The invention provides a spinal scoliosis orthopedic device. The spinal scoliosis orthopedic device comprises an upper shell; a lower shell, wherein the lower shell and the upper shell are arranged ina nested mode, and the opening of the upper shell and the opening of the lower shell face opposite directions; a first screw; a second screw, which is arranged on the lower shell in a penetrating manner; an orthopedic structure, which is arranged between the upper shell and the lower shell and comprises a first upper connecting rod and a first lower connecting rod, wherein the first end of the first upper connecting rod is hinged to the upper shell, the first end of the first lower connecting rod is hinged to the lower shell, and the second end of the first upper connecting rod is hinged to the second end of the first lower connecting rod through a first hinge piece; and a driving device, which comprises a driving structure and a screw rod driven by the driving structure. The screw rod penetrates through the first hinge piece, and the driving structure drives the screw rod to rotate so as to drive the first hinge piece to move along the screw rod, so that the upper shell and the lowershell are far away from each other. The problem that in the prior art, a plurality of screws are used for fixing long segments in multi-segment vertebral fusion, and the movement is limited is effectively solved.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to a scoliosis adjustment device. Background technique [0002] Adolescent idiopathic scoliosis (AIS) refers to the structural scoliosis of the spine that occurs in adolescence without other organic diseases, and is the most common scoliosis deformity. AIS patients have a scoliosis angle greater than 10° on the coronal plane. With the rapid progress of the natural course, the scoliosis angle increases and the appearance of the spine and thorax deforms, which affects the heart and lung functions, causing serious harm to the physical and mental health of the children. serious burden on children's families and society. [0003] There are various methods for the treatment of AIS, which can be classified into non-surgical treatment and surgical treatment. Non-surgical treatment is suitable for children with early diagnosis, mild disease and low risk of curve progression. Children wi...
