Surgical Robot Control for Patient Table Repositioning Without Undocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotically-assisted surgical systems require the repositioning of robotic arms and patient tables during procedures, which is cumbersome and disrupts the surgical process, as staff must undock and reposition the arms, leading to inefficiencies and potential inaccuracies in surgical maneuvers.
Innovation Solution
A surgical robotic system with a user console, control tower, and patient subsystem that allows for the repositioning of the patient table without undocking the robotic arms, utilizing a network topology for real-time communication and control, enabling precise control and alignment of surgical instruments and maintaining high positional accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If robotic arms are repositioned during surgical procedures, then patient repositioning is achieved, but surgical process continuity is disrupted and operational complexity increases
Solution Approach 1:
The system dynamically adjusts robotic arm positions and patient table positions independently, allowing the patient to be repositioned without moving the robotic arms. The robotic arms maintain their docking position while the patient table moves to a new position, enabling continuous surgical operations without interruption.
Solution Approach 2:
The system separates the control of robotic arms from the control of the patient table. The robotic arms remain fixed at their docking position while the patient table can be repositioned independently. This segmentation allows patient repositioning without requiring undocking and repositioning of the robotic arms, maintaining surgical continuity.
2Adaptability or versatility
If robotic arms are undocked and repositioned, then patient repositioning is achieved, but surgical accuracy and instrument control precision are compromised
Solution Approach 1:
The system maintains the robotic arms in a fixed docking position while dynamically repositioning the patient table. The robotic arms remain stationary with their precision calibration intact, while the patient table moves to accommodate different surgical angles and positions, preserving both repositioning capability and instrument control precision.
3Adaptability or versatility
If multiple staff members manually reposition robotic arms and patient table, then patient repositioning is achieved, but operational complexity and time consumption increase
Solution Approach 1:
The system provides automated control where the surgeon can initiate patient repositioning through simple console commands. The control system automatically coordinates the patient table movement while maintaining robotic arm positions, eliminating the need for multiple staff members to manually manipulate the robotic arms and table, thereby reducing operational complexity.
4Adaptability or versatility
If robotic arms are repositioned frequently, then patient positioning flexibility is improved, but surgical efficiency and time management deteriorate
Solution Approach 1:
The system enables rapid, automated repositioning of the patient table without requiring robotic arm movement. The patient table can be quickly adjusted to different positions while the robotic arms remain docked and ready for immediate operation, significantly reducing the time required for position changes and improving surgical efficiency.
