Description

Ultrasonic dental treatment device

The innovation concerns a TJitraBehall dental treatment device with one handpiece, which is in a pre-opening interchangeable Sinsatsspitssn and inside it contains a transmitter that carries the at the rear of the Hanästückes supplied via a cable electrical energy in mechanical oscillations converts and feeds the rear ends of the insert tips.

In the case of the previously known cream treatment devices, the Handpiece supplied during operation is sprayed through a nozzle. The continuous Flow-through of water is also required to that Cool the handpiece.

Because the water flow is constantly maintained must and also the handpiece has a relatively slim design required, a pedal switch has been used for the electrical control of the transformer,

However, this is disadvantageous for the dentist. Such safety adjustments on the handpiece usually have the shape of a lever which is provided in "a convenient position close to the drill on the handpiece. Actuating the switch does not cause any difficulties ₉ since the drill is generally always moved in the same direction". Such a lever switch device is, however, inconvenient in the case of ultrasound devices, since these are moved in many different directions during the treatment.

The aim of the liexi & rung is to solve the ^ orgenamtite problem so to solve that the switching device inside the handpiece 3 requires very little space and that the switching device can be in any desired position during the treatment The position can be switched on and off simply by using the thumb while the rest Be able to guide the handpiece in a fixed position »

In order to solve the above-mentioned task, there is an innovation

the arrangement made so, äa3 a »rear end of the Handstüclcea for the transformer an electrical switch is provided, which via a slide that remains longitudinally verse in the interior of the handpiece and one axially displaceable to a limited extent in an annular groove of the handpiece casing sleeve with the slide front end connected actuating ring can be operated

Further details and characteristics of the hiring result The detailed description can be found in the sequence of submissions and the attached drawing, in which one preceded Embodiment of Heueruag "is illustrated for example.

Bas in Pig. 1 handpiece shown, which consists of a rear part 52 and a front rope 36, anthslt in the rear rope 32 a seventh shown Transformer.

In a Yorderöffmiüg of the SanSetüekteile 36 canoe a replaceable insert 25 is inserted into a tip 10 will. A connection cable is provided at the rear of the handpiece to supply power to the transmitter. In the assembled state, a part of the IPassuag protrudes the tip into the transformer, vjelcher him Suggested electrical energy la mechanical vibrations implements, which of the tip 10 leads to «ground ·

In addition, aai handpiece is not shown in detail Wasserfeuhlumg Tor saw their water over a Siisenspitse 21a can emerge.

According to the Efeuertmg is an electrical Sehalter 15 for the transformer at the rear end of the handpiece behind a Xnnenhülse 28 _t which is concentrically surrounded by a Kantelhülse 32nd The jacket sleeve 32 forms the rear end of the handpiece and encloses the transmitter,

The switch 15 is designed sls Kikrosebalter, which cooperates with a slide 39, the longitudinally displaceable stored inside the Hanästücks and an actuating ring 38 is connected to its volumes remote from the switch. The actuating ring can be moved back and forth between stops, which are formed by the ends of an annular groove 37a of the handpiece

The entire handpiece is composed of a plurality of concentric sleeve parts · The front Htilsenteil 36 includes a reduced diameter portion, vm the rin ^ zn form 37a örmige groove in which the? Actuating ring 38 is mounted. The axial length of this section of reduced diameter corresponds to the intended actuation cylinder of the ring 38.

The inner sleeve 28 has a reduced diameter front portion 33 which is in the assembled condition in a quick front sleeve part 36 engages at the point where the reduced diameter section is provided «the inner tube is in this way with an annular shoulder surface 28a, at θ © 3? is to be assigned states the end of the shell part 37a forming the channel

is applied, so that then äie Sciralterfläche 28a as .Anschlag can serve for the actuating ring 38.

The inner sleeve 28, which is struck £ from the ifentelfcmlse 32 tsnfsüß has a Läegsrinne 34 for the switch actuation provided slide 39 on.

The slide 39 is attached to the inside of the actuation ring 38 ″. In order to allow the slide 39 to move freely, the sleeve part 37a is provided with a slot 37 aligned with a longitudinal channel 34.

The slide 39 feann a flat ribbon spring with a StSrte of "for example 0.5 nan, so that for the Installation of the switch <2as Eanästuek no enlarged Dimension required.

The outer diameter of the actuating ring 38 is two Easier to use & now slightly larger than the diameter of the handpiece.

The complete treatment device can be obtained from the Hanä des Zahnerstes to be grasped with all singing, whereby the Thumb is always able to operate the actuating ring 38 su with any orientation of the Sp * .tse 10 and to keep the device on and off.
