  • Publication number: 20210068863
    Abstract: A multi-portal method for treating a subject's spine includes distracting adjacent vertebrae using a distraction instrument positioned at a first entrance along the subject to enlarge an intervertebral space between the adjacent vertebrae. An interbody fusion implant can be delivered into the enlarged intervertebral space. The interbody fusion implant can be positioned directly between vertebral bodies of the adjacent vertebrae while endoscopically viewing the interbody fusion implant using an endoscopic instrument. The patient's spine can be visualized using endoscopic techniques to view, for example, the spine, tissue, instruments, and implants before, during, and after implantation, or the like. The visualization can help a physician throughout the surgical procedure to improve patient outcome.

  • Publication number: 20190142470
    Abstract: Provided is a spinal screw holder for a minimal invasive surgery. The spinal screw holder includes a first joint part having both penetrated ends, which is detachably coupled to a screw head fixed to a vertebra so as to be exposed to a predetermined height through an opening formed in a skin of a subject and a second joint part having both penetrated ends, which is coupled to an upper end of the first joint part and which is linearly movable in a direction that is away from the upper end of the first joint part and rotates to be bent with respect to the upper end of the first joint part after the second joint part is inserted through the opening in a state of being disposed in a straight line together with the first joint part.

  • Patent number: 9913670
    Abstract: Provided are a rod inserter for fixing a pedicle screw. The rod inserter for fixing a pedicle screw, the rod inserter including a rotational support unit having a length corresponding to a radius of lordosis formed by lumbar of vertebrae of a subject person and of which a lower end is fixed and a rotational insertion unit having a length corresponding to the radius and having one end rotatably coupled to an upper end of the rotational support unit and the other end to which an arc-shaped rod is detachably coupled. Thus, the arc-shaped rods having lengths shapes different from each other according to the number of screws respectively fixed to the vertebrae of the subject person is coupled as one device to perform the operation.
