Polar Vision Drop-In Probe for Intraoperative Cancer Detection

Abstract

Researchers at the University of California, Davis have developed a compact intraoperative sensing solution that helps clinicians identify cancerous tissue during minimally invasive procedures. The technology provides directional insight into the presence of approved molecular imaging tracers during surgery, addressing limitations of existing bulky or surface-limited tools. By offering intuitive, real-time guidance without disrupting surgical workflow, the approach supports more precise and confident tissue removal.

Full Description

During minimally invasive and robot-assisted oncologic surgeries, surgeons increasingly rely on molecular imaging tracers to distinguish malignant tissue from surrounding anatomy. However, existing intraoperative detection tools are often large, difficult to maneuver, or unable to reliably indicate where tracer uptake is originating within the operative field. This gap limits the practical use of widely adopted imaging agents during surgery, particularly in confined or deep anatomical regions. As a result, surgeons may lack actionable feedback when attempting to localize small lesions or confirm complete tumor removal. The invention addresses this unmet need by enabling directional awareness of tracer signals directly at the surgical site.

The technology takes the form of a small, integrable probe that translates detected signals into an easy-to-interpret spatial indication for the user. Rather than producing conventional images, it conveys where signal intensity is coming from relative to the probe, supporting rapid orientation and decision-making. The solution is designed to integrate with existing surgical instruments, visualization systems, or robotic platforms. Its compact form factor and intuitive output reduce setup complexity and training burden. Overall, the approach improves surgical confidence, supports cleaner margins, and may reduce procedure time and downstream costs.
