3D Camera Heart Kinetics Detection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for detecting heart or myocardium kinetics during surgical operations are limited by the use of 2D cameras, which result in inaccurate data due to light refractions and manual positioning issues, making it difficult to assess ejection fraction, fractional shortening, and ventricular hemodynamic load without invasive techniques.
Innovation Solution
A 3D television camera system is used to detect spatial and mechanical movements of the heart, allowing for accurate assessment of heart kinetics by measuring distance variations, with a support system for precise positioning and data processing to evaluate parameters like ejection fraction and ventricular hemodynamic load non-invasively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a 2D television camera is used for detection, then the device complexity is reduced, but the measurement precision of heart kinetics deteriorates
Solution Approach 1:
The patent transitions from 2D camera detection to 3D detection by introducing depth measurement capability. The detection means now measures not only x-y coordinates but also z-depth variations of heart surface points, enabling accurate kinetic assessment without increasing overall device complexity significantly.
2Illumination intensity
If bright lights are used in the operating theatre, then the illumination intensity is improved, but light refractions cause harmful factors in image processing
Solution Approach 1:
The patent replaces optical image processing (which is susceptible to light refraction interference) with direct depth measurement using a detection means that measures z-coordinate variations. This substitution eliminates the harmful effect of light refractions on image processing while maintaining the benefit of bright operating theatre lighting.
3Ease of operation
If manual positioning of the detection means is used, then the ease of operation is improved, but the reliability of repeated measurements deteriorates
Solution Approach 1:
The patent introduces a positioning system with feedback control that uses anatomical landmarks and coordinate registration to automatically return the detection means to the exact same position across multiple measurements. This feedback mechanism ensures measurement reliability while maintaining operational ease through automated positioning assistance.
4Measurement precision
If invasive techniques are used for accurate detection, then the measurement precision is improved, but the object-generated harmful factors increase
Solution Approach 1:
The patent uses the heart's own surface anatomy and natural landmarks as intermediaries for measurement. By detecting depth variations of surface points relative to anatomical references, the system achieves invasive-level measurement precision without physical invasion, eliminating the harmful factors associated with invasive procedures.

AI summary
An apparatus for detecting at least one parameter, in particular kinetic, in relation to a human/animal heart/myocardium, especially during surgical operations; comprising a detector for detecting spatial or mechanical, movements of said heart/myocardium, and a controller for processing data provided by the detector for providing at least one corresponding parameter, in particular kinetic, in relation to the heart/myocardium. The detector is adapted to detect a distance, or depth, i.e. a variation in distance, or depth, of one or more points of said heart/myocardium, particularly one or more points of a corresponding surface or wall of the heart/myocardium by the detector.
