Rotating Ring Surgical Station for Flexible Arm Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robotic surgical systems lack flexibility and integration, with fixed numbers of robotic arms and patient tables that do not adapt well to varying surgical procedures, leading to inefficiencies and potential disruptions during operations.
Innovation Solution
A robotic surgical station with a rotatable ring-shaped structure that supports a patient bed and variable number of robotic arms, allowing for adjustable positioning and setup based on specific surgical needs, with telescopic mounts and three degrees of rotational freedom to maintain synchronized movement of the bed and arms, and a removable patient bed for easy patient transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed number of robotic arms are used in the surgical system, then the system structure is simple and stable, but the system lacks adaptability to different surgical procedures
Solution Approach 1:
The system allows dynamic reconfiguration of robotic arms by enabling their removal and reattachment to different ports on the ring-shaped structure. This dynamic adaptability lets the system transition from a fixed configuration to a flexible one, where the number and position of robotic arms can be adjusted according to specific surgical needs without permanently altering the system architecture.
Solution Approach 2:
The ring-shaped structure with multiple ports serves as a universal mounting platform that can accommodate different numbers and types of robotic arms. This universal design allows the same base structure to support various surgical configurations, making the system multi-functional and adaptable to diverse surgical procedures while maintaining structural simplicity.
2Adaptability or versatility
If the patient table and robotic arms are fixed relative to each other, then the system is stable, but the system cannot adapt to varying surgical requirements and may cause disruptions
Solution Approach 1:
The ring-shaped structure enables dynamic positioning adjustments of both the patient bed and robotic arms while maintaining their relative synchronization. The rotatable and telescopic mechanisms allow the system to adapt to varying surgical requirements without compromising the coordinated relationship between the bed and arms, thus maintaining reliability during dynamic reconfiguration.
Solution Approach 2:
The patient bed and robotic arms are merged into a single integrated system through the common ring-shaped structure. This merging ensures that both components move and position themselves in a coordinated manner, maintaining system stability and reliability while allowing flexible adjustment to different surgical configurations.
3Productivity
If multiple robotic arms are integrated into a single station, then surgical efficiency is improved, but the device complexity increases
Solution Approach 1:
The system segments the robotic arms as independent, interchangeable modules that can be individually attached to or removed from the ring-shaped structure. This segmentation allows multiple arms to be integrated into a single station without creating a monolithic complex system, as each arm can be independently configured, maintained, and replaced based on surgical needs.
Solution Approach 2:
The dynamic reconfiguration capability of the ring-shaped structure with multiple ports allows the system to optimize its configuration for different surgical procedures. This dynamic adaptability improves surgical efficiency by enabling quick changes in system setup without requiring complete system replacement, while the modular approach keeps the integration complexity manageable.
