Abstract
The utility model relates to a jaw bone fracture reposition tractor, which comprises an elastic U shape rack; a screw arranged on the symmetry axis of the U shape rack; a spiral handle wheel arranged on the screw; and two tie rods arranged on the screw, wherein the other ends of the two tie rods are respectively connected on two arms of the U shape rack; and a traction arm arranged on each arm of the U shape rack; as well as a baffle rack arranged on the end part of the traction arm. When the utility model is adopted to carry out the jaw bone fracture healing operation with the strong inner fixation method, the traction or reposition is convenient and labor saving; and in addition, the broken bone reposition is stable after the reposition, free of any disposition phenomenon, so that the bolt screwing is quite easy, and the operation time is shortened, thus reducing the pain of the patients and playing an active role in the fast healing of the broken bone.
Description
Affiliated technical field
This utility model relates to a kind of medical apparatus and instruments, especially the jaw fracture traction apparatus that resets.
Background technology
Adopt titanium mini-plate to cut internal fixation in recent years and be also referred to as " strong internal fixation ", become the main method of clinical treatment fracture of mandible.Its objective is fracture fixation is stablized, fracture reaches anatomical reduction and apply certain axial compressive force between fracture, makes fracture line involutory closely.Earlier the titanium plate is screwed a end during operation, then with manually knochenbruch being resetted at knochenbruch.Punching on the knochenbruch of the other end by the screw hole on the titanium plate is screwed into screw, and knochenbruch is fixed.Because of the traction action of muscle group, manual reset is difficulty relatively.After the knochenbruch punching of back punching any moving can not be arranged, otherwise screw can't be screwed into.Artificial is knochenbruch position stability extreme difference.Chang Yinwei titanium plate hole and the dislocation of bone hole when preparing screw make being screwed into of screw very difficult.Prolonged operating time, increased patient's misery, for the healing of knochenbruch brings negative effect.
Summary of the invention
Be to solve the problem of manual reset difficulty, artificial position stability difference, this utility model provides a kind of jaw fracture traction apparatus that resets.This utility model only need rotate a small handwheel knochenbruch is resetted during operation, and the back knochenbruch positioning stablity that resets, and the phenomenon that is shifted can not occur.
The technical scheme that this utility model technical solution problem is adopted is: invent a kind of jaw fracture traction apparatus that resets, be characterized in that the jaw fracture traction apparatus that resets has a resilient U-shaped frame, a screw rod is installed on the axis of symmetry of U-shaped frame, a spiral handwheel is installed on the screw rod, hinged two pull bars on the screw rod, the other end of two pull bars is hinged on respectively on two arms of U-shaped frame.
The beneficial effects of the utility model are that when use this utility model carried out jaw fracture treatment operation in " strong internal fixation " method of employing, reduction by traction was convenient, laborsaving.And the back knochenbruch positioning stablity that resets the phenomenon that is shifted can not occur.Make being screwed into of screw very easy.Operating time shortens, and has reduced patient's misery, for the quickly-healing of knochenbruch plays positive role.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Accompanying drawing 1 is the front view of embodiment, and accompanying drawing 2 is vertical views of embodiment, and accompanying drawing 3 is application diagrammatic sketch of embodiment;
Among the figure: 1-spiral handwheel, the 2-screw rod, 3-U shape frame, 4-screw rod hinge, the 5-pull bar, 6-U shape frame hinge, the 7-draft arm, 8-blocks frame, 9-mandibular bone, 10-traction screw, 11-fracture line, 12-titanium plate, 13-hold-down screw;
The specific embodiment of embodiment
As shown in Figure 1, spiral handwheel 1 is installed on the screw rod 2, screw rod 2 is through in the U-shaped frame 3 vertical holes, it is hinged with two pull bars 5 to penetrate screw rod hinge 4 in the hole of the other end of screw rod 2, the other end of two pull bars 5 is hinged with two arms of U-shaped frame 3 respectively by U-shaped frame hinge 6, draft arm 7 and block frame 8 and join together with U-shaped frame 3, when when the direction of U-shaped frame 3 is rotated spiral handwheel 1, two arms that 5, two pull bars of screw rod 2 two pull bars of pulling 5 inwardly spur U-shaped frame 3 drive draft arms 7 and block frame 8 and inwardly draw in.When rotating spiral handwheel 1 round about, two pull bars 5 are loosened, and two arm drives draft arm 7 and blocks frame 8 and outwards opens under the elastic force effect of U-shaped frame 3.Applicable cases as shown in Figure 3, during operation the fracture soft tissue peeled off and expose mandibular bone 9, on titanium plate 12 usefulness hold-down screws 13 fixing knochenbruch at one end, one of them hold-down screw 13 is screwed into 2/3 and reserves one section and be used for hanging draft arm 7, punching is screwed into traction screw 10 and reserves 1/3 on the lead slightly at a distance of other end knochenbruch, then the angle of draft arm 7 by most convenient is hung on the screw at fracture line 11 two ends, with blocking frame 8 soft tissue of peeling off is kept off outside draft arm 7, inwardly rotating screw handwheel 1 is implemented to draw to 11 pairs of fracture lines tight.By the screw position on the titanium plate 12 punching and be screwed into hold-down screw 13.Last outwards rotating screw handwheel 1 loosens draft arm 7 it is taken off, and the hold-down screw 13 that is screwed into 2/3 is tightened, and backs out traction screw 10, sews up soft tissue, and operation finishes.
