Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical mesh application methods require multiple steps and tools for placement and securing, which can be cumbersome and inefficient, especially in minimally invasive surgeries.
Innovation Solution
A semi-cylindrical applicator with a roller assembly and a surgical mesh roll having an adhering side with tissue-engaging barbs and a non-adhering side with adhesive strips, allowing for simultaneous application and securement of the mesh to tissue without the need for additional fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional surgical mesh application methods are used, then the mesh can be applied to tissue, but the process requires multiple steps and tools making it cumbersome and inefficient
Solution Approach 1:
The patent combines the surgical mesh and applicator into a single integrated assembly where the mesh is pre-positioned within the applicator body. This merging eliminates the need for separate steps to insert and position the mesh, allowing the surgeon to apply the complete assembly in a single motion, thereby improving productivity while reducing procedural complexity
Solution Approach 2:
The surgical mesh is pre-positioned and prepared within the applicator before the surgical procedure. The mesh is already configured with adhering surfaces and non-adhering surfaces in the correct orientation, eliminating the need for real-time positioning and configuration during surgery, thus streamlining the application process
2Reliability
If multiple surgical fasteners are used to secure the mesh, then the mesh can be firmly attached to tissue, but the number of steps and tools required increases
Solution Approach 1:
The surgical mesh incorporates self-adhering properties with adhering surfaces that automatically bond to the tissue upon contact. The mesh design includes interlocking structures and adhesive elements that enable the mesh to secure itself to the tissue without requiring external fasteners or additional surgical tools, thereby maintaining attachment security while significantly simplifying the operation
Solution Approach 2:
The patent removes the need for separate surgical fasteners (such as staples, clips, or tacks) by integrating the fastening function directly into the mesh structure itself. The mesh contains built-in adhering elements that perform the fastening function, eliminating the need for additional tools and steps
3Reliability
If a surgical fastener applier is inserted to affix the mesh, then the mesh can be secured to tissue, but the number of instruments and procedural steps increases
Solution Approach 1:
The patent merges the mesh and applicator into a single integrated instrument assembly. The applicator body is designed to contain and position the mesh, and the entire assembly is inserted through a single incision site, eliminating the need for separate insertion of the mesh and separate insertion of a fastener applier, thus reducing the number of instruments while maintaining fixation reliability
Solution Approach 2:
The applicator is designed as a multi-functional device that simultaneously performs multiple functions: it serves as the delivery vehicle for the mesh, provides positioning guidance, and facilitates the attachment process. This universal design eliminates the need for multiple specialized instruments, reducing overall device complexity

AI summary
A surgical repair device is provided and includes a roll (12) of surgical mesh material and an applicator (10) for applying the roll of surgical mesh material to tissue. The applicator has a generally cylindrical body portion (14) defining a chamber for receipt of the roll of surgical mesh material and longitudinally extending edges (24, 26) defining a gap (28) therebetween for exposing the roll of surgical mesh material to the tissue. The surgical mesh material has a non-adhering surface (72) and an adhering surface (70) for engaging the tissue and securing the surgical mesh to the tissue. The roll of mesh material is oriented within the chamber with the adhering surfacing outward. A method of using the surgical repair device to repair a tear in tissue is also provided.
