一种带刻度标识医用刨削刀具
本技术涉及医疗器械领域,尤其涉及一种带刻度标识医用刨削刀具。
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。刨削刀具进入人体各关节腔进行软组织或骨刺切除操作,通过关节镜观察,难以把握刨削刀具的刨削方向和工作距离,易造成切除不完全,无法到达手术预期效果,或切除过度,对患者造成伤害等影响。
技术实现思路
本技术的目的是为了提供一种带刻度标识医用刨削刀具,精确判断刀具的朝向及工作距离,避免切除多余组织。为了实现上述目的,本技术提出一种带刻度标识医用刨削刀具,包括内刀、外刀、套环和卡圈,所述内刀置于所述外刀内部;所述内刀包括依次相连的内刀头、内刀管和内刀柄;所述内刀头、内刀管和内刀柄内设有轴向贯通的空腔,所述内刀柄的外侧设有与内部空腔贯通的吸引窗;所述外刀包括依次相 ...
