Definitions

  • the invention relates to a shock wave source for the treatment of concretions in the body of a patient with a liquid-filled shock wave tube, one end of which is closed by a flexible sack that can be pressed against the patient by means of the liquid pressure and the other end of which is a membrane made of electrically conductive material which, separated by an insulating material layer, opposite a surface coil which is connected to a supply unit for generating high-voltage pulses.
  • a shock wave source of this type can be used to generate focused shock waves which are directed to the concrement to be broken, e.g. a kidney stone, can be straightened and smashed it so far that it comes off naturally.
  • the shock wave is generated by the fact that a high-voltage capacitor is connected across the surface coil, e.g. may have a spiral winding, is discharged, thereby repelling the membrane and directing a shock wave over the liquid and an acoustic lens in the shock wave tube at the stone to be broken.
  • a shock wave source of this type is known in which both a coil end and the membrane are at ground potential. This means that when a high voltage of, for example, 20 kV is applied to the surface coil to generate a shock wave, the entire high voltage is also between a point of the surface coil and the membrane. The layer of insulating material between the surface coil and the membrane must therefore be dimensioned for the entire high voltage be. Nevertheless, it is not always possible to avoid rollovers. In the event of a rollover, the membrane is destroyed.
  • the invention has for its object to design a shock wave source of the type mentioned so that the risk of voltage flashovers between the surface coil and the membrane is reduced compared to the prior art.
  • the membrane is electrically isolated from both ends of the surface coil.
  • the membrane and one coil end are not earthed, so that the entire high voltage lies between the membrane and the coil. Because of the electrical insulation of the membrane from both coil ends, the insulating distance for the entire high voltage is twice the distance between the coil and the membrane, so that the risk of breakdown is extremely low.
  • a shock wave tube 1 is shown, which is closed on its application side by an elastic bag 2 that can be placed on a patient and on its opposite side by a membrane 3.
  • the space between components 1, 2, 3 is filled with water as the coupling medium.
  • An acoustic lens 4 for focusing the generated shock waves is arranged in it.
  • the shock wave is generated with the aid of a surface coil 6 opposite the membrane, which is spirally wound and separated from the membrane 3 by an insulating layer 7.
  • One connection of the surface coil 6 is grounded and the second connection can be connected to a high-voltage generator 8 for generating shock waves.
  • the high-voltage pulse generated in this way due to the eddy currents generated in the membrane 3 from metallic material, causes the membrane 3 to be repelled, as a result of which a shock wave is caused by the water in the shock-wave tube 1 up to the stone in the patient reproduces.
  • the membrane 3 is electrically insulated from both ends 6a, 6b of the surface coil 6.
  • the entire insulating distance which must withstand the maximum high voltage, is therefore equal to the double thickness of the insulating layer 7.
  • the risk of flashovers between a point of the surface coil 6 and the membrane 3 is accordingly extremely low. If a rollover took place, it would generally run between the coil end 6a, the membrane 3 and the coil end 6b. It follows from this that the entire insulating distance is equal to twice the distance between the surface coil 6 and the membrane 3, so that sufficient insulation is ensured even with a thin layer of insulating material 7.
