Definitions

  • a support column is fixed to the base and is inclined with respect to the vertical.
  • a movable support is slidable with respect to the inclined support column so that it can be moved up and down with respect to the base.
  • a patient-supporting means such as a table top or seat is carried by the movable support. Means is provided for raising and lowering the movable support.
  • Surgical operation tables normally comprise a padent-supporting platform or table top which is supported on a movable or fixed base in such a way that the height of the table top with respect to the base can be adjusted as desired.
  • the support and height adjustment mechanism is usually relatively complicated and expensive.
  • An object of the present invention is to provide a simple way of supporting the table top.
  • FIG. 1 is an elevation of an operation table
  • FIGS. 2 and 3 are fragmentary views of part of a support means of the table.
  • a surgical operation table comprises a movable base 1 although if desired the base may be fixed.
  • a support column 2 of rectangular cross-section is fixed to the base 1 and is inclined with respect to the vertical. Thus, it has two opposed surfaces disposed in vertical planes and two opposed surfaces disposed in inclined planes.
  • the ram 3 is raised or lowered by hydraulic means (not shown) under the control of a pedal 11. Neither the hydraulic means or the construction of the table top forms any part of the present invention.
  • the top of the ram 3 carries a yoke 5 which itself carries the patient-supporting table top 4.
  • the support column 2 and the ram 3 are both tubes of rectangular cross-section.
  • Each of the two walls of the support column disposed in vertical planes is provided with a set of four low-friction bearing pads 6 which extend into the interior of the column and bear on the ram 3.
  • On each of the other two walls is a pair of pressure pads 7 and a pair of pressure bearing rollers 8.
  • the rollers 8 at the forward or lower wall 9 are arranged above the pressure pads and the rollers at rearward or upper wall 10 are arranged at the bottom as shown in FIGS. 1 and 2.
  • the bearing pads and rollers are adjustable so that the pressure applied by them to the ram can be varied. This adjustment also permits compensation for wear to be made. As is readily apparent from FIG.
  • the load of the movable support column 3 is taken by the rollers 8 and pads 7 of the lower inclined wall 9.
  • the particular arrangement of the roller on the upper part of the lower wall and on the lower part of the upper wall, as shown, serves to prevent any rocking movement between the movable support column 3 and the base support column 2.
  • the invention makes use of the stresses produced by the inclined support-column to assist in maintaining the movable member in any desired position with respect to the fixed inclined column. Owing to the inclination the movable member is permanently loaded in one direction. During use, the rollers and/or bearing pads can be tightened against the movable member to compensate for wear.
  • the movable member could support the seat of an operation chair instead of a table top.
  • a device for supporting a patient during surgical procedures comprising a base member, an upwardly extending support column fixed'to the base and inclined with respect to the vertical, a movable support column reciprocably slidable within and with respect to the inclined support column, a patient-supporting platform mounted atop the movable support means for raising and lowering the movable support and the patient-supporting platform thereon along a plane inclined from the vertical, the support column having two opposite walls in parallel vertical planes and two opposite walls in parallel inclined planes, the movable support reciprocably sliding within the support column, low friction bearings between the fixed support column and the movable support column including a pressurebearing pad and a pressure-bearing roller mounted on each of the opposing inclined walls of the support colunn, the lower of the inclined walls having the load supporting bearing roller disposed above and spaced from the bearing pad and the upper of the inclined walls having the load supporting bearing roller disposed below the bearing pad, thereby to reduce rocking movement of the movable support about the aforesaid load
