Embodiment Construction

[0017] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, so as to understand the essence of the present invention more clearly and intuitively.

[0018] In the accompanying drawings, the present invention provides a posterior cervical self-locking distraction fixer, which includes a support plate A1 and a support plate B2. One end of the support plate A1 is a rectangle, and the other end is an isosceles triangle. The support plate There is a chute 7 inside A1, and the inner wall of the chute 7 is provided with a ratchet 4. Correspondingly, one end of the support plate B2 is a rectangle, and the other end is an isosceles triangle. The ratchets that match the ratchets 4 on the inner wall of the chute 7 of the support plate A1, the ratchets 4 are right-angled triangles, and the tooth tips of the ratchets 4 of the support plate A1 face the rectangular structural end of the suppor...

Abstract

The invention discloses a cervical posterior approach self-locking strutting fixer, comprising a support plate A and a support plate B, wherein the tail end of the support plate A is an isosceles triangle, is provided with a barb, and is internally provided with a chute, the inner wall of the chute is provided with ratchet teeth, the tail end of the supporting plate B is an isosceles triangle, andis provided with a barb and ratchet teeth, the supporting plate B can be inserted into the chute of the supporting plate A, and the barbs can be matched with each other. This design is used for cervical posterior transforaminal approach, fully protecting a cervical posterior muscle spinous ligament complex, retaining important structures such as nuchal ligament, supraspinous ligament, interspinous ligament and ligamentum flavum. Cervical 3 to cervical 7 bilateral laminae are cut open by a piezosurgery, and then are fixed by the self-locking strutting fixer, thus maintaining the laminar liftedand refiguring a wider spinal canal, and closer to a cervical spine physiological structure after surgery, the reconstruction of the posterior neck structure is achieved in real sense, complicationsof a traditional cervical posterior approach surgery are reduced, the operation is simple in the surgery, and the efficiency and the safety of the surgery are improved.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to a posterior cervical self-locking distraction fixer. Background technique [0002] Currently, there are 3 surgical methods in clinical application of posterior cervical spine surgery. The first one is the expansion and decompression of the spinal canal, that is, the posterior median approach exposes the cervical lamina and resects the lamina from C3 to C7; the second is the single-door decompression of the expansion of the spinal canal, and the lamina on one side is completely cut off The contralateral lamina cuts the outer cortex; the third method is the double-door decompression of the spinal canal, in which the middle of the lamina is cut, and the outer cortex is resected near the articular process of the bilateral lamina. The above three surgical methods will damage the muscle spinous process ligament complex at the back of the neck to varying degrees, resulting in axial sy...
