可操纵导管在神经介入治疗中的研究进展

Progression of steerable catheter systems in neurointerventional therapy

近年来,血管内介入治疗因其创伤小、恢复快的优势,已经成为治疗脑血管疾病的一种重要手段。导管作为介入治疗重要的手术器械,常常需要通过精确控制头端,以通过血管迂曲的位置。传统导管存在着头端形状固定、近端力矩传导受限、操控困难等缺点,这增加了患者介入手术的并发症发生风险,且延长了手术暴露时间。随着材料学和工程学的飞速发展,可操纵导管开始应用于临床介入治疗,使精准“控弯”成为可能。该文系统性阐述了可操纵导管的分类,着重介绍其在神经介入治疗领域的运用,并对可操纵导管的未来发展进行展望。

In recent years,endovascular intervention therapy has gained popularity due to its advantages of minimal trauma and quick recovery,and become an essential method for treating cerebrovascular diseases.As a crucial surgical instrument in interventional therapy,catheters often require precise control of their tips to navigate through tortuous positions.Traditional catheters have shortages of fixed tip shapes,limited proximal torque transmission,and difficulty of manipulation,increasing the risk of complications during interventional procedures and prolonging surgical exposure time.With the rapid development of materials science and engineering,steerable catheter systems have become the spotlight of interventional physicians,making precise“bend control”possible.This article systematically explained the classification of steerable catheter systems,focusing on their application in neurointerventional therapy,and provided an outlook on the future development of steerable catheters.
