Abstract

The invention relates to an ablation device. The ablation device comprises a sheathing canal, a plurality of annular electrodes and a driving mechanism, wherein the sheathing canal is provided with a main cavity channel and a plurality of containing cavity channels communicating with the main cavity channel, the containing cavity channels are mutually independent, and the end, away from the main cavity channel, of each containing cavity channel is an open end; the annular electrodes are slidably connected with the containing cavity channels in a one-to-one correspondence manner, so that each annular electrode has a first position and a second position which are mutually switched, and when the annular electrodes are located at the first position, the annular electrodes extend out of the containing cavity channels; when the annular electrodes are located at the second position, the annular electrodes are accommodated in the containing cavity channels; and the driving mechanism is connected with the annular electrodes and is used for driving the annular electrodes to slide relative to the sheathing canal. The contact area of the ablation electrode and the tissue can be enlarged, so that the ablation efficiency and the operation success rate are improved.

Description

technical field [0001] The present invention relates to the field of medical equipment, in particular to an ablation device. Background technique [0002] At present, the use of radiofrequency fusion technology to treat asthma is gradually recognized by doctors and patients. The distal end of the bronchial thermoforming catheter is a radio frequency electrode, which uses heat to thin the hypertrophic airway smooth muscle on the airway wall, thereby reducing the contraction of the airway during asthma attacks, and at the same time reducing the frequency and severity of asthma attacks. [0003] After research, it is found that the existing ablation devices have the following disadvantages: [0004] The contact area between the ablation electrode and the tissue is small, and the ablation efficiency is low and the effect is poor. Contents of the invention [0005] The purpose of the present invention is to provide an ablation device, which can increase the contact area betwe...
