Technical Field

The invention relates to a puncture tool, in particular to a guide wire-needle head integrated arteriovenous puncture device capable of being operated by one hand.

Background

The blood vessel puncture sheath is a necessary appliance in interventional operation and is used for completing arteriovenous puncture, establishing a passage by a guide wire and introducing a sheath tube. However, in the current puncture method, a hollow puncture needle is used to puncture a target blood vessel, after bleeding is observed, a puncture needle core is removed, a guide wire is placed, the puncture needle is removed, a sheath tube is introduced along the guide wire, and sheath placement is completed.

However, during operation, since the (one) guide wire is separated from the puncture needle: 1. a lot of blood can flow out to cause unnecessary blood loss of the human body; 2. if the patient moves or the operator does not control the puncture needle well, the puncture needle is easy to shift, and when the guide wire is introduced, the needle point is already separated from the target blood vessel, so that the puncture is failed. And (II) the operation can not be carried out by one hand, the operation of halfway hand changing or assistant cooperation is needed, the operation is complicated, and the time is delayed.
