How to Purchase an Electrosurgical Unit

Step-by-Step Guide

1. 1

   Step 1: Determine what the electro-surgical unit is being used for.

   There are numerous designs of electro-surgical units, and facilities should base their comparisons among devices according to characteristics, usefulness of features, safety, and reliability
   - all of these affect clinical performance. , Their typical frequency range is from
   0.3 to 1 MHz.
   
   They should also include the following:
   Isolated monopolar output.
   
   Hand switch.
   
   Footswitch.
   
   Bipolar output. , For monopolar cutting output power should not exceed 300 W, and the open circuit voltage should not exceed 2,000 peak-to-peak volts.
   
   For coagulation cutting, the output and open circuit voltage should not exceed 120 W and 6,000 peak-to peak volts, respectively.
   
   Bipolar mode should use no more than 50 W and 300 peak-to-peak volts. , Independent output visual and audible activation indicators.
   
   Alarm capable of volumes higher than 45 dB at one meter.
   
   Power-setting display.
   
   Convection or fan cooling system. , The device should include an alarm capable of volumes higher than 45 dB at one meter.,

   Step 2: Check to see if the unit comes with a solid-state generator.

3. 3

   Step 3: Ensure that the output power for your procedure is not too high.

4. 4

   Step 4: Make certain that all units should include the following

5. 5

   Step 5: regardless of the intended procedure: Return electrode contact quality monitor.

6. 6

   Step 6: Ensure that argon-enhanced units have a flow range of 0 to 10 L/min

7. 7

   Step 7: a tank capacity of more than 1

8. 8

   Step 8: 200 L (42 ft3)

9. 9

   Step 9: and a low-pressure alarm.

10. 10

    Step 10: Consider whether a compatible argon module is needed or an entirely new unit with an integral argon device.
