Tricuspid Valve Blocking Tube With Coronary Sinus Position Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tricuspid regurgitation surgical instruments face challenges in accurately blocking the tricuspid valve orifice due to varying distances between the inferior vena cava and tricuspid valve, leading to potential right ventricular volume overload and right-sided heart failure, especially in patients with a long IVC-TV distance, and issues with the blocking part tilting during insertion.
Innovation Solution
A tricuspid regurgitation surgical instrument featuring a position-fixing tube with a blocking part and a position-fixing tube, where the position-fixing tube is inserted into the coronary sinus to maintain a consistent penetration angle and prevent rotation or movement, ensuring the blocking part aligns with the tricuspid valve plane, using guide wires for precise insertion and stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the insertion tube is inserted into the inferior vena cava to reach the tricuspid valve, then the blocking part can be positioned to block the orifice, but the varying distance between the inferior vena cava and tricuspid valve causes inaccurate blocking and potential tilting of the blocking part
Solution Approach 1:
The patent introduces a position-fixing tube as an intermediary component that is inserted into the coronary sinus to serve as a stable reference point. This mediator establishes a fixed geometric relationship with the tricuspid valve, allowing the blocking part to be accurately positioned regardless of variations in the distance between the inferior vena cava and tricuspid valve. The position-fixing tube acts as a mediator that translates the variability of patient anatomy into a consistent positioning reference.
Solution Approach 2:
The patent changes the reference parameter for positioning from the inferior vena cava (which has variable distance to the tricuspid valve) to the coronary sinus (which has a more consistent anatomical relationship with the tricuspid valve). By changing the reference point and establishing a fixed penetration angle relative to the position-fixing tube, the system achieves accurate blocking across different patient anatomies.
2Reliability
If the blocking part is inserted through the insertion tube to block the tricuspid valve orifice, then the orifice can be blocked, but the blocking part may tilt toward one side and fail to form a plane similar to the leaflet plane
Solution Approach 1:
The patent establishes a fixed penetration angle parameter by designing the blocking part at a specific angle relative to the position-fixing tube. This angular parameter ensures that when the position-fixing tube is correctly positioned in the coronary sinus, the blocking part automatically forms a plane similar to the leaflet plane of the tricuspid valve, preventing tilting and ensuring reliable blocking without requiring complex manual positioning adjustments.
3Reliability
If a permanent method is used to treat tricuspid regurgitation, then the orifice can be permanently blocked, but right ventricular volume overload occurs due to sudden increase in blood flow causing right-sided heart failure
Solution Approach 1:
The patent employs a temporary blocking solution that can be dynamically adjusted and removed. The device allows for gradual adaptation of blood flow by being temporarily insertable and removable, enabling clinicians to monitor patient response and adjust treatment duration. This dynamic approach prevents sudden, permanent blood flow changes that cause right ventricular volume overload and right-sided heart failure, while still providing effective treatment during the adaptation period.
4Ease of operation
If the insertion tube is rotated or moved after placement, then the blocking part position changes, but this causes inaccurate blocking of the orifice
Solution Approach 1:
The patent performs preliminary positioning by inserting the position-fixing tube into the coronary sinus first to establish a stable reference framework before inserting the blocking part. This preliminary action creates a fixed geometric relationship that prevents subsequent rotation or movement of the blocking part, ensuring accurate and stable blocking of the tricuspid valve orifice throughout the procedure.

AI summary
The present disclosure relates to a tricuspid regurgitation surgical instrument having a position-fixing tube that is for temporarily treating tricuspid regurgitation, and more particularly, to a tricuspid regurgitation surgical instrument having a position-fixing tube that is a surgical instrument temporarily inserted into an orifice of the tricuspid valve to check whether right-sided heart failure has occurred, which may occur when tricuspid regurgitation is treated using a permanent method in a patient with tricuspid regurgitation, and that has a position-fixing tube inserted into a coronary sinus so that a blocking part configured to block the orifice of the tricuspid valve penetrates a plane similar to a plane of leaflets of the tricuspid valve and has a penetration angle which allows the blocking part to efficiently block the orifice of the tricuspid valve.
