Embodiment

[0044] The principle of photoacoustic imaging: When short-pulse laser irradiates biological tissues, different biological tissues will absorb the pulsed light energy to varying degrees, resulting in instantaneous heating and expansion, thereby generating ultrasonic waves. At this time, the ultrasonic detector located on the surface of the tissue can receive the ultrasonic waves propagating outward in these tissues, and reconstruct the image of the light energy absorption distribution in the tissue according to the detected photoacoustic signal, and obtain the two-dimensional or three-dimensional distribution of the biological internal tissue. image.

[0045] This implementation provides a photoacoustic imaging venipuncture device, such as figure 1 As shown, it includes a controller, a puncture robot arm 4 and a photoacoustic imaging device 6 connected to the first slide rail 7, the puncture robot arm 4 and the photoacoustic imaging device 6 are connected to the controller, and...

Abstract

The invention relates to a veinpuncture device and method. The device comprises a controller, a puncture mechanical arm and photoacoustic imaging equipment connected with a first slide rail, wherein the puncture mechanical arm and the photoacoustic imaging equipment are connected with the controller, and the photoacoustic imaging equipment comprises a short pulse laser generator and an ultrasonictransducer array; and the short pulse laser generator emits short pulse laser to an area to be punctured, the ultrasonic transducer array receives a reflected photoacoustic signal, and the controllergenerates a slice image. Compared with the prior art, the puncture guide imaging depth is increased, the puncture guide imaging resolution is improved, the puncture needle insertion control accuracy is improved, and the to-be-punctured tissue is not damaged.

Description

technical field [0001] The invention relates to the field of venipuncture, in particular to a venipuncture device and method. Background technique [0002] Venipuncture is very common in clinical practice, and its operation puts forward more detailed requirements for medical staff. In assisted puncture and automatic puncture, near-infrared venography and ultrasound venography are widely used, but pure optical imaging such as near-infrared imaging has insufficient penetration, and acoustic imaging does not have high resolution. [0003] At present, the existing automatic or assisted venipuncture equipment cannot perform puncture accurately, resulting in greater risks in the puncture process, and the safety cannot be guaranteed. Contents of the invention [0004] The object of the present invention is to provide a venipuncture device and method in order to overcome the above-mentioned defects in the prior art. [0005] The purpose of the present invention can be achieved t...
