Solution Overview
Problem
Current methods for implanting artificial chordae tendineae to repair heart valve defects are invasive, costly, and involve complex device structures with high surgical risks due to the use of optical fibers and cumbersome monitoring systems.
Innovation Solution
An artificial chordae tendineae implantation system with a clamping device, puncture device, and detection device that uses a probe to verify leaflet clamping without the need for optical fibers, featuring a clamping push rod with distal and proximal clamps and a probe that indicates clamping effectiveness by its ability to enter a chamber, simplifying the device structure and reducing surgical risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical fibers and capturing verification monitors are used to verify leaflet clamping, then measurement precision is improved, but device complexity increases and surgical risks increase
Solution Approach 1:
The patent extracts and eliminates the complex optical fiber verification system and external monitoring equipment from the surgical device. Instead, it uses a simple probe that directly interacts with the leaflet tissue mechanically, removing the need for optical components and external monitors, thus simplifying the device structure while maintaining verification capability
Solution Approach 2:
The probe performs self-verification by mechanically interacting with the clamped leaflet. The probe's ability to penetrate or be blocked by the leaflet provides automatic feedback on clamping effectiveness without requiring external monitoring systems or complex optical verification apparatus
2Measurement precision
If optical fibers are introduced into the patient's body with the device, then measurement precision is improved, but reliability decreases due to increased surgical risks
Solution Approach 1:
The patent replaces the optical fiber-based verification system with a purely mechanical probe system. The probe mechanically interacts with the leaflet through direct contact and penetration attempts, eliminating the need to introduce optical fibers into the patient's body, thereby reducing surgical risks while maintaining verification accuracy
Solution Approach 2:
The probe is designed as a simple, disposable mechanical component that can be easily manufactured and discarded after single use. This eliminates the need for expensive, complex optical fibers and monitoring equipment, reducing both surgical risks and costs while providing sufficient verification functionality
3Measurement precision
If capturing verification monitors are equipped, then measurement precision is improved, but manufacturing cost and operation cost increase
Solution Approach 1:
The patent removes the expensive capturing verification monitors and optical fiber components from the system. The verification function is achieved through a simple mechanical probe that can be manufactured at low cost using basic materials and processes, eliminating the need for expensive optical components and monitoring equipment
Solution Approach 2:
The probe is designed as a disposable component made from inexpensive materials that can be easily manufactured and discarded after single use. This eliminates the need for expensive, complex verification monitors and optical fibers, significantly reducing both manufacturing costs and operational costs while maintaining adequate verification functionality

AI summary
An artificial chordae tendineae implantation system comprises a clamping device (300), a puncture device (400), a pushing device (200), and a detection device (600). The pushing device (200) comprises a pushing duct (210). The clamping device (300) comprises a clamping push rod (330) accommodating an artificial chordae tendineae (100), and a far end clamping head (310) used for cooperating to clamp a valve leaflet (900). A near end clamping head (320) is disposed at the far end of the pushing duct (210). The detection device (600) comprises at least one probe (610), and the probe (610) is movably disposed in the pushing duct (210) in a penetrating manner. A probe outlet (321) is formed in a clamping surface of the corresponding near end clamping head (320) or the corresponding far end clamping head (310). A probe accommodation chamber (316) opposite to the probe outlet (321) is disposed on the clamping surface of the corresponding far end clamping head (310) or the corresponding near end clamping head (320) or. When the far end clamping head (310) and the near end clamping head (320) are closed, the far end of the probe (610) extends out of the probe outlet (321) and is accommodated in the probe accommodation chamber (316). By means of the detection device (600), whether the valve leaflet (900) is sandwiched between the far end clamping head (310) and the near end clamping head (320) can be quickly and accurately detected, and the structure is simple, and the operations are simple and convenient.
