    • An intraosseous needle (10;70) having a threaded shaft (12;72) with a passageway (31;74) extending substantially therethrough, a solid and pointed tip (13;80) at one end thereof, the tip having a plurality of cutting edges (77,78,79) which facilitate boring through a bone. The shaft also includes two side ports (33,34;75,76) in communication with the passageway to allow fluids to pass through the needle into the interior of the bone after successful insertion thereof. There is a hub (11) at the opposite end of the shaft, whereby the needle is adapted to couple with an appropriate gripping device. A handle (50) is provided in the shape of a ball knob and is adapted to telescopically and grippingly receive the hub (11) of the needle. The hub and handle are both equipped with mutually engaging torque-transmitting surfaces.
    • 具有螺纹轴(12; 72)的骨内针(10; 70),所述螺纹轴具有基本上穿过其延伸的通道(31; 74),其一端处具有实心尖尖(13; 80),所述尖端具有多个 切割边缘(77,78,79),其有利于穿过骨头。 轴还包括与通道连通的两个侧端口(33,34; 75,76),以允许流体在其成功插入之后通过针进入骨的内部。 在轴的相对端具有轮毂(11),由此针适于与适当的夹紧装置联接。 手柄(50)设置成球形旋钮的形状,并且适于伸缩地并且夹紧地容纳针的轮毂(11)。 轮毂和手柄都配有相互接合的扭矩传递表面。
