' INVENTOR. HHNS GA 7 BY 7:2- J
DEVICE FOR PRODUCING X-RAY PICTURES OF TEMPOROMANDIBULAR JOINT BACKGROUND OF THE INVENTION Until now a special X-ray machine was required to take X-ray pictures of the human temporomandibular joint. These pictures, though an integral part of dental treatment, are only inconveniently supplied to the average dental practitioner by institutions where such machines can be found.
This standard procedure produces an interrupted treatment program bothersome to patient and dentist. It should also be mentioned that the X-ray pictures obtained should be reproducible in order to obtain maximum benefit. This quality controlis difficult to achieve when various operations may be taken the X-ray pictures at various times within a given institution.
The present inventation will allow the dental practitioner to take reproducible X-ray pictures of the temporomandibular joint in his own dental office.
SUMMARY OF THE INVENTION Hence, it will be seen from what has been stated above a problem still exists in the art of dentistry in furnishing the dentist in a convenient fashion with X-ray pictures of the temporomandibular joint of his patients. It is a primary objective of this invention to provide an auxiliary device which facilitates the making of such X-ray pictures.
Another and more specific object of the present invention is directed to a novel construction of a device rendering possible the convenient and rapid making of X-ray pictures for a dentist.
The invention is predicated upon the recognition that for the purpose of producing X-ray pictures, especially X-ray pictures of the temporomandibular joint, it is possible to resort to the use of a conventional dental X-ray machine.
Still it has been found that when using such conventional dental X-ray machines certain problems arise. For instance, it is difficult to obtain thecorrect adjustment of theX-ray tube with respect to the head of the patient, or the correct adjustment of such X-ray tube with respect to the X-ray film as well 'as the correct supporting of these components with regard to one another is difficult. i
Hence a further objective of the present invention is the provision of a device which positively ensures in a most-simple manner the desired proper adjustment and support of the aforementioned components.
Now, in order to implement these and still further objects of the invention, which will become more readily apparent as the description proceeds, the auxiliary device of the invention suitable for the production of X-ray pictures of the temporomandibular joint is manifested by the features that there is provided a bracket which is provided with a film holder or support as well as means for securing the bracket to the dental X-ray machine. The securing means is arranged at the bracket in a position opposite the film holder or support.
BRIEF DESCRIPTION OF THE DRAWING The invention will be better understood and-objectives other than those set forth above, will become apparent when consideration is given to the following detailed description of the enclosed drawings.
FIG. 1 is perspective view of a preferred embodiment of inventive device suitable for the production of X-ray pictures, especially the human temporomandibular joint.
FIG. 2 is a front view of the device of FIG. 1 shown attached to the conical nose portion of a conventional dental X-ray machine.
DETAILED DESCRIPTION OF INVENTION The following description refers to the enclosed drawings of the invention. A mounting bracket 1 formed of any suitable arcuate curved member, here considered as formed of metal bent intoflan are as shown. One end of the bracket '1 is equipped with a clamping ring 2 and the opposite end is equipped with a film holder or support 3. The clamping ring 2 is connected in any convenient fashion, for instance by screws 9, with the bracket 1. To provide an adjustable mounting or support of this auxiliarydevice at the X-ray machine the clamping ring 2 has a slot 10 through which passes a clamping screw 11, or equivalent device, which may be provided with a knurled head as shown. The ends of the clamping ring 10 which are formed by this interruption are provided with a suitable enlarged portion, not particularly shown, in order to obtain, on the one hand a support or contact surface and, on the other hand, a nut member for the clamping screw 11. It has been found that the above mode of attachment of the auxiliary device to the X-ray machine is extremely simple and reliable, although it will obviously suggest itself to those skilled in the art that modifications of the described attachment or securing means for the bracket are possible.
It will be recalled that a film holder is mounted at the bracket 1 at the end remote from the attachment means constituted by the clamping ring 2 and clamping screw 11, and this film holder or support 3 consists of a frame 13 and two guide tracks or rails 14 and 15 which are secured to such frame 13 in a position confronting one another in spaced relationship as shown. Apart from the foregoing structure the device also possesses an adjustable stop or impact means 4 comprised of a bolt member 5 which is displaceably mounted at the bracket 1 and a contact or bearing disc 6 which is secured to'on'e'e'nd of this bolt 5.;The surface of the contact disc 6 is disposedperpendicular-to the lengthwise axis of the bolt 5 and this bolt 5 is mounted at the bracket 1 in such a manner that its axis is directed outside of the center of the arcuate-shaped bracket 1, as particularly well seen by referring to FIG. 2.
Continuing, it will be observed that a guide bushing or sleeve 7-is secured to the bracket 1 in axial alignment with the bearing bore at the bracket 1. Guide bushing 7 is equipped with an adjustment or positioning screw 8. Hence the bolt 5 extends both through the non-illustrated bearing bore as well as through the guide bushing or sleeve 7. Its desired position can be regulated by means of the aforementioned adjustment screw 8. The adjustable stop or impact means 4 serves for adjusting the entire apparatus 1, '18 at the head of the patient. The impact means 4, as already explained, is elevationally adjustable, permitting a desired regulation of the 'X-ray machine with respect to the portion of the head of the patient which is to be photographed, i .e., X-rayed. When the contact disc 6 .comes to bear upon the head of the patient, then, the bolt 5 is disposed vertically and since the axis of the bolt 5 is directed outside of the center of the arcuate-shaped bracket 1 there results an inclination of the outlet for the central X-ray beam so that the X-rays travel at a certain angle with respect to a horizontal plane.
During practical use of the device it is of advantage if the X-rays also extend at a certain angle with respect to the frontal plane disposed before the face of the patient. For this purpose the face of the contact disc 6 as viewed from the top is provided with lines or notches 16. These lines 16 permit controlling the adjustment of the device with respect to the frontal plane considered above. The two previously discussed angles have been predetermined advantageously at In FIG. 2 the invention is illustrated as attached to the dental X-ray machine. It will be observed that a cassette 17 is located at the film holder 3, this film cassette or magazine 17 being retained in desired position by the guide rails 14 and 15. The clamping ring 2 is attached to the outlet portion of the dental X-ray machine 18 which is equipped with the conical member or nose 12. The surfaces of the film cassette 17, the disc 6 and the front surface of the cone 12 represent those surfaces which come to bear against the head of the patient.
While the preferred use is described, it is to be distinctly understood that the invention is not limited thereto but may be otherwise variously utilized and practiced within the scope of the following claims accordingly,
