A device for disinfecting, sterilizing and/or maintaining medical, especially dental, instruments comprises a maintenance and cleaning chamber for accommodating instruments to be conditioned and means for supplying different cleaning or maintenance media for cleaning, disinfecting or sterilizing and/or maintaining the instruments in subsequent steps. The start times of the conditioning cycles for the different instruments are staggered.

Device for disinfecting, sterilizing and/or maintaining medical, especially dental, instruments

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.

Process and system for cleaning and maintaining and for operating a medical hand-held instrument

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.

Electric motor for use in a sterilizable dental handpiece

Dental, dental-medical or dental-technical handpiece with electric motor

In the case of a treatment device, in particular a dental treatment instrument, having a tool, such as a dental drill, driven by a drive unit, and a conduit for delivery of a cooling medium to a treatment site worked by the tool, the quantity of the cooling medium delivered to the treatment site is dependent upon the removal power of the tool or upon the torque exercised by the tool.

Dental handpiece

In a medicinal or dental hand instrument ( ) comprising a hand piece ( ) and a handle ( ) arranged on the hand piece ( ), an outlet opening ( ), arranged on the front side of the handle ( ), for the outlet of an abrasive therapeutic agent and a transport fluid, and a coupling terminal ( ) for coupling the hand instrument ( ) to a supply line for at least one transport fluid, in particular water and/or air, wherein the coupling terminal ( ) is a coupling component ( ) of a coupling ( ), the coupling component ( ) is arranged on an insert piece ( ) which can be plugged into a plug-in socket or plug-in recess ( ) and in its end zone, facing away from the flow, has one or more coaxially or paraxially disposed, sealed pipe socket couplings ( ), which each connect a feed line ( ) for the transport fluid to an ongoing feed line ( ).

Medicinal or dental hand instrument

The invention relates to a medical or dental-medical treatment instrument ( ) having a rod-like handpiece ( ) with the forward end region of which a tool ( ) can be releasably coupled by means of a tool coupling ( ), and the rearward end region of which can be releaseably coupled with a connection part ( ) by means of a handpiece coupling ( ), preferably a plug-in/turn coupling, the handpiece having: a grip sleeve ( ) which forms an outer body of the handpiece ( ), an oscillatory rod ( ) which extends longitudinally in the grip sleeve ( ) and is mounted therein radially or also axially elastically yieldingly, an in particular pneumatic oscillation generator ( ) for transmitting oscillations to the oscillatory rod ( ), and a sleeve ( ) surrounding the oscillation generator ( ). For reducing noise emissions, the sleeve ( ) is of elastically compressible or sound-absorbing material.

Medical and/or dental instrument with a pneumatic oscillatory-drive

The invention relates to a handpiece ( ) for medical purposes, having a tool holder ( ) arranged in the forward end region of the handpiece ( ), a retaining coupling ( ) for releasably fixing a tool ( ) in the tool holder ( ), and a drive connection ( ), for a rotary and/or stroke drive of the tool holder ( ), extending longitudinally through the handpiece ( ), there being provided an arrangement for limiting the maximum torque value which can be transmitted to the tool holder ( ) to a lesser torque value. For the purpose of broadening the range of application of the handpiece ( ), the arrangement can be selectively deactivated and again activated, by means of a setting device ( ).

Medical and dental handpiece

In a medical or dental treatment instrument (,) for chip-removing treatment of body tissue or a substitute material with an abrasive tool (,), consisting of a handpiece (,) with an oblong gripping sleeve (,), in the front end area of which a vibration part (,) is supported, which can be set vibrating by a vibration generator (,), the handpiece (,) being connected or connectable at its rear end area to a flexible supply line (,), which extends from a supply device, the output of the vibration generator (,) is variable, and a control device (,) is provided with which the output can be increased or reduced.

Medical or dental treatment instrument for chip-removing treatment of body tissue or a substitute material with an abrasive tool

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).

Handpiece for medical purposes, in particular for a medical or dental

A handpiece having a releasable retaining device for a tool having a shaft about which the tool rotates. The handpiece has a housing and a drive sleeve rotatably mounted in the housing. The drive sleeve has a hollow cylindrical insertion hole into which the shaft of the tool is placed. A drive means is provided for rotation of the drive sleeve. First and/or second releasable couplings are provided for rotatably and/or axially connecting the shaft to the drive sleeve. The releasable couplings have either a coupling slider or pressure member which is displaceable between coupling and decoupling positions. An actuating device is provided for displacing the coupling slider or pressure member into their decoupling position. In one embodiment the coupling slider is made of a ceramic material and fabricated into its final form by means of a single fabrication process without after treatment. In another embodiment the coupling slider is made from a ceramic material, and a ring-shaped spring (urging the coupling slider into its coupling position) has ends separated by a distance. The coupling slider has two peripheral grooves on a side opposite a free end of the coupling slider, in which grooves the ends of the ring-shaped spring are disposed. In a third embodiment, the pressure member is fabricated from a ceramic material and has a color mark on a visible surface formed by coloring the ceramic material.
