Abstract

An ablation needle water tank sealing structure is characterized in that a water tank (1), a water tank cover plate (2), a nut (9) and a rod sleeve (10) are included; the water tank (1) and the water tank cover plate (2) are in sealed connection; the rod sleeve (10) stretches into the water tank (1); the nut (9) is arranged between the rod sleeve (10) and the water tank (1); the nut (9) is in threaded connection with the water tank (1); and a rod sleeve sealing ring (8) is arranged at the connecting position of the nut (9) and the water tank (1). According to the ablation needle water tank sealing structure, the welding process is simplified, the weight of the water tank is reduced, the sealing reliability is increased, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a sealing structure of an ablation needle water tank on an ablation needle used in the medical industry, which is characterized by simple process and reliable sealing. Background technique [0002] At present, the sealing structure of the ablation needle water tank used in the medical industry is generally sealed with a metal water tank and soldered. The problem is that the quality of the water tank seal is guaranteed by the soldering proficiency of the workers, and there are many welding processes and low production efficiency. , and the defect rate is also high, resulting in increased production costs and unreliable product performance. Contents of the invention [0003] The purpose of the present invention is to address the above defects, provide a sealing structure for the ablation needle water tank, simplify the welding process, reduce the weight of the water tank, increase the reliability of the seal, and improve the pr...
