  • Publication number: 20190261948
    Abstract: Systems and methods for ultrafast synthetic transmit aperture (“USTA”) ultrasound imaging using coded virtual sources are described. The methods can implement spatially distinct or spatially overlapping sub-apertures with appropriate timing of transmission between the spatially overlapping sub -apertures. The systems and methods described here are capable of increasing signal-to-noise ratio (“SNR”) and spatial resolution to reduce frame rate.

  • Publication number: 20190261949
    Abstract: For region of interest (ROI) placement in quantitative ultrasound imaging with an ultrasound scanner, the ROI is automatically placed using anatomy detection specific to the quantification, signal processing for clutter, attenuation, or noise, and/or identification of regions of fluid. For quantification, multiple ROIs may be positioned automatically. The automatic placement may improve consistency of measures over time and between sonographers and may provide for better image quality with less influence from undesired signals. As a result, diagnosis and/or treatment may be improved.

  • Publication number: 20190261952
    Abstract: Rather than trying to automate what an experienced user does, rules designed for processor implementation are used for color flow imaging optimization by an image processor of an ultrasound scanner. By determining a characteristic of a scanned target, a priori information is provided. This a priori information, such as a size of a primary target, is used to select the optimization to be used. Different types of optimization may be used for different characteristics of the primary target. The values for settings may be different for different characteristics.

    Abstract: A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual articulation mechanism to articulate a jaw assembly coupled to a reload shaft connected to the handle. The manual articulation mechanism can include a ball screw mechanism that translates an articulation member responsive to rotation of an articulation knob when an instrument shaft is engaged with the handle. The articulation mechanism includes a release function that allows the jaw assembly to return to a longitudinally centered orientation. The powered handle includes a battery pack serving as a power supply for the drive system. A control system can control actuation of the motor based on user inputs and operating parameters of the stapler and can provide certain motor drive profiles for predetermined positions of the stapler. The powered handle can include a manual return mechanism.

  • Publication number: 20190261986
    Abstract: A medical instrument having a tool assembly including a pair of opposing tissue engaging surfaces for clamping tissue therebetween. The medical instrument includes a housing having a fixed handle and a movable handle mounted to the housing and selectively movable relative to the fixed handle from a first position in spaced relation relative to the fixed handle to a second position closer to the fixed handle to actuate the clamping of tissue. The medical instrument includes a selectively activatable drive assembly including a power source and a motor which is operatively coupled to the movable handle, wherein upon actuation the motor actuates the pair of opposing tissue engaging surfaces. The drive assembly includes a controller configured to variably control the rate at which the motor actuates the pair of opposing tissue engaging surfaces in response to the force exerted on the movable handle.

  • Publication number: 20190261987
    Abstract: A surgical apparatus has a clamp and a stapling mechanism. The clamp has a first jaw and a second jaw to clamp on a body tissue at a desired location for a stapling operation. The stapling mechanism is controlled by a trigger handle or a switch assembly. The surgical apparatus has a controller for providing a delay between clamping and actuating of the firing mechanism of the stapling mechanism. The delay provides for a desired amount of time for tissue compression producing a more uniform staple formation. The surgical apparatus also has an indicator. The indicator provides feedback about the status of the stapling mechanism and also displays a time of tissue compression by the clamp.

  • Publication number: 20190261988
    Abstract: Systems include an end effector having a first jaw and a second jaw, a motor system configured to actuate the end effector, and a processor. The processor is configured to determine a maximum tip deflection for the end effector, determine a torque limit based on the maximum tip deflection, and operate, subject to the torque limit, the end effector using the motor system. In some embodiments, the maximum tip deflection is determined based a type of staple cartridge being used by the end effector. In some embodiments, the type of staple cartridge identifies a length of staples fired by the end effector. In some embodiments, the firing of the staples is stalled when an applied torque exceeds the torque limit. In some embodiments, the processor is further configured to fire staples subject to the torque limit.

  • Publication number: 20190261989
    Abstract: Medical devices disclosed herein include pre-defined structures for dispensing forces onto a tissue plane in a living organism and are utilized to adjust spatial relationships, orientations, and mechanical forces in a patient treatment area. The treatment area may be a wound, an incision, or a surgically accessed area within a patient that includes oppositely disposed sections that heal more efficiently and with less scarring when force vectors of a particular magnitude and direction are applied to the treatment area. The medical device provides a structure that may be pre-stressed through planned deformation that develops desirable spatial and mechanical relationships along the tissue plane for alignment, compression, advancement, eversion, inversion, distraction, rotation, angulation, and the control or modulation of tension across the treatment area.
