HEADREST FOR OPERATING TABLES Filed Aug. 10, 1948 Patented May 23, 1950 UNITED STATES PATENT OFFICE HEADREST FOR OPERATING TABLES- Charles F. Eaton, Salem Depot, N. 11., assignor to Eaton Appliance Corporation, Salem, N. H., a. corporation of New Hampshire Application August 10, 1948, Serial Nmsaeic '7 Claims.
This invention relates to a head rest for supporting the head of a patient on an operating table. When an operation is to be. performed on some parts of the head of a patient, such as the skull r ear, for example, it has been found difficult to support and maintain the head in a suitable position for access to the particular part to be operated on. According to. the present invention, a support is provided which is simple, rugged, and easily adjustable to hold the head in a variety of positions. best suited for different operations.
For a more complete understanding of the in vention, reference may be had to the following description thereof and to the drawing, .of which-,-
Figure 1 is a front elevation of ahead. rest embodying the invention;
Figure 2 is a, side elevation of the same;
Figure 3 is a fragmentary, sectional view on the line 33 of Figure 2;
Figure 4 is a fragmentary, sectional view, showing a modified form of the invention;
Figure 5 is a perspective view of the head rest,
showing a different position of adjustment; and
Figures 6, 7 and 8 areelevational views, showing various ways in which the head rest can be used.
' Thehead rest illustrated on the drawing comprises a base i0 whichispreferably in the form of a flat, rigid plate having lateral extensions l2 and I4 which are bent up to form vertical uprights at opposite sides of the base plate ll Attached to the uprights l2 and I4 are side plates I6 and I8 which may be similar to each other in structure so that a description of one will serve also for the other. Each of these side plates is provided with a boss 20 projecting from its inner face, the boss having a central hole 22 which is screw-threaded to receive the threaded shank 24 of a screw 26 having a knurled head to serve as a finger piece. The boss 20 is cylindrical and fits in a hole 30 through the corresponding upright l2 or [4 so that each plate can be angularly adjusted about the axis of its boss. Each side plate is clamped in adjusted angular position by the screw 24, the head of which engages a washer 32 which extends over the inner end of the hole 30 and bears against the inner face of the corresponding upright. A washer 34 of some frictional material, such as rubber, leather or the equivalent, is interposed between the outer face of the upright and the abutting inner face of the side plate so that when the bolt is set up tightly by manipulation of the finger piece 26, the side plate is firmly gripped. This feature is, of great practical importance, since a surgeon must be sure that there will be no unexpected shiftv inthe position of the head-sup porting member when a delicate operation is in progress.
The. upper edge of each side plate i strai ht and normally horizontal. This edge is prefera ly provided with a. rounded bead 36over which passes an end portion; of a band 40 of soft, resilient material such as sponge rubber or'the like. This band. is preferably of a width substantially equal. to the length of the upper edge of a side plate. Asindicated injFigure 1;, the band 4i! spans the space between the. side plates l6 andt8, the ends of the band being anchored against the outside races. of the. side plates. For convenience in anchoringthe. ends of the band 49, each end maybe clamped. between two metal strips 42. and. ,these. metal str ps be drawn toether, by a suitable number of screws 46. The plate 42 projects beyond the end. or the band an. andis provided with one or more holes to receivescrews 5.0..two such screws being shown-in Figure. 2., Thejscrews to have knurled heads and threaded shanks, the latter passing freely through holes in. the: metal strip 412: for threaded en agement in holes: in; the side. plate. as indica d: i Figured Ifazfirmer-supnortis desired than that afiorded. by the soft band 40. a stiff r p 5 of semi-rigid. material... such: as a metal. like aluminum, a synthetic plastic material, or an equivalent, is mounted under the band 40 so as to extend over and around the beads 36 of the side plates. To ensure adequate stability of the head rest when in use, the base I0 is extended in one direction substantially beyond the head-supporting band 40, as indicated in Figures 2, 6 and 7. This elongation of the base prevents the device from tipping over either toward or away from the patient, and such stability is an additional safety factor.
In assembling the head rest, the stifiening plate 52 is first mounted on the side plates I6 and I8, and the band 40 is thereafter secured in place by fastening one end to one of the side plates and then stretching the band sumciently to bring the holes of the end strip 42 into registry with the screw holes in the other side plate so that the screws 5|] may be put in place.
In some cases, a greater degree of rigidity may be desired. In such case, a heavier plate 54, of metal or other rigid material, may be used instead of the semi-flexible plate 52, as indicated in Figure 4.
The head rest serves to elevate the head of the patient above the level of the operating table and to provide an easy, conveniently adjustable support therefor. By loosening the screws 24, one or both of the side plates can be rotatively ad- Justed, as indicated in Figures 5 and 6. In Figure 6, the patient is arranged on his side, the head being held in a substantially horizontal position, convenient for an operation on the patients ear. Figure 7 shows the head rest on a sloping portion of the operating table so as to hold the head in position for an operation on the nose. Figure 8 shows the use of the head rest to support the head of the patient'who is lying face down, in position for an operation on the back of the skull, the head rest being convenient for use with anaesthetizing apparatus which is'held in place by suitable harness 62 over the patients head.
