Abstract

The invention relates to the technical field of medical instruments, in particular to a renal artery microwave ablation needle. According to the specific technical scheme, the renal artery microwave ablation needle comprises an outer tube with one closed end and one open end, a needle tube arranged in the outer tube in a sleeved mode and a cable arranged in the needle tube, an electrode adjusting device is arranged in the outer tube and close to the closed end of the outer tube, and an electrode is fixed to the electrode adjusting device. The side wall of the outer tube is provided with an arc-shaped hole for the electrode to stretch out, one end of the needle tube is provided with a circular-truncated-cone-shaped connector, and the circular-truncated-cone-shaped connector is matched with an electrode adjusting device. And under the action of the circular-truncated-cone-shaped connector, the electrode gradually extends out of the outer pipe. The problem that the distance between the electrode and the inner wall of the renal artery cannot be adjusted in real time in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a renal artery microwave ablation needle. Background technique [0002] Clinical studies have found that the regulation of renal nerves can significantly reduce resistant hypertension. In the prior art, renal artery ablation is mostly used, and the electrode catheter is sent into a specific part of the renal artery, and radio frequency current is released to cause local coagulation necrosis of the sympathetic nerve of the renal artery, thereby achieving the interventional technique of denervation. However, due to individual differences, there are certain differences in the diameter of the renal artery and the location of the sympathetic nerve in different people. However, in the prior art, the diameter of the electrode on the ablation catheter is fixed, so that it cannot well adapt to the patient's renal artery environment, and cannot cope with the changing environment i...
