Definitions

• the present invention relates to an aspirating retractor mirror adapted to the field of odontology and oral care.
• dentists traditionally use in the mouth, in addition to the actual working instrument (turbine, manual instrument, ultrasonic insert ...) on the one hand, a single-use saliva pump having the function of eliminate fluids and debris (saliva, blood, spray from the turbine ...) and secondly a mirror mounted at the end of a rigid handle whose function is to remove soft tissues (lips, cheeks, tongue ) so that the practitioner has a satisfactory direct or indirect view of the work area.
• a mirror thus connected by the saliva pump to the suction device fitted to the dental chair allows a satisfactory vision of the work area taking into account that the fluids and debris are constantly sucked.
• Such a mirror can not be entirely satisfactory in that its implementation is relatively long and inconvenient because it requires three separate manipulations of removing the filter tip fitted to the saliva pump, to connect the mirror to the end of it and connect the saliva pump to the suction device on the dental chair.
• a mirror thus designed can not fulfill the function of spreading the soft tissue during work given the flexible nature of the saliva pump which is generally constituted by a plastic tube reinforced by a brass wire.
• the elasticity of the saliva pump also causes it to be rapidly deformed by the action of the patient's cheeks, tongue and lips, and it is frequently necessary to remove it from the mouth to restore its original shape.
• the object of the present invention is to remedy these drawbacks by proposing an aspiring spacer mirror enabling the dentist to work with only two instruments in an efficient and continuous manner, which corresponds to him for a considerable advantage.
• such an aspirating spacer mirror is characterized in that it consists of an annular piece having a concavity at its inner part surrounding a reflecting surface and extending by a tubular end as well as by a rigid tubular handle intended for be connected by one of its ends or first end to the suction device fitted to a dental chair.
• the annular piece, the tubular endpiece and the tubular handle may constitute a one-piece assembly.
• annular piece and the tubular end on the one hand and the tubular sleeve on the other hand are constituted by two distinct elements so that the tubular handle fits on the tubular endpiece.
• Such a suction retractor mirror can, without departing from the scope of the invention, be disposable or sterilizable and reusable. It may for example be made of metal or plastic material by casting.
• the reflective surface must then be added during an additional step of gluing, crimping ...
• the annular piece and / or the tubular handle can (advantageously) be stiffened (és) by a reinforcing thread.
• the suction retractor mirror according to the invention constitutes a sufficiently rigid assembly to allow it to spread effectively and thus to protect the soft tissues of the work area, and simultaneously to facilitate visual access to this area by sucking fluids and debris after working in the mouth.
• the concavity of the annular piece may not be continuous but interrupted by a few (as a rule four or five) radial tabs to strengthen its structure, to maintain the reflective surface more effectively and to better distribute the peripheral suction (fluid mechanics, Venturi and Torricelli effects).
• This annular piece may also advantageously be equipped with small transverse grooves defining channels to bring to the surface of the mirror water and saliva that accumulate, especially when the practitioner works on the mandible.
• the suction spreading mirror object of the invention is indeed more effective than the amount of water on the surface of the mirror is important.
• the reflecting surface is generally circular in shape but can also be oval, polygonal ...; this reflecting surface may advantageously be constituted by a magnifying mirror or a double-sided mirror, which increases the brightness inside the mouth and ensures the practitioner a better working comfort.
• this reflecting surface can of course vary without departing from the scope of the invention; this surface has as a rule a radius of 18 to 25 mm.
• suction on the surface is all the more effective as the perimeter of the annular piece is reduced.
• the section of the annular piece which circumscribes the reflecting surface may also be any without departing from the scope of the invention (circular, triangular, pear-shaped ).
• the rigid tubular shaft is equipped at its second end contiguous to the tubular end of a shoulder delimiting an extension of smaller section for receiving a spacer accessory whose function is to isolate the working field from the patient's tongue, soft tissues and saliva.
• such a spacer accessory is advantageously constituted by a bent leg equipped at one of its ends with a positioning ring intended to be placed around the extension of the tubular handle, and at its opposite end of an auxiliary mirror including circular shape. In the working position, such an auxiliary mirror must extend substantially parallel to the reflecting surface of the annular piece.
• the annular piece is equipped on its periphery with a series of small through-holes.
• the outer surface of the tubular handle comprises flats so as to facilitate its gripping.
• This tubular sleeve may for example have a hexagonal section. It can of course also have a circular section without departing from the scope of the invention.
• the outer diameter of the tubular shaft at its free end corresponds to the internal diameter of the suction device equipping the dental chair.
• the junction of the tubular shaft and the annular part ensures a perfect continuity of the vacuum to the periphery of the reflecting surface, thus a satisfactory suction of fluids and debris.
• the aspiration of the dental equipment is indeed distributed directly to the entire reflecting surface.
• the suction spreader mirror according to the invention therefore allows the practitioner to have a particularly simple and practical tool able to simultaneously and effectively perform the functions of retrorever mirror and saliva pump and allowing him to perform a work in progress. continued.
• the characteristics of the aspirating spacer mirror which is the subject of the invention will be described in more detail with reference to the appended nonlimiting drawings in which:
• FIG. 1 is a perspective view of a suction spreader mirror not equipped with a scale spreader accessory 2
• FIG. 2 is an enlarged view of the annular piece

• Figure 4 is a perspective view similar to Figure 1 but showing the spreader mirror equipped with a spacer accessory.
• FIG. 5 is an "exploded" view corresponding to FIG. 4.
• the suction spreading mirror is constituted by an annular piece 1 surrounding a circular double-sided reflective surface 2 and extending through a tubular nozzle 3 having a shoulder 4 delimiting an extension 5 of smaller section.
• the extension 5 of the tubular end piece 3 allows the fitting of this endpiece on a rigid tubular handle 6.
• the rigid tubular handle 6 is intended to be connected by a first of its ends 7 to the suction device equipping a dental chair not shown.
• the outer diameter of the tubular shaft 6 at its free end 7 corresponds to the internal diameter of the suction device.
• the tubular handle 6 comprises at its middle part a section 8 having an octagonal section so as to facilitate gripping.
• the rigid tubular shaft 6 is equipped at its second end by which it fits on the tubular tip 3 of a shoulder 9 defining an extension 10 of smaller section for receiving an accessory spacer 1 1 shown in Figure 4, the configuration will be described in more detail later in this presentation.
• the annular piece 5 in which the reflecting surface is forcibly held has an inverted U-shaped section closed at its upper part and has a concavity 12 at its inner part so as to define an annular chamber to this level.
• the suction from the dental chair shown by the arrow A in Figure 3 is distributed directly to the inner portion of the annular chamber 12 and optimally distributed at the periphery of the reflecting surface 2 which n ' is not shown in Figure 3, through the tubular shaft 6 and the tubular nozzle 3 so as to rid the surface 2 debris and fluids during dental care.
• the annular part 1 is further equipped with a series of small transverse grooves 13 which define channels of a nature to transfer water and saliva that accumulate at the level of the reflecting surface 2.
• the annular piece 1 is also equipped at its periphery with through holes 14 to prevent the accumulation of water and saliva on the reflecting surface 2. These holes 14 can suck the saliva and fluids or debris that can accumulate on the periphery of the work area and disturb the patient and the practitioner.
• the spacer accessory 1 1 is constituted by a bent leg 15 equipped with an open positioning ring 16 at one of its ends and a circular auxiliary mirror 17 at its opposite end. .
• the positioning ring 16 is put in place around the extension 10 of the tubular handle 6.
• the auxiliary mirror 17 is in turn disposed parallel to the reflecting surface 2 of the annular piece 1.
