Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single robotic arm is used for navigation and surgical assistance, then the system structure is simplified, but the system cannot perform multiple surgical actions simultaneously and limits surgical methodology
Solution Approach 1:
The robotic system is divided into multiple independent robotic arms (at least two), each capable of performing different surgical functions simultaneously. This segmentation allows one arm to handle navigation tasks while another performs surgical interventions, thereby increasing surgical methodology flexibility without requiring a completely integrated monolithic system.
Solution Approach 2:
Each robotic arm is designed with universal end effectors that can be configured to perform multiple surgical functions. The arms can be equipped with different tools (drills, screwdrivers, cameras, navigation devices) to handle various surgical tasks, making the system adaptable to different surgical approaches while maintaining a relatively simple base structure.
2Adaptability or versatility
If the robotic navigation system is made stationary for stability, then positioning accuracy is improved, but the system cannot be repositioned during the procedure to accommodate different surgical approaches
Solution Approach 1:
The robotic navigation system incorporates dynamic positioning capabilities with motorized bases that allow the system to be repositioned during surgery. Once positioned, the system provides stable, precise navigation through active stabilization and continuous tracking, maintaining measurement precision while enabling adaptability to different surgical approaches through controlled movement when needed.
3Reliability
If passive guidance is used to minimize system intervention, then the system remains simple to operate, but patient movement cannot be actively compensated and long surgical constructs are difficult to manage
Solution Approach 1:
The robotic system implements active feedback mechanisms through machine vision systems and tracking devices that continuously monitor patient anatomy and surgical instrument positions. This feedback enables real-time compensation for patient movement and maintains guidance accuracy while the collaborative control interface keeps operation simple by allowing surgeons to override or adjust robotic guidance as needed.

AI summary
Devices, systems, and methods for robot-assisted surgery. A surgical robotic system with integrated navigation and multiple surgical arms may assist a user with one or more surgical procedures. The base station may include a motorized propulsion and positioning system to transport the robotic system. The system may utilize a powered machine vision end effector, which couples to the surgical arm, to provide specialized motion to an instrument. A sterile drape assembly may maintain sterility and preserve electrical connectivity. Ultrasound tracking may be used for registration, patient tracking, or guided tracking of instruments, for example.
