Insulation Testing

Insulation testing on bipolar forceps by Sutter Medizintechnik GmbH

Bipolar forceps by Sutter Medizintechnik GmbH come with highly resistant and durable insulation coating. Constant use and reprocessing may, however, nevertheless lead to damage of the coating.

To ensure the electrical safety of your bipolar forceps, proceed as follows:

Examine the forceps with the help of a magnifying glass visually. Particularly check for deep dents, scratches, cracks, corrosion, and other mechanical damage.

In case you discover significant damage to the insulation, in particular such damage that reaches the uninsulated metal surface of the instrument, the insulation will be impaired and not functioning properly any longer. In this case, have the instrument replaced by a new one. Please note: The guide pin (see illustration below) of bipolar forceps by Sutter Medizintechnik GmbH by design is uninsulated metal. It is not part of this investigation and the electrical tests described below.

If unsure or if this is a standard procedure in your healthcare facility, use a high-voltage tester for electrical testing. There are several suppliers of such devices on the market. Since their function and set-ups are different, applicable voltages may vary. Therefore, we recommend testing with the following products exclusively:

  • High-voltage testing device “Elabo 90-1D“
  • Test cable with alligator clip and sponge, soaked in NaCl 0,9% (squeeze the spongeafter soaking. It must be moist, not dripping!)
  • Test cable with matching connector for attaching to the forceps or with alligator clip

For manual use, a safety-circuit limited device such as the Elabo 90-1D mentioned-above is mandatory. Prior to use, read the instructions for use of the high-voltage tester and the general national standards applicable in your country carefully! The device must only be set up by a specialist in electro-technology while testing may likewise only be performed by trained and qualified staff!

For testing, adjust the high-voltage tester to the following parameters:

  • TEST mode
  • Voltage: 0.66 kV
  • I max: 1.50 mA
