Abstract
The invention relates to the technical field of surgical positioning, in particular to a puncture needle positioning system and method, and a method and device for obtaining the axis of an ultrasound probe as projected onto an ultrasound image. The puncture needle positioning system includes: an ultrasound unit including a first probe for providing an ultrasound image of a lesion, and a plurality of first positioning devices for providing coordinate information of the first probe are provided on the first probe; the needle unit includes a puncture needle. The puncture needle is provided with a plurality of second positioning devices for providing coordinate information of the puncture needle; a processing and display unit is connected to the ultrasound unit, each of the first positioning devices, and each of the second positioning devices. The puncture needle positioning system improves the accuracy of transthoracic puncture, thereby avoiding complications caused by repeated puncture.
