GILBERT, OF MUSKEGON, MICHIGAN SURGICAL OPERATING surronr Application filed October 26, 1929. Serial No. 402,569.

This invention relates to a surgical operating'support and more particularly to a folding portable bed or operatlng table esj; pecially useful in connection with obstetrical cases.

7. made as to prevent complete sterilization and also some are so constructed as to be cumbersome when utilized as a portable device.

An object of the present invention is to provide a light, readily portable simple, yet

7 rigid, obstetrical table or support which is 5 comfortable for a patient'and which may be kept clean and sanitary.

A further objectof the invention is to provide a portable obstetrical or surgical bed which may be placed upon the dressings of an ordinary bed with the patient lengthwise of the bed in a normal position, but upon which she can be turned crosswise of the bed for operative measures, and the desired positions secured without moving the equipment on the bed or disturbing the'drainage or dressings. It is often vitally important that this change in position be accomplished quickly and with minimum effort. Heretofore no such equipment has been provided with adequate adjustments for such change.

Another object of the invention is to provide an obstetrical'table with knee rests and standards for supporting the knee rests in any position,- which rests and standards may be readily adjusted and also separated for packing in small compass for ready portability.

Another ObJGCt Of the invention is to provide knee rests for use with obstetrical tables and the like, which rests are hinged or jointed for angular adjustment about the hinges for the purpose of greater comfort to the pa.- tient, and also for the purpose of allowing packing of the same in a more compact com.- pass than possible with the present type of knee rests.

Another object 'of the invention is to provide standards for the knee rests which standards have offset ends whereby greater lateral adjustment of the knee rests is secured inwardly and outwardly of the side margins of the table. i

A further object of the invention is to provide a foldable portable all metal obstetrlcal bed or table having knee rests and standards for supporting the rests, which bed is foldableinto compact form and in which may be stowed the knee rests. and

standards and which also is provided with a i portable electric light, one terminal of which may be connected to a battery within the bed and another terminal of which may be attached to any part ofthe bed,'knee rests, or standards for closing circuit through the light, whereby the same may housed in any position about, aboveor around the structure.

A still further objectof'this'invention is to provide a foldable, portable, obstetrical bed withknee rests and standards forthe support of the rests, all of which may be packed in compact relation within the compass of an ordinary suitcase for ready portability.

The above, other and further objects of the invention will be apparent from the following description, accompanying drawings and appended claims. i

An embodiment of the invention is illustrated in the accompanying drawings and the views thereof are as follows:

Figure 1 is a top plan view of an obstet-' rical bed embodying the present invention and showing the bed in opened position with the knee rests and standards for the same in,

Figure 3 is a bottom plan view of the il- I knee rest standards with the parts in variously adjusted position.

Figure 5 is a perspective view of a case with a port-ion broken away showing parts of the illustrated form of the invention in folded and packed relation.

Figure 6 is an elevational view of one kind of electric light support having a flexible neck.

Figure 7 is a view similar to Figure 6 taken at 90 with respect to Figure 6.

The drawin s will now be explained.

The form bed or support chosen to exemplify the present invention includes two hi ed metal sections A and B which are [h2 8 preferably of cast aluminum, so as to be light, rigid, and readily sterilized. The sections A and B are hinged together by means of hinge pins 1 which extends through ears 2 of the section A and adjacent apertured portions 3 of the section B.

The section A is shown as provided on its underside with a flange 4 extending about three of the margins of the underside of the section or leaf, while the underside of the section B is shown as having a flange 5 extending about the four sides of the same, which flange is thickened at the parts 3 for receiving the pivot pins 1,. The flanges 4 and 5 serve as means for preventing movement of the bed or table when the same is opened on any convenient support, such as on the bedding of an ordinary bed or on a table or other place where the surgical support of the invention may be used.

The undersides of the outer corners 6 and 7 of the leaf A and corners 8 and 9 of the leaf B are thickened and provided with openings 10 through each one of the thickened corners, which openings are substantially circular for a greater portion of the length of the same and which openings have lateral cutouts 11 for a purpose to be later explained.

An electric battery C is removably supported on the lower side of one of the leaves of the bed. The battery C is shown secured to the underside of the leaf B by means of a cli 12, another clip 13 with the latter of whic is associated a flange 14 to receive a sprin 15 between it and one end of the battery The spring 15 serves as aconnection between the battery and the metal leaves of the table. A jack opening 16 is provided ad- 'acent the other end of the battery for receivmg one end 17 of a plug connector attached to the positive terminal conductor 18 of a portable light.

The depth of the flanges 4 and 5 on the undersides of the leaves A and B is such as to receive the battery C and also to contain the knee supports and knee support standards and the light and hand and leg straps used with a table of this sort when the same is folded for portability.

A pair of knee support standards E and F are provided, each of which has a cylindrical end 19 for entering one of the openings 10 through the corners of the leaves and which end 19 is provided with a laterally extending pin 20 for entering the recess 11 and on rotating of the standards will lock the same against accidental vertical displacement. The standard immediately above engagement with the table leaf is offset laterally as at 21 and then is turned upwardly providing a vertical portion 22. Either of the standards E or F may be inserted in any of the four corners of the table so that as the patient may be moved from one position to another, the knee rest standards may be adjusted without inconvenience to the patient.

The provision of the lateral offset portion 21 in the standards allows a greater degree of lateral adjustment of the knee rests than is possible with the present form of standards, which are vertical. without any such offset portions.

Furthermore, the provision of the lateral offset portion 21 of the standards E and F enables the spreading of the knee rests to a greater distance than that of the width of the table, thus enabling the use of a table which when folded may be readily portable.

Knee rests G and H are provided, made preferably of aluminum and each consists of two portions 23 and 24 which are hinged at 25. Each of the portions 23 and 24 is con cave on its inner side so as to receive a knee of a patient and support the same comfortably. The hinging of the portions 23 and 24: allows relative angular adjustment should a case arise for increasing comfort in supporting a patients knees. Each of the knee rests is provided on the portion 23 with a lateral lug 26 having an aperture 27 therethrough inclined with respect to the surface of the portion 23 for receiving one of the standards E or F. The rests are secured in vertical adjustment on the standards by set screws 28.

The rests G and H are vertically and angularly adjustable on the standards E and F and also the standards E and F are angularly adjustable with respect to the points of support of the same in the table so that a patient may be comfortably supported on the same. Each of the standards E and F is provided with a sliding block 30 which is adjusted vertically on the portion 22 of the same by means of a set screw 31. The block carries a leg strap 32 which may be adjusted about the'legs of a patient when the same are on the knee rests G and H, where it is necessary to strap the legs to the rests.

Hand straps 33 are attached to rings 34- which surround the lower end 19 of the standards E and F adjacent the upper surface of the sections A and B when extended. The oflset portions 21 of the standards prevent upward movement of the rings 34 when pressure is applied thereto by the patient.

A portable light K is provided with a metallic end portion 34 having a bifurcated lower extension 35 for engaging over a thumb screw 36 which may be threaded into a threaded opening in flanges of the section A for removably securing the light K to the table. The light K includes a flexible gooseneck 37 which carries at its free end the bulb 38 which is protected by a hood and reflector 39 so as to direct the light rays in one direction. The positive terminal 18 is provided with a connector plug 17 for cooperating with the battery C as before described and as illustrated in Figure 3. The negative terminal 40 is provided with a spring clip 41 which may be readily attached to any part of the table, standards, or knee rests for closing circuit through the bulb 38.

The light K may be positioned on any of the screws 36 as above described, or may be engaged over one of the set screws 28 which adjustably secure the knee rests G and H on the standards E and F. The end portion 34 is grounded so that as soon as any metallic portion of the table and accessories is touched by the end portion 3% the bulb 38 will light even though the negative terminal clip 41 is 7 not engaged. Should it be desired to use the .to allow considerable light for exploratory examination, then it may be removed from the screw 36 and the negative clip terminal 41 engaged on any part of the metallic structure whereupon the bulb 38 will light and the same may be used for exploratory purposes, the terminals 18 and 10, of course, being of sufiicient length movement of the light K.

Figures 1 through 4 show the table opened and with the accessories attached thereto for use in an obstetrical case or surgical purposes or for examination purposes.

Figure 5 illustrates the sections A and B folded and inserted in a container L which is similar to an ordinary suit case and shows in dotted lines the extended positions of the knee rests G and H when the same are packed between the folded sections A and B. The standards E and F as well as the light K and the

straps

32 and 33 are also packed between the folded sections A and B so that the structure, when folded, is compact and contains everything necessary for setting up a fully equipped obstetrical table at the place of use.

A surgical table made in accordance with this invention may be readily carried from place to place by the visiting physician and quickly set up for use. All of theparts being of metal enables the table and its accessories to be sterilized completely and. the

straps are made of such material as to enable complete sterilization of the same Without destroying the same.

A surgical table made in accordance with this invention may be carried for out patient cases and when set up provides everything that the best equipped in any hospital provides for such cases.

The battery C is a dry cell such as may be purchased anywhere and when one of these becomes played out a new one may be inserted for the exhausted one.

The standards E and F, as before stated, may be rotated about the points of support of the same in the table to accommodate the position of the knee rests G and H to suit the comfort of the patient in accordance with the position of the patient as desired by the physician. It will be observed that either standard may be readily removed from any one of the corner holes in which it is inserted and applied to any of the others, thus enabling quick adjustment of the patients body on the table should occasion arise.

The invention has been described herein more or less precisely as to details, yet it is to be understood that the invention is not to be limited thereby, as changes may be made in the arrangement and proportion of parts and equivalents may be substituted without departing from the spirit and scope of the invention.

The invention is claimed as follows:

1. I11 combination, a table, a standard on the table, a surgical knee support comprising a rigid exposed limb-joint fitting surface, and means on a side of said support adjustably mounted on said standard for adjustable supported connection of said knee support.

2. In a surgical knee rest comprising a pair of leaves, for connection to a common terminal connector, a leaf having means on a side thereof for connection with a standard for the support of said rest.

3. A surgical knee rest comprising a pair of hinged leaves, one of said leaves having an apertured boss on a side thereof for adjustable supported connection of said rest on a a standard.

4:. A surgical knee rest comprising a rigid exposed limb-j oint fitting surface and having means on a side thereof for adjustable supported connection of said rest on a standard.

In testimony whereof I have hereunto subscribed my name at Chicago, Cook County,
