Abstract

The technical scheme of the invention discloses an adjustment device of an aortic arch coarctation operation and an operation method thereof. The adjustment device comprises a base plate, a clamp applying device and a dial indicator fixed on the base plate, wherein a thimble of the dial indicator can be movably in contact with the head end of a fixed arm; an adjusting member close to the handle end of a movable arm is fixed to the base plate, the adjusting member is provided with an adjusting bolt movably abutting against the handle end of the movable arm, and the movable arm and the fixed armare close to or far away from each other through pre-tightening or loosening of an adjusting screw. According to the technical scheme, the degree of the aortic arch coarctation can be accurately adjusted through the adjustment device of the aortic arch coarctation operation, meanwhile, because the dial indicator can realize continuous adjustment of different coarctation diameters, so that the coarctation diameter is no longer limited by the needle specifications in the prior art; according to the technical scheme, errors caused by different personal habits and sensory sensitivity when an operator uses a needle for adjustment can be reduced, and the adjustment precision of the adjustment device of the aortic arch coarctation operation 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...
