Definitions

  • the invention relates to an operating table, in particular for ear, nose and ear microsurgery, in which the operating field remains essentially in the same place during the surgically required pitching and rolling movements of the patient support, and which one in a parallel to the longitudinal direction of the patient support has vertical axis lying roll axis.
  • the support frame which supports the patient support is carried by the parallel axis of the operating table via a parallel lever.
  • a drive guides the rolling movements of the patient support around its longitudinal axis of symmetry by means of the parallel lever steering. Due to the parallel steering, the rolling movements of the patient support run in such a way that an operating point lying in the longitudinal plane of symmetry remains unchanged in the same place in the patient's operating field.
  • the parallel lever steering is complicated. It contributes significantly to the manufacturing costs of an operating table, especially since it has to be carried out twice for structural reasons.
  • the relatively large number of moving parts also has the disadvantage of a large number of articulated connections, so that quite a lot of effort is necessary even in the production of a “play-free” articulation.
  • the overall game increases with the operating time and thus the movement precision and stability. One can imagine what this can mean in the field of microsurgery.
  • the invention is based on the object of creating an operating table of the type mentioned at the outset, which has a substantially low table storage effort with respect to the rolling movements of the patient support, such that the operating field is not shifted. According to the invention, this object is achieved by the features specified in the characterizing part of claim 1.
  • the subclaims relate to advantageous developments.
  • the operating table 1 consists essentially of a standing on the floor 2 and lockable chassis 3, a column 4 attached to it and a box support 5 for a support frame 6 with a patient support 7.
  • the patient support can optionally be in one Head, back, pelvis and leg support part can be divided, which are each adjustable in their position to each other.
  • In the standing column 4 there is a device for height adjustment of the operating table.
  • At the upper end of the pedestal there is an inclined axis pin 36, the elongated longitudinal axis of which forms the roll axis 43 and runs through the operating field 45.
  • the patient support can be pivoted about this axle bolt by means of a drive 50 arranged between the stand column and the support frame.
  • FIG. 3 now shows details of the operating table according to the invention.
  • a hydraulic drive 8 for the vertical lifting and lowering movement of the patient support 7.
  • the free end 10 of the piston rod 11 of the drive also referred to here as a lifting drive, is fastened in a telescopic tube 12 which is guided vertically in the column 4.
  • the cylinder 13 of the drive 8 is attached to the chassis 3 of the operating table.
  • the pitch bearing 16 is fastened on the free end 14 of the telescopic tube 12, in which the pitch axis pin 18 directed transversely to the patient support 7 is rotatably fastened.
  • the box beam 5 is carried by the pitch axis pin 18, which is orthogonal to the vertical plane x-x, in which the roll axis 43 lies, and can be pivoted about it.
  • the box girder 5 (FIG. 4) is provided with two bearings 20 and 21, which can be rotated about the two free ends 23 and 24 of the pitch axle pin 18 protruding from the pitch bearing 16.
  • the pitching movements of the box support 5 with the patient support 7 are controlled by a hydraulic drive 25, for example.
  • the drive 25, hereinafter referred to as the pitch drive can be rotated about a pin 26 on the box support 5, while the free end of its piston rod 27 can be rotated about a pin 28 on an offset 30 of the pitch bearing 16.
  • the box support 5 is provided with a roller bearing 35 in which the axle pin 36 of the patient support 7 is fastened.
  • the axis pin 36 lies in the vertical plane x - x parallel to the longitudinal direction of the patient support.
  • a bearing 40 or 41 of the support frame 6 of the patient support 7 is rotatably supported.
  • the axis pin 36 forms such an angle ⁇ with the patient support 7 that its elongated longitudinal axis 43, i.e. the roll axis, after penetrating the patient support at a point 44, through the center 49 of an operating field 45 which is in or on the head 47 of one on the patient support patient 48 outstretched, runs.
  • the rolling movements of the patient support 7 around the axle pin 36 are controlled by a hydraulic drive 50, for example.
  • the cylinder 51 of the drive 50 hereinafter referred to as a roller drive, is articulated to a pin 52 on the box support 5.
  • the free end 53 of the piston rod 54 is articulated to a pin 55 attached to the support frame 6.
  • the drive 50 is actuated, the patient support 7 is rotated about the roll axis 43 by the axle pin 36 depending on the direction of adjustment according to the arrows 56 and 56 '. Since the roll axis 43 runs through the center 49 of the operation field 45 in or on the head 47 of the patient, the head remains unchanged at the same location during the roll movements of the patient support.
  • the patient's surgical site 58 e.g. the inner ear, describes only a small part of an arc with the radius of the relatively small distance between roll axis 43 and inner ear. The surgical microscope directed at the surgical site 58 therefore only needs to be slightly adjusted by the surgeon.
  • the pitch drive 25 and the lifting drive 8 are controlled in a manner known per se with opposite, as it were compensating movements, by the piston rod 27 of one drive and the piston rod 11 of the other drive simultaneously, but with a predetermined speed ratio in order to compensate for the change in height of the operating field 45 caused by the pitch rotation around the pitch axis pin 18.
  • the operating field 45 and the head 47 of the patient would be raised or lowered.
  • the patient support is simultaneously lowered or raised by the lifting drive 8 by an amount compensating for the height difference, so that the operating field and the head remain virtually unchanged at the same location.
  • this compensation remains subject to a residual error, since only one of a rotational movement, which consists of two translational movements in Cartesian decomposition, for example a vertical and a horizontal translation compensating translational movement, here the vertical one.
  • the remaining error includes the omitted translation movement, here the horizontal one, which, however, is much smaller than the compensated vertical one.
