    • A surgical tool for inserting a dental implant into a maxillary or mandibular socket. The tool comprises an elongated housing having a proximal end and a distal end and a drive shaft disposed therein. The distal end has a head enclosing a gear and pinion, the pinion being driven by the drive shaft. The pinion drives the gear so that the rotation of the gear is perpendicular to or approximately perpendicular to the rotational direction of the pinion. The gear is adapted to receive a screw carrying system or an adaptor which is adapted to receive a screw carrying system. A handle affixed to the drive shaft is disposed at and adjacent to the proximal end of the housing. When the implant is engaged with the screw carrying system, the handle is rotated to screw the implant into the socket and secure it to the bone. The tool of the invention also can be used to remove an implant.
    • 用于将牙科植入物插入上颌骨或下颌骨窝的手术工具。 该工具包括具有近端和远端以及设置在其中的驱动轴的细长壳体。 远端具有包围齿轮和小齿轮的头部,小齿轮由驱动轴驱动。 小齿轮驱动齿轮,使得齿轮的旋转垂直于或近似垂直于小齿轮的旋转方向。 该齿轮适于接收螺旋传送系统或适于接收螺旋传送系统的适配器。 固定到驱动轴的手柄设置在壳体的近端处并邻近壳体的近端。 当植入物与螺钉承载系统接合时,旋转手柄以将植入物旋入套筒并将其固定到骨头上。 本发明的工具也可用于移除植入物。
