10.4 Bronchoscope handpiece with a lever to operate the two-way flexible tip.
Image of 10.5
10.5 Images of a cat’s oesophagus. With a fibreoptic flexible endoscope, pixellation can be reduced by using a filter system in the camera, but the image is still less sharp. Image quality is considerably better with a video-endoscope.

10.6 Examples of ancillary equipment for flexible endoscopes. Biopsy forceps – oval perforated cup with serrated edge; basket forceps; cytology brush; grasping forceps; loop snare; rat-toothed forceps.
Image of 10.7
10.7 Rigid endoscopes with diameters 5 mm and 2.8 mm.
Image of 10.8
10.8 Field of view of a 2.7 mm 30 degrees arthroscope. The field of view delineates the margins of the image that can be seen. The angle of view is the centre of direction of view in relation to the long axis of the endoscope. In this case the centre of the field of view is at 30 degrees to the long axis.
