Problems solved by technology
[0008] The present invention constructs a spinal orthopedic system that can provide growth freedom by combining earring nails, adjustment screws and orthopedic rods, and solves the problem that when the existing orthopedic systems are used for spine orthopedics in infants and children, the growth of the spine is limited, or it needs to be repeated. The problem of multiple propping operations

Embodiment 1
[0025] Example 1: In the orthopedic spine of infants or children, the lower end is fixed with one locking hole (i.e. single earring) or with two locking holes (i.e. double earrings), and the rest are fixed with earring nails, and the orthopedic rod can be attached to the earrings The sliding fit of the nails slides in the holes, and the orthopedic rods do not constrain the growth of the spine.
Embodiment 2
[0026] Example 2: When there are significant teratogenic factors, such as poor vertebral body formation or segmental insufficiency, use one locking hole (i.e. single ear nail) or two locking holes (i.e. double earrings) for fixation, and the rest are fixed with earrings. The orthopedic rod can slide in the ring of the earrings, and the orthopedic rod does not restrict the growth of the spine.
[0027] In the above embodiments, after the locking screw of the adjusting screw is loosened, the orthopedic rod can slide in the sliding fitting hole of the adjusting screw.
[0028] One or more sets of the device can be placed in the spine of a child at the same time or in stages.

The invention discloses a low-incisura orthopedic device capable of promoting free growth of a spine. The low-incisura orthopedic device comprises an orthopedic rod, a locking screw, earring nails and an adjusting screw, wherein the earring nails are in sliding fit with the orthopedic rod, and the adjusting screw is in locking fit or sliding fit with the orthopedic rod. The adjusting screw is provided with a locking hole in thread fit with the locking screw and comprises an earring portion, a threaded rod and a locking block, and the earring portion is provided with a sliding fit hole formed in the locking block. The low-incisura orthopedic device has the advantages that the earring nails and the adjusting screw are used with the orthopedic rod to construct a spine orthopedic system capable of providing growth freedom degree, and the problem of limitations on spine growth or need for repeated distraction operations when an existing orthopedic system is used for spine correction of infants and children is solved; by means of sliding between the orthopedic rod and the earring nails as well as between the orthopedic rod and the sliding fit hole of the adjusting screw, one deformed spine is guided to grow along the normal direction, and restraints on spine growth are avoided.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a low-profile orthopedic device with simple structure, easy operation and the ability to provide free growth of the spine. Background technique [0002] Spinal deformity refers to the curvature of one or several segments of the spine away from the midline of the spine, usually accompanied by rotation of the vertebral bodies and increased or decreased kyphosis or protrusion on the sagittal plane. It is a three-dimensional spinal deformity with an incidence of about 0.5-2% in adolescents and can be caused by various diseases. When the angle of scoliosis is too large, or shows a clear trend of progress, surgical treatment needs to be considered; otherwise, it will gradually develop into a severe and rigid spinal deformity, which will seriously affect the heart and respiratory function of the child, and affect the spinal cord function leading to paralysis. Even l...
