PEDESTAL BASE OPERATING TABLE Filed June 17, 1930 4 Sheets-Sheet 4 Patented Feb. 13, 1934 'UNITED STATES PATENT OFFICE PEDESTAL BASE OPERATING TABLE Sylvania Application June 17, 1930. Serial No. 461,667

13 Claims.

My invention relates to an improvement in a pedestal base operating table and its novelty consists in the adaptation and arrangement of parts as will be more fully hereinafter pointed out.

There are many operating tables on the market and a number of pedestal base operating tables but all of these require the nurse or operator assisting the surgeon to move from one part of the table to the other in order to throw the table top to the different necessary positions required during the operation.

This interferes seriously with the efliciency of the person assisting the surgeon as it takes them away from the head of the patient where it is essential they should be throughout the operation in order to know the exact condition of the patient throughout the operation.

My invention solves this serious and difficult problem which has for many years handicapped the quick and easy changes of position required to be made in the operating table top at diiferent times during the operation.

Furthermore, my device has simplified and speeded up the shifting of the operating table top from one position to another so that the efficiency of the table has been improved in a very substantial manner thereby eliminating all delays between the necessary shifts of the table top which must be made quickly and easily during the different stages of the operation.

In the drawings 17 is a pedestal base having legs 18 on which are mounted casters 19 in the usual well known manner. A supporting piston 20 of usual construction is mounted in the base 17 in the usual well known manner and is operated by foot pedal 21 to raise and lower the same in an oil plunger construction which has been used in this art for a number of years and is the usual construction. On the head of the piston 20 is rigidly secured a yoke 22 through which is mounted near its head a shaft 23 and on the shaft 23 are mounted two frames 24 which pivot thereon by means of bearings 25 of the frames 24. Said frames 24 also have a semi-circular segmental gears 26 which are made integral therewith and which have gear teeth 27.

A bracket member 28 is rigidly secured to yoke 22 and at its outer end a shaft 29 is mounted therethrough so as to rotate freely therein and carries a hand wheel 30 mounted thereon at its outer end and pinned thereto in the usual manner. A cut gear 31 is also mounted on said shaft 29 inside of said wheel 30 and is pimied to said shaft so as to rotate therewith and meshes with a worm gear 32 which is cut on the lower end of a driving shaft 33 which is supported in a box 34 mounted over said shaft 29 thereby enclosing the gear 31 and the gear 32. The upper end of the driving shaft 33 is supported in a box 35 which is rigidly secured to the side of the yoke 22 and a worm gear 36 is cut on the upper end of said driving shaft 33'and meshes with the teeth 2'7 of segmental gear 26.

A pair of pyramidal supporting members 37 are rigidly secured to the upper side of the frame 24 and table top section 38 is pivotally and hingedly mounted near one end of the same on supporting members 37 on pivot rod 39 in the usual well known manner. A second top member 40 containing a kidney bridge (Fig. 2) is pivotally supported on the brackets 41 mounted in the usual Well known manner at the head of rack bar 42 and is pivotally and hingedly mounted at one end of the same on supporting members 37 on pivot rod 39 in the usual well known manner. The opposite end of table top 38 is also supported in the usual well known manner on brackets 43 mounted on the head of rack bar 44 in. the usual well known manner. Table top head member 45 is pivoted at 46 in the well known manner and may be dropped .and raised by the usual hand operation or secured in the desired position. Foot section 47 of the table top is pivoted at one end on the bar 48 in the usual well known manner and is supported by the bracket 49 pivoted at 50 on the arm 51 which is pivotally secured at 52 to pinion 53 which is internally threaded to travel over the worm gear 54 on shaft 55.

In the frame 24 is mounted a shaft 59 on the outer end of which is mounted a wheel handle 60 and which is adapted to move along said shaft and is held against being pulled off the end of the shaft by means of cross pin 61 running through said shaft 59, which also serves as a key to engage in pocket so as to lock the handle 60 and shaft 59 together so that they will turn together in that position. A cut gear 62 is rigidly secured to the inner end of said handle 60 so as to turn therewith. A spring operated nipple member 63 is mounted in said handle member 60 and is adapted to engage groove 64 in said shaft 59 so as to determine the position of the gear 62 as clearly shown in Figure 3, but is readily dislodged therefrom as the shaft 59 is pushed inwardly or pulled outwardly. On the shaft 59 is mounted a spiral gear 67 in such a way that it will rotate with said shaft 59 and said gear meshes with gear 66 mounted on the end of shaft 55 so that the motion of the shaft 59 is transmitted through said gears 67 and 66 to the shaft 55 and the shaft 55 has Worm gear 54 and the other parts as already described. A shaft 68 is also mounted in the frame 24 on the usual bearings 73 through gear casing 69 and apair of gears 70 and 80 which are formed together and rotate together are rigidly mounted inside of the frame 24 on one end of the shaft 68. Another shaft 71 is mounted in the frame 24 on the usual bearings 72 and a cut gear 74 is rigidly secured thereto at the end inside of the frame 24 and the chain sprocket Wheel 75 is also rigidly secured thereon so as to rotate therewith. At the further end of the frame 24 from the handle 60 and operating part described is another shaft 76 mounted in bearings 77 and a sprocket wheel 78 is rigidly secured thereto so as to rotate therewith and a chain 79 travels over the sprocket wheels 78 and 75 so that said sprocket Wheels and the shafts 76 and 71 to which they are respectively rigidly secured rotate therewith.

The meshing of the gear 62 with gear 70 insures the rotation of the shaft 68 in either direction as desired, this is illustrated in Figure 3. Meshing of gear 62 with gears 80 and 74 effects the rotation of both shaft 68 and shaft 71 simultaneously by the turning of handle 60, which is shown in Figure 5. In order to operate the shaft 59 the handle 60 is pulled out so as to engage the key 61 in the pocket 65 whereby the shaft 59 will be turned with the rotation of the handle 60 and spiral gear 57 will rotate the gear 66 whereby the shaft 55 will be turned.

It is to be noted at this point that the shafts 59, 68 and 71 and also 76 extend across the table and engage in a second frame 24 carried on the opposite side of the table in similar bearings and a second spiral gear 67 meshing with a second gear 66 drives a second shaft 55 with the duplicated elements as described herein and a second set of gear boxes 69 and 81 encase a second set of gears 82 and 83 on the shafts 68 and 76 operating a second pair of rack bars 42 and 44 in the usual well known manner and connected at the upper ends with the table top sections 40 and 38 respectively by means of a second pair of supporting brackets 43 and 41 respectively.

Kidney bridge 56 is rigidly supported on side frame members 84 being secured thereto in a fixed manner. The bridge 56 is composed of a cross bar 85 having a worin gear 86 on one half and a second worm gear 87 on the other half. A second cross bar 88 having a worm gear 89 on one half and worm .gear 90 on the other half carries the frame members 91 and the bridge 56 mounted in said frame members 91. Internally threaded pinion 92 is mounted over the worm gear 87 of the bar 85 and a similar pinion 93 is mounted over the Worm gear 86. Link 94 is pivotally connected at 95 to pinion 92 and pivotally connected at 96 to frame 91. A similar link 97 is pivotally connected at 98 to pinion 93 and pivotally connected at 99 to the other frame member 91 whereby the rotation of the shaft 85 in one direction will draw the pinions 92 and 93 outwardly thereon thereby pushing up on the links 94 and 97 and thereby raising the frame members 91 and the kidney bridge top 56 as desired. The opposite 105 rotation of the shaft 85 by means of the crank engaging the key way at 100 will have the opposite result. The shaft 88 also has a key Way 101 adapted to be engaged by a crank to rotate said shaft in either direction whereby pinions 102 and 110 103 mounted on the worm gears 89 and 90 and carrying body bracket members 104 may be moved to the desired positions on the shaft 88, said pinions 102 and 103 being held against rotation by the contact of cross bar 165 secured to the 115 frame members 91 and which rests against the upper side of the same.

In order to obtain the twelve different principal operating positions commonly used, the following operations of the table are necessary.

The straight general operating position is shown in Figure 1 and the tilting of the entire table top and frames 24 with their connections as described is controlled by the operation of the large handle 30 operating through the gears as described, on shaft 33, whereby the semi-circular gear 27 is turned to the desired position carrying with it the frames 24 and the top mounted thereon on pyramidal brackets 37 supported on the frames 24 and the operation of the hand wheel 60 and 13g gear 62 through the various gears, chains, shafts, pinons and rack bars, as already described operates the different sections 38, 40, 47 and 45 of the table top.

In order to secure the reilex abdominal operating position as shown in Figure 8, it is necessary to mesh the gears 62 with 88 and 74 and then turn the hand wheel 60 to the right whereby the shaft 68 and 71 will be rotated to the desired position together with shaft 76 through chain 79 over brackets 75 and 78 and through the turning of gears 82 and 83 the operation of the two sets of rack bars 42 and 44 will be operated.

In order to obtain the Trendelenburg position as shown in Figure 9, it is first necessary to operate the large hand wheel 30 to turn the entire table top to the desired position, then mesh the gears as shown in Figure 4 and turn the handle 60 to the right.

In order to obtain the reflex thigh position as shown in Figure 16, it is necessary to turn the entire table top to the Trendelenburg position and then by meshing the gears as shown in Figure 3 and turning the hand Wheel to the right as far as possible, then unrneshing the gears as shown in Figure 4 and engaging the key 61 in the hand Wheel 6U, turn the hand Wheel 60 to the right thereby rotating the shaft 59 and the connecting gears and shafts as described.

rEhe Mayo kidney position as shown in Figure 10 is obtained by meshing the ge-ars as shown in Figure 5 and then turning the hand Wheel 60 to the left.

The reverse Trendelenburg position, as shown in Figure 6 is obtained by turning the large hand Wheel 30 to the left to tilt the entire table top, then attach the Hartley foot rest in the usual Well known position for use.

The goitre position as shown in Figure 7 is obtained by first placing the table top in the Trendelenburg position as already described and then turning the head rest 45 in the manner as already described to the desired position.

The pelvic and plastic position as shown in Figure 11 is obtained by returning the table top to the horizontal position as shown in Figure 1 and then unmeshing, the gears as shown in Figure 4 and turning the hand wheel 60 to the right.

The cystoscopic position as shown in Figure 12 is secured by meshing the gears as shown in Figure 5 and turning the hand Wheel 60 to the right, then meshing the gears as shown in Figure 4 and turn the hand Wheel to the right.

The chair position as shown in Figure 13 is obtained by starting with the table in the horizontal position as shown in Figure 1, then meshing the gears as shown in Figure 3 and turn the hand Wheel 60 to the right, and then meshing the gears as shown in Figure 4 and turn the hand wheel 60 to the right.

The extreme lordosis position as shown in Figure 14 is obtained by rst turning the table top to the Trendelenburg position as already described and the meshing the gears as shown in Figure 5 and turning the hand Wheel 60 to the right, then meshing the gears as Shown in Figure 4 and turn the hand Wheel 60 to the right.

The resuscitation position as shown in Figure 15 is obtained by rst placing the table top in the horizontal position as shown in Figure l and then meshing the gears as shown in Figure 3 and turning the hand wheel 60 to the left.
