Detachable Separation Member for Easier Tissue Stripping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical instruments face difficulties in efficiently separating target tissues, such as blood vessels, from surrounding tissues due to inadequate design of the end effector, requiring laborious adjustments to align and separate the target tissue for cutting and suturing.
Innovation Solution
A detachable separation member with a mounting portion and a working portion, featuring a clipping mechanism and elastic connection, allows for easy attachment and detachment to the surgical instrument, facilitating the stripping of target tissues from other tissues before cutting and suturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional end effector design is used, then the surgical instrument can perform basic cutting and suturing functions, but it requires laborious adjustments and repeated angle changes to separate target tissue from surrounding tissue
Solution Approach 1:
The end effector is divided into distinct functional components: a separation member with separating edges for detaching target tissue, a staple cartridge for suturing, and a cutting component. This segmentation allows each component to perform its specific function optimally without requiring repeated adjustments of a unified structure.
Solution Approach 2:
The separation member is positioned at the distal end of the end effector to perform preliminary separation of target tissue from surrounding tissue before the staple cartridge and cutting component are activated. This preliminary action prepares the tissue in advance, eliminating the need for repeated angle adjustments during the suturing and cutting phases.
2Ease of operation
If the conventional end effector design is used, then the surgical instrument structure remains simple, but the doctor must repeatedly adjust the angle and apply force to separate target tissue
Solution Approach 1:
The separation member, staple cartridge, and cutting component are merged into a single integrated end effector assembly that can be operatively supported relative to the staple cartridge base. This merging provides the separating function without requiring a completely separate device, thus limiting the increase in overall system complexity.
Solution Approach 2:
The end effector is designed with movable components that can be actuated in sequence: the separation member first detaches the target tissue, then the staple cartridge sutures, and finally the cutting component cuts. This dynamic sequencing of functions allows the separation capability to be added without permanently increasing structural complexity.
3Adaptability or versatility
If the far end of the end effector is designed for basic functions, then the overall instrument design remains straightforward, but it is not suitable for stripping target tissue from surrounding tissue
Solution Approach 1:
The separation member is designed with specific local qualities: two opposing separating edges that can detach target tissue from surrounding tissue. This localized specialization of the distal end of the end effector provides tissue stripping capability without requiring the entire instrument to be redesigned for this specific function.
