To optimize the chemical composition of the crystals of nanostructured partially stabilized zirconium dioxide for fabricating cutting parts of an electrosurgical tool, the structural and strength properties of these crystals were investigated in dependence on the stabilizing impurity (Y2O 3) content and the effect of additional dopants on the critical properties of the material was studied. It was established that in all the investigated crystals without additional doping, regardless of the stabilizing impurity content, there are two phases of zirconium dioxide tetragonal modification with different tetragonality factors, c/a = 1.006-1.007 and 1.014-1.015, the first being nontransformable and the second being transformable to a monoclinic phase. All the synthesized crystals are characterized by a pronounced twin domain structure, which forms upon cooling the single crystal during the transition of the cubic structure to the tetragonal one. It was established that the Y2O3 concentration in the range from 2.5 to 3.0 mol % is optimal for ensuring high values of the strength characteristics and fracture toughness of the material. Doping of the crystals with the rare-earth elements notice-ably affects their strength characteristics. One of the most promising materials for fabricating cutting blades of the electrosurgical tool is the crystals of partially stabilized zirconium dioxide doped with Ce2O3+Nd2O3, which are characterized by high fracture toughness and enhanced bending strength. © 2013 Pleiades Publishing, Ltd.

Materials for construction of the cutting parts of surgical tools are considered in this work. The choice of nano-structured crystals of partially stabilized zirconium dioxide (PSZD) as the optimum material for electrosurgical cutting tools is based on criteria of operational stability and functional efficiency. Models of innovative tools are presented including bipolar electrosurgical scissors, bipolar scalpels, and dissector clamps for electro ligaturing. The tools are intended for use with Plasmotom high-frequency electrosurgical devices that generate low-temperature plasma. © 2010 Springer Science+Business Media, Inc.
