Embodiment Construction

[0037] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0038] It should be noted that "distal end" and "proximal end" are used as orientation words, which are commonly used terms in the field of interventional medical devices, where "distal end" means the end away from the operator during the operation, and "proximal end" means The end near the operator during surgery. Axial refers to the direction parallel to the line connecting the center of the distal end and the center of the proximal end of the medical device; radial refers to the distance from the axis in a direction perpendicular to the above-mentioned axial direction, and refers to the distance to the axis along the above-mentioned radial direction.

[0039] like figure 1 As shown, the present invention provides an...

Abstract

The invention discloses a clamping device and a system for fixing tissues. The clamping device comprises at least one clamping unit; the clamping unit includes a clamping mechanism for capturing the tissues; the clamping mechanism comprises a first clamping part and a second clamping part rotationally connected to the first clamping part; the clamping unit further includes a pull rod mechanism detachably connected on the clamping mechanism, one end of the pull rod mechanism is slidably connected on the first clamping part, the other end of the pull rod mechanism is rotationally connected to the second clamping part, and the proximal end, facing to the first clamping part, of the pull rod mechanism drives the second clamping part to rotate relative to the first clamping part to make the clamping mechanism closed during movement, and the pull rod mechanism is divorced from the clamping mechanism after the clamping mechanism is closed. The beneficial effects comprise that the pull rod mechanism is divorced from the clamping mechanism after the clamping mechanism is closed, so the overall weight of the clamping device is reduced and the burden of the valves is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a clamping device and a system for fixing tissues. Background technique [0002] The mitral valve consists of a pair of leaflets, which are located between the left atrium and the left ventricle. The mitral valve opens and closes naturally to control the blood flow in the atrium and ventricle in the appropriate direction. Under normal circumstances, the mitral valve allows blood to flow from the left atrium to the left ventricle in one direction, but if the mitral valve cannot be fully closed during the opening and closing process, the blood flowing through it will flow back in the opposite direction, that is, the mitral valve valve regurgitation. The backflow of blood puts a heavy load on the heart, lungs, and other organs. This extra load can lead to heart failure, irregular heartbeat, stroke, and even sudden death. For mitral regurgitation, an implantable clipping de...
