Patent ID: 8287548

Claim:
A wire fixation device for fixing a wire or a pin to a medical device comprising a wire or a pin, a wire post having a head portion with an opening having a predetermined longitudinal axis for reception of said wire and a neck portion for being in engagement with an opening of the medical device, a locking element that is introduced into the opening having an opening with inclined sections that are inclined to the longitudinal axis, an abutment element, and a clamping cone having a clamping opening in which said wire or said pin is arranged and inclined outer surfaces that are inclined to the longitudinal axis, wherein said clamping cone abuting on said abutment element and wherein said clamping cone is received at least partly in said opening of said locking element thereby said inclined surfaces of the clamping cone are in engagement with the inclined sections of the locking element such that upon an axial displacement of the locking element relative to the clamping cone a radial force is exerted onto the clamping cone leading to a reduction of the diameter of the clamping opening such that a radial force results onto said wire or said pin which is inserted into the clamping opening wherein the neck portion is elongated and substantially cylindrical and comprises a slot extending through the neck portion from an end face being opposite the head portion to the opening of the head portion and in that the locking element and the clamping cone each comprise a slot extending along axial direction over the whole length of the respective sidewall and along radial direction from the respective circumferential surface into the respective reception or clamping opening and wherein the locking element and the clamping cone are arranged such with respect to each other and to the wire post that a through slot is being provided in order to introduce the wire via the slot in the wire post, via the slot in the locking element and via the slot in the clamping cone into the clamping opening in a direction transverse to the longitudinal axis.
