Disposable Reusable Endoscope Assembly for Embryo Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current visual endoscopes for abortion procedures lack high-resolution visualization and illumination, leading to potential damage to non-embryonic mucosal layers and increased risk of medical disputes due to inaccurate embryo positioning and post-operative cavity observation.
Innovation Solution
A visualized surgical assembly comprising a disposable drainage tube and a reusable functional tube with a visualization head, connected via a sliding chute-slider mechanism, featuring a self-destructive cutting mechanism to prevent reuse and equipped with a photoelectric conversion module and lighting system for enhanced visualization and illumination, allowing for accurate embryo positioning and reduced tissue trauma.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a disposable plastic drainage tube with camera is used, then the cost is reduced and sterilization is simplified, but the image resolution and illumination brightness are insufficient for accurate embryo positioning and post-operative cavity observation
Solution Approach 1:
The drainage tube system is segmented into disposable and reusable parts. The disposable plastic drainage tube handles sterilization and single-use disposal, while the reusable metal drainage tube provides high-resolution camera and lighting components that can be sterilized and reused, combining the advantages of both approaches
Solution Approach 2:
The patent merges disposable and reusable components into a hybrid system. The disposable plastic drainage tube is connected to the reusable metal drainage tube, allowing the system to benefit from both the ease of disposable sterilization and the high-quality imaging capabilities of reusable components
2Measurement precision
If a reusable metal drainage tube is used, then the image resolution and illumination are improved, but the cost increases and sterilization complexity increases
Solution Approach 1:
The system separates sterilization requirements by segmenting the drainage tube into disposable and reusable portions. The disposable plastic tube eliminates the need for complex sterilization procedures for the imaging components, as only the reusable metal tube requires sterilization, which can be performed using standard medical sterilization protocols
Solution Approach 2:
The disposable plastic drainage tube serves as a low-cost, single-use component that protects the expensive reusable imaging system from contamination, eliminating the need for complex sterilization of the camera and lighting components while maintaining high image quality
3Measurement precision
If a visual endoscope is used for embryo positioning, then the accuracy of embryo location is improved, but the ability to observe post-operative cavity conditions is compromised due to lack of fluid perfusion capability
Solution Approach 1:
The drainage tube system is designed with multi-functionality to perform both embryo positioning and post-operative cavity observation. The detachable design allows the same system to be used for suction during the procedure and for fluid perfusion with camera observation afterward, eliminating the need for separate devices
Solution Approach 2:
The system dynamically adapts its function during the surgical procedure. The drainage tube can be configured for suction mode during embryo removal and then reconfigured for fluid perfusion and observation mode post-operatively, providing versatility throughout different stages of the surgical process
4Device complexity
If the drainage tube is designed as a single integrated unit, then the structure is simple, but the risk of cross-infection increases and reuse is not possible
Solution Approach 1:
The drainage tube is segmented into disposable and reusable sections with a detachable connection. This segmentation allows the disposable portion to be discarded after single use, eliminating cross-infection risk, while the reusable portion can be sterilized and used multiple times, maintaining structural functionality without compromising safety
Solution Approach 2:
The disposable plastic drainage tube is extracted as a separate, removable component from the reusable metal drainage tube. This extraction allows the disposable portion to be easily removed and discarded after use, preventing cross-infection while maintaining the functionality of the reusable imaging components
