[0003] [Patent Document 1] US Patent Application Publication No. 2003 / 0165794 Summary of the Invention [Problem to be solved by the invention]

[0004] The object of the present invention is to improve the design of a medical or dental equipment piece with regard to a hardwired power supply and communication link / data transmission between a storage device and a control, regulating or supply unit. In particular, it is desirable for the design of the equipment piece to be simple, and for the components forming the power supply and communication link between the storage device and the control, regulating or supply unit to take up little space, while ensuring a reliable power supply and data transmission. [Means for solving the problem]

[0005] These problems are solved by a method for operating a medical or dental equipment part or a medical or dental treatment device by a medical or dental equipment part as described below, which comprises a coupling device for connecting the equipment part to a control, regulating or supply unit, a memory element operable with power for storing identification data and / or operation data and / or care data of the equipment part, and at least one electric line provided for supplying power to a lighting device provided on or connected or connectable to the equipment part to operate the lighting device and for supplying power to the memory device to operate the memory device.

[0006] The design of the equipment part is significantly simplified by the provision of at least one electrical line for supplying power to the lighting device and for operating the lighting device and for supplying power to the storage device and for operating the storage device, which allows, for example, a reduction in the number of electrical lines in the equipment part. In particular, the design of a coupling device for connecting the equipment part to a control, regulating or supply unit is significantly simplified due to the reduced number of electrical contacts on the interface of the coupling device.

[0007] At least one electric line provided for supplying power to the lighting devices provided on or connectable to the equipment parts for operating the lighting devices and for supplying power to the storage devices for operating the storage devices is preferably designed as a joint or common electric line, in particular a joint electric line for the lighting devices and the storage devices. Thus, the lighting devices and the storage devices are in particular electrically connected to the (joint) electric line. In particular, a branch point is provided from which a first electric branch line extends to the storage devices and a second electric branch line extends to the lighting devices.

[0008] At least one (common) electrical line is preferably designed as a wireline and / or as an electrical line printed on a circuit board.

[0009] The term "medical or dental equipment part" is understood in the following to mean a medical or dental element that can be held in one hand, a handgrip element, a straight handpiece, an angled or bent or contra-angle handpiece, an adapter, a coupling element, a drive element, in particular an air or electric motor, or a supply tube, or part of the listed elements.

[0010] The equipment part preferably comprises a medical or dental handpiece or part thereof, i.e. a drive element detachably connectable to the handpiece and rotatable for driving the instrument, a coupling device for connecting the handpiece to a control, regulating or supply unit, a memory device operable with power for storing identification data and / or operation data and / or care data of the handpiece, a lighting device operable with power for emitting radiation waves at the treatment site, and at least one (common) electric line provided for supplying power to the lighting device for operating the lighting device and for supplying power to the memory device for operating the memory device.

[0013] The at least one electrical contact is preferably removably connected to the control, regulating or supply unit, and is, for example, preferably designed as a pin contact, as a spring contact, as a sliding contact or as an annular electrical contact surrounding the component of the coupling device.

[0014] The storage device comprises either a read-only memory (ROM) or preferably a readable and writable memory, and is particularly designed as a digital storage device for storing and / or retrieving and / or processing digital data.

[0015] In particular, the identification data and / or operation data and / or care data assigned to an equipment part with an integrated storage device are preferably stored or can be stored in the storage device of that equipment part. Alternatively, it is also conceivable that the identification data and / or operation data and / or care data of other equipment parts than the equipment part with an integrated storage device are additionally or exclusively stored in that storage device.

[0016] The storage device preferably comprises a storage element and a microcontroller or microcomputer, optionally designed as one component or as two separate components electrically connected to each other. If the storage element and the microcontroller are embodied separately from each other, they can be arranged in different positions in / on the equipment part, which makes it easier to arrange the two components in an equipment part with a small internal volume.

[0017] The storage device with a microcontroller is preferably designed to actively output digital signals or digital data and includes software that allows, among other things, receiving, transmitting, processing, storing data and / or performing independent control steps.

[0018] The supply of power to the lighting device and the storage device via at least one (common) electrical line, and preferably (digital) data transmission, can be performed, for example, by modulation and / or digital multiplexing and / or by time-offset transmission or transmission of digital data and / or power, in particular with the aid of a microcontroller in the storage device.

[0023] According to an alternative embodiment, at least one additional line is provided for transmitting identification data and / or operation data and / or care data between the storage device and a control, regulating or supply unit connectable to the device part. This additional line (hereinafter also referred to as a data line) is therefore preferably provided solely for data transmission between the storage device and the control, regulating or supply unit, and not for powering the lighting device and the storage device. This additional line can be designed, for example, as an electrical line for transmitting electrical (data) signals, or as an optical line, e.g., glass fiber, for transmitting optical (data) signals. The data line particularly preferably forms a direct connection between the microcontroller of the storage device in the device part and the control, regulating or supply unit, in particular another microcontroller arranged in the control, regulating or supply unit.

DETAILED DESCRIPTION OF THE INVENTION

[0096] 1 shows a medical or dental treatment device 11 comprising a medical or dental equipment part 1, a drive unit 14, a control, regulating or supply unit 4 and a supply tube 15 connecting the equipment part 1 to the control, regulating or supply unit 4. The equipment part 1 is detachably connected to the control, regulating or supply unit 4 by means of a coupling device 3.

[0097] The instrument part 1, shown enlarged in Fig. 2, is formed by a bent handpiece or a contra-angle handpiece. The handpiece 17 comprises a handpiece head 17A in which an instrument holder is arranged, in particular for removably fixing an instrument, and a handle part 17B for holding the handpiece 17 with one hand. The coupling device 3 and / or at least part of it is arranged at the free or proximal end of the handle part 17B.

[0098] The drive unit 14 may comprise, for example, an electric motor or an air motor, which may be designed as a separate component removable from the handpiece 17 (as shown in FIG. 1) or may be integrated into the handpiece 17. However, the drive unit 14 may also be located in the handpiece 17, particularly in the handpiece head 17A, and may comprise a propellant-gas-driven impeller. Thus, the handpiece 17 may be designed to be motor-operated and have at least one drive shaft for transmitting drive motion to an instrument, or to be operated by a propellant-gas-driven impeller. In either case, the handpiece 17 comprises at least one rotatable drive element for driving an instrument connectable to the handpiece.

[0099] Handpiece 17 preferably further includes an illumination device 2 disposed at or adjacent to handpiece head 17A. Illumination device 2, shown in Figure 2, specifically includes a plurality of light emitting diodes (LEDs) arranged in an annular pattern around instrument receptacle opening 16 of handpiece head 17A.

[0100] Furthermore, openings for discharging a medium such as water and / or air are preferably arranged alternately with the optical semiconductor elements around the instrument receptacle opening 16. The openings for discharging a medium are connected by at least one medium line in the handpiece 17 to a control, regulating or supply unit 4 for supplying at least one medium.

[0101] Furthermore, an electrically powered memory device is arranged in the instrument part 1 or the handpiece 17, storing identification data and / or operation data and / or care data for the instrument part 1 or the handpiece 17. The memory device 5 can be arranged in the handpiece head 17A or in the handle part 17B, or part of the memory device 5 may be arranged in the handpiece head 17A and another part of the memory device 5 in the handle part 17B. The memory device 5 or part of it may be arranged in the handle part 17B, for example at the proximal or free end of the handle part 17B, in particular in or on the coupling device 3, i.e. in the section of the handle part 17B that is directly connected to the bent part 18 of the handpiece head 17A or the handle part 17B.

[0102] The storage device 5 comprises a storage element 5A and a microcontroller 5B for operating, inter alia, the storage element 5A (see Figures 3 and 4).

[0103] As can be seen in Figures 3 and 4, the equipment part 1 or handpiece 17 further comprises at least one (common) electric line 6A, 6B for supplying power to the lighting device 2 provided on the handpiece 17 for operating the lighting device 2 and for supplying power to the storage device 5 for operating the storage device 5. The at least one (common) electric line 6A, 6B connects the lighting device 2 and the storage device 5 to a power source 12, in particular a constant current source, which is arranged in the control, regulating or supply unit 4 and is designed to supply power to the lighting device 2 and the storage device 5. As can be seen in Figures 3 and 4, the at least one (common) electric line 6A, 6B extends through a supply pipe 15 to or within the control, regulating or supply unit 4.

[0104] Thus, at least one (common) electrical line 6A, 6B electrically connects the lighting device 2 and the memory device 5 to the control, regulating or supply unit 4, in particular its power supply 12 and microcontroller 19, thereby forming an electrical switching, control, regulating or supply circuit. As will be explained in more detail below, the switching, control, regulating or supply circuit preferably comprises at least one sensor 10.

[0105] The power supply 12 in the form of a constant current source supplies the equipment part 1 or the handpiece 17 with power at a constant electrical amperage. This is the optimal power supply for a lighting device 2 including at least one optical semiconductor. However, the memory device 5, in particular the microcontroller 5B, requires a constant voltage power supply. Therefore, a device for processing voltages 8 is provided, which voltage processing device 8 is assigned to the memory device 5, in particular the microcontroller 5B, and is designed to convert the constant electrical amperage power received from the power supply 12 (via the electrical lines 6A, 6B) into constant voltage power and to supply the converted power to the memory device 5. The voltage processing device 8 is arranged in particular in the equipment part 1 or in the handle part 17.

[0106] According to Fig. 3, as mentioned above, two (shared) electric lines 6A, 6B are provided for supplying power to the lighting device 2 and the memory device 5. Furthermore, two electric lines 6A, 6B are provided for transmitting identification data and / or operation data and / or care data between the memory device 5 and the control, regulating or supply unit 4 connectable to the equipment part 1 or the handpiece 17. In other words, no more than two (shared) electric lines 6A, 6B are provided for supplying power to the lighting device 2 and the memory device 5 and for data transmission. In this way, the control, regulating or supply unit 4 is designed to exchange identification data and / or operation data and / or care data of the equipment part 1 with the memory device 5.

[0107] An electrical switching element 13 assigned to the memory device 5 is provided for transmitting the identification data and / or operating data and / or care data from the memory device 5 to the control, regulating or supply unit 4, i.e. for reading out the data from the memory device 5. As mentioned above, the switching element 13 is designed to cause or trigger a change in a current parameter, in particular the voltage or the electrical load, in particular by short-circuiting the shunt resistor 7. The change in the current parameter determines (digitally) the transmitted data. The control, regulating or supply unit 4, in particular its microcontroller 19, is designed to detect or equalize the change in the current parameter and, based on this, to detect or read out the (digitally) transmitted identification data and / or operating data and / or care data.

[0108] Furthermore, a shunt resistor 7 is provided in the instrument part 1 or handpiece 17, designed to handle changes in electrical amperage for transmitting identification data and / or operational data and / or care data between the memory device 5 and a control, regulating or supply unit 4 connectable to the instrument part 1. As mentioned above, the shunt resistor 7 is provided for storing data in the memory device 5, and in particular for transmitting data from the control, regulating or supply unit 4 to the memory device 5.

[0109] The control, regulating or supply unit 4, in particular its microcontroller 19, is assigned a further shunt resistor 20.

[0110] 4, as mentioned above, two (shared) electric lines 6A, 6B are provided for supplying power to the lighting device 2 and the memory device 5. Another line 6C is provided for transmitting identification data and / or operating data and / or care data between the memory device 5 and the control, regulating or supply unit 4 connectable to the equipment part 1 or the handpiece 17. In other words, three lines are provided for supplying power to the lighting device 2 and the memory device 5 as well as for data transmission: two (shared) electric lines 6A, 6B for supplying power and the above-mentioned further line 6C for transmitting data.

[0111] The further line 6C may be configured as an electrical line for transmitting electrical (data) signals or as an optical line, e.g., glass fiber, for transmitting optical (data) signals. The further line 6C extends through the instrument part 1 or handpiece 17 and the supply tube 15 to or within the control, regulating or supply unit 4.

[0112] Electrical contacts 3A, 3B connected to at least one common electrical line 6A, 6B are provided on the coupling device 3 of the instrument part 1 or handpiece 17, in particular on the end face of the coupling device 3 (see FIG. 2). These removable electrical contacts 3A, 3B electrically connect the lighting device 2 and the memory device 5 to the control, regulating or supply unit 4, in particular to its power supply 12 and microcontroller 19. As mentioned above, if only two common electrical lines 6A, 6B are provided for transmitting power and data, then only these two electrical contacts 3A, 3B are correspondingly provided on the coupling device 3. If at least one further optical or electrical line 6C is provided for transmitting identification data and / or operation data and / or care data, then optical or electrical contacts 3C are correspondingly provided, connected to the at least one further line 6C for transmitting data.

[0113] The at least one electrical contact is preferably removably connected to the control, regulating or supply unit 4. The at least one electrical contact is designed, for example, as a pin contact, as a spring contact, as a sliding contact or as an annular electrical contact surrounding a component of the coupling device.

[0114] Preferably, at least one sensor 10 is provided in the medical or dental equipment part 1 or handpiece 17, which sensor 10 is designed to detect the operating state of the equipment part 1 or handpiece 17 and to generate a sensor signal. The sensor 10 comprises, for example, a temperature sensor or a speed sensor for measuring the rotational speed of the equipment part 1 / handpiece 17. Figures 5A to 5C show different arrangements of the sensor 10.

[0115] At least one sensor 10 is electrically connected to at least one electrical line 6A, 6B, such that the sensor signal of the sensor 10 and / or power for operating the sensor can be transmitted via the at least one electrical line 6A, 6B.

[0116] At least one sensor 10 is also preferably electrically connected to the storage device 5, in particular the microcontroller 5B, so that the sensor signal of the sensor 10 can be transferred in particular to the storage device 5. The storage device 5, in particular the microcontroller 5B, is optionally designed to (1) transfer the (analog) sensor signal of the sensor 10, preferably to the control, regulating or supply unit 4, in particular its microcontroller 19, or (2) convert the analog sensor signal into a digital signal and transmit it to the control, regulating or supply unit 4, in particular its microcontroller 19, or (3) receive and process the (analog) sensor signal of the sensor 10 and activate, regulate or control the instrument part 1 / handpiece 17 or its components based on the sensor signal. Preferably, the sensor signal is transferred to the control, regulating or supply unit 4 according to (1) or (2) via at least one of the lines 6A, 6B, 6C.

[0117] In the embodiment shown in Figure 5A, the sensor 10, preferably a sensor for measuring rotational speed, is arranged electrically in series with the lighting device 2. In the embodiment shown in Figure 5B, the sensor 10, preferably a sensor for measuring temperature, is arranged electrically in parallel with the lighting device 2. In both embodiments, the sensor 10 and the lighting device 2 have a common power supply 12 and are electrically connected to the electrical lines 6A, 6B.

[0118] In the embodiment of FIG. 5C, the sensor 10, preferably a sensor for measuring temperature, and the lighting device 2 are connected to different power sources for receiving power.

[0119] The present invention is not limited to the embodiments shown and described herein. Moreover, the features of all the embodiments shown and described herein can be combined with each other.

[0120] Reference is now made to Figures 6-8, which illustrate different embodiments of a medical or dental treatment device 11. Elements illustrated in Figures 3 and 4 are also illustrated in Figures 6-8 and bear the same reference numerals: medical or dental equipment portion 1, radiation-emitting or illuminating device 2, control, regulating or supply unit 4, medical or dental equipment portion controller or microcontroller 5B, three electrical lines 6A, 6B, 6C, common power supply 12, supply tube 15 connecting equipment portion 1 to control, regulating or supply unit 4 and carrying electrical lines 6A, 6B, 6C, and microcontroller 19 of control, regulating or supply unit 4. The features, functions or characteristics described above in relation to these elements may also apply to the elements shown in Figures 6-8.

[0121] The medical or dental equipment part 1 may suitably be one of a medical or dental handpiece 17, a medical or dental drive element or electric motor 14, a medical or dental adapter, a medical or dental attachment or a medical or dental coupling device, in particular forming part of a supply tube 15.

Alternatively, the at least one sensor 10 can be connectable to and detachable from the medical or dental equipment piece 1, for example if it is included in an element that can be coupled to the medical or dental equipment piece 1. The at least one sensor 10 can be any of the sensors described above.

[0123] The three electric lines 6A, 6B, 6C shown in Figures 6 to 8 include a first common electric line 6A and a second common electric line 6B, which are connected to the medical or dental equipment partial controller 5B and the electromagnetic wave emitting device 2 and are configured to supply power from a common power source 12 to the electromagnetic wave emitting device 2 and the medical or dental equipment partial controller 5B, thereby operating the device 2 and the controller 5B. When at least one sensor 10 requires power supply for operation, power is also supplied from the power source 12 via the common electric lines 6A, 6B. Furthermore, one of the electric lines 6A, 6B, according to Figures 6 to 8, the electric line 6B, functions as a ground line.

[0124] A third of the three electric lines 6C connects the medical or dental equipment part controller 5B to the control, regulating or supply unit 4, in particular the microcontroller 19. The medical or dental equipment part controller 5B can have a memory element 5A (see Figures 3 and 4) which can store at least one of identification data, operation data or care data and / or at least one of the respective data of other equipment parts which are coupled or can be coupled to the medical or dental equipment part 1. The third electric line 6C is configured for data transfer, in particular the above-mentioned identification data, operation data or care data, between the medical or dental equipment part controller 5B and the control, regulating or supply unit 4, in particular the controller 19.

[0125] The third electrical line 6C further connects the at least one sensor 10 to the control, regulating or supply unit 4, in particular the microcontroller 19, so that a sensor signal of the at least one sensor 10 or data based on the sensor signal can be transmitted via the third electrical line to the control, regulating or supply unit 4. As can be seen clearly in Figures 6 to 8, the sensor signal is transmitted from the at least one sensor 10 via the data or signal line 6D to the medical or dental equipment part controller 5B and from there to the control, regulating or supply unit 4. As mentioned above, the equipment part controller 5B can be configured to transmit only the sensor signal or to store and / or process the sensor signal before transmitting it to the control, regulating or supply unit 4.

[0126] The electrical lines 6A, 6B, 6C, preferably the line 6D and / or the additional electrical lines are part of a bus system of the medical or dental treatment device 11, in particular a CAN, FlexRay, Lin, SPI or I 2 It may be part of a C-bus system.

[0127] The common power supply 12 is arranged in and / or forms part of the control, regulating or supply unit 4. Preferably, the common power supply 12 comprises or is formed by a constant voltage source. The power supply 12 therefore supplies constant voltage or DC power to the medical or dental equipment parts 1, in particular the electromagnetic wave emitting device 2, the medical or dental equipment part controller 5B and optionally at least one sensor 10.

[0128] 6 to 8 also show a first device 21 for processing power. The power processing first device 21 may include a power converter. Depending on the power supplied by the power source 12, the power converter may include a DC / DC converter or an AC / DC converter or an electronic circuit for converting power.

[0129] The power processing first device 21 is preferably located within the medical or dental equipment part 1, so as to process the power supplied from the power source 12 for several or all of the elements of the medical or dental equipment part 1 that are to be powered. Thus, in the embodiment shown in Figures 6 to 8, the power processing first device 21 processes power for at least the medical or dental equipment part controller 5B and the electromagnetic wave emitting device 2, and optionally processes power for at least one sensor 10, if the sensor 10 requires power for its operation.

[0130] Preferably, the power supply 12 supplies constant voltage or direct current power to a power processing unit 21 which includes a DC / DC converter configured to convert the voltage level of the power supply 12 to a different voltage level. The power processing unit 21 may alternatively or additionally comprise a filter for compensating for transmission interference of the power supplied from the common power supply 12 via the first and second common lines 6A, 6B.
