一种神经触激术针刀
本技术涉及医疗器械
,具体是一种神经触激术针刀。
技术介绍
在治疗神经卡压时,常使用针刀进行切割皮肤、筋膜、分离肌肉,到达神经进行触激缓解卡压,解除疼痛。普通针刀具备切割功能,但触激神经时,容易损伤神经。利用钝头剥棒触激神经,虽然不会损伤神经,但必须先使用刀子切开皮肤、筋膜后才能使用,且更换工具费力费时。将针刀和剥棒结合在一起,发挥各自的优势,治疗过程一次完成。
技术实现思路
本技术旨在解决上述所提到的问题,本技术提供了一种神经触激术针刀,该神经触激术针刀操作安全,使用方便,便于存放。本技术的技术方案:一种神经触激术针刀,主要由空心剥棒、带刃内刀、内刀基座和复位簧组成。其中,空心剥棒兼做带刃内刀的外壳套筒,空心剥棒由医用合金做成,前端设有圆形钝头,钝头中心设有内刀出口,空心剥棒内腔前部设有环形凸起,空心剥棒后部设有螺帽。螺帽可以拧下,用于带刃内刀以及内刀基座的取放;空心剥棒后部的侧壁上开有“L”形通透窗。内刀基座为圆柱形,直径小于空心剥棒内腔的内径,为医用硬质塑料制成,内刀基座的前部侧壁上设有方形凸起,内刀基座朝前端的中心部位设有内刀插口;带刃内刀为一小型手术刀,刀片狭窄,前端有锋利的刀头,刀片的前半部设有“一”字形横挡,复位簧套装在带刃内刀上,组装在环形凸起与“一”字形横挡之间。组装使用时,拧下空心剥棒后部螺帽,将带刃内刀尾部插在内刀基座的内刀插口内,将复位簧套装在带刃内刀前部,位于“一”字形横挡的前部,将带刃内刀及基座装入空心剥棒的内腔,使内刀基座的方形突 ...
