Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current control consoles for surgical devices with mechanical arms lack intuitive and efficient user interfaces that align the user's view with the camera view, leading to potential discrepancies in surgical arm and camera insertion directions, which can result in collisions and suboptimal surgical procedures.
Innovation Solution
A control console with an input arm system that adjusts its direction based on the selected surgical configuration, using a processor to receive data from sensors and cameras, ensuring the input arm configuration matches the surgical configuration, and generating signals to control the surgical mechanical arm's movement to prevent collisions and optimize insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional control console with fixed input arm configuration is used, then the device complexity is reduced, but the alignment between user view and camera view deteriorates, leading to potential collisions and suboptimal surgical procedures
Solution Approach 1:
The input arm configuration is made dynamically adjustable to match different surgical configurations. The processor receives data about the selected surgical configuration and automatically adjusts the input arm's direction and orientation, transforming a static control interface into a dynamic one that adapts to various surgical scenarios, thereby ensuring consistent alignment between user view and camera view.
Solution Approach 2:
The system changes the directional parameters of the input arm based on the selected surgical configuration. By receiving configuration data from the processor and adjusting the input arm's orientation parameters (angle, direction, position), the system maintains optimal alignment accuracy across different surgical procedures without requiring complete redesign of the control console.
2Reliability
If the input arm configuration is adjusted to match each surgical configuration, then the alignment between user view and camera view is improved, but the ease of operation deteriorates due to additional adjustment requirements
Solution Approach 1:
The control console performs self-adjustment of the input arm configuration based on the selected surgical procedure. The processor automatically receives configuration data and adjusts the input arm parameters without requiring manual intervention from the surgeon, thereby maintaining high surgical safety while preserving ease of operation. The system serves itself by autonomously adapting to different surgical scenarios.
Solution Approach 2:
The system implements a feedback mechanism where the processor receives data about the selected surgical configuration and uses this information to automatically adjust the input arm orientation. This closed-loop approach ensures that the control interface remains optimally aligned with the surgical field while requiring minimal user input, thus maintaining both safety and operational simplicity.
3Measurement precision
If the input arm direction is made adjustable to prevent collisions, then the measurement precision of surgical configuration is improved, but the device complexity increases due to additional sensors and processors
Solution Approach 1:
The processor and sensor system are designed to serve multiple functions: detecting the selected surgical configuration, determining the optimal input arm orientation, and adjusting the input arm parameters. By making the control console multi-functional, the system achieves high measurement precision without proportionally increasing complexity, as the same components perform multiple critical tasks.
Solution Approach 2:
The patent merges the configuration detection, analysis, and adjustment functions into an integrated control console system. The processor combines multiple functions (receiving configuration data, calculating optimal angles, controlling input arm position) into a single centralized unit, thereby achieving high measurement precision while minimizing the overall system complexity through functional integration.
