    摘要： A drill for a medical needle having a fitting end and a tip suitable for intra-osseous use includes a chuck extending outwardly from a hand-held housing, the chuck including means for releasably receiving the needle at it fitting end. Energy storage means disposed within the housing couple rotational energy to the chuck and attached needle upon activation of a housing-supported switch. Energy storage may either be electrical, in which case the housing includes therein a battery and motor mechanically coupled to the chuck, and an electrical switch having operative connections to the motor and battery. The battery is preferably rechargeable and an optional inductive pick-up may be disposed within the housing along with power-conversion circuitry enabling the battery to be inductively charged. In an alternative embodiment the drill includes mechanical energy storage means in the form of a wind-up spring mechanically coupled to the chuck, and wherein the switch allows energy stored in the spring to be released to rotate the chuck and needle attached thereto.

    摘要翻译： 用于具有装配端和适于骨内使用的尖端的医用针的钻头包括从手持壳体向外延伸的卡盘，卡盘包括用于在其配合端可释放地接收针的装置。 设置在壳体内的能量存储装置在启动壳体支撑的开关时将旋转能量耦合到卡盘和附接的针。 能量储存可以是电气的，在这种情况下，壳体中包括机械耦合到卡盘的电池和马达，以及具有到马达和电池的操作连接的电开关。 电池优选地是可再充电的，并且可选的电感拾取器可以与功率转换电路一起设置在壳体内，使得电池能够感应充电。 在替代实施例中，钻具包括机械联接到卡盘的卷绕弹簧形式的机械能量存储装置，并且其中开关允许存储在弹簧中的能量被释放以使附接到其上的卡盘和针旋转。
