    • An intraosseous delivery apparatus having a drill coupling member and a drilling needle member. The drill coupling member includes a shaft, an open housing provided at one end of the shaft, a connecting portion provided at an opposite end of the shaft for establishing a connection to a conventional dental drill, and an anticlog needle extending from the shaft through the open housing. The drilling needle member includes a drilling needle housing and a hollow drilling needle shaft extending therefrom. The drilling needle member is adapted to be removably engaged with the drill coupling member such that the drilling needle housing of the drilling needle member is inserted into the open housing of the drill coupling member and such that the anticlog needle of the drill coupling member is inserted into the hollow drilling needle shaft of the drilling needle member. The drilling needle housing of the drilling needle member and the open housing of the drill coupling member are shaped so that a bone penetration force may be applied therebetween for drilling a hole in a bone to insert the drilling needle member therein when the drilling needle member and the drill coupling member are engaged. The hollow drilling needle shaft is adapted to receive a needle of a syringe when the drilling needle member and the drill coupling member are disengaged and the drilling needle member is left inserted in the hole drilled in the bone, so that a reusable communication path through the hollow drilling needle shaft directly into the hole drilled in the bone is established through which fluid may be repeatedly injected.
    • 具有钻耦合构件和钻针构件的骨内输送装置。 所述钻头联接构件包括轴,设置在所述轴的一端处的敞开壳体,设置在所述轴的相对端处的连接部分,用于建立与常规牙钻的连接,以及从所述轴延伸穿过所述轴 开放的房屋。 钻针构件包括钻孔壳体和从其延伸的中空钻头针轴。 钻孔构件适于可拆卸地与钻头联接构件接合,使得钻孔针构件的钻孔壳体插入到钻头联接构件的敞开的壳体中,并且使得钻头联接构件的防结扎针插入 进入钻孔针孔的中空钻针轴。 钻针构件的钻孔壳体和钻头联接构件的打开壳体的形状使得可以在其间施加骨穿透力以在骨头中钻孔以在钻孔针构件和 钻接头构件接合。 当钻孔针元件和钻头联接元件脱离并且钻孔针元件被插入在钻孔中的孔中时,中空的钻孔针适于接收注射器的针,从而通过 空心钻针轴直接插入到钻孔中的孔中,通过该孔可以反复注入流体。

    • A disposable right angle dental handpiece comprises a disposable plastic outer housing having an elongated opening therein for receiving a drive shaft mechanism which is preferably made of metal. The drive shaft mechanism is connected to the disposable outer plastic housing by means of a quick connect-quick disconnect mechanism. The outer housing also contains a gear which is engaged with a gear at the end of the drive shaft mechanism, a working member being connected to the gear for being driven by the drive shaft member. The drive shaft member is connectable to the dental tool for being driven thereby. Also disclosed are embodiments wherein the drive shaft mechanism is connected to the dental drive tool, and wherein the outer housing is independently connected to the dental drive tool by means of a quick connect-quick disconnect mechanism, which locks the outer housing relative to the dental drive tool in both the longitudinal and circumferential directions.
