Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical robot systems lack the ability to tailor instrument control parameters to individual operators, leading to imprecise movements and potential complications during surgical procedures.
Innovation Solution
A surgical robot system with a control unit that receives inputs from operators and translates them into control signals based on operator-specific control parameters, allowing for adjustment and selection of parameters during procedures based on detected events or conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If standard control parameters are used for all operators, then the system is simple to operate, but surgical precision deteriorates due to lack of customization
Solution Approach 1:
The system allows operators to customize control parameters such as wrist range of motion, instrument speed, applied force, and wrist motion gain to match their personal preferences and surgical needs. The control system translates operator inputs into control signals based on these customized parameters, enabling precise instrument control tailored to each operator's skill level and surgical style.
Solution Approach 2:
The control parameters are made dynamic and adjustable rather than fixed. Operators can modify parameters in real-time during procedures based on surgical requirements, and the system adapts the control signals accordingly. This dynamic adjustment capability allows optimization of surgical precision for different tasks without requiring system redesign.
2Measurement precision
If operator-specific control parameters are implemented, then instrument control precision improves, but system complexity increases
Solution Approach 1:
The system stores multiple sets of control parameters associated with different operators. Instead of creating entirely new control mechanisms, the system copies and retrieves pre-configured parameter sets based on operator identification, reducing the complexity of real-time configuration while maintaining high precision for each operator.
Solution Approach 2:
The control system incorporates feedback mechanisms to detect and respond to operator inputs, adjusting control signals based on real-time data about operator actions and instrument responses. This feedback loop enables automatic adaptation to operator preferences and surgical conditions, improving precision without requiring manual reconfiguration of the entire control system.
3Reliability
If control parameters are customized per operator, then surgical outcomes improve, but setup time and procedural complexity increase
Solution Approach 1:
Control parameters are pre-configured and stored in the system before surgical procedures begin. When an operator logs in or is identified, the system automatically retrieves and applies the appropriate pre-set parameters, eliminating the need for time-consuming manual configuration during critical surgical setup phases while ensuring optimal parameters are in place for reliable outcomes.
Solution Approach 2:
The system automatically identifies the operator and selects the appropriate control parameter set without requiring manual intervention. The automated parameter application process reduces setup time while maintaining customized control for improved surgical outcomes, as the system serves itself by retrieving and applying the correct configuration based on operator identification.
