Artificial intelligent cervical zygapophyseal joint prosthesis

Abstract

The invention relates to an artificial intelligent cervical zygapophyseal joint prosthesis. The prosthesis comprises an upper metal plate, an inner support body, an outer ring, a lower metal plate, atleast one pressure sensor, a wireless communication module and a miniature battery. The pressure sensor is electrically connected with the wireless communication module, the inner support body and the outer ring are made of polymer materials, and the pressure sensor, the wireless communication module and the miniature battery are all arranged in the inner support body. The two ends of the outer ring are respectively connected with the upper metal plate and the lower metal plate, the inner support body is located inside the outer ring, and the two ends of the inner support body are respectively rotatably connected with the upper metal plate and the lower metal plate. The prosthesis can achieve the stability of the cervical zygapophyseal joint and retain a certain degree of motion to cooperate with the stability and movement of an entire vertebral body so that a degenerative or dysfunctional zygapophyseal joint can be reconstructed and the real pressure change of the prosthesis in vivoafter surgery can be recorded in real time. The non-invasive and real-time monitoring of the function and status of the prosthesis is achieved to evaluate a patient's short-term and long-term risks after replacement surgery and to instruct rehabilitation training.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an artificial intelligence cervical facet joint prosthesis. Background technique [0002] Cervical facet joints, also known as intervertebral facet joints, belong to a synovial joint composed of the upper and lower facet joints of adjacent cervical vertebrae. The facet joints form an angle of about 40-45° with the horizontal plane. The articular surface is smooth and covered with hyaline cartilage. The joint capsule is attached to the edge of the articular cartilage. It is thin and loose, and has certain stability, flexion, extension and rotation within a certain range. The arrangement of the cervical facet joints is conducive to the flexion and extension of the cervical spine, but it is relatively unstable and prone to injury. The anatomical features of facet joints are the anatomical basis for their degeneration. [0003] Anatomical and biomechanical studies in recent...

AI Technical Summary

Problems solved by technology

After traditional posterior facet joint resection, the anatomical structure of the cervical facet joint is destroyed, and its stability and activity function are lost, which means that the overall stability of the cervical spine is destroyed
