    • An instrument system is provided for positioning an internal fixation prosthesis and guiding a cannulated bone drill during a surgical, radioscopic procedure for the repair of a fractured bone of a patient. The instrument system includes a target wire, a handle formed from a radio translucent material having a target hole for guided passage of the target wire along a target axis. The target axis coincides with the intersection of a first plane and a second plane orthogonal to the first plane. The instrument system also includes a nose component attached to an end of the handle and removably connectable to the prosthesis. The nose component includes an alignment sight formed from a radio-opaque material. When the prosthesis is connected to the nose component and the target wire is positioned through the target hole along the target axis, the image of the guide wire may be radioscopically viewed along a first line of sight contained in the first plane to bisect the image of the alignment device, thereby providing a first visual reference to the user for directing the first guide wire into the desired portion of the bone while holding the prosthesis in a desired position relative to the bone.
    • 提供了一种用于定位内固定假体并在用于修复患者骨折骨的外科手术放射学程序中引导插管骨钻的仪器系统。 仪器系统包括目标线,由无线电半透明材料形成的手柄,其具有用于目标线沿目标轴引导通过的目标孔。 目标轴与第一平面和与第一平面正交的第二平面的交点重合。 仪器系统还包括附接到手柄的端部并可拆卸地连接到假体的鼻部部件。 鼻部组件包括由不透射线材料形成的对准视线。 当假体连接到鼻部部件并且目标线沿着目标轴线定位穿过目标孔时,可以沿着包含在第一平面中的第一视线来放射线地观察导丝的图像,以将图像平均化 对准装置,从而为使用者提供第一视觉参考,用于将第一导丝引导到骨骼的期望部分中,同时将假体保持在相对于骨骼的期望位置。

    • An instrument system is provided for positioning an internal fixation prosthesis and guiding a cannulated bone drill during a surgical, radioscopic procedure for the repair of a fractured bone of a patient. The instrument system includes a target wire (180), a handle (106) formed from a radio translucent material having a target hole for guided passage of the target wire along a target axis. The target axis coincides with the intersection of a first plane and a second plane orthogonal to the first plane. The instrument system also includes a nose component (150) attached to an end of the handle and removably connectable to the prosthesis.
