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： A dental handpiece provided with a handle having one end connected to a supply hose with several supply lines for liquid or gaseous media. A head section with a dental tool is connected to another end of the handle, and the handle is provided with hollow conductors for carrying the media from the supply lines to the head section. The handle may be rotated about the longitudinal axis of the handle, and relative to the supply hose. The means for rotating the handle is located inside the handle, and the latter is further divided into two portions which are turnable with respect to each other. One of the portions is adjacent to the supply hose, and is non-rotatable with respect to the supply hose. The other portion is connected to the head section and has a length which is at least one-third and at most two-thirds of the overall length of the handle. The part of the handle which is connected to the head section, is in the form of a sleeve-shaped end element which is inserted into a suitably formed mating piece in the other handle portion. The sleeve-shaped element is supported by bearing elements against the respective handle portion.
