Surgical Device Functional Restriction via Cross-System Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical settings, multiple smart devices often operate in isolation or with limited collaboration, leading to instability and predictability failures due to uncoordinated interactions, which can result in harmful negative feedback loops affecting patient care.
Innovation Solution
Implementing a system where one device can apply conditional restrictions on its operation based on the monitoring and data from another device, using directional synchronization to control the impact on physiological patient parameters, and adjusting operational bounds dynamically based on outcomes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple smart devices operate in isolation with limited collaboration, then device autonomy and independence are maintained, but system stability and coordination reliability deteriorate due to uncoordinated interactions and negative feedback loops
Solution Approach 1:
The patent implements a feedback mechanism where devices monitor each other's operational status and physiological parameters. The system detects when devices are operating in a way that creates negative feedback loops (e.g., both cooling devices active causing excessive temperature reduction) and automatically adjusts or restricts device operation to maintain stability while preserving autonomy.
Solution Approach 2:
The patent introduces a coordination system or intermediary layer that enables communication between devices without requiring direct integration. This intermediary facilitates information exchange about device status and patient parameters, allowing devices to coordinate their operations and avoid harmful interactions while maintaining their independent functionality.
2Ease of operation
If devices operate independently without monitoring each other's effects, then operational simplicity is maintained, but harmful feedback loops can develop affecting patient safety
Solution Approach 1:
The system continuously monitors physiological parameters and device operations to detect harmful feedback loops. When a negative feedback pattern is identified (such as both devices attempting to cool a patient simultaneously), the system provides feedback signals to the devices to adjust or restrict their operation, preventing patient harm while maintaining ease of use.
Solution Approach 2:
The patent enables devices to self-regulate based on monitored conditions. When a device detects that its operation is contributing to a harmful feedback loop, it automatically adjusts or restricts its function without requiring manual intervention, maintaining operational simplicity while preventing harm.
3Device complexity
If static coordination means are used between devices, then system configuration is simplified, but adaptability to changing patient parameters and circumstances is reduced
Solution Approach 1:
The patent implements dynamic coordination where the coordination rules and device restrictions adapt in real-time based on monitored physiological parameters and operational context. The system transitions from static pre-configured coordination to dynamic adjustment, allowing coordination behavior to change automatically according to patient conditions while keeping the configuration interface simple.
Solution Approach 2:
The system changes coordination parameters dynamically based on monitored conditions. Instead of fixed coordination rules, the system adjusts operational bounds, communication frequencies, and coordination strategies based on real-time patient parameters, maintaining simple configuration while achieving high adaptability.

AI summary
Devices, systems, and techniques for functional restriction of a device based on information from another independent system. An example first surgical device may determine that the first surgical device is capable of obtaining medical information from a second surgical device. The first surgical device may receive the medical information from the second surgical device. The first surgical device may determine that the medical information satisfies a condition. Determining that the medical information satisfies a condition may involve determining that operation of the first surgical device and operation of the second surgical device have created a negative feedback loop that negatively impacts patient health. The first surgical device may limit functional capabilities of the first surgical device based on the medical information satisfying the condition.
