Abstract

The invention provides a spinal canal expanding device. The device comprises a fixing part, which comprises a mounting plate and swinging plates positioned at two ends of the mounting plate; a plurality of supporting plates movably arranged on the mounting plate, the plurality of supporting plates are correspondingly arranged, and the plurality of supporting plates are provided with supporting positions which are far away from each other and mounting positions which are close to each other; a locking piece connected between the swinging plate and the supporting plate; and expansion pieces arranged among the plurality of supporting plates. According to the device, a problem that thorough decompression cannot be effectively achieved through a traditional operation mode in the related technology is effectively solved.

Description

technical field [0001] The invention relates to the technical field of spinal canal enlargement, in particular to a spinal canal enlargement device. Background technique [0002] Cervical spondylotic myelopathy is a more serious type of degenerative cervical spondylosis. Due to the compression of the cervical cord or nerve roots, it often causes neurological symptoms such as paresthesia or paralysis of the limbs, and the disease develops progressively. Surgical intervention to relieve spinal cord or nerve root compression, prevent further deterioration of neurological function, and improve the patient's quality of life. [0003] Cervical spinal canal enlargement is a traditional surgical method for posterior decompression of cervical spondylosis. The operation needs to remove the lamina through the posterior approach, and then expand the area of ​​the spinal canal to achieve the purpose of decompression. However, this surgical method has the following disadvantages: after t...
