00:00:00.400 --> 00:00:02.680
Dear ladies and gentlemen, I would like to

2
00:00:02.680 --> 00:00:07.200
welcome you today within the framework of our seminar series Sterile Goods Processing with the

3
00:00:07.200 --> 00:00:12.080
topic Surface Changes - Recognition, Causes and Prevention.

4
00:00:12.980 --> 00:00:16.260
First, a brief review of the previous seminar blocks

5
00:00:16.260 --> 00:00:20.780
1 to 3 with the topics Process Water Treatment, Equipment Technology

6
00:00:20.780 --> 00:00:24.200
and Instrument Science, in order to pick up the common thread

7
00:00:24.200 --> 00:00:28.320
that runs through the seminar series Sterile Goods Processing again

8
00:00:28.320 --> 00:00:32.660
and further complete it with the topics Surface Changes, Causes and Prevention.

9
00:00:32.660 --> 00:00:34.360

10
00:00:34.920 --> 00:00:38.740
The seminar document folder, which is handed to each participant during the

11
00:00:38.740 --> 00:00:42.340
seminar, is an important support to

12
00:00:42.340 --> 00:00:45.940
actively refine the seminar content and for

13
00:00:45.940 --> 00:00:49.940
further use in the professional field of activity as a so-called

14
00:00:49.940 --> 00:00:52.420
action matrix can be used.

15
00:00:53.760 --> 00:00:58.420
The different manifestations of surface changes as well as

16
00:00:58.420 --> 00:01:01.960
their causes and preventions are explained by the instructor

17
00:01:01.960 --> 00:01:05.920
and the connections are brought closer to the seminar participants using practical

18
00:01:05.920 --> 00:01:07.140
examples.

19
00:01:07.140 --> 00:01:12.260
The participant can observe silicate deposits on an osteotome more closely

20
00:01:12.260 --> 00:01:15.460
using a magnifying lamp and thus recognize the risks

21
00:01:15.460 --> 00:01:20.160
of these surface changes over the duration of instrument use at

22
00:01:20.160 --> 00:01:24.740
the silicate deposit boundaries with the beginning of pitting corrosion.

23
00:01:25.940 --> 00:01:29.660
With the hand microscope, pitting corrosion on a flat chisel

24
00:01:29.660 --> 00:01:30.600
is examined more closely.

25
00:01:30.600 --> 00:01:36.020
Through the complicated geometry of the

26
00:01:36.020 --> 00:01:39.900
hole structure, the seminar participant can recognize and evaluate the difficulty

27
00:01:39.900 --> 00:01:43.520
for hygienically perfect sterile goods processing of the instrument.

28
00:01:44.560 --> 00:01:47.960
Through a multiple-choice questionnaire, participants have

29
00:01:47.960 --> 00:01:50.960
the opportunity to check the knowledge acquired up to this point

30
00:01:50.960 --> 00:01:54.480
and consolidate it with the support of

31
00:01:54.480 --> 00:01:56.020
the instructor.

32
00:01:56.020 --> 00:02:00.580
In difficult assessment cases, the hand microscope tool is used for

33
00:02:00.580 --> 00:02:04.460
error detection to obtain a valid statement and the

34
00:02:04.460 --> 00:02:08.160
necessary certainty about the functional capability of the instrument to be analyzed.

35
00:02:08.160 --> 00:02:08.800

36
00:02:09.919 --> 00:02:14.060
Corrosion and other damage to rongeur forceps are

37
00:02:14.060 --> 00:02:16.520
recognized by the participant with a magnifying lamp and

38
00:02:16.520 --> 00:02:17.300
examined more closely.

39
00:02:18.020 --> 00:02:21.460
The functional test of a sharp spoon using a PE

40
00:02:21.460 --> 00:02:23.720
test rod is performed here.

41
00:02:23.720 --> 00:02:27.940
A functional deficiency, the lack of sharpness, is determined at this

42
00:02:27.940 --> 00:02:29.760
point as a result.

43
00:02:30.700 --> 00:02:34.140
With the support of the instructor, the questions

44
00:02:34.140 --> 00:02:38.460
for the practical part multiple-choice questionnaire can be

45
00:02:38.460 --> 00:02:39.440
answered by the seminar participants.

46
00:02:40.920 --> 00:02:44.120
Surface changes and surface damage to surgical

47
00:02:44.120 --> 00:02:47.880
scissors are recognized by the seminar participant and can

48
00:02:47.880 --> 00:02:51.160
thus be correctly assigned and answered in the questionnaire.

49
00:02:51.160 --> 00:02:54.840
After completion of seminar block 4 with

50
00:02:54.840 --> 00:02:59.460
the topic Surface Changes, Causes and Prevention,

51
00:02:59.460 --> 00:03:03.860
seminar participants receive a certificate for successful participation.

52
00:03:04.820 --> 00:03:07.320
I would be pleased to welcome you as a participant in our

53
00:03:07.320 --> 00:03:11.780
seminar series Sterile Goods Processing with the topic Surface Changes,

54
00:03:12.300 --> 00:03:14.560
Causes and Prevention.
