Abstract
An insulated, compact, mobile crysosurgical instrument is provided that has no moving parts in contact with a liquefied gas coolant retained in an insulated container. Upon interrupting normal venting from the container, the liquefied gas coolant will build up a pressure in the container which may be increased by a squeeze pressure device. That pressure will cause the liquefied gas coolant to spray from a nozzle until normal venting is restored.
