Omega-shaped artificial cervical intervertebral disc implant with diamond-shaped bilateral stopping pawls

Abstract

The invention relates to an Omega-shaped artificial cervical intervertebral disc implant with diamond-shaped bilateral stopping pawls. The Omega-shaped artificial cervical intervertebral disc implant comprises a body and is characterized in that the body adopts an Omega-shaped non-contacting elastic structure of which an upper end plate and a lower end plate are integrated; diamond-shaped bilateral stopping pawls are symmetrically arranged on the outer surfaces of the upper end plate and the lower end plate of the body respectively; the lower end plate of the body is 10 to 16 mm in length, and the upper end plate is 1 mm shorter than the lower end plate; the distance between the upper end plate and the lower end plate of the body is 2 to 3.5 mm; and the thickness of a bending section at the rear end of the body is 0.6 to 1.2 mm. After the implant provided by the invention is implanted, the space is stable, an elastic force is used for supporting and no bolt is required for fixing, so that direct friction or abrasion between the upper end plate and the lower end plate is avoided fundamentally, and the performance requirements for long service life and fatigue resistance of the implant can be met. The invention achieves the purpose that the range of motion of forward bending and the range of motion of sideward bending of the cervical vertebrae segment of a patient receiving an operation can reach 30% to 60% of that of normal cervical vertebrae, and the range of motion of backward extending can reach 70% to 90% of that of normal cervical vertebrae.

AI Technical Summary

Benefits of technology

This patented technology provides technical benefits over existing methods that have been developed previously but they still lack certain featureings such as stabilizing spaces during surgery or eliminating any external components like bolts. These improvements also preserve important functional aspects of these devices while reducing their size.

Problems solved by technology

This patents discusses three technical methods described above for replacing damaged parts (interspinel) between natural ones called posterior lumbar arteries and targeted areas like those involved during orthocerumatic hip procedures. However, current techniques involve complex processes requiring multiple surgeries, leading to compliance issues and potential revision options. Therefore, the objective of this patented innovations involves developing a simpler method without sacrificing functionality.
