Embodiment 1

[0037] A puncture device based on ultrasound guidance, comprising a puncture needle module 3, a puncture area sensor 2, and a processor 4; the puncture area sensor 2 is connected to the processor 4; the puncture needle module 3 includes an optical fiber vibration sensor capable of measuring vibration.

[0038] The ultrasound-guided puncture device also includes an ultrasound probe 1 and an ultrasound host 5, and the ultrasound probe 1 and the ultrasound host 5 are connected.

[0039] The ultrasound host 5 includes an ultrasound imaging module, an ultrasound host processor and a display.

[0040] Further, the ultrasonic probe 1 transmits ultrasonic waves to the puncture needle and the puncture area and receives ultrasonic echoes, the ultrasonic host processor calculates the position data of the puncture needle and the puncture area, and the ultrasonic host processor calculates the position data of the puncture needle relative to the puncture area. The puncture point is calculat...

Embodiment 2

[0046] The present invention also provides a method for catheterization based on ultrasound guidance, using the above-mentioned device, comprising the following steps:

[0047] Step 1. Before puncture, use the ultrasonic probe 1 to locate a suitable puncture position, move the puncture area sensor 2 to the puncture position, and obtain the initial signal of the puncture area;

[0048] Step 2. During puncture, obtain the position of the puncture needle through the ultrasonic probe 1 to determine the position of the puncture point, plan the virtual navigation puncture route of the puncture needle according to the position of the puncture point and display it on the ultrasound host 5;

[0049] Step 3. The puncture needle performs puncture according to the virtual navigation puncture route in step 2. When the puncture needle enters the puncture area, the signal acquired by the puncture area sensor 2 changes, and the display on the ultrasound host 5 prompts; at the same time, monito...

Abstract

The invention discloses a puncture device based on ultrasonic guidance. The puncture device comprises a puncture needle module, a puncture area sensor and a processor. The puncture area sensor is connected with the processor; the puncture needle module comprises an optical fiber vibration sensor capable of measuring vibration. Accurate position data of response of human tissue to the puncture needle in the puncture process is obtained, and the success rate of catheterization under ultrasonic guidance is increased.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an ultrasound-guided puncture device and method. Background technique [0002] Ultrasound-guided cannulation can visually display the puncture needle, blood vessels and the surrounding environment of blood vessels. Ultrasound-guided cannulation has the advantages of real-time guidance, full visibility, shortened puncture time, and reduced complications. It can not only reduce the pain of puncture patients, At the same time, it provides a safe and effective infusion route for nursing staff. But how to improve the success rate of catheterization is a problem we need to solve. [0003] In the existing technology, such as figure 1 As shown, the application number is 201610347648.5, which discloses a real-time puncture navigation system and its navigation method, which includes: a puncture needle, and a host computer displaying multimodal images based on the fusion of preoperative mag...
