Abstract
A therapeutic freezing device includes a barrel and a superconducting needle. The barrel defines a receiving space adapted to receive a coolant medium. The superconducting needle is mounted on the barrel and is adapted to contact the coolant medium so that the low-temperature of the coolant medium is transferred to the superconducting layer. The superconducting needle includes a superconductive material.

A therapeutic freezing device to be used in combination with a coolant medium and insertable into an abnormal tissue of a patient to freeze and destroy the tissue, comprising:
- a barrel defining a receiving space adapted to receive the coolant medium and having a coolant medium entrance end;
- and
- a superconducting needle mounted on said barrel and adapted to contact the coolant medium so that the low-temperature of the coolant medium is transferred to said superconducting needle, said superconducting needle including a superconductive material.
A superconducting needle for use in a therapeutic freezing device, comprising:
- a hollow body made of a conductive material;
- and
- a superconducting layer made of a superconductive material, disposed in said hollow body, and forming a superconductor lining on an inner wall surface of said hollow body.
A therapeutic freezing method, comprising the steps of:
- inserting a superconducting needle into a target site of an abnormal tissue of a patient;
- detecting and observing depth to which the superconducting needle must be inserted, and guiding the superconducting needle to reach said depth;
- contacting a coolant medium with the superconducting needle to lower the temperature of the superconducting needle;
- and
- contacting the superconducting needle with the tissue to freeze and destroy the tissue without contact between the coolant medium and the tissue.
