Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the examples.

[0021] figure 2 , Figure 4 Shows the non-contact electromagnetically driven non-invasive growth rod provided by the present invention, including the electromagnetically driven extension and retraction mechanism 1 in the body, which is used to connect between the apical and caudal vertebrae of the spine, and the electromagnetically driven extension and retraction mechanism 1 in the body can Driven by the controlled electromagnetic field, it protrudes and lengthens or retracts and shortens to realize the support of the concave side of the spine or the compression of the convex side, thereby completing the dynamic correction of scoliosis.

[0022] In a preferred embodiment, as figure 2 As shown, the electromagnetically driven retractable mechanism 1 in the body is extended or retracted in one direction, that is, the electromagnetically driven retractable mechanism 1 in the body...

Abstract

The invention relates to a non-contact electromagnetic-drive noninvasive growing rod for scoliosis correction. The non-contact electromagnetic-drive noninvasive growing rod comprises a in-vivo electromagnetic-drive extension mechanism connected between the apical vertebra and the caudal vertebra and can extend or retract under driving of in-vitro control electromagnetic field to achieve supportingto lateral concave or pressurizing to lateral convex of the vertebral column so as to complete dynamic correction of scoliosis. Compared with the prior art of growing rods, the non-contact electromagnetic-drive noninvasive growing rod has the advantages that it can achieve scoliosis correction for patients who reject the invasive surgical operation, reduce surgical wound and incidence rate of other complications such as respiratory tract infection and risk of anesthesia caused in frequent operations, and also decrease financial burden; besides, it can be opened slightly frequently, which canreduce ligamentous and spinal injury caused by spine rigidity and spontaneous fusion as compared with the conventional disposable violet opening; and it ca complete opening even when the patient is ina waking state, nerve testing is omitted, and safety is improved.

Description

technical field [0001] The invention relates to a medical device, in particular to a non-contact electromagnetically driven non-invasive growth rod for scoliosis correction. Background technique [0002] Children's scoliosis is a kind of orthopedic deformity that seriously affects children's growth and development. The impact on children is not only the appearance, but when the deformity is serious, scoliosis will also have a great impact on cardiopulmonary development. Surgery should be considered when scoliosis in children is not suitable for non-surgical treatment or non-surgical treatment can not stop the scoliosis from worsening. The development of modern spine surgery has extended the treatment of scoliosis to three-dimensional space, that is, the treatment of three-dimensional structures in coronal, sagittal and horizontal positions. However, this is still not enough in the treatment of scoliosis in children, children also have a fourth dimension, that is, children's...
