Definitions

  • the present invention relates to irrigation procedures in the dental field, more particularly to irrigation procedures into the root canal and under the gum with an irrigating cannula or an equivalent device.
  • trrigants sodium hypochlorite solution (disinfectant, antibacterial agent) and ethylenediaminetetraacetic acid, widely abbreviated as EDTA solution (tissue-dissolving, removal of the smear layer, chelating agents),
  • Periodontai disinfection of the gums also plays a major role in the treatment of gingivitis (inflammation of the gums) or periodontitis (inflammation around the tooth), in such cases, an irrigation procedure below the gum line in inflammatory or infected formed space is recommended.
  • the most frequently used irrigants are hydrogen peroxide or chlorhexidine.
  • Such irrigation usually takes place through a rinsing cannula (or a dental irrigating needle) connected to a fluid delivery system (e.g. a syringe).
  • a fluid delivery system e.g. a syringe.
  • Another aim is to provide a device that is cheap enough to be single use, that may be sterilized and that is universal (i.e. It may be used with different delivery systems).
  • the invention concerns cannula for a dental irrigation spray system:, wherein said cannula comprises at least a closed tip at its distal end and at least a set of three radial orifices located near said tip of said cannula.
  • the radial orifices of the first set are clearly separated from each other to spread all around at 360° and are on the same plane or a different one.
  • the cannula comprises at least a second set of radial orifices.
  • the radiai orifices of the second set are clearly separated from each other to spread all around at 360° and are on the same plane or a different one.
  • the radial orifices of the first set have the same size than the radial orifices of the second set or a different size.
  • the tip has a spherical shape or another shape for occlusion of the treated zone.
  • the cannula comprises a channel connected to said radial orifices for delivery of a product.
  • the cannula is flexible.
  • the cannula has a conical shape.
  • the cannula is connectab!e on a spray recipient or a bottle.
  • the cannuia is combined with connection system such as a Luer Lock connector.
  • the cannula is preferably made from a thermoplastic material, such as PE or PP.
  • the invention concerns an irrigating system comprising at least a cannula as defined herein.
  • the irrigating system comprises a spray can on which the cannula is connected.
  • the spray uses the "Bag on Valve” (BOV) technology,
  • the invention concerns an irrigating procedure using a cannuia as defined herein or an irrigating system as defined herein. Accordingly, in one embodiment the present invention defines a cannula suitable for the irrigation process described herein with improved properties over the prior art devices and also a spray system using said cannula.

  • Figure 5 illustrates another embodiment of the invention in a perspective view
  • Figure 6 illustrates a general perspective view of an embodiment of the invention
  • Figures 7 and 8 illustrate possible exemplary uses of the present invention.
  • Detailed description of the invention in a first embodiment illustrated schematically in figures 1A to 1 D, a cannula 1 according to the invention comprises the following aspects and features.
  • the cannula 1 has preferably an elongated shape with a closed tip 2 at its distal end and a plurality of radial orifices 3 (see figure I D).
  • the cannula 1 may be straight as illustrated or it may have another shape (for example with a bend).
  • the several (preferably at least three) radial orifices 3 are close to the distal end 2, and they are preferably located on a same plane and clearly separated from each other to spread all around at 360° in order to reach the best spraying effect.
  • the openings 3 may be on the same plane with respect to the axis of the cannula 1 or a different one as will be explained iater by reference to other embodiments of the invention.
  • Figure 2 illustrates a perspective view of the distal end of the cannula 1 with its tip 2 and the openings 3 distributed around 360°.
  • the cannula 1 comprises a channel 4 through which the product to be delivered by the cannula 1 may flow.
  • the channel 4 is connected to the openings 3 at its distal end and at its proximal end connected to a supply of product (see for example figure 6).
  • Figure 3 illustrates another embodiment of the cannula 11.
  • the tip 12 comprises a distal end 5 with a different shape than in previous embodiments: here the end 15 has a spherical shape to form an occlusion zone of the apex at the distal end of the tip 12. This occlusion zone is useful to protect the apical foramen of the tooth being treated for example from the irrigation solution being applied with the cannula.
  • the shape is not limited to a spherical shape and other shapes are possible: oval etc. depending on the teeth being treated and the patient's characteristics. !n the embodiment of figure 3, the openings 13 also have a greater size in the axial direction than in figures 1A-1 C and 2 forming so-called vents.
  • Figure 4 illustrates another embodiment of the cannula 21 ,
  • the cannula 21 comprises two sets of openings, a first set 22 near the end of the distal tip 23 of the cannula 21 and a second set on a proximal side of the tip 23.
  • Each set 22, 24 preferably comprises three openings equally distributed over 360°, as described above for the preceding embodiments. This embodiment allows delivering more products (for example a solution) to the treated zone and at different locations or solutions that have to be mixed at the application site etc.
  • each set is represented in an exemplary manner in figure 4 and other sizes are possible (different sizes for each set, etc) and also the openings of each set may be in the same plane or a different one.
  • Figure 5 illustrates another embodiment of a cannula 31 according to the invention.
  • the cannula 31 comprises three openings 32 at the distal end 33 of the cannula 31 and the distal tip 34 has a spherical shape as in the embodiment of figure 3 for similar reasons.
  • the shape of the distai tip may be different than illustrated and this principle is applicable to other embodiments described herein.
  • Figure 6 illustrate one possible use of the cannula described herein (applicable to all embodiments of said cannula 1 , 11 , 21 , 31 ).
  • the cannula 1 may be mounted on a recipient 5, for example a spray can 5.
  • Connection means 6 are to be provided, typically standard means such as Luer-Lock systems and other equivalents.
  • Other features and characteristics of the cannuia of the invention are listed hereunder:
  • It can be sterilized and is suitable to deliver the desired products in the desired environment.
  • It has preferably a conical shape with the apical third of adequate diameter to get close to the apical foramen and to allow backfiow of the irrigant without generating excessive pressure
  • It is preferably flexible to follow the shapes of the treated part (e.g. curved root canal), without causing injury.
  • a recipient e.g. spray can 5 see figure 6 or bottle
  • FIGS 7 and 8 illustrate a possible use of the cannula 1 , 11 , 21 , 31 described above. These figures illustrate images of the use of the cannuia with a spray can 5 (figure 6) and show clearly three side liquid jets exiting the openings as described above. in these illustrative examples of use, the invention thus forms a spray system (see figures 6, 7 and 8) with the following aspects and features,
