MMPD 8K Electrosurgical Insulation Defect Detector

Electrosurgical test

McGan Technology’s MMPD-8K electrosurgical insulation defect detector is a battery operated unit that tests the integrity, such as pinholes, cracks or defects, of the insulation of electrosurgical instrument in order to prevent inadvertent tissue burns which may occur during electrosurgical instrument procedures. The integrity of the insulation of electrosurgical instruments can occur over time, through normal surgical use, through the accidental contact with a sharp instrument or the rubbing of the insulation to the point of abrading it. The insulation failure provides an alternate pathway for the current to leave the instrument’s electrode usually beyond the sight of the surgeon which will result in the unintended tissue burn. Using an electrosurgical test equipment maintenance program can greatly reduce the number of these inadvertent burns during electrosurgical procedures.
