Abstract

The present invention belongs to the technical field of medical devices, and discloses a hemorrhoid ablation needle and control method for use under endoscopy, including an outer sheath assembly, a puncture needle assembly, an electrode needle assembly and a handle body, wherein the handle body has a hollow pipe that passes through the front and back, for the outer sheath assembly, the puncture needle assembly and the electrode needle assembly to pass through, and a tube body portion is formed at the front end of the handle body, and the tube body portion is used in conjunction with an endoscope, and the diameter and length of the tube body portion are both adapted to the endoscope forceps channel, and under the guidance of the endoscope, the outer sheath assembly, the puncture needle assembly and the electrode needle assembly cooperate with each other in the handle body to realize the puncture, rotation and ablation functions. The hemorrhoid ablation needle of the present invention is adapted to the endoscope forceps channel, and can enter the anus under the guidance of the endoscope, and the endoscope can be used to magnify the lesion, making the surgical field of view clearer and the positioning more accurate, which is convenient for accurate positioning of the lesion and combined treatment.
