ABSTRACT:
The invention concerns a cryosurgical instrument with a probe for cooling limited zones of biological tissues, of which the thermally well-conducting tip has a hollow interior cross-section, into which a supply conduit connects with a constricted exit gap, through which a gas for cooling of the tip by means of the Joule-Thomson effect can be supplied by flow through the exit gap and can be led away therefrom through a coaxial discharge conduit open eventually to the atmosphere, the instrument also being provided with a device for control of the temperature of the probe tip.
