Robotic Surgical System Motion Programming for Fatigue Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Minimally invasive surgery is burdensome for surgeons due to limitations in tool usage and the time-consuming process of tool changes, which can prolong surgical procedures and increase surgeon fatigue, especially when manually operating surgical controls for extended periods.
Innovation Solution
A system that acquires images of a surgical site, captures motion data of instruments, determines motion paths for robotic device components, and provides instructions for actuating these components along the determined paths, allowing for precise robotic assistance in surgical procedures, thereby reducing surgeon workload and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple tools are used during minimally invasive surgery, then surgical capability is improved, but tool change time increases
Solution Approach 1:
The robotic system integrates multiple surgical tools and functions into a single automated platform, allowing the robotic arm to perform various surgical tasks without requiring manual tool changes. The system can switch between different surgical instruments automatically, providing multi-functionality while eliminating time loss associated with manual tool changes.
Solution Approach 2:
The system pre-positions multiple surgical tools and prepares the robotic system in advance to perform sequential surgical tasks. By planning and preparing the surgical pathway and tool sequence beforehand, the system minimizes idle time and enables seamless transitions between different surgical operations.
2Measurement precision
If manual surgical controls are operated for long periods, then surgical precision can be maintained, but surgeon fatigue increases
Solution Approach 1:
The robotic system performs repetitive and time-consuming surgical tasks autonomously without requiring continuous manual intervention. The automated robotic arm executes pre-planned surgical pathways and maintains precision throughout the procedure, freeing the surgeon from prolonged manual control operations and reducing fatigue while preserving surgical accuracy.
Solution Approach 2:
The system replaces manual mechanical control with an automated robotic system that executes surgical tasks. The robotic platform substitutes the surgeon's hands for operating controls during extended periods, maintaining precision through automated control algorithms while eliminating the physical fatigue associated with prolonged manual operation.
3Ease of operation
If robotic automation is implemented, then surgeon fatigue is reduced, but system complexity increases
Solution Approach 1:
The robotic system is designed as a multi-functional platform that consolidates various surgical capabilities into a single integrated system. By providing multiple functions within one robotic platform, the system reduces the need for multiple separate devices and manual tool changes, thereby managing complexity while delivering comprehensive surgical automation.
