Problems solved by technology

The traditional pericardiocentesis requires puncture while imaging, commonly known as conventional pericardiocentesis, because this puncture method uses a contrast agent, in order to distinguish it from this puncture method, it is called wet wet pericardiocen

Embodiment Construction

[0018] The technical solutions of the present invention will be described in further detail below through the embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0019] The pericardiocentesis of the present invention includes 3 steps. Step 1 is the preparatory work before the operation, prepare surgical instruments, such as puncture guide wire, pericardial puncture needle, Y-valve and syringe, etc. First, before insertion, pass the puncture guide wire through the puncture needle to confirm whether the guide wire can pass smoothly and without hindrance and whether the shape of the puncture guide wire is normal. Secondly, inject heparinized saline into the puncture needle through the Y-shaped valve, and rinse the puncture needle tube thoroughly. In the third step, the puncture guide wire is retracted into the puncture needle tube.

[0020] Step 2 is the selection of puncture position. By analyz...

Abstract

The invention discloses a dry puncturing method of dry pericardium. The dry puncturing method comprises 3 steps of step 1, performing preparation before operation; step 2, selecting puncturing body positions, wherein the puncturing body positions are the left front positions; and step 3, performing a pericardium puncturing process. According to the dry puncturing method of dry pericardium disclosed by the invention, through analyzing characteristics of heart, musculus diaphragm, xiphoid process, a breastbone anatomic structure and X ray imaging, appropriate puncturing positions and appropriateneedle injection angles are selected, and under the guidance of an appropriate X ray image, under the premise that a contrast agent is not used, the pericardium puncturing process is finished, and apassage is established for epicardial mapping and ablation.

Description

technical field [0001] The invention relates to a dry puncture method for dry pericardium. Background technique [0002] Ventricular tachycardia (referred to as ventricular tachycardia) is a serious rapid arrhythmia, and antiarrhythmic drug treatment is usually ineffective, failing to significantly improve the prognosis and reduce the mortality rate. Transcatheter radiofrequency ablation is one of the effective treatment methods for ventricular tachycardia. However, related studies have found that 5% to 30% of patients with ventricular tachycardia may have lesions originating from the epicardium. Traditional endocardial mapping and radiofrequency ablation cannot be successful, and pericardial puncture is often required for epicardial ablation to succeed. . The conventional route for epicardial ablation is percutaneous subxiphoid pericardiocentesis, but the popularity rate is low, the risk is high, and the operation method is not uniform, especially for dry pericardiocentes...
