Problems solved by technology

The electrophysiological mapping catheters in the prior art are difficult to accurately record the electrical signals for the irregular structure of the heart chamber and the rough inner wall
In addition to the cramped space in the cardiac cavity, the current electrophysiological mapping catheter cannot collect data from these complex anatomical structures for the strip-like grooves formed by the comb muscles in the atrium and the loose mesh-like pits formed by the trabecular muscles in the ventricle. Therefore, the lesions cannot be accurately diagnosed through the three-dimensional mapping map given by it, which will bring troubles to physicians

Abstract

The invention discloses an inflorescence-shaped electrophysiological mapping catheter device. The inflorescence-shaped electrophysiological mapping catheter device comprises a catheter, a handle device, electrodes and a connector, wherein the catheter comprises an adjusting tube, a plurality of first branch tubes and a plurality of second branch tubes, one ends of the first branch tubes are connected with the adjusting tube, the other ends of the first branch tubes are distributed in a staggered mode and are in a divergent shape, and each first branch tube is provided with one electrode; one ends of the second branch tubes are connected with the adjusting tube, the other ends of the second branch tubes are distributed in a staggered mode and are in a divergent shape, the included angle between each second branch tube and the adjusting tube is smaller than that between each first branch tube and the adjusting tube, each second branch tube is provided with one electrode, and the handle device can adjust the bending angle of the far end of the adjusting tube. The connector is arranged on the handle device and electrically connected with the electrodes. The inflorescence-shaped electrophysiological mapping catheter device can adapt to a heart cavity with an irregular three-dimensional space, and can record electrophysiological signals of a large number of wrinkles or loose gulliesexisting on the inner surface of the heart cavity.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an inflorescence-shaped electrophysiological mapping catheter device. Background technique [0002] Atrial fibrillation is one of the most common arrhythmias in clinical practice. Electrophysiological minimally invasive surgery, as a less invasive treatment with a high cure rate, has made rapid progress in the treatment of atrial fibrillation. Electrophysiological minimally invasive interventional surgery is to first insert the mapping catheter through the venous blood vessel, push the catheter to the heart chamber, move the catheter and adjust the angle of the front end of the catheter to make the front end electrode contact the inner wall of the heart chamber, and simultaneously record the potentials of different parts of the heart . The mapping catheter is used in conjunction with the 3D mapping system to realize the 3D reconstruction of the heart. By observing the conduction s...
