Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical workstations with robots lack effective navigation and control systems to ensure precise and safe insertion and movement of medical instruments, particularly during procedures like liposuction, where real-time imaging and instrument tracking are crucial to avoid unintended tissue damage.
Innovation Solution
A medical workstation with a robot arm and imaging device that follows the movement of a medical instrument, utilizing a navigation system with detection devices like cameras and sensors to track the instrument's position and orientation, and a control device that adjusts the robot arm's movement based on image data to prevent the instrument from leaving the desired treatment area, while providing visual and acoustic warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a robot arm with imaging device is used to follow the medical instrument, then real-time visualization and tracking precision are improved, but device complexity increases
Solution Approach 1:
The robot arm is designed to perform multiple functions: it can hold and position the imaging device, track the medical instrument, and provide stable support. This multi-functionality reduces the need for separate dedicated tracking systems and simplifies the overall device architecture while maintaining high tracking precision
Solution Approach 2:
The robot arm acts as an intermediary between the medical instrument and the imaging device. It receives control signals from the control unit and translates them into precise physical movements of the imaging device, enabling accurate tracking without direct mechanical coupling between the instrument and imager
2Reliability
If the robot arm automatically follows the medical instrument movement, then safety is improved by preventing unintended tissue damage, but ease of operation decreases
Solution Approach 1:
The control unit continuously receives real-time data from both the medical instrument position and imaging device position, processes this information, and automatically adjusts the robot arm movements to maintain proper tracking. This closed-loop feedback system ensures safety by preventing the instrument from leaving the desired area while reducing the operator's cognitive load
Solution Approach 2:
The system performs automatic tracking and safety monitoring without requiring constant manual intervention. The control unit autonomously manages the coordination between the medical instrument and imaging device, allowing the operator to focus on the medical procedure while the system handles the complex tracking and safety monitoring tasks
3Measurement precision
If navigation system with detection devices is used to track instrument position, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The detection devices are integrated into the existing robot arm and imaging device structure rather than being separate standalone systems. The control unit combines data from multiple detection devices to determine instrument position, merging multiple functions into a unified system that reduces overall complexity while maintaining high measurement precision
