Transparent Morcellation Bag Single Port Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laparoscopic morcellation bags face challenges such as complex insertion procedures, risk of contamination, and reduced visibility during surgical interventions, particularly in hysterectomy and myomectomy, due to design flaws like multiple ports and perforation requirements, which increase intervention time and morbidity risks.
Innovation Solution
A laparoscopic morcellation bag with a transparent region made of materials with high total transmittance, clarity, and low haze, allowing optical devices to maintain direct contact without perforation, combined with a single port design and leak-tight valves, facilitating easier insertion and extraction while minimizing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple ports are provided in the morcellation bag, then optical devices and insufflation devices can be introduced, but the insertion procedure becomes complex and intervention time increases
Solution Approach 1:
The patent combines multiple ports into a single integrated port structure. The single port allows simultaneous introduction of optical devices, insufflation devices, and the morcellator through one unified access point, eliminating the need for multiple separate incisions and reducing procedural complexity while maintaining all necessary functional capabilities
Solution Approach 2:
The single port is designed as a universal access point that can accommodate multiple different instruments simultaneously. It includes multiple lumens or channels within the single port structure, allowing optical devices, insufflation catheters, and morcellation instruments to pass through the same external incision, thereby reducing the number of skin punctures required
2Illumination intensity
If the bag wall is perforated to introduce optical devices, then direct viewing is possible, but contamination risk increases
Solution Approach 1:
The patent uses the single port as an intermediary structure that allows optical devices to access the intraperitoneal space without requiring perforation of the bag wall itself. The port acts as a sealed gateway through which cameras and light sources can be introduced while maintaining the integrity and sterility of the bag enclosure, thus enabling visualization while preventing contamination
Solution Approach 2:
The single port is designed as a disposable component that is discarded after a single use. This eliminates the need to sterilize or reprocess the port between uses, and ensures that any potential contamination is contained to a single-use element rather than risking contamination of reusable instruments through wall perforation
3Ease of operation
If a single port design is used, then insertion and extraction are simplified, but visibility during morcellation may be reduced
Solution Approach 1:
The single port is segmented into multiple internal lumens or channels, each capable of accommodating different instruments. This segmentation allows multiple optical devices (such as cameras and light sources) to be introduced through the same external port, providing comprehensive visualization of the morcellation process while maintaining the simplicity of a single external incision
Solution Approach 2:
The patent transitions from a two-dimensional view (single camera angle) to a three-dimensional visualization capability by introducing multiple optical devices through the single port. This allows for多角度 (multi-angle) viewing and stereoscopic imaging, enhancing visibility and spatial awareness during morcellation while still using only one external access point
Applied Scientific Principles
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 solution reduces intervention time, minimizes contamination risks, and enhances visibility during and after morcellation, thereby improving surgical efficiency and safety by providing a continuous view of the abdominal cavity without blind spots.
