Spinal implant configured for midline insertion and related instruments

摘要

The embodiments provide a spinal implant that is configured for midline insertion into a patient's intervertebral disc space. The spinal implant may include structural guidance features to facilitate the angular approach of fixation elements into the apertures. The spinal implant may also be a configured with a tactile or visual feedback response feature to allow the user to know when the fixation elements are fully seated within the apertures.

主权项

1. A spinal implant comprising:
a body having an upper surface, a lower surface, an anterior portion, and a posterior portion, wherein the body is configured for midline insertion between vertebral bodies of a patient's spine; and one or more apertures within the anterior portion of the body for receiving at least one fixation element, wherein at least one of the apertures is configured with a tactile or visual feedback response feature to allow the user to know when the at least one fixation element is fully seated; the tactile feedback response feature comprising a countersink with a center that is offset to an axis of the aperture, a portion of the countersink having a spherically shaped surface, and a position of the spherically shaped surface being defined by the spherical radius center.
