Description

The invention relates to an operating table with an operating table column and a patient support surface arranged on the operating table column.

Operating tables with an operating table column and a patient support surface arranged on the operating table column are known from the prior art. In these known operating tables, the operating table column is provided with a column cladding.

Figure 5 shows a perspective view of an operating table 100 according to the prior art. As in Figure 5 As shown, the known operating table 100 comprises a patient support surface 102 which is arranged above an operating table column 104 provided with a column cladding. Furthermore, in Figure 5 It is shown that the operating table column 104 is arranged on an operating table base 106. The patient support surface 102 comprises a first to third support surface section 110 to 114. The operating table column 104 comprises four components 116a to 116d of the column cladding arranged one above the other. An operating component 118 and a bellows 120 are provided between the upper component 116d of the four components 116a to 116d arranged one above the other and the patient support surface 102. The bellows 120 is integrated into the head part of the operating table column 104. The operating table base 106 comprises several swivel castors 108. The bellows 120 integrated in the head part of the operating table column 104 is used to laterally cover movable parts of the operating table 100 that run inside the operating table column 104. In particular, these moving parts of the operating table 100 include energy-carrying lines for supplying the patient bed 102 with energy.

Figure 6 shows a perspective view of an operating table 200 according to the prior art. As in Figure 6 As shown, the known operating table 200 comprises a patient support surface 202 which is arranged above an operating table column 204 provided with a column cladding. Furthermore, in Figure 6 It is shown that the operating table column 204 is arranged on an operating table foot 206. The patient support surface 202 comprises a first and second support surface section 208, 212. The first support surface section 208 of the patient support surface 202 comprises a back plate 210, while the second support surface section 212 of the patient support surface 202 comprises a base plate 214. The operating table column 204 comprises four components 216a to 216d of the column cladding arranged one above the other. The upper component 216d of the four components 216a to 216d arranged one above the other comprises an operating component 218. Furthermore, a bellows 220 is provided between the upper component 216d of the four superposed components 216a to 216d and the patient support surface 202. The bellows 220 is integrated into the head part of the operating table column 204. The bellows 220 integrated in the head part of the operating table column 204 is used to laterally cover moving parts of the operating table 200 that run inside the operating table column 204. In particular, these moving parts of the operating table 200 include energy-carrying lines for supplying the patient bed 202 with energy.

The in Figure 5 and 6 Operating tables 100, 200 shown according to the prior art, a bellows 120, 220 is thus used. As in Figure 5 and 6 As shown, this bellows 120, 220 is provided in particular between the patient support surface 102, 202 and the upper component 116d, 216d of the column cladding.

The known operating tables have the disadvantage that their construction is relatively complicated and expensive due to the use of a bellows provided between the patient support surface and the upper component of the column cladding.

Furthermore, the cleaning of the folds of the bellows is relatively laborious when the operating table is operating.

The U.S. 3,206,188 A concerns an operating table. On the basis of the known prior art, it is the object of the invention to provide an operating table which has a simple structure and which enables simple maintenance of the same during operation.

This object is achieved by an operating table with the features of claim 1. Advantageous further developments are given in the dependent claims.

An operating table with the features of claim 1 achieves a simple structure and easy maintenance of the same during operation, since in particular the operating table column comprises a column cladding with at least two rigid components arranged one above the other. The operating table column is designed in such a way that all moving parts of the operating table running inside the operating table column are completely covered laterally. Furthermore, an intermediate space extends from the upper edge of the two stacked components of the column cladding to the patient support surface, the intermediate space being a space free of bellows. The use of a bellows provided between the patient bed and the upper component of the column cladding can thus be avoided. Furthermore, the relatively cumbersome cleaning of the folds of the bellows when the operating table is in operation is no longer necessary. This enables simple construction and simple maintenance of the operating table in the operating theater.

The operating table column is preferably designed in such a way that sections of the movable parts which extend from an upper edge of the two stacked components of the column cladding to the patient bed, are not covered by a bellows at the side. The disadvantages of the prior art mentioned in connection with the known operating tables can thus be avoided.

Preferably, sections of the movable parts that extend from the upper edge of the two stacked components of the column cladding to the patient support surface are at least partially covered laterally by a first and second rigid head part element of the operating table column and / or a first and second rigid side rail of the patient support surface. Thus, these sections of the movable parts can only be covered laterally by rigid head part elements of the operating table column or rigid side rails of the patient support surface. Thus, instead of the bellows used in the prior art, non-foldable components can be used to laterally cover these sections of the moving parts.

Preferably, an upper component of the two stacked components of the pillar cladding is dome-shaped. Thus, a relatively large adjustment range of the patient support surface can be provided when the same is inclined about an axis of inclination.

The upper component of the two stacked components of the column cladding preferably comprises at least two side walls which are at least partially inclined in the direction of the interior of the operating table column. It can thus be avoided that the patient support surface, when it is inclined about the axis of inclination, hits the upper component of the two components of the column cladding that are arranged one above the other too quickly.

The side walls of the upper component which are inclined in the direction of the interior of the operating table column are preferably two side walls lying opposite one another. The two opposing side walls of the upper component include a front side wall with respect to a first direction parallel to the longitudinal direction of the patient support surface and a rear side wall with respect to the first direction parallel to the longitudinal direction of the patient support surface. Thus, with respect to the first direction parallel to the longitudinal direction of the patient support surface, front and rear side walls, each inclined in the direction of the interior of the operating table column, can be provided. With the aid of these front and rear side walls, the relatively large adjustment range of the patient support surface can be obtained when the same is tilted.

Preferably, a lower component of the two stacked components of the column cladding comprises at least two side walls which are at least partially inclined in the direction of the interior of the operating table column. In this way, it can be avoided that the patient support surface, when it is tilted about an axis of tilt, hits the lower component of the two components of the column cladding that are arranged one above the other too quickly.

The side walls of the lower component, which are inclined in the direction of the interior of the operating table column, are preferably two side walls lying opposite one another. The two opposing side walls of the lower component include a front side wall in relation to a second direction parallel to the transverse direction of the patient support surface and a rear side wall in relation to the second direction parallel to the transverse direction of the patient support surface. Thus, with respect to the second direction parallel to the transverse direction of the patient support surface, front and rear side walls, each inclined towards the interior of the operating table column, can be provided. As a result, a relatively large adjustment range of the patient support surface can be obtained when the same is tilted about a tilt axis.

The column cladding is preferably designed in such a way that it can be separated into two halves along a dividing line which runs essentially in the direction of stroke movement of the patient support surface through the two components of the column cladding arranged one above the other. A simple separation of the two halves of the pillar cladding can thus be achieved. As a result, the moving parts of the operating table running within the operating table column can be easily serviced.

The pillar cladding preferably comprises at least one half-shell-shaped housing element integrated in a side wall of a lower component of the two stacked components of the pillar cladding for receiving an IR (infrared) receiver. The half-shell-shaped housing element is attached to the side wall of the lower component without screws. It is thus possible to simply attach the half-shell-shaped housing element to the side wall of the lower component or to simply separate it from the side wall of the lower component.

The pillar cladding preferably comprises two halves which can be connected to one another and which, in the connected state, form the two components of the pillar cladding arranged one above the other. Thus, instead of a single pillar trim part, two halves of the pillar trim that can be connected to one another can be provided.

Preferably, the pillar trim comprises a tongue and groove arrangement for connecting the two halves of the pillar trim. A simple and secure connection of the two halves of the pillar cladding can thus be achieved.

The column cladding preferably comprises an opening for the passage of an inclination cylinder coupled to the patient support surface. Here is the opening provided with a sealing element. Furthermore, the sealing element is designed such that the opening is completely sealed in every position of the tilt cylinder. Damaged components of the two stacked components of the column cladding can thus be replaced without dismantling the tilt cylinder.

The patient support surface can preferably be rotated about an axis of inclination with a first angle of rotation greater than 20 ° in a positive and negative direction of rotation and / or about an axis of inclination with a second angle of rotation greater than 15 ° in the positive and negative direction of rotation. The first angle of rotation and the second angle of rotation are related to an initial position of the patient support surface. Thus, a relatively high adjustment performance of the patient support surface can be achieved in the case of a tilting movement or a tilting movement of the same in relation to an initial position of the patient support surface.

Preferably, the two stacked components of the pillar cladding are made of plastic. Thus, a suitable material can be used for the pillar cladding. Furthermore, the pillar cladding can thereby be cleaned easily.

Further features and advantages of the invention emerge from the following description, which explains the invention in more detail on the basis of exemplary embodiments in connection with the accompanying figures.

Figure 1 shows a perspective view of an operating table 10 with an operating table column 14 provided with a column cladding 40 according to an embodiment of the present invention. As in Figure 1 As shown, the operating table 10 comprises a patient support surface 12 which is arranged on the operating table column 14. Furthermore, the operating table column 14 is arranged on the operating table base 20. The patient support surface 12 comprises a first and second support surface section 22, 26. The first support surface section 22 of the patient support surface 12 comprises a back plate 24, while the second support surface section 26 of the patient support surface 12 comprises a base plate 28.

Furthermore, the patient support surface 12 comprises first and second rigid side rails 34, 36.

Furthermore, in Figure 1 shown that the patient support surface 12 is rotatable about an inclination axis 18 with a first angle of rotation α and / or about an incline axis 16 with a second angle of rotation β. The tilt axis 16 runs parallel to a first direction 30, which is parallel to the longitudinal direction of the patient support surface 12, while the inclination axis 18 runs parallel to a second direction 32, which is parallel to the transverse direction of the patient support surface 12. Furthermore, the tilt axis 16 runs essentially centrally through the back plate 24 and the base plate 28, while the inclination axis 18 runs essentially centrally through the base plate 28.

The first angle of rotation α is preferably greater than 20 °, while the second angle of rotation β is greater than 15 °. The first angle of rotation α and the second angle of rotation β are set to in Figure 1 The starting position shown is related to the patient support surface 12. Furthermore, the first angle of rotation α and the second angle of rotation β each correspond to a rotation of the patient support surface 12 in a positive or negative direction of rotation. The adjustment performance of the in Figure 1 patient support surface 12 shown is relatively high.

In the Figure 1 The operating table column 14 shown serves to completely laterally cover all movable parts 38 of the operating table 10 that run inside the operating table column 14. These movable parts 38 of the operating table 10 preferably comprise energy-carrying lines for supplying the patient support surface 12 with energy. The energy-carrying lines are in Figure 1 shown schematically by dashed lines. For example, the energy-carrying lines include electrical and / or hydraulic lines.

The in Figure 1 The embodiment shown, the column cladding 40 comprises two superposed, rigid components 42a, 42b. These two components 42a, 42b of the pillar cladding 40 are preferably made of plastic. As in Figure 1 As shown, the patient support surface 12 is disposed on the upper component 42 a of the column lining 40. Furthermore, the upper component 42a of the pillar trim 40 is arranged on the lower component 42b of the pillar trim 40. Furthermore, in Figure 1 It is shown that the upper component 42a of the column cladding 40 comprises two side walls 46a, 46b inclined in the direction of the interior of the operating table column 14. These side walls 46a, 46b of the upper component 42a are preferably two mutually opposite side walls which comprise a side wall 46a which is front in relation to the first direction 30 and a side wall 46b which is rear in relation to the first direction 30.

Also includes according to Figure 1 the lower component 42b of the column cladding 40 has two side walls 48a, 48b inclined in the direction of the interior of the operating table column 14. Preferably, these side walls 48a, 48b of the lower component 42b are two opposing side walls, one with respect to the second direction 32 front side wall 48a and a rear side wall 48b with respect to the second direction 32.

The in Figure 1 The illustrated embodiment shows a dividing line 50 for separating the pillar cladding 40, which runs through the upper component 42a and the lower component 42b of the pillar cladding 40. Furthermore, in Figure 1 a half-shell-shaped housing element 56 integrated in the lower component 42b of the pillar cladding 40 is shown. This half-shell-shaped housing element 56 is used to accommodate an IR receiver for controlling the operating table 10.

Figure 2 FIG. 11 shows a front view of the operating table 10 according to FIG Figure 1 . In Figure 2 are essentially components 12 to 56 of in Figure 1 operating table 10 shown. Furthermore, in Figure 2 a stroke movement direction P of the patient support surface 12 is shown. The direction of stroke movement P runs essentially perpendicular to the patient support surface 12 in which is in its starting position Figure 2 a front side wall 46c with respect to the second direction 32 and a rear side wall 46d with respect to the second direction 32 of the upper 42a of the pillar trim 40 are clearly visible. Furthermore, in Figure 2 a front side wall 48c of the lower component 42b of the pillar trim 40, which is front relative to the first direction 30, is clearly visible. According to Figure 2 the half-shell-shaped housing element 56 is attached to this side wall 48c.

As in Figure 2 Shown schematically, portions 39 of the movable parts 38 of the operating table 10 extend through a bellows-free interspace 66. This bellows-free interspace 66 extends from an upper edge 44 of the upper component 42a of the column cladding 40 to the patient support surface 12. Preferably, the in Figure 2 Sections 39 shown of the moving parts 38 energy-carrying line sections. These line sections serve in particular for supplying the side rails 34, 36 of the patient bed 12 with energy.

In Figure 2 a first head part element 68a of the operating table column 14 is shown by a dashed line. Furthermore, in Figure 2 a second head part element 68b of the operating table column 14 is clearly visible. The first and second head part elements 68a, 68b preferably form a cardan joint for the cardanic mounting of the patient support surface 12 Figure 2 the sections 39 of the movable parts 38 extending through the intermediate space 66 are laterally covered by the first and second head part elements 68a, 68b and the first and second side rails 34, 36 of the patient support surface 12. Both the first and second head part elements 68a, 68b and the first and second side struts 34, 36 represent rigid components. Thus, lateral covering of the line sections 39 running through the space 66 can only be achieved by using rigid components. The use of a bellows is not required. Furthermore, the lateral covering of the line sections 39 running through the space 66 can also be achieved if the first and second side rails 34, 36 or the first and second head part elements 68a, 68b are omitted.

According to Figure 2 the column cladding 40 comprises an opening 60 provided with a sealing element 62. This opening 60 is used to pass through an inclination cylinder 64 coupled to the patient support surface 12. Furthermore, the sealing element 62 serves to completely seal the opening 60 in every position of the inclination cylinder 64. The inclination movement of the patient support surface 12 can be implemented with the aid of the inclination cylinder 64. As in Figure 2 As shown, the tilt cylinder 64 extends at least partially outside of the pillar cladding 40 Figure 2 tilt cylinder 64 shown is in FIG Figure 1 not shown.

Figure 3 shows a side view of the operating table according to FIG Figure 1 . In Figure 3 are essentially the in Figure 1 and 2 Components 12 to 56 and 12 to 64 of the operating table 10 shown are shown. Furthermore, in Figure 3 a rear side wall 48d of the lower component 42b of the pillar cladding 40, which is rearward with respect to the first direction 30, is clearly visible. As in Figure 3 In addition to the half-shell-shaped housing element 56 which is attached to the front side wall 48c of the lower component 42b with respect to the first direction 30, a further half-shell-shaped housing element 58 is attached to the rear side wall 48d of the lower component 42b with respect to the first direction 30. This further half-shell-shaped housing element 58 serves to accommodate a further IR receiver for controlling the operating table 10.

Furthermore, in Figure 3 the dividing line 50 provided in the pillar cladding 40 is clearly visible. In the Figure 3 The dividing line 50 shown serves to separate the pillar cladding 40 along the same into two halves 52a, 52b. The dividing line 50 runs essentially in the direction of stroke P of the patient support surface 12 through the upper component 42a and the lower component 42b of the column cladding 40. The two halves 52a, 52b of the column cladding 40 can preferably be connected to one another with the aid of a tongue and groove arrangement 54. In Figure 3 this tongue and groove arrangement 54 is shown schematically. Preferably, the tongue and groove arrangement 54 is provided in the lower component 42b of the pillar trim 40. With the aid of this tongue and groove arrangement 54, the two halves 52a, 52b of the pillar cladding 40 can be connected to one another easily and securely.

Figure 4a FIG. 11 shows a perspective view of one in the column cladding 40 of the operating table 10 according to FIG Figure 1 integrated, half-shell-shaped housing element 56 for receiving an IR receiver 70. The in Figure 4a The housing element 56 shown with the IR receiver 70 is provided in the lower component 42b of the column cladding 40. This housing element 56 is preferably on the Side wall 48c of lower component 42b attached without screws. This is based on Figure 2 and 4a clarified. Furthermore, in Figure 4a an inner column member 72 of the operating table column 14 is shown. Preferably, this inner column member 72 comprises steel. The in Figure 4a The IR receiver 70 shown comprises, for example, a plurality of sensors for the detection of assigned IR signals. With the aid of these IR signals detected by the sensors, various functions of the operating table 10 can be controlled during the operation. Furthermore, this is in Figure 4a Housing element 56 shown is transparent to IR radiation.

Figure 4b FIG. 11 shows a schematic sectional view to illustrate one on the operating table column 14 of the operating table 10 according to FIG Figure 1 arranged first pin element 76a for the rotatable mounting of the column cladding 40. In particular, in Figure 4b a schematic sectional illustration of the half 52b of the pillar cladding 40 in the viewing direction opposite to the second direction 32 is shown. Figure 4c shows a further schematic sectional illustration to illustrate the first pin element 76a shown in FIG. 4b. In particular, in Figure 4c A further schematic sectional illustration of half 52b of pillar cladding 40 is shown in the viewing direction opposite to first direction 30. According to Figures 4b and 4c the half 52b of the pillar cladding 40 comprises the side walls 46a and 46c, respectively. Furthermore, according to Figures 4b and 4c the first pin member 76a is arranged below the side wall 46c. This in Figures 4b and 4c The first pin element 76a shown is provided on an inner column element 74a of the operating table column 14. In Figure 4b In particular, the inner column element 74a is not shown.

Figure 4d FIG. 11 shows a schematic sectional view to illustrate one on the operating table column 14 of the operating table 10 according to FIG Figure 1 arranged second pin element 76b for the rotatable mounting of the column cladding 40. In particular, in Figure 4d a schematic sectional view of half 52b of pillar cladding 40 in second direction 32 is shown as a viewing direction. Figure 4e shows a further schematic sectional view to illustrate the second pin element 76b shown in Figure 4d. In particular, in Figure 4e A further schematic sectional illustration of half 52b of pillar cladding 40 is shown in the viewing direction opposite to first direction 30. According to Figures 4d and 4e half 52b of pillar cladding 40 includes side walls 46a and 46d, respectively. Furthermore, according to Figures 4d and 4e the second trunnion element 76b is arranged below the side wall 46d. This in Figures 4d and 4e The second pin element 76b shown is provided on an inner column element 74b of the operating table column 14. In Figure 4d In particular, the inner column element 74b is not shown.

This in Figures 4b to 4e The first and second pin elements 76a, 76b shown each serve for the rotatable mounting of the column cladding 40. As in FIG Figures 4b to 4e Shown schematically, in particular the half 52b of the pillar cladding 40 is rotatable with the aid of the first and second pin elements 76a, 76b about a common axis of rotation 78 with a third angle of rotation γ. According to Figures 4b to 4e the axis of rotation 78 runs essentially parallel to that in FIG Figure 1 inclination axis 18 shown through the center of the first and second pin elements 76a, 76b. The third angle of rotation γ is preferably less than or equal to 5 °. The third angle of rotation γ is based on an initial position of the column cladding 40.

According to Figures 4b to 4e the half 52b of the pillar cladding 40 can be slipped onto the first and second pin elements 76a, 76b. Furthermore, the in Figure 3 The half 52a of the pillar cladding 40 shown, for example by means of a screw, is fixed to the in Figures 4b to 4e half 52b of the column cladding 40 shown are connected. In this case, the two halves 52a, 52b of the pillar cladding 40 form a coherent unit which is rotatably mounted on the first and second pin elements 76a, 76b.

The first and second pin elements 76a, 76b are preferably arranged symmetrically below the two opposite sides 46c, 46d of the upper component 42a of the pillar trim 40. That is to say, the first and second pin elements 76a, 76b are two elements lying opposite one another, through whose centers the common axis of rotation 78 runs.

Based on Figures 4b to 4e a rotatable mounting of the column cladding 40 is thus illustrated. A first and second cylindrical pin element 76a, 76b are preferably attached to the operating table column 14. Opposite depressions 80a, 80b are provided on the inside of the side walls 46c, 46d. The first and second pin elements 76a, 76b engage in these recesses 80a, 80b. By sliding on and connecting the halves 52a, 52b of the pillar cladding 40, the coherent unit can be formed, so that the pillar cladding 40 can be rotated, preferably for angles of rotation of up to approx Operating table column 14 can be attached. If the patient support surface 12 or other elements attached above the column cladding 40 collide with the column cladding 40 due to a malfunction, the column cladding 40 can move movably with the help of the rotatable mounting. In particular, this prevents the pillar cladding 40 from being destroyed by overloading. When the pillar cladding 40 moves, the user recognizes the malfunction and can stop the movement.

The present invention has the advantage over the known prior art that no bellows is required. In particular, this eliminates the need to clean the folds of a bellows during surgery.

The operating table 10 according to the present invention is characterized by high adjustment performance of the patient support surface 12. Preferably are a tilt movement the patient support surface 12 with an angle of inclination greater than 20 ° and a tilting movement of the patient support surface 12 with an angle of inclination greater than 15 °. In the operating table 10 according to the invention, drives and load-bearing components can be protected by the column cladding 40. This prevents liquids from entering the drives and, for example, controls and users being able to reach into the moving drives. Furthermore, pinch and shear points can be covered with the help of the pillar cladding 40. In contrast to the known prior art, the intermediate space 66 containing the sections 39 of the movable parts 38 does not have to be laterally covered by a bellows.

According to the present invention, the patient support surface 12 is arranged on the operating table column 14. Furthermore, the drive rod of the tilt cylinder 64 is coupled to the patient support surface 12 in such a way that an opening 60 with a sealing element 62 can be made in the column cladding 40. With the help of this opening 60, it is possible to replace damaged components of the column cladding 40 without dismantling the drive rod of the tilt cylinder 64. The half 52a of the pillar cladding 40 is for example in Figure 3 deducted to the left. Further, the half 52b of the pillar trim 40 in FIG Figure 3 can be deducted to the right. At the dividing line 50 between the half 52a and the half 52b is the in Figure 3 illustrated tongue / groove arrangement 54 is provided.

Preferably, the halves 52a, 52b of the pillar cladding 40 are floatingly mounted on fixed elements. In the event of an unintentional collision of the patient support surface 12 with the halves 52a, 52b of the column cladding 40, these can evade by up to 15mm, so that damage to the column cover 40 or the colliding components of the patient support surface 12 can be avoided. This collision occurs in particular in the event of a monitoring error. The user can respond to the fault by elastic deformation of the column cladding 40 be made aware. He then has enough time to stop the adjusted function before permanent damage occurs.

The infrared-permeable housing element 58 or 56 is embedded in at least one of the two halves 52a, 52b of the column cladding 40. With the aid of this housing element 58, 56, data communication via infrared is easily possible. The simple dismantling by pulling off the two halves 52a, 52b of the pillar cladding 40 in Figure 3 To the left and right, a technician can simply maintain the elements below. In contrast to the known prior art, no external screws have to be loosened so that the half-shell-shaped, infrared-permeable housing element 56 or 58 can be removed. In particular, no extensive detachable seals are necessary. Furthermore, the cleaning is not disturbed by screws. In the operating table 10 according to the invention, the housing element 58 is firmly integrated into the half 52a of the column cladding 40, while the housing element 56 is permanently integrated into the half 52b of the column cladding 40. Housing member 56, 58 should be attached to side wall 48c and 48d, respectively. It should not be attached to the side wall 48a containing a control panel, since it would disturb a user standing to one side there.

According to exemplary embodiments, the components 42a, 42b of the pillar cladding 40 are made from inexpensive plastic. Thus, the complex welded assemblies made of stainless steel known from the prior art can be dispensed with. The arrangement of the dome-shaped upper component 42a of the column cladding 40 between the side bars 34, 36 of the patient support surface 12 means that the bellows according to the prior art can be avoided. The roof effect of the patient support surface 12 prevents the penetration of liquids which usually drip from above, ie from the patient support surface 12. The dome-shaped upper component 42a is fixed to the lower component 42b of the column cladding 40 is connected. The dividing line 50 runs through both the upper component 42a and the lower component 42b. With the help of the pillar cladding 40, all movable machine parts can be attached inside the operating table 10 in such a way that the user is not injured. By skillfully rounding off or beveling the column cladding 40 made of plastic, the cleaning of the operating table 10 can be facilitated and the adjustment range of the patient support surface 12 can be increased.
