    • A cryosurgery device includes an aerosol container holding a liquid refrigerant and having a valve and a stem extending out therefrom; an actuator seated on the stem and including an outlet tube for receiving released refrigerant from the container; a hub mounted on the container and including slots therein; and a base having a central opening for receiving the hub, the base including aligning projections that enter the slots in the hub to engage and apply pressure to the actuator to cause the actuator to depress the stem and release refrigerant into the base. The container may further contain an applicator tube mounted to the hub in fluid communication with the outlet tube with a porous tip mounted to a distal end of the applicator tube for receiving the refrigerant and, being chilled thereby, applied to a skin lesion to be treated.
