ELECTROSURGICAL UNIT PSD-30
• Patients may feel a neuromuscular stimulus when discharge
occurs in the coagulation output mode or when there is a
spark discharge to the forceps or another metallic object.
The neuromuscular stimulus is caused by low-frequency
components generated by rectification during discharging.
To prevent this, minimize the discharge by selecting a lower
output setting or by activating output when the electrode is in
contact with the tissue to be cauterized.
1.
Confirm that the settings on the front panel are correct and also confirm that
the foot switch pedal is correct before activating the output.
2.
By pressing the CUT pedal, cut output will occur. By pressing the COAG
pedal, coagulation output will occur.
3.
Output will take place while the foot switch is pressed. During output, the
output indicator will light and the output sound will be heard. Output will stop
when the switch is released. However, if the AUTO STOP mode is selected,
coagulation output will stop automatically while the pedal is pressed (see
Figure 5.9).
Figure 5.9
• The output controlled by the first pedal pressed will be
activated. Furthermore, when both pedals are pressed
simultaneously no output power is resulted and the output
setting indicators will be displayed as shown Figure 5.10.
