Intervertebral implants and graft delivery systems and methods

Abstract

The invention relates to intervertebral implants and graft delivery systems and methods. The system comprises a substrate and a mobile station, the top of the substrate is symmetrically connected with two sliding rails. Sliding blocks matched with the two sliding rails are arranged at the positions, corresponding to the two sliding rails, of the bottom of the mobile station, and each sliding block is movably arranged at the top end of the corresponding sliding rail in a sleeving mode; a traction assembly is arranged between a vertical rod and a swing rod, the front side and the rear side of the vertical rod are both fixedly connected with arc-shaped guide rails, the front side and the rear side of the swing rod are both connected with side connection guide rods matched with the arc-shaped guide rails for operation, each side connection guide rod is movably arranged in the corresponding arc-shaped guide rail, and a control panel is arranged at the top of the mobile station. According to the invention, when the intervertebral implant is implanted into the body of a patient, the implantation position, angle and depth can be adjusted according to actual needs, so that it is guaranteed that the intervertebral implant can be accurately implanted into the body of the patient, and the implantation effect of intervertebral implantation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intervertebral implant and a graft delivery system and method. Background technique [0002] Intervertebral disc, the cartilaginous connection between the vertebral bodies of two adjacent vertebrae is called the intervertebral disc. It is composed of peripheral annulus fibrosus and central nucleus pulposus. Intervertebral discs can degenerate or become damaged in different situations over time. In some cases, an intervertebral implant may be placed in the space pre-occupied by the intervertebral disc. Such implants can help maintain a desired spacing between adjacent vertebrae and / or promote fusion between adjacent vertebrae. The use of bone grafts and / or other materials within spinal implants can promote fusion of adjacent vertebral bodies. At present, doctors need to implant the intervertebral implant into the patient's body through a hand-held implant device. Th...

Problems solved by technology

At present, doctors need to implant the intervertebral implant into the patient's body through a hand-held implant device. This method of implanting a hand-held device not only makes it difficult to control the implant position and reduces the accuracy of the implant position, but also the implantation method of the hand-held device It will also increase the fatigue of the doctor, and holding the instrument for a long time for implantation work will cause the doctor's arm to feel sore, and the elderly doctor may even experience shaking hands, which will affect the implantation effect.
