ASSEMBLIES, SYSTEMS, AND METHODS FOR A NEUROMONITORING DRILL BIT

Abstract: assemblies, systems, and methods are directed at a neuromonitoring bone drill bit. the assembly may include a surgical bone drill bit, a neuromonitoring connection in electrical communication with the drill bit, and a shield extending over a distal end of the drill bit. the shield may be configured to withdraw proximally as the drill bit is advanced into a subject's bone. the assembly may be connected to a surgical drill and used in a surgical spinal procedure. in operation, the assembly may be advanced to a subject's bone at a surgical site and the drill bit may rotate into the subject's bone. in response, the shield may engage the bone and the drill bit may be advanced with respect to the shield. the shield may electrically insulate tissue from electrical current passing through the drill bit as it is inserted at the surgical site.
