Surgical Robot Support Body Positioning for Arm Reach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical robots face challenges in accurately positioning and maintaining surgical sites within the reachable range of their mechanical arms, leading to potential deviations and injuries during operations.
Innovation Solution
A surgical operation monitoring system that includes a support device and a surgical robot, which acquires the position of the surgical site and determines an allowable moving range to align it with the mechanical arm's range, ensuring the site remains within the arm's operational area through controlled movement of the support body and arm adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the surgical robot uses fixed mechanical arm range, then the device complexity is reduced, but the surgical site may deviate from the actuating end during operation
Solution Approach 1:
The system continuously monitors the position of the surgical site and the actuating end of the mechanical arm, comparing their coordinates to detect deviations. When deviation exceeds a threshold, the system automatically generates adjustment commands to realign the surgical site with the actuating end, ensuring positioning accuracy throughout the surgical operation.
Solution Approach 2:
The surgical robot system performs self-adjustment by automatically detecting position deviations and executing correction commands without requiring manual intervention. The control system autonomously processes monitoring data, calculates required adjustments, and executes them through the mechanical arm to maintain optimal positioning.
2Adaptability or versatility
If the support body is fixed in position, then the device complexity is reduced, but the surgical site cannot be adjusted to match the mechanical arm's reachable range
Solution Approach 1:
The support body is transformed from a fixed structure to a dynamically adjustable one. The driver controls the support body to move along the stand, allowing real-time position changes based on the surgical procedure requirements. This dynamic positioning enables the surgical site to be aligned with the mechanical arm's actuating end while maintaining stability during operations.
3Productivity
If manual adjustment is used to align surgical site with mechanical arm, then the device complexity is reduced, but the productivity decreases due to time-consuming adjustments
Solution Approach 1:
The system continuously monitors the positions of the surgical site and actuating end, automatically detecting deviations and triggering real-time adjustments. This closed-loop feedback mechanism eliminates manual measurement and adjustment procedures, significantly reducing the time required for positioning alignment and improving surgical productivity.
Solution Approach 2:
The surgical robot system performs autonomous position monitoring and self-adjustment without requiring surgical personnel to manually intervene. The control system automatically processes position data, calculates corrections, and executes adjustments, thereby reducing operational time and enhancing productivity.

AI summary
A surgical operation monitoring method applied to a surgical operation monitoring system comprises: acquiring a position of a surgical site of a surgical object at a first moment; under the condition that the position of the surgical site at the first moment exceeds a moving range of an actuating end of a mechanical arm, determining an allowable moving range of the surgical site at the first moment; and under the condition that the allowable moving range of the surgical site at the first moment and a moving range of the actuating end of the mechanical arm have an overlapping range, controlling a driver to drive a support body to move so that the support body drives the surgical site to move into the overlapping range.
