Abstract
A lavage for suction and removal of body tissues in a patient comprises a shield formed to include an opening, a cannula defining a cannula interior, the cannula having proximal end and a distal end. The distal end is insertable and positionable in a patient's body. The cannula defines a cannula opening to permit access to the cannula interior for the capture of body tissue in the cannula interior. The cannula is positioned to lie in the opening formed in the shield. An instrument is coupled to the cannula. A shield actuator is adapted to be engaged by a user, the shield actuator being coupled to the shield to move the shield relative to the cannula between a first position covering the instrument and a second position exposing the instrument. A valve is connected to the cannula for independent actuation to control irrigation and vacuum within the cannula. The cannula and valve are integrated into a rigid structure to be held in a user's hand and the valve and shield actuator are operable by the hand of the user that moves the rigidly coupled valve and cannula.
