Definitions

  • the invention relates to an operating table according to the preamble of claim 1.
  • a vertical groin support is attached to the operating table frame at the transition point from the end section to the section adjoining it towards the head end, on which the front, the patient's upper iliac crest is supported.
  • a separate spar which is articulated on the lower part and carries an extension device at its free end, is used together with the last support.
  • the support plate is designed to be radiopaque, and the frame of the operating table is designed so that it does not hinder the use of suitable X-ray apparatus. This is also the reason why the support arm forming part of the frame has only a small width. In spite of this, it can be difficult with femoral neck supports to completely cover the surgical field, especially in the vertical direction, since this is only offset to the side by a small amount in relation to the support arm. On the other hand, in the case of thigh positioning, the additional spar attached together with the groin support lies close to the operating field and therefore complicates the use of the X-ray apparatus.
  • the invention has for its object to develop an operating table of the type mentioned in a structurally uncomplicated manner such that a conversion between the femoral neck position and thigh position is possible in a simple manner and in both cases the operating field for image intensifiers or other X-ray devices is easily accessible.
  • the counter-tension rod inserted into one of the vertical receiving openings is laterally offset outwards with respect to the longitudinal center plane of the mounting plate, so that when the patient rests on the neck of the patient with the back lying on the mounting plate, the operating field, i. H. the area of the femoral neck has moved relatively far outwards, which facilitates its supply and fluoroscopy.
  • the counter-tension bar can in many cases be used as a groin support when the upper arm is lying on the patient's side, or instead of the counter-tension bar, a similarly designed, longer than the counter-tension bar support can be inserted into one of the vertical receiving openings without the lateral attachment of a separate last support and one special spars would be required, since in these cases one of the existing spars can be used to attach the extension device. In this case, retrofitting is avoided, or the retrofitting is limited to exchanging the counter-tensioning rod for a longer groin support inserted in the same place.
  • the operating table shown in Figs. 1 and 2 comprises a frame 10, which is either adjustable in height on a fixed column indicated in Fig. 2 and can be tilted on all sides, or which can at least be taken over by a suitable chassis for transport purposes, which can then be carried out with three Above directed pin engages in openings 14, 15, 16 provided on the underside of the frame 10 and indicated in FIG.
  • a mounting plate 18 is arranged for the upper body of a patient, which consists of two base plates 22, 24, which can be adjusted relative to one another by swivel joints 20, and a cushion pad 26 covering them and at the left end of which in FIGS. 1 and 2 a mounting plate 28 for the Connects the patient's head.
  • the mounting plate 18, which can be X-rayed, includes an end section 30, which is used to support the pelvis of the patient in femoral neck nailing and similar operations in which the patient is supine.
  • a perpendicular counter-pull rod 32 is then provided, which has a rigid axis 34 and, in its sections lying at the height of the bearing plate 18 and above the bearing plate 18, a padding 36 concentrically surrounding the axis 34.
  • the frame 10 is designed as a support arm 42, which extends along the longitudinal central plane 38 of the mounting plate 18 up to the end face 40 of the end section 30, with the counter-pull rod 32 at its free end inserted in a manner to be described and held removable.
  • two horizontal bars 44, 46 are each pivotably articulated about a vertical axis, each of which carries at their free ends remote from the frame 10 an extension device 48 designed as a tension spindle unit.
  • an extension device 48 designed as a tension spindle unit.
  • two triangular, padded support plates 50, 52 are provided as additional devices, which complement the essentially trapezoidal end section 30 in the plan view of FIG. 1 to a rectangular basic shape, the width of which is at least approximately as large as the width of the section 54 of the mounting plate 18 adjoining the end section 30.
  • Two additional leg support plates 56, 58 are shown as additional plates, which in their illustrated use position extend parallel to one another from the end section 30 of the mounting plate 18 and each have a support rod 60 (FIG. 2) have ' near the longitudinal center plane 38 (FIG. 1) of the mounting plate 18 extends parallel to the latter.
  • the support plates 50, 52 as well as the leg support plates 56, 58 have, as can be seen from FIG.
  • the counter-tension rod 32 is in its use in a position offset to the outside relative to the longitudinal center plane 38 (FIG. 1) of the mounting plate 18. This is achieved in that at the frel-n end of the support arm 42 two vertical receiving openings 64 are provided for the pluggable reception of the axis 34 of the counter-pull rod 32, which lie on both sides of the longitudinal central plane 38 of the mounting plate 18 and which are offset to the outside relative to this longitudinal central axis 38 by less than half the greatest width of the mounting plate 18; the counter-tension rod 32 is inserted with its axis 34 into one of these vertical receiving openings 64 and is offset outwards by a corresponding distance with respect to the longitudinal center plane 38.
  • this outward displacement is expediently chosen such that the distance between the center of a vertical receiving opening 64 and the longitudinal center plane 38 is between 5 cm and 15 cm. In the exemplary embodiment, this center distance is 11 cm, while the greatest width of the mounting plate 18 is approximately 50 cm.
  • the counter-pull rod 32 is upwards relative to the longitudinal median plane 38, i. H. offset to the left relative to the longitudinal axis of a patient lying on his back on the support plate 18.
  • the left thigh neck of the patient is thereby moved outward relative to a positioning of the patient oriented along the longitudinal center plane 38 of the support plate 18 and is therefore particularly easily accessible to the operating doctor.
  • the support plate 52 is removed here and therefore does not hinder the operation or its metallic support rod, which will be described with reference to FIG. 6, the fluoroscopy of the operating area.
  • the lateral displacement of the counter-pull rod 32 with respect to the longitudinal center plane 38 has the consequence that the counter-pull rod 32 can serve as a groin support for the patient during operations with a patient lying on the side, for example in the case of thigh medullary nailing.
  • the counter-tension rod 32 shown in FIG. 1 is to be replaced if necessary by a longer, otherwise similarly shaped strip support 66. It is therefore not necessary to mount a separate last support with a separate spar for an extension device in the otherwise usual manner to the side of the mounting plate 18, for example at the transition between the end section 30 and the subsequent section 54.
  • the extension device 48 is provided
  • Spars 44, 46 are expedient, as in the exemplary embodiment, of two sections 68, 70 connected to one another in an articulated manner, the section 68 lying towards the support arm 42 being noticeably shorter and the longer section 70 being telescopically extendable in the usual manner and in the length desired in each case in a manner not shown can be locked.
  • the pivot joint 72 connecting the sections 68, 70 and allowing pivoting about a vertical axis can be locked in the pivot position desired in each case by means of a lever 74.
  • the pivotability of the sections 68, 70 relative to one another is also expedient when the operating table is used for operations on the neck of the femur and similar interventions in which the patient lies on the back, since the bars 44, 46 are thereby particularly easily brought into a position. where they do not hinder the use of an image intensifier or other X-ray apparatus.
  • the vertical receiving openings 64 have a parallel to the longitudinal center plane 38 of the Ingerungsplatte 18 measured center distance from the end face 40 of the end section 30, which approximately corresponds to the radius of the counter-pull rod 32 in its section lying above the mounting plate 18. Furthermore, the end section 30 above the vertical receiving openings 64 has open recesses 80, 82 to its end face 40 and to its longitudinal sides 76, 78, in the exemplary embodiment formed as an inside corner, the cross section of which is slightly larger than the cross section of the counter-pull rod 32 in which the bearing plate 18 penetrates Section is.
  • the end section 30 extends in the longitudinal direction to such an extent that its end face 40 is approximately aligned with the side of the counter-pull rod 32 facing away from the mounting plate 18. Because of this relatively large longitudinal extent of the end section 30, it is possible, when using the counter-pull rod 32 or a groin support 66, to still support the pelvis of the patient lying on the side on the end section 30.
  • the trapezoidal taper of the end section 30, which facilitates access to the operating area, in particular to the femoral neck area, when the support plate 50, 52 is removed during the operation, is made in the exemplary embodiment in such a way that the imaginary intersection points of the long sides 76, 78 of the end section 30 with its end face 40 from the longitudinal center plane 38 of the support plate 18 have a distance that is approximately as large as the center distance of a vertical receiving opening 64 from the longitudinal center plane 58 plus the radius of the counter-pull rod 32 in its section lying above the bearing plate 18. This results in the already mentioned position of the counter-pull rod 32 in a recess 80 or 82 designed as an inside corner, which has 64 advantages with regard to the accessibility of the vertical receiving openings.
  • the vertical receiving openings 64 are formed in an adapter 84, the construction of which can be seen in more detail in FIGS. 3 to 5.
  • the adapter 84 comprises two transverse, namely perpendicular to the longitudinal center plane 38, horizontal, mutually aligned pipe sections 86, 88.
  • the vertical receiving openings 64 are formed as bores which penetrate the respective upper and lower walls, so that one at the lower end of the Axis 34 (FIG. 2) of the counter-pull rod 32 formed pin 90, the length of which is slightly greater than the outer dimensions of the pipe sections 86, 88, can be kept inserted.
  • transversely directed pipe sections 86, 88 also serve as receptacles 92, 94 of square cross section lying below the mounting plate 18 laterally outside the vertical receiving openings 64, transversely to the longitudinal central plane 38 and horizontally, in which an additional device such as the support plate 50 or 52 (Fig 1) can be kept inserted with a suitable horizontal pin.
  • an additional device such as the support plate 50 or 52 (Fig 1) can be kept inserted with a suitable horizontal pin.
  • the mutual outer distance of the transversely directed receiving openings 92, 94 is expediently, as in the exemplary embodiment, only slightly larger than the mutual center distance of the perpendicular receiving openings 64.
  • the height of the transversely directed receiving openings 92, 94 is selected so that it lies between the underside of the mounting plate 18 and the swivel joints 96, 98 of the bars 44, 46 located on the support arm 42; the perpendicular center-to-center distance between the bars 44, 46 and the transverse receiving openings 92, 94 is expediently between 8 cm and 15 cm or more in order to allow the bars 44, 46 to pivot through under auxiliary devices, the horizontal pins of which in the transverse receiving openings 92 , 94 are plugged in.
  • the transverse pipe sections 86, 88 are welded to the outside of a further pipe section 100, 102 at their inner ends lying towards the longitudinal central plane 38. These pipe sections 100, 102 extend on both sides of the longitudinal center plane 38 parallel to this and thus also parallel to one another in the horizontal direction. Their inside and outside cross sections are the same as the inside and outside cross sections of the transverse pipe sections 86, 88.
  • the longitudinal pipe sections 100, 102 with their end faces pointing away from the mounting plate 18 are approximately aligned with the vertical outer sides of the transverse pipe sections 86 pointing away from the mounting plate 18 , 88 and thus approximately with the end face 40 of the end section 30.
  • the longitudinally directed pipe sections 100, 102 open at their mentioned end faces and thus form two longitudinally and horizontally directed receiving openings 104, lying at the same height as the transverse receiving openings 92, 94. 106.
  • the longitudinal receiving openings 104, 106 serve for the pluggable receiving of suitably dimensioned, cross-sectionally square, horizontal pins of additional plates, which in their position of use have an upper side which is at least approximately flush with the upper side of the end section 30 of the bearing plate 18.
  • additional plates are the 1 and 2 leg support plates 56, 58, which in the position of use extend parallel to one another from the end section 30 of the mounting plate 18 and each have a support rod 108 (FIG. 2) which extends horizontally near the longitudinal center plane 38 parallel to the latter and ends in a pin, not shown, which is adapted to a longitudinal receiving opening 104, 106.
  • the above-mentioned pelvic support plate can also be provided as an additional plate, which can serve to extend the end section 30 when the groin support is held laterally in one of the transverse receiving openings 92, 94 and which can have two horizontal pins which can be inserted into the longitudinal receiving openings 104, 106.
  • the longitudinal pipe sections 100, 102 have a suitably dimensioned length for receiving the aforementioned pins and, for this purpose, as can be seen from FIGS. 3 and 5, extend with their ends facing the mounting plate 18 over the vertical side of the transverse pipe sections lying there 86, 88 further.
  • the center distance of the longitudinally oriented receiving openings 104, 106 formed by the longitudinally directed pipe sections 100, 102 is relatively small and should in any case be less than the mutual center distance of the vertical receiving openings 64. In the exemplary embodiment, the mutual center distance of the longitudinally oriented receiving openings 104, 106 is approximately 10 centimeters. Due to this small center distance and the corresponding small distance between the support bars 108 of the Beinauf- i layer of boards 56, 58 is a slight nieuchtbar-; speed of the latter.
  • the mutually facing vertical sides of the longitudinal pipe sections 100, 102 are welded in their regions aligned with the transverse pipe sections 86, 88 to an intermediate part which is formed by a vertical pipe section 110 which is similar in square cross section to the pipe sections 86, 88, 100 and 102 which extends from the height of the common upper sides of the tube sections 86, 88, 100, 102 down to the free end of the support arm 42 and is fastened to it by means of screws 112, 114.
  • the adapter 84 essentially has an upright T-shaped shape.
  • the free end of the support arm 42 is, as can be seen in particular from FIGS. 4 and 5, reverse T-shaped in cross section.
  • it has a central part 116 extending along the longitudinal central plane 38, on the front side of which facing away from the mounting plate 18, the vertical pipe section 110 is fastened by means of the screw 112.
  • the latter passes through both walls of the vertical pipe section 110 and is surrounded in the interior thereof by a sleeve 118 which prevents the vertical pipe section 110 from being compressed.
  • the end of the support arm 42 on both sides of the middle part 116 has two flanges 120, 122 which project outwards in the transverse direction and which lie on the middle part 116 also protrude slightly in the longitudinal direction.
  • the wall of the vertical pipe section 110 lying away from the mounting plate 18 continues downward in a flange 124 which is fastened by means of the screws 114 to the region of the flange extensions 120, 122 projecting beyond the central part 116 in the longitudinal direction.
  • the adapter 84 is overall very rigidly connected to the free end of the support arm 42, which is important in view of the bending moments exerted by the leg support plates 56, 58 on the adapter 84, for example.
  • the upper side of the adapter 84 is also connected to the end section 30 of the mounting plate 18 via support columns 126, 128, whereby the bending stiffness is further increased and the end section 30 is additionally supported in the vertical direction.
  • the upper and lower sides of the transverse pipe sections 86, 88 are each reinforced in the vicinity of the vertical receiving openings 64 by means of welded-on metal rings 130, 132 or 134, 136.
  • the swivel joints 96, 98 by means of which the spars 44, 46 are articulated at the free end of the support arm 42, are arranged on both sides of the center plane 38 of the ling, at a mutual distance, namely on both sides of the central part 116 and vertical pipe section 110 on the upper sides of the flange extensions 120, 122. They can be locked in the desired position using levers 138, 140.
  • the support plate 50 is of a corresponding, mirror-symmetrical design.
  • the support plate 52 has a radiolucent, padded horizontal upper part 142, a horizontal support rod 144 lying below the upper part 42, vertical pins 146, 148 connecting the upper part 142 and the support rod 144 and a horizontal pin 150 of square cross section, which is an extension of the Support rod 144 is formed and in the plan view projects above the upper part 142 to the outside.
  • the pin 150 is inserted into the transversely directed receiving opening 94 of the transversely directed pipe section 88.
  • the pin 90 of the counter-pull rod 32 and thus the bore forming the vertical receiving opening 64 have a smaller diameter than the clear width of the transverse pipe section 88 measured in the horizontal direction, and the pin 150, the length of which is greater than the length of the Pipe section 88 between its mouth end and the vertical receiving opening 64 passing through it has one to it At the end open, vertical, slit-shaped recess 152, the width of which is at least as large as the diameter of the pin 90 and the vertical receiving openings 64. It is thus possible to attach or remove the support plate 52 at any time despite the inserted counter-pull rod 32, and vice versa insert or remove the counter-pull rod 32 or a strip support 66 (FIG. 2) at any time, regardless of whether the support plate 52 is mounted or not.
  • the support plates 50, 52 may be expedient to provide the pin with a vertical bore which is aligned with a vertical receiving opening 64 when the pin is inserted into a transverse receiving opening 92, 94, and to insert a bolt into the latter which defines the vertical receiving opening 64 and penetrates said hole of the pin to lock the latter.
  • This construction is particularly expedient for strip supports which are used in special cases and which are laterally attached instead of a support plate 50, 52.
