Fibrin Pad Matrix with Heat-Activated Glue Beads for Tissue Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical staplers used in endoscopic procedures face challenges in effectively sealing and repairing tissue due to issues with staple formation and bleeding, as they often require additional haemostatic agents and adhesives that are not efficiently integrated into the stapling process.
Innovation Solution
A surgical stapling and severing instrument with an articulating end effector that includes a fibrin pad matrix with heat-activated glue beads, which are driven into the tissue along with staples to provide immediate adhesion and hemostasis, reducing bleeding and enhancing tissue repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical staplers use traditional stapling method, then staple formation is achieved, but tissue sealing and hemostasis are insufficient
Solution Approach 1:
The patent combines stapling, adhesive application, and hemostatic agent delivery into a single integrated surgical instrument. The stapler simultaneously drives staples into tissue while applying adhesive from a cartridge and delivering hemostatic agents, merging multiple functions that were previously performed by separate devices or manual steps.
Solution Approach 2:
The instrument applies adhesive and hemostatic agents to the tissue before or during the stapling process. The adhesive is pre-loaded in the cartridge and positioned to be applied at the moment of stapling, ensuring immediate tissue sealing and preparation for hemostasis before the staples fully secure the tissue.
2Reliability
If additional haemostatic agents and adhesives are applied separately, then tissue repair is enhanced, but surgical process complexity increases
Solution Approach 1:
The surgical stapler is designed as a multi-functional device that performs stapling, adhesive application, and hemostatic agent delivery through a single instrument. The cartridge system integrates multiple adhesive sources and hemostatic agents, allowing the device to perform multiple tissue repair functions without requiring separate instruments or manual application steps.
Solution Approach 2:
The patent merges the functions of stapling, adhesive application, and hemostatic delivery into one integrated system. The cartridge contains both adhesive material and hemostatic agents, and the firing mechanism simultaneously deploys staples and releases these auxiliary substances, simplifying the surgical workflow despite the enhanced functionality.
3Reliability
If adhesive is applied to saturate the entire buttress, then adhesion coverage is maximized, but material consumption increases
Solution Approach 1:
The patent employs multiple adhesive cartridges positioned at different locations within the stapler, each targeting specific regions of the tissue or buttress. Rather than applying adhesive uniformly across the entire surface, the system delivers adhesive locally to areas where it is most needed, optimizing adhesion coverage while reducing overall material consumption.
Solution Approach 2:
The adhesive application system is divided into multiple separate cartridges, each containing adhesive for specific purposes or locations. This segmentation allows selective application of adhesive to different areas of the tissue interface, ensuring adequate coverage without saturating the entire buttress surface and wasting material.

AI summary
A surgical instrument includes a handle portion, a shaft housing a firing bar, an end effector comprising an anvil, a lower jaw, and a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft. The lower jaw is configured to receive a cartridge when in an open position. The cartridge includes a housing, a plurality of staples disposed in the housing, and a deck disposed over the plurality of staples. The deck defines apertures, with each aperture being substantially disposed over each staple. The cartridge further receives a matrix including glue beads suspended in the matrix. The staples are driven through the matrix to secure the matrix to tissue. The glue beads are activated when the matrix is secured to the tissue, such that the activated adhesive further secures the staple line in the tissue.
