Problems solved by technology

Second, transepicardial approach requires “dry” pericardiocentesis, which is only suitable for interventional procedures for a small number of arrhythmias originating in the epicardium, while most arrhythmias originate in the endocardium
In addition, the epicardial space is small, it is difficult to place multiple catheters for electrophysiological examination and mapping, and the end point of the operation is not clear

Abstract

The invention provides a puncture device for puncturing an atrial septal defect patch. The puncture device comprises a body of a rod-shaped structure and a puncture component fixedly arranged at the far end of the body. The puncture component is of a sheet-shaped structure with a blade-shaped edge and an arc-shaped cross section, the sheet-shaped structure can be folded to form a cylindrical structure, and the axis of the cylindrical structure is parallel to the axis of the body. According to the puncture device for puncturing the atrial septal defect patch, atrial septal puncture of the atrial septal defect patch can be completed, and a minimally invasive interventional therapy pathway from the outside to the left atrium is established under the condition that a patient after an atrial septal defect surgery is not subjected to thoracotomy; a wound formed by the operation is small, damage to a patient is small, and the patient can recover easily.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a puncture device for puncturing a patch of atrial septal defect. Background technique [0002] Atrial septal puncture is the only way to enter the left heart system through the right heart outside the body during cardiac intervention. For example, mitral valve dilatation and radiofrequency ablation of atrial fibrillation require atrial septal puncture first. Puncture of the interatrial septum is the first step to a successful operation. At present, the most common atrial septal puncture requires the use of an atrial septal puncture needle and supporting guide wire and sheath. [0003] Atrial septal defect (hereinafter referred to as atrial defect) is a common heart surgery disease. Artificial materials commonly used as patches in surgical repair of atrial defects include polyester, nylon, polyester fibers, and the like. Among them, polyester patch is a common artifici...
