Laparoscopic Hernia Repair Device with Collapsible Mesh
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parietal surgery methods for hernia repair, especially laparoscopic procedures, face challenges due to the lack of direct 'hands-on' contact, which can make them less accessible and more awkward for surgeons, and the need for improved devices to securely deploy and expand surgical meshes within the abdominal cavity.
Innovation Solution
A device comprising a body with a collapsible parietal surgical implant that can be expanded using a sleeve and actuator system, allowing for precise deployment and securement of a mesh against the hernia site, facilitating hernia repair with reduced scarring and recovery time.

Engineering Contradiction Analysis
1Length of moving object
If a collapsible parietal surgical implant is used, then the device can be inserted through a small incision for minimally invasive surgery, but the implant must be expanded and deployed accurately at the target site
Solution Approach 1:
The parietal surgical implant is collapsed into a compact configuration that fits within the device body, allowing insertion through a small incision. The implant is then expanded at the target site to its full operational size, enabling minimally invasive surgery while maintaining deployment precision.
Solution Approach 2:
The device incorporates an expansion mechanism that allows the parietal surgical implant to transition from a collapsed state during insertion to an expanded state at the target site. This dynamic transformation enables the implant to be delivered through a small incision and then deployed to the correct size and shape for effective hernia repair.
2Loss of time
If laparoscopic surgery is performed without direct hands-on contact, then recovery time is reduced and scarring is minimized, but the surgical procedure becomes more awkward and less accessible to surgeons
Solution Approach 1:
The device serves as an intermediary tool between the surgeon and the parietal surgical implant. It provides mechanical guidance and positioning assistance, making the laparoscopic procedure more manageable and accessible to surgeons while maintaining the benefits of minimally invasive surgery with reduced recovery time and scarring.
Solution Approach 2:
The device incorporates features that enable self-positioning and self-deployment of the parietal surgical implant at the target site. The expansion mechanism and retention features allow the implant to automatically secure itself, reducing the need for complex manual manipulation and making the procedure more accessible to surgeons.
3Reliability
If a mesh implant is used to reinforce the abdominal wall, then hernia repair effectiveness is increased, but the device complexity increases
Solution Approach 1:
The device is divided into distinct functional segments: a delivery mechanism for insertion, an expansion mechanism for deploying the mesh implant, and retention features for securing it in place. This segmentation allows each component to perform its specific function efficiently while maintaining overall device manageability and reducing unnecessary complexity.
Solution Approach 2:
The device body serves multiple functions: it acts as a protective sheath during insertion, provides a mounting structure for the parietal surgical implant, and facilitates the expansion and deployment process. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity while maintaining hernia repair effectiveness.
4Ease of operation
If the parietal surgical implant is retained within the body in collapsed state, then the device can be manipulated and positioned accurately, but the implant must be exposed and deployed precisely
Solution Approach 1:
The device incorporates a dynamic exposure mechanism that allows the parietal surgical implant to be revealed from its collapsed state within the device body. The expansion and exposure actions are coordinated to ensure precise deployment at the target site while maintaining ease of manipulation during the surgical procedure.
