The invention belongs to the field of medical appliances, and particularly relates to an intelligent electronic endoscope system passing through natural orifices. The intelligent electronic endoscope system is suitable for a colposcope system, an anorectal endoscope system and a hysteroscope system, and comprises an electronic endoscope, an endoscope clamping mechanical arm for fixing the electronic endoscope, a movable adjustment operating platform, an intelligent robot-arm, a control desk and a central processing system, wherein the tail end of the main body of the endoscope is provided with a linear type robot-arm passage running through a hard working end part. By using the intelligent electronic endoscope system, a patient needs no operation, only the electronic endoscope is put inside through the natural orifices, and the intelligent robot-arm is put into an operation area by taking the intelligent robot-arm passage of the electronic endoscope as a platform; and the intelligent robot-arm is miniaturized, deformable and direction-changeable and simultaneously is provided with functions of a plurality of operative instruments (such as operative snap-on tongs, electric cutting equipment, electric coagulation equipment and the like), and thus, various operation treatments can be performed without introducing other instruments, and the difficulty of operations and the paint of patients are reduced.
