Abstract
The invention relates to tissue scissors () with improved stability and improved handling that have two structurally and electrically different branches (). While the sliding surface () of the first branch () has a metal-ceramic hard material layer (), such as, for example, titanium nitride, the second sliding surface () of the second branch () has an electrically non-conductive ceramic layer (). The material mating produces great mechanical resistance to abrasion in the bearing () and on the cutting edges (). At least one of the branches, in particular branch (), can have a cermet body () to improve the cooling of the cutting edge (()) and/or keep it sharp, to prevent heating of the branches () during coagulation and sticking of the tissue.
