Force Sensing System for Surgical Self-Retaining Retractors
This invention is a single self-retaining retractor with an autoclave force sensor mounted on each side of the retractor at the tissue interface. A force sensor is connected to a processing circuit via autoclave wires and a thermocouple. The processing circuit is connected via a Bluetooth low energy (BLE) with a mobile application to display store and...

Repurposed FDA-Approved Drugs as an Optical Biopsy Stain Panel
University of Arizona researchers have developed a technology that repurposes FDA approved drugs to stain tissues in vivo, to enhance the effectiveness of optical biopsies. Alternatively, the cell staining panel could be a safer alternative to typical cell stains ex vivo/in vitro for routine optical microscopy.
Background:
Biopsies are a common...

Formulaic Imaging for Tissue Diagnosis
This patented system (U.S. Patent 9,952,157) uses a combination of green and blue fluorescence with reflectance, aimed at simple but effective contrast improvements through division, multiplication, subtraction and additions of individual images. To the best of our knowledge no other formulaic images system based on three or more components uses near-UV...
