    DESCRIPTION OF EMBODIMENTS OF THE INVENTION
    Figures 1-4 show in different directions an operating table 10 according to an embodiment of the invention. The operating table 10 is adapted to support a patient during various surgical procedures. The operating table 10 comprises 5 frames (not shown in Figures 1-4) and a table top 11 supported by the frame, on which the patient is on during the procedure. In the embodiment of the figures, the table top 11 comprises a first part 11a and a second part 11b. In Figures 1-4, both parts 11a, 11b of the table top 11 are in a horizontal position. However, the first part 11a and the second part 11b can be turned at different angles to each other and to the floor. The table top 11 could also be one-piece or multi-piece. In the case of a multi-part table top, two or more parts could be movable and / or pivotable relative to each other. The table top 11 can be provided with various accessories, for example to keep the patient in a certain position or to support the patient's limbs.
    The operating table 10 is provided with a height adjustment arrangement. To protect the height adjustment arrangement and to facilitate the cleaning of the operating table, the height adjustment arrangement is arranged inside the housing 12. The housing 12 comprises a fixed part 12a and an adjustable part 12b. The adjustable portion 12b allows the height of the cutting table 10 to be adjusted so that the height adjustment arrangement 20 remains protected. In the embodiment of the figures, the adjustable part 12b is an accordion or bellows structure. The adjustable part 12b is made of a flexible and corrugated material. The lower edge of the adjustable portion 12b is attached to the fixed portion 12a and the upper edge is attached to the support structures of the table top 11. Instead of a bellows structure, another type of adjustable part, such as a telescopic structure, could also be used. For example, the assembly 12 may be made of one or more suitable plastic materials.
    The operating table 10 also comprises a frame housing 13 which protects the frame of the operating table 10 and facilitates its cleaning. The operating table body 8 can be seen in Figures 5-8. The term “frame” as used herein refers to the lower portion of the structure of the operating table 10, i.e., the lower frame that supports the operating table 10 against the floor.
    A height adjustment arrangement is arranged between the frame 8 and the table top 11, by means of which the height position of the table top 11 with respect to the floor-supported frame 8 can be adjusted. By means of the height adjustment arrangement, the table top 11 can thus be moved vertically. In the embodiment of the figures, the frame 8 comprises a run beam 14. The frame beam 14 is parallel to the longitudinal axis 6 of the table plane.
    20175823 prh 18 -09- 2017 with the direction. A transverse support 15a, 15b is arranged at each end of the frame beam 14. Two wheels are attached to each of the transverse supports 15a, 15b
    16. The frame 8 is provided with a lifting mechanism by means of which the position of the wheels 16 can be changed between the upper position and the lower position. In the lower position of the wheels 16, the cutting table 10 rests on the wheels 16 and is thus easily movable. In the upper position of the wheels, the cutting table 10 in turn descends on the support legs 17 fixed to the frame 8 and thus remains firmly in place. The lifting mechanism of the wheels 16 is not described in more detail here. The above is just one example of a possible frame structure for the operating table 10. The height adjustment arrangement according to the invention could also be used in connection with many other types of frame construction. Thus, for example, the cutting table 10 does not have to be provided with wheels 16. The frame 8 could be implemented with different beam structures or, for example, with a plate structure.
    The height adjustment arrangement according to an embodiment of the invention is par15 least seen in Figures 7-11. Figures 7 and 8 show the height adjustment arrangement attached to the frame 8 of the cutting table 10 and in its upper position. Figure 9 shows the height adjustment arrangement detached from the body 8 in its lower position. Fig. 10 shows the height adjustment arrangement in its upper position and Fig. 11 a sectional view of Fig. 10.
    The height adjustment arrangement according to the invention comprises a first rack 1, a second rack 2, a lifting element 3, at least one gear 4a, 4b, 4c and an actuator 7. The first rack 1 is adapted to be fixedly attached to the body 8 of the cutting table 10. The lifting element 3 is adapted to be linear regarding. The second rack 2 is adapted to be linearly movable relative to the lifting element 3. The lifting element 3 is further adapted to be fixed to the table level 11 of the cutting table 10. The gear 4a, 4b, 4c is rotatably connected to the lifting element 3. The gear 4a, 4b, 4c is further connected to operate with the teeth of the first rack 1 and the second tooth30. with respect to the first rack 1 moves the second rack 2 linearly with respect to the lifting element 3. The actuator 7 is arranged to move the lifting element 3 linearly with respect to the first rack 1.
    With the height adjustment arrangement according to the invention, the second rack 2 and the table top 11 of the si35 are made to move at a higher speed than the lifting element.
    20175823 prh 18 -09- 2017 ment 3. The travel of the second rack 2 is also greater than the travel of the lifting element 3. Thus, a small travel of the actuator 7 results in a larger travel of the table level 11. This results in a low height adjustment arrangement. The structure is also simple.
    In the embodiment of the figures, the height adjustment arrangement comprises three gears 4a, 4b, 4c. All the gears 4a, 4b, 4c are rotatably attached to the lifting element 3. The first gear 4a is connected directly to the toothing of the first rack 1. The linear movement of the lifting element 3 with respect to the first rack 1 thus rotates the first gear 4a. The second gear 4b is connected directly to the toothing of the second rack 2. The rotational movement of the second gear 4b thus moves the second rack 2 linearly with respect to the lifting element 3. A third gear 4c is arranged between the first gear 4a and the second gear 4b and connected directly to the teeth of both gears 4a, 4b. The rotational movement of the first gear 4a thus rotates the third gear 4c, which transmits the rotational movement to the second gear 4b. In the embodiment of the figures, all gears 4a, 4b, 4c have the same number of teeth. All gears 4a, 4b, 4c thus rotate at the same speed. The direction of rotation of the third gear 4c is opposite to the direction of rotation of the first and second gears 4a, 4b.
    The first rack 1 and the second rack 2 are arranged parallel to each other. The longitudinal axes of the racks 1, 2 are thus parallel. In the operating position of the height adjustment arrangement, the racks 1, 2 are arranged vertically. In the embodiment of the figures, the racks 1,2 are arranged so that their teeth point towards each other. However, the racks 1, 2 could alternatively be arranged so that their teeth point in the same direction.
    The axes of rotation of the gears 4a, 4b, 4c are parallel to each other. The axis of rotation of each gear 4a, 4b, 4c is located in a plane perpendicular to the longitudinal directions of the racks 1, 2. The axes of rotation are thus located in horizontal planes. In the operating position of the height adjustment arrangement, the first gear 4a is located at the lowest, the third gear 4c is located above the first gear 4a, and the second gear 4b is located above the third gear 4c.
    20175823 prh 18 -09- 2017
    The height adjustment arrangement could also be implemented with a number of gears other than three gears 4a, 4b, 4c. When the racks 1, 2 are arranged according to the figures so that their teeth are facing each other, there are preferably an odd number of gears. Then, the gears 4a, 4b directly connected to the first rack 1 and the second rack 2 have the same direction of rotation. As a result, the direction of movement of the lifting element 3 and the second rack 2 is always the same.
    If the racks 1, 2 had been arranged so that their teeth point in the same direction, there would preferably be an even number of gears. With the teeth of the tooth bars 1, 2 pointing in the same direction, at least one gear should be axially wider than at least one of the racks 1, 2 or alternatively two gears should be attached to the same shaft so that the first and second racks 1, 2 can be placed side by side so that the lifting element 3 can be transmitted by tooth15 via wheels to another rack 2.
    The arrangement could also be implemented with a single gear, in which case the gear would be connected directly to the teeth of both the first rack 1 and the second rack 2. However, in the lower position of the arrangement, the second rack 2 should extend vertically below the first rack 20, which would increase the height of the height adjustment arrangement. Therefore, there are preferably more than one gear. There could also be five gears, for example. In this case, the rotational movement of the first gear 4a would be transmitted to the second gear 4b via more than one gear 4c.
    The height adjustment arrangement comprises a fixed lifting beam 5. The fixed lifting beam 5 is fixed to the frame 8 of the cutting table 10. In the embodiment of the figures, the fixed lifting beam 5 is fixed to the frame beam 14. The first rack 1 is fixed to the fixed lifting beam 5 by means of screws 17. The cross-sectional profile of the fixed lifting beam 5, viewed from the end of the first rack 1, i.e. 30 in the horizontal plane, is C-shaped. The fixed lifting beam 5 thus forms guide surfaces 5a, 5b for the lifting element 3.
    The lifting element 3 is an elongate body whose longitudinal axis is parallel to the first rack 1. Guide surfaces 3a, 3b are formed on the lifting element 3, which rest on the guide surfaces 9 of the lifting beam 5.
    20175823 prh 18 -09- 2017 hin 5a, 5b. By means of the fixed lifting beam 5 and the guide surfaces 5a, 5b, 3a, 3b of the lifting element 3, the movement of the lifting element 3 is prevented in a plane perpendicular to its desired direction of movement. The guide surfaces 3a, 3b, 5a, 5b thus leave one degree of freedom for the lifting element 3, which allows it to move vertically. The Nos5 support element 3 could also be supported in some other way. The height adjustment arrangement could thus comprise other types of control means for controlling the linear movement of the lifting element 3. Thus, the height adjustment arrangement could comprise, for example, one or more linear guides separate from the fixed lifting beam 5, which can be attached to the frame 8 of the cutting table 10, and the lifting element 3 one or more guide surfaces resting on the linear guide. Alternatively, the linear guide could be attached to the lifting element 3 and the guide surface arranges the cutting table 10 immobile relative to the body 8.
    The second rack 2 is attached to the movable lifting beam 6. The movable lifting beam 6 also has a C-profile which forms the guide surfaces 6a, 6b. The guide surfaces 6a, 6b of the movable lifting beam 6 rest on the second guide surfaces 3c, 3d of the lifting element 3. The guide surfaces 3c, 3d, 6a, 6b of the lifting element 3 and the movable lifting beam 6 prevent the movement of the movable guide beam 6 in a plane perpendicular to its desired direction of movement. The guide surfaces 3c, 3d, 6a, 6b thus leave one degree of freedom on the movable lifting beam 6, which allows it to move vertically. The mobile lifting beam 6 could also be supported in alternative ways. Thus, the height adjustment arrangement could be provided with other types of control means for controlling the linear movement of the movable lifting beam 6. The movable lifting beam 6 could be guided, for example, directly by one or more linear guides attached to the frame 8 of the cutting table 10.
    By means of the movable lifting beam 6, the second rack 2 is fixedly fixed to the table top 11. In the embodiment of the figures, the movable lifting beam is fixed to the frame structure 19 of the table top 11. The first part 11a and the second part 11b of the table top 11 can be arranged to rotate and / or move A fastening element 18 is arranged at the upper end of the movable lifting beam 6, by means of which the frame structure 19 of the table top 11 can be fastened to the movable lifting beam 6.
    In the embodiment of the figures, the axes of rotation of the gears 4a, 4b, 4c are not arranged in the same vertical plane. The gears 4a, 4b, 4c are arranged so that the vertical plane in which the axis of rotation of the third gear 35 4c is located is further from the first rack 1.
    20175823 prh 18 -09- 2017 than the vertical plane on which the axis of rotation of the first gear 4a is located. Correspondingly, the vertical plane in which the axis of rotation of the second gear 4b is located is farther from the first rack 1 than the plane of the axis of rotation of the third gear 4c. As a result, the second gear 4b is further away from the first rack 1 than the first and third gears 4a, 4c, so that the second rack 2 is also directly connected to the second gear 4b in its lower position. Correspondingly, the first rack 1 is directly connected only to the first gear 4a. The axis of rotation of the third gear 4c 10 could also be in the same plane as the first gear
    4a or with the shaft of the second gear 4b if the diameter of the third gear 4c is smaller than the diameter of the first and / or second gear 4a, 4b. Also, the axes of rotation of the first gear 4a and the second gear 4b could be in the same plane with each other, but in some cases it could limit the travel of the lifting element 3 and the movable lifting beam 6.
    In the embodiment of the figures, the gear numbers of the gears 4a, 4b, 4c are equal. Likewise, the diameters of the gears 4a, 4b, 4c are equal. The tooth spacing of the gears 4a, 4b, 4c and the racks 1, 2 is also 20 equal. With such an arrangement, the movement speed of the movable lifting beam 6 is twice the movement speed of the lifting element 3 and the movement distance of the moving lifting beam 6 is twice the movement distance of the lifting element 3. It would also be possible to implement the height adjustment arrangement in such a way that the teeth of the first and second racks 1, 2 would be different. This could be achieved, for example, by arranging two gears on the same shaft, one connected to the first rack 1 and the other to the second rack 2. Such an arrangement could provide various ratios of the travel of the movable lifting beam 6 and the lifting element 3.
    The actuator 7 may be an electric motor, such as a linear spindle motor or another linear motor, the motor being arranged to produce linear motion. A motor producing linear motion can be arranged to directly move the lifting element 3. Other types of electric motor, such as a stepper motor or a servomotor, could also be used. In that case, the motor can be connected directly or via a gear, such as a bevel gear, to a linear guide arranged to move the lifting element 3. For example, the motor can be arranged to rotate the screw of the linear guide. Instead of an electric motor, a hydraulic cylinder or a pneumatic cylinder, for example, could also be used as the actuator 11. The height adjustment arrangement comprises a control unit which controls the operation of the actuator 7.
    In the embodiment of the figures, the actuator is a spindle motor 7. The spindle motor 7 is fixed to the frame structure 8 of the cutting table so that its axis of rotation is horizontal, i.e. perpendicular to the direction of movement of the lifting element 3. By means of the bevel gear, the rotational movement of the spindle motor 7 is converted into a vertical movement of the lifting rod 20. The lifting rod 20 is attached at its upper end to the lifting element 3. By controlling the spindle motor 7, the lifting rod 20 can be moved 10 between the lower position shown in Fig. 9 and the upper position shown in Figs. 7, 8, 10 and 11. The control of the spindle motor 7 is preferably implemented in such a way that the lifting rod 20 can also be moved to the desired positions between the lower position and the upper position.
    In the embodiment of the figures, the operating table 10 is provided with a wireless remote control 21 by means of which the height adjustment arrangement can be controlled. Other functions of the cutting table 10 can also be used with the remote control, such as adjusting the inclination of the parts 11a, 11b of the table top 11. The operating table 10 further comprises a control panel 22 through which the height adjustment arrangement and other functions can be controlled. In the embodiment of the figures, the control panel 22 is arranged in the housing 12 of the cutting table 10.
    It will be apparent to those skilled in the art that the invention is not limited to the embodiments described above, but may vary within the scope of the appended independent claims.
