Abstract

The invention discloses a cardiac intervention ablation catheter, the catheter comprises more than two branch electrodes (5), a catheter trunk (6) and an operating handle (7), wherein, all the branch electrodes (5) are distributed in a shape of petals, the top end of each petal of branch electrode (5) is a metal electrode (12), the lower ends of the metal electrodes are provided with a temperature sensor (11), the metal electrodes (12) are connected with an examination and treatment instrument (4) through a metal wire and the temperature sensor (11) which are welded at the lower ends of the metal electrodes and a connection line (15) of the sensor passes through an insulation tube (14), a catheter trunk (6) and a handle (7) sequentially. the root part of the catheter trunk (6) is provided with a depth scale (19) and an angle scale (20), the invention can realize that the invention can be tightly affixed at the surgical site of the rugged part in the heart; the invention can realize the ring-shaped ablation under the appropriate three to five times of the rotation of the catheter.

Description

technical field [0001] The present invention relates to a medical treatment appliance, in particular to a device composed of more than two branch electrodes. In the natural state, the branch electrodes unfold like chrysanthemum petals, and can be in reliable contact with objects under a ring-shaped and uneven condition. , a cardiac interventional ablation catheter for temperature monitoring, electrical signal extraction and / or energy transmission. Background technique [0002] In fields such as electrocardiographic interventional therapy, a large number of interventional catheters are used to monitor temperature parameters of the treatment site, extract electrophysiological signals, and / or transmit therapeutic energy. Especially in the radiofrequency ablation of the heart, for the uneven parts inside the beating heart, reliable abutment and / or ring ablation are required to achieve the success of the operation. At present, there are two types of catheters used in cardiac rad...
