Self-locking integrated anterior cervical board

Abstract

The invention discloses a self-locking integrated anterior cervical board, and belongs to the technical field of medical apparatuses. The self-locking integrated anterior cervical board comprises an anterior cervical board body, a clasp and a universal screw. The anterior cervical board body is provided with a locking hole, the hole wall of the locking hole is a spherical surface provided with first sawteeth. The clasp has an opening, the outer wall of the clasp is a second spherical surface provided with sawteeth, the clasp is mounted in the locking hole via elastic deformation, and the first spherical surface and the second spherical surface are mutually embedded via the first sawteeth and the second sawteeth. The inner wall of the clasp is provided with a fist thread. The side wall of the head of the universal screw is a conical surface, the side wall of the head is provided with a second thread matching the first thread, the head of the universal screw is screwed into the clasp through cooperation of the first thread and the second thread. The self-locking integrated anterior cervical board is good in integration, the anterior cervical board will not loosen and fall off, the anterior cervical board can be locked twice through retreating a nail. The self-locking integrated anterior cervical board is easy to operate and safe in operation, and by adopting the self-locking integrated anterior cervical board, an operation is short in time, stimulation to esophagus and foreign body sensation can be reduced after the operation.

Description

technical field [0001] The invention discloses a self-locking integrated cervical spine anterior plate, which belongs to the technical field of medical devices. Background technique [0002] In the process of rapid economic development in the contemporary era, the incidence of cervical spondylosis is very high. In the occurrence and development of cervical spondylosis, chronic strain, trauma, congenital dysplasia or defects may all become the pathogenic factors of cervical spondylosis. These lesions cause deformation and narrowing of the cervical spinal canal or intervertebral foramen, stimulate and compress the cervical spinal cord and nerve roots, and cause corresponding clinical symptoms. Drug therapy can not fundamentally treat the disease, and surgical treatment becomes inevitable. [0003] At present, the anterior cervical plate on the market mainly has the following disadvantages, such as: the nail plate (the body of the anterior cervical plate) is easy to fall...

Drug therapy cannot treat fundamentally, and surgical treatment becomes inevitable

[0003] At present, the anterior cervical plate on the market mainly has the following disadvantages, such as: the nail plate (the body of the anterior cervical plate) is easy to fall off and loosen; it cannot be locked twice, which increases the operation time; The notch of the nail plate is high and narrow, which affects the life of the patient
