Abstract

The invention relates to an operating table, in particular for emergency surgery. The table tops of the known tables can be raised and lowered, and in addition can be tilted about an axis, which extends parallel to the table top and parallel to the narrow edge of the table top. In a great many cases, these movement possibilities are insufficient for bringing the body into the position most suitable for the operation. The invention therefore proposes designing the operating table in such a way that the table top can be tilted about an axis extending parallel to its longitudinal axis and can be turned about an axis extending perpendicular to it. <IMAGE>

Description

Die Erfindung betrifft einen Operationstisch, insbeson­dere zur Versorgung Unfallverletzter. Für diesen Zweck sind Operationstische bekannt, bei denen eine Tisch­platte auf eines teleskopartig verlängerbaren und ver­kürzbaren Säule anhebbar und absenkbar angeordnet ist. Die Säule kann stationär auf dem Fussboden eines Opera­tionssaales befestigt oder auf einem Fahrgestell ange­ordnet sein. Zusätzlich zu der Möglichkeit des anhebens und absenkens der Tischplatte ist es auch bekannt, diese um eine Achse zu kippen, die parallel zur Tischplatte und parallel zur schmalen Kante der Tischplatte verläuft. Aus der GB-A-481 836 ist es darüberhinaus bekannt, einen Operationstisch so auszubilden, dass seine Tischplatte sowohl um eine parallel zur schmalen Kante als auch um eine parallel zur Längsachse der Tischplatte verlaufen­de Achse kippbar ist. Die Bewegungsmöglichkeiten reichen jedoch nicht aus, um den Körper des Unfallverletzten in die bei häufigen Operationen erforderliche Position zu bringen. Insbesondere ist die Nagelung des Oberschen­kels nur unter Schwierigkeiten möglich, es muss sogar inkauf genommen werden, dass zur Anbringung einer Draht­extension der Oberschenkel in Kniegelenksnähe durchbohrt werden muss. Schliesslich ist die Bruchstelle in vielen Fällen für das zur Überwachung der Operation erforder­liche Röntgenbildverstärkergerät nur schlecht zugänglich.The invention relates to an operating table, in particular for the care of accident victims. For this purpose, operating tables are known in which a table top can be raised and lowered on a telescopically extendable and shortenable column. The column can be fixed stationary on the floor of an operating room or arranged on a chassis. In addition to the possibility of raising and lowering the table top, it is also known to tilt it around an axis that runs parallel to the table top and parallel to the narrow edge of the table top. From GB-A-481 836 it is also known to design an operating table in such a way that its table top can be tilted both about an axis parallel to the narrow edge and about an axis running parallel to the longitudinal axis of the table top. However, the range of motion is insufficient to bring the body of the accident victim into the position required for frequent operations. In particular, nailing the thigh is only possible with difficulty, it must even be accepted that the thigh must be drilled near the knee joint in order to attach a wire extension. Finally, in many cases the fracture site is difficult to access for the X-ray image intensifier required to monitor the operation.

Ausserdem weisen die bekannten Tische zahlreiche weitere Mängel auf, zu denen insbesondere eine not­wendig grosse Länge der Holme gehört, so dass diese bei Nichtgebrauch des Tisches unnötig viel Platz weg­nehmen.In addition, the known tables have numerous other defects, including in particular a necessary length of the bars, so that they take up unnecessarily much space when the table is not in use.

Diese Nachteile werden durch den Operationstisch gemäss der Erfindung vermieden.These disadvantages are avoided by the operating table according to the invention.

Gegenstand der Erfindung ist ein Operationstisch insbesondere zur Versorgung Unfallverletzter, dessen Tischplatte um eine zu ihrer Längsachse parallel verlaufende Achse kippbar und um eine senkrecht zu ihr verlaufende Achse drehbar ist, wobei die Kippachse unterhalb der Tischplatte in einem bestand von ihr verläuft und der dadurch gekennzeichnet ist, dass ein Drehgelenk zur Drehung der Tischplatte um die senkrecht zu ihr verlaufende Achse im Bereich zwischen der Kippachse und der Tischplatte angeordnet ist.The invention relates to an operating table, in particular for the care of accident victims, the table top of which can be tilted about an axis running parallel to its longitudinal axis and rotatable about an axis running perpendicular to it, the tilting axis running underneath the table top and being characterized by it that a swivel joint for rotating the table top about the axis perpendicular to it is arranged in the area between the tilt axis and the table top.

Bei dem Operationstisch gemäss der Erfindung lässt sich durch eine Kippbewegung um die X-Achse und gleichzei­tiges Drehen des Tisches um die Z-Achse eine Körperposi­tion herstellen, in der der Oberschenkel leicht zur Na­gelung erreichbar und gleichzeitig für den Bildverstär­ker gut und aus allen Richtungen zugänglich bleibt.In the operating table according to the invention, a tilting movement about the X axis and simultaneous rotation of the table about the Z axis can produce a body position in which the thigh is easily accessible for nailing and at the same time remains well accessible to the image intensifier and from all directions .

Die Kippachse verläuft unterhalb der Tischplatte in einem Abstand von dieser und das Drehgelenk ist zwischen der Kippachse und der Tischplattz angeordnet. Bei dieser Ausbildung lässt sich eine geringe Bauhöhe der die beiden genannten Bewegungen duchführenden Getriebe erreichen und die zum Antrieb der Getriebe dienenden Wellen bleiben bei allen Stellungen des Tisches leicht zugänglich.The tilt axis runs below the table top at a distance from it and the swivel joint is arranged between the tilt axis and the table top. With this design, a low overall height of the gears carrying out the two movements mentioned can be achieved and the shafts serving to drive the gears remain easily accessible in all positions of the table.

Bei einer bevorzugten Ausführungsform des Tisches gemäss der Erfindung ist ein Fahrgestell vorhanden, das zwei parallel zueinander verlaufende Holme und zwei in einem Winkel zueinander verlaufende Holme aufweist. Hierdurch ist es möglich, die Stabilität des Tisches erheblich zu verbessern. Insbesondere dann, wenn die parallel zuein­ander verlaufenden Holme zum Kopfende der Tischplatte und deshalb die in einem Winkel zueinander verlaufenden Holme zum Fussende der Tischplatte hinweisen, lässt sich die begrenzte Verdrehbarkeit der Tischplatte um die Z­Achse so einstellen, dass der Drehbereich oberhalb der beiden winklig zueinander verlaufenden Holme endet, so dass eine instabile Lage, auch bei schwergewichtigen Patienten nicht erreicht werden kann. Weiterhin ist es zweckmässig, die Lenkrollen an den Enden der parallel zueinander verlaufenden Holme, also am Kopfende des Tisches anzuordnen, damit das Fussende des Tisches be­sonders stabil mit dem Boden verbunden ist.In a preferred embodiment of the table according to the invention there is a chassis which has two spars running parallel to one another and two spars running at an angle to one another. Hereby it is possible to significantly improve the stability of the table. Especially when the parallel bars to the head end of the table top and therefore the bars at an angle to the foot end of the table top indicate, the limited rotatability of the table top around the Z-axis can be adjusted so that the range of rotation above the two is at an angle to each other Holme ends, so that an unstable position cannot be reached, even with heavy patients. Furthermore, it is expedient to arrange the castors at the ends of the parallel bars, that is, at the head end of the table, so that the foot end of the table is connected to the floor in a particularly stable manner.

Von besonderem Vorteil ist weiterhin, dass unter der Tischplatte ein parallel zu dieser und in Querrichtung der Tischplatte verfahrbarer Schlitten angeordnet ist, an dessen zu den Längskanten der Tischplatte weisenden Enden Armstrecken anbringbar sind. Auf diese Weise las­sen sich Armoperationen durchführen, ohne dass die bis­her erforderlichen Zusatzteile am Tisch angebracht wer­den müssen. Ausserdem lässt sich infolge der Verfahrbar­keit des Schlittens die Armstrecke den Körpermassen des Patienten anpasse und schliesslich ist auf leichte Weise ein Einrichten des Oberarmbruches möglich. Wenn, was weiterhin bevorzugt ist, die Armstrecke um parallel zu den Längskanten der Tischplatte verlaufende Achsen schwenkbar und arretierbar ist, so kann durch Herahb­schwenken dieses den Unterarm aufnehmenden Teiles die­ser herabhängen und anschliessend zur Behandlung des Unterarmes hochgeschwenkt werden.It is also of particular advantage that a slide which can be moved parallel to this and in the transverse direction of the table top is arranged under the table top, and arm sections can be attached to the ends thereof pointing towards the longitudinal edges of the table top. In this way, arm operations can be performed without having to attach the previously required additional parts to the table. In addition, due to the movability of the sled, the arm distance can be adapted to the body mass of the patient and finally the upper arm fracture can be easily set up. If, which is further preferred, the arm section can be pivoted and locked about axes running parallel to the longitudinal edges of the table top, then the part receiving the forearm can hang down by swiveling it down and then swung up to treat the forearm.

Von besonderem Vorteil ist eine zur Aufnahme der Beine des Patienten dienende Holmanordnung, deren Holme um je eine senhkrecht zur Tischplatte verlaufende Achse und um je eine parallel zur schmalen Kante der Tischplatte verlaufende Achse schwenkbar sind. Bei die­ser Holmanordnung kann man die Holme leicht und ohne Verwendung von Zusatzteilen an die jeweils gewünschte Beinstellung anpassen. Auf den Holmen sind Extensions­schlitten verschiebbar und arretierbar angeordnet. An diese Extensionsschlitten können Fusshalter herkömm­licher Bauart ohne Zuhilfenahme von Verlängerungen ange­bracht werden.Of particular advantage is a spar arrangement used to hold the patient's legs, the spars of which can be pivoted about an axis perpendicular to the table top and about an axis parallel to the narrow edge of the table top. With this spar arrangement, the spars can be easily adapted to the required leg position without the use of additional parts. Extension slides can be moved and locked on the spars. Foot holders of conventional design can be attached to these extension slides without using extensions.

Die Holmanordnundg kann einen balkenartig ausgebildeten Zentralausschub aufweisen, an den über zwei Gelenke mit senkrechten Achsen zwei Zwischenholme angeschlossen sind, wobei an jeden der Zwischenholme über ein Gelenk mit waagerechter Achse ein Endholm angeschlossen ist. Besonders vorteilhaft ist es, wenn der Zentralausschub in einem unterhalb der Tischplatte angeordneten Auf­nahmekanal, der parallel zur Tischplatte und in deren Längsrichtung verläuft, verschiebbar und arretierbar ist. Auf diese Weise lässt sich die Position der Holm­anordnung einfach an die Körpermasse des Patienten an­passen.The Holmanordnundg can have a beam-like central extension, to which two intermediate bars are connected via two joints with vertical axes, an end bar being connected to each of the intermediate bars via a joint with a horizontal axis. It is particularly advantageous if the central extension can be moved and locked in a receiving channel arranged below the table top, which runs parallel to the table top and in its longitudinal direction. In this way, the position of the spar arrangement can be easily adapted to the patient's body mass.

Ein weiterer Vorteil des Operationstisches gemäss der Erfindung besteht in einer die Tischplatte durchdrin­genden Aufnahmeöffnung mit dem Querschnitt eines regel­mässigen Vieleckes für den einen entsprechenden Quer­schnitt aufweisenden Fuss eines Schritthalters, wobei Fuss und Kopf des Schritthalters exzentrisch miteinan­der verbunden sind. Hierdurch lässt sich der Schritt­ halterkopf in mehrere verschiedene Positionen bringen, was wiederum zur Anpassung an die Körpermasse des Pa­tienten von Nutzen ist und eine Arretierung des Schritt­halters im Tisch ist nicht mehr erforderlich. Ein Ausführungsbeispiel eines Operationstisches gemäß der Erfindung ist im folgenden anband der Zeichnung beschrieben. Darin zeigtAnother advantage of the operating table according to the invention consists in a receiving opening penetrating the table top with the cross section of a regular polygon for the foot of a crotch holder having a corresponding cross section, the foot and head of the crotch holder being connected eccentrically to one another. This allows the step Move the holder head into several different positions, which in turn is useful for adapting to the patient's body mass and it is no longer necessary to lock the step holder in the table. An embodiment of an operating table according to the invention is described below with reference to the drawing. It shows

Der in Figur 1 in Seitenansicht dargestellte Operations­tisch weist ein Fahrgestell auf, das in seiner Gesamtheit mit 1 bezeichnet und unten näher beschrieben ist. Auf dem Fahrgestell 1 ist eine teleskopartig längenverän­derliche Säule befestigt, deren unterer Teil mit 2 und deren oberer Teil mit 3 bezeichnet ist. Mit dem oberen Teil 3 der Säule ist eine in ihrer Gesamtheit mit 4 bezeichnete Lagerfläche verbunden, die ihrerseits eine Tischplatte 5 trägt. Die Lagerfläche 4 ist nicht vollflächig, sonder beispielsweise rahmenartig ausge­bildet und die Tischplatte 5 besteht aus einem strah­lendurchlässigen Material, beispielsweise aus Holz. Die Säule 2, 3 kann zum Anheben bzw. Absenken der La­gerfläche 4 und der Tischplatte 5 in Richtung ihrer senkrechten, in Figur 1 mit z bezeichneten Längsach­se verlängert bzw. verkürzt werden, wozu ein in der Zeichnung nicht dargestelltes,in der Säule 2, 3 befind­liches selbsthemmendes Getriebe dient, das über eine Gelenkwelle 6 durch eine in der Zeichnung nicht dargestell­te Handkurbel angetrieben wird, die in einen Kurbelka­sten 7 einsteckbar ist. Im Kurbelkasten 7 befindet sich ein mit der Gelenkwelle 6 verbundenes Übersetzungsgetrie­be, so daß die Handkurbel wahlweise unmittelbar auf die Gelenkwelle 6 aufgesteckt werden kann oder auf die Antriebsachse des Getriebes, so daß der Tisch wahl­weise mit kleinerer oder größerer Geschwindigkeit geho­ben bzw. gesenkt werden kannThe operating table shown in side view in FIG. 1 has a chassis which is designated in its entirety by 1 and is described in more detail below. On the chassis 1, a telescopically variable column is attached, the lower part with 2 and the upper part with 3. With the upper part 3 of the column is connected in its entirety with 4 designated storage area, which in turn carries a table top 5. The bearing surface 4 is not full-surface, but rather, for example, frame-like, and the table top 5 consists of a radiation-permeable material, for example of wood. The column 2, 3 can be extended or shortened in order to raise or lower the bearing surface 4 and the table top 5 in the direction of their vertical longitudinal axis, designated z in FIG. 1, for which purpose a column 2, 3 not shown in the drawing Located self-locking gear is used, which is driven via a propeller shaft 6 by a hand crank, not shown in the drawing, which can be inserted into a crankcase 7. In the crankcase 7 there is a transmission gear connected to the propeller shaft 6, so that the hand crank can either be plugged directly onto the propeller shaft 6 or onto the drive axis of the gearbox, so that the table can be raised or lowered at a lower or higher speed

Zwischen dem oberen Teil 3 der Säule und der Lagerfläche 4 ist ein Gelenk ageordnet, dessen Achse x horizontal und parallel zur Tischplatte 5 verläuft. Durch betätigen des Antriebes dieses Gelenkes, der in seinen Einzelheiten in der Zeichnung nicht dargestellt ist, wird der Tisch um seine Längsachse gekippt. Die Kippbewegung ist nach beiden Seiten, jedoch nur um begrenzte Winkelbeträge, möglich. Die Antriebswelle ist von beiden Schmalseiten des Tisches zugänglich, so dass die zum Antrieb dienende Handkurbel wah-lweise an der einen oder anderen Tischseite aufge­steckt werden kann. Das zweckmässigerweise als Schnecken­getriebe ausgebildete Getriebe ist entweder selbsthemmend oder mit einer Arretierung versehen, damit unbeabsichtigte Kippbewegungen vermieden werden.A joint is arranged between the upper part 3 of the column and the bearing surface 4, the axis x of which runs horizontally and parallel to the table top 5. By actuating the drive of this joint, which is not shown in detail in the drawing, the table is tilted about its longitudinal axis. The tilting movement is possible on both sides, but only by limited angular amounts. The drive shaft is accessible from both narrow sides of the table, so that the hand crank used for the drive can optionally be attached to one or the other side of the table. The gear, which is expediently designed as a worm gear, is either self-locking or provided with a lock to prevent unintentional tipping movements.

In der Achse x des zur Kippbewegung dienenden Gelenkes oder zwischen dieser Achse und der Tischplatte 5 befindet sich ein Drehgelenk mit dessen Hilfe die Tischplatte 5 um eine senkrecht zu ihr verlaufende Achse, die in Fig. 1 mit z bezeichnet ist, verdreht werden kann. Die Drehbewegung kann in beiden Richtungen erfolgen, jedoch nur um begrenzte Win­kelbeträge. Der Antrieb des Drehgelenkes ist in ähnlicher Weise ausgebildet wie der des Kippgelenkes.In the axis x of the joint serving for the tilting movement or between this axis and the table top 5 there is a swivel joint by means of which the table top 5 can be rotated about an axis running perpendicular to it, which is designated z in FIG. 1. The rotary movement can take place in both directions, but only by limited angular amounts. The drive of the swivel joint is designed in a similar manner to that of the tilt joint.

Wie in Figur 2 zu erkennen ist, weist das in seiner Gesamtheit mit 1 bezeichnete Fahrgestell zwei parallel zueinander verlaufende Holme 8 und zwei in einem Winkel zueinander verlaufende Holme 9 auf. In den Holmen 9, die zum Fußende des Tisches weisen, sind feste Rollen 10 angeornet, während sich an den zum Kopfende des Tisches weisenden Holmen 8 Lenkrollen 11 befinden. An den Lenk­rollen 11 befinden sich Bremsvorrichtungen und Feststell­vorrichtungen, durch deren Betätigung jede unbeabsich­tigte Bewegung des Fahrgestells 1 verhindert werden kann.As can be seen in FIG. 2, the chassis designated in its entirety by 1 has two bars 8 running parallel to one another and two bars 9 running at an angle to one another. Fixed rollers 10 are arranged in the bars 9, which point to the foot end of the table, while there are 8 castors 11 on the bars pointing to the head end of the table. On the castors 11 there are braking devices and locking devices, the actuation of which can prevent any unintentional movement of the chassis 1.

Wie insbesondere in Figur 2 zu erkennen ist, befinden sich an der Lagerfläche 4 Geräteträgerschienen 12, 13 und 14, die zur Befestigung von Stützen und anderen Ge­räten, je nach dem wie und wo diese gebraucht werden, dienen. In Figur 1 ist in einer Geräteträgerschiene 12 eine Seitenstütze 15 eingesteckt, die den Patienten abstützt, wenn der Tisch um seine Längsachse x geneigt ist.As can be seen in particular in FIG. 2, there are 4 device carrier rails 12, 13 and 14 on the bearing surface, which serve for fastening supports and other devices, depending on how and where they are used. In FIG. 1, a side support 15 is inserted into a device support rail 12, which supports the patient when the table is inclined about its longitudinal axis x.

Mit 16 ist in Figur 2 eine ausfahrbare Armstrecke be­zeichnet, die besser in Figur 3 erkennbar ist, einer Aufsicht auf die Lagerfläche 4 unter Fortlassung der Tischplatte 5. Die Armstrecke 16 ist an einem aus Stäben 17 und Traversen 18 bestehenden rechteckigen Gerüst befestigt, un zwar je nach Bedarf an der einen oder anderen der Traversen 18. Die Armstrecke 16 ist un die Längsachse er Traverse 18 verschwenkbar und kann in jeder Wïnkelstellung durch Knebelverschlüsse 19 festgestellt werden. Die Stäbe 17 sind gemeinsam durch einen in der Zeichnung nicht dargestellten, im Unterbau 4 befindlichen Antrieb in Längsrichtung ver­schiebhar. Der Antrieb weist ein selbsthemmendes Ge­triebe auf, dessen Atriebswelle im Kurbelkasten 7 endet16 in FIG. 2 denotes an extendable arm section, which can be better seen in FIG. 3, a view of the bearing surface 4 while leaving the table top 5. The arm section 16 is fastened to a rectangular frame consisting of rods 17 and cross members 18, namely depending on the need for one or the other of the crossbeams 18. The arm section 16 can be pivoted un the longitudinal axis of the crossbeam 18 and can be locked in any angular position by toggle locks 19. The rods 17 are displaceable together in the longitudinal direction by a drive (not shown in the drawing) located in the substructure 4. The drive has a self-locking transmission, the drive shaft of which ends in the crankcase 7

In den figuren 1 bis 3 ist eine in der Lagerfläche 4 angeordnete, die Tischplatte 5 durchdringende Aufnahme­öffnung 20 für dei in den Figuren 6 und 7 dargestell­ten Schritthalter 21 angeordnet. Die Aufnahmeöffnung 20 besitzt einen quadratischen Querschnitt, der dem quadratischen Schritthalterfuß 22 entspricht. Mit dem Schritthalterfuß 22 ist über eine Platte 23 ein Schritt­halterkopf 24 verbunden und zwar derart, daß er exzen­trisch zum Schritthalterfuß 22 angeordnet ist. Durch entsprechendes Einstecken des quadratischen Schritthal­terfußes 22 in die Aufnahmeöffnung 20 lassen sich vier verschiedene Positionen des Schritthalterkopfes 24 in Bezug auf die Tischplatte 5 erzielen.In FIGS. 1 to 3, a receiving opening 20 for the step holder 21 shown in FIGS. 6 and 7 is arranged in the bearing surface 4 and penetrates the table top 5. The receiving opening 20 has a square cross section which corresponds to the square step foot 22. A step holder head 24 is connected to the step holder foot 22 via a plate 23 and in such a way that it is arranged eccentrically to the step holder foot 22. By appropriately inserting the square step foot 22 into the receiving opening 20, four different positions of the step head 24 with respect to the table top 5 can be achieved.

Wie ebenfalls in den Figuren 1 bis 3 erkennbar ist, be­findet sich in der Lagerfläche 4 unterhalb der Tischplat­te 5 ein waagerecht und in Längsrichtung des Tisches ver­laufender Aufnahmekanal 25. Der Aufnahmekanal 25 besitzt einen quadratischen Querschnitt und dient zur Aufnahme eines Zentralausschubes 26, einens balkenförmigen Kör­pers mit ehenfalls quadratischem Querschnitt. Der Zentral­ausschub 26 ist im Aufnahmekanal 25 längsverschieblich und kann in ihm durch einen Knebel 27 in der jeweils ge­wünschten Stellung arretiert werden.As can also be seen in FIGS. 1 to 3, there is a receiving channel 25 which runs horizontally and in the longitudinal direction of the table in the bearing surface 4 below the table top 5. The receiving channel 25 has a square cross section and serves to receive a central extension 26, a beam-shaped body with a square cross-section. The central extension 26 is longitudinally displaceable in the receiving channel 25 and can be locked in it by a knob 27 in the desired position.

Der Zentralausschub 26 ist Teil einer Holmanordnung. Diese Holmanordnung, die in der regel zur Aufnahme der Beine des Patienten dient, ist in Figur 4 in Aufsicht und in Figur 5 in Seitenansicht dargestellt. An dem aus der Lagerfläche 4 herausragenden Ende des Zentral­ausschubes 26 sind, symmetrisch zur Längsachse des Zentral­ausschubes, zwei Gelenke 28 angeordnet. Die Gelenke 28 weisen vertikal verlaufende Achsen auf und dienen zur Verbindung von zwei Zwischenholmen 29 mit dem Zentralaus­schub 26 . Die Zwischenholme 29 können mittels der Ge­lenke 28 unabhängig voneinander in einer waagerechten Ebene gegen die Längsachse des Zentralausschubes 26 ver­schwenkt und jeder Stellung durch Knebelverschlüsse 30 arretiert werden. An die Zwischenholme 29 sind über Gelenke 31 Endholme 32 angeschlossen. Die Achsen der Gelenke 31 verlaufen horizontal, so daß die Endholme 33 in vertikalen Ebenen gegen die Zwischenholme 29 nach oben und unten verschwenkt werden können, wobei sie in der jeweils gewünschten Position durch Knebelver­schlüsse 33 arretiert werden können.The central extension 26 is part of a spar arrangement. This spar arrangement, which generally serves to hold the patient's legs, is shown in a top view in FIG. 4 and in a side view in FIG. At the end of the central extension 26 protruding from the bearing surface 4, two joints 28 are arranged symmetrically to the longitudinal axis of the central extension. The joints 28 have vertical axes and serve to connect two intermediate spars 29 to the central extension 26. The intermediate bars 29 can be pivoted independently of one another in a horizontal plane against the longitudinal axis of the central extension 26 by means of the joints 28 and can be locked in any position by toggle locks 30. End bars 32 are connected to the intermediate bars 29 via joints 31. The axes of the joints 31 run horizontally, so that the end bars 33 can be pivoted up and down in vertical planes against the intermediate bars 29, whereby they can be locked in the desired position by toggle fasteners 33.

Auf den Endholmen 32 sind Extensionsschlitten 14 verschieb­bar. Die Endholme 32 sind als Zahnstangen ausgebildet und in den Extensionsschlitten 34 sind Zahntriebe ange­ordnet, die von Hand betätidgt werden, um die Extensions­sclitten 34 auf den Endholmen 32 in die gewünschte Stellung zu verschieben. Die Zahntriebe der Extensions­schlitten 34 sind mit entsperrbaren Rücklaufsperren ver­sehen, die eine unbeabsichtigte Bewegung der Extensions­schlitten auf den Endholmen, die wegen des hohen Eigen­gewichtes der Extensionsschlitten sonst möglich wäre, verhindern. Außerdem sind die Extensionsschlitten 34 mit Arretiervorrichtungen versehen, die dazu dienen, die Positionen der Extensionsschlitten 34 auf den End­holmen 32 wie gewünscht zu fixieren. Schließlich sind an den Extensionsschlitten 34 seitlich verlagert, auf­steigend verlaufende Trägerstützen 35 befestigt, an denen Fussplatten oder andere Vorrichtungen zur Be­festigung der Füsse des Patienten angebracht werden kön­nen, wobei die Verbindung dieser in der Zeichnung nicht dargestellten Teile mit den Trägerstützen 35 zweckmässig über arretierbare Kugelgelenke erfolgt. Die Extensions­schlitten 34 sind auf jedem der Endholme 32 verwendbar, so dass ihre verlagerten Trägestützen 35 wahlweise zwischen den Endholmen oder ausserhalb der Endholme angeorddnet sein können.Extension slides 14 can be moved on the end bars 32. The end rails 32 are designed as toothed racks and in the extension slides 34 there are toothed drives which are actuated by hand in order to move the extension slides 34 on the end rails 32 into the desired position. The pinions of the extension slides 34 are provided with unlockable backstops, which prevent an unintentional movement of the extension slides on the end rails, which would otherwise be possible due to the high weight of the extension slides. In addition, the extension slides 34 are provided with locking devices which serve to fix the positions of the extension slides 34 on the end rails 32 as desired. Finally, laterally displaced, ascending support brackets 35 are attached to the extension slides 34, on which foot plates or other devices for attaching the patient's feet can be attached, the connection of these parts, not shown in the drawing, to the support brackets 35 being expediently carried out via lockable ball joints . The extension slide 34 can be used on each of the end rails 32, so that their displaced support supports 35 can be arranged either between the end rails or outside the end rails.

Die Entsperrbarkeit der Zahntriebe bzw. Rücklaufsperren in den Extensionsschlitten 34 macht es möglich, diese Schlitten zunächst von Hand in die gewünschte Position auf den Endholmen 32 zu bringen und anschliessend mit Hilfe der beispielsweise durch Handräder betätigbaren Zahntriebe in der Weise zu bewegen, wie es zum Einrichten eines Bruches erforderlich ist. Die Gelenke 28 und 31 er­möglichen es, die Zwischenholme 29 und insbesondere die Endholme 32 bei Nichtgebrauch des Tisches in eine platz­sparende Verstauposition zu bringen, wenn nicht beim Ver­stauen die gesamte Holmanordnung vom Tisch entfernt wird dadurch, dass der Zentralausschub 26 aus dem Aufnahmekanal 25 herausgezogen wird. Zur Einstellung der Holmanordnung auf die Körpermasse des Patienten ist lediglich die geeig­nete Positionierung des Zentralausschubes 26 im Aufnahme­kanal 25 erforderlich, nicht etwa Manipulationen an zwei Holmen. Die Schwenkbarkeit der Endholme 32 um die Gelenke 31 und die Verfahrbarkeit der Extensionsschlitten 34 auf den Endholmen 32 ermöglicht die Verbindung der Füsse des Patienten mit dem Extensionsschlitten auf kurzem Wege, so dass die beim Stand der Technik erforderlichen,sich an die Holme anschliessenden vertikal verlaufenden und sich wiederum daran anschliessenden horizontal verlaufen­den Ausschübe fortfallen.The unlockability of the pinions or backstops in the extension slide 34 makes it possible to first bring these slides into the desired position on the end rails 32 by hand and then to actuate them with the help of handwheels, for example To move pinions in the way necessary to set up a break. The joints 28 and 31 make it possible to bring the intermediate bars 29 and in particular the end bars 32 into a space-saving stowage position when the table is not in use, if the entire bar arrangement is not removed from the table when stowing, by pulling the central extension 26 out of the receiving channel 25 . To adjust the spar arrangement to the patient's body mass, only the suitable positioning of the central extension 26 in the receiving channel 25 is required, not manipulations on two spars. The pivotability of the end struts 32 about the joints 31 and the movability of the extension sled 34 on the end struts 32 enables the patient's feet to be connected to the extension sled in a short way, so that the vertically extending and extending the struts that are required in the prior art in turn, subsequent horizontal extensions are eliminated.

Durch die in Fig. 3 dargestellte und in diesem Zusammen­hang beschriebene rahmenartige Ausbildung 17, 18 des Schlittens, an den sich die ebenfalls rahmenartig oder vollflächig aber dann röntgenstrahlendurchlässig ausge­bildete Armstrecke 16 anschliesst, ist auch im Bereich der Ober- und Unterarme der Einsatz von Röntgen-Bildver­stärkern ungehinddert möglich.The frame-like design 17, 18 of the slide shown in FIG. 3 and described in this connection, to which the arm section 16, which is likewise frame-like or fully surface but then radiolucent, is also used in the region of the upper and lower arms to use X-rays. Image intensifiers possible without hindrance.
