Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical robotic systems face challenges in accurately identifying and orienting the robotic arms relative to a surgical table, necessitating a system to properly register and place the robotic arms for precise control during minimally invasive procedures.
Innovation Solution
A surgical robotic system incorporating a movable cart with a setup arm and an orientation device that calculates and stores orientation angles between the setup arm and the surgical table, using identification devices like near field communication chips or optically readable codes to link the orientation device, and a surgical console that correlates these angles with input device movements for precise robotic arm control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual orientation setup is used for robotic arms, then system complexity is reduced, but orientation accuracy and placement precision deteriorate
Solution Approach 1:
The system performs automatic orientation registration without requiring manual measurement or complex setup procedures. The robotic arm itself serves as the measurement device by using its own position sensors and the setup arm's motion to automatically calculate and register orientation angles relative to the surgical table, eliminating the need for external measurement tools or manual alignment procedures.
Solution Approach 2:
The patent replaces manual mechanical alignment procedures with an automated electronic registration system. Instead of using physical alignment tools, visual alignment marks, or manual angle measurement, the system uses electronic sensors, computer vision, and automated calculations to determine orientation, substituting mechanical operations with electronic and computational processes.
2Manufacturing precision
If automated orientation registration is implemented, then placement precision is improved, but setup time and operational complexity increase
Solution Approach 1:
The system performs orientation registration automatically during the setup phase before surgical procedures begin. By pre-calculating and storing orientation angles of multiple robotic arms relative to the surgical table in advance, the system ensures that precise spatial relationships are established before the actual surgery, eliminating the need for time-consuming manual alignment during operative procedures.
3Reliability
If multiple robotic arms are registered, then collision prevention is improved, but the complexity of orientation management increases
Solution Approach 1:
The system uses a universal registration approach where a single setup arm and orientation device can register multiple robotic arms. The same automated registration process applies to all arms, creating a unified coordinate system that tracks the spatial relationships of all robotic arms relative to the surgical table, thereby managing multiple arms through a single multi-functional registration mechanism rather than individual arm setup procedures.
