[0034] Example
[0035] like figure 1 , figure 2 and image 3As shown, a photoacoustic endoscope with high-precision front three-dimensional scanning includes a probe shell 1, a micro-motor placement cavity 1-1, an oil chamber 1-2, a cavity 1-3, an optical reflection prism 2, and a micro-motor 3. Ultrasonic transducer 4, optical zoom lens 5, fiber bearing 6, fiber 7, laser beam 8.
[0036] The probe shell 1 is provided with a micro-motor placement cavity 1-1, an oil chamber 1-2 and a cavity 1-3, the micro-motor placement cavity is set at the front end of the probe shell, and the oil chamber is set in the probe. In the middle position inside the shell, the cavity is arranged at the rear end inside the probe shell.
[0037] The ultrasonic transducer 4 is installed in the middle position inside the probe shell 1, and separates the oil chamber 1-2 and the cavity 1-3; the optical zoom lens 5 is arranged at one end of the cavity close to the ultrasonic transducer, and the micro...
