Surgical Robot Positioning and Storage Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical robots face challenges in positioning and storage within operating rooms, requiring sufficient reach without obstructing the surgical area, maintaining stability, and minimizing space usage while allowing for easy movement and protection from contamination.
Innovation Solution
A surgical assistance robot system featuring a support structure with a prismatic body and a robot positioner that includes a vertical support for rotation and horizontal support sections, enabling the robot to be positioned and stored within a cavity, allowing for flexible deployment and storage to optimize workspace and minimize space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot base is fixed to provide stability, then the end-effector can maintain positional stability, but the robot cannot be moved and occupies permanent space in the operating room
Solution Approach 1:
The support structure transitions from a static fixed base to a dynamic mobile platform equipped with a rolling locomotive system. The base can be moved along guided tracks or autonomously navigate the operating room while maintaining stability during operation through active stabilization mechanisms.
2Adaptability or versatility
If the robot base is made mobile to clear space, then the robot can be repositioned, but positional stability may be compromised
Solution Approach 1:
A mobile support structure with active stabilization systems acts as an intermediary between mobility requirements and stability needs. The system includes feedback control mechanisms that detect and compensate for movements, ensuring the robot maintains precise positional stability even while mounted on a mobile platform.
3Adaptability or versatility
If the robot arm has multiple degrees of freedom to reach surgical regions, then the end-effector can access difficult areas, but the robot occupies more space and becomes more complex
Solution Approach 1:
The robot arm is divided into multiple segmented links connected by joints, each providing specific degrees of freedom. This segmentation allows the end-effector to reach complex surgical regions through coordinated movement of individual segments, achieving high reach capability while keeping each individual segment compact and manageable.
4Area of stationary object
If the robot is stored in the operating room to minimize space usage, then space is optimized, but the robot is exposed to damage and contamination
Solution Approach 1:
The robot is housed within a protective enclosure or sterile cover when not in use, creating a physical barrier that protects the robot from contamination while maintaining a compact footprint in the operating room. The enclosure can be quickly deployed or removed as needed.
