Surgical Stapling Device with Patterned Therapeutic Buttress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical stapling instruments lack effective means to deliver therapeutic agents directly to tissue sites during procedures and provide insufficient reinforcement and sealing of staple lines.
Innovation Solution
A surgical stapling device with pivotally coupled anvil and cartridge assemblies, featuring buttresses with therapeutic agents applied in specific patterns to enhance tissue repair and delivery, including chemotherapy drugs combined with excipients, attached via sutures for targeted treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If surgical stapling instruments are used to join tissue segments, then tissue joining is achieved, but the ability to deliver therapeutic agents to the treatment site is insufficient
Solution Approach 1:
The patent combines the therapeutic agent delivery function with the existing stapling instrument by integrating a reservoir containing therapeutic agent into the stapling device. The reservoir is positioned to allow delivery of the therapeutic agent directly to the tissue site during the stapling procedure, merging two functions (tissue joining and drug delivery) into a single integrated system.
Solution Approach 2:
The surgical stapling instrument is designed to perform multiple functions: it can apply staples to join tissue segments, cut tissue with an optional knife blade, and deliver therapeutic agents through the integrated reservoir. This multi-functional design allows a single device to address multiple surgical needs without requiring separate instruments.
2Strength
If staple lines are applied to join tissue, then tissue joining is achieved, but reinforcement and sealing of staple lines is insufficient
Solution Approach 1:
The patent incorporates a buttress material attached to the anvil that is applied to the tissue before the staples are driven. This preliminary placement of the buttress provides immediate reinforcement and sealing support to the staple line as the staples are formed, enhancing the structural integrity of the joined tissue from the outset rather than as a secondary step.

AI summary
Surgical stapling devices have a surgical buttress attached to an anvil jaw member, a cartridge jaw member, or both. The surgical buttress possesses a therapeutic layer of a therapeutic agent in a pattern thereon. The pattern may reflect various concentrations of a therapeutic agent, different therapeutic agents, or both.
