Summary of the invention
The object of the present invention is to provide a kind of Orthopaedic external fixator, can realize the variation of angle, relative to prolongation, cripetura with rotate, thereby reach the location of different directions length and angle, simple in structure, easy to adjust.
The technical scheme that realizes above-mentioned purpose is:
An Orthopaedic external fixator, comprises a pair of screw rod being hinged, is arranged on two pin clip assemblies on described two screw rods, two pairs of stop nuts and some spicules one by one, wherein:
Each pin clip assembly comprises the upper piece of pin folder, the lower piece of pin folder and some screws,
The lower piece of described pin folder is provided with the second screw perforation and that pass for described screw rod, and every pair of stop nut is spun on respectively on the screw rod of the lower piece of described pin folder both sides;
The lower piece of the upper piece of described pin folder and pin folder is fixed by described some screw in compressions, under the upper piece of described pin folder and pin folder, piece touches on face and all has several needle track grooves mutually, the upper piece of described pin folder and the lower piece of pin folder needle track groove are separately corresponding one by one, are harmonious up and down and are formed for the needle track of fixing described spicule.
In above-mentioned Orthopaedic external fixator, described two screw rods are hinged by a hinge, and described hinge comprises two hinge block,
Each hinge block one end is fixed with the termination of corresponding described screw rod, the other end has and holds the first screw that a clamping screw passes, by described clamping screw, described two hinge block are locked to laminating relatively, in the middle of described two hinge block, the face of contact is arranged to two intermeshing flank of tooth.
In above-mentioned Orthopaedic external fixator, in the middle of described two hinge block, an elastomeric pad is installed.
In above-mentioned Orthopaedic external fixator, the termination riveted joint of described each hinge block one end and corresponding described screw rod.
In above-mentioned Orthopaedic external fixator, the face of contact in the middle of described two hinge block, around the periphery of the first screw.
In above-mentioned Orthopaedic external fixator, the upper piece of described pin folder is provided with the some through holes that equate with described screw number, the lower piece of described pin folder is provided with and described through hole some slotted eyes of Corresponding matching one by one, and through hole and slotted eye are combined into some the 3rd screws that screw in for each screw one to one for these.
The invention has the beneficial effects as follows: the present invention 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, the present invention is simple in structure, has high practical value.
Accompanying drawing explanation
Fig. 1 is the structure chart of Orthopaedic external fixator of the present invention;
Fig. 2 is the structure chart of hinge block in the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 1, Orthopaedic external fixator of the present invention, 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 is 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, when unscrewing clamping screw 4, elastomeric pad, automatically by two hinge block 51 separation, makes two hinge block 51 can, relative to rotating and moving, recover the function of hinge again.
Each pin clip assembly 2 includes the upper piece 21 of pin folder, the lower piece 23 of pin folder and some screws 22, wherein: the lower piece 23 of pin folder is provided with the second screw perforation and that mate with screw thread on screw rod 1, screw rod 1 is through the second screw, make the lower piece 23 of pin folder to rotate, to move with respect to screw rod 1, every pair of stop nut 3 is spun on respectively on the screw rod 1 of the lower piece of pin folder 23 both sides, plays spacing effect;
The upper piece 21 of pin folder is provided with the some through holes with screw 22 quantity equality matchings, the lower piece 23 of pin folder is provided with and some through holes some slotted eyes of Corresponding matching one by one, these one to one through hole and slotted eye be combined into some the 3rd screws that screw in for each screw 22, thereby make the upper piece 21 of pin folder fixing with respect to the lower piece 23 of pin folder.Under the upper piece 21 of pin folder and pin folder, piece 23 touches on face and all has several needle track grooves mutually, the upper piece 21 of pin folder and the lower piece 23 of pin folder needle track groove are separately corresponding one by one, be harmonious up and down and be formed for the needle track of fixed bone spicule 6, by rotating each screw 22, the upper piece 21 of pin folder is moved with respect to the lower piece 23 of pin folder, thereby compress spicule 6 or unclamp.
To sum up, each above-mentioned spare part material therefor is all metal material.The present invention can realize the variation of angle by hinge, and movement and rotation by two pin clip assemblies on threaded rod can realize relative to prolongation, cripetura and rotate, and finally can reach the location of different directions length and angle, simple in structure, easy to adjust.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
