Abstract

The invention discloses a freezing-heating tool which comprises a body, a heat insulating jacket, a tool bit, a first thermocouple, a radio-frequency hyperthermia antenna, an argon pipeline, a throttling nozzle and a gas backflow cavity, wherein the body consists of a tool handle, a tool rod and a tool shell. The tool shell peripherally surrounds the tool rod and the tool bit, one end of the tool rod is connected with the tool handle, and the other end of the tool rod is connected with the tool bit. The argon pipeline is positioned in the tool rod, one end of the throttling nozzle is connected with the argon pipeline, and the other end of the throttling nozzle is positioned in the tool bit. The heat insulating jacket is inlayed to the inner periphery of a non-therapeutic section of the tool rod, a free space formed by the argon pipeline and the heat insulating jacket inlayed to the inner periphery of the tool rod is the gas backflow cavity, a part of the radio-frequency hyperthermia antenna penetrates out of the tool bit, and the first thermocouple is arranged in the tool bit. Using the freezing-heating tool for surgeries is small in surgical trauma, free of side effects and low in cost, and patients can recover quickly, do not need to be hospitalized, and can leave as long as treatment is completed.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically, relates to a hot and cold knife. Background technique [0002] At present, people's living environment continues to deteriorate, the incidence of malignant tumors continues to increase, and presents a younger trend. Traditional surgical resection involves large trauma, heavy bleeding, slow recovery and long hospital stay. Radiotherapy and chemotherapy kill cancer cells as well as normal cells and immune cells. Traditional therapy not only has a low success rate, but also seriously affects the normal life of patients, and most people lose their ability to work. Contents of the invention [0003] In view of this, the present invention provides a cold and hot knife to reduce trauma to the patient and is suitable for treating tumors in different stages. [0004] In order to solve the above technical problems, the technical solution adopted in the present invent...
