Problems solved by technology

[0003] The existing hot and cold ablation needles are disposable devices, and the parts cannot be replaced. After one use, the ablation needle needs to be scrapped as a whole, so the cost is high

Embodiment Construction

[0084] The present invention will be further described below with reference to the accompanying drawings.

[0085] The present invention provides a hot and cold ablation needle system, comprising an ablation needle 1 and a transmission device 2 , and the ablation needle 1 is rotatably connected to the transmission device 2 through a quick connection interface assembly 26 . The ablation needle 1 may be a straight needle or an ablation needle having a right angle.

[0086] The present invention will be described in detail below by taking an ablation needle having a right angle as an example.

[0087] The ablation needle 1 includes a replaceable needle assembly 10 , an inflow and return flow assembly 11 , and a vacuum layer assembly 12 penetrated by the inflow and return flow assembly 11 . Wherein, the inlet and outlet components 11 are pipes with right angles. The first end (front end) of the inlet and outlet assembly 11 protrudes from the underside of the vacuum layer assembl...

Abstract

The invention relates to a hot and cold ablation needle system, which relates to the technical field of cold and hot ablation surgery, and is used for reducing the cost of the cold and hot ablation needle system. The cold and hot ablation needle system of the present invention includes an ablation needle and a transmission device, the ablation needle is rotatably connected with the transmission device through a quick-connect interface assembly, and the ablation needle includes a replaceable needle head assembly, an inflow and return flow assembly, and a The vacuum layer assembly through which the inlet and outlet assemblies pass through, because the replaceable needle head assembly and the vacuum layer assembly are detachably connected, so after one treatment is over, the replaceable needle head assembly is disassembled for scrap treatment, and the inlet and outlet assemblies and the vacuum layer assembly are disassembled. Layer components are reusable for sterilization. Therefore, in the ablation needle of the present invention, only the replaceable needle head assembly is a one-time-use component, while the inflow and return flow assembly and the vacuum layer assembly are reusable components, so that the cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of thermal ablation surgery, in particular to a thermal ablation needle system. Background technique [0002] Cold-thermal ablation is a surgical technique that uses refrigerant and heat to eliminate target tissue. During the operation, a transmission device is used to connect the cryogenic cryosurgery system and the ablation needle to deliver the cryogenic medium to the patient's lesion (in this paper, liquid nitrogen is used. For example), to absorb heat through the evaporation of the liquid refrigerant, take away the heat of the lesion tissue, reduce the temperature of the target ablation site, and destroy the lesion cell tissue to achieve the purpose of treatment. After the freezing is completed, by controlling the high-temperature heat medium steam to reach the treatment site of the ablation needle, a large amount of heat is released instantly, so that the treatment area can be quickly rewarmed. The ab...
