Non-operative treatment.Conventional non-operative treatment means are with clamping plate plaster fixing and using fixed in Kirschner wire at present.Using closing
Suitable pin often results in neural blood vessel damage.And clamping plate plaster fixing, it is often necessary to which extremely bent position in the wrong is fixed, and is added forearm and is lacked
The risk of courageous and upright muscular contraction.
The content of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of supracondylar fracture of humerus reseting fixture, leads to
Replacement and fixation can be realized by crossing the device, and and can effectively avoids the generation of ischemic contracture.
The purpose of this utility model is achieved through the following technical solutions：
A kind of supracondylar fracture of humerus reseting fixture, including c-type upper arm supporting bracket tool, c-type forearm supporting bracket tool are described
Upper arm supporting bracket has to be connected between forearm supporting bracket tool by hinge；The upper arm supporting bracket tool upper end is connected with the upper of ring-type
Fixture, the forearm supporting bracket tool lower end are connected with the lower fixture of ring-type, set between fixed part and lower fixture
There is telescopic draw bar, the draw bar both ends are hinged with upper fixing element and lower fixture, are arranged on the draw bar respectively
There is elastic adjustable support collar, be hinged with telescopic connecting rod on the support collar, the other end of the connecting rod is hinged
There is the location-plate of arc；The support end that the upper arm supporting bracket tool includes the fixing end being vertically arranged and arc is set, it is described solid
Fixed end is integrally formed with support end, and both sides offer screwed hole on the support end of the upper arm supporting bracket tool, can on the inside of support end
Dismounting is connected with the liner consistent with support end shape.
Preferably, the angle between the fixing end and support end is 140o.
Preferably, the elastic reducing-fixing band no less than one is equipped with the upper arm supporting bracket tool and forearm supporting bracket tool.
After the setting of elastic reducing-fixing band can ensure replacement and fixation so that upper arm supporting bracket has and forearm supporting bracket tool is brought into close contact with arm
It is fixed.
Preferably, upper arm supporting bracket tool and forearm supporting bracket tool using can X-ray thoroughly material.It is easy in C arm machine
Under carry out fracture rectification and recovery fix.
The beneficial effects of the utility model：Upper arm supporting bracket has to be connected between forearm supporting bracket tool by hinge, and on
Telescopic draw bar is hinged between fixture and lower fixture, stretching and drawing bar can drive forearm movable back and forth, be closed
Flexion-extension motion is saved, the generation of ischemic contracture can be effectively avoided, beneficial to the recovery as early as possible of patient's function；It is arranged with draw bar
Elastic adjustable support collar, described support are hinged with telescopic connecting rod on the collar, and the other end of the connecting rod is hinged with
The location-plate of arc, therefore position of the support collar on draw bar can be adjusted, adjust the length of connecting rod so that connecting rod is withstood
Location-plate, the location-plate is placed on the inside of condyle of humerus elbow joint, plays Auxiliary support positioning；Upper arm supporting bracket tool includes
The support end that the fixing end and arc being vertically arranged are set, the angle between curved support end and the fixing end being vertically arranged are
140o, the setting of angle cause this supporting bracket tool more to meet skeleton structure, that is, meet the angle between upper arm and condyle of humerus
Relation；Both sides offer screwed hole on the support end of upper arm supporting bracket tool, are removably connected with and support on the inside of support end
The consistent liner of shape is held, in use, passing through two screwed holes with screw, by adjusting two bolts, withstands liner, and then rectify
Supination deformity before the rotation of positive supracondylar fracture of humerus.
The present apparatus is simple in construction, fixed, easy to use, is easy to adjust, and not only realizes answering for supracondylar fracture of humerus
Position is fixed, while effectively prevent the generation of ischemic contracture.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is the structural representation of upper arm supporting bracket tool.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
