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 configured to move along a first trajectory. The tissue retraction system includes a first retractor blade coupled to the right arm assembly. The tissue retraction system includes a left arm assembly configured to move along a second trajectory. The tissue retraction system includes a second retractor blade coupled to the left arm assembly.

Tissue retraction system

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.

Transmission assembly

An example retraction system includes a first retraction assembly, the first retraction assembly including a first arm coupled to a rack, a second arm coupled to the rack, a first retractor blade coupled to the first arm and a second retractor blade coupled to the second arm. The retraction system also includes a second retraction assembly, the second retraction assembly including a carriage configured to engage a blade post having a blade coupled to a distal end and a handle coupled to a proximal end, the blade post adjustable relative to the carriage. The retraction system also includes a third retractor blade coupled to the blade post.

Surgical retraction system

Implants and instruments for providing an ideal trajectory for the insertion of instruments and screws during implantation of an interbody implant in a spinal surgery are disclosed.

Interfixated vertebral body replacement and insertion methods

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.
