Definitions

  • Some heretofore known operating tables have a transmission chassis with handwheel and cranks which are operable from the head end of the table and which extend to the head end of the supporting surface of the table.
  • This chassis which has proved very advantageous for the stability of the table and for the mounting of the transmission and the drive therefor interferes, however, with the X-ray operation so as to make the same practically impossible in the area of said chassis.
  • the actuation is, in connection with all operations on the head and neck (for instance in neurosurgery, in the neck, nose and ear surgery, and with the rather frequent struma operation, etc.), not impossible but rather difficult and always there exists the danger of asepsis.
  • FIG. 1 diagrammatically illustrates a view of a conventional movable operating table comprising the features of the present invention.
  • FIG. 2 is a top view of FIG. 1.
  • FIG. 3 diagrammatically illustrates a view of a stationary motor-driven operating table according to the invention.
  • FIG. 4 is a top view ofFlG. 3.
  • FIG. 5 is a section along the line b-b of FIG. 11 and shows and shows the driving mechanism for a manually operable operation table.
  • FIG. 6 is a section along the line c-c of FIG. II and shows a portion of the drive for inclining the table about the axis B-B.
  • FIG. 7 is a section along the line d-d of FIG. 5 and shows the coupling mechanism of the central drive.
  • FIG. 8 is a view in the direction of the arrow e in FIG. 5 and shows the operating knob on the tilting arm.
  • FIG. 9 represents a section taken along the line f-f of FIG. 11 and shows a portion of a drive for pivoting the table abou the axis C-C.
  • FIG. 10 is a section along the line g g of FIG. 11 and shows the transmitting means for adjusting the portions making u the patient-supporting part of the operating table.
  • FIG. 11 is a section along the line a-a of FIG. 5 and shows the drive mechanism of a manually operable operating table.
  • the operating table according to the present invention which comprises a movable or stationary foot section and an upper portion adjustable as to height, is characterized primarily in that the actuating elements for at least some adjusting devices are arranged on a pivotable arm pertaining to the upper portion, the pivot axis of said pivotable arm being approximately vertical when the patient-supporting surface of the table occupies its horizontal basic position.
  • the operating table shown therein comprises a supporting or foot section 1 and an upper portion 2.
  • an arm 3 which is tiltable about a shaft A.
  • the range over which the arm 3 can be pivoted is indicated by the arc B and B and the respective end positions are indicated in FIG. 2 by dot-dash lines.
  • the upper portion 2 of the operating table isadapted to be adjusted as to height by means of corresponding adjusting devices known per se which are usually located within the foot or supporting section 1 and which may be of any standard hydraulic or pneumatic type.
  • the upper portion 2 of the operating table comprises a central portion 11 which at the same time may serve as transmission chassis and which carries or forms the seat plate. Furthermore, the upper portion of the operating table comprises the backplate l2 and the leg plate 13.
  • the central portion 11 is, in a manner known per se and therefore not illustrated, together with the plates 12 and 13 which are linked thereto adapted to be inclined about a horizontal longitudinal axis of the operating table and about a horizontal transverse axis of the operating table.
  • the plates 12 and 13 may be adjusted relative to the central portion 11 and relative to each other. If the operating table has further subdivisions, also such subdivisions may be adjustable relative to each other.
  • the actuating means are mounted on the pivotable arm 3.
  • These adjusting means comprise a handcrank 31 and a selector lever 32.
  • the selector lever 32 By means of the selector lever 32, through the intervention of suitable control shafts and linkage means, the intended transmission for the desired adjustment is controlled whereupon, by means of the central handcrank 31, the adjustment of the operating table is effected.
  • a lurality of handcranks or handwheels may be provided which through individual drive shafts, if desired throughhollow shafts, actuate the various adjusting transmissions.
  • a plurality of handwheels may be combined with corresponding control means and also the number of the adjusting transmissions may be selected in conformity with the particular purpose for which the table is intended.
  • the control transmissions may also include means for adjusting the height of the operatingtable. Instead of providing a handcrank 31, also a motor drive may be selected.
  • the pivotal arm 3 is so connected to the transmission chassis II that it follows the adjustment of said chassis, it may occur that the actuating elements 31, 32, for instance with great inclinations toward the foot or head end, can be actuated only under difficulties which is always the case when the arm is not pivotable. In such an instance, a lateral pivoting will suffice in order to bring about or restore a favorable operating position. Similarly, when the lowering or downward tilting of the backplate 12 is impeded by arm 3, it is possible to move the arm out ofthe way.
  • FIGS. 3 and 4 illustrate an operating table according to which by a unilateral protrusion of the patient-supporting surface a highly satisfactory possibility is realized for X-raying the thorax and pelvis area.
  • the patient-supporting parts are in this instance supported by a column head 21 in which a crosshead 22 isjournaled for pivoting about the shaft or axis B.
  • the crosshead 22 supports the jaws 23 and 23' for pivoting about the axis or shaft C.
  • the jaws 23 and 23' in their turn form the supports for the central portion (seat plate) 24 of the operating table.
  • Pivotally connected to said central portion 24 are the lower backplate 25 and the upper backplate 26 pivotally connected to the backplate 25.
  • each of the arms 3,3 is pivotable by 180 through the arc B, B which is of importance when, for instance during operations on the rectum or during gynecological operations, the backplates 25, 26 are exchanged for the leg plates 27, 27' and 28, 28
  • the free end of the arms 3, 3 are not equipped with a manually operable crank but have pushbuttons 33 for the turning on and turning off of the motor. Also in this instance the arms 3, 3 are provided with the transmission selector 32 for preselecting the desired adjustment. If each adjusting transmission has its own drive motor, the selector 32 is not required and may be replaced by pushbuttons or other electric switches, or the selector may be designed for electrically controlling the adjusting transmission.
  • FIGS. 5-11 illustrate by way of example, a manually operable operating table adapted to be operated by a centrally located crank 31.
  • the arrangement also comprises a tiltable arm located on the longitudinal axis of the table and moving only with the adjustment as to the height and the transverse inclination of the table about the axis 8-8.
  • the table upper portion 2 is by means of screws 10] connected to the foot portion 1.
  • the said table upper portion 2 comprises a column head 21 having a crosshead 22 pivotally journaled for pivoting about the axis B-B.
  • Mounted in the crosshead 22 on the right and left side are jaws 23 and 23 which carry the central portion 24 (FIG. 3) of the operating table for supporting the patient.
  • the head 301 of the tiltable driving arm 3 Pivotally mounted in the crosshead 22 is the head 301 of the tiltable driving arm 3, said head 301 being held in axial direction by means of a ring 302 which engages a groove of the head 301.
  • the ring 302 is connected to the crosshead 22 by means of screws 303.
  • the hollow driving shaft 305 In the operating head 304 of the arm 3 there are journaled the hollow driving shaft 305 and the hollow coupling shaft 306. Connected to the shaft 305 is the manually operable crank 31, while the control member 32 is frictionally connected to the shaft 306.
  • the hollow shafts 305 and 306 are telescopically connected to the shafts 308 and 310 for reducing the length of the arm 3.
  • This connection is a power connection.
  • the shaft 308 and 310 are journaled in the head 301.
  • a bevel gear 312 which meshes with the bevel gear 313 in the head 301.
  • a fork-shaped coupling lever 314 which by means of pins 315 engages the grooves of a coupling sleeve 316 which, in its turn, is connected to the end ofa bolt 317.
  • said bolt 317 there are pull-wedge members 318, 319, and 320, resiliently journaled on pivots 321, 322, and 323 in such a way that their engaging portion is, by means of the thrust of springs, pressed outwardly.
  • Bevel gear 313 is adapted to drive a hollow shaft 324 which is provided with slots to permit passage and movement of the pull-wedge members. Connected to hollow shaft 324 for rotation therewith are helical gears 325 and 326 and the bevel gear 327.
  • the crank handle 31 is rotated, depending on the member 32, by means of which the coupling lever 314 is tilted and the bolt 317 is axially displaced, the respective wedge members 318, 319, and 320 engage the transmission wheels 325, 326, 327 pertaining thereto which then are rotated by the hollow shaft 324 through the intervention of the bevel gear transmission 312,313.
  • control member 32 occupies its central position so that the wedge member 319 engages the groove of the helical wheel 326.
  • the gear 326 meshes with the gear 328 which is mounted on shaft 329 journaled in the jaw 23.
  • the helical wheel 330 which, in its turn, meshes with the helical wheel 331 and is connected to the shaft 332.
  • This worm 336 meshes with the worm wheel 337 which is arranged on shaft 338 in column head 21 for power transfer.
  • the spur gear 339 meshing with the spur gear 340 which is connected to the end of the worm 341.
  • the worm 341 arranged in the column head 21 meshes with the worm wheel 342 which latter is threadedly connected to the bearing pivot of the crosshead 22 in a centering manner by means of screws 343. In this way, when turning the handcrank 31 the crosshead 22 is tilted about the axis B-B while the driving arm 3 which is connected to the crosshead 22 follows this tilting movement.
  • the arrangement of the pivot shafts A, A is in addition to the desired pivoting range, also determined by the structural possibilities. As a rule, the arrangement in a table portion which follows entirely or partially the adjustments, greatly facilitates the structural solution.
  • the arm may be composed of telescopic sections to permit a corresponding shortening of the arm and also a corresponding extension of the arm for special purposes.
  • An operating table structure which includes: supporting means, an upper portion forming the patient receiving and supporting table supported by and vertically adjustable relative to said supporting means, said table including a plurality of sections adjustable relative to each other, adjusting means operatively connected to at least one of said sections for selectively adjusting the same, arm means pivotally connected to said upper portion and pivotable about a vertical axis when the top surface of said patient-supporting table is located in an approximately horizontal plane, and mechanical table-actuating control means including a handcrank and a selector lever respectively mechanically operatively connected to said adjusting means and supported by said arm means.
  • said arm means comprises two arms respectively pivotally supported by said operating table structure with the pivot axes thereof respectively located to the right and left on opposite sides of and substantially symmetrically to the longitudinal central plane of said patient supporting table.
  • pivotable arm means are composed ofsections individually telescopically interengaging each other for selectively shortening and extending said arm means.
