Description

Scoliosis correcting component capable of automatically adjusting along with growth of spine

Technical Field

The invention relates to a correcting component for scoliosis, in particular to a correcting component for scoliosis, which can be automatically adjusted along with the growth of a vertebra.

Background

The scoliosis is caused by long-term poor posture, and the natural scoliosis is caused after birth. If the scoliosis occurs in the adult (bone no longer grows) stage, the correction and fusion fixation can be performed by surgery to obtain good treatment effect. However, if the lateral curvature of the spine occurs in the growth stage of young children or juveniles, the above correction method and apparatus using the fusion fixation operation are not applicable because the spine of the patient continues to grow in the growth stage.

For patients with scoliosis in the growth stage, the current medical proposal is to perform surgical correction when the scoliosis exceeds 45 degrees or is severely pressed to the heart and lung functions, and the current spinal scoliosis corrector suitable for the stage is all necessary to perform multiple operations according to the growth speed of the patient so as to adjust the corrector to the proper position, but children in the growth stage have small age and are subjected to long-term and multiple operations, and even adult patients feel very difficult and frustrated, and the children who are not adult are ill. Spinal aligners currently used in the growth phase, such as "Surgical management of early-onset scoliosis" by Tom PC Schlosser et al: indications and currently available techniques, wherein the TGR (Traditional growing rods) corrector is fixed at one end of the spine by two relatively telescopic rods, the back of the patient is scratched and opened by an operation opening mode according to the growth speed of the patient, a doctor can adjust the length of the two rods, and the patient usually has to open the knife once again every 6 weeks, so that the whole correction course has to undergo multiple operations, and the correction is a very painful physiological and psychological affliction for the patient.

MCGR (Magnetically controlled growing rods) the appliance improves the defect of frequent cutting of TGR, MCGR adopts the external magnetic induction mode of patient, changes the length of the appliance at two ends of the spine to respond to the growth of the patient, although the defect that TGR needs frequent cutting can be avoided, the growth of the patient is continuous, and the adjustment of MCGR still needs to be evaluated and operated by doctors every minute every second every day, so that the growth requirement of the patient every minute every second can not be satisfied in time, and the improvement is also necessary.

The inventor has made a research on the present invention, and finally, has disclosed a scoliosis correction device capable of automatically adjusting according to the growth of the spine.

The fixing seat comprises a seat body, a receiving cavity is concavely arranged at the top end of the seat body, the receiving cavity transversely penetrates through the seat body, and a fixing element is arranged at the bottom of the fixing seat and is used for being fixed on one of vertebral bodies of the vertebra of a patient;

The guide tube comprises a through hole which penetrates through the guide tube, and the guide tube is arranged in the receiving hole of the fixed seat; and

The first correcting rod passes through the through hole, so that the guide tube can slide relatively along the first correcting rod, wherein the first correcting rod can be elastically bent, and the first correcting rod is elastically restored to the original shape after the external force is removed.

2. The spinal lateral curvature correction component as recited in claim 1, wherein the cavity wall of the receiving cavity forms a screw hole section for screwing the positioning plug to limit the guiding tube in the receiving cavity, and a protruding plug is protruded at the bottom end of the positioning plug to correspondingly extend into the hole of the guiding tube and to press the first correction rod in the guiding tube.

3. The spinal lateral curvature correction device according to claim 1, wherein a second seat is further connected to one side of the seat, the second seat has a through hole penetrating therethrough for receiving a second correction rod therein, and the second correction rod is slidably moved in the through hole or screwed into the through hole.

4. The spinal lateral curvature correction assembly as recited in claim 1, wherein a second seat is further connected to one side of the seat, the second seat has a recess downwardly from a top end thereof for receiving a second correction rod therein, and the second correction rod is slidably movable relative to the recess.

5. The vertebral lateral curvature correction device of claim 1, wherein a lateral seat is further connected to one side of the seat, a second receiving cavity is concavely formed in a top end of the lateral seat, the fixing element is disposed at a bottom end of the second receiving cavity, and the second receiving cavity is screwed with a tightening plug to limit the second correction rod or the second guide tube.

6. The spinal lateral curvature correction device of claim 5, further comprising a seat for receiving a bottom portion of the second rod or the second guide tube and straddling over the fixation element, the seat being configured to compress and secure the fixation element when the compression plug is compressed against a top end of the seat.

7. The spinal lateral curvature correction component of claim 1, further comprising a connector with a first end locked to the guide tube and a second end having a through hole for receiving a second correction rod, wherein the second correction rod is slidably received in the through hole or is fixed in the through hole.

8. The spinal lateral curvature correction assembly of claim 1, wherein the first end of the guide tube defines a convex end and the second end of the guide tube defines a concave end.

9. The spinal lateral curvature correction device of claim 1, wherein the first end of the guide tube forms a first tube segment, the second end of the guide tube forms the through hole, and the first tube segments of two adjacent guide tubes are in sliding engagement with the through hole.

10. The spinal lateral curvature correction device of claim 9, wherein the guide tube has a plurality of detents resiliently protruding through the through hole and a plurality of ratchet teeth or locating pockets formed in the first tube section of the guide tube.
