摘要

The surgical instrument is adapted to adjust the position of bone fragments of a limb. It has an outer ring with longitudinal connecting members and a smaller ring carrying clamps for needles fixed within the larger ring. A system of threaded studs enables the inner ring to move in any direction and turn within the outer ring. The inner ring can also be positioned in a plane turned by an angle with respect to the plane of the outer ring.
