Implantable Staple Adjunct Structure for Full Retainer Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing staple cartridges face issues with incomplete splitting of implantable adjuncts during retainer removal, leading to procedural interruptions and increased duration due to interference between connections and center rib extensions.
Innovation Solution
Incorporating a retainer with a center rib extension having a sharp edge and an implantable adjunct with a knife slot featuring a plurality of slits and transverse cuts to ensure full cutting of the adjunct into two halves during retainer removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a burr-free cut is attempted by adjusting cutting parameters, then cut quality improves, but total reaming time increases due to multiple pass requirements
Solution Approach 1:
The method performs a preliminary assessment of burr formation risk before the actual reaming operation. By evaluating material properties, tool characteristics, and cutting parameters in advance, the system determines whether a single pass will achieve burr-free cutting, allowing operators to optimize parameters for one-pass operation when conditions permit
Solution Approach 2:
The system incorporates feedback mechanisms that monitor cutting conditions and burr formation in real-time. This feedback allows dynamic adjustment of cutting parameters during operation and provides data for optimizing future reaming operations, enabling the system to learn from each operation and improve efficiency over time
2Manufacturing precision
If multiple reaming passes are used to ensure burr-free cuts, then cut quality improves, but manufacturing complexity increases
Solution Approach 1:
The method performs a preliminary assessment of burr formation risk before the actual reaming operation. By evaluating material properties, tool characteristics, and cutting parameters in advance, the system determines whether a single pass will achieve burr-free cutting, allowing operators to optimize parameters for one-pass operation when conditions permit
Solution Approach 2:
The system systematically varies cutting parameters such as speed, feed rate, and depth of cut based on evaluated conditions. By optimizing these parameters for single-pass operation when possible, or for specific pass configurations when necessary, the method reduces process complexity while maintaining quality standards
3Manufacturing precision
If conservative cutting parameters are used to prevent burrs, then cut quality improves, but cutting speed decreases
Solution Approach 1:
The system systematically varies cutting parameters such as speed, feed rate, and depth of cut based on evaluated conditions. By optimizing these parameters for single-pass operation when possible, or for specific pass configurations when necessary, the method reduces process complexity while maintaining quality standards
Solution Approach 2:
The system incorporates feedback mechanisms that monitor cutting conditions and burr formation in real-time.
