Abstract: A system for tracking the position of a surgical tool manipulated by a surgical robotic system, to determine that the tool is correctly positioned and orientated. Miniature 3-D tracking cameras are mounted on the end effector of the robotic system, one viewing markers on the surgical tool, and the other markers attached to the anatomy part being operated on. The initial spatial position and orientation of the surgical tool on the surface of the anatomy part is measured, and the progress of the surgical tool into the anatomic body part is tracked using one of the miniature cameras. The cameras or sensors are close to the surgical region of interest, and all the mechanical and sensor elements necessary for the system operation are mounted within the realm of the robot. The system thus avoids interruption of communication between a remotely positioned navigation camera and the robot or patient.

Abstract: Systems and methods for robotic retraction of tissues in a surgical field. Two retractor mechanisms are used on either side of an incision. Each retractor is adapted to be held by a robotic arm, which applies force on the retractor mechanism to pull dissected tissue away from the incision, thus revealing the operative field. A force sensor is employed to measure the force on the retractor, an optional tracking sensor may be used to measure the extent of tissue retraction in two or three dimensions, and both sources of information provided to the robotic controller. By monitoring feedback from either the force sensor or the tracking sensor, the system is able to maintain equal retraction on both sides of the incision. The retractor elements incorporate mechanisms that move down the tissue as the retractors are pulled laterally.

Abstract: A robot-guided system to assist orthopedic surgeons in performing orthopedic surgical procedures on pre-positioned inserts, including for the fixation of bone fractures, and especially for use in long bone distal intramedullary locking procedures. The system provides a mechanical guide for drilling the holes for distal screws in intramedullary nailing surgery. The drill guide is automatically positioned by the robot relative to the distal locking nail holes, using data derived from only a small number of X-ray fluoroscopic images. The system allows the performance of the locking procedure without trial and error, thus enabling the procedure to be successfully performed by less experienced surgeons, reduces exposure of patient and operating room personnel to radiation, shortens the intra-operative time, and thus reduces post-operative complications.

Abstract: A system for rod bending for use in robotic spinal surgery, enabling the correct bending of a fusion rod to match the shape required to accurately pass through the heads of the pedicle screws. The system uses data generated by information provided to the robot by the surgeon's preoperative plan, optionally augmented by feedback from the robot control system of deviations encountered intraoperatively. Such deviations could occur, for example, when the surgeon decides intraoperatively on a different trajectory or even to skip screws on one vertebra, in which case, the robot will be commanded to perform the alternative procedure, with commensurate instructions relayed to the control system of the rod-bending machine. The system is also able to thin down the rod at predetermined locations along its length, adapted to be at selected intervertebral locations, for maintaining limited flexibility between vertebrae, instead of fixating them.

Abstract: A robotic system for performing minimally invasive spinal stabilization, using two screws inserted in oblique trajectories from an inferior vertebra pedicle into the adjacent superior vertebra body. The procedure is less traumatic than such procedures performed using open back surgery, by virtue of the robot used to guide the surgeon along a safe trajectory, avoiding damage to nerves surrounding the vertebrae. The robot arm is advantageous since no access is provided in a minimally invasive procedure for direct viewing of the operation site, and the accuracy required for oblique entry can readily be achieved only using robotic control. This robotic system also obviates the need for a large number of fluoroscope images to check drill insertion position relative to the surrounding nerves. Disc cleaning tools with flexible wire heads are also described. The drilling trajectory is determined by comparing fluoroscope images to preoperative images showing the planned path.

Abstract: A spinal intervertebral support implant, for fusion or for dynamic stabilization purposes. A rod, preferably in the form of a screw, is inserted obliquely from the pedicle of an inferior vertebra into the body of a neighboring superior vertebra, through the disc space. The rod can be anchored into the body of the superior vertebra by means of a force fit or a screw thread. A pile of elements is disposed on the rod in the disc space like a pile of washers, so that the compression load between vertebrae is carried partly by these elements. These elements can be inserted through the bore through which the rod was inserted in a tightly folded configuration, and deployed into their washer-like form only when in position in the intervertebral space, such that there is no need for any additional incisions.
