Abstract: An assembly comprising a drive gear coupled to a shaft and a dial. The drive gear is configured to rotate along a first axis based on movement of the dial. The assembly includes a first linking member located along a second axis and configured to rotate about the second axis based on contact with the drive gear as the drive gear is rotated. The assembly includes a second linking member located along the second axis and configured to rotate about the second axis based on rotation of the drive gear and a coupling between the first linking member and the second linking member. The assembly includes a linking member selector configured to rotate about the first axis and for selecting at least a position corresponding to the first linking member that causes the coupling between the first linking member and the second linking member.

Abstract: Patient positioners as well as methods for using patient positioners are disclosed. An example patient positioner may include a thoracic support assembly having one or more thoracic attachment members for securing the thoracic support member to a rail. The thoracic support assembly may have a thoracic adjustment mechanism configured to shift the thoracic support assembly relative to the one or more thoracic attachment members. A lumbar support assembly may be disposed adjacent to the thoracic support assembly. The lumbar support assembly may include one or more lumbar attachment members for securing the lumbar support assembly to the rail. The lumbar support assembly may include a lumbar adjustment mechanism configured to shift the lumbar support assembly relative to the one or more lumbar attachment members. A bolster may be coupled to at least one of the thoracic support assembly and the lumbar support assembly.

Abstract: A tissue retraction system comprising a drive gear coupled to a shaft. The tissue retraction system includes a first plurality of linking members located along a second axis and configured to rotate along the second axis based on contact with the drive gear as the drive gear is rotated. The tissue retraction system includes a linking member selector configured to rotate along the first axis, wherein the linking member selector comprises a cylindrical body integrally formed with a handle. The tissue retraction system includes a right arm assembly, a left arm assembly, and a center arm that are each configured to move along trajectories. The tissue retraction system includes a first retractor blade, a second rector blade, and a third retractor blade. The tissue retraction system includes an array with tracking markers.

Abstract: A surgical wire is part of a system that includes a retractor blade defining one or more paths for the surgical wire to follow. The paths can be one or more openings, cannulations, paths, tubes, other structures, or combinations thereof. The surgical wire can be routed through the front, back, and/or middle of the retractor blade and into a vertebral body. The surgical wire can be routed through a shim in communication with the retractor blade and into a vertebral body Systems and methods are used to insert surgical wires into bone. Systems and methods are used for removing surgical wires from bone. Systems include those for gripping and pulling or pushing surgical wires. Systems include those that interact with a retractor (e.g., an arm, body, or blade thereof) to facilitate removal of the surgical wire.
