Puncture needle kit assembly and use method thereof

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a puncture needle suite assembly and a using method thereof.The puncture needle suite assembly comprises a puncture needle suite assembly body and a hose, the puncture needle suite assembly body is composed of a puncture sheath, a blood vessel dilator, an obturator, a miniature guide wire and a puncture needle, and a third hollow pipe is fixedly installed at one end of the hose; a first hollow tube is fixedly installed on the inner wall of the top end of the puncture needle, the inner wall of the first hollow tube is detachably connected with a third hollow tube through a fixing structure, and a sealing structure is arranged at one end of the puncture needle. Compared with the prior art, the tail end of the puncture needle is prevented from being injected into a contrast agent, so that the phenomenon that the puncture needle moves is avoided, and the situation that blood cannot be seen after blood return is punctured is avoided, so that great convenience is brought to medical staff.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a puncture needle kit assembly and a method of using the same. Background technique [0002] Interventional therapy is a minimally invasive treatment using modern high-tech means, that is, under the guidance of medical imaging equipment, special puncture needle kit components (such as catheters, guide wires and other precision instruments) are introduced into the human body. Diagnose and treat locally. [0003] At present, when the guide wire enters the blood vessel through the puncture needle, the phenomenon that the guide wire cannot enter the blood vessel easily occurs. The existing solution is generally to inject a contrast agent at the tail end of the puncture needle, so as to observe the blood vessel shape. , but this will easily make the puncture needle move. Since some blood vessels are very thin, after the puncture to return blood, if the puncture needle moves, ...

AI Technical Summary

Problems solved by technology

[0003] At present, when the guide wire enters the blood vessel through the puncture needle, it is easy for the guide wire to enter the blood vessel poorly. The existing solution is generally to inject a contrast agent at the end of the puncture needle to observe the shape of the blood vessel. , but this will easily cause the puncture needle to move. Because some blood vessels are very thin, if the puncture needle moves after puncture to blood return, blood will not be visible, and the current guide wire is thicker and thicker. Hard phenomenon, if the blood vessel is thin and twisted, it is difficult for the guide wire to enter the blood vessel
