Abstract
A cryosurgical instrument for separating a tissue sample from a biological tissue to be treated, for purposes of biopsy. The cryosurgical instrument includes a probe for bringing a probe head up to the biological tissue and a gas line for supplying cooling gas from a gas source of a cryosurgical apparatus to the probe head. The probe head cools a limited tissue region, by means of the supplied gas, for obtaining a tissue sample. The tissue sample can be separated from the surrounding tissue when frozen onto the probe head. The instrument has a support tube in which the probe is guided and which can be moved relative to the probe in such a way that the surrounding tissue can be supported by means of the support tube during the separating of the tissue sample. The instrument also includes an accelerating device that provides a predefined force for the separating process.
