An apparatus for handling of an implant for a body is described. The apparatus includes a head with a radio-translucent first window insert. The apparatus also includes an arm that is telescopically extendible along a first axis. The head is rotatable around the first axis and axially moveable along the first axis. A radio-opaque pattern is on each face of the window insert. The two patterns complement one another to occlude radiation only when the angle of the radiation striking each window is precisely perpendicular to the plane of the window. An apparatus having a radio-translucent arm with an array of parallel radio-opaque markings is also described. The apparatus comprises an arm and a head, having a clamp for a drill guide/K-wire. The clamp, the arm and the array of radio-opaque markings are mutually parallel. The clamp defines an axis of insertion for the drill guide/K-wire, the axis being spaced from the plane of the array. |
