A removable toothbrush head for an electric toothbrush includes a bristle carrier and an elongated neck. One end portion of the elongated neck includes an opening for connection to an electric toothbrush handle, and another end portion comprises a neck hub configured to rotatably support the bristle carrier. Also included is a driven brush shaft disposed longitudinally within the elongated neck. The brush shaft is configured to interact with the bristle carrier at a distal end portion of the brush shaft, which includes a pivot extension extending therefrom and spaced apart from the longitudinal axis of the brush shaft, as well as a bristle carrier interface positioned at least partially along the longitudinal axis of the brush shaft and configured to cause partial rotational motion of the bristle carrier when the brush shaft is driven by an electric toothbrush handle.

An oral care device attachment for being coupled to a drive shaft of an oral care device handle, the attachment including: an outer attachment tube having a coupling end that is intended for being secured at the oral care device handle; a carrier mounted for driven motion at the outer attachment tube; a motion transmitter disposed inside of the outer attachment tube; where a spring is arranged that the motion transmitter is biased into a position towards the coupling end of the outer attachment tube.

A toothbrush has a handle and a treatment head mounted for movement relative to the handle against a spring force when a treatment force is applied in at least one treatment direction onto the treatment head. A treatment force measurement unit for determining the applied treatment force includes a capacitive force senor having a first electrode fixedly mounted with respect to the handle and a second electrode mounted at a distance from the first electrode. The second electrode is movably mounted with respect to the handle. A spring unit is arranged between the first and the second electrode. A control circuit determines at least one parameter indicative of the capacitance between the first and second electrodes, wherein the second electrode is mechanically coupled with the treatment head and is arranged to be moved relative to the first electrode when the treatment force is applied at the treatment head.

Oral care implement that can be detachably coupled to a handle having a motor. The oral care implement includes a drive assembly to operably engage the motor, a head portion that includes a body, a first carrier comprising a plurality of bristle tufts extending from the first carrier, the first carrier comprising a central passageway; and a second carrier disposed within the central passageway of the first carrier, the second carrier comprising an elastomeric cleaning element extending from the second carrier. The drive assembly may be operably coupled to each of the first and second carriers and configured to: (1) produce a first oscillatory motion of the first carrier about a first rotational axis; and (2) produce a second oscillatory motion of the second carrier, the second oscillatory motion being counter to the first oscillatory motion.

Described herein is an oral care implement that includes a head portion; a cup member extending from a front surface of the head portion along a first axis, the elastomeric cup member comprising: a top surface; a plurality of grooves formed into the top surface; a plurality of rib members, wherein adjacent ones of the grooves are separated by one of the rib members, each of the rib members extending along a rib axis that extends radially outward from the first axis, and wherein each of the rib members has a thickness that increases with distance from the first axis. The cup member may comprise a plurality of first grooves and a plurality of second grooves, and wherein each of the first grooves has a first transverse cross-section and each of the second grooves has a second transverse cross-section, the first and second transverse cross-sections being different from one another.

The present disclosure generally relates to a brush head for an oral hygiene device. More specifically, the present disclosure relates to a brush head with magnetic attachment mechanisms for repeatedly attaching and detaching a connector to a cleaning element of the brush head and magnetic attachment mechanisms for repeatedly attaching and detaching the connector to a handle of the oral hygiene device.

The invention relates to a toothbrush having a handle and a head part, on which bristle filaments and at least one flexible cleaning element are arranged. According to the invention, the at least one flexible cleaning element is arranged on a carrier element which consists of a hard material and is connected to the head part. The invention also relates to a process for producing such a toothbrush.

An oral cleaning tool for an electric oral hygiene device is disclosed. The oral cleaning tool includes a housing having a head section with a head cavity for accommodating a movable oral cleaning head and a neck section with a neck cavity and a handle coupling section; a first magnetic coupling element including at least a permanent magnet or a magnetizable element being provided in the neck section for mechanical handle drive shaft connection by magnetic interaction. The first magnetic coupling element is mounted at a motion transmitter, the motion transmitter extending inside the neck cavity to the head cavity, the motion transmitter arranged so as to be movable in a linear or longitudinal direction. The motion transmitter is coupled with the oral cleaning head, the oral cleaning head arranged so as to oscillate in a rotational direction.

The object of the invention is a brush head for an electric toothbrush, the brush head comprising a hollow body part (1), a back and forth rotating shaft (3) inside the body part (1), and a rotating bristle carrier (7) rotated back and forth by the shaft (3) at the first end of the body part (1), and where the second end of the shaft (3) comprises a protrusion (3a) that is in an inclined angle (A) in relation to the rotation axis of the shaft (3). The inclination angle (A) is substantially between 20-70 degrees, and the inclination of the protrusion (3a) is directed towards the rotation axis of the shaft (3).

A plantar plate augmentation kit assembly with a plantar plate joint distractor with two members operably configured to move with respect to one another to have an open position configured to separate tissue and a closed position along a spreader opening path, a graft material, two wires configured to attach to the graft material, a graft passer having a handle portion and a portion of the graft passer configured to facilitate in the handling of the graft material, at least two interference screws with screw threads for securing the two wires and graft material into place, and a drill bit for repairing plantar plate tears through graft augmentation.
