  • Publication number: 20200222025
    Abstract: A 3D ultrasonic diagnostic imaging system produces 3D display images at a 3D frame rate of display which is equal to the acquisition rate of a 3D image dataset. The volumetric region being imaged is sparsely sub-sampled by separated scanning beams. Spatial locations between the beams are filled in with interpolated values or interleaved with acquired data values from other 3D scanning intervals depending upon the existence of motion in the image field. A plurality of different beam scanning patterns are used, different ones of which have different spatial locations where beams are located and beams are omitted. In a preferred embodiment the determination of motion and the consequent decision to use interpolated or interleaved data for display is determined on a pixel-by-pixel basis.

  • Publication number: 20200222058
    Abstract: A compression device, useful for applying circumferential compression to an object, includes a simplified cinch mechanism. The device includes a guidance slide, a jamming feature/pull tab, a buckle assembly and a cinch strap, which form a loop for placing about an object. The cinch strap includes both an inner portion, anchored to the jamming feature, and an outer portion, anchored to the guidance slide. The inner portion of the cinch strap passes through the guidance slide to an adjustable, locking side of the buckle assembly, and the outer portion of the cinch strap passes from the adjustable, locking side of the buckle assembly to the guidance slide. The cinch strap can move freely when pulled on by the inner portion and lock when pulled on by the outer portion, such that an inner circumference of the device is adjustable but can maintain a minimum circumferential length after tension is applied.

  • Publication number: 20200222059
    Abstract: Embodiments of the present invention are directed to devices, systems and methods adapted for implementing intermittent displacement of blood to mitigate peripheral nerve neuropathy such as that induced by chemotherapeutic agents (i.e., chemotherapy-induced neuropathy (CIN)) that are administered to a patient. Such devices, systems and methods advantageously provide for precise, uniform and controlled blood flow occluding (and optionally blood displacing) compression along irregular surfaces of an appendage of a patient. Such precise, uniform and controlled blood occluding compression is imparted upon the epidermal and dermis skin layers within the aforementioned areas of a patient's extremities to decrease the time that free nerve endings located in the epidermal and encapsulated nerve endings located in the dermis skin layers are exposed to nerve damaging chemotherapy chemicals, thereby substantially decreasing CIN caused by prolonged exposure to such chemicals.

  • Publication number: 20200222061
    Abstract: One embodiment relates to a handheld surgical instrument that comprises a rotary surgical end effector and a coupler configured to cause rotation of the same. The handheld surgical instrument further comprises a motor, which is configured to drive a motor output region. The handheld surgical instrument further comprises a transmission, which defines a transmission input region that interfaces with the motor output region and a transmission output region coupled to the transmission input region. The transmission output region is operably coupled to the coupler, and the transmission is configured to alter the speed of the coupler relative to the motor output region. The motor output region and the transmission input region interface one another at a motor-transmission interface, and the motor-transmission interface comprises a motor-transmission backlash such that drive of the motor output region within the motor-transmission backlash does not cause rotation of the rotary surgical end effector.

    Abstract: An adapter assembly for connecting an end effector to an actuation assembly includes a base member defining a plurality of notches spaced at least partially about a circumference of the base member, a handle supported on the base member and rotatable about a longitudinal axis of the base member, and a latch mechanism supported on the handle assembly and selectively engageable with the base member. The latch mechanism includes a button member and a locking member. The button member is movable between a first position in which the locking member is received within one of the plurality of notches to lock the handle relative to the base member, and a second position in which the locking member is spaced from the plurality of notches to unlock the handle relative to the base member.

  • Publication number: 20200222063
    Abstract: A modular system for total knee arthroplasty includes a modular trial implant assembly. The modular implant assembly includes an elongate shaft configured for insertion into an elongate cavity in a bone, a reamer removably coupleable to the elongate shaft via a connection that allows the reamer to rotate while the elongate shaft remains in a substantially fixed angular orientation. The reamer has an outer surface that tapers toward the distal end configured to form a tapered cavity in an end of a bone in which the reamer is inserted and rotated. The modular trial implant assembly further includes a trial implant removably coupleable to a proximal end of the reamer. A modular final implant assembly includes an elongate stem, a tapered body and an implant body, each having a size and shape that can substantially correspond to a size and shape of the elongate shaft, the reamer and the trial implant, respectively.

  • Publication number: 20200222065
    Abstract: An electromagnetic intramedullary nail screw positioning system is used to assist an orthopaedic surgeon to correctly aligned a screw drill guide with a screw receiving aperture in an intramedullary nail during surgery. However due to the large number of different types of intramedullary nail, the system must be calibrated during each surgery. An improved calibration system is described that no longer requires the surgeon to perform the calibration during the surgery in order to save time and improve robustness. The system is periodically calibrated and a memory stores offset information for a range of nails types relative to a reference nail. During surgery, the surgeon enters a nail identifier, and the system looks up the associated offset and applies this offset to the measured signals to guide alignment of the screw drill guide with the screw receiving aperture.

  • Publication number: 20200222066
    Abstract: A drill guide system provides a means of improved tunnel placement accuracy by allowing the drill guide to articulate to seat against the bone being drilled. The drill guide includes an articulating drill guide adapter constructed in four parts: a top cap, a thumbscrew, a lock tab, and a spring mechanism. The drill guide adapter is part of an aimer arm which mates with a handle on the proximal end and an aimer guide on the distal end. The drill guide adaptor allows the aimer guide to articulate relative to an irregular mating surface, allowing for increased area contact between the aimer guide template and bone. Examples of the drill guide adaptor also include a means for locking the aimer guide into place relative to the aimer arm.

    Abstract: A guidewire for use in penetrating through complex and stenosed lesions. The distal tip of the guidewire has a roughened surface to increase frictional engagement with calcified and fibrous tissue to increase the penetration of the distal tip and the guidewire into and through the lesion and reduce the likelihood of deflection of the guidewire tip. The average surface roughness of the distal tip is in the range from 1 micron to 200 microns.
