Abstract

The invention discloses a cable type radiofrequency ablation catheter and a manufacturing method thereof. The cable type radiofrequency ablation catheter comprises a control handle, a catheter body and an electrode section, wherein the catheter body is a cable integrated type catheter body manufactured with a cable manufacturing technology, one end of the catheter body is used for being connected with the control handle, and the other end of the catheter body is used for manufacturing the electrode section. According to the cable type radiofrequency ablation catheter, multiple sets of wires are orderly arranged inside the catheter and are mutually insulated, the structure is simple, the manufacturing process is simple, using is safe, and the catheter is suitable for serving as a renal artery radiofrequency ablation catheter; meanwhile, through the arrangement of a flexible control wire, the diameter of the electrode section can be further controlled so as to be adapted to the diameters of the renal artery blood vessels of different patients, and then the adherence effect of an electrode is good and the radiofrequency ablation range is wide.

Description

technical field [0001] The invention relates to a cable type radio frequency ablation catheter and a manufacturing method of the cable type radio frequency ablation catheter, belonging to the technical field of medical devices. Background technique [0002] Radiofrequency ablation is a widely used minimally invasive medical technology. In recent years, radiofrequency ablation has been widely used in the treatment of various lesions such as the heart, cancer tumors, and even skin. It uses the characteristic that the temperature field rapidly decays near the conductor when the radio frequency energy acts on the human tissue, so that the treatment point is more concentrated, and the lesion is treated with minimally invasive treatment through a small catheter probe. [0003] Since the radiofrequency ablation operation is directly intervening in human blood vessels, the size of the catheter should be suitable for the diameter of human blood vessels. The diameter of the human re...
