Abstract
An applicator for dental compounds includes a shaft, the front end of which can be connected with the aid of a fastening device to a syringe containing the dental compound, and a plunger. The shaft contains a ram for advancing the plunger. The fastening device has an inner sleeve, attached to the shaft, and an outer sleeve, attached on the inner sleeve rotatably with respect to it. The inner sleeve is substantially cylindrical and has such a cavity that its cross section is substantially U-shaped. Clamping takes place as a result of eccentricity.
Claims13
An applicator for a syringe containing a dental compound and having a plunger for expelling the dental compound from the syringe, the applicator comprising:
- a shaft having a front end;
- a ram extending longitudinally within the shaft, the ram being adapted for advancing the plunger to expel the dental compound from the syringe;
- and
- a fastening device disposed at the front end of the shaft, the fastening device including
- an inner sleeve attached to the shaft, the inner sleeve being substantially cylindrical and defining a longitudinally extending cavity, the inner sleeve having a substantially U-shaped cross-section, and
- an outer sleeve rotatably attached to the inner sleeve, the outer sleeve having a substantially wedge-shaped projection extending into the cavity of the inner sleeve, the outer sleeve being rotatably movable between an insertion position and a holding position;
- wherein the cavity of the inner sleeve is adapted for eccentrically receiving the syringe when the outer sleeve is in the insertion position and the outer sleeve projection is adapted to exert a clamping force on the syringe when the outer sleeve is rotated to the holding position.
A system for applying a dental compound comprising:
- a syringe adapted to house the dental compound, the syringe including a plunger adapted to expel the dental compound from the syringe;
- and
- an applicator including
- a shaft having a front end;
- a ram extending longitudinally within the shaft, the ram advancing the plunger to expel the dental compound from the syringe;
- and
- a fastening device disposed at the front end of the shaft, the fastening device including
- an inner sleeve attached to the shaft, the inner sleeve being substantially cylindrical and defining a longitudinally extending cavity, the inner sleeve having a substantially U-shaped cross-section, and
- an outer sleeve rotatably attached to the inner sleeve, the outer sleeve having a substantially wedge-shaped projection extending into the cavity of the inner sleeve, the outer sleeve being rotatably movable between an insertion position and a holding position;
- wherein the cavity of the inner sleeve eccentrically receives the syringe when the outer sleeve is in the insertion position and the outer sleeve projection exerts a clamping force on the syringe when the outer sleeve is rotated to the holding position.
