Abstract

本实用新型属于医疗用品,公开了一种新型骨钉,其包括钉杆和钉帽,钉杆外侧壁设有螺纹,钉帽呈长方体,其上端面设有注入孔;钉杆侧壁对称设有两条纵向的凹槽,所述的凹槽上端与注入孔相通。钉帽采用长方体,棱角不易损坏,取出骨钉时容易夹持;骨钉取出时,可通过注入孔向凹槽内注入润滑剂,减少骨钉与骨质的摩擦,降低骨钉取出难度。

Description

一种新型骨钉
技术领域
本实用新型涉及一种医疗用品,尤其涉及一种新型骨钉。
背景技术
钢板内固定是治疗骨折的常用方法,其是通过骨钉将钢板固定于骨折部位,对断骨起到固定、限位的作用。由于断骨愈合后,需要将钢板取出,而骨钉与新发育的骨质结合往往较为紧密,取出难度较大,如操作不当很容易将骨钉折断,还需在骨质上凿孔才能取出,操作较为麻烦。
实用新型内容
为克服上述技术问题,本实用新型提供了一种结构设计合理,固定效果好,且愈合后容易取出的新型骨钉。
为实现上述技术目的,本实用新型采用以下方案:一种新型骨钉,包括钉杆和钉帽,钉杆外侧壁设有螺纹,其特征在于:钉帽呈长方体,其上端面设有注入孔;钉杆侧壁对称设有两条纵向的凹槽,所述的凹槽上端与注入孔相通。
本实用新型具有以下有益效果:钉帽采用长方体,棱角不易损坏,取出骨钉时容易夹持;骨钉取出时,可通过注入孔向凹槽内注入润滑剂,减少骨钉与骨质的摩擦,降低骨钉取出难度。其结构简单,固定效果好,且容易取出,具有显著的实用性。
附图说明
图1为本实用新型结构示意图。
图中,1、钉杆,2、螺纹,3、钉帽,4、注入孔,5、凹槽。
具体实施方式
参看附图所示,一种新型骨钉,包括钉杆1和钉帽3,钉杆1外侧壁设有螺纹2,其特征在于:钉帽3呈长方体,其上端面设有注入孔4;钉杆1侧壁对称设有两条纵向的凹槽5,所述的凹槽5上端与注入孔4相通。
