Definitions
- the invention relates to a ball joint for a device for accelerating jaw growth with a ball joint head and an associated ball joint shell, which are attached to the ends of a spring rod and to holders connected to the teeth of the upper jaw and / or lower jaw.
- the object of the present invention is therefore to remedy these disadvantages and to improve the device in such a way that it can be used in a variety of ways and is easy to handle. In addition, it should be easy to vary with simple means and be inexpensive to manufacture.
- the object of the invention is achieved in that the ball joint heads and the ball joint shells are detachably connected to one another and to the spring bar and to the holders. This results in a configuration which makes it possible to attach the ball joint heads or shells to the spring bars as desired, depending on the intended use, with both the length and the strength of the spring force of the spring bars being able to vary. They can therefore be used variably as required.
- the joints as such are also releasably connected to one another so that the ball joint heads and the ball joint shells can be easily detached from one another.
- the ball joint heads or ball joint shells are detachably attached to the holders connected to the teeth.
- the spring core of the spring rod is the element that applies the forces required to accelerate the growth of the jaw. Therefore, the relevant part of the ball joint is sensibly connected to the spring core.
- the spring core has a suitable bore, which can also be provided with a thread.
- Different spring bars of different lengths and different spring strengths can be available as an assortment, which have corresponding holes.
- the respective ball joint half i.e. the ball joint shell or the ball joint head furthermore have a groove or a bead, the groove or the bead being able to be connected to the sleeve of the spring bar which surrounds the spring core.
- the inside of the sleeve can have a corresponding opposite to the connection with the groove or the bead of the ball joint half.
- the sleeve can also be connected via its tension in connection with the groove or the bead on the joint half.
- the dimensions and the forces should be designed in such a way that a sealing connection is created between the respective ball joint half and the sleeve, so that no oral fluid reaches the spring core and the screw.
- the joint half that is to say the ball joint shell or the ball joint head, which is connected to the spring bar, advantageously has a preferably cylindrical extension piece, to which the screw is connected and which has the groove or the bead.
- the hinge part that is connected to the holder, that is respective ball joint head or the ball joint shell also have an extension piece, which is also preferably cylindrical there.
- the screw In order to fasten the screw to the respective ball joint part or to the extension piece, the screw has a head which is inserted in the ball joint part or the extension piece in a rotationally and thrust-resistant manner.
- the ball joint part which is connected to the holder preferably has a rod at right angles to the longitudinal axis of this ball joint part for releasable connection to the holder.
- at least one tubular eyelet is attached there, the opening of which matches the cross-sectional dimension of the rod.
- Both the rod and the inside of the eyelet can have an angular, preferably rectangular or square cross section, so that the ball joint part is also secured in the direction of rotation about the longitudinal axis of the rod. This is particularly important if the spring bar is arranged between the upper and lower jaw, because the position of the ball joint head in the ball joint shell can be defined so that the ball joint is not jammed.
- a safety device for releasably connecting the ball joint head to the ball joint shell and securing it. hit, which includes a safety slide and a matching slot-like recess in the ball joint shell.
- the safety slide is preferably shaped like a fork and the middle region of the fork has a recess which is adapted to the corresponding part of the ball joint head.
- This middle part therefore preferably has a surface that corresponds to a part of a spherical joint shell, which of course only partially encompasses the spherical joint head, since the fork-like opening of the securing slide must engage behind the spherical joint head.
- the slot-like recess in the spherical shell is advantageously provided on the opposite side of the shell opening with two openings into which the fork ends of the locking slide are fitted.
- the locking slide is firmly held in the slot-like recess and in the two openings for the fork ends.
- the safety slide can furthermore have a notch, recess or the like on the area facing away from the fork-shaped end, which serves for easier handling of the slide slide with a tool.
- FIG. 1 an overall perspective view of a ball joint
- FIG. 2 a side view of a ball joint head
- FIG. 3 a perspective side view of a locking slide
- FIG. 4 a section through a ball joint shell according to line IV -
- 1 denotes a ball joint which has a ball joint head 2 and a ball joint shell 3.
- Both the ball joint head 2 and the ball joint shell 3 have extension pieces 4, which are preferably are cylindrical and are integrally formed on the ball joint head or on the ball joint shell.
- This rod 5 can, as explained in the general description, be inserted into eyelets which are inserted on holders or brackets which are attached to the teeth of the lower or upper jaw of the patient, so that a firm hold of the ball joint head on the Holder or bracket is ensured. Securing of the rod 5 in the eyelet can, if necessary, be effected simply by slightly bending the free end of the rod after insertion into the eyelet.
- a screw 6 is inserted in the extension piece 4 of the ball joint shell 3 and is inserted in the extension piece 4 in a rotationally and thrust-resistant manner by means of its head 7.
- the spherical joint shell is connected to a spring rod, not shown, the screw being screwed into a bore or opening in the spring core of the spring rod.
- the extension piece 4 of the ball joint shell 3 has on its circumference - this is also shown in FIGS. 1 and 4 - a groove 8 which can be brought into operative connection with a sleeve of the spring bar.
- the sleeve has a bulge on its inner surface that snaps into the groove, or the sleeve is elastic and its dimensions are adjusted so that it partially penetrates into the groove when pushed onto the extension piece, thus creating a sealing connection. is posed.
- the spherical joint shell has a slot-like recess 9, in the extension of which two openings 10 are provided.
- 11 denotes a safety slide which is fork-shaped.
- the safety slide 11 has a recess in the central region designated by 12, which is adapted to the ball of the ball joint head 2, so that after the safety slide is inserted into the slot-like recess 9, the ball of the ball joint head 2 is secured in the ball joint shell 3.
- the fork ends 13 of the safety slide 11 extend into the openings 10 of the ball joint shell and are supported there.
- a notch 14 is also attached to the safety slide 11, by means of which the safety slide can be removed from the ball joint shell.
