Safe pericardiopuncture device and use method thereof

Abstract

The invention discloses a puncture needle. The puncture needle consists of a needle body and a needle seat, wherein a head end of the needle body bends laterally, a needle hole is formed in the bent inner side surface and is vertical to a vertical axis of the needle body, and a needle tip is of an arc-shaped cutting surface. Accordingly, the inventor further designs a guide wire flipping sender matched with the puncture needle for use, and the puncture needle and the guide wire flipping sender form a safe pericardiopuncture device. By virtue of the puncture needle with a lateral opening, the acutance of a tip of the puncture needle can be decreased, the direction of an outlet is changed, and risks that the heart is punctured by the puncture needle and a guide wire are reduced; the guide wire flipping sender is matched with the puncture needle for use, and the guide wire can be automatically sent into a pericardial cavity from the lateral needle hole at the moment that the needle hole completely enters the pericardium, so that the situations that the heart is punctured by the needle tip when the puncture needle is shaken by accident, and the guide wire is directly flipped to the heart are avoided, and instant protection of the heart is realized. Therefore, the safe pericardiopuncture device can be used for conveniently and rapidly carrying out pericardiopuncture and is safe, stale and reliable.

Description

Technical field [0001] The invention belongs to the technical field of pericardiocentesis, and in particular relates to a safe pericardiocentesis device and a method of use thereof. Background technique [0002] Pericardiocentesis is an important method for clinical diagnosis and treatment of pericardial effusion and epicardial ablation of ventricular arrhythmia. The risk of pericardiocentesis is higher due to the narrow pericardial cavity, narrow puncture safety window, proximity to important organs, heart beating, and dense coronary arteries and veins on the surface of the heart. Traditional pericardiocentesis is easy to damage the heart and its blood vessels and adjacent organs, and can cause complications such as acute pericardial tamponade, blood pneumothorax, abdominal organ injury, lung injury, etc. In severe cases, pericardial drainage, blood transfusion, thoracotomy, abdominal exploration, etc. Surgical repair of tissue organs, etc., cause significant damage and economi...

Problems solved by technology

[0008] The common feature of the above-mentioned puncture needles is that the tip is sharp and lacks a protective mechanism, which can easily puncture the heart and its blood vessels, causing a series of complications
