Hot and cold ablation needle

Abstract

The invention relates to the technical field of therapy, in particular to a hot and cold ablation needle. The hot and cold ablation needle is used for solving the technical problem that in the prior art, disturbance of a handle part of an ablation needle body can be immediately transmitted to a needle tip part of the ablation needle body, and consequently a patient is affected. The hot and cold ablation needle comprises a first flow inlet pipe assembly and a first backflow pipe assembly, the first flow inlet pipe assembly and the first backflow pipe assembly are constructed to be of bent pipestructures correspondingly, thus the extension directions of the first flow inlet pipe assembly and the first backflow pipe assembly are both changed, even if sudden disturbance or vibration acts on the handle part of the ablation needle body, the situation that acting force is immediately transmitted to the needle tip part of the ablation needle body, and consequently the patient is affected is avoided, therefore, through the bent pipe structures, disturbance of unstable factors such as disturbance to the needle tip part of the ablation needle body can be reduced, and thus the therapeutic stability of the ablation needle body is improved.

Description

technical field [0001] The invention relates to the technical field of treatment, in particular to a cold and hot ablation needle. Background technique [0002] Thermothermic ablation is a surgical medical technology that uses refrigerant and heat media to eliminate target tissue. During the operation, the ablation needle is used to deliver low-temperature medium to the patient's lesion, so that the liquid refrigerant evaporates and absorbs heat, and takes away the tissue of the lesion. The heat reduces the temperature of the target ablation site, thereby destroying the diseased cells and tissues 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 rewarmed quickly. [0003] In order to facilitate production, the current cold and hot ablation needles are generally straight n...
