Coaxial location for contact free comminution of concrements
First Claim
1. In a device for contactfree comminution of concrements in the body of a living being including a shock wave generating and reflecting system, at least one concrement locating system and a rest for said living being the improvement comprising:
- at least one equipment carrier for said shock wave system and said one or more locating systems; and
means for displaceably supporting said equipment carrier for selective positioning said shock wave system or said one locating system in a particular position with respect to said rest to thereby obtain a particular position of either and both said shock wave system and said one locating system with respect to the rest and a body having been placed on said rest, so that the shockwave system can replace said locating system in said one particular position.

Abstract
A concrement in a human body is located by an X-ray system establishing an axis through the concrement; ultrasonic equipment determines a depth coordinate value for the concrement on that axis, and a shock gyrator and focusing system is placed on that established axis for obtaining the comminution. A rest is provided for placing the body in the action zone, and for establishing a second axis in a coordinate system; the third axis is perpendicular to the latter and defines locally the direction of position change for the various types of equipment needed to carry out the aforementioned program.

15. In a device for contactfree comminution of concrements in the body of a living being including a shock wave generating and reflecting system, at least one concrement locating system and a rest for said living being the improvement comprising:
-
means for positioning the concrement locating system within an X-Y coordinate system, such that a third (Z) coordinate through the origin of the X-Y system runs through the concrement; means for measuring the Z-coordinate value of the concrement; and means for positioning the shock wave generating and reflecting system on said Z coordinate for being effective at a depth corresponding to the measured Z-coordinate value.

16. A method for contactless comminution of concrements in the body of a living being, comprising the steps of:
-
locating a concrement by means of X-rays such that an axis for a beam of X-rays runs through the concrement; marking a representation of that axis such that subsequently other equipment can be located with respect to said axis; measuring a depth value for the concrement on the axis under utilization of the representation of the axis; positioning a shock wave generating and focussing device on said axis under utilization of the representation of the axis and under further utilization of said dept value as measured; and operating said device for comminution of the located concrement. - View Dependent Claims (17, 18)
