Focus-adjustable photoacoustic dual-mode endoscopic probe

Abstract

The invention discloses a focus-adjustable optoacoustic bi-mode endoscope probe. The focus-adjustable optoacoustic bi-mode endoscope probe comprises an ultrasonic transducer, an incident optical fiber and a conical reflector, wherein a hemispherical inwards-concave face is arranged at the inner side end of the ultrasonic transducer and set to be an ultrasonic probing receiving face; the emergent light of the incident optical fiber axially penetrates through the ultrasonic transducer to irradiate the sphere center of the hemispherical inwards-concave face; the reflection conical face of the conical reflector is axially and rotationally arranged on the sphere center of the hemispherical inwards-concave face, and the incident light of the incident optical fiber is reflected through the reflection conical face and then is perpendicularly emit to the part to be detected from the side wall of an endoscope; at least one ultrasonic vibration element is arranged on the inwards-concave face of the outer side of the center of the hemispherical inwards-concave face, the ultrasonic waves sent by the ultrasonic vibration elements are reflected through the reflection conical face and then is obliquely emit to the part to be detected from the side wall of the endoscope, and the emitting ends of the ultrasonic vibration elements are rotationally arranged on the hemispherical inwards-concave face. The focus-adjustable optoacoustic bi-mode endoscope probe solves the technical problem that an endoscope probe cannot carry out deep imaging analysis on an infected part.

Description

technical field [0001] The invention relates to the technical field of biomedical devices, and more specifically, the invention relates to a focus-adjustable photoacoustic dual-mode endoscopic probe. Background technique [0002] The currently commonly used optical endoscopes are mainly NDT instruments integrating light, machinery and electricity, which are divided into three series of products: the first category, rigid endoscope series; the second category, fiber endoscope series; the third category Three types, electronic video endoscope series. The working principle of the rigid endoscope series is to use the image transfer lens optical technology to transmit the image, and the optical fiber provides light transmission and illumination. The working principle of the fiber endoscope series is to transmit images through high-quality image-transmitting fibers, and observe them directly through the eyepiece. The electronic video endoscope series is to manufacture electronic...
