Description

[Technical Field]

[0001] The present disclosure relates to a smart accumulator for a medical electrical appliance / application unit, as well as a medical treatment system or device consisting of a medical appliance / application unit, at least one accumulator or electrical energy storage unit, a charging station, and a display device separate from the medical appliance. [Background technology]

[0002] In medicine, especially surgery, medical instruments such as drills, grinders, saws, etc., as well as other types of equipment such as pumps, life support machines, measuring devices, etc., are frequently used, which utilize batteries or accumulators as the primary (mobile) energy source to operate the electrical equipment / gears / components of the respective instruments so as not to be dependent on stationary energy sources such as the power grid. Such batteries / accumulators are usually configured as "built-in" units, i.e., so-called battery blocks, which can be inserted into a correspondingly shaped battery housing / compartment in / on the instrument, which can be closed via a lid. In this way, the inserted battery / accumulator is sealed from the instrument's environment, thereby ensuring sterility.

[0003] In particular, when an instrument is subjected to a sterilization process after use, the inserted battery / accumulator may be damaged or destroyed, so it is important that the accumulator can be replaced. This means that each battery or accumulator is removed from the instrument housing before such a sterilization process and charged in a charging station during the sterilization process.

[0004] It should be noted at this point that medical electrical appliances or their functions must be controlled / regulated in some way, requiring corresponding control electronics, and that despite the placement of such electronics, consideration must be given to ensuring that the electronics are not damaged and that the sterility of the medical electrical appliance is guaranteed.

[0005] For example, in the case of medical electrical appliances for connection to a static power supply, this can be practically easily achieved by integrating the medical appliance electronics into a power supply unit that is connected to the static power supply. However, this is not possible in accumulator-operated appliances (which do not have a static power supply unit). In this case, the respective electronics are therefore integrated into a battery or accumulator, and are then removed from the appliance together with the battery for sterilization.

[0006] Furthermore, surgical instruments are designed for a wide range of uses, where the increased energy demands mean that an empty accumulator in an instrument, especially a drill, poses a significant risk to the patient, as instruments are not meant to be replaced, much less the accumulator, which takes time and carries the risk of losing sterility.

[0007] For example, International Publication No. WO 2006 / 111773 discloses a hand-operated, accumulator-operated surgical instrument that integrates a battery / accumulator and control electronics for driving / regulating the instrument's electric motor. Furthermore, in the related field of DIY machine technology, there are electric machine tools, such as drills and screwdrivers, in which a battery block for operating the electric motor is docked to each handle. The batteries can be equipped with smart features, such as voltage, current, temperature, and / or state-of-charge detection means / sensors, and these measurements can be transmitted to a control unit via a wireless communication device and displayed, for example, on a mobile phone. However, in such machine tools, the accumulator wears out relatively quickly, and therefore replacement costs must be minimized. Therefore, the control of the internal motor is usually integrated into the machine tool. Furthermore, machine tools are not sterilized.

[0008] Furthermore, there is a need for a system that notifies the surgical team in a timely manner when the accumulator is low. If this information is available early enough, an appropriate non-critical moment can be chosen to replace the accumulator with a new one. In known prior art, the accumulator and electronics are located inside the application or medical instrument, making it impossible to inform the user or operator of the device status via an optical display.

[0009] Displays showing the remaining capacity of an accumulator and other operating parameters are known from the prior art and are used in DIY appliances and other battery-powered devices. The electronic intelligence is located in the respective application part / medical instrument, which makes sterilization of the application part / medical instrument difficult in the medical field. In the known prior art, the charge state of the accumulator can only be read while it is being charged in the charging station. If the accumulator is outside the charging station or inside the application part, this is an unknown variable. Until now, such displays of operating parameters have only been known for wired devices. Summary of the Invention [Problem to be solved by the invention]

[0010] Based on this prior art, it is an object of the present disclosure to provide a smart accumulator for an electrically operated medical instrument / application part, preferably of the portable instrument type, and a medical treatment system comprising such a medical instrument / application part, which can reduce / eliminate sterilization issues in particular. [Means for solving the problem]

[0011] This object is solved by a smart accumulator having the features of claim 1 and by a medical treatment system having the features of claim 10. Advantageous embodiments of the present disclosure are therefore subject matter of the dependent claims.

[0012] The present disclosure therefore relates to a medical smart accumulator (smart accumulator block), in particular a medical instrument / application part for powering an electrical device, preferably an electric motor, inside the instrument, the smart accumulator comprising an accumulator / accumulator block integrated control electronics for driving the entire electrical device inside the instrument, preferably in response to an actuation signal from an operator, a number of smart functions including associated sensor systems and integrated intelligence consisting of at least protection circuits, motor regulation and wireless communication interfaces.

[0013] In other words, the smart accumulator / smart accumulator block is equipped, on the one hand, with control electronics for driving in particular an electrical device / component, in particular an electric motor of a medical device / application, and, on the other hand, with smart functions including the associated sensor system. Preferably, the corresponding measured values ​​can be transmitted to a display device / external interface (with a receiving device) via the accumulator / accumulator block integrated data transmission device. This means that a battery / battery block or an accumulator / accumulator block for a medical device / application preferably includes all control and smart functions for controlling and / or regulating as well as monitoring the electrical device / component (e.g., electric motor) of or therein the medical device and / or the battery or accumulator itself.

[0014] The control electronics attached to / integrated in the smart accumulator / smart accumulator block has the advantage that the application part / medical device has a control-free drive unit. Furthermore, it is preferred that the control electronics are arranged on at least one printed circuit board fixed to or in the accumulator / accumulator block. Furthermore, it is preferred that the wireless communication interface is arranged on a first printed circuit board and the protection circuit is arranged on a second printed circuit board, the first printed circuit board preferably being fixed to the foot end of the accumulator / accumulator block and the second printed circuit board preferably being arranged longitudinally transverse to the accumulator / accumulator block.

[0015] The accumulator / accumulator block may be formed or composed of several (bundled) power storage cells. An accumulator head / housing is preferably arranged on the side of the accumulator / accumulator block opposite the first printed circuit board, housing the accumulator or individual power storage cells. The accumulator head preferably has a cable receptacle or cable shaft for electrically connecting the poles of the accumulator / accumulator block or individual power storage cells to the first printed circuit board and / or the second printed circuit board.

[0016] This has the advantage that the accumulator / accumulator block can be inserted or replaced in the device early enough and at a suitable time to inform the operating team or the user / operator in time about critical states of the smart functions, in particular the accumulator charge state.

[0017] Here, the smart functions preferably include at least one of the following functions: detecting the charging state, the temperature of the accumulator / accumulator block and / or the medical device / application part, the rotation speed of the device motor, the current consumption of the electrical device, preferably the electric motor, the voltage, the output power of the device motor, and / or the installation state in the device or in the receiving compartment of the device / application part, and activating the control electronics / electrical device from a power-saving sleep mode.

[0018] This has the advantage that an external interface, preferably a monitor, can be used to display the accumulator charge state as well as the other parameters mentioned above and to query them if required.

[0019] Furthermore, the medical instrument / application part preferably comprises a handle part having a receiving compartment / receiving shaft for actuating the medical instrument, and the smart accumulator is provided and configured to be insertable and / or pluggable into the receiving compartment.

[0020] Furthermore, the smart accumulator / accumulator block preferably comprises a data memory provided and configured to store the load history and / or transmit it to a display device in order to determine and / or detect the remaining useful life and / or operating behavior and / or occurred faults of the respective accumulator based on the transmitted data.

[0021] In other words, the smart accumulator / accumulator block may also be provided with a data memory that stores a load history, such as the number of charging cycles and / or the state of deep discharge, and this load history may also be transmitted to the display unit, so that the transmitted data can be used to draw conclusions, for example, regarding the remaining useful life of the respective accumulator. The displayed operating parameters thus provide information on the operating behavior and any errors. Overloading of the medical device can therefore be identified during ongoing operation / application. Forecasting the remaining operating time and the remaining charge of the accumulators allows for a more planned and reliable operating process, which also ensures increased safety for the patient.

[0022] This means that not only is the state of charge known, but it is also possible to predict how long the device can still operate with this accumulator / accumulator block. This is advantageous because it can be predicted as a function of load based on stored load history and stored data, and therefore represents a reliable value. This prevents unpredictable degradation of the service life.

[0023] Specifically, sensors specific to / assigned to the smart function are integrated into the accumulator / accumulator block, and their measurements are preferably transmitted / transmitted to an integrated intelligence consisting of a protection circuit, electrical equipment regulation (e.g., motor regulation), and a wireless communication interface, allowing the instrument / application unit itself to remain completely free of integrated electronics. In other words, the intelligence is fully integrated into the accumulator / accumulator block. Therefore, during use, the accumulator / accumulator block is completely enclosed in the application unit / medical instrument and cannot project visual instructions externally for the user, which is why the wireless communication interface is necessary. This allows for maintaining sterility. Therefore, because the application unit / medical instrument (itself) is completely free of integrated electronics, it can be easily sterilized, for example, by steam sterilization, without damaging the electronic components.

[0024] A wireless communication interface is preferably provided and configured to be integrated into the bottom surface of the smart accumulator / accumulator block as an antenna for communication with the outside of the application part / medical device, and to transmit data transmitted through the lid of the application part that encloses the inserted smart accumulator / accumulator block in the receiving compartment.

[0025] All necessary operational data is preferably exchanged via wireless communication paths between the medical instrument / application unit, the charging device and an external interface, preferably an electronic display, which displays current operational data and data from the history of the respective accumulator(s).

[0026] In other words, the antenna representing the communication interface to the outside world is located at the bottom of the accumulator / accumulator block and therefore transmits through the lid to the remote station / external interface.

[0027] Furthermore, the wireless communication interface is preferably a radio transmission interface conforming to the Bluetooth (registered trademark) Low Energy standard in the 2.4 GHz band.

[0028] Furthermore, a smart accumulator / accumulator block is preferably provided and configured to communicate the type of accumulator / accumulator block to the charging station when plugged in to set an accumulator-specific charging curve, and the charging station is preferably provided and configured to regulate the charging of the accumulator / accumulator block. In other words, the smart accumulator may include an accumulator identifier for identifying the accumulator type, which can be read, for example, by the charging station, which then selects an accumulator-specific charging cycle (corresponding to the associated charging curve). In other words, the type of accumulator / accumulator block is communicated via wire to the charging device when plugged in. Based on this information, the charging device sets the correct charging curve depending on the accumulator type. Charging intelligence is entirely on the charging device side, which also allows for charging regulation.

[0029] Furthermore, the integrated intelligence is preferably provided and configured to recognize the direction of rotation of the electric motor, so that the motor is started by a key and the direction of rotation can be changed / reversed by simultaneously pressing and holding a second key. This has the advantage that there is no need to constantly press the reversing button. In other words, the direction of rotation of the motor or of the tool attached to the implement / application part, respectively, is detected.

[0030] A smart accumulator / accumulator block is also preferably provided and configured to automatically set the accumulator integrated control electronics into a power-saving sleep mode when removed from the receiving compartment. In other words, through the detection that occurs when the accumulator is in the receiving compartment of the application part / medical device, it is ready to wake up and communicate with the process or electronics / components. As soon as the accumulator / accumulator block is removed from the machine or receiving compartment, the electronics or process are put into a power-saving sleep mode / hibernation in order to achieve the longest possible accumulator life.

[0031] Furthermore, it is preferable that the application part / medical device is made / manufactured from a suitable material that allows the application part / medical device to be completely sterilized and / or reprocessed. For this reason, the material of the application part / medical device is preferably titanium. In the present disclosure, the smart accumulator / accumulator block is always non-sterile and is placed in the receiving compartment of the application part / medical device. The smart accumulator / accumulator block is fixed and enclosed / sealed via a lid, which is preferably made of plastic and is also sterilized. In this way, the material of the lid is different from that of the application part / medical device. This ensures data transmission.

[0032] Furthermore, the present disclosure relates to a medical instrument / application part of the handheld instrument type, preferably a surgical drill / milling instrument, having a smart accumulator / accumulator block according to any of the preceding aspects.

[0033] Furthermore, the present disclosure relates to a medical treatment system comprising a medical instrument / application portion according to the preceding aspect, an accumulator charging device, and a display device.

[0034] Furthermore, the present disclosure relates to a modular smart accumulator / accumulator block for a medical instrument, preferably according to one of the preceding aspects of the present disclosure relating to the power supply of an electric device inside the instrument, preferably an electric (instrument) motor, comprising a device terminal unit including smart functionality (according to the above definition) and an accumulator pack module including accumulator integrated control electronics (battery management system), optionally protection circuits, accumulator cells and optionally an antenna for data transfer (preferably via Bluetooth®), wherein the device terminal unit and the accumulator pack module are connected via a detectable mechanical-electrical (and electronic) coupling mechanism.

[0035] This modular smart accumulator may be claimed independently / separately from claim 1 or any preceding aspect of this disclosure. Additionally, the following aspects may also be claimed independently / separately from the present set of claims.

[0036] In other words, this provides an accumulator that is separable / detachable per se. That is, the accumulator pack module (including the accumulator cells and the battery management system / control system) can be separated from the device terminal unit, including smart functions such as data communication electronics and control electronics for the medical device (in which the accumulator is inserted), if applicable, and these two components can be maintained or replaced independently of each other. This has the advantage that when the accumulator cells are worn out, only the accumulator pack module itself can be replaced, and the device terminal unit with its included smart functions (as a reusable assembly) can be connected to a new accumulator pack module (as a disposable assembly). In this way, there is the possibility of performing authorized battery construction services at the end of the life cycle. Modular smart accumulators also offer the advantage of easy and pluggable disassembly / assembly of the two assemblies, especially if the detachable coupling mechanism has a screw or bayonet lock. Adhesion or riveting are preferred alternative or additional fastening options. This cost savings is possible by upgrading only the accumulator pack module and connecting it to the original device terminal unit, as the device terminal unit is the more expensive component of the smart accumulator due to its smart functionality.

[0037] In other words, the accumulator is a modular, platform-based secondary battery that is preferably configured / able to be detachable from the application / medical device via a releasable closure / coupling mechanism.

[0038] The accumulator pack module preferably has cell holders, preferably three cell holders, which are provided and arranged to hold together accumulator cells, preferably three accumulator cells, in the form of a cell block by fastening the accumulator cells in recesses in the cell holder provided for this purpose.

[0039] Advantageously, the device terminal unit and the accumulator pack module are mechanically connectable to one another via a bayonet lock.

[0040] Advantageously, the accumulator pack module includes an interface module configured for mechanical and electrical / electronic connection to a device terminal unit.

[0041] Preferably, the interface module has contact pins on one side for electrical contact with the accumulator cells and on the other side having contact surfaces that can be brought into contact with corresponding contacts on the device terminal unit when the interface module is mounted on the interface module to supply the device terminal unit with voltage from the accumulator cells. The interface module also preferably has a (centrally located) sleeve receptacle (central bore) for receiving a (contact) sleeve, the sleeve being provided and configured to provide electrical / electronic connection between the accumulator pack module or its battery management system and, where applicable, the antenna and the device terminal unit or its control electronics / smart functions.

[0042] Advantageously, data cables and / or communication buses can be routed through the sleeve.

[0043] Advantageously, the data cable or communication bus can also be connected to the device terminal unit via a plug connection.

[0044] Instead, the (contact) sleeve itself preferably has axially offset contacts to provide electrical contact between the control electronics and the battery management system, and possibly an antenna for data transfer when connecting the device terminal unit and the accumulator pack module, preferably via a bayonet lock, and the plug contact on the device terminal unit side has a jack connection which can be or is plugged into the sleeve when the device terminal unit is mounted with the accumulator pack module.

[0045] If the contact pins are provided with respective wave spring washers on the side facing the device terminal unit, it is advantageous for the contact pins to support the action of the force exerted on the accumulator cell and / or the contacts on the device terminal unit when closing the mechanical, preferably bayonet, lock.

[0046] The accumulator pack module preferably comprises a battery management system with the above-mentioned second printed circuit board fixed, preferably screwed, to a battery management holder / printed circuit board holder, which can be inserted into conductor grooves provided on or in the cell holder by means of axial and longitudinal conductor rails / guide rails.

[0047] The contact pins are preferably located in ring-shaped recesses in the interface module which, when mechanically closed, preferably via a bayonet lock, precisely fit and seal against the bottom surface of the device terminal unit, i.e., the side facing the accumulator pack module, thereby enabling voltage supply to the device terminal unit.

[0048] Advantageously, the jack plug has a number of flat / shaft portions that contact corresponding flat / shaft portions in the (contact) sleeve, maintaining these electrical connections during mechanical and preferably rotational movement when the bayonet lock is closed.

[0049] In other words, the modular smart accumulator advantageously consists of a spacer / cell holder, a protection circuit, a jack connection, a bayonet lock, and a locking mechanism. It is also advantageous here that the (smart) universal energy unit offers the option of adapting different cell variations for several applications in the future via adapters. The spacer / cell holder is provided to receive the battery management system holder via leading rails and to better ensure the retention of the (accumulator) cells in the power supply unit. Furthermore, the spacer / cell holder is variable and preferably a three-part spacer / cell holder. Preferably, three cylindrical battery cells / accumulator cells are used.

[0050] In addition to its protection function, the protection circuitry is preferably configured to exchange data with the application and / or charging device over a one-wire connection.

[0051] Advantageously, a jack plug or connector is provided and configured to transmit data and power.

[0052] A communication interface / interface module is also preferably provided and configured to activate user-based settings, such as, inter alia, maximum rotation speed, multiple charging processes, and / or data transfer. Advantageously, the interface module has a three-pole socket into which the device terminals of the application or medical device engage. In this way, voltage connections as well as ground and data lines can also be connected to the respective application. Here, connections can be made via screw connectors or ribbon cables on the motherboard or via the control electronics (integrated with the accumulator), respectively.

[0053] Advantageously, the housing module has a trapezoidal base and preferably measures 43 x 50 mm.

[0054] Preferably, the components of the power supply are firmly connected to the device terminals of the medical device via the interface module, forming a unit containing a second printed circuit board including a battery management system / battery management holder. The battery management system / second printed circuit board preferably has at least three balancing ICs. In this case, voltage taps for the individual cell voltages, i.e., the voltages of the individual battery cells / accumulator cells, as well as the total voltage of the at least three cells forming the accumulator, are connected in series from the battery management system / second printed circuit board via low-ohm, square-shaped connections by copper or aluminum lightning protection elements.

[0055] A low-ohm connection is especially important for sensor systems, e.g., for detecting rotational speed, as well as for connecting the power electronics of accumulators or smart accumulators found in accumulator-integrated control electronics with the head of a medical instrument or the head of an electric motor of a medical instrument. The low-ohm connection to the device / application is realized here via a rotary bayonet lock. The rotary mechanism can be mounted on the medical instrument in a basic state by the power supply unit with the help of an interface module.

[0056] Preferably, the battery management system / second printed circuit board is firmly screwed into the battery management system holder, and the interface module is pressed, glued, and / or welded to the module housing of the accumulator pack module to form a self-contained accumulator block.

[0057] This allows the units (accumulator block and device terminal unit) to be connected to each other with a small rotational movement, for example clockwise. As soon as this is done, the device terminal is rigidly connected to the remaining accumulator unit in an end position. To release this end position, at least one opposing spring force must be applied to the device terminal. The lock can be reversed by a counterclockwise rotational movement of the connection mechanism. The device terminal may be a control unit in the accumulator head or another unit in the energy platform equipped with an identical device terminal. The disconnect / connect mechanism between the units remains the same.

[0058] Furthermore, an approved opening mechanism is provided by attaching a universal lock to a housing module, which is preferably provided and configured with a bolt lock to prevent rotation of said opening mechanism.

[0059] Furthermore, it is advantageous if the bayonet lock is provided and configured to be protected against unauthorized opening by mechanical coding of the rotational movement in the three bayonet slots. Alternatively, a mechatronic system is preferred, which initializes the closing mechanism, for example via an RFID chip.

[0060] The housing material of the accumulator module is preferably made of plastic, preferably V01. Alternatively, other housing materials such as aluminum are also envisaged.

[0061] Each cell holder is preferably configured to receive a battery cell / accumulator cell, preferably three battery cells / accumulator cells, via clamping engagement, and to this end the cell holder advantageously has at least three clip modules that are rolled up to accommodate the battery cells / accumulator cells.

[0062] Advantageously, the battery management system holder can be inserted into a guide groove provided in each cell holder / spacer via a longitudinal leading / guide rail of the battery cell / accumulator cell.

[0063] In summary, the present disclosure relates to a smart accumulator, a medical instrument / application unit including such a smart accumulator, and a medical treatment system including such an instrument, a charging station, and a display. The smart accumulator integrates the entire control electronics of the medical instrument / application unit and multiple smart functions, in particular the control of the accumulator's charging state and / or the accumulator charging station. Using wireless data transfer, the operating parameters of the accumulator-driven drill can be displayed in the operating room. This increases device reliability and makes operations / applications plannable. Thus, interruptions due to accumulator replacement or the like can be avoided or performed at an appropriate / plannable time.

[0064] Finally, the preceding aspects of the present disclosure create the possibility of providing a kind of accumulator set system consisting of a uniformly designed universal accumulator pack module according to at least one of the preceding aspects and a number of individually designed device terminal units or units equipped with different smart functions, which have the same closure and can be combined with the universal accumulator pack module as needed. This means that the entire accumulator block can be adapted to different medical devices simply by changing the device terminal units, which is quick and cost-effective.

[0065] Hereinafter, the present disclosure will be described in more detail with reference to the accompanying drawings, based on preferred configuration examples. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0067] Examples of the present disclosure will now be described with reference to the accompanying drawings, which are merely schematic in nature and serve to facilitate understanding of the invention, and in which identical elements are designated by the same reference numerals.

[0068] Figure 1 is a schematic diagram of a smart accumulator 1 and its structure according to the present disclosure. The smart accumulator 1 is provided in a medical device / application section 2 (detailed in Figure 4) to power electrical equipment within the device, preferably to drive an electric motor (not shown). The smart accumulator 1 is located on a first printed circuit board 3 and comprises accumulator-integrated control electronics 5 provided to drive the entire electrical equipment.

[0069] The smart accumulator 1 comprises an accumulator 9 which may be formed by one or more power storage cells, at least a first printed circuit board 3 and a second printed circuit board 4 and an accumulator head 15 .

[0070] The accumulator head 15 is located at the top end of the smart accumulator 1, or on the top side of the accumulator 9, or on the individual power storage cells 9 that are bundled together to form a battery pack. The top ends of the accumulator 9 or the individual power storage cells 9 are housed or inserted into the accumulator head 15. Accordingly, a corresponding receiving opening is formed in the accumulator head 15.

[0071] Furthermore, the accumulator head 15 has a cable shaft 17 which is a bushing or a hole for feeding the cable 16 or a portion of the cable 16 into the accumulator head 15 for electrical connection to the accumulator 9 .

[0072] One end of each of the cables 16 is connected to the positive or negative terminal of the accumulator 9, and the other end is electrically connected to the first printed circuit board 3, or alternatively, one end of each of the cables 16 is electrically connected to the first printed circuit board 3 and the other end is electrically connected to the second printed circuit board 4. The electrical connection points can be realized by soldering, plugging in, or the like.

[0073] According to Fig. 1, the first printed circuit board 3 has fixing means 18 provided for fixing the first printed circuit board 3 to the accumulator 9. The first printed circuit board 3 shows a communication interface 6 configured as a Bluetooth® device 20, which is provided for wireless data transfer to an external interface 8. The second printed circuit board 4 in Fig. 1 shows a protection circuit for the smart accumulator 1 and is attached to the side of the accumulator 9. It should be noted that the first printed circuit board 3 and the second printed circuit board 4 may be fixed to the accumulator 9 by gluing / plugging in or by other means.

[0074] Figure 2 illustrates a medical treatment system 14 according to the present disclosure. Figure 2 shows an instrument / application part 2 with an insertable smart accumulator 1, a display device 8, and a charging station or device 12. The smart accumulator 1, the display device 8, and the charging station 12 preferably communicate with each other via Bluetooth®, which allows them to exchange data wirelessly with each other. Alternatively, communication via WLAN or radio is also contemplated.

[0075] A display device 8 is provided and configured to visually display data, parameters or other necessary information, in particular the state of charge. In Fig. 2, the display device 8 represents an electric monitor and has a communication interface compatible with the communication interface 6 of the smart accumulator 1.

[0076] The medical device / application portion 2 has a receiving compartment 7 configured and adapted to receive the smart accumulator 1 (described in more detail in Figure 4).

[0077] The charging station 12 serves to receive the smart accumulator 1 removed from the receiving compartment 7. When the smart accumulator 1 is inserted, the charging station 12 is informed by an electric wire about the accumulator type of the accumulator 9, and is configured to subsequently charge the accumulator 9 with the correct charging curve. This means that the charging station 12 adopts the charging curve. The smart accumulator 1 therefore does not have any charging intelligence. The charging station 12 is also configured to visually display the charging state itself. The charging station 12 also has a communication interface that is compatible with the communication interface 6 of the smart accumulator 1 and the communication interface 6 of the display device 8.

[0078] 3 shows a first printed circuit board 3 on which electrical components and / or sensors are arranged according to the present disclosure. The first printed circuit board 3 preferably has the shape of the bottom surface 10 of an accumulator 9. At least the control electronics 5 or switching regulator, the Bluetooth® device 20, and the preferably ungrounded antenna shielding area 21 are located on the first printed circuit board 3. The printed circuit board 3 is also equipped with and connected to further electrical components that are not illustrated in more detail in FIG. 3.

[0079] 4 is a diagram illustrating the structure of a medical instrument / application portion 2 according to the present disclosure. The medical instrument / application portion 2 includes a receiving compartment 7 formed in the handle portion of the instrument 2 and having a smart accumulator 1 integrated therein, a lid portion 11 located at the lower end of the handle portion and enclosing the smart accumulator 1, at least two operating keys / buttons 13 for allowing a user to operate the instrument / application portion 2, and a tool receiving device 19 configured to receive various attachments such as drills, burrs, etc.

[0080] Furthermore, an electric motor is integrated into the instrument / application part 2, which is powered and driven via a plug-in smart accumulator 1. Preferably, the receiving compartment 7 is made of titanium and the lid 11 is made of plastic. This allows sterilization of the receiving compartment 7 and the lid 11 as well as wireless data exchange via the lid 11.

[0081] FIG. 5 is an exploded view of a modular smart accumulator comprising a device terminal unit and an accumulator pack module. The accumulator pack module has a module housing 22, preferably trapezoidally configured, for accommodating the following components: a printed circuit board holder / battery management system holder 23, preferably configured in the form of a second printed circuit board 4, for receiving the second printed circuit board 4 fixedly, preferably by screws, or for fastening the second printed circuit board 4 to the printed circuit board holder 23 so that the second printed circuit board 4 is fixedly positioned in the printed circuit board holder 23; three cell holders 24 are preferably provided, each having three circular recesses 31, each open on one side to allow a battery cell / accumulator cell 9 to be received in each recess 31 in a ramped manner; and the three cell holders 24 are preferably uniformly spaced along the length of the battery cell / accumulator cell 9.

[0082] Each cell holder 24 has a conductor groove / guide groove 33 on one side, i.e., between the two recesses 31 of the cell holder 24. The conductor groove / guide groove 33 of each cell holder 24 is oriented to receive a conductor rail / guide rail 32 that is slidably inserted in the longitudinal direction. Both the conductor groove / guide groove 33 and the conductor rail / guide rail 32 are preferably rounded. The conductor rail / guide rail 32 is centered on the bottom surface of the printed circuit board holder 23 in the longitudinal direction.
