External fixation system for realizing osteosynthesis between bone portions of radius after simple extra-articular fracture, has trigger guard positioning clamps relative to one another such that bottoms of clamps are located on same line

摘要

The system has an attaching unit for attaching proximal ends of an intrafocal pin (10) and a rectilinear pin (20). The unit includes a trigger guard (46) to fixedly connect U shaped clamps (41, 42). The guard maintains faces (341, 342) of the clamps at a distance equal to the diameter of the proximal end of one pin to define a receiving space (48) between the faces to receive the proximal end. The guard positions the clamps relative to one another such that bottoms of the clamps are located on a same line (100). The clamps and the guard are made of a single part.
