Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional intestinal anastomosis methods, such as manual suturing and tubular staplers, face challenges like high operational difficulty, high incidence of anastomotic leakage, and limited applicability, especially during laparoscopic procedures, and fail to effectively prevent complications like leakage and stenosis.
Innovation Solution
An absorbable and unidirectional compressive intestinal anastomosis device comprising two interlocking pipe portions with expandable elastic horn-shaped openings and tooth-shaped structures for secure fixation, allowing for easy alignment and end-to-end anastomosis, suitable for a wider range of intestinal applications, including laparoscopic surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual suture method is used, then the anastomosis can be performed with basic surgical tools, but the operational difficulty is high and the incidence of anastomotic leakage is high
Solution Approach 1:
The patent introduces a specialized anastomosis device as an intermediary tool between the surgeon and the intestinal ends. This device includes alignment guides, clamping mechanisms, and suturing aids that facilitate the anastomosis process without requiring highly complex surgical techniques, thereby reducing operational difficulty while maintaining effectiveness
Solution Approach 2:
The device performs preliminary actions by pre-aligning the intestinal ends using guide structures and clamping mechanisms before the actual suturing begins. This preliminary alignment and securing of tissue edges simplifies the subsequent suturing process and reduces the skill level required while minimizing leakage risk
2Productivity
If tubular stapler is used, then the anastomosis speed is improved, but the applicability range is limited and additional small opening suturing is required
Solution Approach 1:
The patent designs a multi-functional anastomosis device that can accommodate different intestinal diameters and locations through adjustable components and interchangeable attachments. The device integrates alignment, clamping, and suturing functions in one system, eliminating the need for additional small opening suturing required by tubular staplers and expanding applicability across various intestinal regions
3Productivity
If traditional anastomosis methods are used, then the surgical procedure can be completed, but the operation time is prolonged and the difficulty of laparoscopic anastomosis is high
Solution Approach 1:
The patent divides the anastomosis process into distinct modular steps using a segmented device structure with separate alignment, clamping, and suturing components. This segmentation allows each function to be performed systematically and independently, reducing overall operation time and making the procedure more manageable in laparoscopic settings where precision and control are challenging

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device simplifies the anastomosis process, reduces the incidence of leakage, ensures accurate alignment, and shortens operation time, making it suitable for both open and laparoscopic surgeries across various intestinal regions with a high success rate and minimal tissue disruption.

AI summary
An absorbable and unidirectionally compressible intestinal anastomosis device, including a first through pipe portion and a second through pipe portion respectively including large ends and small ends; the large ends are used for fixing an intestinal canal; and the small end of the second through pipe portion is inserted into the small end of the first through pipe portion. The two large ends are drawn close to each other to achieve an intestine-intestine anastomosis. The outer sides of circular rings at the ends of the small ends of the first through pipe portion and the second through pipe portion are provided with gradually-expanded elastic horn-shaped openings. The device can make two stapled intestinal canals rest relatively, thereby avoiding adjustments required in other assembling modes.
