Problems solved by technology

There is a greater risk of relying solely on the attractive force between the magnetic elements to offset the resistance during the pulling process. For example, the operator may cause the two magnetic elements to separate during the pulling process with too much force, which will eventually lead to cutting failure.

Embodiment

[0102] See Figure 1 - Figure 8This embodiment provides a valve clip 500 removal system including: a capture passage, a cutting channel, a capture fixture 200, a resection device 300. The capture passage is disposed adjacent the valve clip 500, which is disposed adjacent the diapholic valve 400 of the diaphragm clip 500, and the capture fixture 200 is used to capture the fixed valve by capturing the channel and capture the fixed valve. The clip 500 is configured to be placed in the vicinity of the diameter 400 of the mitral valve by the cutting passage after the valve clip 500 is captured, and at least a portion of the valve 400 of the mitral valve is removed. Valvan clip 500.

[0103] like figure 1 As shown, the capture fixture 200 includes a capture fixture 210 that captures the fixing member grip 221. Correspondingly, the capture channel includes a first capture passage and a second capture passage. The first capture channel is used to accommodate the capture fixture grip 221, a...

Abstract

The invention discloses a valve clip removal system. The system includes a capture channel, a resection channel, a capture fixing device (200) and a resection device (300), the capture channel is configured to be disposed proximate to a valve clip, the resection channel is configured proximate to a valve clamped by the valve clip, the capture fixing device (200) is used for capturing the valve clip through the capture channel, and the resection device (300) is used for being placed near the valve through the resection channel after the valve clip is captured and resecting at least part of the valve so as to remove the valve clip. According to the valve clip removal system, the valve clip is removed through system design, the operation process is simple and convenient, and preparation is made for a patient to accept follow-up operations such as transcatheter valve replacement.

Description

Technical field [0001] The present invention relates to the field of medical devices, and in particular, to a valve clip removal system. Background technique [0002] The incidence of cardiac valve is related to age growth, with the advent of aging, the incidence is significantly improved. Among them, mitral regurgitation, MR is a common valve disease. The mitral returns refers to the phenomenon that the blood flows from the left ventricle when the heart is contracted. Severe mitral returns will lead to symptoms such as palpitations, anger, chest tightness, and other symptoms, and severe psychological failure is more than 30% per year. [0003] For patients with mitral valve return current, it is usually used to use surgical open vane repair or valve replacement. With the development of tertiary valve technology, it also uses the tertian valve with the catheter to improve the return. The principle of the mitral valve is to imitate the edge of the firing in surgical repair. The ca...
