Endoscopic Suture Device with Deployable Anchors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscopic procedures lack the capability to effectively close tissue defects within body passages due to the limitations of existing endoscopes, which do not possess intrinsic treatment capabilities, leading to inefficiencies and increased risk of infection from reusable scopes.
Innovation Solution
Development of endoscopic suturing devices with elongate members having working and suture channels, equipped with deployable anchor components that expand from a collapsed to an expanded configuration, facilitated by a delivery device within the suture channel, allowing for secure engagement and closure of tissue defects through various suturing patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional endoscopes are used for tissue closure, then the procedure can be performed with existing equipment, but the endoscope lacks intrinsic treatment capability and cannot effectively close tissue defects
Solution Approach 1:
The patent merges the endoscope with integrated treatment capabilities by incorporating a delivery device, anchor components, and suture mechanisms directly into the endoscope structure. This allows the endoscope to perform both visualization and tissue closure functions, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The endoscope is designed with multi-functionality to serve both diagnostic and therapeutic purposes. The integrated delivery device and anchor components enable the same device to perform tissue closure procedures that would otherwise require separate specialized instruments, thereby improving versatility without proportionally increasing complexity.
2Object-affected harmful factors
If reusable endoscopes are used, then cost is reduced, but the risk of infection increases
Solution Approach 1:
The patent enables the use of disposable endoscopes with integrated treatment capabilities. By making the entire endoscope system disposable rather than reusable, the infection risk is eliminated while the cost is managed through the single-use model. This resolves the contradiction by prioritizing patient safety over cost savings.
3Reliability
If anchor components are deployed outside the body, then tissue closure can be achieved, but the risk of infection from reusable scopes increases
Solution Approach 1:
The disposable endoscope design ensures that the anchor components and delivery devices are single-use only. This eliminates the infection risk associated with reusable scopes while maintaining secure tissue closure through the anchor mechanism. The disposable nature guarantees reliability without compromising safety.
4Productivity
If complex suturing patterns are used, then effective tissue closure is achieved, but the procedure complexity increases
Solution Approach 1:
The delivery device is designed to automatically deploy anchor components and suture materials without requiring complex manual manipulation. The system performs the suturing actions autonomously based on simple operator inputs, thereby achieving effective tissue closure with reduced procedure complexity and improved productivity.
