Ultrasonic guiding auxiliary device and system for needle

Abstract

The invention provides an ultrasonic guiding auxiliary device for a needle. The ultrasonic guiding auxiliary device includes a probe for transmitting an ultrasonic signal to a tissue to be punctured and injected and receiving an ultrasonic signal from the tissue to be punctured and injected, a first mechanical arm used for moving a probe to the tissue to be punctured and injected, a second mechanical arm for fixing the needle for puncturing and moving the needle to be close to the tissue to be punctured and injected and then causing the needle to penetrate into the tissue to be punctured and injected, and a host, wherein the host controls the first mechanical arm to move the probe to the tissue to be punctured and injected, and the probe transmits and receives the ultrasonic signal; the host synthesizes an ultrasonic image through the ultrasonic signal transmitted by the probe; the host at least calculates a puncture distance between the needle and the tissue to be punctured and injected and a puncture angle through the ultrasonic image; and the host controls the second mechanical arm to move the needle to the corresponding puncture distance and puncture distance according to the puncture distance and the puncture angle and then performs puncture. The ultrasonic guiding auxiliary device is used for guiding the accurate puncture of the needle.

Description

technical field [0001] The invention relates to a medical guidance auxiliary device and system, in particular to a medical ultrasound guidance auxiliary device and system. Background technique [0002] At present, the application of ultrasound equipment in clinical diagnosis and treatment has been very popular, and it has made great contributions to doctors' accurate understanding of patients' conditions, formulation of medical plans and adjuvant treatment. [0003] At present, ultrasound has been widely used for puncture guidance, but manual puncture is still performed after the probe is manually scanned on the surface of the tissue to be measured by the ultrasound probe, and then the ultrasound image is manually used to determine the depth of blood vessels and other tissues. This requires three manual judgment operations, such as how to quickly scan the effective area with the ultrasound probe, how to judge the depth of blood vessels and other tissues on the ultrasound ima...

Problems solved by technology

However, conventional intravenous injection (such as drip) has not yet been guided by ultrasound in the market. Intravenous injection is the most routine work in hospitals or clinics. Doctors or nurses need to perform a large number of intravenous injection operations every day. Because of human experience, it is inevitable. It often happens that the intravenous injection fails due to the negligence or misjudgment of the doctor or nurse during the intravenous injection, such as the intravenous needle piercing the blood vessel, or choosing a very thin blood vessel, or the wrong angle of the intravenous injection causing the intravenous injection Stability of fluid entry into any vessel or tissue
