Solution Overview
Problem
Accurate localization of tumors and lesions during surgical procedures is challenging due to difficulties in determining the exact location and boundaries of these tissues relative to surgical tools, often leading to excessive tissue removal.
Innovation Solution
A system utilizing structured light scanning with an antenna and a marker to determine the position and distance of target tissue relative to surgical tools, employing a structured light pattern source and detector to project and detect patterns, and a computing device to process data and display the information for precise localization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visualized using imaging modalities (ultrasound, CBCT), then tumors and lesions can be seen, but the exact location and boundaries relative to surgical tools cannot be determined
Solution Approach 1:
The patent introduces markers as intermediary objects that are placed on or near the tumor/lesion. These markers serve as a bridge between the imaging modality and the surgical tool, enabling the system to track and determine the spatial relationship between the target tissue and surgical instruments in real-time during the procedure.
Solution Approach 2:
The patent replaces traditional mechanical measurement and localization methods with optical-based structured light scanning. By projecting structured light patterns onto markers and analyzing the reflected light, the system achieves precise three-dimensional localization without mechanical contact or complex physical measurement devices.
2Reliability
If surgeons remove more tissue to ensure complete removal, then cancerous tissue is fully removed, but unnecessary healthy tissue is lost
Solution Approach 1:
The patent employs optical structured light scanning and image processing techniques to achieve precise visualization of tumor boundaries. This non-mechanical approach provides real-time, accurate spatial information that enables surgeons to differentiate between cancerous and healthy tissue, allowing for complete tumor removal while preserving surrounding healthy tissue.
3Loss of information
If traditional imaging modalities are used, then tumors are visualized, but real-time guidance during surgery is insufficient
Solution Approach 1:
The patent implements continuous real-time tracking and visualization during the entire surgical procedure. The structured light scanning system continuously captures images of markers and surgical tools, providing uninterrupted spatial information that enables dynamic adjustment and real-time guidance throughout the surgery, thereby improving surgical efficiency.
Solution Approach 2:
The patent uses markers as intermediaries that remain visible throughout the surgical procedure. These markers enable continuous tracking of the tumor location and surgical tool position, providing uninterrupted spatial information that enhances real-time guidance and surgical decision-making.

AI summary
Provided in accordance with the present disclosure are systems for identifying a position of target tissue relative to surgical tools using a structured light detector. An exemplary system includes antennas configured to interact with a marker placed proximate target tissue inside a patient's body, a structured light pattern source, a structured light detector, a display device, and a computing device configured to receive data from the antennas indicating interacting with the marker, determine a distance between the antennas and the marker, cause the structured light pattern source to project and detect a pattern onto the antennas. The instructions may further cause the computing device to determine, a pose of the antennas, determine, based on the determined distance between the antennas and the marker, and the determined pose of the antennas, a position of the marker relative to the antennas, and display the position of the marker relative to the antennas.
