Abstract

The invention relates to a direct puncture adjustable mitral valve repair device, 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, A drawing line is arranged between the atrial septum anchoring device I and the coronary sinus great vein or heart wall anchoring device II; The first atrial septum anchoring device is provided with a structure used for adjusting the position of a drafting line. The defects in the prior art are overcome, and the best shortened heart anterior-posterior diameter is obtained by adjusting the position and angle of the draft line in the instrument implanting process, so that mitral valve regurgitation is improved. A one-way locking anchor is attached to the drawing line for tensioning the atrium, so that the drawing line is prevented from loosening and falling off, and the effect of locking after the diameters of the front and rear walls of the atrium are stretched and shortened is achieved; A barb type anchor or a spring type anchor is adopted at the fixed end of the coronary sinus great vein or heart wall anchoring device, the atrial wall or blood vessels are prevented from being damaged, the contact region with the tissue is increased, stability is enhanced, and tissue endothelialization is promoted.

Description

technical field [0001] The invention relates to a direct puncture adjustable mitral valve repair device, which 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 interve...
