Abstract

A root canal irrigation assembly, comprising a vacuum device, a suction element having an elongate suction tip, and a sonic device having a sonic handpiece for introducing sonic vibrations into the suction element and thus causing the suction tip to vibrate, wherein the rear end of the suction element is connected to the vacuum device such that an irrigation fluid containing tissue residues and/or bacteria can be suctioned out of a root canal. The suction element comprises an internal vibrator which is held in the suction tip and projects out of the front end thereof, wherein the suction tip and the internal vibrator are interconnected at their rear ends, wherein the suction tip is resiliently formed and dimensioned such that, when the suction tip is introduced into a root canal, the suction tip sealingly closes the root canal in the region of the root canal wall.

Dependent claims

A dental root canal irrigation arrangement for cleaning dental root canals of a patient, comprising:

a vacuum device (2);
a suction element (5) with an elongated suction tip (6), which is at least partially made of a flexible material and is positioned at a front end of the suction element (5);
and
a sonic device having a sonic handpiece (15),
wherein a suction channel (7) is formed in the suction element (5), which extends from a rear end of the suction element (5) in the direction of its front end into the suction tip (6),
wherein the suction tip (6) has at least one suction opening (8) which opens into the suction channel (7),
wherein the rear end of the suction element (5) is connected to the vacuum device (2) via a conduit (9), so that a rinsing liquid with tissue residues and/or bacteria contained therein can be sucked by a vacuum generated by the vacuum device (2) via the at least one suction opening (8) into the suction channel (7) and via the latter to the vacuum device (2),
wherein the suction element (5) has an inner oscillator (6a) extending through the suction tip (6) and protruding out of the front end thereof,
wherein the inner oscillator (6a) is hollow,
wherein the suction tip (6) is configured elastically and dimensionally to be introduced into a dental root canal,
wherein the suction element (5) is detachably attached to a distal end of the sonic headpiece (15) so that sonic vibrations generated by the sonic headpiece (15) may be introduced into the suction element (5) to cause the suction tip (6) to vibrate,
wherein the suction tip (6) and the inner oscillator (6a) are connected to one another at their rear,
wherein the suction element (5) has a connecting part (11) that comprises an attachment device for releasably attaching the suction tip (6) at the sonic handpiece (15),
wherein the conduit (9) is connected to the connecting part (11) and a suction canal section (7a) is formed in the connecting part (11),
wherein the suction tip (6) and the inner oscillator are (6a) each fixed at their rear to the connecting part (11) and are connected to one another,
wherein the inner oscillator (6a) engages the suction channel section (7a) and is fixed there to the connecting part (11).

13 more elements

A suction element for sucking irrigation liquid from a dental root canal of a patient to be cleaned, comprising an elongated suction tip (6) which consists at least partially of a flexible material and is positioned at a front end of the suction element (5),

wherein the suction element (5) has a suction channel (7) which, starting from a rear end of the suction element (5), extends in the direction of the front end thereof into the suction tip (6), and wherein the suction tip (6) has at least one suction opening (8) which opens into the suction channel (7),
wherein the suction element (5) has an inner oscillator (6a) extending through the suction tip (6) and projecting out of the front end of the suction tip (6), and
wherein the inner oscillator (6a) is hollow,
wherein the suction tip (6) is configured elastically and dimensionally in such a way to be insertable into a dental root canal,
wherein the suction tip (6) and the inner oscillator (6a) are connected to one another at rear ends thereof,
wherein the suction element (5) has a connecting part (11) that comprises an attachment device for releasably attaching the suction tip at a sonic handpiece (15),
wherein a conduit (9) is connectable to the connecting part (11) and a suction canal section (7a) is formed in the connecting part (11),
wherein the suction tip (6) and the inner oscillator (6a) are each fixed at the rear ends thereof to the connecting part (11) and are thereby connected to one another, and
wherein the inner oscillator (6a) engages a suction channel section (7a) and is fixed there to the connecting part (11).
