  • Patent number: 9570842
    Abstract: A magnetic connection system suitable for use with a wireless ultrasound probe which utilizes a plurality of magnets to facilitate coupling between said probe and a diagnostic or clinical device in a manner which minimizes the effects of stray magnetic fields on the device.
    Type: Grant
    Filed: August 3, 2010
    Date of Patent: February 14, 2017
    Assignee: Koninklijke Philips N.V.
    Inventors: Timothy F. Nordgren, Tracy C. Brechbiel, John Douglas Fraser

  • Patent number: 5752517
    Abstract: Intraoperative ultrasound probes are described having contoured side surfaces which enable the probe to be held between the fingers of a surgeon during a surgical ultrasound procedure. The probes advantageously permit the surgeon to conduct a tactile examination of organs of a patient with the hand and fingertips while holding the probe.

  • Patent number: 5482047
    Abstract: An intraoperative ultrasonic transducer probe is described comprising a handle section and a transducer section which resemble a tiny leg and foot. The two sections are obtusely angled relative to each other so that the physician may continue to clearly view the surgical site while holding and manipulating the probe. The extension of the transducer section away from its point of attachment to the handle section results in the toe of the foot being insertable under unincised tissue, enabling the surgeon to ultrasonically examine organs and tissue peripheral to the surgical site and to follow a vessel even beyond the incision. The transducer section is completely encapsulated in a rubberlike material which electrically insulates the transducer from the patient, enables the probe to be easily sterilized, and further provides an inherent standoff between the transducer and the contact surface of the probe.
