Novel artery puncture trocar

Abstract

The invention relates to a novel artery puncture trocar, which comprises a needle tube and a core, wherein one end of the core is connected with a detachable handle, and a core cap is connected on the handle; the needle tube can be penetratively sleeved outside the core in a replaceable way, and tip of the core is exposed out of the needle tube. The novel artery puncture trocar has the beneficial effects of high puncture success ratio, and safer and more convenient puncture.

Description

technical field [0001] The invention relates to a medical device, in particular to a novel arterial puncture trocar which can be used for radial artery and femoral artery puncture. Background technique [0002] At present, the radial artery puncture catheter is often used in clinical monitoring of direct arterial blood pressure, and the puncture needle is a 20GA trocar. In case of massive bleeding, emergency rescue, etc., the radial artery cannot be touched or dissected aneurysm, etc. It is necessary to open the lower extremity artery (often the femoral artery). Because of the deep position of the femoral artery, the part of the 20GA trocar entering the blood vessel is limited, and the puncture needle often slips and is difficult to fix. However, there is currently no dedicated femoral artery puncture needle. In addition, during puncture, it is often encountered that the blood return of the needle core is very good, but the needle tube is damaged and hairy and cannot be inse...

Problems solved by technology

[0003] The present invention solves the problem that the existing puncture needle needs to be re-punctured when the needle tube is damaged, and provides a new arterial puncture trocar that does not need to be re-punctured when the needle tube is damaged.
