Abstract: A motor-driven dental device has a motor control that is responsive to a load placed upon the motor. More specifically, the invention relates to a dental device having motor that drives a tool, wherein the tool is activated or otherwise controlled in response to a load placed upon the motor through the tool, such as by touching the tool to a surface. The tool may also be controlled by the sustenance, over a predetermined time period, of an increase or decrease in motor current beyond a predetermined hysteresis current threshold. The motor may be an electric motor, a rotary electric motor, and air driven motor, an ultrasonic device or the like.

Abstract: A device includes a connecting end and a working end. Device has an internal fluid passageway and a bend area. The fluid passageway has a discharge opening or hole, which opening is positioned or located substantially away from the bend area, such that the discharge opening and upstream portions of the passageway will remain unaffected, substantially unaffected, or selectively affected by any deformation thereof due to the bending procedures employed to make the other portions of the tool, such as those conventionally involved in fabricating the bend area.

Abstract: A hard-wired and wireless system for operating a dental or medical treatment apparatus is provided. The system includes a footswitch device and a dental/medical base unit, each having a communication element for transmitting and receiving signals. The footswitch and base unit are each programmed to have an initial identification address Then, the footswitch and base unit are reprogrammed to know the identification address of the other. The footswitch and base unit can be reprogrammed in the field by the end user. Subsequent communications between the footswitch and base unit include both identification addresses. The footswitch includes two switches that are activated by depressing the upper cover of the footswitch to a first position and second position respectively. The footswitch is particularly suitable for operating an ultrasonic dental scaler.

Abstract: A foot switch device for activating a dental or medical treatment apparatus is provided. The foot switch device is particularly suitable for controlling an ultrasonic dental scaler. The foot switch device includes a base plate; a central housing attached to the base plate; an upper, moveable cover mounted on the housing; and a connecting collar attached to the upper cover for retaining the cover on the housing while allowing the cover to move upwardly and downwardly relative to the housing. The central housing contains a first electrical switch for transmitting a first signal to the apparatus, and a second electrical switch for transmitting a second signal to the apparatus. An operator depresses the upper cover with his or her foot to activate the switching mechanism and control the operation of the dental or medical apparatus.
