摘要： A cryosurgery device for dispensing a liquid refrigerant from a container having a valve stem extending outwardly therefrom. The device includes an actuator adapted to seat on the valve stem of the container in order to depress the valve stem to release the refrigerant from the container. The actuator includes an inner passageway having opposed ends disposed therein, one of the ends of the passageway being in fluid communication with the valve stem. An applicator tube is mounted to the actuator at the other end of the inner passageway. A cap is disposed on the top of the container. The actuator is movably positioned on the cap and a shield is attached to the cap to completely receiving the applicator tube. Liquid refrigerant can only be dispensed when the actuator is positioned properly and the applicator tube is disposed within the shield means.
