医用切割圆规刀
本技术涉及医疗用具,具体地说是一种医用切割圆规刀。
技术介绍
临床上,对于需要电切除的膀胱癌患者,通常中腹壁黏贴尿袋,将腹内人造尿管与贴在腹壁上的尿袋相连通,但对于尿袋的固定,通常采用胶片固定,为了与腹内的人造尿管紧密贴合,通常需要将胶片剪切一个圆孔,圆孔的直径与人造尿管的直径相同,而护士在剪切过程中,为了能使圆孔与人造尿管相吻合,需要多次剪切,剪切出的圆孔时大时小,导致操作繁琐、使用不方便、工作效率低小,同时,当圆孔大于人造尿管直径时,会使人造尿管与腹壁之间产生间隙,进而无法保证人造尿管在腹壁的定位。
技术实现思路
本技术的目的是解决上述现有技术的不足,提供一种结构新颖、操作方便、圆切割精确、工作效率高、人造尿管定位稳定的医用切割圆规刀。本技术解决其技术问题所采用的技术方案是:一种医用切割圆规刀,其特征在于设有主支杆、副支杆、定位针、把柄、刻度板、轴套、铰轴、刀片安装架、定位套箍和刀片,所述主支杆和副支杆上端经铰轴连接,所述主支杆下端设有定位针,所述主支杆下部活动套接有轴套,所述铰轴上端固定有把柄,所述副支杆下端铰接有刀片安装架,所述刀片安装架下端插接有刀片,所述刀片经螺钉固定,所述刀片安装架上活动套接有定位套箍,所述轴套一侧与刻度板相铰接,以使刻度板在不使用时,可以与主支杆相折叠,所述刻度板上设有刻度线,所述刻度板一侧对应刻度线设有刀片定位凹槽,以利于通过刀片定位凹槽定位刀片,避免刀片在旋切过程中改变方向,所述定位套箍呈倒U形,当所述刀片插在刀片定位凹槽中时,刀片安装架经定位套箍与刻度板相插接固定,当旋切完毕,将定位套箍上移,并同时旋转刻度 ...
