Function Characteristics:
The outside diameter of insert tube of the nasopharyngoscope is 6mm. And the insert tube has good interpolating function. The corner piece part of the endoscope could be upward 130°, downward 90°, and the field lens’s view angle is 100°, then it could get to the observed part fast and smoothly to inspect pathological changes.
The endoscope uses the operating grip with all-plastic shell, reasonable platinum hole position. There is a hole with 2mm diameter, which is used to attack and ensure the free flowing of forceps and other instruments. The thump-operated attracting valve is convenient. It could be dismantled, safe and reliable.
The enlargement ratio is 25 times. The large depth of focus, wide visual angle and round field coverage make it sure to view clear images within 3750mm, and even the tiny pathological changes would not be missed. If user wants to get better product, then D image-carrying fiber could be assembled, and a better image effect could be get.
Product Use:
ANF-6 type fiberoptic nasopharyngoscope is suitable for inspecting pathological changes in E.N.T. Biopsy sampling, bacteriology, cytology, and applied with the TV system to make video recording, teaching and dynamic recording. The endoscope is attached with biopsy sampling device, which helps to discovery pathological change in early stage. It could do surgery to remove polypus. The endoscope is a nice instrument for research on diseases of nasal cavity and throat and for checking up after operation.
