1. Light leakage end of the fiberscope endoscope body

(1) The leak point of the new fiberscope

1 brand new fiber optic endoscope light leakage point ≤ 5 is a normal phenomenon, will not be replaced (regulation: the fiber optic endoscope leakage point sold in 5 or less is normal, does not affect the use, can not be replaced, returned) ;

2 From the date of receipt, within three working days, the fiberoptic endoscope received and found to have a light leakage point and >5. If the customer requests to return, the customer needs to seal the photo on the spot and contact the agent or region in the area. The manager will handle it; if it is not sealed, or if it is used without authorization, it will not be returned.

3 Fiber optic endoscopes with >5 light leakage points discovered after more than 3 working days after receiving the goods will not be replaced.

(2) Light leakage spots appear during use

1 There is a light leakage point within 0-60mm from the end of the objective lens (Fig. 1). Most of the cases are caused by the use of the process, such as violent operation and passive bending.

Figure 1: Fiber optic endoscope light leakage point >10, concentrated in the 0-39mm from the end of the objective lens

2 The light leakage point appears at the position corresponding to the connection between the conduit and the displacement compensator, mostly due to the unsatisfactory assembly of the conduit and the displacement compensator, and the connection is not strong. The light leakage point caused by this condition is concentrated at about 920 mm from the end of the fiberscope endoscope when using the YC-IU-C catheter; when it is used, the YC-IU-B catheter is concentrated at about 770 mm from the end of the fiberscope endoscope; The YC-FR-A catheter is concentrated around 840 mm from the end of the fiberscope endoscope.

3 When the light leakage point appears at the position corresponding to the front end of the catheter (Fig. 2), most of them are limited by the expansion catheter of the ureter during the operation, and the holding method is incorrect, resulting in severe distortion and bending. Or violent operation, when using the YC-IU-C catheter, it is concentrated about 700mm from the end of the fiberscope endoscope; when using the YC-IU-B catheter, it is concentrated around 770mm from the fiberscope endoscope; using YC The -FR-A catheter is concentrated around 640 mm from the end of the fiberscope endoscope (Figure 4).

Figure 4: The marked marked light leakage point is 633mm from the end of the objective lens.

4 When the light leakage point appears in the position corresponding to the fixed position of the displacement compensator crystal head, most of them are caused by excessive tightening during the fixing process, and the fiber endoscope suffers from excessive pressure. When using the YC-IU-C catheter, the concentration is concentrated. The end of the fiberscope endoscope is about 1040mm (Fig. 5); when using the YC-IU-B catheter, it is concentrated around 890mm from the end of the fiberscope endoscope; when using the YC-FR-A catheter, it is concentrated in the fiberscope. The end of the objective lens is about 960mm.

   Figure 5: The black outer protective layer has an indentation. After inspection, it is broken at 1040mm from the end of the objective lens.

5 When the light leakage point is located at the position corresponding to the rear end of the displacement compensator, most of them are due to the improper holding method of the handle or the position where the camera is placed, resulting in the fiber endoscope being pulled, resulting in bending; The endoscope has a black outer protective layer. If a light leakage point is found, the damage is serious.

6 The light leakage point appears at the end of the eyepiece. Most of them are not noticed when the camera is placed on the patient's abdomen. As a result, the fiberoptic endoscope is limited by the camera and is pulled, which is caused by severe distortion and bending.

7 There are light leakage spots in other parts, most of which are caused during cleaning, disinfection and transportation; or they are normal wear and tear.

2. Fiberscope imaging and lighting problems

1 After the host is connected, the field of view is white and there is no image, which is caused by the breaking of the imaging fiber.

2 After the host is connected, the field of view is black but there is imaging, which is caused by the break of the illumination fiber.

3 After the host is connected, the field of view is black and there is no image, which is caused by the breakage of the imaging illumination fiber.

4 imaging has a grid, that is, the moiré is serious, which is caused by improper resolution of the resolution.

5 There are one or two strong reflective points in the field of view during the operation. For the front end of the fiber endoscope, there is a foreign object, which is caused by reflection. The front end of the fiber endoscope can be gently wiped with a cotton swab.

6 During the operation, whitening, yellowing and redness appear, which is caused by the front end of the lens body being too close to the mucous membrane, stones and blood clots.

3. Send back to the company for repair or inspection of fiber optic endoscopes

(1) Simply return the fiber optic endoscope and 2 protective sleeves (without adapters).

(2) Packaging requirements

1 The fiber optic endoscope is placed separately. If it is fixed on the white disinfection disc, the edge area is fixed with tape.

2 If the displacement compensator is sent back if necessary, the fiber endoscope must be placed separately from the displacement compensator and the protective sleeve. Avoid fiber optic endoscopes being stressed and subject to collisions.

3 If the fiber optic endoscope sent back is placed in the disinfection box, add foam or foam around the disinfection box, and then add the paper box to fix it before wrapping it.

(3) The following is a non-compliant placement

4. Catheter FAQ

1. Packaging problem: the lens body is worn out and the package is damaged.

2. Luer joint fracture

3. The turning mechanism fails

4. When assembling, the fiberoptic endoscope cannot reach the front end of the catheter

5. 钬Laser fiber wears out or has no resistance to wear out

6. Water leakage: joint parts, handles

5. After the sale of the catheter considerations

1. Inspect the goods in time after receiving the goods, and complete the inspection within three working days after receiving the goods.

2. If the problem is found, it will not be unpacked.

3. Find the problem and take photos at the first time. The photos mainly include the site and the phenomenon; the number and lot number of the catheter.

6. Customer complaints for returning catheters

1. Before returning the catheter, you should contact the after-sales department and the after-sales department will agree to return it.

2. The outer packaging of the catheter should not be changed. The catheter is placed vertically and firmly in the package to avoid damage and deformation; it is convenient for the company to detect and judge more accurately.

7. Displacement compensator FAQ

1. Displacement compensator crystal joint break

2. Displacement compensator crystal joint can not effectively fix fiber endoscope

3. Displacement compensator activity
