Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ophthalmic surgery, such as cataract surgery, there is a need for precise control to manage quick procedures and avoid damage to structures like the posterior capsule, which existing technologies struggle to achieve efficiently.
Innovation Solution
A control apparatus and method that acquires situation information from captured images of the patient's eyeball using a surgical microscope and adjusts control parameters for the treatment apparatus, such as ultrasonic output and aspiration pressure, based on the recognized surgical phase to ensure precise and safe operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ultrasonic power is set to a predetermined value based on usage time, then the lens nucleus can be fragmented efficiently, but precise control for avoiding damage to sensitive structures becomes difficult
Solution Approach 1:
The system captures images of the surgical field using a surgical microscope and analyzes them to recognize the current surgical phase (e.g., cortex aspiration, nucleus fragmentation, posterior capsule protection). This visual feedback is fed back to the control unit, which automatically adjusts ultrasonic power and aspiration pressure parameters in real-time based on the recognized phase, enabling both efficient fragmentation and precise control to avoid damage.
Solution Approach 2:
The control parameters (ultrasonic power, aspiration pressure) are made dynamic rather than static. The system automatically adjusts these parameters based on the real-time surgical phase recognized from captured images, allowing the apparatus to adapt its behavior from high-power fragmentation mode to low-power protective mode as needed during the procedure.
2Productivity
If high ultrasonic power is used for quick procedures, then productivity increases, but the risk of damaging sensitive structures like posterior capsule increases
Solution Approach 1:
The surgical microscope continuously captures images of the surgical field, and the image analysis unit identifies when the posterior capsule is at risk or when high-power ultrasonic treatment is needed. This feedback loop enables the control unit to dynamically adjust power levels, allowing high productivity during safe phases while automatically reducing power to prevent capsule damage during critical phases.
Solution Approach 2:
The system changes operational parameters (ultrasonic power, aspiration pressure) based on the recognized surgical phase. During phases requiring speed (e.g., nucleus fragmentation), high power is applied; during phases requiring protection (e.g., posterior capsule manipulation), the parameters are automatically reduced to safe levels, thus balancing productivity with safety.
3Ease of operation
If manual control of ultrasonic power is used, then the surgeon has flexibility, but efficient automatic adjustment based on surgical phase is lost
Solution Approach 1:
The system provides automatic feedback-based control that complements surgeon flexibility. The surgical microscope and image analysis unit continuously monitor the surgical field and automatically adjust parameters based on recognized phases, freeing the surgeon from manual control while maintaining efficiency. The surgeon retains overall control authority but benefits from automated real-time adjustments.
