Problems solved by technology

[0003] Aiming at the technical problems existing in the prior art, the technical problem to be solved by the present invention is to overcome the inefficiency of the shock wave triggered by timing trigger or heart rate synchronously triggering on stones, and to provide a method for machine identification of stones by using B-ultrasound images. The method of breathing back to the focus of the wave source ensures that the impact force from the wave source can accurately act on the stones

Embodiment Construction

[0019] The invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, the equipment extracorporeal shock wave lithotripter adopting the inventive method comprises a shock wave source 1, a water bag 2, a B-ultrasound probe 3, an operating bed 4, and the B-ultrasound probe 3 is connected to a B-ultrasound machine 9, and the B-ultrasound machine 9 is connected to a control computer 8 . The cut plane of the B-ultrasound probe 3 intersects the central axis of the wave source in the shock wave source 1 at the focus 5 of the wave source. When the stone drifts out of the wave source focus 5, there is no or very little stone image in the section image of the B-ultrasound probe 3, such as the stone 7 drifting out of the wave source focus. When the stone returns to the wave source focus 5, the B-ultrasound probe 3 A stone image will appear in the section image, such as a stone located at the focal point of the wave sou...

Abstract

The invention relates to a method for B-ultrasonic detection of target stones by an extracorporeal shock wave lithotripter. The focus of the wave source; b. Send the scanning image collected by the B-ultrasound probe in real time to the computer, and set a scanning image of a calculus at the focus of the wave source as a template image; c. The computer compares the real-time scanning image of the B-ultrasound probe with the template image , if the two match, start the shock wave for lithotripsy, then skip to step d, otherwise do not start the shock wave for lithotripsy, and skip to step c; d. Replace the previous template image with the B-mode ultrasound image, and then jump to step c. The beneficial effect of the present invention is: by setting a threshold value for the image deviation, it can be judged whether the calculus has drifted to the focus of the wave source, thereby ensuring that the shock wave emitted by the machine can accurately act on the calculus, improving the therapeutic effect and reducing the surgical injury of the patient , easy to promote.

Description

technical field [0001] The invention relates to the field of extracorporeal shock wave lithotripter medical equipment, in particular to a method for B-ultrasonic detection of target stones by an extracorporeal shock wave lithotripter. Background technique [0002] Extracorporeal shock wave lithotripter is widely used in our country. Its positioning principle mainly relies on B-ultrasound or X-ray images to find stones, and moves human stones to the wave source focus of the wave source through the relative movement of the wave source and the bed, and finally uses the wave source to converge the impact force on the stones to crush the stones. However, in the actual process of lithotripsy, it is found through B-ultrasound images that the stones drift back and forth about 2cm with the patient's breathing relative to the focus of the wave source, so that only about 30% of the shock waves triggered by timing can act on the stones, and the rest of the shock waves will act on the st...
