Optical fiber opto-acoustic guide surgical device

The invention belongs to the technical field of surgical equipment, and discloses an optical fiber opto-acoustic guided surgical device which comprises an opto-acoustic positioning module, an ultrasonic detection module and a virtual visual display module. The photoacoustic positioning module is used for positioning the positions of a focus and a scalpel and sending a photoacoustic signal to the ultrasonic detection module, and the ultrasonic detection module is used for obtaining the photoacoustic signal sent by the photoacoustic positioning module and conducting image registration on the photoacoustic signal and a preoperative CT/MRI image and conducting image registration on the focus and the scalpel during an operation; and the virtual visual display module is used for emitting a laser trigger signal to the photoacoustic positioning module, displaying an intraoperative image of the ultrasonic detection module and prompting a distance range between a focus and the scalpel. The photoacoustic effect is utili
