AI Technical Summary

Technical Problem

Surgical imaging systems often fail to discern hidden structures and dimensions in three-dimensional space, limiting the information communicated to clinicians during operations.

Method used

A surgical visualization system utilizing structured light and spectral emitters to emit electromagnetic radiation, combined with image sensors and control circuits, constructs a model of anatomical structures and determines margins around target tissues, enabling precise identification and avoidance of critical structures.

Benefits of technology

Enhances surgical precision by providing real-time, three-dimensional models and distance information, allowing clinicians to make informed decisions and avoid inadvertent damage to critical structures.

Abstract

Disclosed herein is a surgical visualization system that can include a structured light emitter, a spectral light emitter, an image sensor, and control circuitry. The structured light emitter can emit a structured pattern of electromagnetic radiation onto an anatomical structure. The spectral light emitter can emit electromagnetic radiation including multiple wavelengths, at least one of which can transmit through a portion of the anatomical structure and reflect off a target tissue. The image sensor can detect the structured pattern of electromagnetic radiation reflected off the anatomical structure and the at least one wavelength reflected off the target tissue. The control circuit can receive signals from the image sensor, construct a model of the anatomical structure, detect the location of the target tissue, and determine a margin around the target tissue based on at least one signal received from the image sensor.
