An ultrasonic surgical tool system with a tip capable of simultaneously vibrating in plural modes. The system includes a console capable of supplying a drive signal to the tip that includes plural components. Each component has a frequency characteristic that is based in part on the equivalent of current through the mechanical components of the tip. The frequency components are different from each other. Based on the application of drive signal the tip undergoes non-linear vibrations.

Systems and methods for establishing and tracking virtual boundaries. The virtual boundaries can delineate zones in which an instrument is not permitted during a surgical procedure. The virtual boundaries can also delineate zones in which the surgical instrument is permitted during the surgical procedure. The virtual boundaries can also identify objects or structures to be treated by the instrument or to be avoided by the instrument during the surgical procedure.


A vertebral augmentation system and methods for vertebral augmentation and/or fusion using same are provided. In certain embodiments, a pre-curved stylet or needle with an overlying delivery tube may be used to target a site within a bone structure, facilitating direction thereto of an expandable member useful for creating a cavity that may receive curable material to restore bone height, to reinforce the bone structure, and/or to fuse two, three, or more adjacent vertebrae. An expandable member such as, for example, a balloon can be used to create a plurality of voids by displacing bone material, where the voids can be filled with curable material to augment the vertebrae and intervening space can be filled to fuse those adjacent vertebrae.


An instrument for treating tissue during a medical procedure includes a hand-held portion and a working portion. The hand-held portion is manually supported and moved by a user and the working portion is movably coupled to the hand-held portion. A tracking device is attached to the hand-held portion for tracking the instrument. The tracking device is in communication with a control system, which is used to keep the working portion within or outside of a boundary. A plurality of actuators are operatively coupled to the working portion. The control system instructs the actuators to move the working portion relative to the hand-held portion during the medical procedure in order to maintain a desired relationship between the working portion and the boundary.


A powered surgical tool system capable of providing energization signals to plural powered surgical handpieces. The system includes a console to which at least one footswitch is attached. The footswitch can be mapped to control any one of the handpieces connected to the console. The console includes a display on which representations of the footswitch and handpieces connected to the console are presented. The representations of the handpieces are in different colors. When the footswitch is mapped to a specific handpiece, the representation of the footswitch is presented in the same color as the representation of the handpiece to which the footswitch is mapped. When plural footswitches are attached to the console, the representation of each footswitch is presented in a color corresponding to the color of the representation of the handpiece to which the footswitch is mapped.


A surgical robotic system and method for controlling an instrument feed rate. The surgical robotic system comprises a surgical manipulator for manipulating a surgical instrument and an energy applicator extending from the surgical instrument. At least one controller includes a feed rate calculator configured to calculate the instrument feed rate. A hand held pendant is operable by a user to adjust a defined feed rate of the surgical manipulator in the semi-autonomous mode.

Disclosed herein are knee replacement systems for replacing the articular surface of a distal femur. The systems include one or more unicompartmental components, namely patellofemoral, lateral condylar and medial condylar components. The components are configured such that when engaged to the femur the peripheries thereof do not cross specific locations and/or regions of the femur, namely the intercondylar notch and condylopatellar notch. The patellofemoral components described herein preferably have an extension portion extending posteriorly from a posterior periphery thereof towards an intercondylar notch of the femur without contacting the intercondylar notch of the femur when the patellofemoral component is engaged to the femur. The extension portion preferably extends posteriorly from a posterior periphery of the patellofemoral component towards the condylopatellar notch of the femur without contacting the notch.

A patient support includes a patient support surface, a DVT pump mounted in the patient support, and a port mounted at the patient support in selective fluid communication with the DVT pump. Optionally, the patient support further includes a control system to detect when a DVT device is coupled or in close proximity to the port and/or the type of DVT device. Further, the control system may be configured to control the pump based on the type of DVT device coupled to the port.


An intravenous (IV) bag support pole assembly for supporting at least one IV bag containing a surgical irrigation fluid is described. Said assembly comprises a portable cart, an IV bag support pole supported by said portable cart, having proximal and distal ends and including a plurality of segments telescopingly interfaced together, at least one IV bag hook coupled to said distal pole end for supporting the IV bag, a direct current motor having a rotatable shaft operable by an electrical portion, wherein said rotatable shaft is operatively connected to one of said segments for telescopically actuating said pole between a fully extended position and a fully retracted position, a motor control circuit electrically connected to said electrical portion of said motor for selectively providing motor power to said motor, and a slowdown circuit electrically connected to said electrical portion of said motor for periodically resisting rotation of said rotatable shaft when the motor power is unavailable, thus slowing retraction of said pole.
