The support plate can be adjusted relative to the base in three coordinate directions so that the patient can be positioned in a desired position. The support plate can also be pivoted about horizontal axes (13, 19) that are perpendicular to its longitudinal axis. An independent claim is made for a method for positioning a patient by pivoting the support about horizontal axes perpendicular to the couch longitudinal axis.

Description

The present invention relates to a treatment couch for storage of Patients.

Such treatment couches basically have a deck plate for the patient and a couch plate on a floor, such as in a treatment room, supporting Based on. The deck plate can of course be upholstered, so it has to be not necessarily a rigid plate in the narrower sense. Furthermore, can the deck plate of course also be in several parts, such as various plate-like Composed of elements.

Such treatment couches are in some cases multiple adjustable to the patient to bring in a suitable position. The invention is based on one in at least two mutually substantially vertical adjustment directions adjustable treatment couch off.

In particular, adjustment options along a longitudinal direction are possible the deck plate along a transverse horizontal direction and finally along a vertical direction. For simplicity, the directions hereinafter referred to as X, Y and Z, wherein Y for the longitudinal direction, X for the horizontal direction substantially perpendicular thereto and Z for vertical stands.

The present invention is based on the technical problem, one in the described To specify a way adjustable treatment table with a simplified design.

The invention is directed to a treatment couch for storage of a patient with a reclining panel for the patient and a base for supporting the reclining panel on a floor, with the deck plate opposite the base along at least two mutually substantially perpendicular directions is adjustable to the position position Adjust the patient, characterized in that the deck plate in the adjustment about an axis of rotation perpendicular to its longitudinal direction is pivoted.

The invention is characterized in that at least one of said adjustment by a pivotal movement mechanism with a rotation axis should be solved. In this case, the axis of rotation perpendicular to the longitudinal direction, ie perpendicular to the Y-direction, lie, so that in a pivoting movement around a to the Z axis parallel axis of rotation an X-adjustment and at one to the X-direction parallel axis of rotation gives a Z-adjustment.

It has been shown that the conventional linear guides at two, esp. in accordance with the invention preferred three adjustment axes to a considerable technical Expense and thus relatively expensive constructions lead. I. d. R. will be for the X and the Z-adjustment directions each used multiple drives. In contrast, can the X-adjustment and the Z-adjustment relatively easily by a Perform pivoting movement about the mentioned axes. It can in particular Drives are saved, so in the case of a manual adjustment corresponding Actuators with manual operation or otherwise motor drives. It is even possible, although not absolutely necessary, only a single drive for the To provide pivoting movement about a rotation axis. The invention is Incidentally, with regard to all axes of rotation, in each case preferably motor drives, however, there are also treatment couches with hand-operated adjustment options or those with partly motorized and partly hand-operated adjustment options included.

Preferably, both the X-adjustment and the Z-adjustment in the inventive Manner solved via a pivoting mechanism, however essential advantages of the invention are already achieved if only one of both adjustment is carried out in the manner according to the invention.

A positioning of the axis of rotation for the Z-adjustment has proven particularly useful (ie the X-parallel axis of rotation) in the region of the foot end of the deck plate and further a positioning of the axis of rotation for the X-adjustment (ie the Z-parallel Rotation axis) from the center of the couch on the side of the foot end, in relation to on the Y-longitudinal direction. This will be in the body center already in the adjustment and certainly at the head end as a result of a pivoting movement about the axis of rotation considerable Lifting heights reached. Specifically, this means that the X-parallel pivot axis in terms of the longitudinal extent of the deck plate seen from the foot within 10% of the longitudinal extent, the reference value being 100% the total length of the deck plate without the below explained in more detail optional Headrest means. In the same sense, the Z-parallel pivot axis is preferably within 30% of the longitudinal extent seen from the foot, especially preferably within 25% and most preferably within 20%.

The motor adjustment for the Z-adjustment can in a preferred embodiment a motor, such as an electric motor, with one provided on an output shaft Coupling and a coupling belt driven by the coupling belt be. For example, the coupling wheel and coupling band may be to act a gear / toothed belt or gear / chain combination. The Coupling strap carries a driver, which is either the adjustable part of the treatment couch entrains or with the during Z-adjustment not moving Part of the treatment couch is coupled. In the former case, the engine is in relation fixed to the during the Z-adjustment fixed part of the treatment couch, in second case compared to the part of the treatment couch covered by the Z-adjustment stationary. In this way, the arcuate adjustment be realized by a simple rotary drive. As an illustration is referred to the embodiment.

A preferred embodiment of the X-adjustment can be conventional per se Linear drive, such as a Spindelhubtrieb or rack and pinion, be to his both ends, d. H. at a respect to the linear motion stationary and a through the linear movement moving end, is articulated. Through the articulated mounting can the linear linear actuator in the actually arcuate Pivoting movement can be used to the rotation axis according to the invention.

Preferably, the treatment couch has a headrest for supporting the patient's head on, which is adjustable relative to the deck plate. This adjustability can be used in addition to the already described adjustability of the deck plate in treatments be of interest to the head. In the interest of this invention however, especially a headrest which is in a substantially vertical Z-direction relative to the deck plate is adjustable, in which a drive for the Z-adjustment the headrest is built into the headrest and the headrest together with the drive as a module of the treatment table is removable.

The invention thus assumes that an adjustable headrest is present. The drive of this headrest, whether it is now a manual drive, about a Hand crank or an adjusting wheel, or to a motor, esp. Electric motor, acts, should be part of the headrest. This means that the headrest is considered independent Assembly unit is mounted on the treatment table and can be removed without doing so the drive itself would have to be disconnected from the headrest. The drive should be so if necessary via signal lines or supply lines with the rest of the treatment couch be coupled, for example because he supplies together with local engines or is controlled by a common control. The connection between The headrest and the treatment couch is therefore limited to static removable fasteners and cables.

The prior art has instead installed the drive in the treatment couch, namely, for example, as an electric motor, via a spindle gear a push rod drives, which transmits the adjustment movement to the headrest. This has the Disadvantage that in the production no separately pre-assembled headrest module used can be done by just a few screws or the like must be connected to the treatment couch. Furthermore one can with the Solution according to the invention also during maintenance or retrofitting Treatment couch can achieve benefits by having the headrest as a complete functional unit decrease and because of need for repair or updating or Replacement request can be exchanged for another headrest.

Preferably, the vertical Z-adjustability of the headrest by a pivoting movement realized, to which only a single drive is required. Esp. can do it substantially perpendicular to the vertical Z-direction and also substantially perpendicular to the longitudinal extent of the treatment couch extending Pivot axis on the side facing the treatment couch or in hinge points be provided on the treatment couch.

Also preferred is a rack drive, esp. In conjunction with the described pivoting movement. By way of illustration, the embodiment directed. A rack and pinion drive is i. d. R. easier and less problematic than For example, a driven spindle gear or a linear motor. Preferably The rack drive has a guide for the rack itself, the turn is rotatable about the tilting of the rack during the Balance the swivel movement of the headrest. The rack is further preferably hollow and can then serve, in a protected manner lines between the headrest and the treatment couch.

Basically, in this invention, motor drives the Z-adjustment of Headrest preferred. This applies esp. For electric motor drives. At another preferred embodiment, these are in an adjusting movements of the Treatment couch tuned manner so that esp. An automatic Tilt compensation of the headrest can be done when the treatment couch or whose deck plate is tilted. This tilting movement of the deck plate can u.a. thereby occur that a vertical Z-adjustment of the deck plate by a Pivoting movement thereof takes place and the associated pivot axis of the Headrest is located away. The automatic tilt compensation then allows a Keeping constant the angular orientation of the headrest, i. for example one consistently horizontal position of the headrest. This is particularly advantageous for treatments of the patient's head.

In a further preferred embodiment, the headrest also has an X-adjustment relative to the deck plate, and preferably also by a pivoting movement about a now parallel to the Z-direction Axis of rotation. This adjustment is preferably motorized. Again, it is preferred that the X-adjustment in one (mechanical or motor) on an X-adjustment the deck plate can be adapted to swivel-X adjustments the deck plate a corresponding angle compensation in the headrest to obtain. For then the patient's head can be moved in the X-direction without being in the area of the headrest lying on the patient's head an angle error occurs. However, the angle errors that occur when on This option is omitted, not so great that this is the case for all applications would lead to a problem.

For the technical implementation of the X-adjustment of the headrest by a Swivel movement apply mutatis mutandis to the versions of the Z-adjustment.

When a headrest according to the invention mounted in a modular manner on the treatment couch is adjusted, it can lead to a risk of trapping. This applies esp. For a Pivoting the distal end of the headrest relative to the treatment couch, the upper lying surface of the headrest moves towards the treatment couch becomes. The invention provides in this case to leave sufficient distances, so that esp. The treatment staff is not subject to any risk of jamming. On the other hand for the patient created an at least substantially continuous lying surface should be, it is preferred, an already favorable pad on the headrest extend beyond their fixed parts, so that such safety gaps be covered. As an additional measure can be provided that Upholstery on the headrest only via a Velcro and possibly further detachable by direct removal fasteners, such as centering pins o. Ä to keep. If a cushioning effect emanates from the pad, then this can easily detach from the Velcro and other possible fasteners, thus greater clamping forces can be avoided.

It has already been stated that in the invention preferably the Z-adjustment and the X-adjustment done via the described pivoting movements. on the other hand it is inventively preferred, the Y-adjustment, so the adjustment in the longitudinal direction, further in a conventional manner via a linear guide make. Since the Y-adjustment is not gravitationally parallel, it can be here sufficient to use a single linear drive, such as a spindle drive, and Incidentally, the deck plate can be displaced in Y-direction. In the invention Incidentally, it is preferable that the Y-adjusting movement relative to the fixed base is done and further preferred that the X-adjustment of the Z-adjustment mechanism "takes along", so to speak between the Y-adjustment and the Z-adjustment is interposed. This can also be the X-adjustment free from gravitational effects and can be the Z-adjustment on the movement of comparatively smaller components of the entire treatment couch restrict.

The treatment couch can have a support leg, which is taken along with the X-adjustment is and with respect to the X-adjustment rotary axis remote part of Treatment couch is mounted, preferably in the vicinity of the shoulder or head area of the patient. This may result in an extension of the X motion due the support foot improved overall stability can be achieved.

A preferred field of application for the treatment couch according to the invention lies in components of medical devices for the treatment of the head and in particular of the eye. Furthermore, the invention preferably relates to devices for Treatment of the human body, however, can also be used in treatment couches Animals are used. A particularly preferred area is laser surgery in the human eye, in which the treatment couch according to the invention the treated eye placed in the correct position for laser surgery can be.

Finally, the invention also relates to a method for storing a Patients using the described treatment couch. The above and the following description of the treatment couch in its device Details are at the same time as a disclosure of said method understand.

Fig. 1 shows the side view of a treatment couch according to the invention, wherein some technical details of interest are shown when closed Housing would not be visible from the outside. In Fig. 1, 1 is a deck plate denotes, on which a mattress 2 is located and at the right end to a vertical Completing the deck 1 a headrest 3 is mounted.

The deck plate 1 is mounted in a manner to be shown in more detail on a base 4, which rests on Verstellfüße 5 on a floor 6.

In the base 4 is fixed to a linear drive with an electric motor 7 and one of this driven spindle lifting rod 8 attached. The spindle lifting rod 8 is on a console 9 mounted, via which the electric motor 7 and the spindle lifting rod. 8 can move a first intermediate plate 10. The first intermediate plate 10 is over on a rail 11 running linear guides 12 in Fig. 1 horizontal direction and thus displaceably mounted in the longitudinal direction of the deck plate 1. This direction thus corresponds to the Y direction.

The first intermediate plate 10 carries about 17% -18% of the longitudinal extent on the side of the foot (drawing not to scale) a storage 13 with in Fig. 1 vertical Axis of rotation. About this storage 13 is a second intermediate plate 14 opposite the first intermediate plate 10 about the vertical axis through the bearing 13 rotatable held. In this case, the second intermediate plate 14 via a roller designated 15 supported on a running surface 16 of the first intermediate plate 10 and on the other hand connected to a driver 17, the one below in more detail described timing belt is driven. The toothed belt runs in a in Fig. 1 with 18 designated housing. Thus, the second intermediate plate 14 around the be pivoted by the bearing 13 running vertical axis, which in the Y direction from the bearing 13 spaced areas, ie in particular in the area the headrest 3, an adjustment in a direction perpendicular to the plane of the drawing, namely the X-direction, corresponds.

At the second intermediate plate 14 is in the foot region (about 7% -8% of the longitudinal extent, Drawing not to scale) a pivot bearing 19 is provided on which the Liegeplatte 1 is articulated. In the head area, the deck plate 1 is articulated with a Spindle lifting rod 20 is connected, which is linearly driven by an electric motor 21 is in turn hinged to a mounting platform of the second intermediate plate 14th is appropriate.

FIG. 2 shows the side view according to FIG. 1 with some deviations with respect to the adjustment positions. The comparison of FIGS. 1 and 2 shows, on the one hand, that by extension the spindle lifting rod 20 from the electric motor 21, the deck plate 1 to the Rotated pivot axis 19 and thus in the head area in the vertical direction, ie in the Z direction, can be raised.

Furthermore, the comparison of Figs. 1 and 2 shows that by moving the spindle lifting rod 8, here pulling in the electric motor 7, the first intermediate plate 10 and so that the second intermediate plate 14 and the deck plate 1 moves in the Y direction can be.

Fig. 3 shows a plan view of the treatment table of FIGS. 1 and 2, wherein in particular, the mechanism for driving the driver 17 shown in more detail is. An electric motor 22 with lying in the Z direction of rotation drives a toothed belt 23, which is guided over four pulleys 24 and attached to the driver 17 is. A rotation of the output shaft of the electric motor 22 thus moves the Carrier 17 in the X direction and thus moves the second intermediate plate 14 relative to the first intermediate plate 10 in the X direction. This movement is illustrated in FIG. 4, wherein in solid lines with the head end according to FIG. 4 down adjustment in the X direction and in dashed lines in opposite set direction took place X-adjustment is located. The clarity the reference numbers are omitted in FIG. 4. The rotation takes place around the Axis through the bearing 13. The roller 15, which in relation to the X direction approximately centrally below the second intermediate plate 14 remains within the shown in Fig. 4 Adjustment on the over the entire X-width of the first intermediate plate 10th continuous running rail 16.

The figures also show that the headrest 3 via two levers 25 hinged to the Couch plate 1 is attached. Fig. 1 and Fig. 2 further show that in the Z direction below the levers 25, a further Spindelhubstange 26 provided with an electric motor 27 is. The electric motor 27 is hinged to the headrest 3. Further the spindle lifting rod 26 is hinged to the deck plate 1. The comparison 1 and 2 shows that by retraction and extension of the screw jack 26 in and from the motor 27, a tilting movement of the headrest 3 about the hinge axis of the lever 25 takes place on the deck plate 1, with the particular automatic Tilt compensation for Z-adjustment of the deck plate 1 can accomplish. This tilt compensation is clearly visible in FIG. In addition, the Of course, headrest 3 can also be tilted in other ways, if desired is. The automatic tilt compensation is done by appropriate tuning the control of the motor 27 to the drive of the motor 21st

Fig. 5 shows the headrest of the treatment table in detail, in Sectional view seen in the X direction.

The headrest 3 has a holding plate 28, the detailed structure of the following Figures becomes even clearer and the fastening screws 29 on the Treatment couch itself can be attached. The holding plate 28 is already in the Fig. 1 - 4 shown symbolically, but not numbered.

The fastening screws engage in a metal plate 30 with corresponding threads, to relieve the otherwise made of plastic retaining plate 28. she also hold in the holding plate 28 a hinge box 31, in which already based Fig. 1 - 4 mentioned and shown there rack 26 is articulated.

As the following figures illustrate in more detail, is on the support plate 28 via two above or below the plane lying joint boxes with corresponding rocker arms hinged the actual head shell 32 of the headrest 3. This head shell 32 consists of an anatomically shaped upper part 33 and an attached below Housing part 34, in which the already mentioned rack 26 protrudes. In the housing part 34 is arranged below the plane of the electric motor 27, which is already shown in Fig. 1, with a clearly visible in Fig. 5 output pinion built-in. Further, a guide 35 is provided which holds the rack 26 and leads, but in which this is displaceable. The guide 35 can be about the axis of the Output pinion of the electric motor 27 are pivoted and thus in the movement the headrest 3 a pivoting movement of the rack 26 about the articulated Attachment in the hinge box 31 follow.

The headrest 33 consists essentially of a soft foam pad 36, via a hook and loop fastener 37 on an upper plate of the housing part 34th is appropriate. To facilitate insertion of this pad 36 may additionally Not shown here centering pins may be provided.

This plate is, as Fig. 5 shows in the horizontal position of the head rest 33 something spaced from the holding plate 28, so protrudes in the holding plate 28 facing Direction not far beyond the remaining housing part 34 addition. Therefore arises at this point a slot between the housing part 34 and the holding plate 28, the is surmounted by the pad 36. There is no risk of jamming because of this Slot is sized so large that operators do not pinch their fingers easily can. Furthermore, the pad 36, which is in a downward movement quite closer to the support plate 28 can draw as drawn in Fig. 5, according to dodge above. This follows on the one hand from a certain deformability and is on the other hand, an advantage of the Velcro fastener 37.

Fig. 6 shows an alternative embodiment to Fig. 5, in the same way at a Treatment couch according to FIGS. 1 - 4 may be attached. The following will be only the differences compared to FIG. 5 received. First, in Fig. 6 a centering pin 38 is shown, the pad 36 on the upper plate of the housing part 34 of the headrest 32 holds. On the other hand, the electric motor 27 is here replaced by a hand crank drive 39 with a worm gear 40, 41. The gear 41 of the worm gear is located on a common axis a pinion corresponding to the output gear 27 of FIG. 5 for driving the Rack 26.

The hand crank 39 has a fold-out pin to facilitate cranking on, which is designated 42. It can be seen that the manual drive in the same way Part of the headrest 3, as for the electric motor 27 with the associated Drive parts in Fig. 5 applies. Incidentally, there are no fundamental differences to Fig. 5.

Fig. 7 illustrates the headrest 3 of FIG. 6 in an exploded view. One recognises, that the pad 36 has a somewhat semicircular shape and the housing part 34th the headrest 32 is adapted to this semicircular shape and the pad 36 of keeps outside. It also recognizes the over the housing part 34 protruding part of the Pad 36 and an associated semicircular recess in the holding plate 28, in the this supernatant protrudes. In addition to the hinge box 31, FIG. 7 shows two more Joint boxes, which are designated 43 and are held by screws 44. These joint boxes 43 carry hinge pins, which on the housing part 34 of the headrest 32 are mounted on the other hand in the recognizable receiving holes of Retaining plate 28 is inserted and screwed with the screws 44. The fixing screws Incidentally, 29 and 44 also serve for fastening the retaining plate 28 on the other treatment couch in a manner not shown. she are through a plate of the treatment couch through by the holding plate 28 with the joint boxes 31 and 43 screwed.

Further, Fig. 7 shows in perspective the guide 35 for the rack 26 and the Worm gear 40, 41 of FIG. 6.

Finally, it can be seen that the rack 26 is designed as a hollow tube. In not shown manner can be laid in the rack 26 so that electrical lines be, for example, if instead of the manual drive 39 - 42 an electric motor drive 27th is used.

Fig. 8 shows an analogous representation to Fig. 7, but to the embodiment from Fig. 5. Further, in the illustration of Fig. 8 for illustration, the pad 36 omitted, the Fig. 7 shows. Incidentally, the explanations to the figures 5-7 referenced.

FIGS. 9 and 10 show a side view of the headrest 3 from FIGS. 6 and 7 with a lower and an upper adjustment position and a perspective view the headrest 3 for a better understanding of Fig. 7. Here are no reference numerals drawn in order to improve the pictorial representation.

In Fig. 9 can be seen esp., That an adjustment with the manual drive 39 - 42 to leads that the headrest 32 relative to the support plate 28 moves upward and it is supported on the rack 26 and the hinge box 31. The same applies vice versa for an adjustment down. This may be in the context a motorized embodiment of a Z-adjustment of the deck plate 2 of the treatment couch adapted to a constant, for example to ensure horizontal holding of the patient's head. This is especially for the Application of the treatment couch according to the following explanations of importance.

It can be seen that the rack 26 or more generally the Längenverstellelement of the drive below the pivot axis forming joints arranged is. This is advantageous because then smaller length changes due to a Headrest adjustment on the level of the patient's head (in the Y direction) occur and the drive thus better for operation or for removal and installation from below is accessible.

Fig. 11 shows a schematic plan view of a further embodiment of the Clarification of the optional feature of an X-adjustment of the headrest 3. An the deck plate 1 with the Z-parallel axis of rotation 13 for the X-adjustment is the already mentioned holding plate 28 in this case via a motor-driven Rack 46 with motor 45 on an outer side (seen in the X direction) and attached via a hinge 47 on the opposite outer side. In order to can the support plate 28 relative to the deck plate 1 adjusted about the axis of rotation 47 be so that angle error due to X-adjustments of the deck plate 1 to the Rotary axis 13 can be compensated. The case occurring in this example Y error - the axis of rotation 47 is not centered - can in turn by a taken into account automatic consideration in the Y-adjustment of the deck plate 1 if desired. Incidentally, the X-adjustability of the headrest 3 Of course, be beneficial for other reasons.

Fig. 12, in turn, shows another optional embodiment in which the X-adjustable Part of the treatment couch via an adjustable support leg 48 on the Ground is caught. This support leg 48 is shown here only symbolically and may be driven in practice to move during adjustment movements of the Lift off the ground and set up after adjustment for stabilization. alternative The lower end of the support leg 48 can also roll with a rolling on the ground Be provided roll or a sliding surface. The support leg 48 is on a front side Plate attached, in turn, with the already mentioned intermediate plate 14th is connected, which in turn pivots about the axis 13 relative to the base 4 can be.

The illustrated treatment couch is an integral part of one not in further Details shown and known per se laser surgery device for treatment of ametropia in the human eye. Above the headrest 3 is the head attached to this device and directs a running in the Z direction laser beam in the eye, which brought with the treatment couch in the appropriate position must become. By X-adjustment can between the two eyes of the patient be switched back and forth. The optical adjustment options of the laser device so that only the fine movements of the laser beam at the actual must Cover treatment. The positioning of the patient is independent of this over the treatment couch. In particular, the X-adjustment can also do so be used to facilitate the patient's entry.
