The device is used as follows:

1. The installation personnel vertically installs the sliding rail on a wall surface suitable for the trauma department, preferably, the lower end is 800mm away from the ground, when no patient exists, the sliding rail can be arranged on the wall side by the upper locating pin, when the patient exists, the whole sleeve body height can be adjusted appropriately by the upper locating pin and the lower locating pin according to the height of the patient, and meanwhile, the elbow joint of the injured arm of the patient is fixed at the position of the arm sleeve I;

2. When the patient is right (left) ulna fracture, the upper and lower locating pins are drawn off, and the device is turned upside down and exchanged; when the affected arm is Ke Leishi fracture (namely the broken end shifts to the palm side or angulates), the traction belt force points are bound on the palm back side of the palm; when the affected arm is a Schmitt fracture (namely the broken end shifts to the back side of the hand or is angled), the traction belt force points are bound on the palm center side of the palm; when the palms and wrists of the affected arms are tiny or abnormal, the medical elbow joints are fixed in an arm sleeve II (also called a medical elbow joint sleeve), at the moment, the palms and wrists of the affected arms are gripped by hands of doctors, and are fixed by binding bands, so that a patient of orthopedics can control electric traction and reduction after traction;

3. When the orthopedics and the traumatology consider that the reduction can be carried out after the traction, X-ray observation is needed after the reduction, the whole sleeve body and the fixed affected arm are taken out from the groove steel frame of the wall body, the X-ray machine is used for perspective or shooting, after the satisfactory reduction effect is achieved, the traction is slowly relaxed under perspective, and the fracture arm (plaster, splint and the like) can be externally fixed without dislocation.

The device has the following characteristics:

1. The traction work which is originally completed by 3-4 persons can be completed by only 1 doctor using the device, the defect of insufficient hands is overcome, and the manpower resources are saved;

2. Compared with manual traction, the electric traction has the advantages of strong traction force, uniform force and good controllability, can stably maintain for a long time, and is beneficial to the smooth treatment of doctors;

3. The traction belt binding method is suitable for different fracture forms, can ensure that the traction force is accurate, can completely act on fractured ulna and radius, keeps the state of the affected arm stable after the traction is finished, is convenient for X-ray machine perspective or film shooting, and is also convenient for the subsequent diagnosis, external fixation plaster making and other works to be carried out smoothly;

4. The elbow joint arm sleeve of the device is made of arc-shaped flexible materials matched with the appearance of the arm, discomfort of a patient is reduced, and the detachable design is used for matching patients and medical staff with different arm thicknesses by replacing elbow joint arm sleeves of different models.

In summary, the technical proposal can save people and labor, can exert the action force on the traction of fractured ulna and radius, and can facilitate the orthopedics to put on the auxiliary instrument of X-ray machine perspective or film shooting at will after reduction, namely, the orthopedics can easily finish the work of traction, reduction, X-ray machine diagnosis, external fixation plaster making and the like of the fracture dislocation ulna and radius. Has very good application prospect.
