Dental Equipment

The present invention relates to a wireless remote control for dental equipment

, such as dental scaler tools, dental drills, prophy angles and other rotary instruments. The wireless control switch can control the on and off state of the dental tool, or it can also be programmed to control the speed of the tool by a switch on the tool. The wireless control switch can be in the form of, for example, a foot switch, and replaces manual and foot operated controls formerly connected by cables to the dental tools. 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. The wireless control can be battery powered, further eliminating the need for cables.

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.

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.

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.
