Abstract

The invention relates to a cutting system for hypertrophic obstructive cardiomyopathy, which comprises a casing cylinder with the tail end blocked, and a window for the hypertrophic interventricular septal myocardium to squeeze in is opened on the side wall of the casing cylinder; the casing cylinder is the same as The shaft is provided with a rotating shaft core, and a supporting block is erected on the wall of the rotating shaft core, and the top of the supporting block is arranged to cover the blade inside the window. of ultrasound probes. The beneficial effect of the present invention is that it can realize the precise resection of interventricular septal myocardial tissue in the operation of hypertrophic obstructive cardiomyopathy, effectively dredging the left ventricular outflow tract, and avoiding side damage to the greatest extent.

Description

technical field [0001] The invention relates to cutting equipment for heart surgery, in particular to a cutting system for hypertrophic obstructive cardiomyopathy. Background technique [0002] Hypertrophic cardiomyopathy (HCM) is a genetic cardiovascular disease that can occur in any age group, and its incidence is about 0.2%. ), characterized by narrow or normal cardiac chambers, according to whether the left ventricular outflow tract is obstructed, HCM is divided into two categories: obstructive (70%) and non-obstructive (30%), hypertrophic obstructive cardiomyopathy ( HOCM) patients have more obvious symptoms and are more prone to fatal complications such as malignant arrhythmia, sudden cardiac death, heart failure or thrombosis. The annual mortality rate of children is as high as 4-6%, and the annual mortality rate of adults is about 2-4%. %. For patients with severe symptoms, poor drug efficacy, and severe left ventricular outflow tract obstruction (resting or excita...
