[Diagnosis of peripheral-type lung cancer using a new type of endoscope].
A new device, the BF-2.2T, has been designed to go through the 2.6 mm channel of the conventional fiberoptic bronchoscope (Olympus BF-1T20). It measures 2.2 mm in outer diameter; it has a visual angle of 75 degrees, a focal depth of 3 to 50 mm, a working length of 1150 mm, and a total length of 1400 mm. It bends 120 degrees in an upward direction and 120 degrees in a downward direction. The tip, 2.2 mm phi, of the BF-2.2 T angulates like a conventional bronchofiberscope, and this is the main characteristic of this instrument. The BF-2.2 T yields clinically satisfactory observation and photography, as a method for determining morphological changes in peripheral type lung cancer.
