摘要:
In a dental, dental-medical or dental-technical handpiece, having an elongate grip sleeve there are provided at the rearward end of the grip sleeve coupling elements for the connection of the handpiece to a supply hose to be connected with a dental supply arrangement, and there are provided at the forward end of the grip sleeve a head section with a tool receiver for mounting a tool to be put into rotation. The handpiece further has an electric motor for driving a tool held by the tool receiver, which motor is completely integrated into the grip sleeve such that grip sleeve and motor form a unit.

摘要:
A motor-driven handpiece, which has a grip sleeve with a head area for mounting a tool, in particular for the preparation of tooth substance and/or bone substance, in which the head area is at least partially surrounded or encapsulated by a thermoplastic material which, compared to the material of the rest of the grip sleeve, has a lower thermal conduction value.

摘要:
A process and also to a system for cleaning and maintaining a medical hand-held instrument, in particular a dental hand-held instrument, with an elongate grip sleeve in which elements are arranged which pertain to a drive arrangement and which are, in particular, rotatably supported, for example a shaft. For the purpose of cleaning and maintaining the hand-held instrument different media are conducted through it. In this connection a first medium, for example oil, is conducted merely through a power-transmission region surrounding the elements of the drive arrangement, whereas, on the other hand, a second medium, for example a cleaning agent, is conducted additionally also through at least one further cavity within the hand-held instrument.

摘要:
The invention relates to a handpiece (3) for medical purposes, having a tool holder (5) arranged in the forward end region of the handpiece (3), a retaining coupling (16) for releasably fixing a tool (6) in the tool holder (5), and a drive connection (8), for a rotary and/or stroke drive of the tool holder (5), extending longitudinally through the handpiece (3), there being provided an arrangement for limiting the maximum torque value which can be transmitted to the tool holder (5) to a lesser torque value. For the purpose of broadening the range of application of the handpiece (3), the arrangement can be selectively deactivated and again activated, by means of a setting device (14).
摘要:
In the case of a handpiece (3) for medical purposes, preferably for a cutting treatment of a dental root canal, with a tool holder (5) arranged in the front end region of the handpiece (3), with a retaining coupling (16) for detachable fastening of the tool (6) in the tool holder (5) and with a drive connection (8) extending lengthwise through the handpiece (3) for a rotary and/or reciprocating drive of the tool holder (5), an overload coupling (14) that limits the transmittable torque to a maximum torque value is arranged in the drive connection (8).
