Progress in interventional medicine is associated with the development of more delicate and less invasive surgical procedures, which requires more precise and less traumatic, yet affordable, surgical instruments. Previously we reported on the development of the pulsed electron avalanche knife for dissection of soft tissue in liquid media using the 100 ns plasma-mediated electric discharges appl...

the electro discharge machining (edm), one of the methods used in the machining industry and a non-traditional manufacturing method, the electro erosion process does not depend on the hardness of material and offers a way to process materials of very complex geometry with very fine and high precision by using cheap electrode materials, which make it a preferred method. in this study, effect of ...

The surface average temperature and the electrode distribution are key parameters to predict erosion. Experimental research on arc erosion has been carried out in a model circuit breaker, which CO2 is filled chamber Cu-W used as contact material. temperatures of plug exposed electric with sinusoidal currents 5kA were determined by high-speed pyroscope. In order establish relationship between cu...

As common electric contact materials, copper-carbon electrode pairs are widely used in the field of such as high-speed railways, motor collector rings and grounding brushes. They play a key role energy transmission above-mentioned systems. Arc erosion has become issue threatening system safety. In this work, dedicated arc platform was built to study polarity effect pairs. It found that dynamics...

INTRODUCTION The Argus II retinal prosthesis is composed of an epiretinal electrode array positioned over the macula and connected to an extrascleral electronics case via a silicone cable, running through a sclerotomy. During implantation, the manufacturer recommends to cover the sclerotomy site with a patch of processed human pericardium to prevent postoperative hypotony and conjunctival erosi...
