Colonoscope

1. A colonoscope comprising:

an image-capturing module comprising:

a casing having a first end and a second end, wherein the first and second ends are spaced from each other in an axial direction of the casing, and wherein the first end is made of a transparent material;

a first image detector arranged at the first end of the casing to provide an illumination effect and to capture a first image in a first direction; and

a vibration motor arranged in the casing and configured to vibrate the casing;

a control unit electrically connected to the first image detector and the vibration motor, wherein the control unit controls the first image detector to capture the first image and controls the transmission of the captured first image upon the reception of a command, and wherein the control unit controls the vibration of the vibration motor; and

a wiring unit fixed to the second end of the casing and comprising an outer sheath and an air tube, wherein the air tube is made of a flexible material and is enveloped in the outer sheath, wherein the wiring unit includes a power supply member electrically connected to the control unit and providing power to the first image detector and the vibration motor,

wherein the casing or the wiring unit includes a vent which is in communication with the air tube of the wiring unit, wherein the air tube is configured to convey an air, and wherein the vent is configured to output the conveyed air to a colon.

2. The colonoscope as claimed in claim 1 , further comprising a second image detector arranged at the second end of the casing, wherein the second image detector is configured to capture a second image in a second direction substantially opposite to the first direction.

3. The colonoscope as claimed in claim 1 , further comprising an angle detection unit electrically connected to the control unit, wherein the angle detection unit is configured to detect an inclined angle of the casing with respect to a horizontal line, and wherein the control unit transmits a detected result of the inclined angle to a display.

4. The colonoscope as claimed in claim 3 , wherein the angle detection unit is a microelectromechanical angle detection chip, a microelectromechanical gyroscope chip, a microelectromechanical dual-axis acceleration detection chip, a microelectromechanical tri-axis acceleration detection chip, a rolling switch or a magnetic sensor.

5. The colonoscope as claimed in claim 1 , further comprising at least one propelling auxiliary arranged on an outer surface of the casing, wherein the at least one propelling auxiliary is configured to facilitate propelling the image-capturing module.

6. The colonoscope as claimed in claim 1 , wherein the power supply member is in a form of a plurality of lead wires contained in the wiring unit.

7. The colonoscope as claimed in claim 1 , wherein the casing has a length of 2.5-5.2 cm and a width of 1.5-2.5 cm.

8. The colonoscope as claimed in claim 1 , wherein the wiring unit or the air tube further comprises an instrument channel provided for insertion of an instrument, wherein the instrument channel has an outlet at the first end of the casing, and wherein the instrument is configured to extend into the instrument channel and extend out of the outlet for performing a surgery.

9. The colonoscope as claimed in claim 1 , further comprising a telescopic propelling control unit connected between the first end and the second end of the casing, wherein the casing has a lateral wall made of a flexible material.

10. The colonoscope as claimed in claim 9 , wherein the casing comprises at least one propelling auxiliary on an outer surface thereof.

11. The colonoscope as claimed in claim 9 , wherein the telescopic propelling control unit comprises a drive motor, a telescopically driving member and a telescopically driven member, wherein the drive motor is mounted to an inner side of the lateral wall, wherein the telescopically driving member is rotatably coupled with the drive motor, and wherein the telescopically driven member is mounted to at least one of the first and second ends.
