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.
Claims8
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
- a superconducting needle mounted on said barrel, wherein said superconducting needle includes a hollow body 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, said superconducting needle having a contacting end portion received within said receiving space of said barrel, and a freezing end extending out of said barrel, said contacting end portion and said freezing end being sealed fluidly so that no coolant medium enters into said hollow body.
