Abstract:
A terahertz endoscope suitable for intestinal tract lesion inspection and an inspection method are provided. The terahertz endoscope includes a combined tube body inserted into an intestinal tract, a terahertz signal enhancement module, a terahertz inspection module, and a real-time imaging module. The combined tube body mainly includes a sleeve tube ( 6 ), a sleeve head ( 7 ) and a hemispherical glass cover ( 8 ). The terahertz signal enhancement module mainly includes a tunable laser ( 2 ) and an optical fiber ( 9 ) installed in the sleeve tube ( 6 ). The terahertz inspection module mainly includes a terahertz wave detector ( 4 ), a terahertz wave transmitter ( 5 ), as well as a first stainless steel metal wire ( 12 ) and a second stainless steel metal wire ( 13 ) installed in the combined tube body. The real-time imaging module mainly includes an image processing and transmitting circuit board ( 3 ), as well as a power line ( 10 ), a video signal line ( 11 ), an LED cold flight source ( 14 ), and a COMS camera ( 15 ) installed in the combined tube body. The terahertz endoscope and inspection method could be used for accurate inspection of intestinal tract lesions in early stage, thereby improving the inspection accuracy and sensitivity. The terahertz endoscope is capable of obtaining rich information, and has a compact structure, easy operation and wide applicability.

Claim (Index 1):
A terahertz endoscope for intestinal tract lesion inspection, comprising:\n a combined tube body comprising: a sleeve tube ( 6 ), a sleeve head ( 7 ) and a hemispherical glass cover ( 8 ) which are fixedly and axially connected in turn, wherein the combined tube body forms an external shell for inserting in intestinal tract; a terahertz signal enhancement module comprising: a tunable laser ( 2 ) and an optical fiber ( 9 ) provided in the sleeve tube ( 6 ); wherein tunable laser ( 2 ) is configured to generate a wavelength tunable laser beam, wherein the wavelength tunable laser beam is conducted to the sleeve head ( 7 ) via the optical fiber ( 9 ) and irradiated toward an internal wall of the intestinal tract to be tested for enhancing a terahertz signal reflected by the internal wall of the intestinal tract; a terahertz detection module comprising: a terahertz wave detector ( 4 ), a terahertz wave transmitter ( 5 ), and a first stainless steel wire ( 12 ) and a second stainless steel wire ( 13 ) which are both provided in the combined tube body; wherein the terahertz wave transmitter ( 5 ) is configured to generate terahertz wave, wherein the terahertz wave is transmitted by the first stainless steel wire ( 12 ) and then emitted from the sleeve head ( 7 ) towards the internal wall of the intestinal tract, so as to be received and detected by the terahertz wave detector ( 4 ) through a second stainless steel wire ( 13 ) carrying information of internal wall tissue of the intestinal tract to be tested; a real-time imaging module comprising: an image processing and transmitting circuit board ( 3 ), and a power line ( 10 ), a video signal line ( 11 ), a cold LED light source ( 14 ) and a CMOS camera ( 15 ) which are provided in the combined tube body; wherein the image processing and transmitting circuit board ( 3 ) is configured to control the cold LED light source ( 14 ) to emit light to provide a light source for collecting image in the intestinal tract and meanwhile control the CMOS camera ( 15 ) to shoot for obtaining a real-time image; the real-time image is transmitted by the CMOS camera ( 15 ) via the video signal line ( 11 ); wherein the CMOS camera ( 15 ) and the cold LED light source ( 14 ) are connected with a power source via the power line ( 10 ).
