Abstract

A dental mirror assembly including a handle that allows the practitioner to hold the system and manipulate it in the oral cavity of a patient. A shaft assembly connects a motor within the handle to a gear box that transfers angular momentum to the mirror. The power to spin the mirror flows from the motor within the handle to the shaft. From there the power flows to a bevel gear and to then to a spinning mechanism, to spin the mirror. Switching mechanisms are used to switch the spinning mechanism.

Description

MIRROR ASSEMBLY FOR USE IN DENTISTRY
CROSS-REFERENCE TO RELATED APPLICATIONS [001 ] The present application claims the benefit of priority to US
Provisional Patent Application Serial Number 62/612,731 , filed January 2, 2018, entitled "mirror assembly for use in dentistry", the aforementioned application is hereby incorporated herein by reference.
TECHNICAL FIELD
The present invention relates to appliances useful in dentistry.
BACKGROUND ART The dentist's work entails carrying out surveying and active mechanical/surgical intervention in the patients' oral cavity. Small mirrors handled by the dentists and auxiliary staff members assist in viewing the nooks and crevices abundant in the oral cavity and more specifically in and around teeth/damaged teeth, jaws and gums. The oral cavity, especially during dental treatment is a wet, humid warm environment which is conducive to obscurity of the mirror. In US patent application 2016/0360957 discloses a dentists' mirror with a rotating mechanism which causes the mirror to rotate, in order to rid it of debris and humidity from the reflective surface. The rotation is brought about by power of the suction mechanism that dentists apply. In US patent application 2004/0076019 a rotatable dental mirror is disclosed in which the driving means supports the mirror directly from below.
The present application presents structurally and functionally leveraged mirror for ameliorating the effective functionality of a dentist's mirror during treatment of patients.

DISCLOSURE OF THE INVENTION
The mirror assembly in accordance with the present invention is referred to in Fig. 1. Handle 22 is module which allows the practitioner to hold the system, manipulating it within the oral cavity. It typically harbors a battery and a rotating electric motor. On/off Switch 24 facilitates activation or deactivation of the motor inside the handle. Mirror 26 has a reflecting side 26A shown in the figure. Mirror 26 is encased within mirror housing 28. Gearbox 32 is shown adjacent mirror housing 28. A drive shaft subassembly 34 connects between gearbox 32 and handle, or functionally speaking, to the motor concealed within handle 22 More structural features and functional properties are explained with reference to Fig. 2. Mirror 26 has its reflective side 26A facing outwardly from housing 28. Gearbox 32 is located between mirror housing 28 and shaft subassembly 34. Here it can be seen that the shaft subassembly 34 includes shaft 54 sheathed by shaft cover 56. Shaft 54 is revocable around axis 62 in either spin direction as indicated by double headed arrow 64
The power transfer system including gear
In accordance with the present invention, spinning of the mirror which takes effect in order to clear it of humidity and/or debris, is brought about by the transfer of angular momentum flowing from a motor towards the mirror.
The motor, located in the handle, rotates a shaft 54, which passes on the angular momentum as can be seen in Fig. 3. Motor 60 transfers angular momentum to shaft 54, further transferring angular momentum to bevel gear 62. The angular momentum is further transferred to another gear which may be a rotation rate increasing gear 64. Finally, the gear 66 at base of the mirror receives the angular momentum for providing the desired power to spin the mirror. However it should be pointed out that gears 64 and 66 are representative of several optional combinations of two to several more gears that can induce a desirable rotational velocity (spin) in the mirror. Structurally, a preferred angular momentum train is shown in Fig. 4. Shaft 54 has a conical gear 70 at its terminus which interacts with gear 72 (mostly hidden in this figure) having a common axis 76 with gear 74. Gear 74 interacts with gear 78. Gear 78 interacts also with gear 66 which is attached to the axis 80 of mirror 26. In Fig. 4A the bevel gear and surrounding components of the angular momentum train are shown in more detail. Shaft 54 revolves, transferring angular momentum to bevel gear 62, consisting of two conical gear wheels. Conical gear wheel 70 is engaged with conical gear wheel 72, while axis 76 transfers the angular momentum to gear 74.
Mirror maintenance
In such a case as the mirror is damaged or worn out, the part as shown in Fig. 2 can be pulled out of the handle and replaced, It should be noted at this point that sheath 56 may or may not be replaced, and is made to envelop shaft 54 without engaging with it in order to allow free spin within the sheath.
Mirror activation automation
As the mirror gets damp and or soiled upon use, the user is expected to activate the spinning mechanism by turning on the on/off switch 24 in order to clear the mirror. A schematic block diagram describing the AMAM is depicted in Fig. 5 An alternative switching mechanism is an automatic one. Such an automatic mirror activation mechanism (AMAM) is an electro-optical module which includes a lighting element 82 (typically a LED, light emitting diode) located preferably on handle 22. The emitted light is propagated from the light source element to the reflective face 26A of the mirror. A photo detector 84 located possibly in the vicinity of the LED, such as on handle 22 aims at the reflective mirror 26A. Ideally, a certain portion of the light energy emanating from the LED is received by photo-detector 84. Processor 86 calculates the ratio, and if the proportion of received power relative to the power of the beam is too low, the processor would switch the mirror driver 88 to start spinning the mirror automatically. In some embodiment, the light source of the AMAM such as lighting element 82 is an Infrared source, that is especially more sensitive to optical absorption by water relative to light in the visible wavelengths Audio switching
A form of sound or word recognition module can be inserted in the dental mirror assembly to pick up and recognize words or utterances issued by the practitioner in order to switch on or off the spinning mechanism. As the case is with known voice recognition mechanisms, the mechanism has to go through a training session. As can be seen in Fig. 6, microphone 92 functionally connects to processor 86, after the signal has been digitized and prepared for acceptance by the processor. Once the signal has been analyzed and interpretation achieved, a positive outcome will activate the motor driver 88. The practitioner may decide to evoke the system by an utterance or a specific sound so that instances of false alarms are minimized.
Such a module is typically harboured in the handle.
In Fig. 7, the optional switching mechanisms 94 are shown as they refer to mirror spinning. Switching mechanisms are either manual switching 92, light reflection switching 96, utterance recognition switching 98 These are all mutually exclusively activated, effecting spinning mechanism 100 to subsequently spin mirror 102.
