vested in the Attorney States General of the United Application September 5, 1942; Serial'No. 457,509

In France June5,1941 l 3 claims. (o1. 25o-55) My invention relates to adjustable tables such as those for surgical purposes, those used as drawing boards, etc. and it refers more particularly to tables for surgeons operating with the aid ol X-rays.

My invention has for its object to provide a table of the kind above-referred to which will be more easily adjustable and thus more convenient in use than the known tables.

It is a further object of the invention to provide a table for surgical and the like purposes for use with an X-ray tube device, in which the table has a single supporting column carrying a substantially flat track on which is movably mounted a body support for cycloidal movement on the track. On the under side of the body support there is movably carried a support for the X-ray tube device, and the mounting of thel body support on the column for cycloidal movement on the track is positioned and dimensioned to preof the main parts when the table is oscillated about its transverse axis.

Figs. 7, 8 and 9 refer to the electrical equipment of the table which is shown in end view, plan view and partial view to an enlarged scale, respectively.

Fig, 10 is a perspective View showing a lateral abutment.

Fig, l1 shows the stretcher, the "arching device and the shafts which may be associated therewith.

Figs. 12 and 13 are respectively a perspective view and a plan View of an X-ray bulb support adapted to be associated with the table.

The table shown in the drawings comprises a base I supported by means of castor wheels, the said base being provided with a telescopic column 2 -associated with a gearing to operate same in order to vary its height.

The table proper 3 is supported by column 2 through a mechanism adapted to permit its'- adanism comprising a pair of horizontal racks 4 and` Ig ilxed to side members 5d and 5g connected by a transverse member 5, and a pair of toothed sectors 6 and 6g cooperating with said racks. Members 5, 5d and 5g form a rigid structure iixed to column 2, while sectors B and 6g are rigidly carried by the longitudinal members 'Id and 'Ig of a frame 1 which carries the table proper 3, as it will be explained below.

Carriages 8 and 8g are adapted to slide longitudinally along the upper part of side members 5d andg and they are actuated by a pair of longitudinal screws 9 and Sg horizontally and pivotally carried by the end portions 5t and 5p of members 5d and 5g. They are provided with trunnions on which sectors 6 and 6g are pivoted.

- Fig. 6 clearly demonstrates the operation of the gearing described.

When screws 9 and 9g are actuated in unison (which is obtained by any appropriate means, such as chains and sprockets) carriages 8 and 8g are moved longitudinally and sectors 6 and 6g are oscillated together with frame 'I to which they are rigidly lixed. The assembly comprising the X-ray bulb and associated parts, carried by frame 7, thus assumes positions such as shown at IGA, IIIB and IIIC and is tangent to a cylindrical geometrical surface XY, the section of which is a eycloid. It will easily be grasped that this is an advantage with respect to the mere pivoting of frame 'I about a lixed transverse axis, as is the known constructions; more particularly my invention provides ample space for the X-ray bulb for any position of the table and avoids any risk of breakage of the same against the supporting column 2.

Y Frame 'I supports two columns I I and Ilp respectively lixed to its rear and front transverse members 'It and 1p, said columns pivotally carrying the rear and front transverse members 3i and 3p of the frame 3 forming the table proper. Two rods I2 and I2p are articulated at their upper ends to one of the ends of members St and 3p while their lower ends are pivotally connected with carriages I3 and I3p forming nuts on transverse screws I4 and Mp respectively. It will be understood that by operating screws Ill and Mp in unison by appropriate means, table 3 may be pivoted at will about a longitudinal axis.

As shown in Figs. 7 to 9, column 2 may be operated by, an electric motor I5 housed within base I, this motor being electrically connected through a plug |50 (Fig. 3) with a pair of pedals |51 and I5Z (Fig. 1) disposed on a separate base or switchboard I6 and corresponding to upward and downward movement of column 2. There is also provided a. switch with an operating head |510 connected by a chain |520 with member and adapted to be actuated when the table reaches respectively its lowerrnost and its uppermost positions to cause stoppage of motor I5 while permitting its rotation in the reverse direction.

The mechanical connection between motor I5 and column 2 comprises a clutch 2 and a shaft with a square and |500 projecting from the gear case and adapted to receive an actuating handle, in order to permit hand actuation when the motor is de-clutched. l

A second electric motor I1 is provided to actuate screws il and 9g; it is energized through a plug |10 to which it is connectedby means of Wires passed through an `articulated tubing I8. Plug |10 is itself connected with pedals I11 and I12 on base I6. And there is also provided a pair of end switches |110 and I 1,20 to cause motor stoppage at the ends of the stroke.

In Fig. 7 it will befseen that motor I1 drives a, shaft ld extending horizontally along one sideof the structure, said shaft being chain connected with another shaft |1g extending along the other side, and shafts Id and |`lg driving screws 9 and Sy by means of chains and sprockets. Hand actuation is enabled by a square end i100 in cooperation with a clutch not illustrated.

A third electric motor IS is disposed within a casing 'i0' on member lt of frame 1;",it is controlled through a plug I90byl pedalsflill and |32 on base ldassociated with end switches IQN and |920; The gearing between motor I9 and screws I4 and lllpcomprises a pair of gears connecting said scre'ws'with an actuating shaft ld carried along member ld. Shaft Illdis connected with motor i9 by means of a slidable pinion I 93 forming a clutch and there is provided a square i900 to vpermit hand actuation.

The support l0 of the X-ray bulb is slidably iik-edV on the transverse sides and 20t of a frame, the longitudinal sides 20d and 28g =of which kare slidable along members vlol and 1g. The side member 20g is provided with two superimposed longitudinal bores; the rst one, which is threaded, is adapted to receive a screw. 2| plvotally supported by frame 1; and the second one -which is cylindrical, slidably receives a square shaft 22 also pivotally carried by frame 1. There provided a chain.l sprocket 22g on shaft E2 and another chain sprocket 22d loose on a :Sournal carried by the other longitudinal.

sideV 25d, and sprockets 222g` and 22d ,are connected with cach other by means of a chain fixed to pin i60 carried by the corresponding transverse side of support IB.

, Itwill be understood that the X-ray bulb ma thus be moved longitudinally by actuating screw 2l. and transversely by actuating shaft' 22.

squareY ends 2.!0 and 220, or electrically, by means of additional frame freely carried by the meansof the kind described with reference'to" Figs. 7 to 9.

yThe arching device comprises a pairpof rec-v pairs of slides 25, which are mounted respectively;

on the right and left transverse members of frame 3 or, preferably as shown, on the transverse-megu-V This actuation may b'e performed by hand, throughVV such means comprising bers 26d and 25g of an additional frame freely carried by the former and adapted to be used as a stretcher for carrying the patient, by means of sockets 2B provided in the angles of the said additional frame to receive gudgeons 21 projecting upwardly from the `carrier shafts 21d and 21g (Fig. l1). Slides 25 are provided with inwardly projecting edges having on their upper face a series of notches adapted to receive the transverse pins of wings 24 respectively.

Means are also provided to move the slides of each pair towards those of the other pair, preferably a pair of screws 28d and 28g pivotally carried by the additional frame 26 in parallel relation with respect to the longitudinal members thereof, such screws being provided with opposed pitches in such a manner that by rotating same the two pairs of slides may be moved in opposed direction. Screws 23d and 28g are driven either by hand, through a square endv 28, or electrically by means such as described with reference to Figs. '1 t0 9.

The table described also comprises a head support 29 and a foot support 29p, each being carried by breaches driven through the tubular ends of the longitudinal members of frame v3 and iixed at the appropriate position by means such as radial pins.

Fig. lo'shows an adjustable abutment comprising a split collar 3D slidably keyed on transverse member 3g (or 3d) and clamped in position by means of a screw 301, a double plain collar 3| formed of two elements between which collar 3|] is positioned, and a body SI1 integral with collar 3|, the said body receiving the lower end of a tubular ,rod 32 forming a telescopic arrangement with another 33. The upper end of rod 32 is split and it is provided with a clamping screw 321. Rod 22 carries asplit collar in whichv thereniay be clamped a rod 3d to which there is articulated the curved plate 35 forming the abutment proper. A screw 331 permits of clamping rod 34 .at the desired position.

Collar 3| is angularly fixed on member 3g'by means of ratchet teeth cut in collar @Gand engaged by a pawl, not illustrated, pressed by a spring and freed by a hand lever iii?. lt will readily be grasped that by lifting lever SI2 the pavvl is disengaged from the ratchet and collar 3Q is free to'rotate.

There is associated with the table described an X-ray support comprising a carriage 35 supported by castor' wheels and provided with broachesl and 31g by means of which it may be xed to the base I of the table through sockets (notshown) provided on the same. rlhis carriage supports two uprights 39d and. 39g connected by a 39. Uprights 39d and'39g slidably support sleeves (lo and dilo, each carrying another sleeve All and Mg respectively, with their axes horizontal. driventhrough sleeves ll and'tllg; they are preferably-square in cross-section, as well as the corresponding sleeves themselves, and they are Pulleys 48d and 48g are varranged at the upper end of uprights 39d and 39g on the same trans'- verse shaft 48. The lower end of said uprights also comprises pulleys 49g and 49 and the said pulleys receive two endless wires or strings 49g and 49d attached to noses 50 and 50g carried by sleeves 40 and 40g. Counterweights 5I and 51g are provided to balance the weight of the parts associated with the sleeves.

The carriage also supports theelectrcal apparatus 52 supplying current to the X-ray bulb, and it is provided with a column 53 with an articulated handle 54 by means of which the carriage may be moved.

It will easily be grasped that the carriage thus established permits of placing the X-ray bulb and the corresponding frame at any position. Fig. 13 shows by way'of example in dash and dot lines the position corresponding to an X-ray eX- posure with the bulb under the body.
