Embodiment Construction
[0029] A very important issue in freehand puncture is to maintain the accuracy of the needle path and to select a suitable puncture point, but these are inseparable from the support of imaging equipment. When B-ultrasound and color Doppler ultrasound are used for exploration before puncture, the ultrasonic probe will eventually reach the target position to be punctured during the movement process. At this time, the doctor needs to determine the puncture position and needle angle by looking at the monitor. However, due to the lack of a good force point during the freehand puncture process, even with the guidance of the detected image, the needle path will still deviate; while the ultrasound equipment detection image is only a limited fan-shaped surface on the display, and the needle path is slightly deviated The needle is no longer visible and needs to be corrected or repunctured.
[0030] The idea proposed by the inventor in this solution is that most of the reasons for the de...
