Hand-held cryosurgical probe system

摘要

An improved portable, hand-held cryosurgical probe system (1) having easily changeable probes (29) and cryogen sources (22) wherein the cryogen can be provided in pre-charged cylinders (22) mountable on the hand-held unit (2) and/or supplied from remote sources, and which is capable of serving a plurality of probes via a multi-probe adaptor (31). The present invention provides the flexibility of easily changeable probes and cryogen sources in a lightweight hand unit whereby different cryogen may be employed at different stages within a procedure, or the cryogens may be mixed to vary the effective freeze capacity.
