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: The present invention provides an apparatus, system and method for providing robotically assisted surgery that involves the removal of bone or non-fibrous type tissues during a surgical procedure, in particular with assistance from real-time ultrasound images from an ultrasound probe. The system utilizes a multi-axis robot having a reciprocating tool that is constructed and arranged to remove hard or non-fibrous tissues while leaving soft tissues unharmed. The multi-axis robot may be controlled via computer or telemanipulator, which allows the surgeon to complete a surgery from an area adjacent to the patient to thousands of miles away.

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 invention involves a system and method for quickly retracting a tool from a surgical site. The system is generally constructed and arranged for attachment to a robotic arm for manipulation of the tool to perform an in-vivo surgery. The tool is constructed to retract from the surgical site upon a predetermined condition. The system and the robot can be reset when the condition has cleared so that the surgery can continue.

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 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: 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: 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: An oscillating drive mechanism for a surgical tool includes a motor having a rotor, a crank assembly hub, a link secured to the crank assembly hub, a pivot shaft, a shuttle including an arcuate rack gear secured to the link so that rotation of the crank assembly hub provides reciprocating rotary motion to the arcuate rack gear about the pivot shaft. A gear is meshed with the arcuate rack gear and is secured to an output shaft, whereby rotational motion of the motor induces rotary oscillating motion to the output shaft.

Abstract: The present invention relates to a powered surgical tool that selectively rotates a tool head (effector) to effect tissue modification during a surgical procedure, and allows for use also as a fastener driver by a simple change of end effectors and shifting a drive selector.

Abstract: A rotary surgical tool is provided and has an effector or cutter that is usable to remove or otherwise modify tissue such as bone. The tool includes a motor coupled to the effector with a single piece shaft that is integral with the effector and also serves as the motor output shaft.

Abstract: The present disclosure provides a cutting tool for surgical procedures. More specifically, the present cutting tool is suitable for bi-directional cutting and removal of soft and hard tissues for surgical procedures. The cutting tool includes a substantially rigid shaft having a shaped end portion. The shaped end portion includes a plurality of shaped talons; each talon including a body bent to retain tissue, and each talon including a cutter end. The cutter end includes both acute and obtuse cutting surface relief angles for diverse cutting action with respect to hard and soft tissues.

Abstract: A surgical tool that has a pair of transmissions coupled to one another to effect driving of a cutting tool in both bidirectional intermittent rotational manners and in opposite directions of continuous rotation. The transmissions are driven by a motor coupled to one of the transmissions which is coupled to the second transmission.

Abstract: The present invention provides for a joint fixation device and method utilizing a bone screw having a bi-directional drill point that is constructed and arranged to cut and form a hole in a bone when the screw is rotated or oscillated in both directions around the longitudinal axis of the screw. The screw can then be rotated into a final position by rotation in a single direction; and removed by rotating the screw in an opposite direction.

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.
