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.
一种新型纤维支气管镜BF - 2.2T已设计完成，它能够通过传统纤维支气管镜（奥林巴斯BF - 1T20）2.6毫米的通道。其外径为2.2毫米；视角为75度，观察范围为3至50毫米，有效长度为1150毫米，全长为1400毫米。它向上弯曲120度，向下弯曲120度。BF - 2.2T 2.2毫米的尖端如同传统纤维支气管镜一样弯曲，这是该仪器的主要特点。作为一种检测周围型肺癌的方法，BF - 2.2T有助于实现临床满意的观察和摄影。
