| 20110130761 | Robotic guide assembly for use in computer-aided surgery - A system for guiding resurfacing operations on at least a portion of a joint of at least one bone is provided and uses a guide with actuators (motors) controlled by a computer to position a cutting tool relative to a bone so that the bone surface can be cut in a flexible and accurate manner. | 06-02-2011 |
| 20100234770 | COMPUTER ASSISTED ORTHOPEDIC SURGERY SYSTEM FOR LIGAMENT RECONSTRUCTION - A computer assisted orthopedic surgery system for ligament graft reconstruction includes a system for obtaining data indicative of a location for ligament graft placement with respect to at least a first bone and a second bone. The system includes a position determining device that is capable of tracking the relative movements of the first and second bones using reference bodies that are attached to the first and second bones and a pointer that has a tip for contacting a surface of at least one of the first and second bones to capture one or more reference points. The system further includes a computer that is configured to determine and track intraoperative positions of the reference bodies and the pointer and to provide isometric and impingement data for a ligament graft placement based on a realistic simulation of a trajectory of a deformable ligament graft. | 09-16-2010 |
| 20100130986 | SURGICAL ROBOTIC SYSTEM - In one embodiment, a surgical robotic system includes a main controller and a motor unit assembly that is associated with a robot and is in communication with the main controller. The motor unit assembly has a non-sterile motor unit and a sterile enclosure that surrounds and contains the motor unit. The motor unit includes at least one motor and a motor controller that is operatively connected to the motor unit, wherein the motor unit and the enclosure are configured to permit attachment between the motor unit and the controller. | 05-27-2010 |
| 20090062869 | MINIMALLY INVASIVE BONE FIXATION CLAMP FOR NAVIGATED SURGERIES - In one embodiment, a device for fixing a first object to a second object during a navigated surgery includes a body; a pair of articulating arms that are pivotally connected to the body; and a pair of deformable, elastic components that are detachably coupled to an inner face of the articulating arms so as to permit removal and replacement of the components relative to the articulating arms. An exposed surface of the elastic components is intended to contact the second object to permit the device to be securely attached to the second object. | 03-05-2009 |
| 20090018445 | ULTRASONIC BONE MOTION TRACKING SYSTEM - A computerized bone motion tracking system according to one exemplary embodiment is configured to: provide a non-invasive means for accurate measurement and tracking of the motion of a bone using a volumetric ultrasound transducer and a three dimensional position measurement system; provide relative measurements of one bone relative to another bone of a joint; decompose relative joint motion into specific components; and measure joint instability and range of motion. | 01-15-2009 |
| 20080319448 | SYSTEM AND METHOD FOR DETERMINING AN OPTIMAL TYPE AND POSITION OF AN IMPLANT - A computer-assisted orthopaedic surgery system includes a device for generating a three dimensional geometrical surface model of a first bone and a database containing three 3 dimensional implant models of a plurality of available implants. The system includes a computer that is configured to permit a user to select from the database a first implant and display on a screen the three dimensional implant model of the first implant. The computer superimposes on the screen the implant model on top of the model of the first bone such that the two models are visually identifiable from one another. | 12-25-2008 |
