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.

  • 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 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 already mentioned holding plate 28 in this case via a motor-driven Rack 46 with motor 45 on one outer side (seen in the X direction) and mounted via a hinge 47 on the opposite outer side.
  • 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.
  • This support leg 48 is shown here only symbolically and can be driven in practice to stand out during adjustment movements from the ground and set up after adjustment for stabilization.
  • the lower end of the support leg 48 may also be provided with a roll rolling on the ground or a sliding surface.
  • the support leg 48 is attached to an end plate, which in turn is connected to the aforementioned intermediate plate 14, which in turn can be pivoted about the axis 13 relative to the base 4.
  • the illustrated treatment couch is an integral part of a laser surgical unit, not shown in further detail and known per se, for the treatment of ametropia in the human eye.
  • 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 optical adjustment options of the laser device itself must therefore cover only the fine movements of the laser beam in the actual treatment.
  • the positioning of the patient takes place independently of this via the treatment couch.
  • 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. You have to get the deck plate 1 off FIG. 13 and the following figures instead of the previously only schematically indicated deck plate 1 in the figures described so far.
  • the deck plate 1 carries a multipart mattress 2 with a shown in the right part and in relation to the deck plate 1 fixed mattress part and other shown in the left part of three mattress parts corresponding to the described in more detail below and summarily denoted by 51 knee brace.
  • the knee brace 51 has a thigh portion 52 and a lower leg portion 53.
  • the comparison of Figures 13 and 14 shows that the height of the knee brace 51 in the transition from the thigh portion 52 to the lower leg portion 53 is adjustable by an adjusting mechanism still described below.
  • FIGS. 15 and 16 correspond to the Figures 13 and 14 with the difference that there is the knee brace 51 in the direction to the right, ie in the longitudinal direction of the deck plate 1 to the headrest out, moved.
  • FIG. 17 shows one FIG. 14 corresponding view, wherein at the bottom of a side cover on the deck plate 1 is omitted, so that a front longitudinal rail 54 is visible.
  • the Figures 18 and 19 correspond to the Figures 13 and 14 However, show the deck plate without the stationary part of the mattress 2 and without the panel around the in FIG. 17 illustrated longitudinal rail 54 and a parallel thereto further longitudinal rail 55 in perspective.
  • FIG. 21 corresponds to FIG. 18 however, is a perspective bottom view
  • FIG. 20 FIG. 19 corresponds and not in perspective from the foot, but seen from the headboard.
  • FIG. 22 again shows the deck plate 1 in bottom view.
  • a lever 56 for the adjustment of the knee brace 51 by lifting the knee-side ends of the thigh portion 52 and the lower leg portion 53 is responsible.
  • the hip-side end of the thigh portion 52 is, in particular the Figures 18 . 19 and 20 show, hinged to a first bearing plate 57.
  • the lever 56 in turn is hinged at its lower end to a second bearing plate 58, in particular FIG. 19 shows.
  • FIG. 21 shows particularly clearly that the bearing plates 57 and 58 are mounted on the guide rails 54 and 55 via three guides 59-64.
  • the guides 61 and 62 each contain an internal thread, ie a nut, and are guided on a section of the respective guide rail 54 or 55 provided with an external thread.
  • the threaded portion on the guide rail 54 extends from the right end of the guide rail 54 on the guide 61 also left to the in the Figures 18-22 recognizable mark.
  • the threaded portion of the guide rail 55 in turn extends from the left end of the guide rail over the guide 62 out to the in the Figures 21 and 22 recognizable mark.
  • the guide rails 54 and 55 are smooth on the outside. They are driven by electromotive drives not shown in detail, cf. the reference numerals 65 and 66 in the Figures 21 and 22 ,
  • FIGS. 17 to 22 clarify how the in the FIGS. 13 to 16 let execute adjusting movements shown.
  • guide rail 55 When driving the integrated spindle bar for the nut-provided guide 62, guide rail 55 is driven, the second support plate 58 moves toward the headrest or in the opposite direction.
  • the guide 59 slides over the guide rail 54 and the first bearing plate 57 remains unmoved. This results in an adjustment of FIG. 13 to FIG.
  • a substantially cylindrical slider 68 is mounted, with which the lower leg portion 53 slides during the adjustment movements on the underlying horizontal bearing plate 58.
  • the foot-side end of the lower leg portion 53 remains substantially at the same height as the upper body portion 67 and thus in its flight.
