Diagnosis of peripheral lung cancer using a new type of endoscope.
A new fiberoptic bronchoscope, 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 range of observation of 3 to 50 mm, an effective length of 1,150 mm, and a total length of 1,400 mm. It bends at 120 degrees in an upward direction and at 120 degrees in a downward direction. The 2.2-mm tip of the BF-2.2T bends like a conventional fiberoptic bronchoscope, and this is the main characteristic of this instrument. The BF-2.2T facilitates clinically satisfactory observation and photography, as a method for detecting peripheral lung cancer.
