Abstract
A thermoelectric cryoprobe comprising a handle composed of two electrically insulated halves made of a material possessing high heat conduction. One end of the handle is tapered, and a semiconductor cooling thermoelement is arranged at the butt of the tapered end. The height of the thermoelement does not exceed the radius thereof. The surface of a commutation plate of the thermoelement is the working surface of the thermoelectric cryoprobe.

A thermoelectric cryoprobe, comprising:
- a handle comprising two electrically separated longitudinal half-cylinders made of a high heat conduction material;
- a semiconductor cooling thermoelement having a hot junction in contact with said two half-cylinders, said thermoelement including a commutation plate mounted on one end of said handle and in direct contact with the latter by said hot junction, the height of said thermoelement does not exceed its radius, and said commutation plate having a functional surface which is a working surface of said thermoelectric cryoprobe;
- a heat sink for removal of heat from said semiconductor cooling thermoelement, said heat sink comprising said two electrically separated longitudinal half-cylinders forming part of said handle;
- and
- means for feeding current to the longitudinal half-cylinders of said handle.
