Pericardiocentesis needle component

Abstract

Disclosed is a pericardiocentesis needle component (10), comprising a guide wire (13) and a puncture needle (12). The guide wire (13) extends into and through the puncture needle (12), and the guide wire (13) comprises a bent section (32) at the distal end and a straight section at the proximal end. The bent section (32) at the distal end is formed by bending the guide wire (13), and the end of the bent section is a pointed-shape structure. The guide wire (13) is made of a highly elastic material. The pointed end rotates at least 90 degrees within a range of no more than 3 mm starting from the pointed end at the bent section (32) of the guide wire. The pericardiocentesis needle component (10) of the present disclosure is less likely to damage a heart during a pericardiocentesis procedure.

Dependencies are inferred from the claim text.
