Technical Field
The utility model relates to the technical field of medical equipment, in particular to a fixing steel plate for cervical vertebra and posterior cervical muscle reattachment.
Background
Cervical posterior longitudinal ligament ossification is a disease of cervical posterior longitudinal ligament ectopic ossification which leads to spinal cord and nerve root compression, and causes limb sensory and movement disorder and sphincter dysfunction. For patients with multi-segment cervical posterior longitudinal ligament ossification extending to C2 and above, the C2 vertebral canal needs to be expanded and decompressed, and the atlas posterior arch is resected. The muscular ligament complex at the back of the neck is usually damaged in the posterior cervical surgery process, so that the physiological curvature of the cervical vertebra is lost, the sagittal balance of the cervical vertebra is destroyed, and the symptoms of head lifting weakness can occur after the operation of a patient, and the head lifting can be usually carried out by the assistance of hands. Therefore, there is a need for a fixation steel plate for cervical vertebra cervical muscle reattachment, which can realize the reconstruction of cervical muscle, relieve the clinical symptoms of spinal cord and nerve compression, and reconstruct the cervical vertebra stability.

The technical scheme adopted for solving the technical problems is as follows:
the utility model provides a cervical vertebra neck posterior muscle is heavy to be attached with fixed steel sheet, including the steel sheet body and set up the connecting plate with steel sheet body both ends, the steel sheet body is the arc that accords with two spinous processes physiological curve of human neck and buckles, the interval is equipped with a plurality of muscle fixed orifices on the steel sheet body, steel sheet body's both ends tend to the level, be provided with the connecting plate along the extending direction at steel sheet body both ends, be provided with pedicle screw mounting hole on the connecting plate, during the use, be convenient for install pedicle screw on the connecting plate, fix the position of steel sheet body in place, then stitch the muscle on the muscle fixed orifices, improve operating efficiency, realize muscle rebuilding behind the neck, alleviate spinal cord, nerve oppression's clinical symptom, rebuild cervical vertebra stability, eliminate patient's postoperative head up weakness's symptom.
Further, a nail rod is arranged in a nail seat of the pedicle screw, the nail seat of the pedicle screw is positioned below the connecting plate, a plug screw of the pedicle screw penetrates through a pedicle screw mounting hole to be connected with the nail seat and is abutted against the nail rod, and a plug screw head of the pedicle screw is abutted against the upper side of the connecting plate to ensure the connection stability of the pedicle screw and the connecting plate.
Further, the pedicle screw mounting hole is a slotted hole, the length is larger than the outer diameter of the screw plug rod, and the width is matched with the outer diameter of the screw plug rod, so that the position of the pedicle screw can be conveniently adjusted according to the cervical vertebra shape of a patient.
Further, the width of connecting plate is greater than the width of steel sheet body, improves pedicle screw connection stability.
Furthermore, the connecting plate is in a smooth ellipse shape, so that muscle tissues are prevented from being damaged.
The beneficial effects of the utility model are as follows: compared with the prior art, the fixing steel plate for cervical vertebra posterior muscle reattachment has the following advantages: the pedicle screw is convenient to install on the connecting plate, the position of the steel plate body is fixed in place, then the muscle is sutured on the muscle fixing hole, the operation efficiency is improved, the reconstruction of the muscle after the neck is realized, the clinical symptoms of spinal cord and nerve compression are relieved, the stability of the cervical vertebra is reconstructed, and the symptoms of head lifting weakness after the operation of a patient are eliminated.
