Definitions
- the present invention relates to a treatment table for the storage of patients, specifically on a treatment table with a knee support for more comfortable storage of the legs of the patient.
- Treatment couches for patient storage basically have a couch plate for the patient and a base supporting the couch panel on a floor, such as in a treatment room.
- the deck plate can be upholstered, so it does not necessarily have to be a rigid plate in the narrower sense.
- the deck plate may also be multi-part, composed of various plate-like elements.
- Knee braces are also known in the dental treatment tables. They have a thigh portion for supporting the thighs of the patient, which is angled relative to a torso portion of the couch. The patient is therefore not forced to lie flat while lying in the dental treatment, but can adopt a more comfortable posture in which his legs are supported by a knee brace so high that the thighs are slightly angled relative to the torso.
- knee brace is here thus meant a shaping of the platform in such a way that the knees are slightly “raised” stored.
- the EP 1 346 668 A1 shows a three-piece deck plate whose individual parts are rotatably connected to each other and their respective angle can be adjusted by motorized.
- the rotational movements of the individual joints are coordinated so that a person lying on the platter felt no unpleasant pressure pain in the corresponding body parts during the automatic angle adjustment of the couch.
- the US 4,258,445 shows couches for bedridden patients.
- the loungers are designed in sections movable. In particular, the patient's legs can be moved independently. This serves to imitate walking movements for bedridden patients.
- the WO 02/076267 A1 shows an adjustable lounger, which in rooms with limited space, z. B. in boats or cabs of trucks, is used.
- the lying surface consists of an upper body area with integrated head area, a seat area as well as a thigh and lower leg area. Except for the seat all areas of the bed can be coupled coupled or uncoupled angle, with an automatic drive mechanism is installed to save space in the frame.
- the US 6,108,839 shows a collapsible hospital bed, the lying surface has manually adjustable sections for the upper body area, the seat and thigh and lower leg area.
- the bed is in the folded state on roles and can then easily moved as a whole who the.
- the mechanics of the bed is realized particularly cost-effectively.
- the DE 39 12 185 A1 shows a bed with a slatted frame, the individual sections are mutually adjustable in angle.
- the transverse strips of the slatted frame and its frame consist of cut extruded profiles which each have an advantageous cross section.
- the invention is based on the technical problem of specifying a treatment couch for the storage of patients with an improved knee brace.
- the invention is directed to a treatment couch for supporting a patient with a patient support plate having a torso portion for supporting the upper body of the patient and a base for supporting the support plate on a floor, the bed plate having a knee brace facing one characterized in that the knee brace is slidable relative to the upper body region in the longitudinal direction of the treatment couch, so that the distance between a fixed on the upper body portion point and the upper part of the abdominal area the hip-side beginning of the thigh portion at which the thigh portion comes closest to the upper body area, can be changed.
- the invention is also directed to a medical device with such a treatment table and to a corresponding method for storage of a patient.
- the treatment couch according to the invention has a knee brace with a thigh portion angled relative to the upper body area of the bed plate.
- this knee brace is displaceable relative to the upper body region in the longitudinal direction of the treatment couch, ie in the direction pointing from the foot to the head of the patient or vice versa.
- This adjustability is conceptually distinguishable from the already known from dental treatment tables Verkippiana the upper body portion of a treatment couch against the thigh portion of the knee brace.
- this invention is initially concerned with an at least substantially translatory displacement, ie with the distance between a point fixed on the upper body section, for example the upper end of the upper body section, and the hip-side beginning of the thigh section, at which the upper leg section is closest to the upper body region comes, is changed.
- the treatment table can be set particularly favorable to different body sizes of the patient.
- medical treatments of body parts in the area of the upper body, head or upper limbs it is possible, in particular, to prevent the location of the area to be treated from becoming very different for patients of different sizes.
- the possibilities of the invention thus go beyond a longitudinally adjustable separate headrest, because the adjustment range of such a headrest is naturally limited, if not to be taken in large patients gaps between the headrest and upper body area of the platform.
- the knee brace is additionally "height adjustable", d. H. that the knee-side end of the thigh section can be raised. This can be done in a translatory manner, but preferably the thigh section is tiltable relative to the upper body region of the deck plate.
- the knee brace in addition to the thigh portion, also has a lower leg portion which is angled relative to the thigh portion so as to provide a convex curvature or a convex curvature when viewed from the side of the knee of the patient.
- the lower leg portion is constructed so that it is taken in the above-mentioned lifting of the vice Indeeden end of the thigh portion with its knee-side end and thereby the foot-side end of the lower leg portion approximately at the same height, in particular approximately in the area of escape of the upper body portion of Medplatte, remains. This adjusts the height of the convex curvature or the convex curvature, without affecting the height of the patient's foot position.
- the thigh portion is hinged at its hip-side end to another component, in particular a bearing plate, which in turn is displaceable in the longitudinal direction.
- another component in particular a bearing plate
- the knee-side end of the thigh section is articulated via a lever to a further, ie second component, which is displaceable independently of the first component in the longitudinal direction.
- the second component may be a bearing plate. The lever is thus hinged on the one hand to the second bearing plate and on the other hand to the knee-side end of the thigh portion.
- a common longitudinal displacement the two components thus displaces the thigh portion in the longitudinal direction and, when the lower leg portion is taken with its foot-side end of the second bearing plate, with the entire knee brace.
- a relative movement between the two bearing plates changes the distance between the bearing plate-side hinge axis of the lever and the hinge axis between the hip-side end of the thigh section and the first bearing plate, so that the lever is raised or lowered and thus the Anwinkelung the thigh section is changed.
- the first and the second bearing plate or, more generally speaking, the first and the second component can each be displaceable via longitudinal rails and, in a particularly preferred embodiment, can be driven and thus adjustable by means of locking bars integrated with the longitudinal rails.
- a single longitudinal rail would be sufficient, but a plurality of longitudinal rails, in particular two longitudinal rails are preferred, in each case in the region of the lateral edge of the deck plate.
- the integrated spindle drive can be configured such that, on the one hand, guides of the displaceable components can slide over smooth areas of the guide rails, while, on the other hand, at least one guide element provided with an internal thread, which serves as a nut, is driven on a threaded section on the respective guide rod.
- one of two laterally mounted guide rods can be provided in each case for driving one of the displaceable components.
- at least two non-driven guides per displaceable component which extend beyond the guide provided with the nut are preferably provided, of which at least one runs on the respective other guide rail. This too is illustrated in the exemplary embodiment.
- the treatment couch according to the invention is adjustable not only in terms of the described adjustment of the knee brace, but also in others Respect.
- the deck plate should preferably be adjustable relative to the base along at least two mutually substantially perpendicular directions in order to adjust the position of the patient, moreover, for example, to be able to make a fine positioning of the head relative to a medical technical device.
- the bed plate may be pivotable in the adjustment about a rotational axis lying perpendicular to its longitudinal direction.
- This embodiment is thus characterized by the fact that at least one of said adjustment options should be solved by a pivoting movement mechanism with a rotation axis.
- the axis of rotation is perpendicular to the longitudinal direction, the so-called. "Y-direction", so that in a pivoting movement about a vertical "Z-axis” parallel axis of rotation a horizontal "X-adjustment” and at one to the horizontal "X-direction" parallel axis of rotation results in a "Z-adjustment".
- both the X-adjustment and the Z-adjustment via a pivoting movement mechanism are solved, however, significant advantages of the invention are already achieved when only one of the two adjustment is carried out in this way.
- a positioning of the axis of rotation for the Z-adjustment (ie the X-parallel axis of rotation) in the area of the foot end of the deck plate and also a positioning of the axis of rotation for the X-adjustment (ie the Z-parallel axis of rotation) from the middle of the bed has proven particularly useful on the side of the foot end, with respect to the Y longitudinal direction.
- the X-parallel pivot axis is approximately within 10% of the longitudinal extent with respect to the longitudinal extent of the deck plate from the foot end, the reference amounting to 100% of the total length of the deck plate without the optional optional headrest.
- the Z-parallel pivot axis is preferably within 30% of the longitudinal extent seen from the foot end, more preferably within 25% and in the best case within 20%.
- the motor adjustment drive for the Z adjustment can be a motor, for example an electric motor, with a coupling wheel provided on an output shaft and a coupling belt driven by the coupling wheel.
- the coupling wheel and coupling belt may be, for example, a gear / toothed belt or gear / chain combination.
- the coupling band carries a driver, which either entrains the adjustable part of the treatment couch or is coupled to the part of the treatment couch which is not moved during the Z adjustment.
- the motor is stationary with respect to the fixed during the Z-adjustment of the treatment couch, in the second-mentioned case relative to the detected by the Z-adjustment of the treatment couch stationary. In this way, the arcuate adjustment can be realized by a simple rotary drive.
- a preferred embodiment of the X-adjustment can be a per se conventional linear drive, such as a Spindelhubtrieb or rack and pinion, which is articulated at its two ends, ie at a respect. The linear motion and an end moved by the linear movement end. Due to the articulated mounting of the linear linear actuator can be used in the actually arcuate pivoting movement about the rotation axis according to the invention.
- the treatment table on a headrest for supporting the patient's head which is adjustable relative to the deck plate.
- This adjustability may be of interest in addition to the already described adjustability of the platform for treatments on the head.
- a headrest which is adjustable in a substantially vertical Z-direction relative to the deck plate, in which a drive for the Z-adjustment of the headrest is installed in the headrest and the headrest together with the drive as a module is detachable from the treatment couch.
- the drive of this headrest is to be part of the headrest.
- the drive should therefore at most be coupled via signal lines or supply lines to the other treatment couch, for example because it is supplied together with local motors or is controlled by a common control.
- the connection between the headrest and the treatment bed is therefore limited to static releasable fasteners and lines.
- the prior art has instead installed the drive in the treatment couch, for example, as an electric motor which drives a push rod via a spindle gear, which transmits the adjustment movement to the headrest.
- the drive in the treatment couch for example, as an electric motor which drives a push rod via a spindle gear, which transmits the adjustment movement to the headrest.
- This has the disadvantage that in the production no separately pre-assembled headrest module can be used, which only needs to be connected by some mounting screws or the like with the treatment table.
- one can achieve advantages with the solution according to the invention in the maintenance or retrofitting of a treatment table by the headrest can be removed as a complete functional unit and can exchange for another need for repair or updating or modification request against another headrest.
- the vertical Z-adjustability of the headrest is realized by a pivoting movement, to which only a single drive is required.
- Esp. may be substantially perpendicular to the vertical Z-direction and further substantially perpendicular to the longitudinal extent of the treatment couch extending pivot axis may be provided on the side facing the treatment couch or in articulation points on the treatment couch.
- a rack and pinion drive is i. d. R. easier and less problematic than, for example, a driven spindle gear or a linear motor.
- the rack drive has a guide for the rack itself, which in turn is rotatable to compensate for the tilt of the rack during the pivotal movement of the headrest.
- the rack is also preferably hollow and may then serve to guide conduits between the headrest and the treatment couch in a protected manner.
- motor drives of the Z-adjustment of the headrest are preferred in this invention.
- these are controlled in a manner adapted to adjusting movements of the treatment couch, so that esp.
- An automatic tilt compensation of the headrest can be done when the treatment table or its deck plate is tilted. This tilting movement of the deck plate can u. a. occur because a vertical Z-adjustment of the deck plate by a pivoting movement thereof takes place and the associated pivot axis is remote from the headrest.
- the automatic tilt compensation then makes it possible to keep constant the angular orientation of the headrest, i. for example, a consistently horizontal position of the headrest. This is particularly advantageous in treatments of the patient's head.
- the headrest further comprises an X-adjustment relative to the deck plate, and preferably also by a pivoting movement about a now lying parallel to the Z-direction of rotation axis.
- This adjustment is preferably motorized.
- the X-adjustment can be done in a (mechanically or motorized) adapted to an X-adjustment of the deck plate manner, in order to pivot-X adjustments of the deck plate a corresponding angle compensation in the headrest to obtain. Then namely the patient's head can be moved in the X direction, without causing an angle error occurs in the region of lying on the headrest patient head.
- this option is omitted, the angle errors that occur are not so great that this would lead to a problem in all applications.
- a headrest according to the invention mounted in a modular manner on the treatment couch is adjusted, a risk of jamming can occur.
- the invention provides in this case to leave sufficient distances, so that esp.
- the treatment personnel is not subject to any risk of jamming.
- since an at least substantially continuous lying surface is to be created for the patient it is preferable to extend an already favorable cushion on the headrest beyond its fixed parts, so that such safety gaps are covered.
- the Z-adjustment and the X-adjustment take place via the described pivoting movements.
- the Y-adjustment so the adjustment in the longitudinal direction, continue to make in a conventional manner via a linear guide. Since the Y-adjustment is not carried out gravitationally parallel, it may be sufficient here to use a single linear drive, such as a spindle drive, and to store the deck plate, moreover, displaceably in the Y direction.
- the Y-displacement move from the fixed base, and further that the X-displacement be the Z-displacement mechanism "entrains", so to speak, between the Y-adjustment and the Z-adjustment is interposed.
- the X-adjustment of gravity influences remain free and can limit the Z-adjustment to the movement of relatively smaller components of the entire treatment couch.
- the treatment couch may comprise a support leg, which is entrained in the X-adjustment and is mounted on a with respect to the X-adjustment rotary axis remote part of the treatment table, preferably in the vicinity of the shoulder or head region of the patient.
- 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 the treatment of the human body, but can also be used in treatment beds for animals. A particularly preferred area is the laser surgery on the human eye, in which the treated eye can be brought into the correct position for the laser surgery by the treatment couch according to the invention.
- the invention also relates to a method for storing a patient using the described treatment couch.
- the foregoing and following description of the treatment couch in its device details is to be understood as a disclosure of said method.
- FIG. 1 shows the side view of a treatment table according to the invention, with some interesting technical details are shown, which would not be visible from the outside when the housing is closed.
- FIG. 1 However, for clarity, no knee brace.
- the FIGS. 13 to 22 describe the structure of the deck plate with a knee brace in detail.
- the deck plate 1 is mounted in a manner to be explained in more detail on a base 4, which rests on Verstellffure 5 on a floor 6.
- a linear drive with an electric motor 7 and a driven by this spindle lifting rod 8 is fixedly mounted.
- the spindle lifting rod 8 is mounted on a bracket 9, 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 about running on a rail 11 linear guides 12 in FIG. 1 horizontal direction and thus slidably mounted in the longitudinal direction of the deck plate 1. This direction thus corresponds to the Y direction.
- the first intermediate plate 10 carries at about 17% - 18% of the longitudinal extent on the side of the foot (drawing not to scale) a bearing 13 in FIG. 1 vertical axis of rotation.
- a second intermediate plate 14 is rotatably supported relative to the first intermediate plate 10 about the vertical axis through the bearing 13.
- the second intermediate plate 14 is supported on a running surface 16 of the first intermediate plate 10 via a roller designated 15 and on the other hand connected to a driver 17 which is driven by a toothed belt described in more detail below.
- the timing belt runs in a FIG. 1 with 18 designated housing.
- the second intermediate plate 14 can be pivoted about the vertical axis passing through the bearing 13, which in the Y-direction spaced from the bearing 13 areas, ie in particular in the headrest 3, an adjustment in a direction perpendicular to the plane, namely the X-direction, corresponds.
- a pivot bearing 19 is provided, on which the deck plate 1 is articulated.
- the deck plate 1 is pivotally connected to a Spindelhubstange 20 which is linearly driven by an electric motor 21, which in turn is hinged to a mounting platform of the second intermediate plate 14.
- FIG. 2 shows the side view according to FIG. 1 with some deviations regarding the adjustment positions.
- the comparison of FIG. 1 and 2 shows, on the one hand, that, by extending the spindle lifting rod 20 out of the electric motor 21, the lying plate 1 can be pivoted about the axis of rotation 19 and thus raised in the head region in the vertical direction, that is to say in the Z direction.
- FIG. 3 shows a plan view of the treatment couch from the FIG. 1 and 2
- the mechanism for driving the driver 17 is shown in more detail.
- An electric motor 22 with lying in the Z direction of rotation axis drives a toothed belt 23, which is guided over four pulleys 24 and is secured to the driver 17.
- a rotation of the output shaft of the electric motor 22 thus moves the driver 17 in the X direction and thus moves the second intermediate plate 14 relative to the first intermediate plate 10 in the X direction.
- FIG. 4 illustrated wherein in solid lines one with the head end according to FIG 4 down adjustment in the X direction and in dashed lines a taken in the opposite direction X-adjustment is located.
- the reference numbers omitted.
- the rotation takes place about the axis through the bearing 13.
- FIG. 1 and FIG. 2 show further that in the Z direction under the levers 25, a further Spindelhubstange 26 is provided with an electric motor 27.
- the electric motor 27 is hinged to the headrest 3.
- the spindle lifting rod 26 is hinged to the deck plate 1.
- FIG. 1 and 2 shows that by retracting and extending the screw jack 26 in and out of the motor 27, a tilting movement of the headrest 3 about the hinge axis of the lever 25 on the deck plate 1, with which in particular an automatic tilt compensation in Z-adjustment of the deck plate 1 can accomplish , This tilt compensation is in FIG. 2 clearly.
- the headrest 3 can of course be tilted in other ways, if desired.
- the automatic tilt compensation is done by appropriate tuning of 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 a sectional view seen in the X direction.
- the headrest 3 has a holding plate 28, the exact structure of which is even clearer from the following figures and which can be fastened by fastening screws 29 on the treatment couch itself.
- the holding plate 28 is already in the Figure 1 - 4 symbolically represented, 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. They also hold in the holding plate 28 a hinge box 31, in which the already with reference to Figure 1 - 4 mentioned and shown there rack 26 is articulated.
- the actual head shell 32 of the headrest 3 is hinged to the support plate 28 via two joint boxes lying above or below the plane of the drawing with corresponding rocker arms.
- This head shell 32 consists of an anatomically shaped upper part 33 and an attached housing part 34, in which the already mentioned rack 26 protrudes.
- the housing part 34 is arranged below the plane of the electric motor 27, which is already in FIG. 1 is shown with an in FIG. 5 well recognizable output pinion installed.
- a guide 35 is provided which holds and guides the rack 26, but in which it is displaceable. The guide 35 can be pivoted about the axis of the output pinion of the electric motor 27 and thus follow in the movement of the headrest 3 a pivotal movement of the rack 26 about the articulated attachment in the hinge box 31.
- the headrest 33 consists essentially of a soft foam pad 36, which is attached via a hook and loop fastener 37 to an upper plate of the housing part 34. To facilitate insertion of this pad 36, not shown centering pins may additionally be provided here.
- FIG. 5 shows in the horizontal position of the headrest 33 slightly spaced from the holding plate 28, so in the direction of the holding plate 28 facing direction does not protrude 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, which is surmounted by the pad 36. A risk of jamming is not given because this slot is sized so large that operators can not easily pinch their fingers. Furthermore, the pad 36, which can approach more closely to the holding plate 28 in a downward movement than in FIG. 5 drawn, dodge upwards. This follows, on the one hand, from a certain deformability and, on the other hand, is an advantage of the Velcro fastener 37.
- FIG. 6 shows an alternative embodiment FIG. 5 in the same way on a treatment couch according to the Figure 1 - 4 can be appropriate.
- the following is merely compared to the differences FIG. 5 received.
- a centering pin 38 is shown, the pad 36 on the upper plate of the housing part 34 of the headrest 32 holds.
- 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 with a the output gear 27 from FIG. 5 corresponding pinion for driving the rack 26th
- the hand crank 39 has a fold-out pin for ease of cranking, indicated at 42. It can be seen that the manual drive in the same way is part of the headrest 3, as for the electric motor 27 with the associated drive parts in FIG. 5 applies. Otherwise there are no fundamental differences FIG. 5 ,
- FIG. 7 illustrates the headrest 3 off FIG. 6 in an exploded view. It can be seen that the pad 36 has a somewhat semicircular shape and the housing part 34 of the headrest 32 is adapted to this semi-circular shape and holds the pad 36 from the 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 this. Projecting supernatant.
- the hinge box 31 shows FIG. 7 two other Gelerikhimsten, which are designated 43 and are held by screws 44. These joint boxes 43 carry hinge pins, which are attached to the housing part 34 of the headrest 32 and on the other hand inserted into the recognizable receiving holes of the holding plate 28 and screwed with the screws 44.
- the fastening screws 29 and 44 also serve for fastening the retaining plate 28 to the rest of the treatment couch in a manner not shown in detail. They are screwed through a plate of the treatment couch through the support plate 28 with the hinge boxes 31 and 43.
- FIG. 7 in perspective, the guide 35 for the rack 26 and the worm gear 40, 41 from FIG. 6 ,
- the rack 26 is designed as a hollow tube.
- electrical lines can be laid in the rack, such as when instead of the manual drive 39 - 42, an electric motor drive 27 is used.
- FIG. 8 shows an analog representation FIG. 7 , but to the embodiment of FIG. 5 , Furthermore, in the illustration FIG. 8 for illustration, the pad 36 omitted, the FIG. 7 shows. Incidentally, the explanatory notes to the FIGS. 5 to 7 directed.
- FIG. 9 and 10 show a side view of the headrest 3 from FIG. 6 and 7 with a lower and an upper adjustment position and a perspective view of the headrest 3 for a better understanding of FIG. 7 ,
- no reference numbers are drawn in order to improve the pictorial representation.
- FIG. 9 In particular, it can be seen that an adjustment with the manual drive 39 - 42 causes the headrest 32 to move upwards relative to the holding plate 28 and thereby to be supported by the rack 26 and the hinge box 31. The same applies vice versa for an adjustment down.
- This can be done in the context of a motorized embodiment adapted to a Z-adjustment of the deck plate 2 of the treatment couch to ensure a constant, for example, horizontal holding the patient's head. This is esp.
- the treatment table according to the following explanations of importance.
- the rack 26 or, more generally, the length adjustment element of the drive is arranged below the hinges forming the pivot axis. This is advantageous because then smaller changes in length due to a headrest adjustment on the level of the patient's head (in the Y direction) occur and the drive is thus better accessible from below for operation or for removal and installation.
- FIG. 11 shows a schematic plan view of another embodiment to illustrate the optional feature of an X-adjustment of the headrest 3.

- the holding plate 28 can be adjusted relative to the deck plate 1 about the axis of rotation 47, so that angular errors due to X-adjustments of the deck plate 1 can be compensated for the rotation axis 13.
- the Y errors occurring in this example - the axis of rotation 47 is not centered - can in turn be taken into account by an automatic consideration in the Y-adjustment of the deck plate 1, if desired.
- the X-adjustability of the headrest 3 can of course be beneficial for other reasons.
- FIG. 12 again shows another optional embodiment in which the X-adjustable part of the treatment couch is intercepted via an adjustable support leg 48 on the floor.

- the head of this device Above the headrest 3, the head of this device is mounted and directs a Z-directional laser beam into the eye, which must be brought to the treatment couch in the appropriate position.
- X-adjustment allows switching between the two eyes of the patient.

- the X-adjustment can also be used to facilitate the patient's entry.
- FIG. 13 shows the deck plate 1 of the mattress 2 from the previous figures in more detail, the headrest 3 and the other parts of the treatment table for the sake of clarity are omitted.

Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Behandlungsliege zur Lagerung von Patienten, und zwar konkret auf eine Behandlungsliege mit einer Kniestütze zur bequemeren Lagerung der Beine des Patienten.The present invention relates to a treatment table for the storage of patients, specifically on a treatment table with a knee support for more comfortable storage of the legs of the patient.
Behandlungsliegen zur Lagerung von Patienten weisen grundsätzlich eine Liegeplatte für den Patienten und eine die Liegeplatte auf einem Boden, etwa in einem Behandlungsraum, abstützende Basis auf. Die Liegeplatte kann natürlich gepolstert sein, es muss sich also nicht notwendigerweise um eine starre Platte im engeren Sinn handeln. Die Liegeplatte kann ferner auch mehrteilig sein, etwa aus verschiedenen plattenartigen Elementen zusammengesetzt.Treatment couches for patient storage basically have a couch plate for the patient and a base supporting the couch panel on a floor, such as in a treatment room. Of course, the deck plate can be upholstered, so it does not necessarily have to be a rigid plate in the narrower sense. The deck plate may also be multi-part, composed of various plate-like elements.
Bei den Behandlungsliegen für zahnärztliche Behandlungen sind ferner Kniestützen bekannt. Sie weisen einen Oberschenkelabschnitt zur Stützung der Oberschenkel des Patienten auf, der gegenüber einem Oberkörperabschnitt der Liege angewinkelt ist. Der Patient ist also bei der zahnärztlichen Behandlung nicht dazu gezwungen, flach ausgestreckt zu liegen, sondern kann eine bequemere Haltung einnehmen, in der seine Beine durch eine Kniestütze so hoch gelagert sind, dass die Oberschenkel gegenüber dem Oberkörper etwas angewinkelt sind. Mit dem Begriff "Kniestütze" ist hier also eine Ausformung der Liegeplatte in solcher Weise gemeint, dass die Knie etwas "angehoben" gelagert sind.Knee braces are also known in the dental treatment tables. They have a thigh portion for supporting the thighs of the patient, which is angled relative to a torso portion of the couch. The patient is therefore not forced to lie flat while lying in the dental treatment, but can adopt a more comfortable posture in which his legs are supported by a knee brace so high that the thighs are slightly angled relative to the torso. By the term "knee brace" is here thus meant a shaping of the platform in such a way that the knees are slightly "raised" stored.

Der Erfindung liegt das technische Problem zugrunde, eine Behandlungsliege für die Lagerung von Patienten mit einer verbesserten Kniestütze anzugeben.The invention is based on the technical problem of specifying a treatment couch for the storage of patients with an improved knee brace.
Die Erfindung richtet sich auf eine Behandlungsliege zur Lagerung eines Patienten mit einer Liegeplatte für den Patienten, die einen Oberkörperbereich zur Lagerung des Oberkörpers des Patienten aufweist, und einer Basis zur Abstützung der Liegeplatte auf einem Boden, wobei die Liegeplatte eine Kniestütze aufweist, die einen gegenüber dem Oberkörperbereich der Liegeplatte angewinkelten Oberschenkelabschnitt aufweist, dadurch gekennzeichnet, dass die Kniestütze relativ zu dem Oberkörperbereich in der Längsrichtung der Behandlungsliege verschiebbar ist, sodass der Abstand zwischen einem auf dem Oberkörperabschnitt festgelegten Punkt und dem hüftseitigen Beginn des Oberschenkelabschnitts, an der der Oberschenkelabschnitt dem Oberkörperbereich am nächsten kommt, verändert werden kann.The invention is directed to a treatment couch for supporting a patient with a patient support plate having a torso portion for supporting the upper body of the patient and a base for supporting the support plate on a floor, the bed plate having a knee brace facing one characterized in that the knee brace is slidable relative to the upper body region in the longitudinal direction of the treatment couch, so that the distance between a fixed on the upper body portion point and the upper part of the abdominal area the hip-side beginning of the thigh portion at which the thigh portion comes closest to the upper body area, can be changed.
Daneben richtet sich die Erfindung auch auf ein medizinisches Gerät mit einer solchen Behandlungsliege und auf ein entsprechendes Verfahren zur Lagerung eines Patienten.In addition, the invention is also directed to a medical device with such a treatment table and to a corresponding method for storage of a patient.
Bevorzugte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben. Die nachfolgende Offenbarung bezieht sich sowohl auf den Vorrichtungsaspekt als auch auf den Verfahrensaspekt der Erfindung, ohne dass hierzwischen noch explizit unterschieden wird.Preferred embodiments of the invention are specified in the dependent claims. The following disclosure relates both to the device aspect and to the method aspect of the invention, without any explicit distinction between them.
Die erfindungsgemäße Behandlungsliege weist eine Kniestütze mit einem gegenüber dem Oberkörperbereich der Liegeplatte angewinkelten Oberschenkelabschnitt auf. Erfindungsgemäß ist diese Kniestütze in der Längsrichtung der Behandlungsliege, also in der vom Fuß zum Kopf des Patienten bzw. umgekehrt weisenden Richtung, relativ zu dem Oberkörperbereich verschiebbar. Diese Verstellbarkeit ist begrifflich zu unterscheiden von der von zahnärztlichen Behandlungsliegen bereits bekannten Verkippbarkeit des Oberkörperbereichs einer Behandlungsliege gegenüber dem Oberschenkelabschnitt der Kniestütze. Bei dieser Erfindung geht es vielmehr zunächst um eine zumindest im Wesentlichen translatorische Verschiebung, bei der also der Abstand zwischen einem auf dem Oberkörperabschnitt festgelegten Punkt, etwa dem oberen Ende des Oberkörperabschnitts, und dem hüftseitigen Beginn des Oberschenkelabschnitts, an der der Oberschenkelabschnitt dem Oberkörperbereich am nächsten kommt, verändert wird.The treatment couch according to the invention has a knee brace with a thigh portion angled relative to the upper body area of the bed plate. According to the invention, this knee brace is displaceable relative to the upper body region in the longitudinal direction of the treatment couch, ie in the direction pointing from the foot to the head of the patient or vice versa. This adjustability is conceptually distinguishable from the already known from dental treatment tables Verkippbarkeit the upper body portion of a treatment couch against the thigh portion of the knee brace. Rather, this invention is initially concerned with an at least substantially translatory displacement, ie with the distance between a point fixed on the upper body section, for example the upper end of the upper body section, and the hip-side beginning of the thigh section, at which the upper leg section is closest to the upper body region comes, is changed.
In dieser Weise kann die Behandlungsliege besonders günstig auf unterschiedliche Körpergrößen der Patienten eingestellt werden. Bei medizinischen Behandlungen von Körperteilen im Bereich des Oberkörpers, Kopfes oder der oberen Gliedmaßen kann insbesondere vermieden werden, dass die Lage der zu behandelnden Stelle bei unterschiedlich großen Patienten sehr unterschiedlich ist. Durch eine Anpassung der Längsposition der Kniestütze kann vielmehr beispielsweise dafür gesorgt werden, dass der Kopf des Patienten im Wesentlichen auf der gleichen Längsposition liegt, wenn der Kopf zu untersuchen oder zu behandeln ist.In this way, the treatment table can be set particularly favorable to different body sizes of the patient. In medical treatments of body parts in the area of the upper body, head or upper limbs, it is possible, in particular, to prevent the location of the area to be treated from becoming very different for patients of different sizes. By adjusting the longitudinal position of the knee brace, for example, it can be ensured, for example, that the head of the patient lies substantially at the same longitudinal position when the head is to be examined or treated.
Insbesondere gehen die Möglichkeiten der Erfindung damit über eine in Längsrichtung verstellbare separate Kopfstütze hinaus, weil der Verstellbereich einer solchen Kopfstütze naturgemäß beschränkt ist, wenn nicht bei großen Patienten Lücken zwischen Kopfstütze und Oberkörperbereich der Liegeplatte in Kauf genommen werden sollen.In particular, the possibilities of the invention thus go beyond a longitudinally adjustable separate headrest, because the adjustment range of such a headrest is naturally limited, if not to be taken in large patients gaps between the headrest and upper body area of the platform.
Bei einer bevorzugten Ausführungsform der Erfindung ist die Kniestütze zusätzlich "höhenverstellbar", d. h. dass das knieseitige Ende des Oberschenkelabschnitts angehoben werden kann. Dies kann in einer translatorischen Weise erfolgen, vorzugsweise ist jedoch der Oberschenkelabschnitt relativ zu dem Oberkörperbereich der Liegeplatte verkippbar.In a preferred embodiment of the invention, the knee brace is additionally "height adjustable", d. H. that the knee-side end of the thigh section can be raised. This can be done in a translatory manner, but preferably the thigh section is tiltable relative to the upper body region of the deck plate.
Vorzugsweise weist die Kniestütze neben dem Oberschenkelabschnitt auch einen Unterschenkelabschnitt auf, der gegenüber dem Oberschenkelabschnitt so angewinkelt ist, dass sich von der Seite des Knies des Patienten her gesehen eine konvexe Wölbung oder ein konvexer Knick ergibt. Bei einer bevorzugten Ausführungsform ist der Unterschenkelabschnitt so aufgebaut, dass er bei dem oben erwähnten Anheben des khieseitigen Endes des Oberschenkelabschnitts mit seinem knieseitigen Ende mitgenommen wird und dabei aber das fußseitige Ende des Unterschenkelabschnitts näherungsweise auf gleicher Höhe, insbesondere näherungsweise im Bereich der Flucht des Oberkörperbereichs der Liegeplatte, bleibt. Damit wird die konvexe Wölbung bzw. der konvexe Knick in der Höhe verstellt, ohne dass die Fußposition des Patienten damit in der Höhe stark beeinflusst wird. Zur Illustration wird auf das Ausführungsbeispiel verwiesen.Preferably, in addition to the thigh portion, the knee brace also has a lower leg portion which is angled relative to the thigh portion so as to provide a convex curvature or a convex curvature when viewed from the side of the knee of the patient. In a preferred embodiment, the lower leg portion is constructed so that it is taken in the above-mentioned lifting of the khieseitigen end of the thigh portion with its knee-side end and thereby the foot-side end of the lower leg portion approximately at the same height, in particular approximately in the area of escape of the upper body portion of Liegeplatte, remains. This adjusts the height of the convex curvature or the convex curvature, without affecting the height of the patient's foot position. For the sake of illustration, reference is made to the exemplary embodiment.
Eine günstige Möglichkeit zur Implementierung der beschriebenen Verstellbarkeit der Kniestütze besteht darin, dass der Oberschenkelabschnitt an seinem hüftseitigen Ende an einem anderen Bauteil, insbesondere einer Lagerplatte, angelenkt ist, das seinerseits in Längsrichtung verschiebbar ist. Gleichzeitig ist das knieseitige Ende des Oberschenkelabschnitts über einen Hebel an einem weiteren, also zweiten Bauteil angelenkt, das unabhängig von dem ersten Bauteil in Längsrichtung verschiebbar ist. Auch bei dem zweiten Bauteil kann es sich um eine Lagerplatte handeln. Der Hebel ist also einerseits an der zweiten Lagerplatte und andererseits an dem knieseitigen Ende des Oberschenkelabschnitts angelenkt. Eine gemeinsame Längsverschiebung der beiden Bauteile verschiebt damit den Oberschenkelabschnitt in Längsrichtung und nimmt, wenn der Unterschenkelabschnitt mit seinem fußseitigen Ende von der zweiten Lagerplatte mitgenommen wird, die gesamte Kniestütze mit. Eine Relativbewegung zwischen den beiden Lagerplatten verändert aber den Abstand zwischen der lagerplattenseitigen Gelenkachse des Hebels und der Gelenkachse zwischen dem hüftseitigen Ende des Oberschenkelabschnitts und der ersten Lagerplatte, so dass sich der Hebel aufstellt oder absenkt und damit die Anwinkelung des Oberschenkelabschnitts verändert wird. Zur Illustration wird wieder auf das Ausführungsbeispiel verwiesen.A favorable possibility for implementing the described adjustability of the knee brace is that the thigh portion is hinged at its hip-side end to another component, in particular a bearing plate, which in turn is displaceable in the longitudinal direction. At the same time, the knee-side end of the thigh section is articulated via a lever to a further, ie second component, which is displaceable independently of the first component in the longitudinal direction. Also, the second component may be a bearing plate. The lever is thus hinged on the one hand to the second bearing plate and on the other hand to the knee-side end of the thigh portion. A common longitudinal displacement the two components thus displaces the thigh portion in the longitudinal direction and, when the lower leg portion is taken with its foot-side end of the second bearing plate, with the entire knee brace. However, a relative movement between the two bearing plates changes the distance between the bearing plate-side hinge axis of the lever and the hinge axis between the hip-side end of the thigh section and the first bearing plate, so that the lever is raised or lowered and thus the Anwinkelung the thigh section is changed. For purposes of illustration, reference is again made to the exemplary embodiment.
Im Rahmen der Erfindung ist es grundsätzlich bevorzugt, die erfindungsgemäße Verschiebbarkeit in Längsrichtung über Längsschienen zu implementieren. In Zusammenhang mit der vorstehend erläuterten Ausführungsform können dabei die erste und die zweite Lagerplatte oder allgemeiner gesprochen das erste und das zweite Bauteil jeweils über Längsschienen verschiebbar sein und bei einer besonders bevorzugten Ausführungsform über mit den Längsschienen integrierte Spindeistangen antreibbar und damit verstellbar sein. Im Prinzip würde eine einzige Längsschiene ausreichen, bevorzugt sind jedoch eine Mehrzahl Längsschienen, insbesondere zwei Längsschienen jeweils im Bereich des seitlichen Randes der Liegeplatte.In the context of the invention, it is basically preferable to implement the displaceability according to the invention in the longitudinal direction via longitudinal rails. In connection with the embodiment explained above, the first and the second bearing plate or, more generally speaking, the first and the second component can each be displaceable via longitudinal rails and, in a particularly preferred embodiment, can be driven and thus adjustable by means of locking bars integrated with the longitudinal rails. In principle, a single longitudinal rail would be sufficient, but a plurality of longitudinal rails, in particular two longitudinal rails are preferred, in each case in the region of the lateral edge of the deck plate.
Der integrierte Spindelantrieb kann so ausgestaltet sein, dass einerseits Führungen der verschiebbaren Bauteile über glatte Bereiche der Führungsschienen rutschen können, während andererseits zumindest ein mit einem Innengewinde versehenes Führungselement, das also als Mutter dient, auf einem Gewindeabschnitt an der jeweiligen Führungsstange angetrieben ist. Insbesondere kann dabei eine von zwei seitlich angebrachten Führungsstangen jeweils für den Antrieb eines der verschiebbaren Bauteile vorgesehen sein. Zugunsten einer klemmfreien guten Führung sind vorzugsweise zumindest zwei über die mit der Mutter versehene Führung hinausgehende nicht angetriebene Führungen pro verschiebbarem Bauteil vorgesehen, wovon zumindest eine an der jeweils anderen Führungsschiene läuft. Auch dies ist im Ausführungsbeispiel veranschaulicht.The integrated spindle drive can be configured such that, on the one hand, guides of the displaceable components can slide over smooth areas of the guide rails, while, on the other hand, at least one guide element provided with an internal thread, which serves as a nut, is driven on a threaded section on the respective guide rod. In particular, one of two laterally mounted guide rods can be provided in each case for driving one of the displaceable components. In favor of a jam-free good guidance, at least two non-driven guides per displaceable component which extend beyond the guide provided with the nut are preferably provided, of which at least one runs on the respective other guide rail. This too is illustrated in the exemplary embodiment.
Vorzugsweise ist die erfindungsgemäße Behandlungsliege nicht nur hinsichtlich der beschriebenen Verstellmöglichkeiten der Kniestütze verstellbar, sondern auch in anderer Hinsicht. Insbesondere soll die Liegeplatte vorzugsweise gegenüber der Basis entlang zumindest zwei zueinander im Wesentlichen senkrechten Richtungen verstellbar sein, um die Lageposition des Patienten auch im Übrigen einstellen zu können, beispielsweise eine Feinpositionierung des Kopfes relativ zu einem medizinisch technischen Gerät vornehmen zu können. Dabei kann die Liegeplatte bei der Verstellung um eine senkrecht zu ihrer Längsrichtung liegende Drehachse schwenkbar sein.Preferably, the treatment couch according to the invention is adjustable not only in terms of the described adjustment of the knee brace, but also in others Respect. In particular, the deck plate should preferably be adjustable relative to the base along at least two mutually substantially perpendicular directions in order to adjust the position of the patient, moreover, for example, to be able to make a fine positioning of the head relative to a medical technical device. In this case, the bed plate may be pivotable in the adjustment about a rotational axis lying perpendicular to its longitudinal direction.
Diese Ausführungsform zeichnet sich also dadurch aus, dass zumindest eine der genannten Verstellmöglichkeiten durch einen Schwenkbewegungsmechanismus mit einer Drehachse gelöst sein soll. Dabei soll die Drehachse senkrecht zu der Längsrichtung, der sog. "Y-Richtung", liegen, so dass sich bei einer Schwenkbewegung um eine zur einer vertikalen "Z-Achse" parallele Drehachse eine horizontale "X-Verstellung" und bei einer zu der horizontalen "X-Richtung" parallelen Drehachse eine "Z-Verstellung" ergibt.This embodiment is thus characterized by the fact that at least one of said adjustment options should be solved by a pivoting movement mechanism with a rotation axis. In this case, the axis of rotation is perpendicular to the longitudinal direction, the so-called. "Y-direction", so that in a pivoting movement about a vertical "Z-axis" parallel axis of rotation a horizontal "X-adjustment" and at one to the horizontal "X-direction" parallel axis of rotation results in a "Z-adjustment".
Es hat sich nämlich gezeigt, dass die konventionellen Linearführungen bei zwei, insb. bei erfindungsgemäß bevorzugten drei Verstetllachsen zu einem erheblichen technischen Aufwand und damit relativ teuren Konstruktionen führen. I. d. R. werden für die X- und die Z-Verstellrichtungen jeweils mehrere Antriebe eingesetzt. Demgegenüber lassen sich die X-Verstellung und die Z-Verstellung relativ leicht durch eine Schwenkbewegung um die genannten Achsen bewerkstelligen. Dabei können insbesondere Antriebe eingespart werden, also im Fall einer Handverstellung entsprechende Antriebe mit Handbetätigung oder anderenfalls Motorantriebe. Es ist sogar möglich, wenn auch nicht unbedingt notwendig, nur einen einzigen Antrieb für die Schwenkbewegung um eine Drehachse vorzusehen. Bei der Erfindung handelt es sich im Übrigen bzgl. aller Drehachsen jeweils vorzugsweise um motorische Antriebe, jedoch sind auch Behandlungsliegen mit handangetriebenen Verstellmöglichkeiten oder solche mit teils motorischen und teils handangetriebenen Verstellmöglichkeiten inbegriffen.It has been shown that the conventional linear guides in two, esp. In accordance with the invention preferred three Verstetllachsen lead to a considerable technical effort and thus relatively expensive constructions. I. d. R. are used for the X and the Z-adjustment directions each have multiple drives. In contrast, the X-adjustment and the Z-adjustment can be accomplished relatively easily by a pivoting movement about said axes. In particular, drives can be saved, ie in the case of a manual adjustment corresponding drives with manual operation or otherwise motor drives. It is even possible, though not absolutely necessary, to provide only a single drive for the pivotal movement about a rotation axis. In the case of the invention, by the way, with respect to all axes of rotation, preferably motor drives are preferably included, but treatment couches with hand-operated adjustment possibilities or those with partly motorized and partly manually operated adjustment options are also included.
Vorzugsweise sind sowohl die X-Verstellung als auch die Z-Verstellung über einen Schwenkbewegungsmechanismus gelöst, jedoch werden wesentliche Vorteile der Erfindung schon dann erzielt, wenn nur eine der beiden Verstellmöglichkeiten in dieser Weise ausgeführt ist.Preferably, both the X-adjustment and the Z-adjustment via a pivoting movement mechanism are solved, however, significant advantages of the invention are already achieved when only one of the two adjustment is carried out in this way.
Besonders bewährt hat sich eine Positionierung der Drehachse für die Z-Verstellung (also der X-parallelen Drehachse) im Bereich des Fußendes der Liegeplatte und ferner eine Positionierung der Drehachse für die X-Verstellung (also der Z-parallelen Drehachse) von der Liegenmitte aus auf der Seite des Fußendes, und zwar in Bezug auf die Y-Längsrichtung. Damit werden bei der Verstellung bereits in der Körpermitte und erst recht am Kopfende infolge einer Schwenkbewegung um die Drehachse erhebliche Hubhöhen erreicht. Konkret bedeutet dies, dass die X-parallele Schwenkachse in Bezug auf die Längserstreckung der Liegeplatte vom Fußende aus gesehen etwa innerhalb von 10% der Längserstreckung liegt, wobei die Bezugsgröße 100% der Gesamtlänge der Liegeplatte ohne die im Folgenden noch näher erläuterte optionale Kopfstütze bedeutet. In gleichem Sinn liegt die Z-parallele Schwenkachse vorzugsweise innerhalb 30% der Längserstreckung vom Fußende aus gesehen, besonders bevorzugter Weise innerhalb 25% und im günstigsten Fall innerhalb 20%.A positioning of the axis of rotation for the Z-adjustment (ie the X-parallel axis of rotation) in the area of the foot end of the deck plate and also a positioning of the axis of rotation for the X-adjustment (ie the Z-parallel axis of rotation) from the middle of the bed has proven particularly useful on the side of the foot end, with respect to the Y longitudinal direction. Thus, in the adjustment already in the middle of the body and even more at the head end as a result of pivotal movement about the axis of rotation reaches considerable lifting heights. Specifically, this means that the X-parallel pivot axis is approximately within 10% of the longitudinal extent with respect to the longitudinal extent of the deck plate from the foot end, the reference amounting to 100% of the total length of the deck plate without the optional optional headrest. In the same sense, the Z-parallel pivot axis is preferably within 30% of the longitudinal extent seen from the foot end, more preferably within 25% and in the best case within 20%.
Der motorische Verstellantrieb für die Z-Verstellung kann bei einer bevorzugten Ausgestaltung ein Motor, etwa ein Elektromotor, mit einem an einer Abtriebswelle vorgesehenen Kopplungsrad und einem von dem Kopplungsrad angetriebenen Kopplungsband sein. Bei dem Kopplungsrad und Kopplungsband kann es sich beispielsweise um eine Zahnrad/Zahnriemen- oder Zahnrad/Kettenkombination handeln. Das Kopplungsband trägt einen Mitnehmer, der entweder den verstellbaren Teil der Behandlungsliege mitnimmt oder mit dem während der Z-Verstellung nicht bewegten Teil der Behandlungsliege gekoppelt ist. Im erstgenannten Fall ist der Motor in Bezug auf den während der Z-Verstellung festen Teil der Behandlungsliege ortsfest, im zweitgenannten Fall gegenüber dem von der Z-Verstellung erfassten Teil der Behandlungsliege ortsfest. In dieser Weise kann die bogenförmige Verstellbewegung durch einen einfachen rotatorischen Antrieb realisiert werden. Zur Veranschaulichung wird auf das Ausführungsbeispiel verwiesen.In a preferred embodiment, the motor adjustment drive for the Z adjustment can be a motor, for example an electric motor, with a coupling wheel provided on an output shaft and a coupling belt driven by the coupling wheel. The coupling wheel and coupling belt may be, for example, a gear / toothed belt or gear / chain combination. The coupling band carries a driver, which either entrains the adjustable part of the treatment couch or is coupled to the part of the treatment couch which is not moved during the Z adjustment. In the former case, the motor is stationary with respect to the fixed during the Z-adjustment of the treatment couch, in the second-mentioned case relative to the detected by the Z-adjustment of the treatment couch stationary. In this way, the arcuate adjustment can be realized by a simple rotary drive. For the sake of illustration, reference is made to the exemplary embodiment.
Eine bevorzugte Ausgestaltung des X-Verstellantriebs kann ein an sich konventioneller Lineartrieb, etwa ein Spindelhubtrieb oder Zahnstangentrieb, sein, der an seinen beiden Enden, d. h. an einem bzgl. der Linearbewegung ortsfesten und einem durch die Linearbewegung bewegten Ende, gelenkig montiert ist. Durch die gelenkige Montage kann der an sich linear arbeitende Lineartrieb bei der eigentlich bogenförmigen Schwenkbewegung um die erfindungsgemäße Drehachse verwendet werden.A preferred embodiment of the X-adjustment can be a per se conventional linear drive, such as a Spindelhubtrieb or rack and pinion, which is articulated at its two ends, ie at a respect. The linear motion and an end moved by the linear movement end. Due to the articulated mounting of the linear linear actuator can be used in the actually arcuate pivoting movement about the rotation axis according to the invention.
Vorzugsweise weist die Behandlungsliege eine Kopfstütze zur Lagerung des Patientenkopfes auf, die gegenüber der Liegeplatte verstellbar ist. Diese Verstellbarkeit kann zusätzlich zu der bereits beschriebenen Verstellbarkeit der Liegeplatte bei Behandlungen am Kopf von Interesse sein. Im Rahmen dieser Erfindung interessiert jedoch besonders eine Kopfstütze, welche in einer im Wesentlichen vertikalen Z-Richtung gegenüber der Liegeplatte verstellbar ist, bei der ein Antrieb für die Z-Verstellung der Kopfstütze in der Kopfstütze eingebaut ist und die Kopfstütze zusammen mit dem Antrieb als Modul von der Behandlungsliege abnehmbar ist.Preferably, the treatment table on a headrest for supporting the patient's head, which is adjustable relative to the deck plate. This adjustability may be of interest in addition to the already described adjustability of the platform for treatments on the head. However, in the context of this invention is particularly interested in a headrest, which is adjustable in a substantially vertical Z-direction relative to the deck plate, in which a drive for the Z-adjustment of the headrest is installed in the headrest and the headrest together with the drive as a module is detachable from the treatment couch.
Der Antrieb dieser Kopfstütze, ob es sich nun um einen Handantrieb, etwa über eine Handkurbel oder ein Verstellrad, oder um einen Motor, insb. Elektromotor, handelt, soll Teil der Kopfstütze sein. Dies bedeutet, dass die Kopfstütze als eigenständige Baueinheit an der Behandlungsliege montiert und abnehmbar ist, ohne dass dabei der Antrieb selbst von der Kopfstütze getrennt werden müsste. Der Antrieb soll also allenfalls über Signalleitungen oder Versorgungsleitungen mit der übrigen Behandlungsliege gekoppelt sein, etwa weil er gemeinsam mit dortigen Motoren versorgt wird oder von einer gemeinsamen Steuerung angesteuert wird. Die Verbindung zwischen der Kopfstütze und der Behandlungsliege beschränkt sich also auf statische lösbare Befestigungen und Leitungen.The drive of this headrest, whether it is a manual drive, such as a hand crank or an adjustment, or a motor, esp. Electric motor, is to be part of the headrest. This means that the headrest is mounted as an independent unit to the treatment table and removable without the drive itself would have to be separated from the headrest. The drive should therefore at most be coupled via signal lines or supply lines to the other treatment couch, for example because it is supplied together with local motors or is controlled by a common control. The connection between the headrest and the treatment bed is therefore limited to static releasable fasteners and lines.
Der Stand der Technik hat stattdessen den Antrieb in der Behandlungsliege verbaut, und zwar beispielsweise als Elektromotor, der über ein Spindelgetriebe eine Schubstange antreibt, die die Verstellbewegung auf die Kopfstütze überträgt. Dies hat den Nachteil, dass bei der Herstellung kein separat vormontiertes Kopfstützenmodul eingesetzt werden kann, das lediglich durch einige Befestigungsschrauben oder Ähnliches mit der Behandlungsliege verbunden werden muss. Ferner kann man mit der erfindungsgemäßen Lösung auch bei der Wartung oder Nachrüstung einer Behandlungsliege Vorteile erzielen, indem sich die Kopfstütze als komplette Funktionseinheit abnehmen lässt und wegen Reparaturbedürftigkeit oder Aktualisierungs- oder Umbauwunsch gegen eine andere Kopfstütze austauschen lässt.The prior art has instead installed the drive in the treatment couch, for example, as an electric motor which drives a push rod via a spindle gear, which transmits the adjustment movement to the headrest. This has the disadvantage that in the production no separately pre-assembled headrest module can be used, which only needs to be connected by some mounting screws or the like with the treatment table. Furthermore, one can achieve advantages with the solution according to the invention in the maintenance or retrofitting of a treatment table by the headrest can be removed as a complete functional unit and can exchange for another need for repair or updating or modification request against another headrest.
Vorzugsweise ist die vertikale Z-Verstellbarkeit der Kopfstütze durch eine Schwenkbewegung realisiert, zu der nur ein einziger Antrieb erforderlich ist. Insb. kann dabei die im Wesentlichen senkrecht zu der vertikalen Z-Richtung und ferner im Wesentlichen senkrecht zu der Längserstreckung der Behandlungsliege verlaufende Schwenkachse auf der der Behandlungsliege zugewandten Seite oder in Gelenkpunkten an der Behandlungsliege vorgesehen sein.Preferably, the vertical Z-adjustability of the headrest is realized by a pivoting movement, to which only a single drive is required. Esp. may be substantially perpendicular to the vertical Z-direction and further substantially perpendicular to the longitudinal extent of the treatment couch extending pivot axis may be provided on the side facing the treatment couch or in articulation points on the treatment couch.
Bevorzugt ist ferner ein Zahnstangenantrieb, und zwar insb. in Verbindung mit der geschilderten Schwenkbewegung. Zur Illustration wird auf das Ausführungsbeispiel verwiesen. Ein Zahnstangenantrieb ist i. d. R. einfacher und unproblematischer als beispielsweise ein angetriebenes Spindelgetriebe oder ein Linearmotor. Vorzugsweise verfügt der Zahnstangenantrieb über eine Führung für die Zahnstange selbst, die ihrerseits drehbar ist, um die Verkippung der Zahnstange während der Schwenkbewegung der Kopfstütze auszugleichen. Die Zahnstange ist ferner vorzugsweise hohl und kann dann dazu dienen, in geschützter Weise Leitungen zwischen der Kopfstütze und der Behandlungsliege zu führen.Also preferred is a rack and pinion drive, in particular in conjunction with the described pivoting movement. For the sake of illustration, reference is made to the exemplary embodiment. 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, which in turn is rotatable to compensate for the tilt of the rack during the pivotal movement of the headrest. The rack is also preferably hollow and may then serve to guide conduits between the headrest and the treatment couch in a protected manner.
Grundsätzlich sind bei dieser Erfindung motorische Antriebe der Z-Verstellung der Kopfstütze bevorzugt. Dies gilt insb. für elektromotorische Antriebe. Bei einer weiteren bevorzugten Ausgestaltung werden diese in einer auf Verstellbewegungen der Behandlungsliege abgestimmten Weise angesteuert, so dass insb. ein automatischer Neigungsausgleich der Kopfstütze erfolgen kann, wenn die Behandlungsliege bzw. deren Liegeplatte gekippt wird. Diese Kippbewegung der Liegeplatte kann u. a. dadurch auftreten, dass eine vertikale Z-Verstellung der Liegeplatte durch eine Schwenkbewegung derselben erfolgt und die zugehörige Schwenkachse von der Kopfstütze entfernt liegt. Der automatische Neigungsausgleich ermöglicht dann eine Konstanthaltung der Winkelorientierung der Kopfstütze, d.h. beispielsweise eine durchweg waagrechte Lage der Kopfstütze. Von besonderem Vorteil ist dies bei Behandlungen des Kopfes des Patienten.Basically, motor drives of the Z-adjustment of the headrest are preferred in this invention. This applies esp. For electric motor drives. In a further preferred embodiment, these are controlled in a manner adapted to adjusting movements of the treatment couch, so that esp. An automatic tilt compensation of the headrest can be done when the treatment table or its deck plate is tilted. This tilting movement of the deck plate can u. a. occur because a vertical Z-adjustment of the deck plate by a pivoting movement thereof takes place and the associated pivot axis is remote from the headrest. The automatic tilt compensation then makes it possible to keep constant the angular orientation of the headrest, i. for example, a consistently horizontal position of the headrest. This is particularly advantageous in treatments of the patient's head.
Bei einer weiteren bevorzugten Ausführungsform verfügt die Kopfstütze ferner über eine X-Verstellung gegenüber der Liegeplatte, und zwar vorzugsweise ebenfalls durch eine Schwenkbewegung um eine nun parallel zu der Z-Richtung liegende Drehachse. Auch diese Verstellung erfolgt vorzugsweise motorisch. Auch hier ist es bevorzugt, dass die X-Verstellung in einer (mechanisch oder motorisch) auf eine X-Verstellung der Liegeplatte angepassten Weise erfolgen kann, um bei Schwenk-X-Verstellungen der Liegeplatte einen entsprechenden Winkelausgleich in der Kopfstütze zu erhalten. Dann kann nämlich der Patientenkopf in X-Richtung verschoben werden, ohne dass dabei im Bereich des auf der Kopfstütze liegenden Patientenkopfes ein Winkelfehler auftritt. Allerdings sind die auftretenden Winkelfehler, wenn auf diese Option verzichtet wird, auch nicht so groß, dass dies bei allen Anwendungsfällen zu einem Problem führen müsste.In a further preferred embodiment, the headrest further comprises an X-adjustment relative to the deck plate, and preferably also by a pivoting movement about a now lying parallel to the Z-direction of rotation axis. This adjustment is preferably motorized. Again, it is preferred that the X-adjustment can be done in a (mechanically or motorized) adapted to an X-adjustment of the deck plate manner, in order to pivot-X adjustments of the deck plate a corresponding angle compensation in the headrest to obtain. Then namely the patient's head can be moved in the X direction, without causing an angle error occurs in the region of lying on the headrest patient head. However, if this option is omitted, the angle errors that occur are not so great that this would lead to a problem in all applications.
Für die technische Ausführung der X-Verstellung der Kopfstütze durch eine Schwenkbewegung gelten sinngemäß die Ausführungen zu der Z-Verstellung.For the technical implementation of the X-adjustment of the headrest by a pivoting motion apply mutatis mutandis to the versions of the Z-adjustment.
Wenn eine erfindungsgemäß modulartig an der Behandlungsliege montierte Kopfstütze verstellt wird, kann es zu einer Klemmgefahr kommen. Dies gilt insb. für ein Hochschwenken des distalen Endes der Kopfstütze relativ zur Behandlungsliege, wobei die obere Liegefläche der Kopfstütze auf die Behandlungsliege zu bewegt wird. Die Erfindung sieht hierbei vor, ausreichende Abstände zu belassen, so dass insb. das Behandlungspersonal keiner Klemmgefahr unterliegt. Da andererseits für den Patienten eine zumindest im Wesentlichen durchgehende Liegefläche geschaffen werden soll, ist es bevorzugt, ein ohnehin günstiges Polster auf der Kopfstütze über deren feste Teile hinaus zu verlängern, so dass solche Sicherheitszwischenräume abgedeckt werden. Als zusätzliche Maßnahme kann vorgesehen sein, das Polster auf der Kopfstütze lediglich über einen Klettverschluss und möglicherweise weitere durch direktes Abziehen lösbare Befestigungsmittel, etwa Zentrierstifte o. Ä, zu halten. Sollte von dem Polster eine Klemmwirkung ausgehen, so kann sich dieses leicht von dem Klettverschluss und den möglichen anderen Befestigungsmitteln lösen, womit größere Klemmkräfte vermieden werden können.If a headrest according to the invention mounted in a modular manner on the treatment couch is adjusted, a risk of jamming can occur. This applies esp. For a pivoting of the distal end of the headrest relative to the treatment table, wherein the upper bed surface of the headrest is moved to the treatment couch. The invention provides in this case to leave sufficient distances, so that esp. The treatment personnel is not subject to any risk of jamming. On the other hand, since an at least substantially continuous lying surface is to be created for the patient, it is preferable to extend an already favorable cushion on the headrest beyond its fixed parts, so that such safety gaps are covered. As an additional measure can be provided to hold the pad on the headrest only via a hook and loop fastener and possibly further detachable by direct removal fasteners, such as centering pins o. Ä. Should a cushioning effect from the pad, this can easily be released from the hook and loop fastener and the possible other fastening means, whereby greater clamping forces can be avoided.
Es wurde bereits ausgeführt, dass bei der Erfindung vorzugsweise die Z-Verstellung und die X-Verstellung über die geschilderten Schwenkbewegungen erfolgen. Andererseits ist es erfindungsgemäß bevorzugt, die Y-Verstellung, also die Verstellung in der Längsrichtung, weiterhin in an sich bekannter Weise über eine Linearführung vorzunehmen. Da die Y-Verstellung nicht gravitationsparallel erfolgt, kann es hier ausreichen, einen einzigen Lineartrieb, etwa einen Spindeltrieb, zu verwenden, und die Liegeplatte im Übrigen in Y-Richtung verschieblich zu lagern. Bei der Erfindung ist im Übrigen bevorzugt, dass die Y-Verstellbewegung gegenüber der ortsfesten Basis erfolgt und weiterhin bevorzugt, dass die X-Verstellung den Z-Verstellungsmechanismus "mitnimmt", also gewissermaßen zwischen die Y-Verstellung und die Z-Verstellung zwischengeschaltet ist. Dadurch kann auch die X-Verstellung von Gravitationseinflüssen frei bleiben und kann sich die Z-Verstellung auf die Bewegung vergleichsweise kleinerer Bestandteile der gesamten Behandlungsliege beschränken.It has already been stated that in the invention preferably the Z-adjustment and the X-adjustment take place via the described pivoting movements. On the other hand, it is preferred according to the invention, the Y-adjustment, so the adjustment in the longitudinal direction, continue to make in a conventional manner via a linear guide. Since the Y-adjustment is not carried out gravitationally parallel, it may be sufficient here to use a single linear drive, such as a spindle drive, and to store the deck plate, moreover, displaceably in the Y direction. Incidentally, in the invention, it is preferable that the Y-displacement move from the fixed base, and further that the X-displacement be the Z-displacement mechanism "entrains", so to speak, between the Y-adjustment and the Z-adjustment is interposed. As a result, the X-adjustment of gravity influences remain free and can limit the Z-adjustment to the movement of relatively smaller components of the entire treatment couch.
Die Behandlungsliege kann einen Stützfuß aufweisen, der bei der X-Verstellung mitgenommen wird und an einem bzgl. der X-Verstellung drehachsenfernen Teil der Behandlungsliege montiert ist, vorzugsweise in der Nähe des Schulter- oder Kopfbereichs des Patienten. Dadurch kann bei einem Ausfahren der X-Bewegung infolge des Stützfußes eine verbesserte Gesamtstabilität erreicht werden.The treatment couch may comprise a support leg, which is entrained in the X-adjustment and is mounted on a with respect to the X-adjustment rotary axis remote part of the treatment table, preferably in the vicinity of the shoulder or head region of the patient. As a result, an improved overall stability can be achieved when extending the X-movement as a result of the support foot.
Ein bevorzugter Anwendungsbereich für die erfindungsgemäße Behandlungsliege liegt in Bestandteilen medizinischer Geräte zur Behandlung des Kopfes und insbesondere des Auges. Ferner bezieht sich die Erfindung vorzugsweise auf Geräte zur Behandlung des menschlichen Körpers, kann jedoch auch bei Behandlungsliegen für Tiere eingesetzt werden. Ein besonders bevorzugter Bereich ist die Laserchirurgie am menschlichen Auge, bei der durch die erfindungsgemäße Behandlungsliege das behandelte Auge in die richtige Position für den laserchirurgischen Eingriff gebracht werden kann.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 the treatment of the human body, but can also be used in treatment beds for animals. A particularly preferred area is the laser surgery on the human eye, in which the treated eye can be brought into the correct position for the laser surgery by the treatment couch according to the invention.
Schließlich bezieht sich die Erfindung auch auf ein Verfahren zur Lagerung eines Patienten unter Verwendung der beschriebenen Behandlungsliege. Die vorstehende und die nachfolgende Beschreibung der Behandlungsliege in ihren vorrichtungsmäßigen Einzelheiten sind gleichzeitig als Offenbarung des genannten Verfahrens zu verstehen.Finally, the invention also relates to a method for storing a patient using the described treatment couch. The foregoing and following description of the treatment couch in its device details is to be understood as a disclosure of said method.

Die Befestigungsschrauben greifen in eine Metallplatte 30 mit entsprechenden Gewinden, um die im Übrigen aus Kunststoff gefertigte Halteplatte 28 zu entlasten. Sie halten ferner in der Halteplatte 28 einen Gelenkkasten 31, in dem die bereits anhand der
Wie die folgenden Figuren noch näher darstellen, ist an der Halteplatte 28 über zwei über bzw. unter der Zeichenebene liegende Gelenkkästen mit entsprechenden Kipphebeln die eigentliche Kopfschale 32 der Kopfstütze 3 angelenkt. Diese Kopfschale 32 besteht aus einem anatomisch geformten oberen Teil 33 und einem darunter angesetzten Gehäuseteil 34, in den die bereits erwähnte Zahnstange 26 hineinragt. In dem Gehäuseteil 34 ist ein unter der Zeichenebene angeordneter Elektromotor 27, der schon in
Die Kopfauflage 33 besteht im Wesentlichen aus einem weichen Schaumstoffpolster 36, das über einen Klettverschluss 37 an einer oberen Platte des Gehäuseteils 34 angebracht ist.

Die dargestellte Behandlungsliege ist integraler Bestandteil eines nicht in weiteren Einzelheiten dargestellten und an sich bekannten Laserchirurgiegeräts zur Behandlung von Fehlsichtigkeit im menschlichen Auge. Über der Kopfstütze 3 ist der Kopf dieses Geräts angebracht und lenkt einen in Z-Richtung verlaufenden Laserstrahl in das Auge, das dazu mit der Behandlungsliege in die geeignete Position gebracht werden muss. Durch X-Verstellung kann zwischen den beiden Augen des Patienten hin- und hergeschaltet werden. Die optischen Verstellmöglichkeiten des Lasergeräts selbst müssen damit lediglich die Feinbewegungen des Laserstrahls bei der eigentlichen Behandlung abdecken. Die Positionierung des Patienten erfolgt davon unabhängig über die Behandlungsliege.
