Embodiment Construction
[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0027] Cervical vertebral fractures in patients are often accompanied by bilateral or unilateral facet joint dislocation noose, and the effect of cervical traction and reduction on patients before operation is not obvious, and the risk is extremely high, especially for patients with incomplete paralysis. In the prior art, surgery generally needs to be done first Anterior discectomy for decompression of the spinal canal, turning over during the operation, and th...

The invention discloses a cervical dislocation expansion compression reductor. The cervical dislocation expansion compression reductor comprises cervical spine expansion compression devices (1) and acentral support device (2), the two cervical spine expansion compression devices (1) are symmetrically arranged with the central support device (2) as a center, and the cervical spine expansion compression devices (1) on two sides are connected with the central support device (2) in a slide manner. The cervical dislocation expansion compression reductor can avoid excessive turning-over of a patient for posture during an operation and carrying-out of a posterior reduction operation, reduce the injury to the spinal cord of the patient, and avoid unnecessary operations.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and relates to a distraction and pressurization resetter for cervical vertebra dislocation. Background technique [0002] Clinically, in spine surgery, for patients with cervical vertebral fractures with dislocation of posterior facet joints and noose, it is necessary to remove the cervical intervertebral disc during anterior cervical surgery first, and then place a cervical spreader, which only serves to open the cervical intervertebral space. For patients with cervical spine fractures with posterior facet joint dislocation and noose, there is no reduction effect. Contents of the invention [0003] The present invention provides a cervical dislocation distraction and pressurization resetter, in order to solve the bilateral or unilateral articular facet joint dislocation noose operation behind the cervical vertebra fracture, only the anterior discectomy and decompression of the spinal c...
