Embodiment Construction
[0011] Refer to attached figure 1 , the internal fixation and binding device of the spinous process comprises a fixing rod 2 and a binding belt 3 . There are two fixing rods, which are bent into waves. The wavy shape of the fixing rod conforms to the shape of the spinous process of the human body. The two ends of the fixing rod 2 are provided with anti-off hooks 1, which can prevent the binding band 3 from slipping off. The fixing rods 2 are respectively tied to the wavy troughs of the fixing rods 2 through several binding straps 3 to connect the fixing rods 2 together.

The invention relates to an internal fixation binding device of processus spinosus, in particular to an internal fixation device used for cervical vertebrae back route structural damage and inapparent centrum damage, which can also be used as an auxiliary fixing device of other internal fixation techniques. The internal fixation binding device of processus spinosus comprises two fixation bars and a plurality of binding belts, wherein the fixation bars are bent into wave shapes, are respectively bound at the wave-shaped wave valleys of the fixation bars by the binding belts and are connected together. The wave shape formed by bending the fixation bars conforms to the shape of the processus spinosus of a human body. Both ends of the fixation bars are provided with falling-off prevention bent hooks.
Description
technical field [0001] The spinous process internal fixation and bundling device of the present invention is an internal fixation device that is structurally damaged in the posterior approach of the cervical spine and the damage of the vertebral body is not obvious, and can also be used as an auxiliary fixation device for other internal fixation techniques. Background technique [0002] At present, with the development of surgical methods, many spinal internal fixation devices are developed on the basis of spinous process internal fixation devices. The first to appear is the spinous process internal fixation and binding device, which has been used clinically for many years. For example: interspinous steel wire binding, triple steel wire binding and articular process steel wire binding. Simple steel wire binding is used for fixation. After the operation, the steel wire is easy to break, and the rotation resistance is poor. It cannot be used for lamina fractures and cannot ma...
