Problems solved by technology

At present, the method of extensible rods for the treatment of scoliosis in children has been proposed, such as the "bayonet-shaped" sleeve method and the Isola growth valve method, and other correction methods have appeared one after another, but their disadvantage is that they still need to be treated every 6 months to 1 year. Re-operation to extend the distraction will inevitably make children suffer from multiple operations, and also increase the financial burden of patients

Embodiment 1

[0019] attached figure 1 , 2 Different forms of the present invention are composed of different forms of connectors. And in each form, titanium rods are equipped with springs according to actual surgical needs. The present invention consists of a titanium rod 1, a spring 2, a fixable connector 6 or 7, a locking screw 5, a pedicle screw 4 and a screw plug 3.

[0020] figure 1 A system composed for use of double-row parallel connectors6. One end of the two titanium rods 1 passes through the two through holes of the double-row parallel connectors 6 respectively, and the connectors are fixed to the vertebral body by locking screws 5 . There are many forms of assembly springs with double-row parallel connectors, and the upper end assembly is as follows: figure 1 A, or lower end assembly such as figure 1 B, or both ends are assembled such as figure 1 c. Choose according to the actual case, put the spring into the titanium rod, and press it tightly on the connector joint 6. ...

Abstract

The invention relates to a power-driven automatic stretching correcting system and application thereof. The power-driven automatic stretching correcting system comprises two titanium rods, springs, a fixable connector, a locking screw, pedicle screws and plug screws. One ends of the two titanium rods are connected by the connector and are fixed to a vertebral body through the locking screw. Each of the other ends of the two titanium rods is fixed to the vertebral body through one pedicle screw with one plug screw. Connectors can be added according to needs. Springs can be disposed on the titanium rods. One end, away from the corresponding pedicle screw and extending out of the connector, of each titanium rod is a sliding free end. The invention further discloses application of the correcting system in the technical field of children scoliosis correction and fixation. The power-driven automatic stretching correcting system has the advantages that stable internal fixation can be achieved by the screw-rod system, automatic stretching of the system can be kept by extension of the springs on the titanium rods and sliding between the titanium rods and the connectors, a growth function of a spine can be kept without multiple extending operations, correcting effect for scoliosis can be well kept, and complication incidence rate can be reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of orthopedic medical devices, in particular to a dynamic automatic distraction orthopedic system and its application. 【Background technique】 [0002] In recent years, with the in-depth understanding of the three-dimensional deformity of scoliosis and the development of spinal internal fixation technology, the surgical correction effect of adolescent scoliosis has made significant progress. From the early Harrington correction method, Luque correction method, Harrington-Luque combined method, to the later anterior derotation scoliosis correction and three-dimensional correction (such as C-D surgery, CDH surgery), surgical operations are becoming more and more easy to correct, The correction effect is getting better and better. However, the treatment of scoliosis in children who still have great potential for growth and development is still a difficult problem in the field of spinal surgery. For these pat...
