Abstract: A surgical tool with a housing, and a cutter support shaft operably connected to a motor to effect rotation of the shaft with a drive transmission configured between the motor and the shaft to effect oscillating rotary movement of the shaft and cutter is disclosed.

Abstract: The invention involves a system and method for increasing positional accuracy of surgical systems that utilize magnetic or electromagnetic sensors to provide positional awareness to a surgeon or robot performing the surgery. The system takes advantage of electromagnetic tracking through sensors. These sensors are very accurate and repeatable, while being compact enough to not inhibit surgical procedures. The accuracy and repeatability of the sensors is <1 mm within a predetermined 6 inch×6 inch performance motion box. The system is constructed and arranged to map the distortion patterns of the sensor and, in real time, correct the distortion pattern to provide accurate location of anatomical structures for performance of a surgery.

Abstract: The present invention provides a method of forming pilot apertures for surgical screws. The method provides at least three points of contact to the screw shank to provide reliable positioning and retention of the bone screw. The method also provides slots or areas for insertion and retention of bone growth promoting materials which further secure the bone screw over time. The method is useful for patients of all ages, and may be particularly useful for patients that have osteoporosis or patients that are very active by providing additional securement of the bone screw to the underlying bone.

Abstract: A surgical tool that has a pair of transmissions coupled to one another to effect driving of a cutting tool in both an oscillating manner and a reciprocating manner. The transmissions are driven by a motor coupled to one of the transmissions.

Abstract: The present invention provides a cutting tool for surgical procedures. More specifically, the present invention provides a rotary surgical cutting tool which overcomes the disadvantages of prior art surgical cutting tools by providing a rotary cutting tool having straight flutes, with each side of the flute being provided with a cutting edge that permits cutting in both directions during limited oscillatory motion of the rotary surgical cutting tool. The areas between the cutting edges are provided with relief to reduce friction while the flute moves the cut material away from the cutting edges.

Abstract: A surgical implant particularly for use in spinal surgery. The implant has a pair of integral locking structures extending from opposite sides thereof for receipt in channels machined into orthopedic components like adjacent vertebral bodies. The implant has a main body containing channel portions forming communication between the adjacent bones and a space between the adjacent bones permitting bone growth into the space through the implant.

Abstract: The invention involves a system and method for controlling the movements of a multi-axis robot to perform a surgery at least on the spinal area of a human in vivo. The system includes controls and software coding to cause the robot to move in desired patterns to complete the surgery, which may include bone, disc and tissue removal, and may also include insertion of hardware for fusing adjacent bony structures.

Abstract: A robotic surgical system is provided that includes a robot connected to a computer system to help effect control of the robot. A tool is removably mounted to a distal end of a robot arm. The tool is adapted to selectively grip, move and drive an effector and a coupled fastener. The fastener is used in orthopedic surgery, and the effector is uncoupled from the fastener after it is inserted in a patient.

Abstract: A handheld tool for providing irrigation and/or suction is provided. In certain embodiments, the tool has a single cannula for providing both suction and irrigation, while in others there are separate suction and irrigation cannulas. In some embodiments, flush water is supplied by actuating a flush button which both pinches closed a suction hose and opens a flush hose. If present, the irrigation cannula may be opened by actuating an irrigation button. In certain embodiments, the irrigation and/or flush button may be provided with blade tips to pinch closed the irrigation or flush hoses in cooperation with a blade extending from the tool housing.

Abstract: Surgical systems for use in surgical procedures utilizing robotic devices. The surgical system having one or more components for housing a sensor or one or more tools for anchor or sensor delivery. The surgical system may include a surgical sensor anchor and/or a surgical sensor anchor delivery tool. A method of performing a robotically assisted surgical procedure, comprising using a surgical sensor anchor during a surgical procedure which utilizes a robot to track movement of at least one portion of a body structure undergoing a surgical procedure or to track movement of a body structure near a surgical site.

Abstract: A bone, cartilage, and disk removal tool assembly is provided with a motor mounted in a housing. A spindle is mounted for rotation to the housing. A rack-and-pinion mechanism is operably driven by the motor and connected to the spindle to oscillate the spindle for providing a rotary oscillating cutting operation. According to at least another embodiment, a plurality of cams is supported in the housing and driven for rotation by the motor. A plurality of followers is mounted for rotation to the housing, in engagement with the plurality of cams so that one rotation of the plurality of cams oscillates the plurality of followers more than once while preventing over-rotation of the plurality of followers. A peak angular acceleration of the spindle is less than nine million radians per second squared.
