<p>This invention is related to external skeletal fixator, which makes it possible for the conventional pins to be invested without any special guidance, with the possibility for the pins (4) to have three degreed movement, whereas the mere construction ensures the equalized three-dimensional stability, whereby the complex of the fixator is highly adjustable, suitable for the compression and distraction, as well as easy for the production and clinical application. According to this invention it is necessary to invest at least two pins (40) in each of the bone fragments. The essence of the invention lies in the construction of the carrier complex (2) of the clamp and the clamp (3). There are as many complexes as there are pins (40). The construction enables a sliding movement and rotational movement of the clamp (3) around the body (8) of the carrier (20), and the same possibility is granted to the carriers (2) that are pulled over the connective bar (1) by their circular holes on the cylindrical carrying head (9). Likewise, by the help of the gutters (44), the clamps are pulled overt the pins (40) invested in various different positions. What is achieved by the mutual adjustment of all elements and by the tightening of the screw (12) with the press-stud (13) is the fastening of the carrier (2) to the bar (1), and the clamp (3) for the carrier (2) and the pin (4) is fastened by the screw (47), which makes it possible for the fixation of both bone fragments to come into being.</p> |
