Abstract
A micro medical-ultrasonic endoscopic OCT probe comprising: a micro ultrasonic motor stator for connecting a friction layer and a magnetic rotor; an ultrasonic transducer and a prism being adhered to a rotor respectively; an acoustic couplant for immersing the ultrasonic transducer; an OCT imaging system consisting of prism, grim lens and fiber. The present invention can not only observe the pathologic changes on the surface of mucosa through endoscope, but can also obtain the histological tomogram of an organ through OCT scan and ultrasonic scan, thus broadening the diagnosis range and increasing the diagnosis ability of endoscopes. The probe of this invention is driven by a micro motor directly mounted on the front end of the probe, and does not need soft wires. Compared with the existing technology, its lifespan is greatly expanded.
