一种医用斜面刃口刨削刀具
本技术涉及医疗器械领域,尤其涉及一种医用斜面刃口刨削刀具。
技术介绍
随着关节镜和内镜手术的广泛开展,刨削动力系统也迅速发展,不断更新。现代刨削动力系统是一款高性能通用的外科工具,具有吸引通畅、清洗方便、安装快捷和全防水设计等优点。刨削器实际上由两个叠在一起的套管组成,两个套管均有窗口,通过固定的外刀管和旋转的内芯在尖端的窗口起切削作用,并将组织吸入刀刃口,通过吸引器将碎屑吸出,以达到切削目的。其中,刨削刀头的种类繁多,如双侧刨刀、全径刨刀、全径带齿刨刀、圆头打磨器或圆桶型打磨器等。刨削刀头与刀管的同轴度对刨削刀具的使用有着十分重要的影响。而现有技术中,刨削器的刀头和刀管的同轴度较低,造成手术中排削性能低且不能精确的切除骨刺和软组织。
技术实现思路
本技术的目的在于提供一种医用斜面刃口刨削刀具,能够实现刀头与刀管采用装配加工提高同轴度,解决刀具的排屑问题,提高切除骨刺或软组织定位准确性和刨削效率。为实现上述目的,本技术提出了一种医用斜面刃口刨削刀具,包括刀具总成、刀鞘总成、卡套、密封圈、内刀管、外刀管、内刀头和外刀头,所述内刀管内置于所述外刀管里,所述刀具总成与所述内刀管相连,所述刀鞘总成与所述外刀管相连,所述卡套固定在所述刀鞘总成上,所述密封圈设在所述刀鞘总成上;所述内刀头的尾部外壁和外刀头的尾部外壁上均设有一台阶,所述内刀管的头部内壁和外刀管的头部内壁上均设有与所述台阶相对应的台阶控;所述内刀头和外刀头通过所述台阶和台阶控分别与所述内刀管和外刀管对接,且所述内刀头和外刀头分别与所述内刀管和外刀管焊接固定;所述内刀头的头部设有边缘为圆弧 ...
