Precision and Safety of the Pulsed Electron Avalanche Knife in Vitreoretinal Surgery

Jason M. Miller
2003 Archives of Ophthalmology  
The PEAK also damaged tissue up to 1.4 mm away by the creation of water flow that formed at the tip of convex probes during collapse of a cavitation bubble.  ...  We have developed a new surgical instrument, called the pulsed electron avalanche knife (PEAK; Carl Zeiss Meditec, Jena, Germany), for precise, "cold," and tractionless dissection of tissue in liquid media  ...  The typical range of voltages used by PEAK during retinal surgery is 2 to 5 kV. at which the electric field is no longer sufficient to induce permeability (E th ) can be estimated as follows: r = Ί U ×  ...

Effects of Surface Pretreatment on Deposition and Adhesion of Electrophoretic Paint on AZ31 Mg Alloy

Van Phuonga Nguyen, Sungmo Moon
2017 Journal of the Korean institute of surface engineering  
Excellent adhesion was observed on the E-paintings deposited onto knife-abraded and SiC-abraded AZ31 Mg alloy samples.  ...  In this work, electrophoretic paint (E-paint) was deposited on AZ31 Mg alloy after four different surface pretreatments: knife abrading, SiC paper abrading, deionized (DI) water immersion and NaOH immersion  ...  Thus, knife-abraded and SiC-abraded samples required higher quantity of electricity during the induction stage than that of NaOH-immersed samples, and much higher than DI water-immersed sample.  ...

Cell Fragmentation and Permeabilization by a 1 ns Pulse Driven Triple-Point Electrode

Enbo Yang, Joy Li, Michael Cho, Shu Xiao
2018 BioMed Research International  
Ultrashort electric pulses (ns-ps) are useful in gaining understanding as to how pulsed electric fields act upon biological cells, but the electric field intensity to induce biological responses is typically  ...  A high electric field (2 MV/cm) can be created when pulses are applied. However, such a high electric field was found to cause bubble emission and temperature rise in the water near the electrode.  ...  This work has shown the feasibility of generating bubbles by 1 ns pulses to induce cell fragmentation and cell detachment.  ...
