Abstract

Provided are an ultrasound intervention puncture device and a puncture assembly. The ultrasound intervention puncture device comprises an ultrasonic probe and a puncture assembly. The puncture assembly comprises a telescopic puncture needle, a first channel, and a third channel. One end of the first channel is connected with the puncture needle, and the other end is provided with a first pressure sensor. The first pressure sensor is used to detect pressure of liquid in the first channel, to obtain a first pressure value. One end of the third channel is connected with the puncture needle, and the other end is provided with an input control portion used to control a catheter conducting wire to stretch. If the first pressure value reaches a first preset pressure threshold, the input control portion controls the catheter conducting wire to extend into the puncture needle from the third channel. Through combining the ultrasonic probe with the puncture assembly which is provided with three channels, the device can accurately position puncture positioning points of an intervention puncture object, and each component is intelligently controlled through a control unit, so that steps of puncture operation are simplified, and puncture efficiency is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an ultrasonic interventional puncture device and a puncture assembly. Background technique [0002] Interventional puncture refers to various minimally invasive and invasive operations performed by inserting puncture needles, catheters, etc. into the patient's body for the purpose of diagnosis or treatment. At present, puncture needles, catheters, guide wires and other materials are mainly used clinically to insert them through blood vessel puncture, and the needles are withdrawn intermittently until bright red arterial blood can be seen ejecting from the tail of the needle, followed by dark red venous blood dripping out slowly. At this time, the guide wire can be fed to the designated position and then the catheter can be inserted. After the guide wire is withdrawn, the puncture is completed. [0003] The aforementioned interventional puncture methods have the following defects: ...
