Re: Residual heat of laparoscopic energy devices: How long must the surgeon wait to touch additional tissue?

摘要

Editorial Comments Clinically we know that laparoscopic surgeons routinely touch and dissect tissue with energy based cutting instruments without complication. I suspect we get away with this because the contact time at a specific point when bluntly pushing tissue with an ultrasonic shears or monopolar scissors is brief. Nevertheless, this article provides us with valuable knowledge. Ultrasonic energy instrumentation, ?whose advocates often claim it as the safest tool, actually has the greatest residual heat and can heat tissue more than 20C even 20 seconds after activation.
