Abstract
The invention relates to a liquid-nitrogen driving cold and hot minimally invasive cutter system, which belongs to the field of medical appliances. The liquid-nitrogen driving cold and hot minimally invasive cutter system comprises a warm water tank, an electric heater, warm water, a water suction pipe, a liquid-nitrogen Dewar bottle, liquid nitrogen, a liquid-nitrogen suction pipe, a nitrogen gas pressure balance pipe, a liquid supply pipe, a liquid return pipe, a water return valve, a water supply valve, a nitrogen blow washing valve, a liquid-nitrogen supply valve, a safety valve, a pressure meter and a water storage tank. The liquid nitrogen is filled into the liquid-nitrogen Dewar bottle, the upper part of the liquid-nitrogen Dewar bottle is filled with the nitrogen gas, and the pressure of the liquid-nitrogen Dewar bottle is regulated and controlled by the safety valve. Because of the nitrogen gas pressure balance pipe, the pressure of the warm water tank and the pressure of the liquid-nitrogen Dewar bottle are identical. When the water supply valve and the water return valve are opened, the warm water flows into the liquid supply pipe through the water suction pipe to flow to a cutter head, and the water flows from the liquid return pipe to be discharged to the water storage tank. When the liquid-nitrogen supply valve and the water return valve are opened, the liquid nitrogen is sent into the liquid supply pipe through the liquid-nitrogen suction pipe and flows to the cutter head to be evaporated, the temperature of the cutter head is lowered to 196 DEG C below zero, and then, the liquid nitrogen is discharged into the atmosphere from the water return valve through the liquid return pipe, so the goal of automatically supplying cold and supplying heat for a minimally invasive cutter is realized.
