Description

Operating table column

The invention relates to an operating table column having a base body, a tilting body pivotably mounted on the base body about a first pivot axis, and a tilting body pivotally mounted on the tilting body about a second pivot axis. Furthermore, the operating table column has a first actuator for pivoting the inclination body about the first pivot axis and an elongate second actuator for pivoting the edging body about the second pivot axis. A patient support surface can be attached to the edge body in a bearing surface plane. The first actuator is connected to the base body and with the inclination body and the second actuator is pivotally connected to the tilt body in a first connection region and pivotally connected to the edging body in a second connection region.

Before and during surgery of a patient supported on a patient support surface of an operating table, the patient support surface is placed in a position that facilitates engagement with the patient. It may be necessary to pivot the patient support surface at large angles. The height of the patient support surface of the operating table should be adjustable in as large a range as possible. Ideally, the operating table also allows very low heights of the patient support surface, which requires a space-saving design of the operating table column. In addition, individual elements of the patient support surface can often be made from a Be pivoted bearing surface level out to make a fine adjustment of the reclining position of the patient. In general, the actuators provided for pivoting the patient support surface are part of the operating table column, whereas the individual relatively adjustable elements of the patient support surface are adjusted by arranged in the patient support surface actuators.

In hospital operations, three different types of operating tables are commonly used, namely stationary operating tables, movable operating tables and mobile operating tables. Inpatient operating tables have an operating table column fixedly connected to the floor of an operating room, where they usually have no operating table base and are powered by permanently installed cables. The patient support surface is easily detachable and reconnectable in these operating tables and can be moved with a transport device provided for this purpose. With this transport device, a patient can be transported on the patient support surface to and from the operating room.

Movable operating tables have an operating table base connected to the operating table column which allows free positioning in the operating theater and a patient support surface that can be detached and reconnected from the operating table column. The operating table column is moved by means of a column transporter provided for this purpose or, in the case of self-mobile movable operating tables, by means of built-in, extendable transport rollers.

Operating table feet Mobile operating tables have rollers for operating the operating table, so that they can be moved without additional aids and are suitable for transporting a patient. Further, in mobile operating tables, the patient support surface is usually connected to the operating table column and is not released from the operating table column during hospital operation. Both in stationary operating tables as well as movable operating tables and mobile operating tables usually electromotive adjustable components are provided, for example, an electromotively movable in its length operating table column for changing the height of the arranged on the operating table column patient support surface, a two orthogonal axes adjustable operating table column head to change the inclination and the edging of the patient support surface connected to the operating table column head and / or components of the patient support surface which can be adjusted by means of an electric motor.

In the following description, the tilting of the patient support surface about an axis of rotation, which is orthogonal to a vertical plane in which the longitudinal axis of the patient support surface extends, is referred to as inclination. In contrast, tilting of the patient support surface about its longitudinal axis or about an axis of rotation parallel to the longitudinal axis of the patient support surface and lying in a vertical and the longitudinal axis of the patient support surface containing Kantungsebene.

There are known surgical table columns, which have a first linear actuator for tilt adjustment and a second linear actuator for Kantungsverstellung. An example of this is shown in FIGS. 1, 2 and 3.

Figure 1 shows a side view of a surgical table column 10 of the prior art. The operating table column 10 has a main body 12, which comprises three telescopically displaceable column elements 13a, 13b, 13c. In a region 25 at the upper end of the first pillar element 13a, an edging body 14 is arranged. The edging body 14 has a bearing bush 24, in which a not shown and rotatably mounted about a Kantungsachse bolt is received. On a not visible in Figure 1 inclination body 26, a support member 16 is fixed, with which a Kantungszylinder 18 is connected. The canting cylinder 18 comprises a cylinder tube 20 and a piston rod 22, wherein the cylinder tube 20 is pivotally connected at its lower end to the support member 16 and the piston rod 22 is connected at its upper end to the edging body 14. In particular, the canting cylinder 18 is arranged vertically in the illustrated neutral position of the inclination body 26 and the edging body 14.

FIG. 2 shows a perspective view of the operating table column 10 according to FIG. 1. In the region 25 of the column element 13a, the inclination body 26 is pivotably mounted about a first pivot axis AI, which is referred to below as a tilt axis. For this purpose, a firmly connected to the inclination body 26 pivot pin 30 is received in two openings in the area 25 and slidably mounted. About a shown in Figure 3 and connected to a fork 28 lifting cylinder 34, which is referred to below as tilt cylinder, the tilt body 26 is pivoted.

The edging body 14 is pivotally mounted on the inclination body 26 by a pivot pin, which is received in the bearing bush 24 and is not shown in the figures, about a second pivot axis A2, which is referred to below as an inclination axis.

The support element 16 is designed in such a way that the region of the cylinder tube 20 connected to the support element 16 and the region of the piston rod 22 connected to the edging body 14 lie on the same side of a vertical tilting plane passing through the fold axis A2. FIG. 3 is a side view showing the operating table column from a side other than FIG. Here, the tilting cylinder 34 serving for tilt adjustment is visible with its cylinder tube 36 and its piston rod 38. The cylinder tube 36 is pivotally connected to the column member 13 a and the piston rod 38 to the fork 28.

The Kantingzylinder 18 serving for Kantungsverstellung of the edging body 14 is always aligned in the known from the prior art operating table column 10 perpendicular to a bearing surface plane in which a patient support surface can be attached. In particular, the tilting cylinder 18 is mitverschwenkt at a tilt adjustment and requires a lot of space for the pivoting movement. This is disadvantageous in the handling of the operating table column and requires a complex protection of the Kantungszylinders 18 from water and dirt. The protection of the Kantungszylinders 18 is typically realized by a bellows, the wrinkles are very expensive to clean and disinfect. Without such protection, dirt and liquids would penetrate the canting cylinder and contact live components. In addition, the user's hands must be protected from reaching into the pivoting spaces.

It is an object of the invention to provide an operating table column and an operating table, which are simple and compact.

This object is achieved by an operating table column with the features of claim 1 and by an operating table having the features of claim 15. Advantageous developments are specified in the dependent claims. By an operating table column with the features of claim 1 ensures that the second actuator in tilting the inclination body and the edging body less space than claimed in the prior art and easily by a patient support surface from above and a simple structure panel, such as a box-shaped housing of the page can be hidden. As a result, expensive structures such as bellows for covering the second actuator are superfluous. The desired protection of the second actuator is thus easy to ensure over the entire adjustment range. In particular, the cleaning and disinfection simplify.

The inventive arrangement of the elongated second actuator, it is possible to place this just below the edging body. In this case, the longitudinal axis of the second actuator can be arranged so that it preferably includes a small angle with an axis parallel to the first pivot axis, i. is arranged approximately parallel to the bearing surface plane. As a result, the lower end of the second actuator, when pivoting the inclination body, travels a much smaller distance than in the prior art and is not pivoted into the area of action of the user. In particular, the user does not need to be protected from pinching his hands on the second actuator.

In the following, the plane of the bearing surface means a plane which is defined by that part of the patient support surface which is attached to the edging body. In particular, the patient support surface may also have bearing surface parts, for example pivotable leg and / or back plates, which are adjustable relative to the part of the bearing surface mounted on the edging body defining the bearing surface plane. As a first connection region of the second actuator, a first longitudinal end of the elongate second actuator is preferably provided. The second connection region is preferably provided by the second longitudinal end of the second actuator opposite the first longitudinal end.

It is advantageous if the pivotable mounting of the inclination body on the main body and the pivotable mounting of the edging body on the inclination body together form a gimbal bearing of the edging body on the main body. As a result, a high rigidity of the bearing of the edging body is achieved on the body.

It when the pivot axis of the pivotable mounting of the second actuator on the tilt body and the pivot axis of the pivotable mounting of the second actuator on the edging body are parallel to the second pivot axis is particularly advantageous. As a result, decoupling of the tilt adjustment from the tilt adjustment and adjustability of the second adjustment drive in a large angular range are achieved.

Furthermore, it is advantageous if the second actuator is arranged during an adjustment within its adjustment completely below the edging body. As a result, the second actuator is covered from above by the patient support surface. This simplifies the shielding of the second actuator.

Furthermore, it is advantageous if the longitudinal axis of the second actuator encloses an acute angle with the bearing surface plane. As a result, the second actuator is not pivoted so far outwardly from the region of the edging body in a tilt adjustment. It is particularly advantageous if the acute angle is between 5 degrees and 60 degrees. Preferably, the acute angle is between 10 degrees and 50 degrees and ideally between 12 degrees and 25 degrees. The smaller the abovementioned angle, the more compact the shielding of the elongate second actuator can be realized immediately below the patient support surface. The larger this angle is, the more efficiently the force exerted by the second actuator in the direction of its longitudinal axis can be converted into a sufficiently strong torque, which is required for pivoting the edging body.

In a particularly preferred embodiment of the invention, the first actuator and / or the second actuator linear actuators. As a result, the force required for pivoting the edging body is provided with relatively simple technical means. Preferably, the first actuator and / or the second actuator are designed as lifting cylinders.

In an advantageous embodiment, the second actuator is at least partially covered by a rigid cover arranged below the patient support surface. Such a rigid cover is easy to clean and disinfect, and does not hinder the freedom of movement of the user.

Furthermore, it is advantageous if the inclination body has a first bearing bush and a second bearing bush for receiving and for rotatably supporting a rod connected to the edging body, wherein the rod forms the second pivot axis. As a result, the rod transmits an inclination adjustment of the inclination body on the edging body and forms together with the bearing bushes at the same time a pivotable mounting of the edging body about the second pivot axis. By this structure, the edging body is stable and stored in a simple manner on the inclination body. In a further preferred embodiment of the invention, the inclination body has a first projection and a second projection, which are respectively directed to the patient support surface. In this case, the first bearing bush is a first through hole formed in the first protrusion and the second bearing bush is a second through hole formed in the second protrusion. As a result, the distance between the second pivot axis and a patient support surface connected to the edging body is advantageously small. Preferably, this distance is approximately between 1 cm and 6 cm. By this smallest possible selected distance performs the patient support surface at a Kantungsverstellung the smallest possible horizontal movement.

Preferably, a first frame forming the inclination body and a second frame forming the edging body are provided. As a result, a high stability of the inclination body and the edging body and a simple structure are achieved.

In a further advantageous embodiment of the invention, the operating table column has a telescopic structure with at least two relative to each other along a common longitudinal axis displaceable column elements. The inclination body is mounted pivotably on a first of the at least two column elements about the first pivot axis. The first end of the first actuator is pivotally connected to the first column member. As a result, the inclination and the tilt adjustment are decoupled from a height adjustment achievable by the relatively movable column elements. In addition, it is favorable to arrange the first actuator very close to the first column element, since the high forces acting vertically on the first actuator are introduced via short paths into the first column element. Furthermore, it is advantageous if the tilting body is enclosed in a neutral position of the edging body of the edging body in the bearing surface plane and when the first pillar element is enclosed by the tilting body in the bearing surface plane. As a result, the required space in the operating table column is minimized and, with a still large adjustment range, a significantly lower overall height of the operating table column is achieved. A neutral position of the edging body is given in particular when the bearing surface plane is parallel to the cross-sectional area of the inclination body. This is fulfilled, for example, if a patient support surface attached to the edging body is arranged horizontally.

Furthermore, it is advantageous if the first frame and the second frame are rectangular. As a result, a high rigidity of the assembly composed of the edging body and the patient support surface can be achieved.

In a preferred development of the invention, the first pivot axis is perpendicular to the second pivot axis or to an axis parallel to the second pivot axis. Furthermore, the first pivot axis extends through a first side of the edging body and through a second side of the edging body opposite the first side. The second pivot axis extends through a third side of the edging body and through a fourth side of the edging body opposite the third side. As a result, a stable structure is guaranteed, as it knows about from a gimbal storage ago.

Further features and advantages of the invention will become apparent from the following description, which illustrates the invention with reference to embodiments in conjunction with the accompanying figures. Show it: Figure 1 is a side view of a surgical table column of the prior art;

Figure 2 is a detailed perspective view of the operating table column of Figure 1;

Figure 4 is a side perspective view of an operating table column according to an embodiment with parts of the operating table column omitted;

Figure 5 is a perspective view of an operating table with the operating table column shown in Figure 4.

The following description of an exemplary embodiment with reference to FIGS. 4 and 5 makes reference to the embodiment of FIGS. 1 to 3 known from the prior art. Consequently, only those technical aspects are described below in which the exemplary embodiment according to the invention according to FIGS and Figure 5 differs from the embodiment illustrated in Figures 1-3.

FIG. 4 shows a perspective view of an operating table column 80 according to one exemplary embodiment. Elements having the same structure or function as the prior art shown in Figs. 1 to 3 have the same reference numerals. The operating table column 80 has a tilting body 42 pivotally mounted about an inclination axis A3 in the upper region 25 of the first column element 13a and an edging body 40 mounted on the inclining body 42 about an inclination axis A4.

The edging body 40 is connected via a tilting cylinder 50 with the inclination body 42. The tilt cylinder 50 includes a cylinder tube 52 and a piston rod 54 which is slidably received in the cylinder tube 52 in its longitudinal direction. The end of the cylinder tube 52, which is opposite to the protruding from the cylinder tube 52 end of the piston rod 54 is pivotally connected to a support member 53 of the tilt body 42 about a first pivot axis A6. The protruding from the cylinder tube 52 end of the piston rod 54 is pivotally connected to the edging body 40 about a second pivot axis A5. In this case, the end of the cylinder tube 52 connected to the support element 53 is located on one side of a vertical Kantungsebene containing the Kantungsachse A4 and connected to the edging body 40 end of the piston rod 54 on the other side of the Kantungsebene.

The ends of the Kantungszylinders 50 remain at an adjustment of the Kantungszylinders 50 and / or an adjustment of the tilting cylinder 34 each within its adjustment on its respective side of the Kantungsebene. In this case, the longitudinal axis of the tilting cylinder 50 encloses an acute angle with the bearing surface plane which is parallel to a plane defined by the bearing surface 41 of the edging body 40. The tilting cylinder 50 is arranged approximately parallel to the bearing surface plane below the patient support surface 58 over its entire adjustment range. The canting cylinder 50 is thus covered by pivoting the inclination body 42 and the edging body 40 upwardly through the patient support surface 58. The cylinder tube 36 of the tilt cylinder 34 is connected to the first pillar member 13a via a bolt, not shown. In contrast to the operating table column 10 illustrated in FIGS. 1 to 3, the piston rod 38 of the tilting cylinder 34 is pivotably connected to a lug 39, which in turn is pivotally coupled to the tilting body 42.

In the upper region of the pillar element 13a, a first bearing bush 43a and a second bearing bush not visible in the perspective shown in FIG. 4 are formed. In this bearing bushes 43 a each a pivot pin is received, about which the inclination body 42 is rotatably mounted. The pivot axis defined by the pivot pins forms the tilt axis A3 of the tilt body 42.

The inclination body 42 has a first projection 45 and a second projection 47, both of which are directed upward and in which a third bearing bush 44 and a fourth bearing bush 46 is formed as a through hole.

In which the inclination body 42 in a plane parallel to the bearing surface plane enclosing the edge body 40, a first, lying on the Kantungsachse A4 through hole 48 and a second, not visible in Fig. 4 through hole is formed. In these through holes 48 and the bearing bushes 44, 46 a not shown in Fig. 4 rod is received, which forms the Kantungsachse A4. The rod is fixedly connected to the through holes 48 and rotatably supported in the third and the fourth bearing bush 44, 46. Furthermore, a vertical force intended for height adjustment of the first column element 13a is introduced on this rod. The necessary actuator is not shown. The tilt cylinder 34 and the base body 12 are partially covered by a cover 56 shown only schematically in FIG. The tilt cylinder 34 is guided through a slot 57 of the cover 56.

FIG. 5 shows a perspective view of an operating table with the operating table column 80 shown in FIG. 4. Below the patient support surface 58, a rigid box 70, in which the tilting cylinder 50 is accommodated, is arranged parallel to the bearing surface plane and connected to the edging body 40. As a result, the Kantungszylinder 50 laterally and down box 70 is protected against external influences. The pillar elements 13a to 13c are protected by a further cover 72, which is arranged above the cover 56. The cover 56 sits on a pedestal 74.

The patient support surface 58 has a plurality of mutually pivotable segments, of which in Fig. 5, only two segments are shown.
