Said fixation kit down comprises lower shoe and builds the lower platen on lower shoe to have the 3rd tilted slotted hole on said lower platen and the lower shoe junction;
The lower end of said upper plate has vertical card chute, and it is foxy that said contiguous block upper end has the card that is arranged in said card chute; The lower end of said contiguous block has circular rotation draw-in groove, and the upper end of said lower shoe has the circle rotation dop that is arranged in said circular rotation draw-in groove; The lower end sidepiece of said upper plate and the lower end sidepiece of contiguous block all have locating hole and are arranged in the locating hole dog screw.
In the specific embodiment of this utility model, said second top board is positioned at the below of first top board.
The corresponding position that said a pair of armature is installed of said second top board and upper plate has the circular groove of ccontaining said a pair of armature.
In the specific embodiment, the said first needle tray hole has two, and the two laterally arranges; The two or three needle tray hole has two; The two laterally arranges.
Adopt technique scheme; When the intertrochanteric fracture of the femur external fixator of this utility model is used for the intertrochanteric fracture of the femur external fixation; Can carry out utilizing the rotation of a pair of armature to carry out the adjustment of draw point direction of insertion according to the skeleton concrete structure; And can make the adaptive patient's skeleton of external fixator through relative rotation between top mounting subassembly and the following fixation kit and vertical misalignment, so reach fixing accurately, be convenient to the advantage of doctor's operation.
Description of drawings
Be elaborated below in conjunction with accompanying drawing and specific embodiment this utility model:
Fig. 1 is the structural representation of this utility model;

The specific embodiment
As depicted in figs. 1 and 2, the intertrochanteric fracture of the femur external fixator of this utility model, comprise top mounting subassembly 100 and following fixation kit 200 and be connected top mounting subassembly 100 and following fixation kit 200 between contiguous block 300.
Wherein, top mounting subassembly comprises upper plate 101, first upper cover plate 102, second upper cover plate 103, a pair of armature 104.
Second upper cover plate 103 is positioned at the below of first upper cover plate 102; A pair of armature 104 is sandwiched between second upper cover plate 103 and the upper plate 101, and second upper cover plate 103 and the upper plate 101 corresponding positions that these a pair of armatures 104 are installed have the circular groove 106 of ccontaining a pair of armature 104.Like this, armature 104 can rotate in circular groove 105, and can not slide out.Radial position at a pair of armature 104 has second needle tray 402 (same, this needle tray has two involutory semi-circular groove to constitute, and lays respectively on two armatures 104).
