Disposable endoscope

An orientation controller to be connected to an insertion unit of an endoscopic device having a rotatable bending section;

• said controller comprises:
• a handle defining an axial direction to be handled by an operator;
• a rotatable bearing structure connecting between the handle and the insertion unit;
• wherein said rotatable bearing structure is configured and operable to rotate the rotatable bending section of the insertion unit about the axial direction;
• and
• a mode selector capable of operating the endoscopic device in having a locked mode and unlocked operation modes, wherein operation of the locked operation mode blocks the rotatable bearing structure, and operation of the unlocked mode allows the operator to rotate the rotatable bending section by rotating the rotatable bearing structure about the axial direction;
• wherein, when the insertion unit comprises an inner elongated shaft structure and an outer elongated shaft structure surrounding the inner elongated shaft structure;
• said rotatable bearing structure comprises an inner rotatable bearing element being configured for holding the inner elongated shaft structure, and an outer rotatable bearing element connected to the outer elongated shaft structure such that the inner rotation bearing element is capable of rotating within the outer rotatable bearing element, thereby rotating in the unlocked operation mode the rotatable bending section around itself without changing the outer elongated shaft structure's position inside the body lumen.
