Abstract

With a dental apparatus comprising several instruments (8) connected to a power supply panel (11) by helicoidal flexible lines (4) fixed at the upper level (2) to the apparatus, and provided at the lower level (6) with a rack for the instruments (8), it is desired to have the possibility of easily withdrawing each instrument from the rack or of putting it back into the rack without moving the other instruments. It is proposed to locate the power supply panel at the top level (2), to provide each supply flexible line with an individual anchoring point to the apparatus, situated in its connection to the power supply panel, to give each flexible line a helicoidal shape along its entire length between the power supply panel at the top level and the instrument kept at the lower level (8), to render the helicoidal portion of the supply flexible line between the connection panel and the instrument substantially rectilinear, when at rest, and slightly inclined with respect to the vertical, and to sling the instruments in notches in the rack (5) by means of elements of appropriate shape (9) located at the extremity of the supply lines adjacent to the instruments or on the instruments themselves.

Description

Dental treatment device

The invention relates to a dental treatment device according to the Preamble of claim 1.

To return the lines to the non-use position of the handpieces appropriate location and provision of a sufficient length of these lines In the position of use facilities have already been proposed which the necessary Effort to avoid sagging and thus the treatment of disruptive supply lines to decrease.

A known device (DT-OS 1628080) is used for this purpose the supply line for part of its length through a cylindrical screw fender supported at the exit point of the supply line from a carrier part is attached facing upwards and when moving the Hondstückes in its position of use As a result of deflection in the removal direction, a restoring effect is generated. These The facility is characterized by relatively little effort, however, it has the disadvantage that it is unavoidable in practice Remove a handpiece in a different direction than parallel to the one in the rest length of the handpieces spanned by the supply lines by an overshoot the spring when a handpiece is put back, the neighboring handpieces and, if applicable other neighboring facilities could be endangered.

Another known device (DT-AS 2026839) overcomes this disadvantage in that the supply line is on part of its Lan3e by means of a swivel arm is performed, on which a restoring force acts, which has a directional component, which, when deflected in the above-described way, causes an uncontrolled and swinging the arm in or opposite to the respective removal direction prevented. But it also requires a greater amount of resilient and moving red parts.

The object of the invention is to provide a dental treatment device specify, while avoiding the disadvantages described of the Expenditure on resilient and moving red parts, as well as equipment for guidance the supply lines between their connections and the instruments are dispensable is.

The object set is achieved according to the invention in that A device is proposed which has the features of claim 1.

The inventive interaction of the arrangement and choice of The shape of the supply lines are mutually exclusive in known devices exclusive advantages of a return of the supply lines without additional moving device parts on the one hand and avoiding the endangerment of neighboring handpieces or other red parts due to uncontrolled swinging of a return device on the other hand achieved at the same time.

Another advantage is that the return of a Supply line even then without endangering neighboring handpieces or parts of the device happens when a handpiece in any direction within a wide Range is taken, although on specially trained mechanisms for directional Repatriation was waived.

This means that additional steps are required with the least possible effort of the practitioner with a temporary change of his position with which he Correct the position of a known type of device without directional feedback would have to.

The proposed device thus combines the respective advantages, which has one or the other known device and avoids one in the patient a certain streaking effect can arise from parts of the device that are unexpectedly Be set in motion towards the patient.

In addition, the device according to the invention enables the waiver on all devices that are rigid or moved under the action of restraint forces for guiding the supply lines between their connections on a supply part and the instruments.

In particular, it is characterized by the fact that the ease of use known devices with simpler and thus more cost-effective means guaranteed will.

When arranging a device according to the concept of the invention on a height-adjustable Swivel arm, this can be moved close to the patient's head.

This results in extremely short reach for the dentist. The removal and returning an instrument to its non-use position requires this no more attention than would be necessary with an instrument hanging freely in the room.

Details of the invention and advantageous developments are in The following is explained with reference to the drawings.

1 shows the spatial position proposed according to the invention and assignment of supply part (11), instrument support (5), supply lines (4) and their fixed points (1) on the supply part in a preferred embodiment.

For the sake of clarity, not all supply lines are included The arrangement of 5 instruments does not restrict the subject matter of the invention Less or more instruments can just as easily be provided.

From their fixed points (1) on the support part (11) on the upper level (2) Starting from the treatment device (3), the supply lines (4) almost run straight with a slight inclination to the vertical for the instrument holder (5) on the lower level (6).

The instrument holder (5) can according to FIG. 1 slots (7) for receiving the instruments (8) have or be designed differently, for. B. in shape of appropriately curved round or flat material.

Another option is to have a separate one for each instrument Provide shaped part and the individual mounts formed in this way next to one another to line up. This would make the arrangement of more or less instruments in more economical Wise come in handy. With these individual brackets you can edge on the per se Types of preparatory switching functions for the provision of working media and / or Energy triggered for the instrument removed from the respective individual holder will.

Correspondingly designed molded parts (9) at the end of the hose on the instrument side or on the instrument itself enable the instruments to be suspended from the bottom pointing instrument heads. The use of molded parts to hold the instruments enables the individual mounts to be manufactured economically, as these are not must be adapted to the different dimensions of different instruments.

To secure the position of the instruments and to guarantee a A support (10) is provided for easy access to the instruments supports the instruments in a slightly inclined position.

Through a suitable arrangement of the instrument holder (5) and support (10) can of course also be achieved that the instruments do not - as shown - lie in one level, but are fanned out against each other.

In addition to the hanging arrangement, this improves the grip of the instruments. For the formation of the support (10) apply mutatis mutandis to the instrument holder (5) indicated design options, including the possibility of providing individual supports in order to alternatively use those mentioned above trigger the preparatory switching functions.

Fig. 2 shows a detail of an example of an alternative design the support (10) in the form of a correspondingly curved round material. Farther Another possibility of designing the molded parts (9) is shown in FIG. 2. It consists in a substantial part of the last turn of a supply line is stiffened, so that the instrument is carried by this last turn.

The resilient effect of the helically coiled supply lines (4) brings it back from a position of use to the position of non-use the instruments are without additional resilient and moving parts.

As already mentioned, the device can be close above the patient's head be placed. Immediately after removing an instrument from its holder thus arises due to the inventive arrangement of the supply lines and from the aforementioned restoring effect through their resilient design in the form of a helix Coils partially relieve the dentist's hand from the weight of the instrument, because this is contrary to the direction of action of the restoring force downwards to the treatment area is introduced.

To achieve a perfect location and regular arrangement of the supply lines are the ends of the helically coiled ends on both sides Supply lines designed concentrically to the helix.
