【技术实现步骤摘要】
一种简易下肢骨折牵引复位器
本技术属于医疗器械
,具体涉及一种结构简单、使用方便、成本低的简易下肢骨折牵引复位器。
技术介绍
股骨骨折是临床常见的一种类型,常常需要进行手术处理。而大腿部由于股四头肌、股二头肌、髂腰肌等肌肉的牵拉作用,产生了成角、短缩、旋转等移位,而且股骨骨折易发生大腿严重肿胀,需1-2周后才能手术,常需进行术前的下肢牵引,但术中仍易产生移位。所以术中仍然需要借助下肢牵引以进行复位并加以维持利于进行手术。目前术中最常见的牵引方法是使用手术牵引床上的下肢牵引架进行下肢牵引。其优点是能在进行下肢牵引的同时便于进行C臂X光机透视尤其是髋部,但须拆除臀部以远的手术床部分改用下肢牵引架,虽然下肢牵引架能进行牵引、旋转复位,但由于骨折断端失去手术床的支撑,在重力作用下就产生的向下成角,不利于更好的复位,尤其是粉碎性骨折。同时使用下肢牵引架需拆除原有部分手术床,再进行下肢牵引架安装,步骤繁琐且耗时。在许多基层医院购买下肢牵引床需数十万之巨,而普通手术床则便宜许多。因此设计一种既能防止骨折端向后下沉成角,又不影响C臂X光机透视,且操作简便又价廉的下肢手术牵引架显得尤为重要。
