Abstract

The invention provides an anchoring instrument, which mainly comprises a core shaft, an anchoring structure connected to the core shaft, a sleeve shaft connected to the core shaft in a sleeving mode and a clamping structure connected to the sleeve shaft, wherein the anchoring structure can be used for anchoring target tissue; the core shaft can axially move relative to the sleeve shaft so as to drive the anchoring structure to move from a non-clamping position to a clamping position; furthermore, the clamping structure can be switched from the release state to the clamping state so as to clamp the target tissue anchored on the anchoring structure, so that the anchoring force of the anchoring instrument can be improved; and the stability of the anchoring state can be improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of medical devices, and in particular to an anchoring device. Background technique [0002] The common diseases of human heart valves are valvular insufficiency and leaflet prolapse. Taking the mitral valve as an example, during systole, a part of blood from the left ventricle flows back to the left atrium through the incompetent mitral valve orifice. The left atrium receives blood from the left ventricular regurgitation and blood from the pulmonary vein at the same time, and the blood volume and pressure of the left atrium increase significantly, resulting in left atrial hypertrophy. During the diastolic period, more blood flows from the left atrium to the left ventricle, causing the left ventricle to hypertrophy due to the strengthening of contraction. After the compensation period progresses to the decompensation period, heart failure occurs in both the left atrium and left ve...
