【技术实现步骤摘要】
一种克氏针折弯器
本技术属于医疗器械
,具体地说,本技术涉及一种克氏针折弯器。
技术介绍
在骨折手术治疗中,经常应用克氏针固定骨折部位,在骨头复位拼接好,然后用克氏针固定结束后需将克氏针针尾折弯,防止克氏针移位。传统的方法为两人协作法,一人用尖嘴钳夹紧,另一个进行折弯,二人必须同时用力,且用力方向相反,形成力偶,才可顺利折弯克氏针针尾。有时需多次进行,易造成克氏针金属疲劳和骨折移位,影响手术效果并存在隐患。特别是关节周围的骨折,更需精确、稳定的复位及固定,因此克氏针折弯尤为重要。同时其他折弯器体积较大,难以在小关节附近置入操作,影响使用范围。
技术实现思路
本技术提供一种克氏针折弯器,目的是实现克氏针在手术过程中的折弯操作。为了实现上述目的,本技术采取的技术方案为:一种克氏针折弯器,包括支架杆、操作杆和卡杆,所述支架杆前端焊接有套筒杆,且套筒杆内设有内螺纹,所述套筒杆一端焊接有驱动杆套,所述操作杆设于驱动杆套内部,所述卡杆与套筒杆连接,所述支架杆后端设有上把手,所述支架杆侧边设有滑槽,所述支架杆正下方设有下架,所述下架的一端与支架杆连接,另外一端与上把手连接。优选的,所述上把手和下架之间设有下把手,所述下把手一端设有齿条,另外一端设有滑块,所述齿条下端和滑块下端都设有挂耳,所述挂耳通过弹簧与下架连接。优选的,所述操作杆一端设有齿轮,且所述齿轮与齿条啮合,所述操作杆的另外一端设有折弯头。优选的,所述折弯头中分别设有第一折弯孔、第二折弯孔和第三折弯孔,且所述第一折弯孔的直径尺寸为2mm,第二折弯孔的直径尺寸为1mm,第三折弯孔的直径尺寸为0.5mm。优选的, ...
