Abstract: A separable-type endoscope imaging system includes a first body portion, a flexible hollow detection tube, and a second body portion. The first body portion includes an output terminal and a wireless transmitter unit. The flexible hollow detection tube is located at one end of the first body portion and internally provided with a lens assembly for generating an image signal. The second body portion includes an input terminal, a wireless receiver unit, and a display unit. When the output terminal is electrically connected to the input terminal, the image signal is transmitted via the output terminal and the input terminal to the display unit for displaying. On the other hand, when the output terminal is not electrically connected to the input terminal, the image signal is wirelessly transmitted from the wireless transmitter unit to the wireless receiver unit for displaying on the display unit.
