A cervical disc instrument that includes a handle that defines a cavity therein, a trial head, and a blade. The trial head is removably coupled to the handle and configured for insertion into a disc space. The blade is disposed in the cavity of the handle and configured to cut a surface that at least partially defines the disc space when the trial head is located in the disc space.

The invention relates to the technical field of medical health technologies, in particular to a refined intervention system and method for cervical disc herniation of old people, and the system comprises a data collection module, a data analysis module, an intervention scheme making module and an intervention execution module. The data acquisition module is used for acquiring medical images, physiological indexes and symptom information; medical imaging equipment is adopted to obtain image data of the cervical vertebra of the elderly, and the form, position and protrusion degree of the cervical intervertebral disc and the compression condition of surrounding tissue are clearly displayed; physiological indexes of heart rate, blood pressure and oxyhemoglobin saturation of the elderly are collected in real time through a wearable device and a physiological monitoring instrument, and meanwhile, the motion range of the neck and muscle strength motion function data are recorded; the cervical vertebra condition is accurately evaluated according to the individual difference of the old people, fine intervention is achieved, the symptom of cervical disc herniation is effectively relieved, the complication risk is reduced, and the life self-care ability and life quality of the old people are improved.

The application relates to the technical field of artificial prostheses, and discloses an artificial cervical intervertebral disc based on a biological bionic structure, which comprises an upper endplate, a lower endplate and an elastic body core arranged between the upper endplate and the lower endplate; the elastic body core comprises an anterior annulus fibrosus, a nucleus pulposus and a posterior annulus fibrosus; the anterior annulus fibrosus is composed of an outer fiber layer, an intermediate transition layer and an inner fiber layer and anterior collagen fibers arranged between the fiber layers; the application reproduces the structural composition and configuration of a biological cervical intervertebral disc, adopts differentiated arrangement of the anterior and posterior annulus fibrosus, gradient inclination angle design of the collagen fibers, elastic deformation characteristics of the nucleus pulposus and material combination with different elastic moduli, so that the artificial cervical intervertebral disc can be more naturally matched with the physiological movement mode of the vertebrae after being implanted; and the irregular endplate is more suitable for the cervical uncinate joint and is adapted to complex movement in multiple directions.

A method of single position 360 degree cervical fusion includes positioning a patient in a lateral position on an operating table, orienting and maintaining the patient's spine at a desired sagittal plane alignment, performing anterior cervical disc fusion (ACDF), reorienting and maintaining the patient's head to facilitate posterior approach, and performing posterior fixation. Devices and systems configured to facilitate performing a single-position 360-degree cervical fusion method are also provided.
