20230119442 · 2023-04-20 ·

A stretch-measurement probe includes an elongate outer sleeve, expansion feature associated with a distal portion of the outer sleeve, and an elongate inner rod disposed at least partially within the outer sleeve. The expansion feature is configured to allow a longitudinal distance between a proximal end of the outer sleeve and the distal end of the outer sleeve to be varied.

SYSTEMS AND METHODS FOR MEDICAL OBJECT TRACKING IN OBSTRUCTED ENVIRONMENTS

Systems and methods for radio-frequency-based location determination in a draped environment can include an active beacon and a control device in communication with a plurality of radio frequency (RF) transceivers. The RF transceivers can be configured to emit an RF signal responsive to transmission instructions from the control device. The active beacon can be configured to transmit a modified RF signal responsive to receipt of the RF signal from any of the plurality of RF transceivers, where the frequency value of the signal from the active beacon is shifted by an amount from the received RF signal. The plurality of RF transceivers then receive the modified RF signals. The control device can be configured to determine a location of the active beacon based upon the received modified RF signals. The draped environment can include draping material that is substantially transparent to the RF signals.

AUGMENTED REALITY SOFT TISSUE BIOPSY AND SURGERY SYSTEM
20230120638 · 2023-04-20 · ·

The combination of a marker system with binocular AR glasses to create a soft tissue procedure system used for surgery, biopsies, etc. A marker localization system is functionally integrated with augmented reality (AR) glasses. This soft tissue system can be applicable for AR surgeries in soft tissues involving mobile and static anatomies anywhere in the body, such as for example, breast, soft tissue, lungs, lymph nodes, liver surgeries, etc. By the placement of single or multiple markers and localizing the markers with a locator, such as a hand-held locator as a non-limiting example, the above-mentioned system provides a real-time intraoperative coordinate frame for the virtual projection of the markers (and the associated ROI) on/in the surgical field/biopsy field of view, using commercial off-the-shelf computer hardware (laptops, tablets, etc.) for the required image processing.
