Abstract

一种钢板孔扩大钻头,它由金属材料制成,不同之处在于钻体(3)的上端固定连接电钻连接头(2),其下端连接钻头(1),因而,结构简单、设计合理、使用方便快捷、可以避免手术中骨质大量破坏、又易取出病人内固定钢板螺钉,特别适合于骨科手术钢板扩孔之用。

Description

钢板孔扩大钻头
技术领域:
本实用新型涉及一种医疗手术器械,特别是一种骨科手术用的钢板孔扩大钻头。
背景技术:
目前,在我国骨科手术后病人体内存有内固定钢板,由于国内固定钢板螺钉在制造时各厂家选择材料类型不同,或者钢板内固定时间过长等原因,造成手术后病人内固定钢板螺钉很难取出,即使在手术中强行取出螺钉也能造成骨质大量破坏,已发生再次骨折,现在,我国还没有一种器械能很好的取出螺钉。
发明内容:
本实用新型就是要提供一种结构简单、设计合理、使用方便快捷、可以避免手术中骨质大量破坏、又易取出病人内固定钢板螺钉的钢板孔扩大钻头。
本实用新型的目的是这样实现的:一种钢板孔扩大钻头,由金属材料制成,其特征在于钻体的上端固定连接电钻连接头,其下端连接钻头。
所述的钻头为空心钻头。
所述的钻头、电钻连接头和钻体都为圆柱体状。
本实用新型与现有技术相比具有以下优点:
由于采用了钻体的上端固定连接电钻连接头,其下端连接钻头的结构形式,因而,结构简单、设计合理;只需将电钻连接头与电钻连接即可使用,因而,操作简单、缩短了手术时间、减轻了劳动强度、避免手术中骨质大量破坏,又易取出病人内固定钢板螺钉
附图说明:
图:为本实用新型具体结构示意图
1、钻头    2、电钻连接头    3、钻体
具体实施方式:
钻头1、电钻连接头2和钻体3都采用金属材料制成,为圆柱体状,钻头1为空心钻头,其上端固定连接钻体3,钻体3的上端固定连接电钻连接头2。
使用时,当手术中显露钢板后,将电钻连接头2与电钻连接固定住,电钻接通电源,再将钻头1顶入钢板孔后,即可开始扩孔。

Claims (3)

1.一种钢板孔扩大钻头,由金属材料制成,其特征在于钻体(3)的上端固定连接电钻连接头(2),其下端连接钻头(1)。
2.根据权利要求1所述的钢板孔扩大钻头,其特征在于所述的钻头(1)为空心钻头。
3.根据权利要求1或2所述的钢板孔扩大钻头,其特征在于所述的钻头(1)、电钻连接头(2)和钻体(3)都为圆柱体状。
