Description of drawings:
Fig. 1 is the structural representation of this utility model.
Fig. 2 is the side view (not containing patient's arm and pulley structure) of Fig. 1.
Fig. 3 is that A among Fig. 1 is to view.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment this utility model is detailed:
A kind of support of fixed traction angle when being used for children humeral supracondylar fracture is referring to accompanying drawing 1 to accompanying drawing 4, among the figure: the fixing holder 1 of upper arm, bottom 2, flank 3; First link, 4, the first gear rings 5, nut 6, the second gear rings 7, the second links 8; The fixing holder 9 of forearm, thread gluing 10, fixing band 11, screw 12; Pull rope 13, bearing support 14, patient's arm 15, prudent device 16, connecting band 17, pulley 18, groove 19.
In the present embodiment, first link, 4 lower surfaces in the fixing holder 1 of upper arm are provided with first gear ring 5, and second link, 8 upper surfaces in the fixing holder 9 of forearm are provided with second gear ring 7 that is meshed with first gear ring 5.
It constitutes the fixing holder of upper arm 1 first link 4 by bottom 2, flank 3 and first link 4 and is connected with bottom 2, and flank as shown in Figure 1 is made the mentioned ridge-shaped overshooting shape in order to save material.The structure of the fixing holder 9 of forearm also is made up of bottom, flank and second link 8 with the structure of the fixing holder 1 of upper arm.
The centre of gyration of first gear ring 5 and second gear ring 7 is located on the same line; This centre of gyration is equipped with screw 12; On another elongated end of screw 12 nut 6 is housed, on the outer surface of fixing holder 1 of upper arm and the fixing holder 9 of forearm fixing band 11 is housed all, thread gluing 10 all is equipped with at the both ends of fixing band 11; Can set up several fixing bands 11 according to actual needs more.
The fixing holder of upper arm 1 is connected with bearing support 14, is respectively equipped with graduated disc on first gear ring 5 and second gear ring 7, referring to the structure shown in the accompanying drawing 3; Be provided with the connecting band 17 that twines patient's arm 15 in the fixing holder 9 of forearm, connecting band 17 is connected with traction apparatus.
The preferred structure of present embodiment is that connecting band 17 is connected with prudent device 16 through pull rope 13 and pulley 18.Pull rope 13 is set on the pulley 18, and pulley 18 is connected with prudent device 16.
The somewhat larger in diameter of second gear ring 7 is in the diameter of first gear ring 5; When second gear ring 7 turns an angle with respect to first gear ring 5, see the angle value that is rotated smoothly; Nut 6 is equipped with in the lower end of screw 12; When needs fixedly the time, with locking between nut 6 and the screw 12.The fixing holder 1 of upper arm is affixed with bearing support 14.
