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.

A system and related methods for performing nerve detection during surgical access using ultrasound testing during surgery.

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.

A retractor mounting assembly including an end-effector having a body extending between first and second faces. The first face is configured for attachment to an interface plate on the robotic arm of a surgical robot. The second face defines an arm mount. An arm extending between first and second ends with the first end configured for attachment to the end-effector arm mount and the second end providing a retractor mount configured for supportive attachment of a retractor.

A system for correcting a lateral curvature of a spine that can include a plurality of screws configured to be implanted in a plurality of vertebrae, and a plurality of extensions configured to be removably coupled with the plurality of screws. Some embodiments of the plurality of extensions can be curved, bent, angled, and/or offset along at least a portion thereof and can be removably coupled with a screw head of each of the plurality of screws. The system can include a connecting element or rod that is configured to be coupled with the plurality of screw heads. Some embodiments of the system can be configured such that the rod can be guided along the plurality of extensions from the proximal toward the distal end portions of the extensions and into engagement with the plurality of screws to cause the plurality of vertebrae to move laterally.

Described herein are devices for placement in surgically created soft tissue spaces, potential spaces, or cavities. The implantable devices generally include a bioabsorbable body having an open framework that facilitates attachment of tissue thereto in a manner that helps avoid post-surgical deformities. Methods for using the implantable devices in oncoplastic surgery are further described.

A retractor apparatus for a surgical robotic system includes a frame defining a central open region, a connecting member that connects the frame to a robotic arm, a plurality of coupling mechanisms for attaching a set of retractor blades within the central open region of the frame such that blades define a working channel interior of the blades, and a plurality of actuators extending between the frame and each of the coupling mechanisms and configured to move the blades with respect to the frame to vary a dimension of the working channel. Further embodiments include a surgical robotic system that includes a robotic arm and a retractor apparatus attached to the robotic arm, and methods for performing a robot-assisted surgical procedure using a retractor apparatus attached to a robotic arm.

Systems are provided that allow improved instrumentation and access during a surgical procedure including for instance a lateral approach minimally invasive spinal fusion.

A retractor for spine surgery includes a body. Left, right, and center retracting arms are coupled to the body. Left, right, and center blades are operatively coupled to proximal ends of the respective retracting arms. A retractor adaptor is configured to couple the retractor to a mount.

The systems and methods provided herein are directed to a surgical retractor which is optimized for production by additive manufacturing systems in situations where external medical supplies are interrupted or unavailable.
