Mitral valve repair device capable of being captured and fixed

Abstract

The invention relates to a mitral valve repair device capable of being captured and fixed, and belongs to the technical field of medical instruments. The device comprises an atrial septum anchoring device I, a coronary sinus great vein or heart wall anchoring device II and a draft line. The draft line is arranged between the atrial septum anchoring device I and the coronary sinus great vein or heart wall anchoring device II. The atrial septum anchoring device I is provided with a drafting line self-locking block, and the drafting line self-locking block is provided with a lock key structure connected with the screw conveying device. And a self-positioning or self-centering convex-concave structure is adopted as the lock key structure, so that a screw conveying device can be conveniently aligned with and screwed into the drafting line self-locking block. After the screw conveying device is released in an operation, if the position needs to be corrected again and the length of a suture line needs to be adjusted, the screw conveying device grabs the drafting line self-locking block again, and the drafting line self-locking block is connected with the screw conveying device. And the technical problem that the screw conveying device is aligned with and screwed into the drafting line self-locking block is solved.

Description

technical field [0001] The invention relates to a mitral valve repair device capable of capturing and fixing, and belongs to the technical field of medical instruments. Background technique [0002] Mitral regurgitation (MR) is the most common valvular disease. European and American epidemiological research data show that among people over 75 years old, the attack rate of MR is as high as 10%, which is significantly higher than that of aortic valve disease. Similarly, with the aggravation of the aging process of our country's population, mitral valve regurgitation disease will also lead to a heavy medical burden. Mitral valve repair or replacement is the gold standard for MR treatment, but some studies have shown that as many as half of patients with severe MR do not choose surgical treatment, and the reason is largely related to its surgical risk. This majority of patients who are poorly tolerant to surgery urgently need a less invasive treatment as an alternative, so inte...

Mitral valve repair or replacement is the gold standard of care for MR, but some studies have shown that as many as half of patients with severe MR do not opt ​​for surgery, largely because of the risks associated with surgery

Aligning and screwing in the screw delivery device and the self-locking block of the drafting wire has become a difficult problem, because it is difficult for doctors to rely on experience or imaging methods such as contrast-enhanced ultrasound when the body cannot be directly viewed.
