Abstract

A cryosurgical instrument, in particular a biopsy instrument for transbronchial biopsy, having an elongated instrument base body with a distal and proximal end, in relation to the operational position, a cooled section close to the distal end and which removes tissue, said section being designed such that surrounding biological material adheres thereto, by means of cryoadhesion, when said instrument is in use in the cooled state, and a security section which is provided at a distance from the tissue removal section and which comprises means for preventing or reducing the adhesion of biological material.
