Problems solved by technology

During the follow-up of clinical application, it was found that the screws implanted in the lateral mass of the titanium plate were prone to loosening and falling off, resulting in the failure of surgical fixation and fusion; the titanium plate did not support and maintain the stability of the lamina insufficiently, resulting in the inability to maintain the cervical vertebral body of this segment after surgery. normal function

Abstract

The invention discloses a titanium plate for laminoplasty. The titanium plate comprises a titanium plate main body, one end of the titanium plate main body is fixed at a vertebral plate notch break end, one end of the titanium plate main body is a clamping end, an upper vertebral plate clamp and a lower vertebral plate clamp are arranged on the clamping end, and clamp the vertebral plate notch break end clamp therebetween; the titanium plate lateral mass at the other end of the titanium plate main body is fixedly connected with a cervical vertebra lateral mass; screw holes on the titanium plate lateral mass are in diagonal distribution along the anatomical characteristics of the cervical vertebra lateral mass; the upper vertebral plate clamp and the lower vertebral plate clamp of the clamping end form an opened included angle; a stopper is arranged at the near end of the titanium plate lateral mass to form a clamping structure. The titanium plate disclosed by the invention can reduce the risks that the lateral mass screws are in loosening or falling off, and the fixation stability of the titanium plate is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a titanium plate used for laminoplasty. Background technique [0002] In the process of rapid economic development in the contemporary era, the incidence of cervical spondylosis is very high. When the cervical spine is damaged, the spinal cord in the cervical spine may be damaged, and the damaged spinal cord may compress the cervical nerves, causing discomfort, pain and other symptoms for patients. In clinical surgical treatment, the skin and deep tissue are usually incised to expose the spinous process, bilateral lamina, lateral articular process, laminectomy, fixation and fusion after resection, and incision closure. In the current technology, laminectomy mainly Including: total laminectomy, extended laminectomy, unilateral laminectomy. The former two methods belong to the removal of the lamina, which has a high degree of damage to the stability of the post...
