Pentax ECY-1575K [69/80] 3 3 2 steam sterilization autoclaving

Before reprocessing and or immersion in any fluids pentax endoscopes should be tested for the loss of integrity in their watertight construction by using pentax brand leak testers for specific details on pentax recommended leak detection procedures please refer to the instructions supplied with pentax leak testers 12

Inspection of the insertion tube a check the entire surface of the insertion tube for abnormal conditions such as dents crush marks wrinkles bumps buckles excessive bending protrusions peeling of outer sheath cuts holes or other irregularities any crush or indentation of the flexible shaft of the endoscopes can cause damage to the internal mechanisms of the endoscopes b similarly check the condition of the umbilical cable for outward signs of damage such as buckling crush marks etc 12

Inspection of angulation controls slowly manipulate the angulation control lever to see that it functions smoothly be certain that a full and appropriate range of angulation is possible 18

Inspection of irrigation mechanism a prior to use the irrigation control valve of b163 should be inspected remove the valve from the control body and make sure that the rubber portion is not damaged or worn 19

E any accessory should be slowly inserted through the instrument channel inlet with the endoscope in a straight position there should be no resistance encountered if resistance is encountered do not attempt to introduce the accessory further the instrument channel may be damaged and the endoscope should not be used contact the pentax service department 23

3 preparation just before insertion of endoscope 25

Gently clean the objective lens and the light guides with a cotton tip applicator moistened with 70 90 medical grade ethyl or isopropyl alcohol a lens cleaner anti fogging agent may also be applied via gauze or other applicator 3 check the endoscopic image and confirm that it is of acceptable quality for clinical use refer also to the owner s manual supplied with the pentax video processor for inspection of the image quality 4 apply a medical grade water soluble lubricant to the insertion tube do not use petroleum based lubricants 25

If the endoscope has just recently been reprocessed has been prepared or stored properly and passed all pre procedure inspections the instrument should be ready to use if necessary the endoscope s insertion tube may be wiped down with a gauze dampened with 70 90 medical grade ethyl or isopropyl alcohol 25

1 pretreatment 27

2 insertion and withdrawal 27

Adjust the intensity of the video processor to obtain a brightness level suitable for observation 27

Begin flow of irrigant then insert the endoscope slowly under direct vision 27

Directions for use 27

The angulation control should be used as needed to position the endoscope angulation of the tip should be performed under direct vision in a gentle and deliberate manner should resistance be encountered never apply excessive force 27

The patient should be prepared in your normal endoscopy regimen 27

Image capture hard copy documentation video recording etc may be carried out as necessary 5 when attempting to withdraw the endoscope return the angulation control lever to its neutral position always withdraw the endoscope under direct visualization 28

3 biopsy 29

4 laser 30

Should the distal tip of the endoscope be moved closer than 20 mm from the irradiated tissue surface the aiming beam may create a smear in the image as shown below if this smear affect becomes too severe and distorts the visual field the intensity of the aiming light should be decreased 31

When activating the laser at high power about 100w for yag laser and 60w for diode laser and or if the endoscope tip comes to within 10 mm of the irradiated tissue flare may appear at the corners of the image as shown below 31

5 electrosurgery 32

The operator and assistant s should wear rubber gloves and face masks to avoid burns during use of electrosurgical devices 2 the electrosurgical accessories should be introduced through the endoscope in the same manner as described for biopsy forceps in section 3 3 32
