## Abstract

An apparatus for transmitting ultrasound comprises a curved oscillating body having a coupling surface for coupling a converter, wherein the oscillating body is curved and has a recess.

## Claims

### Claim 1

An apparatus for transmitting ultrasound, the apparatus comprising a curved oscillating body having a coupling surface provided at one end for coupling a converter, and wherein the oscillating body has at least one recess between the coupling surface and the end opposite thereto, said recess extending annularly over the entire periphery of the oscillating body.

### Claim 2 (depends on 1)

The apparatus in accordance with claim 1, wherein the oscillating body is curved in the shape of one of a U, an S, and a J.

### Claim 3 (depends on 1)

The apparatus in accordance with claim 1, wherein the oscillating body has a substantially constant cross-sectional shape apart from the recess.

### Claim 4 (depends on 1)

The apparatus in accordance with claim 1, wherein the oscillating body has part sections of quadrant shape at both sides of the recess.

### Claim 5 (depends on 1)

The apparatus in accordance with claim 1, wherein the recess is curved in cross-section.

### Claim 6 (depends on 1)

The apparatus in accordance with claim 1, wherein a further coupling surface for a sonotrode is provided at the end disposed opposite the coupling surface.

### Claim 7 (depends on 1)

The apparatus in accordance with claim 1, wherein a sonotrode is molded in one piece to the end disposed opposite the coupling surface.

### Claim 8 (depends on 7)

The apparatus in accordance with claim 7, wherein a recess is provided between the sonotrode and the oscillating body.

### Claim 9 (depends on 1)

The apparatus in accordance with claim 1, wherein the oscillating body has one of a rectangular cross-section and a square cross-section.

### Claim 10 (depends on 1)

The apparatus in accordance with claim 1, wherein the oscillating body has a constant radius of curvature at both sides of the recess.

### Claim 11 (depends on 1)

The apparatus in accordance with claim 1, wherein the curvature of the oscillating body has at least one inflection point.

### Claim 12 (depends on 11)

The apparatus in accordance with claim 11, wherein the curvature of the oscillating body has exactly one inflection point.

### Claim 13 (depends on 1)

The apparatus in accordance with claim 1, wherein the oscillating body is formed in multiple parts.

### Claim 14 (depends on 1)

The apparatus in accordance with claim 1, wherein the oscillating body is only curved in one plane.

### Claim 15 (depends on 1)

The apparatus in accordance with claim 1, wherein the oscillating body is curved in two planes extending at right angles to one another.

### Claim 16 (depends on 9)

The apparatus in accordance with claim 9, wherein the recess forms four grooves at right angles to one another, with a separate one of the grooves being formed along each side of the one of a rectangular cross-section and a square cross-section of the oscillating body.
