Ultrasonic-Doppler-effect positioning puncturing device for vessel

Abstract

The invention relates to an ultrasonic-Doppler-effect positioning puncturing device for the vessel. The device comprises an ultrasonic probe, a main control system and a puncturing device. The puncturing device comprises a support, a needle tube, a puncturing needle, a first coder and a second coder. The support is installed on the ultrasonic probe, the front end of the needle tube is installed infront of the support in a rotatable mode, an arc-shaped groove is formed in the rear of the support, and a guide rod is arranged at the rear end of the needle tube and located in the arc-shaped groove. The first coder is installed on the side wall of the needle tube, the second coder is installed on the guide rod, and the ultrasonic probe, the first coder and the second coder are electrically connected with the main control system. Due to the fact that the first coder and the second coder are arranged, through linkage between the needle tube and the ultrasonic probe, needle insertion is guided according to a puncturing range, a puncturing thread, angle information and depth information, the puncturing angle and puncturing depth of the puncturing needle are accurately controlled, it is ensured that a needle head of the puncturing needle accurately reaches the vessel of a focus part, then puncturing work is finished in a one-off mode, and the ultrasonic-Doppler-effect positioning puncturing device is safer and more reliable.

Description

technical field [0001] The invention relates to a medical puncture device, in particular to an ultrasonic Doppler effect vessel positioning puncture device. Background technique [0002] At present, it is often necessary to puncture the lesion of the patient in medical treatment, so as to perform operations such as inspection and sampling of the lesion. [0003] In order to make the puncture accurate, Doppler ultrasound positioning technology is usually used at present, that is, the ultrasonic probe is used to detect the lesion position on the patient's body, and then the doctor holds a puncture device including a needle barrel and a puncture needle for puncture. During the puncture process (including needle insertion) , needle stop, needle withdrawal), only based on the doctor's feeling and experience, there is no accurate puncture angle and puncture depth information. Case. If the puncture is not in place, the purpose of inspection and sampling cannot be achieved, and a ...

[0003] In order to make the puncture accurate, Doppler ultrasound positioning technology is usually used at present, that is, the ultrasonic probe is used to detect the lesion position on the patient's body, and then the doctor holds a puncture device including a needle barrel and a puncture needle for puncture. During the puncture process (including needle insertion) , needle stop, needle withdrawal), only based on the doctor's feeling and experience, there is no accurate puncture angle and puncture depth information. Case

If the puncture is not in place, the purpose of inspection and sampling will not be achieved, and a new puncture will be required, which will undoubtedly increase the pain and psychological burden of the patient

Puncturing a blood vessel causes tissue damage and also requires repunching
