Abstract
Abstract A lithotripsy work station has a table for supporting a patient which is adjustable in three spatial directions, with at least one shock wave generator disposed below the table. The shock wave generator is adjustably mounted so that movement of its focus to an isocenter is possible. For locating renal calculi, an x-ray examination apparatus is provided which transilluminates the patient at various angles. A plane defined by two central rays of the x-ray apparatus proceeds through the longitudinal axis of the patient supporting table, such that one radiator of the x-ray system emits radiation in an a.p.-direction and a second radiator of the x-ray apparatus emits radiation in the caudal-cranial direction. The x-ray radiators can be moved out of the work area, as needed. The work station can be used for shock wave treatments, for urological treatments and for x-ray examinations.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
209 words
A lithotripsy work station comprising: a patient support table having a longitudinal axis for selectively positioning a patient thereon with respect to a fixed point in space; at least one shock wave generator for disintegrating calculi disposed beneath said patient support table, said shock wave generator having a membrane for coupling said shock wave generator to the skin of said patient, and said patient support table having an opening therein through which said shock wave generator can at least partially extend; means for mounting said shock wave generator for permitting adjustment of the focus of said shock wave generator to said fixed point in space; and an x-ray examination means for transilluminating said patient at selected angles for locating calculi, said x-ray examination means including two x-ray radiators disposed above said patient support table and each having a central ray, a central ray of one of said radiators being emitted in a direction perpendicular to said patient support table and the central ray of the other radiator being emitted in an oblique direction with respect to said patient support table, with both of said central rays proceeding in a common plane which includes said longitudinal axis of said patient support table and intersecting in said fixed point in space
Claim 2
Dependent Claim
209 words
A lithotripsy work station comprising: a patient support table having a longitudinal axis for selectively positioning a patient thereon with respect to a fixed point in space; at least one shock wave generator for disintegrating calculi disposed beneath said patient support table, said shock wave generator having a membrane for coupling said shock wave generator to the skin of said patient, and said patient support table having an opening therein through which said shock wave generator can at least partially extend; means for mounting said shock wave generator for permitting adjustment of the focus of said shock wave generator to said fixed point in space; and an x-ray examination means for transilluminating said patient at selected angles for locating calculi, said x-ray examination means including two x-ray radiators disposed above said patient support table and each having a central ray, a central ray of one of said radiators being emitted in a direction perpendicular to said patient support table and the central ray of the other radiator being emitted in an oblique direction with respect to said patient support table, with both of said central rays proceeding in a common plane which includes said longitudinal axis of said patient support table and intersecting in said fixed point in space
Claim 3
Dependent Claim
40 words
A lithotripsy work station as claimed in claim 1 further comprising: x-ray exposure means for generating an x-ray image from each of said x-ray radiators; and means for accomodating attachment of said x-ray exposure means beneath said patient support table.
Claim 4
Dependent Claim
117 words
A lithotripsy work station as claimed in claim 1 having two shock wave generators, and further comprising: a common support for said two shock wave generators; each shock wave generator having a central wave propagation axis and said shock wave generators being mounted on said support such that their respective propagation axes intersect at an angle; means for pivoting said common support about an axis parallel to said longitudinal axis of said patient support table to position one of said shock wave generators with its propagation axis proceeding through said fixed point in space; and means for adjusting the position of each shock wave generator relative to said common support along the direction of its propagation axis.
Claim 5
Dependent Claim
40 words
A lithotripsy work station as claimed in claim 1, wherein said x-ray examination means includes means for adjusting the radiator having a central ray emitted perpendicular to said patient support table at right angles relative to said patient support table.
Claim 6
Dependent Claim
39 words
A lithotripsy work station as claimed in claim 1, wherein said x-ray examination means includes means for moving the radiator having a central ray emitted in an oblique direction out of a work area above said patient support table
Claim 7
Dependent Claim
35 words
A lithotripsy work station as claimed in claim 1 further comprising a common housing for both of said x-ray radiators, and means in said housing for vertically adjusting the position of each of said radiators.
Claim 8
Dependent Claim
23 words
A lithotripsy work station as claimed in claim 6 wherein said housing includes means for supporting said housing on a horizontally disposed surface.
Claim 9
Dependent Claim
24 words
A lithotripsy work station as claimed in claim 7 wherein said horizontal surface is a horizontaly extending arm connected to a vertically disposed surface.
Claim 10
Dependent Claim
34 words
A lithotripsy work station as claimed in claim 8 for use in an examination room having a floor, wherein said vertically disposed surface is a post supported on the floor of said examination room.
