Definitions
- the invention relates to a focusing device for a device for generating shockwaves, which is connected downstream of these and by means of which the shock waves can be aligned according to the preamble of patent claims 1 and / or 3.
- DE 44 21 938 C2 discloses such a device for producing focused acoustic waves for the therapeutic treatment of a human or animal body.
- the shock waves generated by the device are reflected between two reflection planes, which are aligned with each other so that all the reflected portions of the shock wave are bundled in a common focus point.
- the focal point represents the treatment level of the human or animal body.
- Such devices can be used for example for the destruction of kidney stones and have been part of medical technology for several decades.
- a disadvantage of such known devices for generating shockwaves has been found, for example, that the kidney stone to be crushed must be placed exactly in the focus of the shock wave, both to shatter the kidney stone with sufficient energy, as well as to exclude that adjacent human tissue through the wrong positioning of the focal point is destroyed.
- the proportion of the reflected or bundled shock waves should pass through the patient in such a way that the reflected shock wave is bundled in the axial emission direction onto a line.
- each primary shock wave is split into specific reflected portions, each of which takes a different course, so that a plurality of focus points outside of the focusing device are traversed by the components of a shockwave.
- These individual focus points form a focus line which is preferably aligned with the symmetry axis of the rotationally symmetrical body runs. Within the focus line, the patient's treatment center should be positioned.
- the advantage of positioning the patients on such a focus line is that the practitioner can treat largely independently of the depth information of the treatment site.
- both tensile and compressive wave components the z. B. for the destruction of kidney stones and for the healing or stimulation of bone tissue, tendon tendinosis, wound healing, etc. can be used specifically.
- the superimposed or temporally successive pressure and tensile or tensile and pressure wave fractions result in the medical treatment of the patient to faster therapy successes and the necessary shock wave energy can be reduced, so that the treatment time is shortened, and the adjacent tissue is not or only insignificantly injured.
- the patient does not have to be arranged precisely in a focal point and fixed in the focal point during the treatment period, but that the treatment center lies substantially in the region of the focal line, so that at the same time e.g. the kidney stone and its concrements are smashed, so that the treatment center can be placed in the area of maximum convergence without the patient having to move and reposition.
- FIG. 1 shows a first exemplary embodiment of a focusing device for reflecting shock waves generated by a device, wherein the axially proximal primary shock waves are focused into the distal region of the focal line and the axially distant focal regions are focused into the proximal region of the focal line.
- Figure 2 shows a second embodiment of a focusing device for Reflection of shock waves generated by a device and wherein the axially close primary shock waves are focused in the proximal area of the focus line and the axially distant into the distal area of the focus line,
- FIG. 3 shows a third exemplary embodiment of a focusing device for bundling a and b of shock waves by means of lens segments which have been produced by a device
- FIG. 4 shows a fourth exemplary embodiment of a focusing device for reflection of shock waves generated by a piezoelectric device
- FIG. 5 shows a fifth exemplary embodiment with a focusing device for bundling shock waves by means of a reflector, which have been produced by a cylindrical device,
- Figure 6 shows a sixth embodiment of a device for generating shock waves, which is arranged movable and freely positionable within a focusing device, in section and
- Figure 7 shows the device and the focusing device according to Figure 6 with a
- FIG. 1 shows a device 1 for generating shockwaves 2, which is arranged within a focusing device 11 ', so that the emitted shockwaves 2 are reflected by the focusing device 11 1 .
- Each area of the focusing device 11 1 is assigned a certain shock wave component 3 of the generated shock wave 2.
- the focusing device 11 1 is formed as a rotationally symmetrical body 12.
- the device 1 is on the symmetry axis 13 of the rotationally symmetrical body 12 arranged so that the source of the device 1 for generating shock waves 2 is exactly on the axis of symmetry 13.
- the inner surface of the rotationally symmetric body 12 has a plurality of reflection mirrors 14, which are shown schematically.
- the shock wave 2 thus decays into primary shock wave components 3, before these impinge on the surface of the focusing device 11 and a secondary components 4, which have been reflected by the reflection mirror 14 of the focusing device 11 1 .
- the rotationally symmetrical body 12 has an exit plane 17 through which all the reflected secondary parts 4 of the shock waves 2 run.
- the reflected secondary parts 4 of the shockwave 2 pass through a multiplicity of focal points 15, since each secondary part 4 of the shockwave 2 is bundled in a different focal point 15 which lies on the axis of symmetry 13.
- Each of the focus points 15 therefore forms a common focus line 16 which extends in alignment with the axis of symmetry 13.
- the focus line 16 is thus generated outside of the focusing device 11 1 and has approximately a length a of 0 to 25 cm.
- the secondary parts 4 of the shock wave 2 are reflected on the surface of the rotationally symmetrical body 12 in such a way that the secondary parts 4 of the shock wave 2 near the symmetry axis 13 are focused into the distal region F N of the focus line 16 and the components of the shock wave distant from the axis of symmetry 2 in the proximal region F 1 of the focus line 16.
- the corresponding reflection behavior of the reflector 12 in FIGS. 1 and 2 is achieved by the particular arrangement and / or curvature of the reflection mirrors 14.
- FIGS. 3 a and 3 b it is shown that the individual primary shock wave components 3 of the shock wave 2 are bundled by a focal lens 21 which has a multiplicity of lens segments 22, so that the primary shock wave components 3 of the shock wave 2 are deflected into a plurality of focus points 15.
- the lens segments 22 can be adjusted and have different focusing properties for the shock wave 2.
- the device 1 for generating shock waves 2 it is possible to use all known generation devices, in addition to the examples from FIGS. 1 to 3, also electromagnetic shock wave generators or piezoelectric shock wave generators.
- the corresponding reflectors 18 or surfaces must then be designed so that the technical features of this patent are met.
- the device 1 for generating shock waves 2 is arranged within the focusing device 11 ', which is designed as a parabolic mirror.
- the device 1 can be moved out of the focal point 5, in all directions.
- a conventional compass representation 6 is shown in the center of the device 1.
- the direction of movement upwards corresponds to the north orientation (N). This will continue in a similar way.
- the individual focus points 15 extend axially on the focal line 16 and, depending on the movement of the device 1, can also be arranged laterally to the focal line 16.
- Primary shock wave components 3 of the shock wave 2 generated by the device 1 arise when the device 1 is moved to the north (N) and / or to the south (S) according to the compass 6 shown.
- the characteristic configuration of the primary and secondary shock wave components 3 and 4 does not change, because the performance parameters of the device 1 are kept constant.
- a spatially enlarged treatment center can be covered, because the focus line 16 can be extended by the movement of the device 1, ie in the axial direction - this corresponds to a movement of the device 1 to the west ( W) and east (O) respectively - the primary and secondary shock wave components 3 and 4 expand and the device 1 moved to the north (N) and south (S) shifts the focus line 16 in the lateral direction.
- Such a lateral arrangement of the shock wave components 3 and 4 can be seen by the designations F-is, Fis and F NS .
- the number 1 means that this is the first focal point on the focus line 16
- the letter I refers to the middle focus point and the letter N to the last focal point of the focus line 16.
- the other letters N, O, S, W indicate the focal point, which arises by the corresponding movement of the device 1, for example, to the north.
- the device 1 is held supported in the focusing device 11 'in a thread 23.
- One at the Device 1 mounted adjusting spindle 24 acts as an adjusting member for positioning, movement and / or fixation of the device 1.
- the device 1 can thus be moved from the outside along the axis of symmetry 13 of the focusing device 11 '. Consequently, the focus line 16 expands and there is a maximum distance b, which is greater than the distance a in the figure 1 between the first and last focus points 15th
