SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides a skull dislocation draw gear, realizes that the dislocation in skull both sides is fixed, promotes the adaptability to patient's skull side defect.
In order to solve the technical problem, the utility model discloses a technical scheme be: provided is a skull dislocation traction device, comprising: the U-shaped traction frame comprises a threaded sleeve, a locking nut, a screw and an opening, wherein the opening points to the lower side, clamping plates are respectively arranged at two ends of the bottom of the U-shaped traction frame, a threaded sleeve penetrating groove is formed in each clamping plate, the threaded sleeve is arranged in the threaded sleeve penetrating groove, the locking nut is arranged on the threaded sleeve and positioned on two sides of each clamping plate, and the screw is arranged in the threaded sleeve and points to the inner side of each clamping plate.
In a preferred embodiment of the present invention, the thread bushing penetrating groove is a cross groove or a straight groove.
In a preferred embodiment of the present invention, the threaded sleeve has a threaded hole corresponding to the screw.
In a preferred embodiment of the present invention, the outer circle of the thread bushing is provided with an external thread corresponding to the lock nut.
In a preferred embodiment of the present invention, a pull ring is disposed on the top of the U-shaped traction frame.
In a preferred embodiment of the present invention, a support rod is transversely disposed in the U-shaped traction frame above the clamping plate.
The utility model has the advantages that: the utility model provides a skull dislocation draw gear, through the regulation of thread bush in the thread bush runs through the groove for the directional skull side non-defective part of screw, rethread lock nut locks, realizes that the screw is fixed in the dislocation of skull both sides, and is easy and simple to handle, has promoted the adaptability to patient's skull side defect, is favorable to more patients' skull to pull.
