Abstract

A hand-held device, particularly for dental purposes, comprising a dispenser for dispensing a pasty filling material as well a device for emitting a radiation that causes the filling material to cure.

Claims (17)

1. Hand-held device comprising:

a dispenser for dispensing a pasty filling material; and

an emitter located on the hand-held device for emitting radiation that effects hardening of the filling material,

wherein the dispenser comprises an outlet nozzle located on a front end of the hand-held device,

the outlet nozzle is part of a compacting element that can be subjected to sonic or ultrasonic oscillations via a drive unit located in the hand-held device,

the outlet nozzle is formed in such a manner that the filling material is dispensed laterally with respect to a longitudinal axis of the hand-held device,

the emitter is formed in such a manner that with regard to the longitudinal axis of the hand-held device the emission of the radiation is effected in an offset manner with respect to the dispensing of the filling material, and

the emitter is formed in such a manner that with regard to the longitudinal axis of the hand-held device the emission of the radiation is offset rotationally about the longitudinal axis of the hand-held device by approximately 90° relative to the outlet nozzle.

2. Hand-held device as claimed in claim 1 , wherein the emitter comprises a light source.

3. Hand-held device as claimed in claim 2 , wherein the light source comprises an LED or laser diode.

4. Hand-held device as claimed in claim 1 , comprising a modeling tip, which can be attached to the outlet nozzle, for working the filling material, wherein the modeling tip can be subjected to sonic or ultrasonic oscillations via a drive unit located in the hand-held device.

5. Hand-held device as claimed in claim 4 , wherein the modeling tip has a conical shape.

6. Hand-held device as claimed in claim 1 , comprising an adjuster for adjusting the viscosity of the dispensed filling material.

7. Hand-held device as claimed in claim 1 , comprising means for selectively opening and closing a dispensing channel for the filling material.

8. Hand-held device as claimed in claim 1 , comprising a plurality of storage containers for filling materials having different properties and selection means for selectively dispensing one of the filling materials.

9. Hand-held device as claimed in claim 8 , wherein the selection means includes a first adjusting ring disposed in a front region of the hand-held device and a second adjusting ring on the hand-held device aft of the first adjusting ring.

10. The hand-held device of claim 9 , wherein the first adjusting ring selectively opens and closes a dispensing channel leading from one storage container in the plurality of storage containers to the outlet nozzle and the second adjusting ring controls an oscillation generator connected to the hand-held device to vary viscosity of the pasty filling material.
