| titleOfInvention | Photoacoustic endoscope based on self-adaptive focusing of light-transmitting and sound-transmitting water bag and implementation method |
| abstract | The invention discloses a photoacoustic endoscope based on self-adaptive focusing of a light-transmitting and sound-transmitting water bag and a realization method, wherein the endoscope comprises the following components: the device comprises a probe module, a control module and a display module; the probe module comprises a water bag, a hollow annular ultrasonic transducer, an optical assembly, a rotating shaft, an outer sleeve and a handle, wherein the optical assembly comprises a glass column, a reflector with an angle of 45 degrees, a zoom lens, a collimating lens and an optical fiber, the outer sleeve injects water into the water bag through a water injection channel, and a motor and an electric slip ring which are contained in the handle control the probe to rotate; the control module comprises a motor drive, a laser drive, a zoom lens drive and a data acquisition card; the display module includes a computer. According to the invention, the water sac is flexibly matched with the intestinal cavity with an irregular shape, and the boundary of the intestinal cavity is accurately determined by using the photoacoustic signal of the water sac, so that the multilayer structure of each circle of the intestinal wall at different angles is in focus when the probe is circularly swept for 360 degrees, and thus, an image with high resolution and high contrast is obtained. |
