Technical Field
The invention belongs to the technical field of fracture suspension traction devices, and particularly relates to an adjustable children femoral fracture suspension traction system and a control method.
Background
At present, the femur is the largest tubular bone in the human body, surrounded by thick muscles. In the process of development, the femur forms a lordosis, the inside bears pressure, and the outside bears tension. Femoral fracture of children is a common fracture in clinic, and the treatment of the fracture mainly comprises 3 types of traction, external fixation and internal fixation, while suspension skin traction is mostly adopted for children under 5 years old.
The suspension skin traction is to pull the two lower limbs with skin, the two legs are upward at the same time, the traction weight is adjusted until the buttocks are slightly separated from the bed surface, and the body weight is used as the counter traction.
The conventional suspension retractors have many disadvantages, wherein the traction direction is single and skin tearing and peeling injuries can be caused. The traditional tractor has a single traction direction, cannot controllably correct the rotation deformity, and cannot controllably correct the lateral angulation deformity; and the traction force is not constant, and when the sick child cry and moves, the contrast traction force is increased, which often causes skin blisters and even skin avulsion.
More doctors and parents are more inclined to choose a treatment using vertical suspension traction when a fracture of the femoral shaft occurs in children. However, the treatment method has large traction randomness because no special treatment instrument exists, is not favorable for healing of fracture, and can cause problems of skin ulceration, infection and the like of children patients. Therefore, a special suspension traction instrument for treating the femoral fracture of the child is urgently needed clinically, so that the maximum clinical curative effect of treating the femoral fracture of the child through suspension traction is ensured.
Through the above analysis, the problems and defects of the prior art are as follows:
(1) the traditional tractor has a single traction direction, cannot controllably correct the rotation deformity, and cannot controllably correct the lateral angulation deformity;
(2) the traction force is not constant, and when the sick child cries and moves, the resistance to the increase of the traction force often causes skin blisters and even skin avulsion;
(3) the traction randomness is high, which is not only not beneficial to the healing of the fracture, but also can cause the problems of skin ulceration, infection and the like of the children patients.
