Definitions
- the invention relates to a device for generating shock waves according to the preamble of claim 1.
- Shock waves are understood here as weaker acoustic pressure pulses, the intensity of which is sufficient to cause changes in the bodies of living beings, e.g. the movement of stones or the warming of the tissue.
- a lithotripter with an area source is known. This is either designed as a self-focusing spherical cap or flat. Imaging systems such as reflectors, lenses or electrical controls of the different zones of the shock wave source are then required for focusing.
- a lithotripter with two shock wave sources is known from DE-Gm 88 02 995 .
- shock waves are generated extracorporeally and passed through the skin to the stone, on the other hand, the shock waves are generated at the end of a light guide near the stone.
- EP 277 489 A describes a lithotripsy work station with two of them independent shock wave sources known to act on the stone from different directions. This device forms the preamble of claim 1.
- the object of the invention is to improve the fragmentation of human concrements, in particular gallstones.
- shock wave sources offer the advantages of both types, as long as both sources are operated independently of one another - freedom in the choice of energy or the focus size. If both sources are operated in combination, in particular controlled by a shock circuit with an adjustable time delay, there are further advantages:
- the variable temporal superimposition of shock waves of different properties can have special effects on that from the other source excited stone occur.
- a piezo system and an electromagnetic shock wave system are preferably used, both systems being self-focusing - for example arranged on a curved support - or even, the focusing then being carried out by means of aids such as lenses, reflectors or electronically by differently controlling the individual zones of the shock wave sources.
- the two sources mentioned can be synchronized well in time.
- the preferred coaxial arrangement leaves the effort involved in location and positioning unchanged compared to a simple source. It is also possible - but not shown - to arrange the sources side by side.
- the coaxial arrangement of an electromagnetic source (EMSE) on the inside and a piezoelectric one on the outside is favorable, since the larger area is then available to the source with the lower energy density.
- the electromagnetic source can be self-focusing or can be focused with a lens.
- the piezo elements are preferably arranged self-focusing on a spherical carrier.
- a defined time delay between the two shock wave sources can be set electrically for both sources when using a shock circuit or by mechanically adjusting the sources against each other over the then different transit times.
- a hit control can also be carried out with the combination system. Reflections of the shock wave pulse of one partial shock source on the stone are detected by the other partial shock source.
- FIG. 1 shows a shock wave source according to the invention, in which a piezoelectric shock wave source P and an electromagnetic shock wave source E are arranged coaxially on the carrier T.
- the electromagnetic shock wave source E essentially contains the coil S, a membrane in front of it and the lens L necessary for focusing. Both shock wave systems (E, P) emit waves that are focused on one point (focal point F).
- other components such as the water flow path, a coupling device or systems for locating the calculus and for positioning the shock wave source with respect to the calculus are not shown.
- the marginal rays of the shock wave fields are shown, which lead from the piezoelectric shock wave source P and from the electromagnetic shock wave source E to the focal point F.
- the acoustic waves generated by the electromagnetic shock wave source E reach the focal point F earlier than the waves emitted by the piezoelectric shock wave source.
- FIG. 2 shows another embodiment with the same components as FIG. 1.
- the electromagnetic shock wave source is arranged farther away from the focal point F, as a result of which the energy generated by the electromagnetic shock wave source E is generated when energy is applied simultaneously Waves arrive later at the focal point F than the waves generated by the piezoelectric shock wave source P.
- the time delay can therefore be set both by a time delay in the electrical activation of the two sources (E, P) are also shifted against each other by shifting the sources (E, P), which changes the runtime. 2, both the lens L and the coil S are shifted to the rear. Versions are possible - but not shown - in which only one of the two components is displaced, the other remains stationary relative to the other shock wave source.
- FIG 3 shows a further embodiment of a shock wave source according to the invention, in which a piezoelectric shock wave source P and an electromagnetic shock wave source E are arranged coaxially on the carrier T such that they radiate onto a common focal point F.
- the focusing takes place with both shock wave sources (E, P) by the curvature of the carrier T.
