    • An intraosseous delivery apparatus having a drilling member and a sleeve member. The drilling member includes a drill housing, a connecting portion for establishing a connection to a conventional dental drilling apparatus, and a drill extending from the drill housing. The sleeve member includes a sleeve housing, and a hollow sleeve extending from the sleeve housing. The sleeve housing is adapted to be removably engaged with the drill housing such that the drill is inserted into the hollow sleeve. The drill has a length such that when the drill is inserted into the hollow sleeve, a portion of the drill extends beyond the hollow sleeve. As a result, when the drill is used to drill a hole in bone, the drill is inserted deeper into the hole than the hollow sleeve. The hollow sleeve is adapted to be left inserted in the bone when the drill is removed therefrom. The “in place” hollow sleeve is also adapted to receive a syringe needle through which anesthesia may be directly introduced into the bone via an exposed bottom portion of the drilled hole as well as via exposed side-wall portions of the drilled hole. The drill is preferably smooth, and may also be hollow so that debris generated during drilling enters the interior of the drill. In this case, when the hollow drill is removed from the hollow sleeve, the debris within the hollow drill may also be removed.
    • 具有钻孔构件和套筒构件的骨内输送装置。 钻孔构件包括钻子壳体,用于建立与常规牙科钻孔设备的连接的连接部分和从钻子壳体延伸的钻头。 套筒构件包括套筒壳体和从套筒壳体延伸的中空套筒。 套筒壳体适于与钻孔壳体可拆卸地接合,使得钻头插入中空套管中。 钻头具有这样的长度,使得当钻头插入中空套管时,钻头的一部分延伸超过中空套管。 结果,当钻头用于在骨头中钻孔时,钻头比中空套管更深地插入孔中。 当从其中移除钻头时,中空套筒适于被插入骨中。 “就位”中空套管还适于接收注射器针头,麻醉可以经由钻孔的暴露的底部部分以及经过暴露的钻孔的侧壁部分直接引入到骨骼中。 钻头优选是平滑的,并且也可以是中空的,使得在钻孔期间产生的碎屑进入钻头的内部。 在这种情况下,当中空钻头从中空套筒移除时,空心钻头内的碎屑也可以被移除。

    • 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.
    • 一次性直角牙科手柄包括一个一次性塑料外壳,其中有一个细长的开口,用于容纳优选由金属制成的驱动轴机构。 驱动轴机构通过快速连接快速断开机构连接到一次性外塑料外壳。 外壳还包括与驱动轴机构的端部处的齿轮接合的齿轮,工作构件连接到齿轮以由驱动轴构件驱动。 驱动轴构件可连接到牙科工具以由其驱动。

    • A lubricant delivery system for a dental handpiece, the dental handpiece having an air inlet tube having a predetermined internal shape in the vicinity of an open end portion thereof. The lubricant delivery system comprises a squeezable sealed capsule which includes a main body portion and a necked down portion extending from the main body portion. The necked down portion is smaller than the internal shape of the air inlet tube and is insertable into the open end of the air inlet tube. A passage is formed in the necked down portion extending from the main body portion to a tip end portion of the necked down portion. A lubricant fills at least a part of the squeezable main body portion. When the tip end portion of the necked down portion is opened, the opened necked down portion is inserted into the air inlet tube of the dental handpiece and the main body portion is squeezed to expel lubricant contained therein into the handpiece via the air inlet tube. The capsule may be sealed within a packaging material, and may be packaged with or without an opening member, such as a sterile needle or the like. The air inlet tube may be designed to have an opening member, such as a needle, built therein, for piercing the tip end portion of the necked down portion of the capsule.
    • 一种用于牙齿手柄的润滑剂输送系统,所述牙齿手柄具有在其开口端部附近具有预定内部形状的进气管。 润滑剂输送系统包括可挤压密封胶囊,其包括主体部分和从主体部分延伸的颈缩部分。 颈缩部分小于进气管的内部形状,并且可插入空气入口管的开口端。 在从主体部延伸到颈缩部的前端部的颈缩部形成有通道。 润滑剂填充可挤压主体部分的至少一部分。 当颈缩部分的前端部分打开时,开口的颈缩部分被插入到牙科手机的进气管中,并且挤压主体部分以通过进气管将其中容纳的润滑剂排出到手持件中。 胶囊可以密封在包装材料内,并且可以包装有或不带有诸如无菌针等的开口部件。 空气入口管可以设计成具有内置的打开构件,例如针,用于刺穿胶囊的缩颈部分的尖端部分。
