Abstract
A device for use in an endodontic treatment, for example for filling a root canal of a tooth that is empty as a consequence of the removal of the nerve, with a thermoplastic product such as gutta percha, which product is distributed in the root canal by means of heating and pressing. The device includes a housing that can be grasped by hand, a treatment element provided at one end of the housing, and a device for making the treatment element vibrate.
Claims32
Device for use in an endodontic treatment, for example for filing a root canal of a tooth that is empty as a consequence of the removal of the nerve, with a thermoplastic product such as gutta percha, which product is distributed in the root canal by means of heating and pressing, which device comprises a housing (1) that can be grasped by hand, a treatment element (2) provided at one end of the housing, and means (10-12) for making the treatment element (2) vibrate, characterised in that there is a vibratory unit (10-12) in the housing (1), which vibratory unit (10-12) is provided with coupling means (16) by means of which the treatment element (2) is coupled to it, as well as with a vibration generator (10-12).
Device according to one of the preceding claims, wherein the coupling means (16) and the treatment element (2) form a snap-fit connection.
Device according to one of the preceding claims, wherein a switch (4, 5) is provided which is made up of two contact layers (5) between which resilient spacer elements are located, such that when a pressure is exerted said contact layers (5) can be brought into contact with one another, with compression of the spacer elements.
Device according to claim. 13, wherein the two contact layers (5) extend around the complete periphery of the housing (1) and are covered by a flexible ring (4).
Device according to one of the preceding claims, wherein an electrical power source (6) is provided in the housing (1) for heating the tip of the treatment element (2).
In combination, a device according to one of the preceding claims, comprising a housing (1) that can be grasped by hand, a first treatment element (2) provided at one end of the housing (1) and a vibratory unit (10-12) in the housing (1) for making the treatment element (2) vibrate, and a second treatment element provided with cutting or melting means, which first and second treatment elements can be fixed to the housing (1) as desired.
