Geneious prime database4/15/2023 ![]() The L-T needle is a geometrically modified version of an L-mode needle whose efficacy as a prototype ultrasonic bone biopsy device has been previously demonstrated by the authors. This work presents a longitudinal-torsional (L-T) composite mode ultrasonic needle device for deep bone penetration. The system fulfilled these promises for us. The manufacturer claims that bone can be cut precisely without damage to soft tissue and with little bleeding ( Handbook, Mectron S.r.l., Carasco, Italy, 2002). The tool was also used to cut the removed bone before replantation. When the bones were more than about 3 mm wide, the cutting was slow but precise and without laceration of the dura mater. ![]() The cutting speed was dependent on the thickness of the bone. ![]() Firstly, we cut the calvarium to remove parts for later reposition. We cut the calvarial bones in two stages. In craniofacial surgery, we used the system in fronto-orbital advancement operations in children. ![]() 1) consists of a piezoelectric handpiece and a foot switch that are connected to a main unit, which supplies power and has holders for the handpiece and irrigation fluids. These are created by the piezoelectric effect: certain ceramics and crystals deform when an electric current is passed across them, resulting in oscillations of ultrasonic frequency. Piezosurgery ® (Mectron, Carasco, Italy) is a recently developed system for cutting bone with microvibrations. ![]()
