Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical slave robots face challenges in balancing the need for proximity to patients during surgery while minimizing space occupancy, maintaining strength, stability, and precision, and providing adequate access for surgical staff, with existing mounting methods having limitations in accessibility, mobility, and ease of preparation.
Innovation Solution
A surgical slave robot design featuring a tower-shaped main body with a major and minor support arm system, utilizing a sliding and SCARA coupling mechanism, allowing for compact, slim, and flexible positioning of multiple robot arms, enabling easy access and quick preparation, while maintaining strength and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the slave robot is positioned close to the patient, then surgical precision and accessibility are improved, but the space required for surgical staff to approach the patient is reduced
Solution Approach 1:
The robot arm is divided into multiple segments (first robot arm, second robot arm, third robot arm) that can be independently positioned and adjusted. This segmentation allows the robot to achieve precise positioning close to the patient while the compact base design preserves space for surgical staff to move around the operating area.
Solution Approach 2:
The robot employs a multi-dimensional positioning system with arms that can move in multiple axes and directions. By utilizing vertical and lateral dimensions through the multi-arm configuration, the robot achieves close proximity to the patient without occupying excessive horizontal space that would block staff access.
2Area of stationary object
If the slave robot is mounted on the ceiling and lowered to patient position, then space occupancy is minimized, but mobility and preparation flexibility are reduced
Solution Approach 1:
The robot base is equipped with wheels that enable it to be dynamically moved to different positions within the operating room. This dynamic mobility replaces the fixed ceiling-mounted approach, allowing the robot to be repositioned easily for different surgical procedures and patient configurations while maintaining a compact footprint.
Solution Approach 2:
The robot design integrates multiple functions into a single compact platform, including the ability to move to different positions, adjust arm configurations, and accommodate various surgical instruments. This multi-functionality provides preparation flexibility comparable to ceiling-mounted systems while maintaining mobility and reducing installation complexity.
3Ease of operation
If the robot arms are made longer to reach patient, then surgical accessibility is improved, but the robot size and space requirements increase
Solution Approach 1:
The robot employs multiple segmented arms (first, second, and third robot arms) that can be independently positioned. This segmentation allows the system to achieve extended reach and surgical accessibility through coordinated arm movements without requiring any single arm to be excessively long, thereby maintaining a compact overall robot size.
Solution Approach 2:
The multi-arm configuration allows the robot arms to be nested or folded when not in use, reducing the overall space required. The arms can be positioned in a compact arrangement that minimizes the robot's footprint while still providing full surgical accessibility when deployed.

AI summary
A surgical slave robot is disclosed. The surgical slave robot, for performing a surgical operation with a surgical instrument installed on an end portion of a robot arm, can include: a main body; a major support arm that is coupled to the main body such that the major support arm is movable along one direction; a minor support arm rotatably coupled to the major support arm; and a plurality of the robot arms rotatably coupled to the minor support arm. By coupling a twofold support arm of a major and minor support arm to a tower-shaped main body and coupling multiple robot arms to the support arms, the surgical slave robot may be constructed with a compact and slim size that occupies a small amount of space, making it possible to position the surgical robot close to the patient while providing space for the surgeon to access the patient.
