Definitions

  • the invention relates to a shock wave generator for the contactless smashing of concrements located in the body of a living being with a shock wave source in a housing and with a sack covering the outlet opening for the shock waves, which limits the coupling space filled with a coupling fluid.
  • shock wave generator of this type is described in DE-A-33 28 051.
  • the shock wave source is arranged stationary with respect to the housing.
  • the entire shock wave generator must therefore be adjusted to adjust the focus.
  • the shock wave generator e.g. Acoustically coupled via the sack and a gel disc to the surface of the patient and if a focus shift is then required, a decoupling and a new acoustic coupling must take place. This puts a strain on the examination staff.
  • EP-A-0 327 917 which is older but has a higher priority, describes a shock wave generator, the shock wave source of which, in its entirety, is mounted such that it can be adjusted in a straight line relative to the housing along the central axis of the shock wave generator.
  • DE-A-2 732 254 describes a device for installing the transducer of an echo sounder in the boat wall of a boat, which has a fastening body designed as an essentially closed housing, on which the transducer is mounted so that it can be aligned and locked. After the transducer has been installed in the boat wall, the transducer is aligned and once in the required manner then determined that it maintains its orientation as long as it is installed in the respective boat.
  • the invention has for its object to design a shock wave generator of the type mentioned in such a way that a focus shift within predetermined limits is possible even when the shock wave generator is already acoustically coupled to the surface of the patient.
  • the shock wave source is mounted such that it can be adjusted in two dimensions in such a way that the longitudinal axis of the shock wave source can be pivoted independently of the housing and the bag.
  • the shock wave generator according to the invention it is accordingly possible, by adjusting the shock wave source in its housing with a housing that is stationary with respect to the patient, to carry out a focus shift and thus an optimal focus adjustment.
  • the shock wave generator can be coupled to the patient by adjusting the housing with the bag relative to the shock wave source. With this adjustment the focus position does not change.
  • An expedient embodiment of the invention consists in that the shock wave source is connected to a centrally arranged location system and is adjustably mounted together with it.
  • the adjustment of the location system with coupled shock wave generator enables fine or localization. If this location shows that the focus does not have the desired position in the calculus to be crushed, the focus system can automatically adjust the focus by adjusting the shock wave source on the basis of the output signals.
  • a housing 1 in which a shock wave source 2 is arranged.
  • the shock wave source 2 has a piezo crystal 3, which directs shock waves via an acoustic lens 4 to a focus 5.
  • An acoustic sump 6 is arranged behind the piezo crystal 3 and absorbs the shock waves emitted on the rear.
  • the coupling space 7 in the housing 1 is filled with a coupling liquid, e.g. Water, filled.
  • a coupling liquid e.g. Water
  • the end of the housing 1 that emits the shock waves is closed by a flexible sack 8, which is used for acoustic coupling to the patient. He lies on the surface of the body.
  • the shock wave generator shown has an ultrasound location system 9 which is located centrally in the shock wave source 2.
  • the ultrasound locating system 9 is rotatably mounted for locating the concrement to be broken. It is connected to the shock wave source 2 with a tube 10, which with With the help of a ball joint 11 is pivotally mounted in two dimensions, in two coordinates that define a plane perpendicular to the plane of the drawing.
  • the tube 10 is adjusted with the aid of electric motors, one of which is designated 12, via a gear 13.
  • the housing 1 is connected to a holder 14 by means of guides 15, 16.
  • the guide 15 has a motor-rotatable threaded spindle, which makes it possible to connect the housing 1 with the shock wave source 2 relative to the holder 14 in the third dimension, i.e. to adjust in the direction of axis 17.
  • the housing 1 For shock wave treatment, the housing 1 is moved so far to the body surface of the patient with the aid of the guides 15, 16 that the sack 8 lies against this body surface. A reflection-free sound transition is possible by inserting a gel disc between the sack 8 and the body surface.
  • the setting of the shock wave source 4 with the ultrasound location system 9 can be carried out independently of this adjustment process by pivoting the tube 10. The components 4, 9 are adjusted in the housing 1.
  • shock wave generator coupled to the patient, to shift the focus 5 within predetermined limits, that is to say to adjust it precisely to the concretion.
  • the position of the calculus can be located and the focus can then be adjusted accordingly.
  • This focus adjustment can also take place automatically via the motors 13, etc. driving the tube 10.
  • a suitable pivoting of the tube 10 with the shock wave source 2 enables the focus 5 to move on a predetermined path.
  • the motors 13, etc. are controlled accordingly.
  • a focus area of a predetermined extent can be scanned and an artificial focus magnification can be achieved in this way.
  • the shock wave source 2 is a piezoelectric shock wave source in the illustrated embodiment. Instead of such a piezoelectric shock wave source, another shock wave source, e.g. an electrodynamic shock wave source are used, in which the shock waves are generated with the aid of a membrane, behind which there is a flat coil, to which high-voltage pulses are supplied.
  • the shock wave source 2 is arranged in its holder 18 with the aid of a screw connection 19 so that the desired shock wave source can be used.
