Embodiment Construction

[0068] The present invention will be further described below with reference to the accompanying drawings.

[0069] like figure 1 As shown, the present invention provides a cold-heat ablation device, comprising an ablation device 1 and a transmission device 2, the second end of the transmission device 2 is used for connecting with a composite cold-heat ablation system (not shown). The cold working medium or the hot working medium in the composite cold and heat ablation system is delivered to the ablation apparatus 1 through the transmission device 2, so that the tissue in the target area can be treated with cold and heat ablation. In order to facilitate the connection and disassembly between the ablation device 1 and the transmission device 2 and reduce the operation steps of the doctor, a rotatable and movable quick-connect interface assembly 26 is provided on the first end of the transmission device 2 . The second end extends into the quick-connect interface assembly 26 and ...

Abstract

The invention relates to a cold and hot ablation device, relates to the technical field of cold and hot ablation operations, and is used for improving the operation convenience. The cold and hot ablation device comprises an ablation instrument and a transmission device, and locking of the transmission device and the ablation instrument can be achieved by rotating a quick connection interface assembly on the transmission device; on the contrary, during unlocking, the transmission device and the ablation instrument can be unlocked by reversely rotating the quick connection interface assembly, so that the combination and disassembly of the transmission device and the ablation instrument are quicker and more convenient.

Description

technical field [0001] The present invention relates to the technical field of thermal ablation surgery, in particular to a thermal ablation device. Background technique [0002] Cold and heat ablation is a surgical technique that uses cold and hot working fluids to eliminate target tissue. During the operation, the cold working medium in the composite cold and heat ablation system will be delivered to the treatment area of ​​the treatment device for freezing operation. It evaporates and absorbs heat, takes away the heat of the lesion tissue corresponding to the treatment area, and reduces the temperature of the target ablation site, thereby destroying the diseased cell tissue to achieve the purpose of treatment. After the freezing is completed, the composite cold-heat ablation system delivers a hot working medium to the treatment area of ​​the treatment device, which instantly releases a large amount of heat, so that the treatment area can be quickly rewarmed. [0003] The...
