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 with which the shock wave tube is placed on the surface of the body to be treated.
- an acoustic lens can be arranged in the shock wave tube, which lens can be adjusted to focus the shock wave. Due to the constructive design of such a device, a relatively large overall length of about half a meter is given.
- 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 membrane 2 is inserted, which is made of flexible material and carries a spherical cap 3, which serves as a radiation element for the shock waves.
- the membrane 2 is fastened elastically in the treatment tub 1 with the aid of a screw connection.
- a coil 4 which like the parts 2 and 3 has the shape of a spherical cap. It runs spirally from a point at the apex of the spherical cap to the edge of the spherical cap.
- 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 high voltage 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 calculus 7 is smashed.
