Vaginal Occlusion Device Sealing Laparoscopic Gas Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During laparoscopic surgery, maintaining pneumoperitoneum through the vagina is challenging due to gas leakage and anatomical variations in women, which complicates surgical exposure and device usage.
Innovation Solution
A vaginal occlusion device with a shaft and handle, featuring a non-latex, medical-grade head that can be inserted into the vagina to prevent gas leakage, designed to fit various anatomies with adjustable handle configurations and shapes to ensure effective sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the vagina is used as a route for natural orifice extraction, then the surgical procedure becomes less invasive, but gas escapes through the vaginal opening making it difficult to maintain surgical exposure
Solution Approach 1:
A vaginal occlusion device is introduced as an intermediary element between the abdominal cavity and the vaginal opening. The device includes a balloon that can be inflated to seal the vaginal cuff, preventing gas escape while allowing the vagina to remain open for specimen extraction. This mediator resolves the conflict between maintaining pneumoperitoneum and enabling natural orifice extraction.
Solution Approach 2:
The occlusion device is deployed in advance to prevent the harmful effect of gas leakage before it compromises surgical exposure. By placing the occlusion device and inflating the balloon prior to or during the extraction process, the system proactively counteracts the tendency for gas to escape through the vaginal opening, thereby maintaining stable pneumoperitoneum throughout the procedure.
2Adaptability or versatility
If various sized surgical devices are used to accommodate anatomical variations, then the device can fit different patients, but the device complexity increases
Solution Approach 1:
The occlusion device incorporates a balloon that can be dynamically adjusted in size by controlling the inflation volume. This allows a single device design to adapt to different vaginal cuff dimensions and patient anatomies. The balloon expands to fill the available space, providing an effective seal regardless of the specific anatomical variations, thereby eliminating the need for multiple pre-sized devices.
Solution Approach 2:
The device utilizes changes in the physical parameter of balloon volume to accommodate anatomical variations. By adjusting the amount of fluid or gas injected into the balloon, the occlusion device can be customized in real-time to fit different patient anatomies. This parameter adjustment approach simplifies the device design compared to manufacturing multiple devices with fixed sizes.
