Artificial chordae implantation system provided with detection device

Abstract

The invention discloses an artificial chordae implantation system provided with a detection device. The artificial chordae implantation system comprises a clamping device, a puncture device, a push device and a detection device, wherein the push device comprises a push catheter; the clamping device comprises a clamping push rod in which an artificial chordae is accommodated as well as a distal clamping head and a proximal clamping head which are cooperated for clamping a valve leaflet; the detection device comprises at least one probe; the probe is movably inserted into the push catheter; a detection outlet is kept in the clamping surface of the proximal clamping head or the distal clamping head, and correspondingly, a probe accommodating cavity, which is opposite to the probe outlet, is kept in the clamping surface of the distal clamping head or the proximal clamping head; and the distal end of the probe is accommodated in the probe accommodating cavity from the probe outlet when thedistal clamping head and the proximal clamping head are closed. According to the artificial chordae implantation system provided by the invention, it can rapidly and accurately detect whether the valve leaflet is clamped between the distal clamping head and the proximal clamping head or not via the detection device of a mechanical structure; the system is simple in structure, simple and convenientto operate and low in surgical risk; and the system can reduce production cost of apparatuses and reduce economic burdens of patients.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a device for repairing heart valve defects, in particular to an artificial chord implantation system with a detection device. Background technique [0002] The mitral valve is a one-way "valve" between the left atrium (abbreviation: LA) and the left ventricle (abbreviation: LV), which can ensure blood flow from the left atrium to the left ventricle. See figure 1 , a normal healthy mitral valve has multiple chordae. The leaflets of the mitral valve are divided into anterior leaflet and posterior leaflet. When the left ventricle is in a diastolic state, the two are in an open state, and blood flows from the left atrium to the left ventricle; when the left ventricle is in a systolic state, the chordae are stretched to ensure The valve leaflets will not be rushed to the atrium side by the blood flow, and the front and rear leaflets are well closed, thereby ensuring that blood...

AI Technical Summary

Problems solved by technology

The artificial chord implantation device uses optical fibers in interventional therapy devices, resulting in a complex structure of the device, and the optical fiber needs to enter the patient's body with the device body, which increases the risk of surgery

In addition, since the capture verification system needs to be equipped with a capture verification monitor, the device structure is complicated, the production process is complicated, and the production cost and operation cost are high.
