Abstract: Methods and systems for providing a safety mechanism for a robotically controlled surgical tool. Embodiments of the methods use sensors to detect parameters that vary by the tissue traversed by a surgical tool. The sensors detect signals arising from the interaction of the surgical tool with the tissue and provide this information to a robotic controller. For example, during drilling, the sensors may measure power, vibration, sound frequency, mechanical load, electrical impedance, and distance traversed according to preoperative measurements on a three-dimensional image set used for planning the tool trajectory. By comparing the detected output with that expected for the tool position based on the planned trajectory, identified discrepancies in output would indicate that the tool has veered from the planned trajectory. The robotic controller may then alter the tool trajectory, change the speed of the tool, or discontinue power to the tool, thereby preventing damage to underlying tissue.

Abstract: A low radiation, intra-operative method using two-dimensional imaging to register the positions of surgical implants relative to their pre-operative planned positions. Intraoperatively, a pair of two-dimensional fluoroscope images in different planes or a single three-dimensional image is acquired and compared to a set of three-dimensional pre-operative images, to allow registration of the implant region anatomy. A second set of intraoperative fluoroscope images is acquired of the surgical area with implants in place. The second set of images is compared with the first set of intraoperative images to ascertain alignment of the implants. Registration between first and second intraoperative image sets is accomplished using the implants themselves as fiducial markers, and the process repeated until an acceptable configuration of the implants is obtained. The method is particularly advantageous for spinal surgery.

Abstract: A method for verifying surgical tool placement includes attaching a guide sleeve to a surgical robot, the guide sleeve defining a guide sleeve axis; aligning the surgical robot such that the guide sleeve axis is directed at a predetermined target location; and attaching an aiming rod to the guide sleeve such that the aiming rod can rotate around the guide sleeve axis, the aiming rod having apertures along its length. The aiming rod is attached to the guide sleeve at an angle and position such that when the surgical robot is adjusted to align the guide sleeve axis with the predetermined target location, a center of each aperture of the apertures of the aiming rod and a center of the predetermined target location are collinear, independent of a rotational position of the aiming rod around the guide sleeve axis.

Abstract: A system for endoscopic surgery, comprising a first robotic arm defining the pose of an endoscopic camera, a second robotic arm defining the pose of a surgical end effector, and an irrigation nozzle configured to inject fluid under a predetermined pressure into a preselected tissue region, to generate a cavity at a surgical site. The cavity enables the camera to take images of the features of the surgical site. A controller is used to control both robotic arms, such that the pose of the endoscopic camera and the pose of the surgical end effector are known to the controller. The camera can then acquire intraoperative images of the cavity, such that an endoscopic operation can be performed in the cavity with the surgical end effector guided using the intraoperative images. Anatomic features imaged intraoperatively by the camera can be identified from preoperative images, using image registration.

Abstract: Methods and apparatus for detecting or predicting surgical tool-bone skiving are disclosed. In some embodiments, the surgical tool is movably and/or snugly disposed within a guide-sleeve. In some embodiments, a magnitude of a lateral force between the surgical tool and the guide-sleeve is measured (e.g. by a force sensor or strain sensor). The present or future skiving may be detected or predicted according to the magnitude of the lateral force. In some embodiments, an alert signal is generated in response to the detecting or predicting of the skiving.

Abstract: A method verifying the position of a surgically inserted orthopedic insert. A preoperative three dimensional image data set of the surgical site is generated, showing the bone into which the insert is to be inserted. During the insertion procedure, a series of intraoperative two-dimensional fluoroscope images are generated, each at a known pose relative to the bone, showing the insert during or after insertion into the bone. The 3-D position of the insert is determined in an intraoperative three dimensional image data set reconstructed from the series of intraoperative 2-D fluoroscope images. The reconstructed intraoperative 3-D image data set is registered with the preoperative three dimensional image data set, such as by comparison of imaged anatomical features. Once this registration is achieved, the determined 3-D position of the insert is used to implant a virtual image of the insert into the preoperative three dimensional image data set.
