摘要:
A photoacoustic-ultrasonic dual-mode endoscope includes: a probe and a probe driving unit, wherein the probe includes: a coaxially configured optical and electromagnetic rotary waveguide assembly including an optical fiber, the optical fiber including a core and a cladding, and a conductive path coaxially arranged with the optical fiber; a scanning tip located at an end of the coaxially configured optical and electromagnetic rotary waveguide assembly and configured to deliver a laser beam to an object to be examined and detect a photoacoustic signal and an ultrasonic signal generated from the object to be examined; and a plastic catheter surrounding outer surfaces of the coaxially configured optical and electromagnetic rotary waveguide assembly and the scanning tip, wherein the conductive path includes: a first conductive path including a portion coaxially arranged with the optical fiber; and a second conductive path including a portion coaxially arranged with the optical fiber and insulated from the first conductive path.
