Embodiment Construction

[0064] The following description is a preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications are also considered Be the protection scope of the present invention.

[0065] Orientation definition: In the field of medical device technology, the orientation close to the operator is usually defined as the proximal end, and the orientation away from the operator is defined as the distal end. The radial direction refers to the direction along the diameter or radius, and the axial direction refers to the direction along the central axis. Direction, the radial direction and the axial direction are perpendicular to each other, and the circumferential direction refers to the circumferential direction around the central axis. Unless otherwise defined, all technical and scientific t...

Abstract

The invention provides an integrated anchor which comprises a locking rod, a locking sleeve arranged outside the locking rod in a sleeving mode and an anchoring piece. The anchoring piece is connected with the far end of the locking rod or the far end of the locking sleeve; a radial gap is formed between the locking rod and the locking sleeve; the locking rod is provided with a threading hole for threading artificial chordae tendineae; at least one end of the threading hole is communicated with the radial gap between the locking rod and the locking sleeve; the locking rod and the locking sleeve move relatively, so that the artificial chordae tendineae is locked in the radial gap between the locking rod and the locking sleeve; and the anchoring piece is used for being anchored into cardiac muscle tissues. The integrated anchor provided by the invention integrates the functions of anchoring and locking the artificial chordae tendineae, and when the integrated anchor is applied to a chordae tendineae repair operation, the surgical operation can be simplified, the number of instruments is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an integrated anchor. Background technique [0002] In the repair surgery for mitral regurgitation (MR), traditional surgical operations are traumatic and risky, and there is a great demand for minimally invasive repair of mitral regurgitation in clinical practice. Interventional minimally invasive treatment of mitral valve regurgitation has the advantages of less trauma and fewer complications. The implantation of artificial chordae is a kind of interventional mitral valve repair. Its operating principle is: the suture is sent into the left ventricle through the catheter, so that one end of the suture is fixed to the mitral valve leaflet, and the other end of the suture is One end is connected to the left ventricular myocardial wall or papillary muscle through an anchor to form an artificial chord. However, there are still the following technical problems: the anchors ...
