Multifunctional puncture guide wire leading-in device

Abstract

The invention relates to the technical field of puncture devices, in particular to a multifunctional puncture guide wire leading-in device. The device comprises a guide wire channel, a puncture needle connecting pipe, a liquid inlet pipe, a flow stopping clamp, a three-way connector and a liquid supply positive pressure valve; an upper end opening of the guide wire channel is in a horn shape, and the lower end of the guide wire channel is connected with the puncture needle connecting pipe. The lower end of the liquid inlet pipe is connected to the side wall of the guide wire channel, and the liquid inlet pipe is communicated with an inner cavity channel of the guide wire channel. The flow stopping clamp is connected to the liquid inlet pipe, and an upper end opening of the liquid inlet pipe is connected with a first end opening of the three-way connector. And the liquid supply positive pressure valve is connected to a second port of the three-way joint. The guide wire leading-in device can avoid the situation that a guide wire is difficult to place due to the fact that needle point displacement is prone to occurring in the traditional two-step puncture process, the requirement for the operation skill of an operator is low, and the guide wire leading-in device has more advantages on puncture of a fine part.

Description

technical field [0001] The invention relates to the field of puncture devices, in particular to a multifunctional puncture guide wire introduction device. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] Percutaneous puncture catheterization is one of the important auxiliary means in modern interventional therapy technology, and has been widely used in medical technologies such as puncture of pipelines, hollow organs, hemodialysis, and catheter drainage. The commonly used percutaneous catheterization in clinical operations is a two-step method. When using this method, it is necessary to enter the target site through percutaneous puncture first, then indwell a...

Problems solved by technology

However, the inventors found that this two-step method has the problem that the needle tip is prone to displacement during the operation, which may lead to difficulties in inserting the guide wire and certain difficulties in puncturing delicate parts. In addition, the puncture needle sometimes displays In a word, these deficiencies make the existing percutaneous puncture catheterization require higher operating skills of the operator, and it is easy to bring hidden dangers
