Description

An AI-powered cervical disc that records pressure and motion

technical field

The invention relates to the technical field of medical devices, in particular to an artificial intelligence cervical intervertebral disc that can record pressure and motion

Background technique

In order to adapt to visual, auditory and olfactory stimuli, the cervical spine needs greater and sharper mobility. Therefore, the range of motion of the cervical spine is much larger than that of the thoracic and lumbar spine, such as forward flexion and rear extension, left and right lateral flexion, left and right rotation, and the circular movement formed by the above-mentioned movements.

The cervical intervertebral disc is located between the two vertebral bodies of the cervical spine and is composed of a cartilage plate, annulus fibrosus, and nucleus pulposus. There are cartilage plates on the upper and lower sides, which are hyaline cartilage covering the vertebral body and the bony surface in the middle of the lower epiphyseal ring. The upper and lower cartilage plates seal the nucleus pulposus together with the annulus fibrosus. The annulus fibrosus is composed of fibrocartilage of collagen fiber bundles and is located around the nucleus pulposus. The fiber bundles of the annulus fibrosus intersect obliquely and overlap each other, making the annulus fibrosus a solid tissue that can withstand large bending and torsional loads. For patients after cervical discectomy, artificial cervical discs are needed.

However, after the artificial cervical intervertebral disc is surgically implanted, the doctor can only periodically (for example, 1 week, 3 months, 6 months, 1 year, 2 years, etc.) review the cervical spine X-ray, CT, etc. The function evaluation of the artificial intervertebral disc in the body, this state evaluation is actually the evaluation of the state at a certain point in time, and cannot reflect the overall dynamic state of the artificial intervertebral disc in various postures, actions, and states. Moreover, the radiation produced by the current review methods such as X and CT is unavoidable when patients are reviewed.
