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.

1-14. (canceled)
A cryosurgical instrument comprising:
- an elongated instrument base body having a distal end and a proximal end;
- a cooled tissue grasping section located close to the distal end, said tissue grasping section being configured such that surrounding biological material will adhere due to cryoadhesion when the instrument is being used in a cooled state;
- and
- a safety section provided distally from the tissue grasping section, said safety section comprising means for preventing or reducing the adhesion of biological material.
A cryosurgical instrument comprising:
- an elongated instrument base body having a distal end and a proximal end;
- and
- a cooled tissue grasping section located close to the distal end, said tissue grasping section being configured such that surrounding biological material will adhere due to cryoadhesion when the instrument is being used in a cooled state,
- wherein the tissue grasping section is designed such that the cryoadhesion effect on a distal surface is substantially reduced compared to that of the peripheral region.
