| 摘要 | A targeting device for targeting a cross bore in a bone nail has an arm member coupled to an end portion of the bone nail and an aiming portion forming part of the arm member extending parallel to a longitudinal axis of the bone nail. An adjustable aiming device is mounted on the aiming portion, the adjustable device having a guide bore alignable with the cross bore in the nail. The adjustable device is moveable with respect to the aiming portion in a direction perpendicular to a plane containing both the nail longitudinal axis and central axis of the cross bore. A target indicator is mounted on the adjustable aiming device. The target indicator has a radiolucent body including a planar portion having spaced parallel radiopaque elements therein. | ||

| 主权项 | 1. A targeting device for targeting a cross bore in a bone nail using an x-ray beam comprising: an arm member capable of being coupled to an end portion of a bone nail, wherein the arm member comprises an aiming portion extending along a first axis parallel to a longitudinal axis of the bone nail; an adjustable aiming device mounted on the aiming portion, the adjustable aiming device having a guide bore alignable with the cross bore in the nail, the adjustable aiming device moveable with respect to the aiming portion in a direction perpendicular to a first plane containing both the nail longitudinal axis and a central axis of the cross bore; and a target indicator mounted on the adjustable aiming device, the target indicator having a radiolucent body including first and second angled legs forming an apex at a first end of each leg, the first leg extending along a second axis and having spaced elongate radiopaque elements therein, the second leg having an alignment pin, the first leg radiopaque elements extending in a plane perpendicular to the first plane and the second leg portion alignment pin extending along a third axis which is angled at an angle of between 15° and 60° with respect to the second axis, the third axis alignable with the x-ray beam. | ||
