目前临床电生理检查、消融、标测等所用的导管大多需要进口,价格昂贵,而且绝大部份导管不具有头端角度可调节的特点,所以在手术中往往因定位的不准确导致手术时间的延长甚至失败。为了临床与科研的需要,我们于两年前已研制出这种头端角度可调的导向电极导管,并应用于临床,现将这种导管的特点与应用情况介绍如下。一、导管的基本结构与特点导管的导向主要靠导管头端的角度,如使头端10公分扭曲的角度可调,此导管便有了可导向性。为了使此角度可调,我们设计了一个类似人工关节的结构在导管腔内,这样便使导管有了头端角度可调的功能。此种导管有如下特点: 1.导管头端的角度可从0～180°可调。此可使导管在插入血管、心脏的过程中可根据通道的弯曲度
At present, the catheters used in clinical electrophysiological examination, ablation, mapping and so on are mostly imported and expensive, and the vast majority of catheters do not have the characteristics of adjustable head-end angle. Therefore, inaccurate positioning of the catheter often leads to operation time The extension or even failure. For clinical and scientific research needs, we developed this two years ago, the tip angle of the guide electrode catheter and applied to clinical, now this catheter characteristics and applications are described below. First, the basic structure and characteristics of the catheter The catheter is mainly guided by the catheter tip end of the angle, such as head-end 10 cm twist angle adjustable, this catheter will have a guide. In order to make this angle adjustable, we designed a similar artificial joint structure in the catheter lumen, so that the catheter has a head-end angle adjustable function. Such catheters have the following characteristics: 1. Catheter head angle can be adjusted from 0 ~ 180 °. This allows the catheter insertion in the blood vessels, heart, according to the curvature of the channel
