Abstract

The present invention relates to a cold-heat alternative oncology therapy system whose temperature-rising and temperature-lowering rate can be controlled. Said system includes the following components: liquid nitrogen transferring pipe, high pressure liquid nitrogen Dewar's container, low-temperature electromagnetic valve, needle cold-heat alternative therapeutic head, gas-liquid separation device, radio frequency generation device, temperature collection device and control system. Said invention makes the low-temperature operating knife and radio frequency thermotherapy be combined together so as to raise killing rate of malignant tumor.

Description

technical field [0001] The invention relates to equipment in the technical field of medical devices, in particular to an alternating cold and heat tumor treatment system using liquid nitrogen as a refrigerant and radio frequency heating as a heat source with controllable heating and cooling rates. Background technique [0002] As the incidence of malignant tumors increases year by year, the threat to human health is increasing. Traditional treatment methods such as surgery, radiotherapy, chemotherapy, etc. damage, and the success rate of treatment still needs to be further improved. With the development of science and technology, especially the advancement of image technology such as nuclear magnetic resonance imaging and ultrasound imaging, minimally invasive surgery such as low-temperature cryosurgery and hyperthermia for tumors has begun to develop more and is becoming more and more popular. Welcome, but they still have their flaws. Existing hypothermic surgery has rela...
