An endoscope is provided for insertion into a small body cavity like a nostril and a sinus. The endoscope includes a control section, an insertion tube, a working channel tube, and a grip portion. The control section has portions defining a working channel port. The insertion tube extends from the control section and has first and second sections. The proximal end of the second section is connected to a distal end of the first section. The second section is bendable with respect to the first section. The working channel tube is disposed within first and second lumens of the first and second sections, which defines a working lumen extending therethrough. The working lumen is in communication with the working channel port. The grip portion is connected to the control section, and the insertion tube and the control section are rotatable with respect to the grip portion. |
