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 utility model belongs to the technical field of medicine pillows for treating rhinitis, and particularly relates to a bacteriostatic and anti-mite medicine pillow for treating rhinitis, which comprises a support plate, a charging groove arranged in the support plate, a plurality of round holes arranged on the peripheral side of the support plate, a sponge pad sleeved on the support plate, a baffle arranged on one side of the support plate, and slots symmetrically arranged on one side of the baffle close to the support plate. Inserting blocks are fixedly mounted on one side of the supporting plate and located in the two inserting grooves correspondingly; the limiting assembly is located in the baffle and used for limiting one of the inserting blocks; according to the utility model, the comfort of the head of a person can be ensured, the supporting performance is better, the problems of muscle strain of cervical vertebra, straightening of physiological curvature of cervical vertebra, even protrusion of cervical intervertebral disc and the like can be avoided when the person uses the pillow for a long time, the person can conveniently detach the sponge cushion, and the sponge cushion can be cleaned and acarid can be removed in time; and bacteria and mites are prevented from being attached to the head of a person.

The invention 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 end plate, a lower end plate and an elastomer core arranged between the upper end plate and the lower end plate, the elastomer core comprises a front annulus fibrosus, a nucleus pulposus and a rear annulus fibrosus; the front fiber ring is composed of an outer side fiber layer, a middle transition layer, an inner side fiber layer and front collagenous fibers located among the fiber layers. The artificial cervical intervertebral disc can be more naturally matched with the physiological movement mode of vertebrae after being implanted by adopting differentiated arrangement of front and rear fibrous rings, gradient dip angle design of collagenous fibers, elastic deformation characteristics of nucleus pulposus and material combination with different elastic moduli; the irregular-shaped end plate is more attached to the cervical vertebra hook process joint and adapts to multi-direction complex movement.

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.
