Device for interventional therapy of adult congenital heart disease under guidance of echocardiogram

Abstract

The invention discloses a device for interventional therapy of adult congenital heart disease under the guidance of echocardiogram. The device comprises a path finding guide wire and a right heart scale catheter, and the path finding guide wire comprises a guide wire AB section, a guide wire BC section, a guide wire CD section, a guide wire DE section, a guide wire EF section, a guide wire FG section and a guide wire GH section. By arranging the path finding guide wire and guide wire scales, the probability of entering small vessels along the path can be remarkably reduced by adopting a U-shaped guide wire head. When the path finding guide wire is withdrawn to the middle of the right heart scale catheter, the right heart scale catheter can change the advancing direction of the path findingguide wire through rotation, and therefore it is guaranteed that the path finding guide wire safely passes through inferior vena cava, superior vena cava, atrial septum, atrioventricular valve, pulmonary artery and other parts and reaches a preset position under echocardiogram monitoring. Conditions are created for follow-up of the matched right heart scale catheter to a target site and measurement of the length of the matched right heart scale catheter entering the body, and it is in a safe path that the matched right heart scale catheter is pushed out of a purple area of the routing guide wire along the routing guide wire.

Description

technical field [0001] The invention relates to the technical field of heart disease treatment devices, in particular to a device for interventional treatment of adult congenital heart disease guided by echocardiography. Background technique [0002] Traditional percutaneous interventional techniques are generally completed in the catheterization room under the guidance of radiation, and most patients need to use contrast media, which will bring potential radiation damage to patients and operators, and the use of contrast media has the risk of renal function damage and allergy; Moreover, the operator needs to wear heavy protective equipment, which not only brings inconvenience to the operation, but also increases the labor intensity of the operator. [0003] In 2000, Ewert et al. reported for the first time that ASD closure was performed under the guidance of transesophageal echocardiography (TEE) without X-ray fluoroscopy. Chinese Expert Consensus. Due to the separation f...
