Adjustable child femoral fracture suspension traction system and control method

Abstract

The invention belongs to the technical field of fracture suspension traction devices, and discloses an adjustable child femoral fracture suspension traction system and a control method. Supporting columns are fixed to two sides of a baseboard bed through bolts, the supporting columns are hollow, a support is fixedly sleeved with the supporting columns through metal spring cotters, two sets of pulley assemblies are movably arranged on the support, foot plates are connected with the lower sides of the pulley assemblies through slings, and air pressure suspension devices are arranged on the lowersides of the foot plates; and the baseboard bed comprises a rectangular plank, a soft mattress is arranged on the upper side of the rectangular plank, a metal frame is arranged on the periphery of the soft mattress, guard bars are arranged on two sides of the mattress, and an ilium band is arranged on the upper side of the middle portion of the mattress. According to the adjustable child femoralfracture suspension traction system and the control method, the structure is simple and reasonable, multi-angle traction can be achieved through the foot plates and the air pressure suspension devices, rotation deformity and lateral angulation deformity can be corrected controllably, a child patient is fixed by the ilium band, and secondary injury due to squirming of the child patient is prevented, so that the safety is high.

Description

technical field [0001] The invention belongs to the technical field of suspension and traction devices for fractures, and in particular relates to an adjustable suspension and traction system for children with femur fractures and a control method. Background technique [0002] Currently, the femur is the largest tubular bone in the human body, surrounded by abundant muscles. During development, the femur forms a lordosis, with pressure on the inside and tension on the outside. Femoral shaft fractures in children are common clinical fractures. There are three main treatments for this disease: traction, external fixation, and internal fixation. For children under 5 years old, suspension skin traction is often used. [0003] Suspension skin traction is to draw the lower limbs with the skin, and both legs go up at the same time, adjust the traction weight until the buttocks are slightly away from the bed, and use the weight of the body as the anti-traction. [0004] At present...

AI Technical Summary

Problems solved by technology

[0007] (1) The traction direction of the traditional retractor is single, and it is impossible to correct the rotational deformity in a controllable manner, and it is also unable to correct the lateral angular deformity in a controllable manner;

[0008] (2) The traction force is not constant. When the child is crying and active, the resistance to the traction force increases, which often causes skin blisters and even skin tearing;

[0009] (3) The randomness of traction is large, which is not conducive to the healing of fractures, and may cause skin ulcers, infections and other problems in children
