Detailed Description

The technical solution of the present invention is explained in detail by the accompanying drawings and the specific embodiments.

As shown in fig. 1 to 2, the present invention provides a needle-type locking bone plate and nail system structure for distal radius fracture, comprising: the implant needle 1, the compression fixing needle 2, the bending part 3, the compression part 4, the compression plate 5, the locking screw 6 and the cortical screw 7; wherein implant the needle and be connected with the fixed needle of pressurization through the kink, add the splenium and be "U" type structure, its tail end is the arc shape, sets up the increased pressure board on two arms of adding the splenium, and the increased pressure board sets up the back taper fixed slot and pushes down two arms of adding the splenium simultaneously, sets up the screw hole on the increased pressure board, and locking screw and cortical screw pass from the screw hole, pressurize fixedly to the bone piece.

The implantation needle is inserted into a far-end bone block of a radius separated after fracture, the pressurizing fixing needle part limits a fixed end of the radius, the pressurizing plate is provided with screw holes, and the locking screw and the cortical screw respectively penetrate through the corresponding screw holes to pressurize and fix the bone block, so that the far end of the radius is pressurized through the pressurizing part, and the implantation needle 1, the pressurizing fixing needle 2, the bending part 3, the pressurizing part 4, the pressurizing plate 5, the locking screw 6 and the cortical screw 7 form a complete integral force application structure when in use, so that the far-end bone block of the radius is uniformly stressed and is not easy to fall off.
