Posterior cervical plate

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...

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 in the doctor's personal habits, surgical methods, surgical strength and other factors may cause fracture of the vertebral body on the side of the portal axis. Traditional open-door surgery requires complete or partial resection of the cervical spinous process and the attached ligaments. Afterwards, it is easy to cause symptoms such as cervical spine instability and decreased range of motion of the cervical spine; or it is necessary to add steel wires, sutures and other implants for fixation, which will increase stimulation or damage to surrounding tissues and nerves; at the same time, neck activities will also lead to Wire cables and sutures have a cutting effect on the surrounding soft tissue, increasing the risk of postoperative infection and inflammation, and bringing pain to the patient
