Abstract

一种内螺纹结构式骨栓,它由带有外螺纹的子钉和带有内螺纹的母钉组成,在子钉的内部有纵向通孔,在母钉内部除内螺纹外亦有通孔,在子钉和母钉的端部有凸起,在子钉和母钉的端部有凹槽,凹槽呈一字形,或十字形,或正三角形,或正方形,或正五边形,或正六边形。本实用新型的有效效果是,应用本实用新型的内螺纹结构式骨栓,骨栓上紧后不会螺栓头过长,不存在压迫皮肤,因而不会造成慢性滑囊炎,没有疼痛,有利于功能恢复。

Description

内螺纹结构式骨栓
所属技术领域
本实用新型涉髁部骨折手术的医疗器具。
背景技术
在此以前,常规的用于股骨髁部及胫骨髁部骨折而固定的骨栓,是螺栓结构的骨栓,即用一只螺杆加一只螺母来固定。这种螺栓结构的骨栓存在不足之处,是骨栓上紧后螺栓头过长,压迫皮肤,造成慢性滑囊炎,有疼痛,影响功能恢复。
实用新型内容
本实用新型的目的是为了解决上述问题而提供一种内螺纹结构式骨栓,骨栓上紧后不会螺栓头过长,不存在压迫皮肤,因而不会造成慢性滑囊炎,没有疼痛,有利于功能恢复。
本实用新型解决其技术问题所采用的技术方案是:内螺纹结构式骨栓由带有外螺纹的子钉和带有内螺纹的母钉组成,在子钉的内部有纵向通孔,在母钉内部除内螺纹外亦有通孔,在子钉和母钉的端部有突起,在子钉和母钉的端部有凹槽,凹槽呈一字形,或十字形,或正三角形,或正方形,或正五边形,或正六边形。
本实用新型的有效效果是,应用本实用新型的内螺纹结构式骨栓,骨栓上紧后不会螺栓头过长,不存在压迫皮肤,因而不会造成慢性滑囊炎,没有疼痛,有利于功能恢复。
附图说明:
图为本实用新型的内螺纹结构式骨栓的结构示意图。图中1-子钉,2-通孔,3-母钉,4-突起,5-凹槽。
具体实施方法:内螺纹结构式骨栓由带有外螺纹的子钉(1)和带有内螺纹的母钉(3)组成,子钉外径为6毫米,母钉外径为8毫米。在子钉的内部有纵向通孔(2),通孔直径为2毫米。在母钉内部除内螺纹外亦有通孔,在子钉和母钉的端部有突起(4),突起呈圆锥形,在子钉和母钉的端部有凹槽(5),凹槽呈正三角形。

Claims (2)

1、一种内螺纹结构式骨栓,其特征在于它由带有外螺纹的子钉和带有内螺纹的母钉组成,在子钉的内部有纵向通孔,在子钉和母钉的端部有突起,在子钉和母钉的端部有凹槽。
2、根据权利要求1所述的内螺纹结构式骨栓,其特征在于凹槽呈一字形,或十字形,或正三角形,或正方形,或正五边形,或正六边形。
