Abstract
A handheld electrocautery cutter is provided for suction, removal of body tissues and electrocauterization of tissue in a patient. The electrocautery cutter includes a distal end, a rigid cannula, a movable cutter, a cutter, a valve, a valve actuator, an electrical switch, and an electrical actuator. The rigid cannula defines a cannula interior and the cannula includes a proximal end and a distal end. The distal end of the cannula is insertible and positionable in a patient's body and the cannula defines a cannula opening adjacent the distal end to permit access to the cannula interior for capture of body tissue in the cannula interior. The movable cutter cuts tissue entering the cannula opening and the cutter actuator moves the cutter. The valve is connected to the cannula to control suction flow from the cannula interior and the valve actuator actuates the valve. The electrical switch is linked to the cannula to control mono-polar electrocautery current flowing from adjacent the distal end of the electrocautery cutter to the patient and the electrical actuator activates the electrical switch. The cannula and valve are integrated into a rigid structure to be held in a user's hand such that movement of the rigidly coupled cannula and valve by a user's hand allows the distal end of the cannula to be accurately positioned at a specific location in the patient's body. The cutter actuator, valve actuator, and electrical actuator are operable by a hand of the user as it moves the rigidly coupled valve and cannula to accurately position the distal end of the cannula in the patient's body.
