Description

Multi-head valve chordae tendineae reconstruction line

Technical Field

The utility model relates to the technical field of medical machinery, particularly, relate to a line is rebuild to multiheaded valve chordae tendineae.

Background

The prolapse of the valve caused by rupture, elongation or other pathological changes of the chordae tendineae of the mitral valve or the tricuspid valve is common in clinic, can cause pathological changes such as valve regurgitation and the like, and can lead to heart failure, loss of life capacity and even death of patients in severe cases.

For severe mitral regurgitation patients requiring surgical treatment, a common surgical approach is valve replacement or valve repair.

The valve replacement is simple and has definite operation effect, and good short-term effect can be obtained, but after the operation, anticoagulant drugs need to be taken for a long time, and complications of excessive anticoagulation hemorrhage or insufficient anticoagulation embolism sometimes occur. And the long-term survival rate and complication rate are inferior to those of valve repair surgery.

Valve repair surgery is technically difficult and is converted into valve replacement surgery if repair fails. However, patients who successfully repair the valve do not need long-term anticoagulation, the post-operation life quality is high, the self-feeling of the patients is good, and the long-term survival and complication conditions are better than those of patients who change the valve, so the valve repair operation becomes the first choice for doctors with technical conditions and patients with good conditions.

For patients with broken chordae tendineae, it is often necessary to replace the native chordae with artificial chordae tendineae during the valve repair procedure. In the past, cord reconstruction has been performed using gore tax lines. When the reconstruction range is large, a plurality of sutures need to be implanted, and the space of the papillary muscle is limited, so that the operation difficulty is increased. And the method fixes the stress point of the valve leaf at the suture, and the long-term concentrated stress can cause the tear at the suture and the failure of the forming operation. For some patients with simultaneous rupture of the primary, secondary and tertiary chordae, only the primary chordae are typically rebuilt, which further increases the tension of the primary chordae at the valve edge sutures and makes it easier to tear. Traditional chordal transfer procedures transfer the secondary chordae to the valve edge, which also reduces the stress points on the valve to the extent that the transferred chordae are under greater tension, potentially resulting in a long-term failure of the procedure.

Normally a chordae tendineae emanating from the papillary muscles will become 2-3 branches in the vicinity of the valve, on the one hand pulling a larger area of the valve edge and at the same time reducing the strength of the force at the link with the valve edge. Simultaneously, the primary, secondary and tertiary chordae tendineae can better maintain the shape and function of the valve when bearing force on the valve, and the stress intensity of a single chordae tendineae is reduced. The normality of the valve and the subvalvular structure is also a good guarantee of the cardiac function, and the possibility of postoperative complications can be reduced.

SUMMERY OF THE UTILITY MODEL

The present invention aims at least solving one of the technical problems existing in the prior art or the related art.

In view of the above, the present invention is directed to a reconstruction line for chordae tendinae of a multiheaded valve.

In order to achieve the above object, the present invention provides a multi-headed valve chordae tendineae reconstruction line, including: the suture fixing part is provided with a first end and a second end which are oppositely arranged, the first end is connected with at least one valve suture, the valve suture is used for being connected with valve leaflets, and the second end can be oppositely fixed with papillary muscles.

In the above technical solution, preferably, the second end is connected with at least one papillary muscle suture, and the papillary muscle suture is used for connecting with the papillary muscle.

In this scheme, the suture fixed part is connected valve suture and papillary muscle suture, and like this, the suture fixed part can adjust quantity proportion between them as the anchor point of valve suture and papillary muscle suture to can stitch fixed position as valve suture, can rationally set up the quantity of valve suture and papillary muscle suture according to actual conditions, can reduce the operation degree of difficulty, can be applicable to the patient of different grade type simultaneously.

Simultaneously, through setting up the suture fixed part, can also effectively solve the great problem of the operation degree of difficulty that leads to on the suture that a large amount of is fixed in narrow and small and limited space's papillary muscle, and then reduce the operation degree of difficulty.

It is also pointed out that by arranging the suture fixing part, the suture fixing part can also prevent the single valve suture from being too high in tension or the single papillary muscle suture from being too high in tension, so that the effect of uniform stress is achieved, the valve suture or the papillary muscle suture is prevented from being lost due to falling, and the service life is prolonged.

Finally, when the valve suture is multiple, if one valve suture falls off from the valve, the overall effect of the multi-head valve chordae tendineae reconstruction line cannot be influenced. Therefore, the multi-head valve chordae tendineae reconstruction line has higher reliability.

In any of the above solutions, preferably, the valve sutures are sutured on the suture fixing part; and/or papillary muscle sutures are sutured on the suture fixation portion.

In any of the above solutions, preferably, the valve suture is passed through the valve leaflet, and both ends of the valve suture are fixed at the first end.
