Problems solved by technology

Some cervical spondylotic myelopathy requires spinal canal enlargement surgery decompression treatment. Posterior cervical single-door laminoplasty is one of the most effective methods for the treatment of cervical spondylotic myelopathy, but the traditional internal fixation method is prone to opening and closing the door , resulting in restenosis of the cervical spinal canal and "axial symptoms", affecting the curative effect of surgery
With the development of science and technology, miniature titanium plates have appeared on the market, but this technology can only fix the vertebral body on the side of the door, because the cervical vertebral body of the diseased part needs to be incised on one side and the groove on the other side should be incised first. For micro-rotation, differences

Embodiment

[0032] Such as Figure 1-4 As shown, the posterior cervical plate provided by this embodiment includes: a first cervical plate 2, a second cervical plate 3 and a U-shaped connector 1 with adjustable opening size, the first cervical plate 2 and the second cervical plate The cervical vertebral plates 3 are connected by the U-shaped connecting body 1; the first cervical vertebral plate 2 and the second cervical vertebral plate 3 are both configured as bent cervical vertebral plates.

[0033] It should be noted that in the traditional posterior board operation, it is necessary to establish a channel on the spinous process 15 so that the titanium cable / suture can pass through the fixed spinous process 15; however, this posterior cervical board avoids the establishment of a channel on the spinous process 15 and avoids The knotting of ropes such as metals can irritate the skin, and at the same time, it can have a good fixing effect on the spinous process 15 and the like.

Abstract

The invention relates to the technical field of medical instruments, in particular to a posterior cervical plate, which comprises a first cervical plate, a second cervical plate and a U-shaped connecting body with an opening the size of which is adjustable, wherein the first cervical plate and the second cervical plate are connected through the U-shaped connecting body; the first cervical plate and the second cervical plate are all arranged as a bent cervical plate. According to the invention, the treatment of the spinal cervical diseases can be better achieved, and the pain brought by the operation to a patient can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a posterior cervical plate. Background technique [0002] Cervical spondylotic myelopathy is one of spinal cord compression diseases, severe cases can be disabled, accounting for 10%-15% of all cervical spondylosis. Some cervical spondylotic myelopathy requires spinal canal enlargement surgery decompression treatment. Posterior cervical single-door laminoplasty is one of the most effective methods for the treatment of cervical spondylotic myelopathy, but the traditional internal fixation method is prone to opening and closing the door , resulting in restenosis of the cervical spinal canal and "axial symptoms", affecting the efficacy of surgery. With the development of science and technology, miniature titanium plates have appeared on the market, but this technology can only fix the vertebral body on the side of the door, because the cervical vertebral body of the dis...
