The application provides an ultrasound-guided puncture method and system, relates to a data processing technology, and achieves accurate positioning during venous puncture under ultrasound guidance by constructing a part model corresponding to a puncture part, determining a partition scanning line of the part model, controlling an ultrasound device to perform segmented scanning on the puncture part based on the partition scanning line, obtaining a segmented scanning image, determining a segmented scanning image meeting a puncture condition as a sub-adaptive image, performing splicing processing on adjacent sub-adaptive images to obtain a spliced puncture image, performing venous shape judgment on the spliced puncture image to obtain a candidate puncture image, performing optimal selection on the candidate puncture image to obtain a puncture guide image, and determining a puncture point of a punctured vein in the puncture guide image based on a centripetal direction.

The application provides a vein data processing method and system based on image analysis, which comprises the following steps: receiving a desired region sequence generated by a user terminal based on a limb model, performing scale conversion on the target limb image of the desired region sequence, generating a target region sequence and sending it to an operation terminal, obtaining a probe position based on a collection device, generating guide information based on the probe position and the relative position of the target region sequence, determining the overlap degree of the probe position and the target region sequence in real time, obtaining a target image based on the overlap degree, when none of the target images meets the puncture condition, processing the target image according to a connectivity strategy to obtain a predicted amplitude and a predicted direction, generating a predicted region sequence based on the predicted amplitude and the predicted direction, and obtaining a recommended point based on the predicted region sequence. The application can meet the personalized puncture requirements of patients while realizing the accurate positioning of the puncture point.
