Mitral valve repair device with protection structure

Abstract

The invention relates to a mitral valve repair device with a protection structure, 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. And a structure for protecting cardiovascular tissues is arranged between at least one of the anchoring device I and the anchoring device II and the draft line. The technical problem that the atrial wall is damaged due to the fact that the atrial wall is rubbed by the contact position of a fixing pipe and the drafting line is solved. The friction damage of the mitral valve repair device to the atrial wall can be effectively relieved. The injury caused by the puncture of the atrial wall can be closed. Healing of a puncture opening can be promoted. And the fixing tube can be fixed to ensure that the instrument does not shift, so that the instrument stably plays a role.

Description

technical field

[0001] The invention relates to a mitral valve repair device with a protective structure, 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 interv...

Embodiment Construction

[0034] In order to make the present invention more obvious and understandable, the preferred embodiments are described in detail as follows in conjunction with the accompanying drawings:

[0035] Such as Figure 1-11 As shown, the present invention provides a mitral valve repair device with a protective structure, including atrial septal anchoring device one 15, coronary sinus great vein or heart wall anchoring device two 16 and stretching wire 4; atrial septal anchor A stretching line 4 is provided between anchoring device one 15 and coronary sinus great vein or heart wall anchoring device two 16; at least one of anchoring device one 15 and anchoring device two 16 and stretching line 4 are provided There are protective structures. At least one of the first anchoring device 15 and the second anchoring device 16 includes a fixed tube 3; the number of drafting wires 4 is set to be greater than or equal to one. The fixed tube 3 includes an elastic anchoring structure 6 that fit...
