Definitions
- the invention concerns a head and chin rest for face-down operations and is especially directed to the need both for patient comfort and for convenient access by the an- esthesiofogist to the nose and mouth.
- the patient head In face-down operations with the patient either in a prone or prone sitting position, the patient head is commonly turned to the side even though this puts the cervical spine into an abnormal position and often leaves the patient with a sore neck after a long operation-

- the head When the patient is in a prone position, the head can be positioned face-down on an annular cushion that rests on a support cantilevered from the head end of the operating table.
- the prone sitting position requires a kneeling attachment to be fastened to the foot of the operating table, and to use an annular cushion would require a hole to be formed in the bed of the operating table.

Abstract
face-down operations, a head and chin rest comprises a base (10), a cushioned forehead support (12) pivotably mounted on the base, and a cushioned chin rest - (14) telescopically cantilevered from the forehead support by a pair of thin metal rails (15). This affords both comfortable support for a patient's head and also excellent access to the patient's nose and mouth. Extending from the base are the ends of a generally U-shaped rod (22) to prevent the head and chin rest from tipping.
Description
- The invention concerns a head and chin rest for face-down operations and is especially directed to the need both for patient comfort and for convenient access by the an- esthesiofogist to the nose and mouth.
- In face-down operations with the patient either in a prone or prone sitting position, the patient head is commonly turned to the side even though this puts the cervical spine into an abnormal position and often leaves the patient with a sore neck after a long operation- The sidewise head position constricts the trachea and larynx, thus tending to produce throat soreness when there is a tube in the patient's throat When the patient is in a prone position, the head can be positioned face-down on an annular cushion that rests on a support cantilevered from the head end of the operating table. However, the prone sitting position requires a kneeling attachment to be fastened to the foot of the operating table, and to use an annular cushion would require a hole to be formed in the bed of the operating table.
- The operating table of U.S. Patent No. 2,577,177 has "a concave head rest 31 to engage the forehead of a patient" (col. 4, lines 52-53) which enables the head to be face-down and also provides-good access to the nose and mouth. U.S. Patent No. 3,289,674 shows in Fig. 1 a similar forehead cushion 108, but both of those head rests leave the chin unsupported, thus producing a lordotic curve in the cervical spine and resulting in problems similar to the consequences of turning the head sidewise. A head rest which is similar except being pivotably supported is shown in "Chick Surgical Table CST Series SE 2001, "a brochure of Chick Surgical Systems, Professional Medical Products, Inc., Greenwood, SC, USA.
- The present invention concerns a head and chin rest for face-down operations which allows the patient's head, chin and neck to be comfortably supported in a natural position while affording excellent access to the nose and mouth. Like the head rest of the Chick brochure, that of the invention comprises a base and a forehead support pivotably supported by the base. The novel head and chin rest differs from that of the Chick brochure by having
- a pair of thin rails by which the chin support is telescopically cantilevered from the forehead support to provide an adjustable spacing between the forehead and chin supports while affording good access to the mouth and nose between and around the rails.
- The telescopic cantilevering permits the chin rest to be moved in and out to fit heads and faces of various sizes and then locked in position. By pivoting the forehead support, the patient's chin can be raised or lowered relative to the forehead. The base should extend beneath the chin support and includes resilient feet allowing it to stand oh a flat operating table surface.
- Preferably each of the forehead and chin supports includes a rigid frame or platform to which a contoured cushion may be removably attached. Each cushion may be a foamed plastic carrying a layer of repositionable pressure-sensitive adhesive on its lower face. The cost of the cushions should be sufficiently low to permit them to be disposable after each operation. While the base and the rigid frames or platforms may be metal for cleanliness, they can be wholly or partly molded plastic at significantly lower cost, thus possibly allowing for economical disposability.
- In the drawing, each figure of which is schematic;
- Fig. 1 is a perspective view of a first head and chin rest of the invention; and
- Fig. 2 is a perspective view of a second head and chin rest of the invention.
- The head and chin rest shown in Fig. 1 has a
rigid base 10 pivotably supporting arigid forehead support 12. Aclamp 13 cooperates with hidden detents to prevent the forehead support from pivoting until it is unlocked. Arigid chin support 14 is cantilevered from theforehead support 12 by a pair ofmetal rails 15 which telescopically fit into knurledlocking nuts 16 that project from theforehead support 12. Thelocking nuts 16 permit the rails to be locked at infinitely differing spacings between the forehead and chin supports. Each of the forehead and chin supports has a rigid concave frame orplatform 18 formed from sheet metal and into which are fitted disposable contouredcushions base 10 are the ends of a generally U-shapedrod 22 which extends beneath thechin support 14 to prevent the head and chin rest from tipping. Thebase 10 and itsrod 22 have sixresilient feet 24 allowing the head and chin rest to be stably positioned on a flat operating table. Fixed to the sides of eachconcave frame 18 are twohooks 26 for securing the straps of an anesthetic mask being worn by the patient - In a prototype of the head and chin rest shown in Fig. 1, the
concave frames 18 were formed from stainless steel having a thickness of about one mm, and each of thecushions - The head and chin rest of Fig. 2 has a
rigid base 28 on which arigid forehead support 29 is pivotably mounted at ahinge 30. Fixed to arigid chin support 32 are a pair ofmetal rails 34, each of which telescopically fits into a knuriedlocking nut 36 that projects from theforehead support 29, thus cantifevering the chin support from the forehead support The forehead and chin supports have flat platforms on which are mountedcontoured cushions cushions base 28 is a U-shapedrod 42 which extends beneath thechin support 32. - Fixed to each side of the
base 28 is a soft-metal sector plate orprotractor 44 that can be clamped at any point along itsarcuate perimeter 45 by aknurled nut 46 projecting from the side of platform of theforehead support 29. Not shown are a pair of closely spaced, case-hardened steel pins which have been pressed into holes in each side of the platform immediately beneath theknurled nut 46. When the knurled nuts are tightened, the tips of the steel pins bite into the inward-facing surface of the softer protractor to guard against slippage under the weight of the patient's head. In a prototype of the head and chin rest of Fig. 2, each steel pin had a length of about 5 mm, a diameter of about 1.5 mm, and a rounded tip which protruded about 0.5 mm beyond the surface of the platform. - The head and chin rest of Fig. 2 has a low profile that permits the upper-chest-support cushion to be quite low and hence both inexpensive and laterally stable. The height of the patient's head above the operating table is adjustable by stocking the
cushions 38 and 40 in various thicknesses.
