| abstract |
The present invention relates to a flexible-tubed structure of an endoscope comprising a plurality of cylindrical units (11), a first wire (31), a second wire (32), a first flexible unit (21), and a second flexible unit (22). The wires (31, 32) respectively pass through the cylindrical units (11). The flexible units (21, 22) are continuously disposed at the recesses (112, 113, 114, 115) of the cylindrical units (11). The cylindrical units (11) are used to form a tubular unit (1) by the flexible units (21, 22). The tubular unit (1) is bent by the tension of the first wire (31) or the second wire (32) to control the turning-direction (61, 62, 63, 64) of the camera apparatus (4). |
