Selective Tissue Removal via Fluid Jet Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current minimally invasive surgical techniques often cause damage to non-targeted tissues and require multiple entry points and foreign visualization compounds, leading to prolonged recovery times and increased costs, necessitating a method for selective and safe removal of pathologic tissues with minimal trauma.
Innovation Solution
A surgical instrument with a dual lumen system that uses a high-pressure jet of fluid to create a cutting and suction force, allowing for the selective removal of specific tissue types while minimizing the number of entry points and foreign compounds introduced into the body, by adjusting the fluid pressure to target and remove pathologic tissues like type III collagen without disturbing healthy type I collagen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional minimally invasive techniques are used, then surgical procedures can be performed with reduced trauma, but multiple entry points and foreign visualization compounds are required which prolong recovery time and increase costs
Solution Approach 1:
The patent combines multiple functions (cutting, suction, and visualization) into a single surgical instrument. The instrument includes a nozzle for delivering pressurized fluid jets to cut tissue, an aperture for receiving the fluid jet and creating suction force to remove cut tissue, and integrated imaging capability to visualize the surgical site, thereby eliminating the need for multiple separate instruments and entry points
Solution Approach 2:
The surgical instrument is designed as a multi-functional device that can perform cutting, tissue removal, and imaging operations simultaneously through a single entry point. The device universally handles multiple surgical tasks that traditionally required separate instruments, reducing procedural complexity and recovery time
2Productivity
If conventional surgical techniques are used, then tissue removal can be achieved, but non-targeted tissues are damaged and multiple instruments are required
Solution Approach 1:
The patent employs a high-pressure fluid jet delivered through a precisely positioned nozzle that concentrates cutting energy locally at the target tissue site. The suction aperture is positioned to selectively aspirate cut tissue while the imaging system provides real-time visualization to guide the nozzle, ensuring that only the targeted pathologic tissue is removed while healthy surrounding tissues remain undisturbed
3Adaptability or versatility
If multiple instruments and entry points are used, then comprehensive tissue treatment is possible, but device complexity and procedural cost increase
Solution Approach 1:
The patent integrates cutting, suction, and imaging functions into a single instrument, reducing the number of separate devices and entry points required. The instrument includes a nozzle for fluid jet delivery, an aperture for suction, and imaging capability, all combined in one device that can be inserted through a single entry point
Solution Approach 2:
The surgical instrument is designed as a universal multi-functional device that performs cutting, tissue removal, and imaging operations simultaneously. This single device replaces multiple specialized instruments, simplifying the procedural setup while maintaining comprehensive treatment capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The instrument effectively removes pathologic tissues with minimal disruption to healthy tissues, reducing recovery time and costs by using a single device to create a cutting and suction force that selectively targets and evacuates specific tissue types, as demonstrated by its ability to reduce tendinopathic tissue volume fractions in tendons.
Implementation Method 1
uses a high-pressure jet of fluid to create a cutting and suction force
Implementation Method 2
create a jet of fluid and suction forces at the aperture of the second lumen
