Single-Piece Abdominal Hernia Mesh With Inguinal Flaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hernia mesh products do not provide full anatomical coverage during abdominal wall reconstruction, failing to reinforce the bilateral inguinal regions, which are often affected during such procedures, necessitating the use of multiple meshes and increasing the risk of hernia recurrence.
Innovation Solution
A single, anatomically configured hernia mesh that covers the entire abdominal wall, including the midline, lateral abdomen, and bilateral inguinal regions, with a unique shape comprising an upper convex section and a lower concave section with flaps to cover the inguinal areas, providing comprehensive reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single large sheet of mesh is used to cover the entire abdominal wall, then complete anatomical coverage is achieved, but the mesh lacks anatomic specificity and fails to reinforce the bilateral inguinal spaces
Solution Approach 1:
The mesh is divided into distinct anatomical regions including midline, lateral, and bilateral inguinal sections, each with specific structural features tailored to reinforce particular areas of the abdominal wall while maintaining coverage of the entire region
Solution Approach 2:
Different portions of the mesh are designed with varying structural properties - the inguinal regions receive specific reinforcement patterns while the midline and lateral sections have configurations optimized for their respective anatomical requirements, allowing each region to be reinforced according to its specific needs
2Reliability
If multiple meshes are used to cover the abdominal wall including inguinal regions, then complete reinforcement is achieved, but the device complexity and surgical procedure become more complicated
Solution Approach 1:
Multiple functional regions that would traditionally require separate mesh products are integrated into a single mesh structure, combining midline, lateral, and bilateral inguinal reinforcement capabilities in one piece, thereby maintaining comprehensive coverage and reinforcement while simplifying the surgical procedure to a single implantation step
3Ease of manufacture
If currently-available diamond-shaped mesh is used, then the mesh can be placed in the cavity for reinforcement, but it fails to support the bilateral inguinal spaces which are necessarily developed during flap dissection
Solution Approach 1:
The mesh design incorporates asymmetric features specifically adapted to match the anatomical configuration of the inguinal regions, with extended flaps and reinforced zones positioned to provide targeted support in these areas while maintaining overall placement simplicity

AI summary
A full coverage abdominal anatomic hernia mesh includes an upper mesh section, a lower mesh section, a lateral edge, and a horizontal axis. The lateral edge includes a first inflection point, an upper concave edge, a second inflection point, a lower-left concave edge, a third inflection point, a lower convex edge, a fourth inflection point, and a lower-right concave edge to define the preferred shape. The upper mesh section is adjacently connected to the lower mesh section along the horizontal axis. The lateral edge is perimetrically positioned around the upper mesh section and the lower mesh section. The upper concave edge is extended from the first inflection point to the second inflection point and adjacent to the upper mesh section. The lower-left concave edge, the third inflection point, the lower convex edge, the fourth inflection point, and the lower-right concave edge are positioned adjacent to the lower mesh section.
