Definitions

  • the invention relates to a device for the contactless smashing of concrements located in the body of a living being with a shock wave generator, which is aimed at a target area in the body and which has a coil lying in one surface, in front of which there is a radiating element, which has a space filled with a liquid completes and generates a shock wave when the coil is briefly switched on to a high voltage.
  • the coil can be designed as a flat coil and can lie at one end of a shock wave tube that is closed on all sides and filled with liquid.
  • a flexible sack can be provided at the other end of the shock wave tube with which the shock wave tube is applied to the surface of the grain to be treated.
  • an acoustic lens can be arranged in the shock wave tube, which can be adjusted to focus the shock wave Due to the constructive design of such a device, there is a relatively large overall length of about half a meter.
  • Ultrasonics, Volume 5, April 1967, pages 105-107 discloses a device for. non-contact crushing of concrements, which has a spherical calotte sounding device.
  • the invention has for its object to simplify a device of the type mentioned in that the acoustic lens for focusing is unnecessary.
  • the coil and the radiating member have the shape of a spherical cap.
  • the shock wave is concentrated on the center of the sphere, in which the concretion to be broken must be positioned.
  • the radiating element from which the shock wave emanates can form the part of the wall of a liquid-filled trough in which the body lies in order to break up the concrement.
  • a treatment tank 1 is shown, is inserted into the membrane 2 made of flexible material and a spherical cap 3 carries, which serves as a radiating g song for the shock waves.
  • the membrane 2 is fastened elastically in the treatment tub 1 with the aid of a screwing.
  • a coil 4 which like parts 2 and 3.
  • the connections 5, 6 to the coil 4 are accordingly provided in the middle and on the edge of the coil 4.
  • this body is positioned in the water-filled treatment trough 1 such that the concretion 7 lies in the center of the spherical cap defined by the coil 4 and the spherical cap 3, which may be rigid. Then a high voltage is generated via a capacitor-resistor circuit, the several kV, z. B. 20 kV. This increase is briefly applied to the coil 4, with at least a portion of the energy stored in the capacitor suddenly discharging into the coil 4. A magnetic field is built up very quickly, which in the z. B. made of copper spherical cap 3 induces a current which is opposite to the current in the coil 4 and generates an opposing magnetic field.
  • the spherical cap 3 Due to the force of the opposing field, the spherical cap 3 is knocked away from the coil 4, the membrane 2 yielding resiliently. This knocking away of the spherical cap 3 generates a shock wave which is concentrated in the center of the spherical cap 3 and thus in the concrement positioned there. As a result, the concretion 7 is smashed.
