Endoscope drive device and endoscope system

The invention discloses an endoscope drive device and an endoscope system. The endoscope drive device comprises a shell, a motor and at least one transmission mechanism, wherein the input end of the transmission mechanism is connected with the motor, the output end of each transmission mechanism is used for being connected with the linear transmission part of an endoscope, each transmission mechanism can convert the rotation motion of the motor into linear motion, and each transmission mechanism drives the linear transmission part of the endoscope so as to allow one side of the end of the endoscope to bend. The motor is internally provided with or externally connected with a rotation angle detecting device, and the rotation angle detecting device is used for detecting the rotation angle of the motor and transmitting the rotating angle to a processor so as to allow an image processing device to conveniently calculate the bending angle of the end of the endoscope. The image processing device calculates the bending angle of the endoscope according to the measured rotation angle of the motor and displays the bending angle on a display terminal, so that an operator can accurately learn about the current bending angle of the endoscope, and the operator can perform corresponding operation on the basis of the bending angle.
