[Self-contained neurosurgical cryoprobe]

A cryoprobe with an interchangeable container (vessel) holding the cryoprobe has been designed, this enabling it to dispense with the use of hoses to deliver the coolant to and remove it from the Dewar vessel and the vacuum pump. The cryogenic action provided for by a single ampoule lasts 5 minutes. The small diameter of the cryoprobe makes for a minimal traumatization of the surrounding structures, while the absence of connecting hoses makes for its easy handling.
