Hybrid Robotic Laparoscopic Surgery Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robotic surgery systems lack direct human contact with tissue, resulting in no true force feedback for surgeons and are expensive to manufacture, while also requiring extensive training due to the combination of mirrored and mimicked motion patterns during hybrid surgery procedures.
Innovation Solution
The development of hybrid surgical methods and devices that allow for the integration of both manually and robotically operated tools, enabling the use of electromechanical tools with electronic control systems to mimic motions and provide power motion assistance, and the use of adapters to convert manual instruments into robotically controlled ones, facilitating flexible operation modes and reducing the need for extensive training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If robotic systems are used to assist in MIS procedures, then more intuitive hand movements and more degrees of freedom in movement are achieved, but loss of direct human contact with tissue and no true force feedback occurs
Solution Approach 1:
The patent introduces a hybrid surgical system where a robotic arm acts as an intermediary to hold and position a surgical instrument, while a manual instrument passes through the same robotic arm to provide direct tactile feedback to the surgeon. This intermediary robotic structure enables both intuitive movement control and direct force feedback by allowing the surgeon to manipulate the manual instrument while the robotic arm maintains positioning stability.
2Ease of operation
If robotic systems are used to assist in MIS procedures, then more degrees of freedom in movement are achieved, but high expense to manufacture occurs
Solution Approach 1:
The patent creates a multi-functional system where a single robotic arm can operate in multiple modes: holding robotic instruments for fully automated procedures, holding manual instruments for hybrid procedures, or providing positional support while surgeons perform manual surgery. This universality allows the system to provide advanced degrees of freedom when needed while avoiding the expense of fully robotic systems for all procedures, as the same hardware serves multiple surgical approaches.
3Adaptability or versatility
If hybrid surgery using both manually and robotically operated tools is performed, then surgical flexibility is improved, but extensive training is required due to combination of mirrored and mimicked motion patterns
Solution Approach 1:
The patent implements a dynamic control system that can switch between mirrored motion mode and mimicked motion mode for the robotic arm. In mirrored mode, the robotic arm moves in the opposite direction of the controller (traditional robotic control). In mimicked mode, the robotic arm moves in the same direction as the controller (intuitive control). This dynamic switching capability allows surgeons to choose the motion pattern that best suits their skill level and comfort, reducing training requirements while maintaining surgical flexibility.
