Abstract

The invention discloses a tapping type zero-incisure cervical fusion cage which comprises a supporter part and a fixing screw. The whole supporter part is of a circular-truncated-cone-shaped structure. A tapping type thread is formed in the side face wall of the supporter part. The supporter part is provided with a bone grafting groove and the fixing screw. The tapping type zero-incisure cervicalfusion cage has a good self-stabilizing structure, the auxiliary fixing of an anterior titanium plate is avoided, the influences on cervical soft tissue are low, and the tapping type zero-incisure cervical fusion cage has the advantages of being easy to assemble, convenient to implant, capable of forming a small wound, low in postoperative complication occurrence rate and the like.

Description

technical field [0001] The invention belongs to the technical field of medical prosthesis manufacturing, in particular to a self-tapping zero-profile cervical intervertebral fusion device. Background technique [0002] With the transformation of human life and work style, the incidence of cervical spondylosis is increasing year by year, and it has become a common and frequently-occurring disease that endangers human health. The disease often causes dizziness, numbness of limbs, weakness, nausea and other uncomfortable symptoms, and severe cases can lead to high paraplegia, which brings a heavy economic burden to society and families. [0003] The above-mentioned diseases often require surgical treatment when they develop to a certain stage. At present, the classic surgical methods include anterior cervical discectomy and fusion (ACDF), anterior cervical subtotal corpectomy and fusion (anterior cervical corpectomy and fusion, ACCF), and posterior cervical spinal canal expans...
