Problems solved by technology

[0002] At present, the application of posterior three-dimensional orthopedic fusion technology in the treatment of scoliosis has been widely carried out at home and abroad. The most commonly used orthopedic devices, such as: CDH, TSRH, Moss Miami, USS, etc., are mainly researched and designed for adult patients. For children or adolescent scoliosis patients in the growing period, in order to increase the height as much as possible, there is a method of using the above-mentioned devices plus a "growth regulating valve" in surgical treatment, but surgery is required every six months to one year. At the same time, in cases where height growth is not emphasized, the posterior orthopedic fusion of scoliosis in the growth period still has the possibility of "crank phenomenon" leading to orthopedic failure

Embodiment Construction

[0019] Such as figure 1 , figure 2 , image 3 As shown, the whole system of the present invention consists of growth regulator rods ( figure 1 ), slidable pedicle screw ( figure 2 ), ordinary pedicle screw ( image 3 )composition. Among them, the slidable pedicle screw ( figure 2 )Depend on Figure 4 The external fixation screw 1, the fixation cap 2, the internal fixation screw 3 and the slidable pedicle screw body 4 shown in the figure are composed of four parts. When used, the Growth Regulator ( figure 1 ) The lower third of the tapered section and the internal fixation screw 3 are fixed by point contact, because the growth adjustment rod ( figure 1 ) The diameter of the lower third of the segment is tapered and smooth. After being fixed with the internal fixation screw 3, only the slidable pedicle screw ( figure 2 ) slides distally so that the slidable pedicle screw ( figure 2 ) can move to the distal end with the growth of the spine, which can not only produ...

Abstract

The invention discloses a special apparatus for correcting scoliosis deformity in a growth period, which consists of a growth regulation bar, a sliding vertebral pedicle bolt and a common vertebral pedicle bolt. The special apparatus has the function of automatically sliding to the far end along with the growth of a vertebral column, does not affect the longitudinal growth of the vertebral column, prevents a sick child from suffering from pain of repeated regulation operation, and further improves the curative effect of surgical posterior correction of the scoliosis in the growth period.

Description

technical field [0001] The invention relates to a medical device for orthopedic scoliosis correction, in particular to a special orthopedic device for scoliosis patients in growth period. Background technique [0002] At present, the application of posterior three-dimensional orthopedic fusion technology in the treatment of scoliosis has been widely carried out at home and abroad. The most commonly used orthopedic devices, such as: CDH, TSRH, Moss Miami, USS, etc., are mainly researched and designed for adult patients. For children or adolescent scoliosis patients in the growth period, in order to increase the height as much as possible, there are methods of using the above-mentioned devices plus a "growth regulating valve" in surgical treatment, but surgical braces need to be performed every six months to one year. At the same time, in cases where height growth is not emphasized, the posterior orthopedic fusion of scoliosis in the growth period still has the possibility of ...
