Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to head and chin supports for prone surgery, and more particularly to head and chin supports that maintain patient comfort and allow anesthesiologist access to the nose and mouth. Regarding support.

BACKGROUND OF THE INVENTION Prone surgery with the patient in either a prone position or a prone sitting position often places the patient's head, neck vertebrae in an abnormal position and leaves the patient with a sore neck after a long surgery, but usually Can be bent sideways. The lateral head position tends to tighten the trachea and larynx, thus creating a sore throat when there is a tube in the patient's throat. When the patient is in the prone position, the head may be placed prone on an annular cushion resting on a support cantilevered from the head end of the operating table. However, the prone position requires a knee bending attachment to be secured to the foot of the operating table, and the use of an annular cushion requires that holes be formed in the bed of the operating table.

A similar problem occurs as a result of bending in the direction. A similar head support, except that it is pivotably supported, is available from Chich Surgical Systems, Professional Medical Products, Greenwood, Kauskarolina, USA.

DISCLOSURE OF THE INVENTION The present invention provides head, jaw and neck surgery for prone surgery that allows the patient's head, jaw and neck to be comfortably supported in a natural position while providing excellent access to the nose and mouth. Regarding support. According to the present invention, a head and chin support for supporting a patient in a prone position includes a base that is stably supported on a horizontal surface, and a base that is mounted on the base and that is flat, respectively. a rigid forehead support and a rigid chin support having flat pedestals; and a small rigid block-like cushion having substantially perpendicular sides and removably positioned over each of said flat pedestals. and a recess recessed inwardly from two adjacent sides of each of said cushions, said recess of said cushion for the forehead approximately corresponding to the entire forehead of a prone patient. and the recess of the chin cushion is contoured to substantially conform to and support the entire chin of a prone patient. , further comprising an adjusting device for adjusting the spacing between the platform and the cushion for the forehead and the platform and the cushion for the chin to allow sufficient access to the patient's face when the patient is lying prone; A pivoting device for pivoting the frame to raise and lower the platform for the chin relative to the platform for the forehead is provided. Preferably, the invention includes a pair of narrow rails that telescope from the forehead support to support the chin support in a cantilevered manner so as to provide good access to the mouth and nose between and around the rails. It is equipped with

The telescoping cantilever support allows the chin rest to be moved in and out to fit heads and faces of various sizes and then locked in place. By pivoting the forehead support, the patient's chin can be raised or lowered relative to the forehead. The base must extend beneath the chin support and have elastic feet to allow it to stand on a flat surgical table surface.

Preferably, each of the forehead and chin supports includes a rigid flume or platform to which a contoured cushion is removably attached. Each cushion may be a foamed material with a repositionable layer of pressure sensitive adhesive applied to the underside. The cost of the cushion must be low enough to allow the cushion to be disposed of after each surgery. The base and rigid frame may be metal for reasons of cleanliness, but may also be entirely or partially molded resin to allow for significantly cheaper and therefore perhaps economical disposables.

Example The head and chin support shown in Figure 1 is a rigid forehead support 1.
It has a rigid base 10 which supports 2 in a pivotable manner. The clamp 13 cooperates with a hidden rotation stop to prevent the forehead support from pivoting until released. Rigid chin support 14 is cantilevered from forehead support 12 by a pair of metal rails 15 that telescopically fit into knurled locking nuts 16 projecting from forehead support 12. The fixing nut 16 allows the rail to be fixed at infinitely different spacings between the forehead support and the chin support. The forehead support and the chin support each have a rigid concave frame or platform 18 formed by sheet metal, with disposable contoured cushions 19, 20 attached to the frame 1.
8 respectively. The cushion 19 has a recess contoured to approximately match and support the entire forehead of the patient who is lying on his stomach, and the cushion 20 has a recess that is contoured to approximately match and support the entire forehead of the patient who is lying on his stomach. It has a contoured recess. These recesses are located in the two portions of each of the cushions 19 and 20.
It is recessed inward from two adjacent sides. The end of a generally U-shaped rod 22 extending below the chin support 14 is secured within the opening in the base 10 to prevent the head from tilting. base 10
The rod 22 has six elastic feet 24 to enable the head and chin support to be stably positioned on a flat operating table. Two hooks 26 for securing the straps of the anesthesia mask worn by the patient are fixed to the sides of each concave frame 18. Note that the knurled fixing nut 16 constitutes an adjusting device.

In the prototype head and chin support shown in FIG.
It was 20 pounds of polyurethane foam without any coating.

The head and chin support of FIG.
0 and is pivotably mounted to the base 28. A pair of metal rails 34 are secured to the rigid chin support 32, each rail telescopically fitting into a knurled locking nut 36 projecting from the forehead support 29, thus cantilevering the chin support from the forehead support. support.

Each of the 0s may be a block of resin, eg polyurethane foam, with a layer of pressure sensitive adhesive that can be installed when attaching it to the stand. A U-shaped rod 42 extending below the chin support 32 is secured to the base 28.

A soft metal sector plate or protractor 44 is attached to the base 2.
8 and may be tightened at any point along the arcuate periphery 45 by knurled nuts 46 which protrude from the sides of the base of the forehead support 29. A pair of closely spaced case hardened steel pins, not shown, are pushed into holes in each side of the platform directly below the knurled nuts 46.
When the knurled nut is tightened, the point of the steel pin bites into the soft inward facing surface of the protractor to protect it against slippage under the weight of the patient's head. In the head and chin support prototype shown in Figure 2, each steel pin has a length of approximately 5 mm, a diameter of approximately 1.5 mm, and a rounded tip that projects approximately 0.5 mm beyond the surface of the platform. There is.

The head and chin support of FIG. 2 has a low profile which allows the upper chest support cushion to be quite low and therefore inexpensive and laterally stable. The height of the patient's head above the operating table is adjustable by providing cushions 38, 40 of various thicknesses.
