Correction device for congenital thoracolumbar disc herniation in children under 3 years old

摘要

Under the background of spinal hypoplasia in children under 3 years old, the correction device for congenital thoracolumbar disc herniation was designed,Including: trans medical screw (1),It was installed outside the abnormal area of the posterior spine;The rod (6),Connect the Cross medical screw (1). The task of the useful model is to improve the reliability of the support unit and the effectiveness of correcting congenital spinal deformity. The technical results of this task are achieved throughThe rod (6) is provided with side holes (9) with a depth of 0.4 mm, a diameter of 1.4 mm and a spacing of 4 to 8 mm,Each hole (9) is reversely slotted on the other side (6) of the rod, and each hole (10) is reversely slotted twice perpendicular to the longitudinal axis (6) of the rod,The vertical side groove bottom (5) bushing (4) provides a convex part (11) to ensure close contact with the response shape groove (10) rod,The inner nut (8) of the two-component holder,Conical response for close contact with the drill (9) rod (6).
