对截石位手术床腿架装置的改进与制作

Modification and manufacture of leg trestles of operating table for lithotomy position

目的针对目前手术室使用的截石位手术床腿架存在调节费力、螺丝松脱会造成病人大腿受伤的问题,笔者设计了一种可以通过前后移动来调整高度的截石位手术床腿架。方法手术床腿架主干采用不锈钢材质制作,由主撑、滑套、斜撑、撑杆和腿托5个部分组成,主撑和斜撑分别固定于手术床床尾同一侧的上下选定部位,滑套套装在主撑上,与斜撑相连;斜撑为气弹簧组件,其长度可调,用来调节腿架的高度,腿托通过可以左右两个自由度活动的撑杆固定在滑套上。结果它操作方便,升降平缓安全,解决了操作费力及存在安全隐患的问题。结论较之原先未改进的手术床腿架,缩短了手术摆位时间,更易于调整双腿分开角度,提高了腿位放置的舒适度,医生、护士使用操作更加灵活、方便、可靠。
