Definitions

  • the invention relates to a shock wave generator for a device for the contactless crushing of concrements in the body of a living being, which has a coil with spirally arranged turns and an opposite, a liquid-filled space, made of an electrically conductive material membrane, the coil can be connected to a high voltage supply.
  • shock wave generator with a membrane arranged parallel to the coil is described in DE-OS 33 12 014.
  • the shock waves are generated by connecting the coil to the high-voltage supply, which converts one to several kV, e.g. 20 kV, charged capacitor contains.
  • the energy stored in the capacitor then suddenly discharges into the coil, with the result that the coil builds up a magnetic field extremely quickly.
  • a current is induced in the membrane which is opposite to the current flowing in the coil and consequently generates an opposing magnetic field, under the effect of which the membrane is suddenly moved away from the coil.
  • the so in the with liquid, e.g. Water, filled space shock wave generated by suitable measures on the concrements located in the body of the living being, e.g. Kidney stones, focuses and causes their destruction.
  • the invention has for its object to design a generic shock wave generator so that its membrane has a long service life without being associated with a significant reduction in the efficiency of energy conversion.
  • this object is achieved in that in areas of large potential difference between the turns of the coil on the one hand and the membrane on the other hand there is an increased distance between the two areas which is smaller than areas of small potential difference.
  • the invention takes advantage of the fact that the high voltage drops across the coil and thus the potential difference between the individual turns of the coil and the membrane is different. Accordingly, it is sufficient to ensure a long service life of the membrane if the distance between the turns of the coil and the membrane is increased compared to areas of low potential difference in those areas in which voltage flashovers are to be feared due to the large potential difference present.
  • a long service life of the membrane with a particularly low impact on the efficiency of the energy conversion can be achieved if, according to a variant of the invention, the outermost turn of the coil with the membrane is at the same potential and the inner turns of the coil are at a greater distance from the membrane.
  • the outermost turn of the coil with the membrane is at the same potential and the inner turns of the coil are at a greater distance from the membrane.
  • a further reduction in the effect of the measure according to the invention on the efficiency of the energy conversion is achieved according to one embodiment of the invention in that the increased distance between the turns of the coil and the membrane in areas with a large potential difference continuously decreases towards areas with a small potential difference.
  • This measure ensures that in areas of large potential difference between the individual turns of the coil and the membrane there is in fact only that distance which is to avoid voltage flashovers and thus to Ensuring adequate membrane life is required.
  • an embodiment of the invention provides that the membrane is at earth potential, which ensures that the liquid in the room which may be in contact with the living organism or the operating personnel Can come into contact, there is no high voltage.
  • a last variant of the invention provides that the turns of the coil are arranged on a support surface of an insulator, the support surface being designed according to the distance required between the turns and the membrane. This ensures safe compliance with this distance.
  • the shock wave generator has a housing 1 which contains a space 3 filled with a liquid and closed off by a membrane 2. Opposite the membrane 2 formed from an electrically conductive material, a coil 4 with spirally arranged turns is provided, an insulating film 5 being arranged between the membrane 2 and the coil 4. The turns of the coil 4 are arranged on a support surface 6 of an insulator 7, which is accommodated in a cap 8. The membrane 2, the insulating film 5 and the cap 8 containing the insulator 7 with the coil 4 are fastened to the housing 1 by means of screws 9.
  • the space located between the insulating film 5 and the support surface 6 of the insulator 7 is one
  • electrically insulating cast resin not shown, is filled in.
  • the coil 4 can be connected via connections 10 and 11, which emerge through bores in the insulator 7 and the cap 8, by means of a suitable switching means 12 to a schematically illustrated high-voltage supply 13, which emits a current surge to the coil 4, thereby causing the membrane 2 is suddenly repelled by the coil 4, which leads to the formation of a shock wave in the liquid in the space 3.
  • potential differences occur between the membrane 2 and the individual turns of the coil 4.
  • the outermost turn 14 of the coil 4 with the membrane 2 is at the same potential, namely earth potential 15, so that between the inner turns 16 to 21 of the coil 4 and the membrane 2 there is a high potential difference.
  • the turns 16 to 21 are consequently arranged at a greater distance from the membrane 2 than the outer turns of the coil 4, which have a smaller potential difference from the membrane 2.
  • the distance between the windings 16 to 21 from the membrane 2 also decreases in the sense of the decrease in the potential difference, namely continuously, the contact surface 6 of the insulator 7 being shaped in accordance with the distance required between the windings 16 to 21 and the membrane 2.
  • shock wave generators with a flat membrane 2 is shown. It is also possible to design shock wave generators with a different, for example spherically shaped membrane according to the invention.
