Problems solved by technology

However, the existing adjustable bend catheters are only a single adjustable bend. Therefore, due to differences in the size or shape of the heart structure, adjustable bend catheters with different bends are required. If the bend shape of the catheter chosen by the doctor is not suitable, it needs to be replaced with other specifications. , resulting in equipment waste and multiple traumas to patients

Abstract

The invention provides an electrophysiologic catheter with multilevel adjustable bends. The electrophysiologic catheter comprises a first-level adjustable bend section, a second-level adjustable bendsection, a handle, a first pull wire, a second pull wire and a plurality of guide wires, the first-level adjustable bend section comprises a first pipeline and a head electrode arranged at a far end of the first pipeline, two passageways are arranged in the first pipeline along the length direction of the same, the second-level adjustable bend section comprises a second pipeline, a far end of thesecond pipeline is connected with a near end of the first pipeline, three passageways are arranged in the second pipeline along the length direction of the same, two of the three passageways of the second pipeline are communicated with the two passageways of the first pipeline, and at least one ring electrode is arranged on an outer wall of each of the first pipeline and the second pipeline. The electrophysiologic catheter with multilevel adjustable bends is capable of adapting to all heart structures in one specification, so that operation is enabled to be more convenient.

Description

technical field [0001] The present application relates to the technical field of a medical catheter, in particular to a mapping / ablation catheter used in arrhythmia surgery. Background technique [0002] The electrophysiological catheter is used to stimulate / map the electrophysiological activity in the heart and perform radiofrequency ablation on the lesion. For example, atrial tachycardia is a common arrhythmia. The lesion is then radiofrequency ablated with an electrophysiological radiofrequency ablation catheter to make the lesion disappear. [0003] In electrophysiological catheters, catheters with adjustable head ends have already appeared, and the distal end of the catheter can be repeatedly bent at different angles by manipulating the handle to adapt to different physiological and anatomical shapes. However, the existing adjustable bend catheters are only a single adjustable bend. Therefore, due to differences in the size or shape of the heart structure, adjustable b...
