Ultrasound diagnostic equipment

Abstract

To provide an ultrasound diagnostic device that makes it easier for users to perform punctures on subjects. [Solution] An ultrasound diagnostic device 1 that assists in inserting a puncture needle QT into a subject's HT comprises an ultrasound probe 20, an optical camera 30 attached to the proximal end of the ultrasound probe 20 for capturing images of the state in which the puncture needle QT is inserted into the subject's HT, an optical image analysis unit 15 that detects the posture of the puncture needle QT by analyzing the optical image acquired by the optical camera 30, and a mispuncture determination unit 17 that determines the occurrence of mispuncture of the puncture needle QT based on the detected posture of the puncture needle QT and a pre-stored target posture of the puncture needle QT.

Claims

1. An ultrasound diagnostic device that assists in puncturing a subject, Ultrasound probe and An optical camera that photographs the state in which the puncture needle is inserted into the subject, An optical image analysis unit detects the orientation of the puncture needle by performing image analysis on the optical image acquired by the optical camera, A memory unit that stores the target orientations of multiple puncture needles in advance, A selection unit that selects one target posture from a plurality of target postures of the puncture needle stored in the memory unit, A mispuncture determination unit determines the occurrence of a mispuncture of the puncture needle based on the detected orientation of the puncture needle and the target orientation of the puncture needle selected by the selection unit, An ultrasound diagnostic device equipped with the following features.

2. The target orientations of the multiple puncture needles are stored in the storage unit in correspondence with the types of the multiple puncture needles. The ultrasound diagnostic apparatus according to claim 1.

3. The ultrasound diagnostic apparatus according to claim 1, further comprising a notification unit that prompts the user to correct a puncture when the erroneous puncture detection unit determines that an erroneous puncture has occurred.
