Kollin ABSTRACT: Traction cradle device comprising a standard, formed with a toothed rack and adapted to be secured to the back of a patient's chair, means for applying pressure to a patients occipital area and to both sides of a patients jaw area and shoulder-restrainer means for maintaining stability of the shoulders while pressure is being exerted upward on a patients jaw-occipital area, first adjustable means for securing said occipital and jaw pressure-applying means on said standard and second adjustable means for securing said shoulderrestrainer means on said standard.

PATENTED Au 3 1911 IN VENTOR. JOSEPH D. CORCORAN MAW ATTORNEY TRACTION CRADLE DEVICE BACKGROUND OF THE INVENTION The invention relates to traction devices in general and in particular to a traction cradle device for the specific extension or traction of the cervical upper dorsal area of the spine.

A principal object of the invention is to provide a cradle in which the head may rest with pressure applied to the occipital area as well as both sides of the jaw area.

Another object of the invention is to provide shoulder restrainers which will maintain stability of the shoulders, while pressure is being exerted upward on the jaw-occipital area.

A further object of the invention is to provide a means of applying traction and at the same time fit any and every head size possible. I

Yet another object of the invention is to eliminate the confinement which the patient feels in presently known types of traction devices.

Still another object of the invention is to provide application of traction with a minimum of adjustment necessary for such procedure.

Yet another object of the invention is to eliminate the socalled hanging which is involved in all types of traction and to increase substantially the confidence of the patient upon the first application of the device.

Still another object of the invention is to vary the amount of traction that can be applied, so precisely and so gradually, that it will produce a complete sense of relaxation and provide a very secure feeling for the patient, while eliminating all discomfort.

With the above and such other objects of the invention which may hereafter more fully appear, the invention consists of the novel constructions, combinations and arrangements of parts as will be more fully described and illustrated in the accompanying drawing.

It is to be understood that the device is not limited to the construction and arrangement of parts disclosed and that changes, variations and modifications in the detail construction and arrangement of parts may be resorted to within the scope of the invention.

In the drawing:

FIG. 1 is a side elevational view of the device according to the invention;

FIG. 2 is a top plan view thereof;

FIG. 3 is a partial cross section taken on the line 3-3 of FIG. 1 and FIG. 4 is a cross section taken on line 44 of FIG. 2.

Referring now to the FIGS. in detail, the traction device according to the invention comprises a vertical standard 6 formed with a rack 8. The standard 6 is secured to the backrest 10 by means of a bracket 12. Slidably mounted on standard 6 are a pair of housings l4 and 16 provided with rotatable pinions l8 and 20, respectively, engaging with the rack 8. The

pinions

18 and 20 are operable by means of a pair of respective shafts secured to the pinions and knobs integral with the free ends of said shafts. One of said shafts and its knob 24 is shown in FIG. 2. Both housings are provided with setscrews 26, 28, for securing the housing in desired positions on standard 6.

Rigidly secured to the housing 14 is an elongated, horizontally extending flat member 30. A pair of arcuate prongs 32, 32', contoured to the shape of the inferior bone structure of the head are pivoted with their rear end portions 33, 33' by means of pivot pins 36, 36', rigidly secured to said end portions, in member 30. Each pivot pin is provided with a threaded end 38 and a wingnut 40 engaging therewith. The prongs may thus be displaced laterally and secured in desired positions by tightening the Wingnuts 40.

Secured to the rear end portion 33, 33' by means of hinges 42, 42' are a pair of rear occipital cushions 44, 44' which adapt themselves to the contour of the seated patients occiput as the lift is applied by raising the member 30.

Slidably mounted on the forward ends 46, 46' are sleeves 48, 48'. A pair of chin cushions 50, 50' are secured to these sleeves by means of hinges 52, 52'. The chin cushions 50, 50'

can thus be adjusted forward or backward by moving the

sleeves

48, 48 while the chin cushions swing on the

hinges

52, 52, so that said chin cushions adapt themselves to the shape of the bone structure of the chin when coming in contact with the chin.

Secured to the sleeve 48' is one end of a band 54 of Velcro material, while a pad of Velcro material 56, engageable with the free end of band 54 is secured to the sleeve 48.

Velcro material is made of a multitude of short filaments of synthetic plastic such as hylon, which are adapted to mesh with and interlock against a material made also of a multitude of short wirelike filaments which are shaped to become hooked to like materiali Such materials are presently available under the commercial name of Velcro manufactured by the Velcro Corporation New York, N. Y. when the chin cushions 50, 50' are brought under the patients chin, the Velcro band is led under or around the forward part of the chin, depending on the shape of the bone structure of the chin, and the free end of the band 54 is hooked to the pad 56. This prevents the cushions from spreading apart as pressure of the cradle is exerted upward.

To prevent the chin cushions 50, 50' from assuming a vertical position, the backs of the chin cushions are provided with spacers 58 which maintain the chin cushions in inclined positron.

To maintain the stability of the shoulders while pressure is being exerted upward on the jaw-occipital area there is provided an adjustable shoulder-restrainer mechanism. This mechanism comprises a horizontal member 60 rigidly secured to housing 16 and a pair of

adjustable bars

62, 62 provided with longitudinal slots 64, 64' at one of their ends. As shown in FIGS. 1 and 2 the bars are displaceable longitudinally and swirigable laterally of threaded studs 66, 66' which are integral with the housing 16. Wingnuts 68, 68' serve to secure the bars 62, 62' in the required position.

Secured to each of the free ends of the bars 62, 62' by means of a ball-joint fastener 70, arcuate bars 72, and helical springs 74 are a pair of shoulder-restrainer pads 76, such as shown in FIG. 3.

To apply traction, the patient is seated and the shoulder pads 76 are emplaced on the patients shoulders by raising or lowering the housing 16 and adjusting the

bars

62, 62. The setscrew 28 and the Wingnuts 64, 64' are tightened. The housing 14 is elevated until the

occipital cushions

44, 44 adapt themselves to the occipit. The chin cushions 50, 50' are adapted to the shape of the patients chin by moving

sleeves

48, 48 into an appropriate position. The Velcro band is passed around or under the forward part of the chin, depending on its shape or the bone structure. Traction is applied by elevating the cradle to the extent considered necessary, by turning the respective knob.

The traction device according to the invention eliminates all discomfort to the patient. It also makes it possible to ascertain exactly which group of vertebrae are best extended. Heretofore, traction devices lifted the head without knowledge as to where the actual stretching of the vertebrae was taking place. Furthermore, the patient can move his head forward if desired and bring about an immediate release from the pressure that is being applied. F

The head cradle is applied to an easy manner, in contrast to all former types of traction. It is shaped with its cushions, so that equal pressure will be applied at all contact points during the application of traction. The equal'points of contact are brought about by the raising or lowering of the chin so as to equalize the chin, occipital cushionpressure.
