Problems solved by technology

However, in the current spinal posterior approach, there is no special fixing material and device suitable for maintaining the opening position of the cervical lamina and preventing the door from closing again.
Clinically, steel wires or wires are commonly used for binding and fixing. After fixing, it is very unreliable, which will affect the postoperative effect or cause surgical complications.

Embodiment Construction

[0022] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various changes in different embodiments without departing from the scope of the present invention, and that the description and drawings therein are illustrative in nature and not limiting. this invention.

[0023] Such as figure 1 and figure 2 As shown, the present invention includes a main body 1. The main body 1 is made of pure titanium, or it can also be made of titanium alloy or plastic biocompatible polymer material, so as to achieve intraoperative bending according to the specific position of the lamina. The lower surface of the body 1 can be a plane or an irregular surface adapted to the anatomical structure of the human body, the lower surface is attached to the lamina of the human spine, and the upper surface of the body 1 is a plane or an irregular plan...

Abstract

The invention provides a posterior cervical single-door bone plate which comprises a body, a first end, a second end and a middle portion. The middle portion is connected with the first end and the second end, the first end and the second end are respectively provided with a through hole used for installing a fixing element, and the middle portion is provided with a long through hole used for containing a screw in the length direction. By means of the posterior cervical single-door bone plate, an open vertebral plate in laminoplasty can be fixed and is prevented from being closed again. The posterior cervical single-door bone plate is simple in structure and convenient and quick to operate.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a bone plate used for cervical posterior fixation. Background technique [0002] Clinically, various cervical diseases such as spinal stenosis, cervical disc herniation, and cervical spinal cord injury often require posterior decompression. The conventional method of decompression surgery is to perform laminectomy for decompression, and use rongeurs to bite off the spinous process and lamina to expose the spinal canal of the corresponding segment. Internal fixation with posterior plating material. However, this operation method makes the patient's cervical spine activity function lost, and often causes intractable pain after operation, and the activity is limited, which affects the curative effect of the operation. If the bone plate is not fixed after the decompression of the lamina, it may cause postoperative cervical instability and kyphosis. [0003] In recent years, "sin...
