Definitions

  • the present invention relates to a device for transmitting ultrasound according to the preamble of claim 1 (cf. WO 2007/101362 A2 ).
  • Such devices are used, among other things, for amplitude transformation or for amplitude amplification of the ultrasonic vibrations transmitted from a converter to a sonotrode.
  • DE 10 2016 116 430 A1 discloses a sonotrode with two sonotrode end faces and a peripheral lateral surface, which has an elongate core element and a wing element.
  • the EP 1 229 515 A2 discloses a curved ultrasonic waveguide for use in a surgical instrument.
  • the device has a curved oscillating body with a coupling surface provided at one end for coupling a converter, the oscillating body being curved in particular in the shape of a U, an S or a J is trained. Furthermore, the oscillating body has at least one constriction running over the entire circumference of the oscillating body between the coupling surface and the end opposite to this. With such a trained oscillating body very good results can be achieved despite the curved training due to the running over the entire circumference of the oscillating body retraction, with due to the curved design of the oscillating body assembly of the entire arrangement can be carried out without any problems, even in the case of very complex or cramped space conditions.
  • the oscillating body On both sides of the at least one constriction, the oscillating body has partial sections in the shape of a quarter of a circle, so that a deflection of 90° in the same plane or in different planes is achieved with each partial section.
  • quadrant-shaped partial sections between which there is a recess, has achieved good results in tests.
  • the oscillating body can have a substantially constant cross-sectional shape apart from the constriction. This means that the oscillating body is designed uniformly over its essential course and, apart from the recess or a base for coupling surfaces, has the same cross-sectional shape.
  • the constriction can be curved in cross section, for example as a circumferential annular groove.
  • a further coupling surface for a sonotrode can be provided at the end opposite the coupling surface.
  • the oscillating body can be equipped with different sonotrodes and converters thanks to a modular design.
  • a sonotrode can be formed in one piece on the end opposite the coupling surface. Complicated installation situations can be accomplished with such a very compact component, and losses can be minimized due to an uninterrupted material transition between the sonotrode and the oscillating body.
  • the oscillating body can have a rectangular or a square cross section. In contrast to other or asymmetrical cross-sections, a particularly uniform vibration behavior can be achieved in this way.
  • the oscillating body is designed in multiple parts.
  • the oscillating body can be curved in any plane, which can be advantageous in complex installation situations. However, it can also be advantageous to design the oscillating body to be curved only within one plane. A further advantageous embodiment can be formed in that the oscillating body is curved in two planes running at right angles to one another.
  • FIG. 1 shows a first device for transmitting ultrasound to a sonotrode, which shows a curved oscillating body 10 with a coupling surface 14 configured at one end 12 for coupling a converter.
  • the oscillating body 10 is in the form of an (inverted) U and has a further coupling surface 18 for a sonotrode on the end 16 opposite the coupling surface 14 .
  • Both coupling surfaces 14 and 18 are designed in the shape of a circular ring and are formed on the oscillating body 10 via a base 20 or 22, respectively.
  • the oscillating body 10 apart from the recess 24 and the bases 20 and 22 with the coupling surfaces 14 and 18 formed thereon has a constant, approximately rectangular cross-sectional shape.
  • the Concavity 24 has a concavely curved cross section in the exemplary embodiment shown, so that a total of four grooves running at right angles to one another are formed on the outer circumference of vibrating body 10 by concavity 24 .
  • the vibrating body 10 of 1 which is made in one piece from metal, has a constant radius of curvature on both sides of the recess 24, resulting in the overall shape of a U.
  • the vibrating body 30 of 2 differs from the vibrating body 10 of 1 solely in that the two curved sections A and B on either side of the recess 24 are oriented in such a way that the vibrating body has the shape of an S (or approximately a Z).
  • the oscillating body has a constant radius of curvature on both sides of the constriction 24 .
  • the curvature of the oscillating body has an inflection point in its center, ie in the area of the constriction 24 .
  • the oscillating body 40 shown corresponds in its basic structure to the oscillating body 10 of FIG 1 .
  • the oscillating body 40 has no base and no further coupling surface at its end 16 opposite the coupling surface 14 .
  • a sonotrode S is formed in one piece at the end 16 , a further constriction 44 being provided between the sonotrode S and the section A of the oscillating body 40 , which is designed in the same way as the constriction 24 .
  • FIG. 4 shows another embodiment of an oscillating body 50, which in its basic structure the oscillating body 30 of 2 corresponds, however, the two sections A and B, which are each formed in the shape of a quarter circle, compared to the embodiment of 2 are twisted by 90°.
  • the oscillating body 50 is in two planes at right angles to one another curved, ie the two coupling surfaces 14 and 18 do not run in one and the same plane ( 1 ) and also not within two parallel planes ( 2 ). Rather, in the case of the oscillating body 50, the two coupling surfaces 14 and 18 run in two planes running at right angles to one another.
  • the recovery 24 is in the embodiment of 4 also curved in cross section.
