Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional video-based data transmission is used for remote robotic surgery, then the system is simpler to implement, but latency delays occur and surgical performance is compromised
Solution Approach 1:
The patent replaces conventional video-based data transmission with direct digital data transmission of raw sensory information. Instead of capturing, compressing, and transmitting video frames, the system transmits raw sensor data directly to the remote site where it is processed and rendered, eliminating the latency inherent in video compression and decompression cycles.
Solution Approach 2:
The system changes the fundamental parameter of data transmission from video frames to raw sensory data packets. This parameter change enables more efficient data handling and reduces transmission latency, as raw data can be processed and updated more quickly than compressed video streams.
2Reliability
If dedicated broadband channels are used for data transmission, then real-time control and visualization are achieved, but infrastructure costs and device complexity increase significantly
Solution Approach 1:
The patent creates a universal data transmission platform that can operate over standard network infrastructure while maintaining real-time performance. The system uses a standardized data protocol that can run over existing broadband connections, eliminating the need for dedicated specialized infrastructure and making the technology accessible to more facilities.
Solution Approach 2:
The system creates a virtual copy of the operative field through real-time 3D rendering from transmitted sensor data, allowing the remote surgeon to interact with this virtual representation. This copying approach eliminates the need for complex dual-site equipment duplication while maintaining full surgical capability.
3Loss of energy
If video compression is used for data transmission, then bandwidth requirements are reduced, but information loss occurs and surgical precision is compromised
Solution Approach 1:
The patent substitutes video compression with direct transmission of essential sensory data parameters. Instead of compressing visual information, the system transmits key measurement data (position, orientation, sensor readings) directly, which is then used to reconstruct the operative field. This approach preserves all critical information while using bandwidth efficiently by transmitting only essential data.
4Object-affected harmful factors
If surgeons operate remotely from angiography suites, then radiation exposure to staff is reduced, but equipment duplication costs and facility requirements increase
Solution Approach 1:
The system creates a complete virtual copy of the operative field that can be accessed remotely, allowing surgeons to operate from any location with standard equipment. This virtualization eliminates the need to duplicate expensive angiography suite equipment at remote sites, as the entire surgical environment is replicated through software and data transmission.
Data Source
AI summary
A hardware platform includes adapters to interface with medical provisioning equipment involved in a remote robotic medical procedure at a patient site and a software system component, potentially cloud-based, to process real-time incoming data streams and a database to store the data streams for later use or archival. Each data stream can itself contain different types of sensory data. The software system component provides overall control and overrideable supervision over the remote robotic operations includes a state manager that synergistically processes the incoming data streams possibly of varying transmission rates, times of receipt or transmission, resolution, and quality. The state manager forms a near- or real-time virtual representation of the operative field. The software system component includes a data broker that can parse the RTVR into subsets data tailored to the needs of the medical provisioning and monitoring equipment, which may also be deployed and co-located at the patient site.
