The beneficial effects of the utility model are: this utility model coordinates two screw rods by hinge, can realize the variation of angle, movement and rotation by two pin clip assemblies on threaded rod, can realize relative to prolongation, cripetura and rotate, finally reach the location of different directions length and angle, easy to adjust, can be with the last setting tool that operates, also can be with the instrument of the middle reset that operates.Meanwhile, this utility model is simple in structure, has high practical value.
Brief description of the drawings
Fig. 1 is the structure chart of Orthopaedic external fixator of the present utility model;
Fig. 2 is the structure chart of hinge block in this utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1, Orthopaedic external fixator of the present utility model, comprise a pair of screw rod being hinged 1, being arranged on two screw rods 1 one by one can matching thread rotation and mobile two pin clip assemblies 2, be spun on the two pairs of stop nuts 3 and the some spicules 6 that on two screw rods 1, are respectively used to fix two pin clip assembly 2 two ends, wherein:
Two screw rods 1 are hinged by hinge 5, hinge 5 comprises two hinge block 51, refer to Fig. 2, each hinge block 51 one end are fixed (especially with corresponding screw rod 1 termination, these hinge block 51 ends and screw rod 1 termination are riveted to become and are fixed as one), the other end has and holds the first screw 512 that a clamping screw 4 passes, by clamping screw 4, two hinge block 51 are locked to laminating relatively, the face of contact in the middle of two hinge block 51 periphery of the first screw 512 (that is: around) is arranged to the flank of tooth 511 simultaneously, two hinge block 51 are intermeshing by the flank of tooth 511 separately, while tightening clamping screw 4, can prevent relative sliding and rotation, having played two hinge block 51 is relatively fixed, they are become one.In addition, an elastomeric pad (not shown) is installed in the middle of two hinge block 51, and in the time unscrewing clamping screw 4, elastomeric pad separates two hinge block 51 automatically, make two hinge block 51 can, relative to rotating and moving, recover the function of hinge again.
