Problem
Current robotic surgical systems lack the ability to interoperate with recently developed portable systems such as mobile phones and tablets without requiring significant modifications to their hardware, firmware, and software.
Innovation Solution
The system embeds control information within video signals using steganography techniques, allowing auxiliary systems like mobile devices to remotely control primary systems, such as robotic surgical systems, by modifying their operations based on extracted control information, while ensuring data security and integrity through checksums and cryptographic features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing robotic surgical systems are modified to accommodate portable devices like mobile phones and tablets, then interoperability with new devices is improved, but system complexity and modification costs increase significantly
Solution Approach 1:
The system uses a universal video input interface that can accept signals from multiple device types (traditional cameras, mobile phones, tablets) without requiring device-specific modifications. The video processing module universally handles different video formats and extracts control information from any auxiliary system connected via video input, making the robotic surgical system adaptable to various portable devices while maintaining the same hardware interface.
Solution Approach 2:
The system introduces a video signal as an intermediary carrier that translates control commands from portable devices into a format the robotic surgical system can understand. Instead of directly integrating complex communication protocols from mobile devices, the control information is embedded within standard video signals, which act as a mediator between the auxiliary system and the robotic system, simplifying the integration process.
2Adaptability or versatility
If control information is extracted from video signals using steganography techniques, then interoperability with auxiliary systems is improved, but data extraction complexity increases
Solution Approach 1:
The system extracts control information from video signals by isolating and processing specific data elements embedded within the video stream. The video processing module separates control commands from the visual content, extracting only the necessary control information while discarding the rest of the video data. This selective extraction approach enables remote control functionality without requiring the entire video processing pipeline to be overly complex.
3Reliability
If cryptographic features are implemented for authentication and authorization, then data security is improved, but system processing time increases
Solution Approach 1:
The system performs authentication and authorization checks in advance, before processing surgical control commands. By implementing cryptographic verification preliminarily, the system ensures that only authenticated users can control the robotic system, while minimizing the impact on real-time surgical operations. The preliminary authentication establishes security credentials that can be reused for subsequent commands, reducing repeated processing time.
