Flexible steering mechanism and endoscope using same

The utility model belongs to the technical field of medical equipment, and relates to a flexible steering mechanism which comprises a fixing head and a transition block arranged above the fixing head through a balancing frame, a plurality of air bag hoses are arranged between the transition block and the fixing head, a universal ball valve is arranged between the transition block and the balancing frame, and the air bag hoses are connected with the universal ball valve. And the transition block can be driven to realize flexible steering movement around the universal ball valve by controlling the air pressure of different air bag hoses. The balancing frame serves as a supporting frame and is matched with the universal ball valve and the air bag hose to achieve steering action of the transition block, so that steering adjustment of the endoscope is achieved, and the endoscope steering device has the advantages of being simple in structure, convenient to operate, capable of saving cost and the like.
