Abstract

A lithotripsy work station having a patient support table and an adjustable mounting arrangement for the shockwave generator which has a coupling chamber with a membrane for coupling the shockwave generator to the patient characterized by the mounting arrangement positioning the shockwave generator directly above the patient supporting table. The shockwave generator can be mounted by a holder which rotates around a vertical axis above the patient supporting table so that a longitudinal axis of the generator can be aligned to intersect with the vertical axis roughly through the center of the patient supporting table. The mounting means can also be a separate holder which is movable in a horizontal direction that is secured to a ceiling in the room or is on a unit movable on the floor. In each of the embodiments, the shockwave generator can be mounted by an adjustable mechanism that allows changing the angle between the vertical axis and the longitudinal axis of the generator.

Claims

1. In a lithotripsy work station comprising a patient supporting table and an adjustably mounted shockwave generator having means including a membrane adapted for contacting a patient, the improvements comprising means for adjustably mounting the shockwave generator above said patient supporting table, said means for adjustably mounting the shockwave generator including a holder rotatable around a vertical axis above said patient supporting table, said holder mounting the shockwave generator with a longitudinal axis of the generator forming an angle with the vertical axis and intersecting the vertical axis roughly at a point adjacent the patient supporting table.

2. In a lithotripsy work station according to claim 1, wherein said holder includes means for adjustably positioning the shockwave generator along the longitudinal axis.

3. In a lithotripsy work station according to claim 2, wherein the holder includes means for adjusting the shockwave generator along said vertical axis.

4. In a lithotripsy work station according to claim 1, wherein the holder includes means for adjusting the shockwave generator along said vertical axis.

5. In a lithotripsy work station according to claim 1, wherein a power supply unit for the shockwave generator is mounted in said holder.

6. In a lithotripsy work station according to claim 3, wherein said point is at the center of the patient supporting table.

7. In a lithotripsy work station having a patient supporting table, a single shockwave generator having a longitudinal axis and a coupling chamber with a membrane adapted for contacting a patient, and means for mounting the shockwave generator, the improvements comprising the means for mounting the shockwave generator positioning the shockwave generator above the patient supporting table for movement around a vertical axis with the longitudinal axis forming an angle with the vertical axis and said means for mounting including first means for adjusting a vertical position of the shockwave generator above the table along said vertical axis and second means for adjusting a position of the shockwave generator in a direction along said longitudinal axis.

8. In a lithotripsy work station according to claim 7, wherein the means of mounting includes a holder mounted for pivotal movement around said vertical axis, said holder having an arm with a first telescopic portion and a second telescopic portion, said first telescopic portion forming the first means and the second telescopic portion extending at said angle and forming said second means.

9. In a lithotripsy work station according to claim 8, which includes a locating system having two x-ray units, said x-ray units being mounted with a central ray of a beam of x-ray radiation emitted from each unit lying in a vertical plane in which a longitudinal axis of the patient supporting table also lies, said locating system and said holder comprising a common suspension above said patient supporting table.

10. In a lithotripsy work station comprising a patient supporting table and a single shockwave generator having a longitudinal axis and means adapted for contacting a patient including a membrane, the improvements comprising means for adjustable mounting the shockwave generator for movement around a vertical axis above said patient supporting table with said longitudinal axis forming an angle with the vertical axis.

11. A lithotripsy work station comprising a patient supporting table having a surface adapted to receive a patient, a shockwave generator, and means for adjustably positioning said shockwave generator to move around a vertical axis above said surface of the patient supporting table.

12. A lithotripsy work station according to claim 11, wherein said means for positioning the shockwave generator includes a holder rotatable around the vertical axis above said patient supporting table, said holder mounting the shockwave generator with a longitudinal axis of the generator intersecting the vertical axis at a point above the surface of the patient supporting table.

13. A lithotripsy work station according to claim 12, which includes a locating system having two x-ray units, said x-ray units being mounted with a central ray of a beam of x-ray radiation emitted from each unit lying in a vertical plane in which a longitudinal axis of the patient supporting table also lies, said locating system and said holder comprising a common suspension above said patient support table.
