Implant for anterior spinal fusion in the lumbar spine

摘要

The utility model relates to medicine, in particular to neurosurgery and orthopedics, and can be used to perform stabilizing operations in the treatment of degenerative-dystrophic, deforming diseases of the spine and the consequences of its injuries. The technical problem of the utility model is to develop an implant that provides increased efficiency and stability anterior interbody fusion, devoid of multicomponent composition, having individual sizes and low cost. The technical result of this utility model is to increase the stability of spinal fusion, including reducing the time of surgery, reducing trauma to soft tissues, and reducing the financial cost of manufacturing an implant. The result is achieved due to the fact that a one-component implant for anterior spinal fusion of the spine in the lumbar includes a body with through grooves, non-parallel surfaces, tapering to the rear face and having a relief structure, channels for screws, hole for the tool-guide a body, and the body is made of titanium by 3D printing according to the dimensions determined on the preoperative planning, it contains grooves filled with porous titanium nickelide, and in the central part of the working face of the body there is a combined hole for a guiding tool containing a central threaded hole and perpendicular to its diameter the middle line of the said face is a vertical groove and at equal distance from the said combined hole channels for fixing screws begin to pass at an angle of 45 ° to the horizontal plane, opening on opposite surfaces of the housing.
