摘要： A dental handpiece is provided with a gripping sleeve, which receives a base member arrangement composed of either a single piece or multi-pieces. The base member having bearing arrangements for supporting a drive shaft section, which is engageable with the drive shaft of a motor and has an arrangement for guiding various agent lines, such as water, air or light or electrical power on the outer surface of the base member within the interior of the sleeve. The outer sleeve is free of holding and guide elements for the agent lines and the gripping sleeve can be firmly clamped onto the base member or can be clamped to the base member with interposed elastic vibration-dampening elements.

摘要： A dental handpiece, which has a drive motor part connected to a housing and a head part with a socket for supporting a tool for rotation being releasably secured on the housing, characterized by the handpiece being convertible between an angled handpiece and a straight handpiece. This is accomplished by the housing being composed of a first housing member, a second housing member, a device for interconnecting the first and second housing members for swivel movement between a first position with their drive shaft sections extending at an angle to each other and a second position with the drive shaft sections being in axial alignment, and a device for holding the housing members in a selected one of the first and second positions. The head part has a sleeve of a configuration to telescopically cover the second housing member and the majority of first housing member while the members are held in one of the first and second positions so that by changing the head part to provide another head part having a sleeve with a different configuration, the handpiece is converted between an angled handpiece and a straight handpiece.

摘要： A sleeve that has the shape seen in the longitudinal direction that deviates in cross section and/or has an outside diameter that changes from a shape with a rotational symmetry to a shape with a non-rotational symmetry and has a ridge extending at least a portion of the length of the sleeve to form ledges between the ridge and adjacent curved surfaces. A method for manufacturing the sleeve includes inserting a workpiece in a die having the desired contour for the outer surface of the sleeve, heating the material and subjecting the material to internal pressure to deform the workpiece into the contour of the die to form the sleeve.

摘要： A dental handpiece with at least two drive shaft sections for transmitting the rotary motion from a drive motor to an acceptance socket which is rotatably mounted in a head part of the handpiece, each of the drive shaft sections being arranged with their axes at an angle to one another and one of the two drive shaft sections having two coaxial gears which have different numbers of teeth and the other drive shaft section having at least one gear characterized by one of the two sections being mounted for axial displacement between two positions with one of the positions having one of the two gears in engagement with a gear and the other position having the other of the two gears in engagement with a gear. The gears on the drive shaft sections can be selected so that in one of the positions a direct drive can be obtained and in the other position either a step-up or step-down ratio can be obtained. In one embodiment, a single gear of the one section coacts with the two gears of the other section. In another embodiment, each of the drive shafts have two gears with the axial displacement between the two gears such that one pair of gears is in engagement when the displaceable shaft is in one position and a second pair of gears is in engagement when the section is in the second position.

摘要： An improved dental handpiece arrangement utilizes a drive cartridge containing the drive motor. The drive cartridge coacts with a coupling member and can be utilized with either a tubular adapter which enables use with one type of dental grip piece or can be utilized with a grip piece having an integral tubular portion for receiving the cartridge. The arrangement with the motor cartridge provides a great flexibility of utilizing grip pieces of different constructions.
