The customer alleged: "1.We are doing quality review of the patient issue with the leep machine.When the probe was placed into the vaginal canal, prior to touching any tissue, it arced and caused a burn to the patients uterus.When investigating i found the grounding pad used mfr22-esrec was expired.Quality is asking for confirmation from the company that expired pads could cause this type of issue.Otherwise, i may have to send the machine in to be checked (again - it's been in twice and found to be fine).".
