3D Navigation System for Surgical Microscopes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical microscopes require manual adjustment of zoom and focus, leading to difficulty and time consumption during surgical procedures, and existing navigation systems lack effective feedback for accurate depth perception, causing surgeon eye strain and inconsistency in image comparison across medical centers.
Innovation Solution
The development of a 3D navigation system that integrates movable zoom and focus optics with a controller for automated adjustment, combined with proprioception features to provide real-time depth information, enhancing feedback through a combination of visual, tactile, and auditory cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of zoom and focus optics is used in conventional surgical microscopes, then the system structure remains simple, but the ease of operation deteriorates and time consumption increases during surgical procedures
Solution Approach 1:
The surgical microscope system performs automatic zoom and focus adjustments without requiring manual intervention from the surgeon. The system uses sensors to detect the position of surgical instruments and automatically adjusts optical parameters, allowing the system to serve itself rather than requiring constant human operation.
Solution Approach 2:
The patent replaces manual mechanical adjustment mechanisms with automated control systems. Motorized zoom and focus mechanisms are implemented, controlled by microprocessors that receive input from position sensors, substituting the need for manual mechanical manipulation during surgery.
2Adaptability or versatility
If separate narrow field and wide field scopes are used to obtain different zoom ranges, then the adaptability of the system improves, but the device complexity and difficulty of operation increase
Solution Approach 1:
The surgical microscope is designed with multi-functional capabilities to perform both wide-field overview and narrow-field detailed viewing functions. The system uses motorized zoom mechanisms and adjustable optical paths to provide multiple viewing modes within a single device, eliminating the need for separate scopes.
Solution Approach 2:
The optical system incorporates dynamic adjustment capabilities where zoom and focus parameters can be changed during operation. The system transitions smoothly between different magnification levels and field-of-view settings, providing adaptive viewing capabilities without requiring physical scope changes.
3Adaptability or versatility
If different cameras and light sources are used for different medical centers and procedures, then the adaptability to specific procedures improves, but the consistency of images deteriorates
Solution Approach 1:
The system maintains consistent image quality by controlling and standardizing key parameters such as illumination intensity, camera exposure settings, and optical magnification. Automated control mechanisms ensure these parameters remain within defined ranges across different procedures and locations, while software allows adjustment of specific settings to adapt to different surgical requirements.
