Anterior cervical approach self-fixation artificial centrum

Abstract

The invention discloses an anterior cervical approach self-fixation artificial centrum and belongs to the technical field of medical centrum manufacturing. The anterior cervical approach self-fixationartificial centrum is composed of an integrated centrum part and is mainly characterized by comprising an upper-end cambered surface, a lower-end oblique plane, an end face sawtooth structure, an endface micro-hole structure, a side wall rhombus hole, a back wall micro-hole structure, a front wall cambered surface structure, a back wall cambered surface structure and a screw hole structure for front wall self-fixing. A traditional anterior cervical approach titanium plate is removed on the premise that the stability of postoperative spine segments is ensured, the complexity degree of sub-total ectomy fusion of an anterior cervical approach cervical vertebra body is effectively reduced, the surgical time is shortened, the bleeding during surgery is decreased, a biomechanical conduction mode of an anterior cervical approach implantation instrument is optimized, and lots of complications caused by anterior cervical approach steel sheets are avoided. By adopting the above design, the anterior cervical approach self-fixation artificial centrum can effectively decrease lots of complications of a traditional titanium cage and improves prognosis of a patient suffering from the sub-totalectomy fusion of the anterior cervical approach cervical vertebra body.

Description

【Technical field】 [0001] The invention belongs to the technical field of medical prosthesis manufacturing, and relates to prosthesis transplantation after resection of cervical vertebral body and its adjacent intervertebral disc lesions. 【Background technique】 [0002] With the improvement of modern people's living standards and changes in lifestyle, the incidence of cervical disease is gradually increasing. Neck pain has become one of the main reasons for clinical visits, and the number of patients who visit a doctor due to cervical spine problems accounts for 1.5% of all diseases. Anterior cervical subtotal corpectomy and fusion is one of the most commonly used surgical methods in the treatment of cervical diseases, and is widely used in cervical degenerative diseases, trauma, tumors and other diseases. [0003] Currently, the most commonly used instrument in anterior cervical subtotal corpectomy and fusion is a titanium cage combined with an anterior cervical plate. The...

Problems solved by technology

However, there are still many disadvantages in this method: the installation of the anterior plate makes the operation complicated, prolongs the operation time, and increases the amount of bleeding; Adjacent segmental degenerative lesions; the traditional titanium cage is a simple cylindrical structure, and the two ends of the cage need to be trimmed based on the experience of the surgeon. After trimming, the end face of the titanium cage cannot fit the endplate, and the contact area is small and there are sharp cuts Protrusion, which eventually leads to the destruction of the endplate structure and the sinking of the titanium cage, which destroys the stability of the cervical spine after surgery

The above complications will seriously affect the postoperative rehabilitation and life safety of patients, and urgently need to be resolved

[0004] At present, there is no effective and simple method or technology to solve the problems caused by the above-mentioned anterior cervical plate
