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. Background technique [0002] Hip dislocation in children is one of the more common congenital deformities. It is more common in the future and exists at birth. There are more females than males, about 6:1, the left side is twice as much as the right side, and the bilateral side is less. Due to the congenital dysplasia or abnormality of the acetabulum, femoral head, joint capsule, ligaments and nearby muscles, joint laxity, subluxation or dislocation are caused. In addition, the abnormal position of the fetus in the uterus and excessive flexion of the hip joint are also prone to cause this disease , In addition, genetic factors are not obvious. The clinical manifestations of newborns and infants are mild, and the symptoms are often not obvious. When the following signs are found, the possibility of congenital dislocation of the hip joint sho...
