Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current biosurgical adhesive delivery systems lack efficient and controlled methods for delivering adhesives in minimally invasive surgical settings, particularly in terms of releasing and dispensing adhesives effectively through cannulae and trocars.
Innovation Solution
An adhesive delivery system comprising a cannulated shaft with a bulb portion containing a breakable capsule and a swab portion, where the capsule is designed to break upon stress, allowing adhesive communication through the shaft, and featuring various mechanisms such as duckbill valves, pressurized cartridges, and needle valve assemblies for controlled release and dispensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If adhesive is delivered through cannulae and trocars in minimally invasive surgery, then patient trauma is reduced and recovery is faster, but precise control of adhesive release and dispensing becomes difficult
Solution Approach 1:
The adhesive delivery system employs a self-actuating mechanism where the adhesive cartridge automatically breaks the seal and releases adhesive through pressure differential and mechanical interaction with the swab, eliminating the need for complex external control mechanisms while maintaining precision in minimally invasive settings
Solution Approach 2:
A swab portion acts as an intermediary component between the adhesive cartridge and the application site. The swab absorbs and transports the adhesive from the broken cartridge through the cannula to the target tissue, enabling controlled dispensing without requiring complex mechanical control systems
2Length of moving object
If adhesive delivery systems are designed for minimally invasive procedures, then surgical incisions are smaller, but the complexity of the delivery mechanism increases
Solution Approach 1:
The delivery system is segmented into distinct functional components: a cannulated shaft for insertion, a breakable adhesive cartridge for controlled release, and a swab portion for application. This segmentation allows each component to be optimized independently while maintaining overall simplicity suitable for minimally invasive procedures
Solution Approach 2:
The system utilizes parameter changes in the adhesive cartridge design, specifically transitioning from a sealed state to a broken state, which triggers automatic adhesive release. This parameter change mechanism simplifies the overall delivery system by eliminating complex valve or pump mechanisms

AI summary
An apparatus for applying a liquid substance comprises a bulb portion, a cannulated shaft in fluid communication with the bulb portion, and a swab portion in fluid communication with the cannulated shaft. The bulb portion comprises a capsule. The capsule comprises a liquid substance. The bulb portion further comprises a valve operable to control the flow of a medium through the bulb portion. The bulb portion is operable to rupture the capsule to release the liquid substance. The cannulated shaft is dimensioned to extend percutaneously into a patient. The swab portion is operable to apply the liquid substance. The apparatus may be used to percutaneously apply adhesives to tissue, such as through a trocar or other cannulated member.
