ABSTRACT:
The targeting device of this invention includes a radio-transparent handle and a metal snap fit barrel. The radio-transparent handle reduces obstructions in the radio-graphic image to provide a clearer image to the surgeon for proper placement of the locking screws. The metal snap fit barrel is retained in the handle by an interference fit between the handle and biased keys carried by the barrel. After use, the barrel may be easily disassembled for cleaning by striking a removal tool against the keys to drive the barrel from the handle.
