Description

一种残根拔除器
技术领域
本发明涉及医疗器械领域,具体地说是一种残根拔除器。
背景技术
残根多因拔牙时牙根折断或龋坏所致,因残根位置较深,在拔除时困难较大,常需采取扩大拔牙创、凿除一侧牙槽骨等方法来实现拔除的目的,上颌后牙的残根在拔除时还有被捅入上颌窦的危险,这不仅增加了手术创伤,而且也会引起诸多的医患纠纷。
发明内容
本发明提供了一种结构简单、设计新颖、操作方便的残根拔除器。
本发明是这样实现的:装置上部为手柄,手柄下设置有螺旋帽,底端为螺纹尖端,螺纹尖端上设置有螺纹,螺纹通过置入孔固定在基座上。
发明的有益效果是:该装置结构简单、设计科学并且容易操作,可最大限度地减少创伤,减轻了病人的痛苦和医务人员的劳动强度。
附图说明
下面结合附图作进一步说明。
图1是本发明的结构示意图。
图中:1、螺纹尖端,2、螺纹,3、置入孔,4、基座,5、螺旋帽,6、手柄。
具体实施方式
如图所示,装置上部为手柄6,手柄6下设置有螺旋帽5,底端为螺纹尖端1,螺纹尖端1上设置有螺纹2,螺纹2通过置入孔3固定在基座4上。
使用时,将螺纹尖端1旋入残根根管内,螺纹2通过置入孔3固定在基座4上,基座4放在相邻前后牙齿咬合面上,也可直接放在牙槽骨上,旋转螺旋帽5,平稳加力,即可使拔除器逐渐上移,同时可将残根拔出。
