Wireless Control For Dental Equipment
The present invention relates to a wireless remote control for dental equipment
, such as dental scaler tools, dental drills, prophy angles, rotary instruments.
[0006] In an exemplary embodiment of the present invention, a wireless control such as a foot pedal is used to control the operation of an ultrasonic
dental tool comprising a base unit, a handpiece comprising a handle and an insert, and a wireless control switch such as a foot switch. The handpiece is coupled at one end (i.e., the proximal end) to an electrical energy source, a fluid source and/or gas, via a cable. The cable includes a hose to provide a fluid (e.g., water), and/or a gas, and conductors to provide electrical energy. The other end (i.e., the distal end) of the handpiece has an opening intended to receive an insert with a transducer (e.g., a magnetostrictive transducer) carried on the insert. The transducer extends from the proximal end of the insert into a hollow interior of the handpiece. An ultrasonically vibrated tip extends from a distal end of the insert. The handle has means therein which is adapted to impart a vibration to the insert. Such means are well known in the art and may be mechanical, magnetostrictive or piezoelectric in nature. The dental tool described can be in the form of a dental scaler.
[0007] When the wireless control is a foot switch, depressing the foot switch will result in activation of the ultrasonic handpiece and also delivery of cooling water to the insert tip. When the foot is removed from the foot control, both the ultrasonic handpiece and water are shut off.
[0008] The wireless control, such as the foot switch, replaces manual and foot operated controls formerly connected by cables to the dental tool and/or to the power supply. This removes a potential safety hazard in the dentist's office and makes the equipment control more versatile and easier to adapt to various office conditions.
[0009] In another exemplary embodiment of the invention, the dental tool comprises a base unit, a handpiece comprising a handle, a dental insert and a wireless control switch such as a foot switch. The dental tool is connected to a power, and/or fluid, and/or an air supply source through a conduit cable, so that the supply source, though coupled to the tool, is located at a position remote from the working end of the tool. The wireless foot switch, in the form of such as a pedal, is located within easy reach of the operator to permit turn-on and/or turn-off of the tool. The signaling means which simply and yet effectively provides for selective automatic turn on and turn off of the tool while totally eliminating the need for an electrical connection between the main supply unit and the remote control unit again removes a potential safety hazard in the dentist's office and makes the equipment control more versatile and easier to adapt to various office conditions. In addition to controlling the on and off of the dental tool, the wireless module can also be programmed to control the speed of the tool by a switch on the tool.
[0010] The dental tool includes a
dental drill, a
rotary instrument, an endodontic file and a
prophy angle. A common or different handpiece can be used with various inserts to form these tools. For example, a dental drill comprises a drill bit; a rotary tool comprises an insert, such as a multi-use diamond dental bur; a dental carbide bur; a dental sintered diamond bur; a dental diamond disc; a dental laboratory tungsten carbide cutter; a steel dental bur; an endodontic file; and a prophy angle comprising a longitudinal body and a prophy cup. The insert comprises a shank or attachment adapted to be fitted into the handpiece.
[0011] In addition to having wireless control in a dental office, a still further embodiment of the invention comprises a wireless control such as a foot switch for use with, especially rotary dental instruments or drills, in a dental laboratory. A dental drill or a rotary dental tool such as a carbide bur, is connected to a power supply through a conduit cable so that the power supply source, though again coupled to the handpiece, is located at a position remote from the working end of the handpiece. The wireless control in the form of such as a foot pedal is located within easy reach of the operator to permit turn-on and/or turn-off of the instrument, thus again eliminating the need for an electrical connection between the main power supply unit and the remote control unit. This removes a potential safety hazard in a dental laboratory and makes the equipment control more versatile and easier to adapt to various laboratory conditions.
[0012] In still a further aspect of the present invention, the above exemplary dental tools can also be fitted with at least one light source. The light source can draw its power supply from the same or different power source that supplies the power for the operations of the tool, or the light source can draw its power from the energy created by the ultrasonic vibrations. A wireless control means for the selective energizing of the light supply source can be separate or the same as the wireless means that controls the on and off of the dental tool. If a separate control is used, it can also be located within easy reach of the operator to permit turn-on and/or turn-off of the light supply source through simple foot pedal control provided within a remote control unit
[0013] These and other advantages and features of the invention will be more readily understood in relation to the following detailed description of the invention, which is provided in conjunction with the accompanying drawings.
