Description

牙根桩钉打孔器
一、技术领域
本实用新型属于医疗用具技术领域,具体地讲是一种新型牙根桩钉打孔器。 
二、背景技术 
临床口腔科医师在给患者进行镶补牙时,大多需要使用桩钉,目前的桩钉由桩钉头和螺纹钉体构成,使用时用牙科粘结材料将螺纹钉体粘接在牙根管中,再用粘结材料把烤瓷冠体、树脂或假牙粘接在桩钉头上,由于螺纹钉体的螺纹细小,螺纹钉体粘接在牙根管中时,粘接不牢固,容易脱落,由于桩钉头比较光滑,粘接在假牙上也容易松动,给病人带来了痛苦。 
三、发明内容:
本实用新型的目的是提供一种牙根桩钉打孔器。 
本实用新型的目的是通过如下技术方案来完成的,一种牙根桩钉打孔器,由打孔器主体(1)、冲杆(2)、弹簧(3)、锥形头(4)、卡子(5)和加力杆(6)构成,其特征在于锥形头(4)一头安装在打孔器主体(1)的冲杆(2)上,其上设有带弹簧(3)的卡子(5)。 
所述的锥形头(4)一头呈锥形状,一头带丝扣。 
所述的打孔器主体(1)的冲杆(2)呈螺纹状,上端有加力杆(6),下端由内丝扣,连接锥形头(4),其中所述的冲杆(2)上设有穿透孔。 
本实用新型与现有技术相比,具有结构简单,使用方便,安全卫生等特点。 
四、附图说明:
附图1是本实用新型的结构示意图。 
其中:1、打孔器主体 2、冲杆 3、弹簧 4、锥形头 5、卡子 6、加力杆 
五、具体实施方式
下面将通过附图对本实用新型作详细的介绍:牙根桩钉打孔器,由打孔器主体1、冲杆2、弹簧3、锥形头4、卡子5和加力杆6构成,其特征在于锥形头4一头安装在打孔器主体1的冲杆2上,其上设有带弹簧3的卡子5,通过冲杆2将锥形头4钻入牙根管内。 
所述的锥形头4一头呈锥形状,一头带丝扣。 
所述的打孔器主体1的冲杆2呈螺纹状,上端有加力杆6,下端由内丝扣,连接锥形头4,其中所述的锥形头4上设有穿透孔。 
使用时,用带弹簧3的卡子5卡在牙龈处,固定后,通过加力杆6带动呈螺纹状的冲杆2带着锥形头4钻入牙根孔里,松开加力杆6,旋出冲杆2,解开卡子5,将打孔器主体1取出后,再用空心钉体与锥形头4相接,牙科材料通过空心钉体进入锥形头4的穿透孔,使得与牙根管粘接更加牢固。
