Abstract: Systems (10) and methods (12) of controlling an ultrasonic surgical tool (20) with a console (22) are provided. A first drive signal (40) is applied to the ultrasonic surgical tool (20). A characteristic of a harmonic signal (44) resulting from application of the first drive signal (40) to the ultrasonic surgical tool (20) is acquired. A cancellation signal (70) is generated based on the characteristic of the harmonic signal (44). The first drive signal (40) and the cancellation signal (70) are combined to produce a second drive signal (80) that is sinusoidal. The second drive signal (80) is applied to the ultrasonic surgical tool (20) such that presence of the harmonic signal (44) resulting from application of the second drive signal (80) is reduced relative to presence of the harmonic signal (44) resulting from application of the first drive signal (40).

Abstract: A patient support apparatus for transporting a patient over a floor surface is described herein. The patient support apparatus includes a drive system with a drive member, a user interface for receiving user commands from a user to operate the drive system, and a control system for operating the drive system. The control system includes a memory device configured to store a plurality of transition profiles and a controller configured to sense a plurality of positions of the drive member relative to the support structure, calculate a distance traveled by the patient support apparatus over the floor surface, compare the plurality of positions of the drive member and the distance traveled by the patient support apparatus with the transition profiles, and determine that the patient support apparatus is traveling on an inclined floor surface.

Abstract: A light source includes a first LED in communication with a first DAC; a second LED in communication with a second DAC; a third LED in communication with a third DAC; a color sensor capable of sensing light in the visible light spectrum; and one or more processors configured for: receiving color intensity values from the color sensor, determining whether the color intensity values are balanced to achieve white light, adjusting the current to the second DAC and third DAC until the color intensity levels are balanced to achieve white light at a combined intensity level, setting a new red LED current value, a new green LED current value, and a new blue LED current value to adjust the combined intensity level toward a target intensity level, and repeating the setting step until the target intensity level is achieved.

Abstract: A device for augmenting a vertebra. The device includes an expandable implant and a pedicle anchor. The pedicle anchor includes at least one anchoring element movably coupled to an anchor body. An actuator is movable within the anchor body to deploy the anchoring element into engagement with a vertebral pedicle. The anchoring element may be deployed in a same plane as a tissue support ski of the expandable implant. The actuator may be a rod including a knuckle or a cam. The tissue support ski may be recessed from an outer profile of the device. Struts of the expandable implant may be angled towards the tissue support ski in an insertion configuration. The device may be oval-shaped and provide means for rotating the expandable implant relative to the pedicle anchor, and for blocking the expandable implant in a predetermined orientation. Methods of deploying the device are also disclosed.

Abstract: Control console for a powered surgical tool that includes a transformer with a secondary winding across which the tool drive signal is present. Also internal to the transformer is a matched current source that consists of a leakage control winding and a capacitor. The current sourced by the matched current at least partially cancels out leakage current that may be present.

Abstract: A patient support apparatus for removably retaining differently-sized portable electronic devices. The patient support apparatus comprises a base, a litter with a patient support deck for supporting the patient, and a side rail. The side rail is coupled to the litter and arranged for movement relative to the base. The side rail includes a caddy comprising a back, a first brace, and a second brace spaced from the first brace. The first brace extends laterally from the back and defines a first bottom support region. The second brace extends laterally from the back and defines a second bottom support region converging toward the first bottom support region to arrange the first and second bottom support regions to provide differing points of contact for retaining differently-sized portable electronic devices.

Abstract: A first light source with a first etendue generates a first light beam to travel along a first optical path having an expanded portion formed by a collector optical system. A second light source having a second etendue less than one tenth of the first etendue forms second light, which is conducted by a light guide having a distal section with an end face. The second light is emitted from the end face as a second light beam that travels over a second optical path that resides within the expanded portion of the first optical path due to the light guide being disposed relative to the first optical path from an off-axis direction. An optical condenser receives and directs the first and second light beams to a common exit plane to form the combined light beam.

Abstract: Systems and methods for estimating a blood volume within a canister. The system may include means for detecting a fluid level of the fluid, such as a float sensor mechanism disposed within the canister. An imaging device captures an image of the fluid within the canister. A processor determines an estimated concentration of a blood component in the fluid based on the image. The processor determines a canister volume of the fluid based on the detected fluid level, and estimates the blood volume within the canister based on the estimated concentration of the blood component and the determined canister volume. The processor may trigger the imaging device to capture the image based on a change in the canister volume. An insert may be arranged within the canister and positioned adjacent to and offset from a transparent region of the canister.

Abstract: A sterilization system comprising a sterilization container for holding a surgical instrument, the sterilization container formed to allow sterilant to enter and residual sterilant to exit so that the surgical instrument in the sterilization container can be subjected to a sterilization process. The sterilization container comprises an electronic sensor module for measuring a characteristic of an environment in the sterilization container during a sterilization process. The system further comprises a station capable of being in electronic communication with the sterilization container, with the station comprising a station memory. The station is configured to track usage of the sterilization container on the station memory based on data measured by the electronic sensor module.
