一种用于胸腰椎前路减压环锯的研制与应用

摘要

The electric grinder or osteotome technology applied in the decompression operation of thoracolumbar side anterior approach generates high temperature and causes severe damage on patients' local tissue,in addition,it has great difficulty in operation and takes a long operation time.In view of this,this study researched a trepan for anterior decompression which is applicable to anterior lateral decompression operation.The trepan for decompression of thoracolumbar anterior approach was consisted of a trepan,a control handle and a positioning rod.Through repeated simulation experiments and 28 cases of clinical application,satisfactory results were received.This trepan had advantages of simple structure,easy manufacture and low cost;and can be disassembled and assembled,which was convenient for carrying and easy operation in practical application.It could effectively prevent damages on thoracic and lumbar spinal cord and nerves in surgery.It could not only be used in trauma surgery,orthopedic and spine surgery,but also suitable for surgery in tough field conditions like field battle and disaster relief.%鉴于现有侧前方胸腰椎减压手术所采用电动磨钻或骨刀技术所产生的高温对患者局部组织损伤较重,并且存在操作难度较大,手术时间长等不足,本研究研制了一种适用于行侧前方减压手术的前路减压环锯.该胸腰椎前路减压环锯由环锯、手柄和定位杆组成.通过重复模拟实验及28例临床手术应用,收到满意效果.该环锯结构简单,制造简便,成本低廉,具有拆卸与组装的特点,方便携带,在实际应用中便于操作,可有效防止对胸腰椎脊髓及神经的损伤,适用于创伤外科、骨科与脊柱外科;同时还适合在野战、救灾等艰苦条件中使用.
