Description

Technical Field

[0001] The utility model relates to the technical field of titanium mesh, in particular to an integrated anatomical cervical titanium mesh system. Background Art

[0002] Anterior cervical corpectomy with decompression, bone grafting, and internal fixation is becoming increasingly popular. It effectively reduces pressure from the anterior approach while restoring cervical curvature, while avoiding the damage to the neck muscles associated with posterior surgery. Anterior cervical titanium alloy plates, mesh, and screw systems are widely used in anterior cervical corpectomy.

[0003] According to the disclosed integrated anatomical cervical titanium mesh system (authorization announcement number: CN211409543U), "the integrated anatomical cervical titanium mesh system includes a cylindrical titanium mesh, a head end gasket and a tail end gasket; the bottom of the head end gasket is connected to the top of the cylindrical titanium mesh as a whole; the bottom of the cylindrical titanium mesh and the tail end gasket are connected to each other through a hook, a slot and a threaded screw; the titanium mesh and the gasket are implanted together after installation, eliminating the step of installing the steel plate and simplifying the surgical operation; the top of the head end gasket is an arched annular surface with a certain curvature, and the arched annular surface is consistent with the inward concave curvature of the lower end plate of the cervical vertebral body, which can better fit with the cervical vertebral body and increase the contact area, which can not only enhance the contact between the bone graft particles and the bone surface of the cervical vertebral body, but also facilitate fusion. At the same time, better fit and larger contact area are conducive to dispersing stress, reducing the pressure on the contact surface with the cervical vertebral body endplate, and preventing the titanium mesh from damaging the lower endplate of the adjacent vertebra at the head end."

[0004] Existing titanium mesh structures are prone to exposing sharp parts after cutting, which can cause harm to the human body. Long-term wear of the titanium mesh can also lead to deformation, making subsequent secondary surgery inconvenient for maintenance and removal. Therefore, an improved integrated anatomical cervical titanium mesh system is needed to address these issues. Utility Model Content
