Optical Tissue Differentiation System for Parathyroid Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical methods for differentiating between parathyroid and thyroid tissues during surgeries are subjective, time-consuming, and prone to complications due to the small size and variability in location of parathyroid glands, leading to accidental removal or damage during thyroid and parathyroid surgeries.
Innovation Solution
A system utilizing near-infrared auto-fluorescence and laser speckle contrast imaging to differentiate between parathyroid and thyroid tissues by collecting and analyzing optical signals, providing real-time intraoperative differentiation and reducing surgical time and complications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual inspection and subjective surgical methods are used to differentiate parathyroid and thyroid tissues, then the surgical procedure is simple and quick to perform, but the differentiation accuracy is low and accidental removal or damage occurs frequently
Solution Approach 1:
The patent introduces an optical imaging system as an intermediary tool between the surgeon and the tissue. The system uses near-infrared light sources and detectors to capture optical signals from the tissue, providing objective differentiation data that assists the surgeon without requiring the surgeon to directly interpret complex tissue characteristics
Solution Approach 2:
The patent replaces subjective visual inspection and manual surgical judgment with an optical detection system. The mechanical/visual process of tissue identification is substituted with an optical field-based detection method that measures optical signal intensities and patterns to objectively differentiate tissue types
2Reliability
If extensive surgical exploration is performed to locate and differentiate parathyroid glands, then the risk of missing or damaging glands decreases, but the surgical time increases significantly
Solution Approach 1:
The patent applies preliminary action by performing optical imaging and tissue differentiation before the surgeon begins extensive exploration. The system pre-identifies and marks the locations of parathyroid glands using optical signal analysis, allowing the surgeon to proceed with confidence and reduced exploration time
Solution Approach 2:
The patent implements real-time feedback during surgery through continuous optical monitoring. The system provides ongoing differentiation information that guides surgical actions, allowing dynamic adjustment of the surgical approach based on real-time tissue identification rather than relying on pre-planned extensive exploration
3Ease of operation
If subjective surgical judgment is used for tissue differentiation, then the surgical equipment and procedures remain simple, but the objectivity and consistency of differentiation are poor leading to complications
Solution Approach 1:
The optical imaging system serves as an objective intermediary that removes subjectivity from tissue differentiation. The system measures physical optical properties (signal intensities, spectral characteristics) that are independent of surgeon experience or judgment, providing consistent and reproducible differentiation results
Solution Approach 2:
The patent replaces the mechanical process of visual inspection and tactile assessment with an optical measurement system. This substitution transforms subjective surgical judgment into objective optical data analysis, maintaining ease of surgical operation while dramatically improving differentiation objectivity and consistency
