is configured to move relative to a ground member to move the bar between a home position and a locked position, the bar biasing member configured to move the bar relative to the movable member, and the bar biasing member locatable at least partially within the movable member;
• and
• a latch unit configured to be operably coupled to the ground member, the latch unit including:
• a latch configured to be spaced apart from the bar when the bar is in the home position, the latch configured to selectively receive the bar when the bar is moved to the locked position;
• a window configured to receive at least a portion of the latch;
• and
• a latch biasing member, the latch biasing member locatable at least partially within the ground member, the latch biasing member in communication with the latch to selectively move the latch along at least a portion of the window;
• wherein the latch unit and the movement unit are movable relative to each other when the latch unit and the movement unit are in contact.

A closure assembly for a surgical device, comprising:

• a movement unit configured to be connected to a movable member configured to move relative to a ground member, the movement unit including:
• a bar arm configured to extend from the movable member when the movement unit is connected to the movable member;
• a bar connected to and extending from the bar arm;
• and
• a bar biasing member in communication with the movement unit and in communication with the bar arm such that the bar biasing member is configured to move the bar arm and the bar relative to the movable member;
• and
• a latch unit configured to be connected to the ground member, the latch unit including:
• a window;
• a hook latch configured to selectively receive the bar, the hook latch slidably engageable with the window;
• and
• a latch biasing member in communication with the hook latch to selectively move the hook latch along at least a portion of the window;
• wherein the bar is movable relative to the hook latch between a home position where the bar is spaced apart from the hook latch and a locked position where the bar contacts a locking feature of the hook latch;
• wherein actuating the movable member a first time moves the bar from the home position to the locked position;
• and
• wherein the latch unit and the movement unit are movable relative to each other when the latch unit and the movement unit are in contact.
