一种骨科用医用锯
本技术涉及医疗器械
,特别是涉及一种骨科用医用锯。
技术介绍
现有的医用骨锯大都结构简单、功能不全,医生使用时比较费力并且在锯的过程中容易左右错位,造成失误,影响手术的正常进行。
技术实现思路
本技术主要解决的技术问题是提供一种骨科用医用锯,能够防止左右错位。为解决上述技术问题,本技术采用的一个技术方案是:提供一种骨科用医用锯,包括左支座、左支撑臂、左连接杆,右支座、右支撑臂、右连接杆、纵向滑轨、锯片安装板和锯片,所述左支撑臂和右支撑臂均为L型,所述左支撑臂的竖臂固定连接左支座,所述右支撑臂的竖臂固定连接右支座,所述左支撑臂和右支撑臂的横臂均设有导槽,所述左连接杆插接在左支撑臂的导槽内,所述右连接杆插接在右支撑臂的导槽内,所述左支撑臂和右支撑臂的横臂上均设有用于固定左连接杆和右连接杆的调节螺母,所述纵向滑轨的两侧分别固定连接左连接杆和右连接杆,所述纵向滑轨设有滑槽,所述纵向滑轨的下端面设有连通滑槽的限位孔,所述锯片安装板滑动连接在滑槽内,且锯片安装板至少部分伸出限位孔,所述锯片安装板的上端设有用于防止脱出限位孔的限位板,所述限位板与纵向滑轨之间连接有拉簧,所述锯片安装在锯片安装板的下端面,所述锯片安装板的两侧分别安装有握柄,所述握柄表面设有防滑橡胶垫。本技术的有益效果是:区别于现有技术的情况,本技术的左连接杆与左支撑臂、右连接杆与右支撑臂通过相对移动来确定纵向滑轨的位置,纵向滑轨设有滑槽,锯片安装板与滑槽滑动连接,且通过拉簧连接纵向滑轨,锯片安装板受到纵向滑轨的限位孔的限制无法左右移动,只能克服拉簧的拉力做上下移动,从而能够防止左右错位,医 ...
