Abstract: Medical cutting devices having working blade bodies, static components, retractable sheaths, sensors, navigation components and associated feedbacks and outputs are disclosed. According to an aspect, a cutting device includes a working blade body being configured for operable connection to a source of movement. The cutting device also includes a static component being configured for operable connection to the source of movement. Further, the cutting device includes one or more sensors attached to the static component and configured to acquire data in its proximity, and to communicate the acquired data to a computing device.

Abstract: Medical cutting devices having working blade bodies, static components, and computing devices for controlling device movement, feedback, and/or outputs based on sensor and navigation data and adapted for integration with manual, hand-held, and robotic systems are disclosed. According to an aspect, a cutting device includes a working body being configured for operable connection to a source of movement. The cutting device includes a static component being configured for operable connection to the source of movement. The cutting device includes an actuator that operationally attached the working body and the static component to the base for movement of the working body and the static component with respect to the base. A computing device can determine movement of the cutting blade and/or interaction of the cutting blade with an object.

Abstract: An ultrasonic surgical device capable of cutting biological tissues such as bone and cartilage. The ultrasonic surgical device includes a static casing, which sheaths an ultrasonic horn, and a lubrication film, which separates the ultrasonic horn and the static casing. The static casing, which also incorporates a plurality of fluid channels to allow passage of fluids along its length and eventual distribution of such fluids at the cutting end and biological tissue interface, inhibits the transfer of heat generated along the ultrasonic horn. The cutting end and the static casing are separated by a flexible joint, which serves to inhibit the transfer of vibrational energy, and consequently heat, from the cutting end to the static casing. As such, the static casing remains stable and can be used both to manipulate the surgical device with greater haptic control and facilitate effective penetration of larger cross-sections of biological tissue.
