Abstract

The invention relates to a lower cervical anterior distraction reduction device, which comprises two hinged handles, namely a first handle (1) and a second handle (2). Splaying plier jaws are respectively arranged at the front end of each handle. The two handles (1) and (2) and the splaying plier jaws on the two handles (1) and (2) are positioned on the same side edge. An adjusting toothed bar (7) is riveted at the end part of the first handle (1). A groove (2d) and corresponding teeth connected with the adjusting toothed bar (7) are arranged at the end of the second handle (2). The inner sides of the two handles (1, 2) are respectively provided with a first spring sheet (4) and a second spring sheet (5) correspondingly. The device is characterized in that the fixed end of the first spring sheet (4) is cone-shaped and the free end thereof is provided with a small steel ball (3). The fixed end of the second spring sheet (5) is provided with a positioning hook (5a) and the free end thereof is provided with a spoon-shaped ball seat (5b). The steel ball (3) and the spoon-shaped ball seat (5b) are in contact to form a spring device. The lower cervical anterior distraction reduction device has the advantages of simple structure and convenient use; the operative efficiency can be remarkably improved by using the reduction device in the lower cervical zygopophysis interlocking reduction; and the difficulty of surgery operation and the incidence rate of complicating diseases are both reduced and the operative wound of patients is relieved.

Description

technical field [0001] The invention relates to a medical device for lower cervical vertebra reduction operation, in particular to an anterior distraction reduction device for the interlocking of the articular processes of the lower cervical vertebra. Background technique [0002] In recent years, the incidence of cervical trauma has been increasing year by year. Cervical facet dislocation and interlocking account for 50% of cervical trauma. Unilateral or bilateral cervical facet interlocking is the result of cervical spine flexion, lateral flexion or rotational violence. The destruction of the column structure, the stability of the cervical spine, the shape of the spinal canal, and the spinal cord are damaged to varying degrees. Early reduction and decompression and reconstruction of the stability of the cervical spine are of great significance to alleviate secondary spinal cord injuries and promote the recovery of spinal cord function. At present, the commonly used treatme...
