Objective

2

To explore the application of three testing methods

namely visual inspection method

insulation tester and insulation tester combined with magnification with light source

in the testing of insulation performance of electrosurgical instruments.

Methods

2

Two hundred and ninety electrosurgical instruments were selected from October 2020 to March 2021

and their insulation properties were examined by visual inspection

insulation detector and insulation detector combined with light source magnifier.

Results

2

The three methods of visual inspection

the insulation detector and the insulation detector combined with a light source magnifying glass detected 3.45%

11.03% and 15.52% of insulation breakage

respectively

p

<

0.05

with statistically significant differences. The differences were statistically significant.

Conclusion

2

The visual inspection method is time consuming

laborious

has a low detection rate and is prone to leakage

and is not recommended for routine use. The Insulation Tester is an efficient

accurate

time- and labour-saving method for detecting insulation faults and can be used for daily testing of the insulation properties of electrosurgical instruments. The Insulation Tester combined with a lighted magnifying glass provides a more comprehensive and accurate detection of existing and potential faults in the insulation and can be used for regular testing of the insulation of electrosurgical instruments as it is relatively time consuming and labour intensive. Both of the latter are effective in preventing the risk of leakage from electrosurgical instruments and are of great importance for surgical safety.
