Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robotic tele-surgery systems face high maintenance and operational costs due to the need for single- or limited-use robotic appliances and exclusive surgical instruments, limiting their accessibility and affordability.
Innovation Solution
A tool adapting device that connects and activates manual laparoscopic surgical instruments on a robotic surgery arm, enabling the use of non-exclusively designed, cost-effective instruments by providing an attachment interface and a mechanism to control degrees of freedom such as grasp, roll, pitch, and yaw, allowing for the integration of manual surgical instruments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If integrated and exclusively designed surgical instruments are used in robotic tele-surgery systems, then surgical precision and system integration are improved, but operational costs and maintenance expenses increase significantly
Solution Approach 1:
The adapter assembly enables a single robotic arm to interface with multiple types of surgical instruments (both robotic and manual laparoscopic instruments), making the system universal. This allows the system to perform multiple functions using different instruments while maintaining surgical precision through the adapter's ability to control all degrees of freedom for various instrument types
Solution Approach 2:
The adapter assembly acts as an intermediary component between the robotic arm and manual laparoscopic surgical instruments. It mediates the connection and controls the interface, allowing manual instruments to be used with robotic precision by translating robotic arm movements into corresponding instrument movements while maintaining surgical accuracy
2Reliability
If single- or limited-use robotic appliances are used, then surgical accuracy is maintained, but maintenance costs and operational expenses increase
Solution Approach 1:
The adapter assembly enables the use of disposable or limited-use manual laparoscopic surgical instruments instead of expensive robotic instruments. These manual instruments can be discarded or sterilized between uses, reducing maintenance costs while the adapter ensures surgical accuracy is maintained through precise control of all degrees of freedom
Solution Approach 2:
The system is segmented into modular components: the robotic arm, the adapter assembly, and interchangeable surgical instruments. This segmentation allows the expensive robotic arm to be used with multiple different instruments through the adapter, reducing the need for multiple specialized robotic appliances and thereby reducing overall maintenance costs
3Productivity
If manual laparoscopic surgical instruments are integrated with robotic surgery arm, then cost-effectiveness and accessibility are improved, but control precision and manipulation accuracy may be compromised
Solution Approach 1:
The adapter assembly serves as an intermediary that translates robotic arm movements into precise control of manual surgical instruments. It maintains control precision by controlling all degrees of freedom (grasp, roll, pitch, yaw) of the manual instruments, ensuring that the lower cost of manual instruments does not compromise surgical accuracy
Solution Approach 2:
The adapter assembly changes the control parameters by translating robotic arm movements into corresponding movements of the manual instrument. It controls the grasp, roll, pitch, and yaw parameters of the manual instrument to match the intended surgical motion, maintaining precision despite the difference in instrument types
4Reliability
If expensive robotic surgical instruments are used, then surgical outcomes are improved, but accessibility and affordability of robotic tele-surgery systems decrease
Solution Approach 1:
The adapter assembly makes robotic tele-surgery systems universal by enabling them to work with both expensive robotic instruments and affordable manual laparoscopic instruments. This increases accessibility and affordability while maintaining surgical outcomes through precise control of the manual instruments via the adapter
Solution Approach 2:
The adapter assembly acts as an intermediary that allows affordable manual instruments to achieve robotic-level surgical outcomes. It mediates between the robotic arm's precise control capabilities and the manual instrument's mechanical actions, ensuring surgical outcomes are improved while maintaining affordability
