ELECTROMAGNETIC GENERATOR OF FOCUSED IMPACT WAVES Russian patent published in 1999 - IPC

FIELD: medicine; biology. SUBSTANCE: generator refers to equipment of conversion of electric power to power of sound pulses or impact waves. Generator has inductor in metal casing, capacitive storage, connected to inductor coil through controlled discharger, and reflector. Multilayer inductor coil is shaped as spiral winding of thin metal band with insulation layer. Coil turns are provided with parallel strip leads outcoming from coil end faces and connected to capacitive storage through auxiliary controlled dischargers. This construction makes it possible to crush biliary and renal calculus more effectively. Inductor coil may be manufactured in form of circular cylinders or circular truncated cone. Metal casing may be made as external short-circuited turn of inductor coil. In this case, inductor coil is connected in transformer circuit. EFFECT: enlarged functional capabilities. 5 cl, 7 dwg
