Foot Pedal OCT Display Control for Vitreoretinal Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During vitreoretinal surgery, surgeons face challenges in controlling OCT image displays due to the need for hands-free operation, as hand-operated or voice-operated controls are impractical, limiting the ability to quickly and accurately navigate through tissue layers.
Innovation Solution
A foot pedal controlled OCT-display system that allows surgeons to navigate through tissue layers using varying pressure sensitivity, enabling directional control with the forefoot or hindfoot to display next or previous tissue layers, and optional fast navigation with increased pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hand-operated or voice-operated controls are used for OCT image display, then the control functionality is available, but the surgical operation becomes difficult or impractical due to hands being occupied and voice commands being unreliable
Solution Approach 1:
A foot pedal device serves as an intermediary control mechanism between the surgeon and the OCT display system. The foot pedal allows surgeons to navigate through tissue layers and control OCT image display without using their hands or voice, thereby maintaining surgical sterility and focus while providing reliable control functionality.
2Ease of operation
If foot pedal control is implemented for OCT display, then hands-free operation is achieved, but the device complexity increases
Solution Approach 1:
The control functionality for OCT display is extracted from the main surgical system and implemented as a separate, simple foot pedal device. This extraction allows the pedal to be a standalone, low-complexity component that interfaces with the existing OCT system through standard communication protocols, minimizing the increase in overall system complexity.
3Loss of information
If multiple tissue layers are displayed simultaneously, then comprehensive tissue information is provided, but the navigation through layers becomes time-consuming
Solution Approach 1:
The system performs preliminary actions by automatically organizing and pre-loading multiple tissue layer data in memory before the surgeon needs to navigate through them. The foot pedal control enables sequential access to these pre-organized layers, allowing rapid navigation without the time-consuming process of loading or searching for each layer individually during surgery.

AI summary
OCT-display for vitreoretinal surgery may be foot pedal controlled. Specifically, the tissue layers displayed in an en face image generated from OCT scanning may be navigated downward or upward based on user input supplied by a foot pedal device.
