Embodiment Construction

[0060] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.

[0061] refer to Figure 1 to Figure 20 , a clip for heart valve repair, comprising a capture device 100 , at least two capture control pieces, a connecting base 200 and at least two auxiliary clamping pieces 300 .

[0062] refer to Figure 1 to Figure 6 , the capture device 100 is used to capture a heart valve, and the capture device 100 includes at least two capture parts 110 and a fitting part 120 .

[0063] The number of capture elements 110 can be determined according to the number of leaflets of the heart valve to be captured, such as two capture elements 110 or three capture elements 110 . The inner side of the catcher 110 is provided with catcher barbs 111 . refer to Figure 7 and Figure 8 The barbs 111 of the catcher can be a shuttle-like...

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a heart valve repairing clamp. The invention discloses a heart valve repair clamp which comprises a capturing device. The capturing device comprises at least two capturing pieces, the inner sides of which are provided with capturing piece barbs for capturing valve leaflets; the attaching piece is provided with at least two attaching faces, the attaching faces and the capturing piece are oppositely arranged, the near ends of the attaching faces are fixedly connected with the connecting positions of the near ends of the capturing piece, and the attaching faces can rotate relative to the connecting positions so as to adjust opening and closing of the capturing device. According to the valve leaflet capturing device, the multiple capturing pieces share one attaching piece, the number of components is reduced, the included angle between each capturing piece and the attaching piece is increased during use, and valve leaflet capturing is more convenient. The attaching piece is fixedly connected with the near end of the capturing piece, axial relative movement is avoided, and dislocation and axial relative friction of the combining faces of the attaching piece and the capturing piece are avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a heart valve repair jig. Background technique [0002] Cardiac valvular insufficiency, especially mitral / tricuspid atrioventricular regurgitation or regurgitation, has received increasing attention due to its high incidence. According to statistics, there will be approximately 7.5 million patients in my country who need intervention for mitral regurgitation in 2020. However, due to the immaturity of the market or the high price of surgery, there are currently only 40,000 surgical operations per year, and the treatment rate is extremely low. [0003] Most of the research is on edge-to-edge repair. At present, there is an existing mitral valve repair jig, which enters the left atrium from the femoral vein through the right atrium, punctures the interatrial septum, and repairs the mitral valve across the valve. Many parts are involved, the preparation process i...
