Valve(s) in fluid communication with tubing for aspiration or irrigation are located within the body. A locking mechanism having first and second components affixed at different points in the handset which are selectively movable relative to one another to transition between locked and unlocked positions. The first component is connected to and selectively movable relative to the cover. The second component engages a portion of the first component, causing the cover to move in an engagement direction as the first component is moved to a locked position. Movement of the cover in an engagement direction causes the valve(s) to change from a first to second position which controls the flow of fluid therethrough. An engagement surface of the second component engages and retains the first component in a locked position.
