Solution Overview
Problem
Current surgical stapling and cutting instruments face challenges in efficiently stapling and cutting tissue due to variations in tissue thickness and properties, leading to inconsistent results and potential tissue over-compression.
Innovation Solution
The implementation of a surgical stapling and severing instrument with a staple cartridge that includes a compressible tissue thickness compensator and an implantable layer, which are securely attached to the cartridge deck using a bonding layer, allowing for adjustable attachment regions to manage tissue compression and promote tissue ingrowth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a compressible tissue thickness compensator is used to manage tissue compression, then consistent tissue compression is achieved, but device complexity increases
Solution Approach 1:
The compressible tissue thickness compensator is integrated within the staple cartridge assembly, nested between the cartridge deck and the anvil. This nesting approach allows the compensator to be incorporated into the existing surgical instrument without requiring separate external components, thereby managing tissue compression consistency while minimizing the increase in overall device complexity.
Solution Approach 2:
The compressible tissue thickness compensator utilizes material with specific compressible properties that allow it to adapt to varying tissue thicknesses. By changing the physical state and compressibility parameters of the compensator material, the system achieves consistent tissue compression across different tissue types and thicknesses without requiring complex mechanical adjustment mechanisms.
2Reliability
If an implantable layer with bonding layer is used to promote tissue ingrowth, then healing is promoted, but device complexity increases
Solution Approach 1:
The implantable layer with bonding properties is merged with the tissue thickness compensator to create a multi-functional component. This integration combines the tissue ingrowth promotion function with the tissue compression management function in a single layered structure, thereby promoting healing while minimizing the increase in device complexity through functional consolidation.
Solution Approach 2:
The implantable layer utilizes composite material structure with bonding characteristics that facilitate tissue ingrowth. By employing composite materials with specific surface properties and bonding capabilities, the system promotes reliable healing and tissue integration without requiring complex biological or chemical systems, thus maintaining relative device simplicity.
3Object-affected harmful factors
If adjustable attachment regions are used to manage tissue compression, then tissue over-compression risk is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The attachment regions of the compressible tissue thickness compensator are designed with local quality variations, where specific zones have different bonding characteristics or attachment capabilities. This local differentiation allows the compensator to provide adjustable attachment at specific locations while maintaining overall compression consistency, thereby reducing over-compression risk without requiring extreme manufacturing precision across the entire component.
