Problems solved by technology

[0003] The staged distraction operations of the existing corrective devices all have the characteristics of large wounds and the need for general anesthesia, which not only makes the time interval for each distraction operation long, but also cannot achieve better braces in a timely and reasonable manner according to the growth of the child. Moreover, due to the large surgical wound and the need for general anesthesia, there are great risks and adverse effects in the operation. For example, repeated general anesthesia has adverse effects on children's physical strength and intelligence, and it is easy to cause nerve damage or dural damage during the operation. Complications, etc.

Embodiment Construction

[0027] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] figure 1 It is a structural schematic diagram of the scoliosis correction device of the present invention. Such as figure 1 As shown, the scoliosis correction device includes a support cylinder 1 , an upper expansion rod 2 and a lower expansion rod 3 arranged in the support cylinder 1 . The support tube 1 is a hollow cylinder, the upper expansion rod 2 and the lower expansion rod 3 are solid cylinders, and the lower end of the upper expansion rod 2 and the upper end of the lower expansion rod 3 are respectively sleeved on the upper end and the lower end of the support tube 1 Inside. In corrective surgery, the upper end of the upper expansion rod 2 and the lower end of the lower expansion rod 3 are respectively fixed on the upper and lower lamina of the spine by pedicle screws ( figure 1 not shown). The support cylinder 1 is provi...

Abstract

A correcting appliance for the scoliosis is composed of a hollow cylindrical supporting pipe, two expanding rods movable in said supporting pipe, and the fixing structure and regulating structure of said expanding rods, which are arranged on external surface of said supporting pipe.

Description

technical field [0001] The invention relates to an internal fixation device for treating scoliosis, in particular to an internal fixation device for treating children's scoliosis. Background technique [0002] Children's scoliosis is divided into progressive and non-progressive types. The progressive type has severe lesions and rapid development of deformities. If it is not treated in time, it will affect the development of various organs in the abdominal cavity and lead to aggravated spinal deformities. Plus spinal fusion, it will seriously affect the normal development and growth of children. The current approach is simply to perform internal fixation of spinal instruments to maintain the growth of the spine, and to postpone spinal fusion. However, the fixation device needs to be stretched in stages in the later stage to continuously adapt to the growth of the child's spine and achieve the effect of stretching on the concave side of scoliosis. The above-mentioned staged ...
