Infant hip joint fixable connecting rack

Abstract

The invention provides an infant hip joint fixable connecting rack. The connecting rack is characterized by comprising a crossed rack, wherein the crossed rack is connected with a universal head; a rotary fixed cap is arranged between the crossed rack and the universal head and is connected with a rotary seat, and the universal head is fixed in the cavity of the rotary seat; an eccentric shaft is arranged in the rotary seat, a chain wheel A is arranged on one side of the rotary seat, and is matched with a chain wheel B on an I-shaped rack. The fixable connecting rod has an effect of conveniently connecting and fixing, and is advantageous to extension, flexion and abduction of the hip joint, so that normal development of a patient cannot be influenced, muscle atrophy can be effectively avoided, pains of patients can be relieved and easily accepted, irritating friction of the acetabular head is benefited, development of the acetabular head is promoted, re-dislocation is prevented, and the use effect is good.

Description

technical field [0001] The invention relates to a medical product, in particular to a fixed connection frame for children's hip joint.

Problems solved by technology

[0003] At present, doctors will use lockable external fixator to fix the position of children's hip joint after hip dislocation, but after using lockable external fixator, some children's acetabular development is still poor, and severe cases after dislocation and reduction Can lead to necrosis of the femoral head, can cause disability in children
