Description

Infrared real-time ultrasonic guiding device

Technical Field

The utility model relates to a medical equipment technical field, more particularly, the utility model relates to a real-time supersound guiding device of infrared ray.

Background

The concept of interventional ultrasound (interventional ultrasound) was first proposed by the Copenhagen world interventional ultrasound academy in 1983.

Currently, the following are commonly used: various ultrasound-guided punctures and treatments (needle biopsy, aspiration, drainage, drug infusion, microwave and radiofrequency treatments, etc.), intracavity ultrasound (intravascular ultrasound, transrectal ultrasound, transvaginal ultrasound, ultrasound gastroscope, etc.), intraoperative ultrasound, sonography, high-intensity focused ultrasound, and the like.

The advantages of ultrasound-guided puncture are: the guidance is accurate; the method is simple and convenient: popularization, simplicity and convenience; safe and reliable: the whole process of the ultrasonic guided puncture is carried out under the real-time monitoring of the ultrasonic, the needle inserting process of the puncture needle can be observed, the damage to the large blood vessel and the adjacent important structure can be avoided, and the complication can be reduced; the cost is low: compared with CT and MRI (magnetic resonance imaging), the ultrasonic guide puncture cost is low, the cost performance is high, the medical cost is reduced, and the economic burden of a patient is reduced.

In order to ensure that a safe puncture path can be selected in advance, a puncture needle is monitored and guided to accurately reach a target focus, and the safety and the accuracy of puncture are obviously improved, the current ultrasonic puncture technology is that a probe is mostly provided with a puncture frame for guiding, the puncture frame is matched with a guide wire on a display for puncture operation, and the method is a puncture method which is frequently adopted at present and is also the most satisfactory ultrasonic technology and is used as a preferred method of interventional ultrasound. The sterilized puncture frame is arranged on the probe during puncture, the device is provided with a needle passage to ensure that the puncture needle can penetrate through and keep stable in a puncture area, and a guide line on the display can guide a puncture path. The technology enables the puncture needle to accurately penetrate into tissues along the path of the guide wire, can display the puncture process in real time, enables puncture to be standardized, improves safety and efficiency, and meanwhile, greatly helps to popularize the ultrasonic intervention technology.

However, for some parts with complicated structures, such as thyroid gland, joint cavity of narrow part, nerve block of complicated part, etc., the path of the puncture needle needs to be adjusted at any time during the needle inserting process, in this case, the puncture frame with fixed path is generally not recommended to be used, so as not to limit the adjustment of the puncture needle. This requires a free-hand puncture technique under ultrasound guidance, the puncture needle is penetrated subcutaneously and then the puncture needle continues to puncture the focus of the person, without the guidance of a puncture frame in the process. The puncture needle and the ultrasonic probe are separated, the ultrasonic probe can be moved at will to display the focus, and the puncture needle can puncture at any angle, so that the puncture method is a bare-handed puncture method. However, the outstanding problem in the manual puncture method is that: the puncture needle is not easy to display, more experience is needed, the accuracy is limited, and an operating doctor has to repeatedly adjust the position of the puncture needle to well display the needle path, so the technology only has a certain effect on the puncture of superficial tissue structures or large focuses. The ultrasonic guided bare-handed puncture technology is mostly applied to emergency treatment, bedside operation and the like, and is relatively difficult to guide for clinicians with lack of ultrasonic experience.

Therefore, an ultrasonic guiding device which is suitable for complex parts and is accurate in positioning is needed.
