Bone plate

A plate, plate covered with a top surface (1), one for the contact surface at the end of the bone (2) and a set of holes (4) covers the hole (4) is in the longitudinal axis of the plate as described in (3) above and connect the end of the top surface and the surface (1;2) so you can get bone screw (11). By in hole (4) in the of at least a including a combination, by in combination including a diameter for d symmetric Center for (SK) of round hole (14) and a symmetric Center for SL of long hole (24), by in long hole has a in by in plate of longitudinal axis party up extends of long axis-a and a with vertical of short axis b, symmetric Center (SK and SL) Zhijian of distance (-a) is less than d/2+a/2, and two a symmetric Center are is located in by in plate of longitudinal axis (3) is located of regional Shang. Invented by plate can not compromise as a Board and as a so-called internal fixator used.
