Definitions
- the present invention relates to a dental handpiece and more particularly to an air polisher device.
- the injection nozzle forms a given angle with the longitudinal axis of the tool which, by definition, is determined during its manufacture in the factory.
- this predetermined angle is not necessarily in conformity with the specific morphology of the different patients and with the usual handling type of the practitioner, so that sometimes the latter are hampered in use of the instrument. Even if this angle is suitable for the practitioner for a specific type of intervention, it may sometimes be totally inappropriate for another type of work and / or a different patient.
- the object of the present invention is to remedy this drawback by proposing an air polisher tool enabling its user to bring it into conformity with the specific morphology of its patients and with its own handling modes, for each type of intervention determined, and this without this change in conformation has a practical influence on the flows delivered.
- the present invention thus relates to a dental air polishing tool of the type comprising a body and a nozzle, the latter being intended to spray under pressure, onto teeth to be polished, an abrasive powder surrounded by a jet of liquid, characterized in that the nozzle comprises three deformable elements, namely: a first tubular element forming an axial and longitudinal internal channel,
- tubular element concentric and external thereto
- third tubular element, or spacer element which is disposed between the first two, which is pressed, substantially over its entire length, against them and which is provided longitudinal channels allowing circulation of fluid from its posterior end to its anterior end, these three elements being capable of being bent and straightened, at least one of them being capable of ensuring the maintenance of the other two in the bent or straightened position which has been communicated to him.
- the element capable of ensuring the maintenance in position will be the external tube.
- the three elements will form a removable sub-assembly, which will allow the practitioner to proceed easily to sterilize this part of the instrument.
- Figure 1 is an axial and longitudinal sectional view of a spray nozzle disposed in a handpiece of an air polisher according to the invention.
- Figure 2 is an enlarged cross-sectional view of the spray nozzle shown in Figure 1 along line II-II thereof.
- Figure 3 is an axial and longitudinal sectional view of an alternative embodiment of the spray nozzle shown in Figure 1.
- Figure 4 is a partial schematic view in elevation on a reduced scale of a spray nozzle according to 1 invention.
- FIGS 1 and 2 There is shown in Figures 1 and 2 an air polisher instrument 1 according to the invention which is intended to take place in a handpiece 2, shown schematically in Figure 1, and which allows the practitioner to ensure the grip of the instrument.
- the front part thereof ends in a nozzle 3, which is pierced by an axial and longitudinal channel 7 in which is fixed a metal tube 9, or external tube, which extends outside the nozzle 3 on a certain distance 1 ⁇ .
- the internal face of the external tube 9 receives a spacer element 11, which is made of an easily deformable material which, in addition to its qualities in the field sanitary, must also be able to withstand the temperatures required by an autoclave treatment, such as for example FEP (fluorinated ethylene propylene) PTFE (polytetrafluoroethylene), and whose external face is hollowed out with longitudinal grooves 13 which extend over its entire length and which constitute with the internal surface of the tube 9 longitudinal channels.
- the spacer element 11 is hollowed out with an axial channel 8 which receives a central tube 10 which is in good contact with the latter.
- the outer tube 9 is preferably made of stainless steel which has undergone a thermal annealing operation so as to give it a good capacity to undergo deformation and to retain it thereafter, after the stress at which it has submitted has ceased. It is known that the deformation of tubes by bending is a delicate operation which requires proven instruments and techniques under penalty of causing an angular crushing of the tube.
- the spacer element 11 disposed between the two outer 9 and central 10 tubes in fact performs two functions, namely a first technical function of maintaining these two concentric tubes at a constant and determined spacing, this which is favorable to a regular flow of the fluids delivered, and a second function which is to transmit from one tube to the other any deformation which is applied to one of them and in particular from the external tube 9 towards the central tube 10 , which ensures a regular curvature of the tubes and avoids the aforementioned angular crushing phenomenon.
- the external tube 9 will be made of a material of good deformability capable of retaining the deformation which has been applied to it after the deformation stress has ceased, this role could also be assigned to the central tube 10, possibly to the two tubes 9 and 10 or even also to the spacer element 11.
- the nozzle 3 of the polisher may include means for making it easily removable, especially at the end of sterilization.
- Such a nozzle 3 is thus formed in the example shown in the figure of a tubular rear part 3a which is extended forward by a cylindrical part of larger diameter 3b and which ends in a frustoconical front part 3c.
- the latter receives the external tube 9 inside which the spacer element 11 and the central tube 10 are disposed.
- the nozzle 3 comes to be embedded in an obviously cylindrical shape which is provided in the front part of the handpiece 2.
- the supply of the central channel (not shown in the drawing) is, for example, provided from the rear part of the nozzle 3 and that of the annular channel is provided by a radial hole 12 which opens into it and which is in communication with a channel 14 provided in the body of the handpiece 2.
- the spacer element 11 can be made of a material such as annealed stainless steel, capable of retaining, after the stress has ceased, the angle ⁇ which will have been given to it by bending.
- the outer 9 and central 10 tubes can be made of a flexible and elastic material such, for example FEP or PTFE.
