ABSTRACT:
A device for installation of a guide wire for a drilling tool in a correct positional arrangement in a bone. The device includes a tissue protection sleeve, which has at one end a laterally projecting grip or handle. A trocar is provided, which trocar can be introduced into the tissue protection sleeve from the handle end and whose other end is closed. The trocar is rotatable in the tissue protection sleeve and has a central bore hole and a plurality of eccentric axially parallel bore holes, through which a guide wire can be passed. A second handle is provided which extends approximately in the same direction of the first handle and whose one end engages the end of the trocar situated the outside of the tissue protection sleeve, so that the normally freely rotatable trocar is fixed in the direction of rotation relative to the tissue protection sleeve, when both handles are manually clamped against each other.
