Technical field
The invention belongs to operating theater instruments, especially relate to a kind of external fixation of fracture device.
Background technology
Femoral intertrochanteric is fractured, and need fix so that skeleton connects growth recovery it.Fixing operation in the past all adopts the internal fixation mode, and the internal fixation mode needs general anesthesia or lumbar vertebra half fiber crops, and operation wound is big, and is bigger with the postoperative misery in patient's art, is unfavorable for the patient health recovery.Afterwards, develop into the external fixation mode that adopts, but because fixing external fixator accurately a kind of doctor's of being convenient to operation also do not appear, in the skeletal shape more complicated of femoral intertrochanteric position at present.
Summary of the invention
For this reason, technical problem to be solved by this invention provides a kind of doctor's of being convenient to operation, and fixing intertrochanteric fracture of the femur external fixator accurately is to overcome the deficiency that prior art exists.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of intertrochanteric fracture of the femur external fixator is characterized in that: comprise top mounting subassembly and following fixation kit and be connected top mounting subassembly and following fixation kit between contiguous block;
Said top mounting subassembly comprises upper plate, builds first top board and second top board on upper plate; The junction has the first needle tray hole obliquely between said first top board and the upper plate; Accompany a pair of armature between said second top board and the base plate, said a pair of armature junction radially has the second needle tray hole;
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 the present invention, 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 intertrochanteric fracture of the femur external fixator of the present invention 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.

The specific embodiment
As depicted in figs. 1 and 2, intertrochanteric fracture of the femur external fixator of the present invention, 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).
Following fixation kit 200 comprises lower shoe 201 and builds the lower platen 202 on lower shoe 201; On lower platen 202 and lower shoe 201 junctions, have (same near two of level the 3rd parallel tilted slotted holes 403; This needle tray has two involutory semi-circular groove to constitute, and lays respectively at lower platen 202 and lower shoe 201).
Have vertically (illustrating vertical paper direction) card chute 105 in the lower end of upper plate 100, contiguous block 300 upper ends have the card slippery fellow 301 who is arranged in card chute 105, and contiguous block 300 can be along card chute 105 longitudinal sliding motions of upper plate 100 like this; The lower end of contiguous block 300 has circular rotation draw-in groove 302, and the upper end of lower shoe 200 has the circle rotation dop 203 that is arranged in circular rotation draw-in groove 302.Lower end sidepiece at the lower end of upper plate 101 sidepiece and contiguous block 300 all has locating hole and is arranged in locating hole dog screw 404.
In the present invention, realize that through bolt 500 first top board 102, second top board 103 were fixed with being connected of upper plate 101, lower platen 202 was fixed with being connected of lower shoe 201.
More than be exactly intertrochanteric fracture of the femur external fixator of the present invention, its mode of operation is following:
At first; External fixator 001 is placed on patient's fracture; Earlier squeeze into two draw points through two first needle trays 401, then through fixation kit 200 down with respect to the rotation of top mounting subassembly 100 and vertical misalignment by top mounting subassembly 100 and following fixation kit 200 adaptive skeletal structures, squeeze into two draw points through the 3rd needle tray 403 again; Make that fixation kit 200 is also fixed down; At last adjust the on position and the direction of last root draw point through armature 104, thereby finally realizing the accurately fixing, as shown in Figure 3 of intertrochanteric fracture of the femur.
Through above-mentioned detailed description, can find, the present invention have from outside accurately the resected femur intertrochanteric fracture, make things convenient for the doctor to operate, reduce patient's painful advantage of performing the operation.
