Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for introducing auxiliary medical materials into surgical areas, such as during hernia operations, are complex and risk damaging the materials due to manual rolling or folding and insertion through trocar sleeves.
Innovation Solution
A device featuring a hollow application tube with a winding insert that allows for the winding and insertion of auxiliary medical materials without manual rolling, enabling safe and simple application by rotating components and using slits for affixing the material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual rolling or folding is used to insert auxiliary medical material into the trocar sleeve, then the material can be introduced into the surgical area, but the complexity of operation increases and the risk of damaging the material increases
Solution Approach 1:
The patent introduces a trocar sleeve as an intermediary device that pre-formed auxiliary medical material can be inserted into. The sleeve acts as a protective conduit that eliminates the need for manual rolling or folding of the material during insertion, thereby reducing operational complexity while maintaining ease of insertion. The sleeve is designed to receive pre-prepared material and transport it directly to the surgical site.
2Ease of manufacture
If manual rolling or folding is used to prepare auxiliary medical material, then the material can be inserted into the trocar sleeve, but the risk of damaging the material increases
Solution Approach 1:
The patent implements preliminary action by pre-forming the auxiliary medical material into a configuration suitable for insertion into the trocar sleeve before the surgical procedure. The material is prepared in advance with attachment means (such as sutures or clips) already in place, eliminating the need for manual rolling or folding during the procedure. This preliminary preparation ensures material integrity by avoiding handling and manipulation that could cause damage.
3Ease of operation
If a winding insert is used to wind up auxiliary medical material, then manual rolling is eliminated, but the device complexity increases
Solution Approach 1:
The patent applies self-service through the winding insert mechanism, which automatically winds the auxiliary medical material around itself as the material is fed through the trocar sleeve. The insert is designed with a geometry that causes the material to wrap around it naturally during insertion, eliminating the need for manual rolling while keeping the device structure relatively simple. The self-winding action reduces the need for complex mechanical winding mechanisms.
