Vertebral implant, vertebral fastening device of the implant and implant instrumentation

摘要

This disclosure provides vertebral implants, fastening devices for vertebral implants, and implant instrumentation, and various combinations thereof. In some embodiments, the implant comprises a peripheral wall extending according to a vertical axis between upper and lower surfaces of the implant, with each such surface configured to be placed in contact with a vertebral structure, respectively, at the top and the bottom of the vertebral segment replaced by the implant. Some embodiments comprise fastening means, deployment of which anchors the implant in the lower and upper vertebral structures. Some fastening means may be deployed by sliding parallel to the vertical axis of the implant, and may comprise a plate with at least one part remaining in contact with the peripheral wall of the implant when deployed and a pointed end projecting from one of the upper and lower surfaces of the implant to enter a vertebral structures on completion of deployment.

主权项

1. An implant for corpectomy of a spine having a longitudinal axis, the implant having a longitudinal axis and being sized to replace a removed segment of the spine with the longitudinal axis of the implant disposed generally parallel to the longitudinal axis of the spine, the implant comprising a peripheral wall; an upper spinal contact surface; a lower spinal contact surface; an upper and lower fasteners each having a retracted position and a deployed position, each of upper and lower fasteners comprising a plate that remains in contact with the peripheral wall when the fastener is deployed, and each of the upper and lower fasteners comprising a sharpened end configured to penetrate an unremoved spinal segment during deployment to retain the implant to that unremoved spinal segment, with the sharpened end of the upper fastener projecting from the upper spinal contact plate and the sharpened end of the lower fastener projecting from the lower spinal contact plate.
