Endoscopic Fluid Delivery Adapter for Tissue Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscopic surgery faces challenges in tissue movement monitoring and visualization, particularly in restricted visual conditions, where existing methods for marking tissues are invasive or difficult to administer, and there is a need for a non-invasive fluid-delivery system that can adapt to pre-existing tools to deliver fluids, gases, or solids under positive pressure conditions.
Innovation Solution
A fluid-delivery system comprising an adapter that connects with a grasping instrument and a fluid-delivery device, featuring a tip, tip saturator, flow regulators, and a fluid housing, designed to apply fluids to tissues while functioning under positive pressure conditions, allowing for marking, therapeutic agent delivery, and use in various applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fluorescent dies or contrasting agents are injected intravenously or with medical imaging to highlight tissue areas, then tissue visualization is improved, but the procedure becomes more invasive and difficult to administer to specific target locations
Solution Approach 1:
The patent extracts the contrasting agent delivery from the intravenous route and places it directly at the surgical site through the endoscopic instrument. The reservoir containing the contrasting agent is positioned within the instrument, allowing direct application to the target tissue without systemic injection or complex imaging equipment.
Solution Approach 2:
The patent introduces a contrasting agent as an intermediary substance that enhances tissue visibility. This agent is delivered through the endoscopic instrument's reservoir and applied directly to the tissue, serving as a mediator between the surgeon and the target tissue to improve visualization without requiring invasive imaging procedures.
2Reliability
If a fluid-delivery device is designed to deliver fluid under positive pressure conditions in endoscopic surgery, then the device can function effectively in surgical environments, but the device complexity increases
Solution Approach 1:
The patent merges the fluid-delivery mechanism with the existing endoscopic instrument structure. The reservoir, flow regulator, and delivery tip are integrated into the instrument's framework, allowing the device to function under positive pressure conditions while maintaining compatibility with standard endoscopic systems and minimizing overall complexity.
Solution Approach 2:
The patent designs the instrument to serve multiple functions: it can perform both the original surgical function of the endoscopic instrument and the additional function of delivering contrasting agents or therapeutic fluids. This multi-functionality is achieved through an adaptable reservoir system that can be attached to various endoscopic instruments, reducing the need for separate specialized devices.
3Adaptability or versatility
If an adapter is designed to connect with pre-existing tools to enable fluid delivery, then adaptability is improved, but the device complexity increases
Solution Approach 1:
The adapter is designed with universal connection features that allow it to attach to multiple types of pre-existing endoscopic instruments. Standardized connection interfaces and modular components enable the same adapter design to work with different instrument types, achieving broad adaptability without requiring complex customizations for each tool.
Solution Approach 2:
The adapter is segmented into distinct functional components: a connection interface for attaching to the instrument, a reservoir for holding the contrasting agent, and a delivery mechanism with flow regulators. This segmentation allows each component to be optimized independently and facilitates easy assembly, disassembly, and adaptation to different instrument types, reducing overall complexity while maintaining versatility.

AI summary
A fluid-delivery system, a fluid-delivery device, and an adapter are described herein for applying fluid to tissue. The adapter generally includes a proximal portion and a distal portion. The proximal portion includes a grasping handle to be grasped by a grasping instrument having a pair of jaws, and a collar surrounding the grasping handle to increase a grip on the pair of jaws. The distal portion is adapted to connect with the fluid-delivery device. The fluid-delivery device generally includes a tip to apply the fluid to the tissue, a tip saturator to supply the tip with the fluid, a flow regulator to control fluid flow to the tip saturator, and a fluid housing to contain the fluid which is appliable to the tissue. The fluid-delivery system includes the adapter connected with the fluid-delivery device. The fluid-delivery system is particularly advantageous for marking tissues during endoscopic surgical procedures.
