Description

[0001] Operating table with a device for adjusting the position of a movable operating table section

[0002] Technical area

[0003] The present disclosure relates to operating tables that have the ability to move a movable part of the operating table relative to a fixed part and to adjust a position of the movable part relative to the fixed part. Furthermore, the disclosure relates to a method for operating such an operating table.

[0004] Background of the Revelation

[0005] During medical examinations or surgical procedures, patients can be positioned on operating tables. A movable part of the operating table can be manually moved by a user relative to the fixed part and placed in a desired position. This allows the operating table to be adjusted as required for the planned procedure or examination.

[0006] Several specific positions can be predefined that the movable part can assume relative to the fixed part. The user can select one of these positions. It would be desirable to make the adjustment options flexible, so that the adjustment positions are not fixed but can be adjusted. This would allow the operating table to be adapted to new or changing requirements while still meeting the user's individual positioning preferences.

[0007] Summary of Revelation

[0008] It is an object of the present disclosure to provide an operating table with a movable part, wherein the positions that the movable part can assume relative to the fixed part can be changed. An operating table according to a first aspect of the present disclosure can have a fixed part that is designed to stand on a floor or surface, and a movable part that is mounted in particular on or in the fixed part and can be moved relative to the fixed part. Alternatively, the fixed part may not be in direct contact with the floor, but may be attached to another part of the operating table. One of the two parts, i.e. either the fixed part or the movable part, can have a holding element or locking element, which can in particular be a lever.The other of the two parts can have one or more fixing elements, such as locking elements or stop elements. In particular, it can be provided that the other part has two or more fixing elements, in particular locking elements or stop elements. When the holding element is fixed to the fixing element, for example, engages one of the locking elements, the movable part can assume a predetermined position relative to the fixed part. The position of at least one of the fixing elements, in particular locking elements or stop elements, can be adjustable. The positions of several or all of the fixing elements, in particular locking elements or stop elements, can also be adjustable. The position(s) of the fixing element(s), in particular locking elements or stop elements, can in particular be adjustable in order to be able to set one or more predetermined positions of the movable part relative to the fixed part.

[0009] The following description refers to locking elements. More generally, these can be fixing elements. A fixing element can fix the holding element in a specific position. The mobility of the holding element in at least one direction can thus be blocked by means of the fixing element. As an alternative to a locking element, a stop element can be provided. Although the following text refers to locking elements, these can generally be fixing elements and, as an alternative, in particular also stop elements. In some embodiments, for example, the column with the holding element could be moved against a stop element and, if necessary, the holding element can be moved inwards to enable rotation beyond the stop element. The movable part can be mounted on or in the stationary part.It may also not be stored in or on the other part, but can be stored independently.

[0010] The position of the locking elements can be selected so that defined positions of the movable part can be repeatedly and accurately reached. During manual adjustment of the movable part, the user receives haptic feedback when the retaining element engages with one of the locking elements, indicating that a specific position has been reached. The haptic feedback provided by the retaining element engaging with one of the locking elements helps the user target specific positions when adjusting the movable part.

[0011] When the position of at least one of the locking elements is adjusted, the position assumed by the movable part relative to the stationary part is simultaneously changed when the retaining element engages the locking element. Adjusting the position of at least one locking element therefore allows the operating table to be adapted to new or changing requirements. Furthermore, the adjustable locking element(s) can be repositioned to suit the user's individual positioning requirements.

[0012] A further increase in user-friendliness is achieved in some embodiments in that the adjustable locking element(s) can be removed from the operating table and / or added to the operating table.

[0013] The operating table may comprise a base for placing the operating table on the floor, a vertically arranged operating table column, and a patient positioning system attached to an upper end of the operating table column. The base may also be referred to as the base of the operating table. The patient positioning system serves to support and position the patient and may be permanently connected to the operating table column or, alternatively, detachably attached to the operating table column. The patient positioning system may, for example, comprise a patient support device. Furthermore, the patient positioning system may comprise a support device attached to the upper end of the operating table column and a patient support device resting on the support device.

[0014] In some embodiments, the fixed part of the operating table can comprise at least part of the base, and the movable part can comprise the operating table column and the patient positioning system. For example, the interface between the fixed part and the movable part can be integrated into the base, such that the fixed part is a lower part of the base that stands on the floor, and an upper part of the base, together with the operating table column and the patient positioning system, is part of the movable part of the operating table. The upper part of the base, together with the operating table column and the patient positioning system, is movable relative to the lower part of the base. Furthermore, the interface between the fixed part and the movable part can be arranged between the base and the operating table column.

[0015] Alternatively, the fixed part may comprise the base, in particular the complete base, and at least part of the operating table column, and the movable part may comprise the patient positioning system. In this case, the interface between the fixed part and the movable part may, for example, be integrated into the operating table column or located between the operating table column and the patient positioning system.

[0016] In some embodiments, the movable part can be rotatable or pivotable relative to the fixed part. The movable part can be adjusted by a manual rotational movement, and the positions defined by the locking elements can be repeatedly approached. The adjustability of at least one of the locking elements enables flexible positioning. The rotational movement can extend over an angular range of up to 360°. Alternatively, in some embodiments, the movable part can be displaceable relative to the fixed part, in particular in a linear direction. The locking elements can be positioned at least partially flexibly over a desired length, so that the user can repeatedly approach the various positions by means of a manual linear movement.

[0017] In some designs, the operating table can be movable on the floor. The base of the operating table can have wheels or casters that allow the operating table to be moved on the floor.

[0018] Alternatively, in some designs the base can be firmly anchored to the floor.

[0019] As a further alternative, in some designs the base can stand freely on the floor and can be moved with the help of a transporter.

[0020] In some embodiments, the patient positioning system or patient support device can be configured such that the patient support device can be detachably connected to a movable surgical patient transporter and the column of the operating table. Before a surgical procedure, the patient support device can be mounted on the patient transporter. The patient can be transported to the operating table using the patient transporter. There, the patient support device can be attached to the operating table column and decoupled from the patient transporter. Much of the preparation for the surgical procedure can be performed while the patient support device is mounted on the patient transporter. For example, the patient support device can be assembled from individual segments and accessories, and the patient can be prepared for the surgical procedure.Only once the preparations are complete can the patient support device be attached to the operating table column. In some embodiments, the at least one adjustable locking element can be positioned at various locations along a predetermined path. The at least one adjustable locking element can be flexibly and removably attached along the predetermined path according to the respective requirements or the wishes of the operator.

[0021] The predetermined path can take various forms. In some embodiments, the predetermined path can be straight, circular, or arcuate.

[0022] In some embodiments, the predetermined path can be designed as a rail to which the at least one locking element can be releasably attached. Any number of locking elements can be attached to the rail in any desired position.

[0023] In some embodiments, the at least one adjustable locking element can be releasably attached to the rail using fastening means. The fastening means can, for example, be designed such that the at least one adjustable locking element is clamped to the rail. The at least one adjustable locking element can be attached to any desired location on the rail. The fastening means can be screws, for example grub screws. The fastening means can also be a clamping structure or a snap-in structure, for example. It can be provided that the locations at which the at least one adjustable locking element can be positioned are not determined by a grid along the rail or other specifications.

[0024] In some embodiments, the predetermined path can be circular or circularly arcuate. Furthermore, the at least one adjustable locking element can be attached along an inner surface of the predetermined path, and the retaining element can be arranged radially within the predetermined path. In particular, the retaining element can be biased radially outward in the direction of the predetermined path. In some embodiments, the retaining element can be reversibly movable between a locked position, in which the movable part assumes a predetermined position relative to the fixed part, and a release position, in which movement of the movable part relative to the fixed part is enabled.

[0025] In some embodiments, the retaining element may have a latching end for cooperating with the latching elements.

[0026] In some embodiments, the holding element can have a rotatably mounted roller at the locking end, which engages in one of the locking elements in the locked position. In particular, the rotatably mounted roller can roll over the locking element during movement of the movable part relative to the stationary part. The roller causes the holding element to move over the locking elements with little friction and little wear. The roller can be spaced from the rail to which the locking elements are attached such that the roller does not touch the rail. The roller can be attached such that the roller can only come into contact with the locking elements. The roller can automatically lock into the desired position as soon as the roller rolls over one of the locking elements.

[0027] In some embodiments, the retaining element can be rotatably or pivotably mounted at an end facing away from the locking end. Such a mounting allows the retaining element to engage with one of the locking elements. However, the retaining element can be mounted in a different manner.

[0028] In some embodiments, the holding element and the at least one adjustable locking element are designed such that, when the movable part moves relative to the stationary part, the holding element can move over the at least one adjustable locking element without stopping at the locking element. Although the movement of the movable part is not stopped when the holding element rolls over the at least one adjustable locking element, the holding element can, however, briefly lock into the locking element. The user perceives this haptically, so that they are informed of possible holding positions. In some embodiments, the locking elements can each have a recess for the positive and / or non-positive reception of at least one part of the holding element, in particular its locking end.If the locking end has a rotatably mounted roller, the recesses of the locking elements can be designed to receive at least part of the roller in a form-fitting and / or force-fitting manner.

[0029] If two or more locking positions are to be provided within a short distance of each other, the lateral extension of the locking elements can make this difficult or even impossible. In some embodiments, at least one of the locking elements can therefore have at least two recesses for the positive and / or non-positive reception of at least part of the retaining element or the locking end or the rotatably mounted roller. This enables multiple locking positions with a short distance between them.

[0030] In some embodiments, the locking elements can each have a ramp on at least one side of the recesses. Furthermore, a ramp can be provided on each of the two sides of the recesses. As soon as the retaining element encounters one of the locking elements during a movement of the movable part, it is pushed back by the respective ramp and subsequently engages in the recess of the locking element.

[0031] In some embodiments, the retaining element can be prestressed in a predetermined direction by a spring or prestressing element. In particular, the retaining element can be prestressed in the direction of the at least one locking element. In some embodiments, the retaining element can be prestressed radially outward, in particular in the direction of a curved or circular arrangement of locking elements. The prestressing of the retaining element causes the retaining element to lock into place as soon as the retaining element reaches the recess of a locking element.

[0032] In some embodiments, the operating table may have two or more locking elements whose positions along a common path can be adjusted independently of one another. The two or more locking elements may have the configurations described in the present application. In some embodiments, the operating table may have a releasable brake that the user can activate once the desired position of the movable part has been reached and the holding element has engaged the corresponding locking element. Once the brake has been activated, it prevents further adjustment of the movable part.

[0033] According to a second aspect of the present disclosure, a method for operating an operating table according to the first aspect is provided. The method comprises positioning the at least one adjustable locking element such that the movable part assumes a predetermined position relative to the fixed part when the holding element engages the at least one adjustable locking element.

[0034] The method according to the second aspect may have all configurations described in the present disclosure in connection with the operating table according to the first aspect.

[0035] In some embodiments, the movable part can be moved relative to the stationary part, and the movement can be stopped when the retaining element engages one of the locking elements. In some embodiments, a releasable brake can then be activated to prevent further movement or rotation.

[0036] In some embodiments, the position of the at least one adjustable locking element can be flexibly adjusted. In particular, the position of the at least one adjustable locking element can be adjusted between different locations along a track or rail.

[0037] The present disclosure also includes circuits and / or electronic instructions for controlling operating tables, as well as remote controls, displays, and user interfaces for use with operating tables.

[0048] Detailed character description

[0049] In the following description, exemplary embodiments of the present disclosure are described with reference to the drawings. The drawings are not necessarily to scale, but are intended merely to schematically illustrate the respective features.

[0050] It should be noted that the features and components described in this disclosure can be combined with each other, regardless of whether they have been described in connection with a single embodiment. The combination of features in the respective embodiments serves merely to illustrate the basic structure and operation of the claimed device.

[0051] In the figures, identical or similar elements are provided with identical reference numerals where appropriate.

[0052] Fig. 1 schematically shows an operating table 10 that can be used to support a patient 12 during a surgical procedure. The operating table 10 comprises, from bottom to top, a base 14 for placing the operating table 10 on a floor 16, an operating table column 18 connected to the base 14, a support device 20 attached to an upper end of the operating table column 18, and a patient support device 22 resting on the support device 20. The base 14 is firmly anchored to the floor. The support device 20 and the patient support device 22 together form a patient positioning system 24. The patient positioning system 24 can be firmly connected to the operating table column 18 or, alternatively, detachably attached to the operating table column 18.

[0053] The patient support device 22 can be modular and serves to support the patient 12. The patient support device 22 comprises a main support surface section 26, which can be expanded as required by coupling various secondary support surface sections. In Fig. 1, a head section 28 is coupled to the main support surface section 26 as a secondary support surface section. The patient support device 22 of the operating table 10 can be adjusted to a suitable height and can be tilted or angled depending on the type of surgical procedure to be performed. Furthermore, the patient support device 22 can be adjusted in the longitudinal direction.

[0054] The operating table column 18 can be height-adjustable and can have an internal mechanism for adjusting the height of the patient support device 22. The mechanism is arranged in a housing 30, which protects the components from contamination.

[0055] For better illustration, a Cartesian XYZ coordinate system is shown in Fig. 1. The X-axis and Y-axis are horizontal axes, and the Z-axis is a vertical axis. The X-axis indicates the longitudinal direction, and the Y-axis indicates the lateral direction of the patient support device 22.

[0056] As shown in Figs. 2 to 7, the operating table 10 has a fixed part 50 and a movable part 52. The fixed part 50 of the operating table 10 comprises a lower part of the base 14 and is fixedly attached to the floor 16. An upper part of the base 14 is movably mounted in the lower part and, together with the operating table column 18 and the patient positioning system 24, forms the movable part 52 of the operating table 10. The movable part 52 can be turned or rotated relative to the fixed part 50. Such movement can be achieved by a user manually moving the movable part 52.

[0057] At the interface between the fixed part 50 and the movable part 52, the fixed part 50 has a circular rail 54 to which locking elements 56, 58 are releasably attached. The rail 54 lies in a plane parallel to the plane defined by the X and Y axes.

[0058] The movable part 52 has a holding element 60 designed as a lever with a locking end 62, to which a rotatably mounted roller 64 is attached. Furthermore, the holding element 60 is biased toward the rail 54 by a spring 66. When the holding element 60 encounters one of the locking elements 56, 58 during rotation of the movable part 52 relative to the fixed part 50, the roller 64 of the holding element 60 engages in a recess 68 formed in the locking elements 56 and 58, respectively. The engagement of the holding element 60 causes a slight mechanical impulse, which the user perceives when adjusting the movable part 52.

[0059] The locking element 56 has exactly one recess 68, whereas the locking element 58 has two recesses 68. The recesses 68 have a cylindrical surface with a radius approximately equal to the radius of the cylindrical roller 64. The roller 64 can therefore engage positively in the recesses 68.

[0060] Fig. 2 and 5 show the roller 64 when it is engaged in the recess 68 of the locking element 56.

[0061] In Fig. 3 and 4, the roller 64 is not engaged in any of the locking elements 56, 58.

[0062] As shown in Fig. 4, the roller 64 is not in contact with the rail 54 or any other component of the fixed part 50 unless it is at the level of the locking elements 56, 58. The roller 64 can only come into contact with the locking elements 56, 58. The roller 64 automatically engages the recesses 68 when the roller 64 rolls over the locking elements 56, 58.

[0063] Fig. 3 shows that the locking elements 56, 58 each have a ramp 70 on both sides. When the roller 64 encounters one of the locking elements 56, 58, the roller 64 is pushed back by the respective ramp 70, in particular against the preload pressure, and then engages in the recess 68 of the locking element 56 or 58, in particular under the preload pressure.

[0064] One reason for the two recesses 68 provided in the locking element 58 is that each locking element 56, 58 requires a certain width so that the ramps 70 do not have to be designed too steeply. However, if two locking positions are to be located close to each other, the locking element 58 can be used, which does not require a ramp between the two recesses 68. Instead, a non-inclined section is provided between the two recesses 68 in the locking element 58.

[0065] As shown in Fig. 2, the locking elements 56, 58 are clamped to the rail 54 with screws 72 or threaded pins. The screws 72 can be loosened, and the respective locking element 56 or 58 can be moved along the rail 54 to a desired position and secured there. Additional locking elements can be added by sliding them over the rail 54 and clamping them. By changing the position of one of the locking elements 56, 58, the position of the movable part 52 relative to the stationary part 50 is changed when the roller 64 engages this locking element 56 or 58.

[0066] Another option for precisely positioning the locking position so that the patient support device 22 assumes a specific orientation is to engage the holding element 60 in the corresponding locking element 56, 58 before loosening the screws 72 and then loosen the screws 72. The column 18 is then rotated, and the corresponding locking element 56, 58 moves along the rail 54 with the holding element 60. Once the patient support device 22 is in the desired position, the locking element 56, 58 can be re-fixed in exactly this position with the screws 72.

[0067] The locking elements 56, 58 are arranged along an inner surface of the circular rail 54. The recesses 68 of the locking elements 56, 58 point radially inward within the circle defined by the rail 54. The holding element 60 is arranged radially within the rail 54. The holding element 60 is mounted at an end 74 facing away from the locking end 62 in such a way that it can be rotated or pivoted in the plane defined by the rail 54. Alternatively, it is also possible to design the holding element 60 not to be pivotable about a rotational axis, but rather to mount it via a radially aligned linear guide.

[0068] The spring 66 is mounted on a guide element 76 and exerts a force on the holding element 60 in the direction of the locking elements 56, 58, in this case radially outward. One end of the guide element 76 extends through a recess in the holding element 60 and has an external thread. On the side of the holding element 60 facing away from the spring 66, a nut 78 is screwed onto the external thread of the guide element 76. The nut 78 forms a stop for the holding element 60 and determines the position of the roller 64 when it is not in contact with one of the locking elements 56, 58.

[0069] As shown in particular in Figs. 6 and 7, the base 14 can have a recess or opening on its upper side, which can be closed with a plate 80. When the plate 80 is removed, the recess allows access to the rail 54 and the locking elements 56, 58. If desired, the screws 72 of the locking elements 56, 58 can be loosened and the positions of the locking elements 56, 58 can be changed. Furthermore, additional locking elements can be attached to the rail 54 or locking elements can be removed from the rail 54 through the recess.
