Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical robotic systems face challenges in managing emotional responses and cognitive workload of the surgical team during complex procedures, particularly during the learning phase and unexpected events, which can lead to safety concerns due to the robotic arm's proximity to bedside staff.
Innovation Solution
A surgical robotic system that adjusts its functions based on physiological responses of clinicians, such as heart rate, temperature, and vocal variations, using wearable sensors and audio/image sensors, to modify settings like speed limits, motion ranges, and environmental conditions to enhance safety and collaboration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robotic arm operates with full freedom of movement, then surgical productivity and precision are improved, but safety deteriorates when the arm is close to bedside staff during learning phase and unexpected events
Solution Approach 1:
The robotic arm's operational parameters are dynamically adjusted based on real-time detection of clinician emotional states. The system transitions from static, fixed operational modes to dynamic, adaptive control that responds to physiological signals, allowing the arm to autonomously modulate its behavior according to the emotional climate of the surgical team.
Solution Approach 2:
The system implements closed-loop feedback by continuously monitoring clinician physiological signals (heart rate, temperature, blood flow, vocal variations) and using this information to adjust robotic arm functions. The computer receives real-time data from sensors, determines emotional states, and automatically modifies system parameters accordingly, creating a self-regulating control mechanism.
2Reliability
If the system provides comprehensive real-time monitoring and dynamic adjustment, then safety and adaptability are improved, but device complexity increases
Solution Approach 1:
The computer serves multiple functions: it processes physiological signals from various sensor types, determines emotional states, identifies surgical procedure phases, and controls multiple robotic arm functions. By consolidating these diverse functions into a single integrated control unit, the system achieves comprehensive monitoring and adjustment without proportionally increasing overall system complexity.
Solution Approach 2:
The system automatically monitors its own operational context and self-regulates without requiring external intervention. The computer independently analyzes physiological data, determines appropriate responses, and adjusts system parameters autonomously, eliminating the need for complex manual control interfaces and reducing the operational burden on users.
3Productivity
If the robotic arm operates at high speed, then surgical efficiency is improved, but safety deteriorates when clinicians experience high arousal states
Solution Approach 1:
The system proactively identifies high-arousal states through physiological monitoring and preemptively reduces robotic arm speed before incidents can occur. By detecting elevated heart rate, temperature, or other stress indicators and automatically throttling arm velocity in advance, the system prevents potential harm rather than responding reactively after a problem arises.

AI summary
A surgical robotic system includes a robotic arm, a user console, and a computer. The robotic arm includes a surgical instrument, and the user console includes a handle communicatively coupled to the robotic arm or the surgical instrument. The computer is configured to receive physiological signals from a sensor monitoring a clinician, determine a physiological response of the clinician based on the received physiological signals, determine a phase or a task of a surgical procedure based on at least one of surgical sensor data or a user command to perform the task, and adjust at least one function of the surgical robotic system based on at least one of the physiological response of the clinician or the phase or task of the surgical procedure.
