Abstract: An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates.

Abstract: A passive end effector of a surgical system includes a base, a first mechanism, and a second mechanism. The base attaches to an end effector coupler of a robot arm positioned by a surgical robot. The first mechanism extends between a rotatable connection to the base and a rotatable connection to a tool attachment mechanism. The second mechanism extends between a rotatable connection to the base and a rotatable connection to the tool attachment mechanism. The first and second mechanisms pivot about the rotatable connections to constrain movement of the tool attachment mechanism to a range of movement within a working plane. The tool attachment mechanism is configured to connect to a surgical saw including a saw blade for cutting.

Abstract: A medical imaging system includes a movable station having a C-arm, a collector, an X-ray beam emitter, and a controller. The collector is attached to a first end of the C-arm. The X-ray beam emitter faces the collector to emit an X-ray beam in a direction of the collector and is attached to a second end of the C-arm. The controller moves one of the X-ray beam emitter and the collector to a first offset position along a lateral axis orthogonal to the arc, and obtains a first set of images by rotating the collector and the X-ray beam emitter along the arc about a scanned volume. The controller moves the one of the X-ray beam emitter and the collector to a second offset position along the lateral axis, and obtains a second set of images. The controller combines the first and second set of images to generate a three-dimensional image of the scanned volume.

Abstract: Implants, systems, and methods of reverse dynamization. The implants, such as expandable spinal implants, bone plates, and intramedullary nails, are securable to bone. The implant may have a moveable component creating a semi-rigid configuration to allow for micro-motion of the bone for a period of time. The moveable component is changeable, for example, based on material properties, change of state, or mechanical or electrical operation, to a static condition creating a rigid configuration to prevent subsequent movement of the bone. The reverse dynamization implants may be used to accelerate bone healing and obtain superior bone fracture healing.

Abstract: A surgical system includes a camera tracking system that determines a first pose transform between a first object coordinate system and the first tracking camera coordinate system based on first object tracking information from the first tracking camera which indicates pose of the first object.

Abstract: The disclosed technology relates to robotic surgical systems for improving surgical procedures. In certain embodiments, the disclosed technology relates to robotic surgical systems for use in osteotomy procedures in which bone is cut to shorten, lengthen, or change alignment of a bone structure. The osteotome, an instrument for removing parts of the vertebra, is guided by the surgical instrument guide which is held by the robot. In certain embodiments, the robot moves only in the “locked” plane (one of the two which create the wedge—i.e., the portion of the bone resected during the osteotomy). In certain embodiments, the robot shall prevent the osteotome (or other surgical instrument) from getting too deep/beyond the tip of the wedge. In certain embodiments, the robotic surgical system is integrated with neuromonitoring to prevent damage to the nervous system.
