摘要:
An input device for the activation and control of functions of at least one apparatus of a dentist's or dental treatment station/work station, wherein the input device has a first input element for the generation of navigation information for the control of a pointer on a user interface, which is represented on a display of the dentist's treatment station, at least one second input element for the generation of control information with which functions of the apparatuses are selectable and/or activatable independently of the navigation information generated by means of the first input element, and transfer means for the wireless transfer of the navigation and control information generated with the aid of the first and second input elements to the apparatuses or to a functional unit connected upstream of the apparatuses. The input device is so configured that the control information generated via the second input element is usable independently of a unit, e.g. a central server, administering the user interface, for control of the apparatus.
摘要:
In a method for the production of a dental moulded part, in which there is produced a coquille (10) having a hollow space (11) the form of which corresponds in substance to the form of a model (2) of the moulded part, and in which by filling of the coquille hollow space (11) with a hardenable material a casting (20) is produced and hardened, the model (2) is provided with an offset (2a, 2b, 2c) which is taken into account in the production of the coquille (2), wherein after the hardening of the casting (20) this is worked by material removal to produce the dental moulded part.
摘要:
The invention relates to a medical or dental-medical handpiece having a rotary part which is rotatably mounted in a bearing bush by means of a roller bearing having an inner ring and an outer ring. In order to improve the handpiece with regard to an axial limiting of the roller bearing there is arranged in the inner surface of the bearing bush or in the outer surface of the outer ring a first ring groove in which there sits a securing ring which projects out of the first ring groove and bears at least with its one side on a shoulder surface of the respective radially oppositely lying part.
摘要:
In a dental device for the investigation of the optical properties of tooth tissue, in particular for the recognition of caries, plaque, bacterial infection, concretions and tartar, having a generator for generating an excitation radiation, which is to be directed onto a tooth tissue region to be investigated, a radiation detector and a radiation evaluator for the detection and evaluation of a response radiation arising from the irradiated tooth tissue region as response to the irradiation, and an indicator means for the indication of a measurement result determined by the evaluation means on the basis of the detected response radiation, the excitation radiation generator, the radiation detector and at least also the indicator being integrated in a dental handpiece.
摘要:
In the case of a medical or dental treatment instrument for the treatment of body tissue or a substitute material, in particular by cutting, with an elongated handpiece which in its front end region comprises a retaining device with a plug-in hole, into which the tool with its tool shank is capable of being inserted and is capable of being locked by means of a locking part which is movably supported transversely in relation to the tool shank between a locking position in which it is set into a locking recess in the tool shank and a release position releasing the tool shank and is pressurised into its locking position by the force of a spring, an actuating member which is manually accessible from outside is provided which is movably supported on the retaining device and with which the locking part is capable of being displaced into its release position, the actuating member being displaceably supported transversely in relation to the tool shank.
摘要:
In a tooth cleaning instrument (1) with an elongate handpiece, which carries a tooth cleaning tool (3) on its forward end, which can be set into vibration by a motor driven vibration generator (7) which is associated with the tooth cleaning instrument (1), whereby the tooth cleaning instrument (1) is connected or is detachably connectable at its rear end to a supply hose (6) having energy and/or media supply lines, the tooth contact element (17) is areal or quasi-areal and has a surface structure which is suitable for the abrasion of the tooth coating.
摘要:
In a handpiece head for a medical or dental handpiece having an in particular angular housing, in which a treatment tool is mounted so that it can move back and forth along it centre axis and rotate, wherein a rotating position adjustment device for the treatment tool is associated with the handpiece head, and has a positioning coupling with two interacting coupling parts,a rotating engagement member for the treatment tool that is manually externally accessible is movably mounted on or in the housing,the rotatable engagement member and/or the positioning coupling are/is connected to the treatment tool by a displacement coupling that enables stroke movement of the treatment tool, andthe positioning coupling is effective between the housing and the rotatable engagement member or the treatment tool.
摘要:
In a machining device for machining precision, in particular dental, workpieces in a machining chamber surrounded by a housing, having an inspection window with two gripping holes arranged to the two sides of the inspection window, the machining chamber is preferably connected or connectable to a suction device and arranged in the machining chamber is at least one blasting nozzle for blasting and/or a demolding tool for demolding and/or an air nozzle for blowing off the workpiece.
摘要:
In a medical or dental instrument having a driven treatment tool and an illumination device with a lamp, in particular for the treatment area, wherein the lamp is mounted in a plug-in socket, the plug-in socket is formed by two spring elements biassed towards one another between which the lamp is mounted to swing freely. Alternatively at least one damping element can be arranged between the holder and the lamp or the holder can be mounted elastically on the base part.
摘要:
A medical treatment device, in particular for surgical purposes, having at least one treatment instrument in the form of a hand piece which can be connected to a control unit by means of a flexible supply line, there being associated with the treatment device, preferably with the control unit, a source of treatment agent, in particular for cooling fluid, to which it is possible to connect a treatment agent line, which extends at least in part through the supply line to the front end of the hand piece, in the form of a hose, the treatment agent line having a hose section which extends with radial play for movement in the supply line as far as the hand piece and is there connected to a plug-in spigot which is plugged in a releasable manner in an axial plug-in socket in the hand piece and has an axial and a radial channel section, of which the axial channel section issues from the hose connection and the radial channel section is connected to the continuing treatment agent line.
