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.

A magnetostrictive ultrasonic dental scaler is disclosed. The magnetostrictive device comprises an oscillator adapted to provide electrical energy including a current and a voltage signal, a handpiece having a tool tip which vibrates in response to the electrical energy supplied to the handpiece and a control circuit. The control circuit includes a phase detector adapted to detect phase between current and voltage signals and to generate a phase detection signal as a function of the phase. The control circuit also includes a digital signal processor operatively connected to the phase detector. The digital signal processor adapted to process the phase detection signal through a digital loop filter to generate an error signal. The control circuit further includes a voltage controlled oscillator operatively connected to the digital signal processor, wherein the error signal outputs a voltage to operate the voltage controlled oscillator which in response thereto adjusts at least one of frequency and amplitude of vibrations of the tool tip.

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.

A dental hygiene accessory for cleaning a dental scaler or similar dental instrument has a platform member with a multitude of bristles upstanding from a central area of the platform. An annular body of soft dental debris retaining material is carried by the platform and surrounds the bristles. The accessory also has a retainer extending downwardly from the platform and engageable with a hygienist's finger to retain the accessory thereon.

A dental scaler for cleaning teeth having an orthodontic appliance. The scaler includes a handle with at least one scaling portion having a scaling element. The scaling portion of the device consists of a plurality of sections connected by a plurality of angles and is designed to permit the scaling element to fit between a brace wire and a tooth.

The invention relates to a method for manufacturing a dental scaler tip using a powder injection molding process, a mould, and a scaler tip that is excellent in shape-reliability and injects fluid to a front end thereof along a curved section of the tip. The method comprises the steps of preparing feedstock and injecting the feed stock into a mould to form a molding body, wherein, the mould comprises an operating section to which cylindrical core pins having multi steps and an eccentric end formed at a front end thereof for forming the fluid passage is mounted; and a pair of slide cores disposed for supporting the eccentric ends of the core pins such that the slide cores face each other and are slid in the direction perpendicular to the movement direction of the core pins to form a cavity corresponding to a shape of an article to be formed.

The present invention relates to a dental scaling translucent insert which provides a coaxially aligned light adjacent the distal end of such insert for illuminating the tip of the dental scaler which light may be provided by light emitting from a fiber optic light guide from a light source located remotely from the tip. The light provided can also be used to view through a camera lens system located in translucent insert to provide a clear unobstructed view of the work at the tip of the scaler on a remote screen or for recording.

A method in which a digital picture of the tip of a dental scaler tool and other uniquely identifying characteristics is used to measure the extent of wear on the tool. Unique characteristics of the dental scaler tool, such as color and shape of the grip, narrow a set of reference images to a subset of likely matching tip reference images. A digital contour of the worn tip is isolated. Characteristics of the physical shape of each available tips have been stored in a digital library of reference images. The same tip shape characteristics are developed for the tip contour that were stored for each reference image. The digital profile of the worn tip and a matching, selected reference image of the tip from a library of digitally overlaid. An accurate measurement of the extent of wear of the insert tip is made and displayed.

The invention relates to an ultrasonic dental scaler for a brush bulged after being inflated. The ultrasonic dental scaler comprises a U-shaped tooth cleaning head with an upper tooth slot and a lowertooth slot, a main machine, and a micro ultrasonic transducer, wherein a brush is arranged in the tooth slots; a U-shaped inner chamber is further arranged in the U-shaped tooth cleaning head; at least one micro ultrasonic transducer is further arranged in the U-shaped inner chamber; the outer side surface of the U-shaped tooth cleaning head is further connected with an electric wire; the electric wire is electrically connected with the micro ultrasonic transducer; a pipeline is further connected on the outer side surface of the U-shaped tooth cleaning head; the pipeline is communicated withthe U-shaped inner chamber; and the main machine comprises a PLC circuit board, a micro air pump, a control button module and the like. A way of bulging the brush by inflating is adopted, and ultrasonic waves are utilized for performing high-frequency vibration on the bulged brush, so that inner and outer surfaces of teeth and tooth gaps of inner and outer surfaces are comprehensively and synchronously cleaned without a dead corner in an all-around mode through the brush in the tooth slots, and therefore, the problem that the teeth are damaged as a result of excessive cleaning is avoided, andthe problem of the cleaning is incomplete and is not thoroughly is avoided.

A dental insert (10) has a nozzle (30) supporting a grip sleeve (80). Nozzle 30 may include several components (31, 32, 33) that are assembled without the need for a weld. A grip retaining ring 60 is positioned at a nodal location.

The invention relates to the technical field of oral care, in particular to a multifunctional dental scaler. The scaler comprises a shell, a brush neck and a brush head; the brush neck is arranged at the upper end of the shell, mounting parts are arranged at the upper end and the lower end of the rear side of the shell in a protruding mode, a water tank is detachably connected between the mounting parts, and the brush head is driven by a first linkage assembly and rotationally mounted on the front side of the upper end of the brush neck. The brush neck is provided with a nozzle at the lower end of the brush head, the water tank provides water flow for the nozzle through a piston assembly, and the piston assembly is rotatably mounted in the shell through a second linkage assembly. Compared with a common dental scaler, the integrated multifunctional dental scaler integrates the two working procedures of tooth surface cleaning and tooth slit flushing, so the integrated multifunctional dental scaler is formed, the tooth flushing effect is achieved while a user brushes teeth, the tooth cleaning time is greatly shortened, the tooth cleaning efficiency is improved, and welfare is brought to people wearing the dental scaler with hidden beauty.
