CRYODESTRUCTOR Russian patent published in 2021 - IPC A61B17/00 

FIELD: medical equipment.

SUBSTANCE: invention relates to medical equipment designed for a controlled process of destruction of biological tissues in the human brain during surgery. A panel computer and an industrial programmable logic controller are installed in the body of the device, a double-circuit refrigeration machine is used as a source of cold, while the tanks of the heat exchanger of the refrigerant of the lower stage of the refrigeration machine are equipped with internal spiral hydraulic lines, an emergency pneumatic button is introduced, and the cryoprobe has a base surface, a thermal insulation area, flexible connection to the device body and temperature sensor.

EFFECT: exclusion of constant replenishment of the refrigerant, automatic control of the supply of coolant to the freezing area using a cryoprobe of a special design with a heat-insulating area, ensuring freezing without time limits and monitoring the area of freezing of biological tissues in the human brain.
