Abstract

The technical solution of the present invention discloses an adjustment device for coarctation of the aortic arch and an operation method thereof, including a base plate, a clip applier, and a dial gauge fixed on the base board, and the thimble of the dial gauge can movably touch the head end of the fixed arm; The adjusting part is fixed on the base plate and close to the handle end of the movable arm. The adjusting part has an adjusting bolt, and the adjusting bolt can movably touch the handle end of the movable arm. Far away; the technical solution of the present invention can accurately adjust the degree of aortic arch constriction through the adjustment device for aortic arch constriction, and at the same time, because the dial gauge can realize continuous adjustment of different constriction diameters, the constriction diameter is no longer affected by the prior art. Restrictions on needle specifications; the technical solution of the present invention can reduce the errors caused by the operator's personal habits and sensory sensitivity when using needles for mediation, and the adjustment accuracy of the aortic arch coarctation adjustment device of the present invention is high.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an adjusting device for coarctation of the aortic arch and an operating method thereof. Background technique [0002] Coarctation of the aortic arch is an important method used in the study of cardiac disease. This method is used to simulate the damage of hypertensive heart disease, and establish the pathological conditions of increased cardiac afterload in experimental animals (mice), so as to simulate and study the processes of cardiac hypertrophy and heart failure. In this method, the aortic arch is constricted or narrowed by mechanical methods (ligation or application of titanium clips), resulting in increased pressure proximal to the stenosis. At this time, the afterload of the heart increases, and further myocardial hypertrophy and heart failure occur. [0003] In this technique, the degree of artificially imposed mechanical stenosis will have an important impac...
