1. A cryosurgical probe for providing an adjustable freeze zone, comprising:

  • an actuator housing assembly, comprising;

    a) an actuator housing having an elongated central opening therethrough, said actuator housing having a proximal end portion and a distal end portion;

    b) a delivery system for a cryogenic fluid, including a first end secured to said proximal end portion of said actuator housing; and

    , c) an insulation layer having a proximal portion securely attached to said proximal end portion of said actuator housing; and

    , an actuator assembly, comprising;

    a) a rotatable actuator having a portion thereof contained within said actuator housing, said rotatable actuator being rotatable relative to said actuator housing; and

    , b) a cryosurgical shaft assembly securely attached to said rotatable actuator, said insulation layer extending along an inner surface of said cryosurgical shaft to define insulated portions of said cryosurgical shaft and uninsulated portions, the relative disposition of insulated and uninsulated portions of said cryosurgical shaft assembly defining at least one freeze zone which is adjustable by relative rotation between said rotatable actuator and said actuator housing.
