Problems solved by technology

Chinese invention patent "Soaking cold knife device that can promote rapid heating and melting of frozen tumor tissue" (patent application number 01201762.0) Although it can be used to achieve alternating cold and heat treatment, it is a "soaking cold knife device" , "When in use, the freezing head is pre-placed in liquid nitrogen, and then it touches the tumor after taking it out", the rewarming of the freezing head is realized by the internal heating element, so there is no continuous liquid nitrogen flow to achieve continuous cold and hot alternating therapy , and is only suitable for the treatment of superficial tumors such as skin tumors, but it is completely inapplicable for tumors located in the human body, which has great limitations

Embodiment Construction

[0011] Such as figure 1 As shown, the present invention includes: an inner tube 1 , an outer tube 2 , a temperature acquisition unit 3 , a single-core shielded wire 4 , a temperature signal output wire 5 , a vacuum insulation layer 6 , and a hand-held jacket layer 7 . Its connection relationship is: the inner tube 1 is arranged in the outer tube 2, the 2 cm long part of the front end of the treatment needle is the heat transfer section 8, and the hand-held outer coat layer 7 is set on the rear end of the outer tube 2 to form the hand-held section 10. The temperature acquisition unit 3 is located inside the outer tube 2 of the heat transfer section 8 , and the temperature signal of the temperature acquisition unit 3 is drawn out from the handheld section 10 through the temperature signal output line 5 . The vacuum insulation layer 6 is sleeved on the outer tube 2 between the heat transfer section 8 and the hand-held section 10 to form the heat insulation section 9 of the treatm...

Abstract

A medical needle for treating tumor by alternative freezing and heating is composed of internal and external tubes, ttemp sampling unit, shielded single-core line, temp signal output line, insulating vacuum layer, and hand-held external sleeve layer.

Description

technical field [0001] The invention relates to a device for treating tumors, in particular to a needle-type cold and heat alternating tumor treatment head. Used in the field of medical devices. Background technique [0002] Seeking a medical method that can ensure the least damage to healthy tissues while treating tumors has been the goal that many scientific researchers and medical personnel have been striving for. With the development of science and technology, especially the progress of image technology such as nuclear magnetic resonance imaging, ultrasound imaging, etc., minimally invasive surgery such as low temperature cryosurgery and hyperthermia for tumors has begun to develop more and is becoming more and more popular. , but they still have their own shortcomings. Existing hypothermic surgery has relatively harsh conditions for completely killing tumor cells. Rabin et al. found in the study of cryogenic surgery on sheep breast cancer that the area damaged by low ...
