5.3 Basic parameters of endoscope
5.3.1 Field of view and angle of view
5.3.1.1 Method-1
5.3.1.1.1 The measuring instrument consists of the following parts:
a) Optical bench or similar device, which can support the endoscope for
testing, it may adjust the optical axis of the endoscope to coincide with the
center of the measuring target. At the end surface of the endoscope’s
head, measure the field of view at a point along the perpendicular direction
50 mm from the center point of the measuring target of the concentric
circle where the angle is marked;
b) The target holder and the dial divided by “degrees” (see Figure 1);
c) Measuring target for the measurement of field of view and angle of view
(see Figure 2): circular, with a set of measurements in unit of “degree”,
measured at 50 mm. The ring of the measuring target may be calculated
according to the formula (2):
Where:
D - The diameter of the measuring ring corresponding to different angles
of view, in millimeters (mm);
β - Field of view, in degrees (°).
The measuring target is fixed on the instrument.
There shall be a main marking line every 10°, as well as the corresponding
degree indications.
A line shall be marked every 2° between each main marking line, 4
marking lines in total.
d) Lighting shall be measured by white-light-illuminated measuring target,
the minimum illuminance is not less than 500 lx, it may use an endoscope
or external light source.
5.3.1.1.2 The following test methods are only recommended:
Fix the endoscope and adjust the distance between the objective lens and the
object to be observed. When the distance is at two positions: 1 mm and 50 mm,
it may clearly observe a 1.2 mm width line through the endoscope’s eyepiece,
which shall comply with the requirements of clause 4.4.
5.4 Endoscope’s performance
5.4.1 Defect and light spot of field of view
Turn on the cold light source and adjust to the brightest state. Observe the
illuminated white paper through the endoscope, which shall meet the
requirements of 4.5.1 and 4.5.5.
5.4.2 Test of half-unshielded eyepiece cover
Test according to the method of 5.5 in GB 11244-2005, the results shall meet
the requirements of 4.5.2.
5.4.3 Test of fog layer
Insert the insertion part of the endoscope into water which has a temperature
of 20 °C or less. After 10 min, take it out. Then insert it into water which has a
temperature of 40 °C. Take it out and wipe it dry. Observe from the eyepiece, it
shall meet the requirements of 4.5.3.
5.4.4 Sealing test
Test according to the method in YY 0068-1992, the results shall meet the
requirements of 4.5.4.
5.4.5 Illuminance uniformity
Place the illuminometer probe at a distance of 50 mm in front of the endoscope.
According to the angle of view of the endoscope, adjust the illuminometer probe,
to make it perpendicular to the view direction of the endoscope.
At the point A (A is the center of the field of view at the object side) in Figure 4,
use the illuminometer to measure the illuminance at that point, which is the
illuminance value E0 of the center of the field of view.
The illuminance at the edge of the field of view is measured at points B1, B2, B3,
B4 in Figure 4. In Figure 4, it divides the field of view at the object side into four
quadrants, each quadrant contains one measurement point, namely B1, B2, B3,
B4 (the four points are 70% of the field of view at the object side). Use the
illuminometer to measure the illuminance at each point, which is the illuminance
value at the edge of the field of view and recorded as E1, E2, E3, E4, respectively.
The calculated values of E1/E0, E2/E0, E3/E0, E4/E0 shall all comply with the
350 mm.
The test of the thickness and mass of the plating shall be carried out in
accordance with the provisions of GB/T 6463-2005 and the corresponding
inspection methods, the results shall comply with the requirements of 4.12.
5.10 Evaluation of biocompatibility
Check the relevant evidence of biocompatibility, which shall meet the
requirements of 4.13. Otherwise the test is carried out as follows:
a) It is carried out according to the method as specified in GB/T 16886.5-
2003, the results shall meet the requirements of 4.13 a);
b) It is carried out according to the method as specified in GB/T 16886.10-
2005, the results shall meet the requirements of 4.13 b) and c).
5.11 Safety requirements for interconnection with medical electrical
equipment
It is carried out according to the method as specified in Appendix A (Normative),
the results shall comply with the requirements of 4.14.
5.12 Environmental test
Test according to the test sequence and test method in GB/T 14710-1993 as
well as the requirements of 4.15, the results shall comply with the requirements
of 4.15.
