Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anastomosis techniques for joining blood vessels are time-consuming, requiring significant time to suture multiple vessels, which necessitates an improved method to reduce the time required for vascular anastomosis.
Innovation Solution
An anastomosis set comprising a first and second manipulator with telescoping parts and an anastomosis mechanism, including a suture mechanism, clamping mechanism, and anastomotic auxiliary devices that facilitate efficient alignment and joining of blood vessel ends, allowing for rapid and secure anastomosis with easy removal and potential bioabsorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional suture techniques are used to join blood vessels, then the anastomosis can be securely completed, but the procedure takes a significant amount of time
Solution Approach 1:
The anastomosis device is divided into multiple functional segments including telescoping parts for alignment, manipulators for vessel handling, and an anastomosis mechanism for joining. This segmentation allows each component to perform its specific function efficiently, reducing overall procedure time while maintaining secure anastomosis
Solution Approach 2:
The patent introduces an intermediate anastomosis mechanism that acts as a mediator between the two blood vessel ends. This mechanism includes alignment features and joining components that facilitate secure connection without requiring time-consuming traditional suturing techniques
2Reliability
If multiple blood vessels are sutured, then complete vascular reconstruction is achieved, but the total surgical time increases significantly
Solution Approach 1:
The anastomosis device is designed as a universal tool that can be applied to multiple different blood vessels throughout the surgical procedure. The device performs multiple functions including alignment, clamping, and anastomosis in a single integrated system, enabling efficient reconstruction of numerous vessels without requiring multiple different surgical instruments
Solution Approach 2:
The device incorporates preliminary alignment features through telescoping parts and manipulators that prepare the blood vessel ends for joining before the actual anastomosis occurs. This preliminary positioning and alignment is performed automatically by the device structure, eliminating time-consuming manual preparation for each vessel connection
3Manufacturing precision
If telescoping parts are extended to align blood vessel ends, then precise alignment is achieved, but the device complexity increases
Solution Approach 1:
The telescoping parts are designed with nested structures where one telescoping segment is contained within another. This nesting arrangement allows for precise alignment through multiple stages of extension while maintaining a compact form factor. The manipulators themselves are nested within the overall device structure, reducing external complexity while providing sophisticated alignment capabilities
