介入手术输送系统研究进展

The delivery system used in interventional surgery: recent progress in research

介入手术是近30年发展起来的全新的治疗方式,具有创伤小、恢复快、痛苦少等优点,被认为是科技发展带来的医学革命。而作为介入医疗器械的重要组成部分,输送系统直接影响了手术过程的顺利与否。本文综述了血管内介入和非血管介入中常见器械的输送系统。重点分析了支架(球扩式支架和自膨式支架)、起搏器、瓣膜和封堵器输送系统的结构及具体使用要求。不同的介入医疗器械根据其产品结构、手术路径、组织解剖结构等方面的用途,需设计相匹配的输送系统。最后,通过对目前市场上介入手术输送系统的综合分析,提出了今后输送系统研发设计需考虑的因素,并对该领域的未来发展趋势作一展望。

Interventional surgery is a new way of treatment that has been developed in the past 30 years. It has the advantages of mini-invasive, quicker recovery and less pain. Therefore, this technique is considered to be the medical revolution brought about by the development of science and technology. As an important part of interventional medical device, the delivery system has a direct impact on the success of the operation. This paper aims to make a comprehensive review about the delivery system that is usually included in common interventional instrument package for intravascular and non-vascular intervention procedures, focusing on the structure and specific application requirement of the delivery system that are used for the implantation of stent （balloon-expansion stent and self-expanding stent）, pacemaker, valve and occluder. According to the structure of interventional medical instrument, the surgical path, the anatomical characteristics, etc. the delivery system should be specially designed so as to match the interventional medical instrument that will be used in a special interventional procedure. Finally, based on the comprehensive analysis of various interventional delivery systems that are available in the market at present, the factors that should be considered in the future research and design of delivery system are proposed, and certain expectations for its future development are discussed.
