IMPROVEMENTS IN OR RELATING TO CRYOGENIC PROBES

摘要

A cryogenic probe comprises a probe body (30) and a tip (10), the body and the tip having co-operating screw threads for releasably securing the tip to the body. The probe tip is largely formed of plastics material, whilst the head portion (14) of the tip as used for surgery is formed from brass. When a cryosurgical operation has been completed the tip (10) may be removed from the probe body and, due to the constructional materials used, the tip is rendered disposable. A new tip (10) can be used for any subsequent operation, thus obviating the risk of cross-contamination without the need for sterilisation procedures.
