Description

Technical Field

[0001] The invention relates to a spinous process suspension type spinal correction device, in particular to a spinal correction device which can be automatically adjusted as the patient grows. Background Art

[0002] Scoliosis is caused by long-term poor posture, while others are congenital scoliosis. If scoliosis occurs in adults (when bones no longer grow), good treatment results can be achieved through surgery for correction and fusion fixation. However, if scoliosis occurs in the growth stage of children or teenagers, the patient's spine will continue to grow during the growth stage, so the correction method and device performed by fusion fixation surgery are not applicable.

[0003] For patients with scoliosis in the growth stage, the current medical advice is to perform surgical correction only when the scoliosis exceeds 45 degrees or has severely compressed the heart and lung function. The scoliosis correctors currently suitable for this stage must be used for multiple surgeries in accordance with the patient's growth rate to adjust the corrector to the appropriate position. However, children in the growth stage are still young and have to endure long-term and multiple surgeries. Even adult patients will find it very unbearable and frustrating, let alone underage children. Currently, spinal braces are used in the growth stage, such as the article "Surgical management of early-onset scoliosis: indications and currently available techniques" published by Tom PC Schlosser et al. The TGR (Traditional growing rods) brace is composed of two relatively retractable rods, each fixed at one end of the spine. According to the patient's growth rate, the doctor can adjust the length of the two rods by cutting open the patient's back and opening the brace through surgery. Usually, the patient must undergo another surgery every 6 weeks, so that the entire correction course must undergo multiple surgeries, which is an extremely painful physical and psychological torture for the patient.

[0004] MCGR (Magnetically controlled growing rods) correctors improve the disadvantage of TGR's frequent surgeries. MCGR uses magnetic induction outside the patient's body to change the length of the correctors installed at both ends of the spine to respond to the patient's growth. Although it can avoid the disadvantage of TGR's frequent surgeries, the patient's growth is continuous, growing every minute of every day. The adjustment of MCGR still requires doctor's evaluation and operation. Therefore, it cannot meet the patient's growth needs every minute of every second in a timely manner, and it is obviously necessary to improve it.

[0005] Therefore, the inventor and applicant of this case disclosed a scoliosis correction component that can automatically adjust with the growth of the spine, and submitted an invention patent application to the Intellectual Property Office of Taiwan, China. The invention patent has been approved and is on file with the announcement number I924944. The case discloses a scoliosis correction component that can automatically adjust with the growth of the spine, including: a fixed seat, which includes a seat body, a receiving hole is recessed at the top of the seat body, the receiving hole passes through the seat body horizontally, and a fixing element is installed at the bottom of the fixed seat, the fixing element is used to be fixed on one of the vertebrae of the patient's spine; a guide tube, which includes a guide hole passing through, the guide tube is placed in the receiving hole of the fixed seat; and a first correction rod, which passes through the guide hole so that the guide tube can slide relatively along the first correction rod; wherein the first correction rod can be made of metal or non-metal material, the first correction rod is in the shape of a thin rod or a cable, can be elastically bent, and when the external force is removed, the first correction rod can elastically return to its original shape. In this way, when the distance between the vertebrae of the spine changes during the growth of the patient, the fixed seat fixed on the vertebrae will link the guide tube to slide relatively along the first correction rod, so as to automatically adjust according to the distance change between the vertebrae of the patient during the growth stage, thereby solving the shortcomings of the existing fusion corrector that cannot be adjusted or the current adjustable corrector that needs to be adjusted surgically every once in a while, thereby greatly reducing the patient's physical and psychological pain. A similar structure is also disclosed in US Patent US 11744618 B2.

[0006] No. 1924944 or US Pat. No. 11744618 B2 mentioned above, both adopt the existing pedicle screw structure, in which a socket is recessed on the seat of the pedicle screw, and a guide tube is fixed in the socket by a fixing element, so that the correction rod can be inserted into the guide tube and slide relatively. Therefore, during the operation, the guide tube must be installed. Since the patient who undergoes scoliosis correction must install the guide tube on many vertebrae, the above-mentioned scoliosis correction assembly not only shows the cumbersome installation steps, but also increases the time required for the operation, which will increase the surgical risk of the patient and show its disadvantages.

[0007] In addition, relevant research papers have pointed out that when pedicle screws are locked into the pedicles of the vertebral body, the growth plates in the pedicles may be affected, causing the bones to stop or slow down their growth. Therefore, when young children or adolescents in the growth stage use the above-mentioned existing scoliosis correction devices, there may be problems that affect their future growth, and there is a clear need for improvement.

[0008] In view of this, the inventor of the present invention has conducted further research and finally disclosed the spinous process suspension type spinal correction device shown in the present invention. Summary of the invention
