Publication number: 20080166685Abstract: 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.Type: ApplicationFiled: October 29, 2007Publication date: July 10, 2008Applicant: Discus Dental, LLCInventors: Kenneth Rosenblood, Haim Levy, Ben Atkin, Nancy N.

Hard-wired and wireless system with footswitch for operating a dental or medical treatment apparatus
Publication number: 20070166662Abstract: 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.Type: ApplicationFiled: January 17, 2006Publication date: July 19, 2007Inventors: Kevin Lint, Jeremy Kile, Kenneth R.

Publication number: 20070166661Abstract: 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.Type: ApplicationFiled: January 17, 2006Publication date: July 19, 2007Inventors: Tod Brenner, Kevin Lint

Patent number: 7012203Abstract: A foot operable controller for a surgical instrument having a main foot pedal assembly providing either proportional or linear control signals when moved laterally and in a vertical direction. Friction between an operator's foot and the foot pedal is minimized by a foot pad having a rotating heel plate. A neutral zone between left and right control positions of the foot pedal enables the operator to move his foot freely without changing control settings. Vertical displacement of the foot pedal is indicated by a plurality of mechanical detents during both upward and downward travel. Changing detent resistance alerts the operator to the vertical position of the foot pedal, indicating that further vertical displacement will change an instrument control signal corresponding to the new foot pedal position, thus providing sensory feedback to the operator indicating a change in the functional mode when the foot pedal is moved.Type: GrantFiled: September 7, 2001Date of Patent: March 14, 2006Assignee: Carl Zeiss Surgical GmbHInventors: Michael R. Hanson, Richard G. Thorlakson, B. J. Barwick, Jr.

Patent number: 6976843Abstract: An ultrasonic dental scaler automatically supplies a frequency to match a handpiece connecting thereto. A handpiece connector includes one or more passive elements, which affect the resonant frequency produced by the generator. Multiple handpieces, each operating at a different resonant frequency, may thus be used with the same ultrasonic generator. The ultrasonic dental scaler also supports two footswitches. One footswitch includes a foot-controlled power level adjuster. When connected, the footswitch automatically disables the manual power adjuster. Another on-off footswitch includes no power adjustment mechanism. When connected, the manual power adjustment feature of the generator is maintained. Orders for different handpiece frequencies and footswitch types can thus be filled with an inventory of one generator model.Type: GrantFiled: September 30, 2002Date of Patent: December 20, 2005Inventor: James Feine

Patent number: 6969254Abstract: A dental apparatus for hardening dental restoration components is provided that includes a control device controllable via a wireless communications unit and operable to exchange data with a communications unit. The control device is programmable to configure the control device to control a polymerization cycle and is connected with the communications unit with which the control unit exchanges data for changing the programming of the control device.Type: GrantFiled: September 12, 2002Date of Patent: November 29, 2005Assignee: Ivoclar Vivadent AG.Inventors: Wolfgang Plank, Thomas Stahl

Patent number: 6893261Abstract: The present invention relates to a footswitch which contains all operating elements of an ultrasonic dental scaling system. The footswitch incorporates the circuitry for controlling the frequency of the dental scaling tip and can also provide water and light which is fed to a remote head located either on the dentist or hygienist or on the dental chair adjacent the patient, thereby eliminating the need for a control unit on the counter top in the treatment room. The consolidation of the entirety of the control circuitry in the footswitch eliminates messy cable tangles and because it services a remote head located adjacent the patient allows the handpiece control cable to be shortened, thus lightening the strain on the technician and permitting easier and more efficient dental scaling to be accomplished.Type: GrantFiled: August 28, 2002Date of Patent: May 17, 2005Inventor: James Feine

Patent number: 6722881Abstract: A dental device having at least one pneumatically operable handpiece, the rotational speed of which can be influenced by a control element designed as a foot-operated switch, and a further handpiece, which can be driven by means of an electric drive, and the compressed air present at the pneumatic handpiece influences the control of the electric drive. A graduated filter is mounted on a pneumatically actuated hollow body and the graduated filter has regions thereon which can be sensed by a light barrier generating an electric signal in dependence on the properties of the regions.Type: GrantFiled: March 11, 2002Date of Patent: April 20, 2004Assignee: Sirona Dental Systems GmbHInventors: Hans-Walter Altendorf, Karl-Heinz Lehmann
