Beschreibung description
Technisches Gebiet Technical area
Die vorliegende Offenbarung betrifft einen Smart-Akku für ein medizinisches, elektrisches Instrument/Anwendungsteil sowie ein medizinisches Behandlungssystem bzw. eine medizinische Behandlungseinrichtung bestehend aus einem medizinischen Instrument/Anwendungsteil, wenigstens einem Akku bzw. elektrischen Energiespeicher, einer Ladestation und einem zum medizinischen Instrument separaten Anzeigegerät. The present disclosure relates to a smart battery for a medical, electrical instrument / application part and a medical treatment system or a medical treatment device consisting of a medical instrument / application part, at least one battery or electrical energy store, a charging station and a display device separate from the medical instrument .
Hintergrund der Erfindung Background of the invention
In der Medizin, insbesondere Chirurgie werden häufig medizinische Instrumente wie Bohr-, Schleif-, und Sägemaschinen, aber auch andersartige Einrichtungen wie Pumpen, lebenserhaltende Maschinen und Messgeräte verwendet, die eine Batterie bzw. einen Akku als primäre (mobile) Energiequelle zum Betrieb der elektrischen Ausstattungen/Ausrüstungen/Komponenten der jeweiligen Instrumente nutzen, um unabhängig von einer stationären Energiequelle wie z.B. dem Stromnetz zu sein. In medicine, especially surgery, medical instruments such as drilling, grinding and sawing machines, but also other types of equipment such as pumps, life-sustaining machines and measuring devices, are used that use a battery or rechargeable battery as the primary (mobile) energy source to operate the electrical Use equipment / equipment / components of the respective instruments in order to be independent of a stationary energy source such as the power grid.
Solche Batterien/Akkus sind in der Regel als „build-in“ -Einheiten ausgebildet, das heißt, als sogenannte Batterieblocks, die in ein entsprechend geformtes Batteriegehäuse/Fach im/am Instrument eingesetzt werden können, welches mittels eines Deckels verschließbar ist. Auf diese Weise kann eine Sterilität gewährleistet sein, da die eingesetzte Batterie/Akku hermetisch von der Instrumentenumgebung abgeschirmt ist. Such batteries / accumulators are usually designed as “build-in” units, that is, as so-called battery blocks, which can be inserted into a correspondingly shaped battery housing / compartment in / on the instrument, which can be closed by means of a cover. In this way, sterility can be guaranteed, since the battery / rechargeable battery used is hermetically shielded from the surroundings of the instrument.
Wichtig ist hierbei die Auswechselbarkeit des Akkus insbesondere für den Fall, dass das Instrument nach dessen Verwendung einem Sterilisationsvorgang unterzogen wird, der ggf. zu einer Beschädigung oder Zerstörung der eingesetzten Batterie/Akku führen könnte. Das heißt, die Batterie bzw. der Akku wird vor einem solchen Sterilisationsprozess aus dem Instrumentengehäuse entnommen und während des Sterilisationsvorgangs in einer Ladestation geladen. It is important here that the rechargeable battery can be exchanged, especially in the event that the instrument is subjected to a sterilization process after it has been used, which may damage or destroy the battery / rechargeable battery used could lead. This means that the battery or rechargeable battery is removed from the instrument housing before such a sterilization process and is charged in a charging station during the sterilization process.
An dieser Stelle sei darauf hingewiesen, dass medizinische elektrische Instrumente bzw. deren Funktionen in irgendeiner Form gesteuert/geregelt werden müssen, wofür eine entsprechende Steuerelektronik notwendig ist. Dabei ist zu berücksichtigen, dass trotz der Anordnung einer solchen Elektronik die Sterilisierbarkeit des medizinischen elektrischen Instruments gewährleistet bleibt, ohne dass die Elektronik hiervon Schaden nimmt. At this point it should be pointed out that medical electrical instruments or their functions must be controlled / regulated in some form, for which appropriate control electronics are necessary. It must be taken into account here that despite the arrangement of such electronics, the sterilizability of the medical electrical instrument is guaranteed without the electronics being damaged by this.
Bei einem medizinischen elektrischen Instrument zum Anschluss beispielsweise an ein stationäres Stromnetz ist dies in einfacherWeise praktisch umsetzbar, indem die Elektronik für das medizinische Instrument in die am stationären Stromnetz angeschlossene Energieversorgungseinheit integriert wird. Bei einem Akku-betriebenen Instrument (ohne stationäre Energieversorgungseinheit) ist dies aber nicht möglich. Daher wird in solchen Fällen die jeweilige Elektronik in die Batterie bzw. den Akku integriert und demzufolge für einen Sterilisationsprozess zusammen mit der Batterie aus dem Instrument entnommen. In the case of a medical electrical instrument for connection to a stationary power supply system, for example, this can be implemented in a simple manner in that the electronics for the medical instrument are integrated into the power supply unit connected to the stationary power supply system. However, this is not possible with a battery-operated instrument (without a stationary power supply unit). Therefore, in such cases, the respective electronics are integrated into the battery or the rechargeable battery and consequently removed from the instrument together with the battery for a sterilization process.
Zudem sind die chirurgischen Instrumente für ein breites Anwendungsspektrum konzipiert. Hierbei besteht für den Patienten eine große Gefahr, wenn aufgrund eines erhöhten Energiebedarfs der Akku des Instruments, insbesondere der Bohrmaschine leer wird. Ein Austausch des Instruments ist nicht vorgesehen und ein Tausch des Akkus benötigt Zeit und ist mit der Gefahr verbunden, dass die Sterilität verloren geht. In addition, the surgical instruments are designed for a wide range of applications. There is a great risk for the patient here if the battery of the instrument, in particular the drill, becomes empty due to an increased energy requirement. There is no provision for replacing the instrument and replacing the battery takes time and there is a risk that sterility will be lost.
Stand der Technik State of the art
Beispielsweise offenbart die WO 2006/111773 A1 ein Akku-betriebenes chirurgisches Instrument der Handinstrumentenbauart in dessen Batterie/Akku eine Steuerelektronik zur Ansteuerung/Regelung eines elektrischen Motors des Instruments integriert ist. Des Weiteren existieren auf dem entfernten Gebiet der Heimwerkermaschinentechnik elektrische Werkzeugmaschinen wie Bohr-, oder Schraubmaschinen, an deren jeweiligem Handgriff ein Batterieblock zum Betreiben eines Elektromotors angedockt wird. Die Batterie kann mit Smart-Funktionen wie Spannungs-, Strom-, Temperatur- und/oder Ladezustands-Erfassungsmittel/-sensoren ausgerüstet sein, deren Messwerte über eine Drahtloskommunikationseinrichtung an eine Kontrolleinheit übertragen und z.B. auf einem Mobiltelefon angezeigt werden können. Bei derartigen Werkzeugmaschinen ist jedoch die Steuerung des maschinen internen Motors in der Regel in der Werkzeugmaschine eingebaut, da der Akku vergleichsweise schnell verschleißen kann und daher die Ersatzkosten möglichst niedrig gehalten werden müssen. Im Übrigen werden Werkzeugmaschinen keinem Sterilisationsprozess unterzogen. For example, WO 2006/111773 A1 discloses a battery-operated surgical instrument of the hand-held instrument type in whose battery / rechargeable battery control electronics for controlling / regulating an electric motor of the instrument are integrated. Furthermore, in the remote field of home improvement machine technology, there are electrical machine tools such as drilling, or Screwdriving machines with a battery block for operating an electric motor docked to the respective handle. The battery can be equipped with smart functions such as voltage, current, temperature and / or state of charge detection means / sensors, the measured values of which can be transmitted to a control unit via a wireless communication device and displayed on a mobile phone, for example. In such machine tools, however, the control of the machine's internal motor is usually built into the machine tool, since the battery can wear out comparatively quickly and the replacement costs must therefore be kept as low as possible. Incidentally, machine tools are not subjected to a sterilization process.
Des Weiteren wird ein System benötigt, welches dem OP Team rechtzeitig die Meldung erteilt, dass der Akku leer wird. Wäre diese Information früh genug vorhanden, so könnte ein geeigneter unkritischer Moment gewählt werden, den Akku gegen einen neuen auszutauschen. Da sich im bekannten Stand der Technik der Akku und die Elektronik im Inneren des Anwendungsteils bzw. des medizinischen Instruments befindet, besteht keine Möglichkeit mittels optischer Anzeige den Anwender bzw. Bediener über den Zustand des Geräts zu informieren. Furthermore, a system is required which gives the OR team a timely notification that the battery is running out. If this information were available early enough, a suitable non-critical moment could be selected to replace the battery with a new one. Since the battery and the electronics are located inside the application part or the medical instrument in the known prior art, there is no possibility of informing the user or operator about the status of the device by means of an optical display.
Aus dem Stand der Technik sind Anzeigen der Akkurestkapazität sowie weiterer Betriebsparameter bekannt und finden Anwendung in Heimwerkerequipment und anderer batteriebetriebenen Geräten. Die elektronische Intelligenz befindet sich hierbei im jeweiligen Anwendungsteil/medizinisches Instrument, wodurch sich der Sterilisationsprozess des Anwendungsteils/medizinischen Instruments im medizinischen Bereich als schwierig erweist. Im bekannten Stand der Technik kann der Ladezustand des Akkus lediglich während des Ladens an der Ladestation abgelesen werden. Displays of the remaining battery capacity and other operating parameters are known from the prior art and are used in DIY equipment and other battery-operated devices. The electronic intelligence is located in the respective application part / medical instrument, which makes the sterilization process of the application part / medical instrument difficult in the medical field. In the known prior art, the state of charge of the battery can only be read off at the charging station while it is being charged.
Befindet sich der Akku außerhalb der Ladestation oder gar im Anwendungsteil, so ist dies eine Unbekannte. Bisher sind solche Anzeigen der Betriebsparameter nur bei kabelgebundenen Geräten bekannt. If the battery is outside of the charging station or even in the application part, this is an unknown. So far, such displays of the operating parameters have only been known for wired devices.

Eine Prognose über die Restlaufzeit und Restakkuladung machen den Operationsablauf planbar und zuverlässiger. Dies gewährleistet zudem eine höhere Sicherheit für den Patienten. Das bedeutet, dass somit nicht nur der Ladezustand, sondern auch eine Prognose darüber vorhanden ist, wie lange das Gerät noch mit diesem Akku/Akkublock betrieben werden kann. Dies ist vorteilhaft, da basierend auf der abgespeicherten Belastungshistorie bzw. den gespeicherten Daten, die Prognose in Abhängigkeit der Last gestellt werden kann und somit einen zuverlässigen Wert darstellt. Einem unvorhersehbaren Abfall der Restnutzungsdauer kann so vorgebeugt werden. In other words, the smart battery / battery block can also be provided with a data memory in which the load history, such as the number of charging cycles and / or deep discharge states, etc., is stored, which can also be transmitted to the display unit is, so that based on the transmitted data, for example, the remaining service life of the respective battery can be inferred.

An overload of the medical instrument can therefore be checked during ongoing operation / use. A prognosis of the remaining running time and remaining battery charge make the operation process plannable and more reliable. This also ensures greater safety for the patient. This means that not only the state of charge, but also a forecast is available about how long the device can still be operated with this battery / battery block. This is advantageous because, based on the stored load history or the stored data, the prognosis can be made as a function of the load and thus represents a reliable value. In this way, an unforeseeable decrease in the remaining useful life can be prevented.

In anderen Worten kann der Smart-Akku eine Akku-Kennung zum Identifizieren des Akku-Typs enthalten, welche beispielsweise von einer Ladestation ausgelesen werden kann, die dann einen Akku-spezifischen Ladezyklus (entsprechend einer zugehörigen Ladekurve) auswählt. In anderen Worten wird der Typ des Akkus/Akkublocks dem Ladegerät beim Einstecken drahtgebunden mitgeteilt. Auf Basis dieser Information stellt das Ladegerät die korrekte Ladekurve für den Akku-Typ ein.In addition, it is preferred if the smart battery / battery block is provided and designed in order to set a battery-specific charging curve to communicate the type of battery / battery block to a charging station when it is inserted into it, the charging station for regulating the charging of the battery / Battery blocks is provided and designed.

Based on this information, the charger sets the correct charging curve for the battery type.
Die Ladeintelligenz ist vollständig auf der Seite des Ladegeräts. Dieses übernimmt auch die Laderegelung. The charging intelligence is entirely on the side of the charger. This also takes over the charge control.
Des Weiteren ist es bevorzugt, wenn die integrierte Intelligenz dazu vorgesehen und ausgebildet ist, um die Drehrichtung, vorzugsweise des elektrischen Motors, zu erkennen, wobei das Starten des Motors durch eine Taste bewirkt wird und die Drehrichtung durch ein simultanes Drücken und Halten einer zweiten Taste änderbar/umkehrbar ist.

Zudem ist es bevorzugt, wenn der Smart-Akku/Akkublock dazu vorgesehen und ausgebildet ist, um die Akku-integrale Steuerelektronik bei Entnahme aus dem Aufnahmefach automatisch in den stromsparenden Ruhemodus zu versetzen. In anderen Worten bedeutet das, dass mittels einer Erkennung, die aktiviert wird, wenn sich der Akku im Aufnahmefach des Anwendungsteils/medizinischen Instruments befindet, der Prozess bzw. die elektronische Ausrüstung/Komponenten aufgeweckt werden und bereit zur Kommunikation sind. Sobald der Akku/Akkublock aus der Maschine bzw. dem Aufnahmefach genommen wird, wird die Elektronik bzw. der Prozess in den stromsparenden Ruhemodus/Ruhezustand versetzt, um eine längst mögliche Lebensdauer des Akkus zu erreichen. In addition, it is preferred if the smart battery / battery block is provided and designed to automatically switch the battery-integrated control electronics to the power-saving sleep mode when it is removed from the receptacle. In other words, this means that the process or the electronic equipment / components are woken up by means of a detection that is activated when the battery is located in the receiving compartment of the applied part / medical instrument and are ready to communicate. As soon as the battery / battery block is removed from the machine or the receptacle, the electronics or the process are switched to energy-saving sleep mode / idle mode in order to achieve the longest possible service life for the battery.

Zum Lösen der Endposition muss mindestens eine entgegengesetzte Federkraft auf den Geräteanschluss beaufschlagt werden. Durch eine Drehbewegung entgegen des Uhrzeigersinns der Verbindungsmechanismen kann der Verschluss umgekehrt werden. Der Geräteanschluss kann dabei sowohl eine Steuereinheit im Akku-Kopf darstellen, oder als eine andere in der Energieplattform befindliche Einheit, mit identischem Geräteanschluss ausgestattet, verwendet werden. Der Mechanismus zum Lösen/ Verbinden der Einheiten bleibt dabei identisch. In this way, the units (battery block and device connection unit) can be connected to one another by a slight rotary movement, for example clockwise. As soon as this has happened, the device connector is in a fixed connection with the rest of the battery unit in an end position. To release the end position, at least an opposite spring force must be applied to the device connection. The locking mechanism can be reversed by rotating the connecting mechanisms in an anti-clockwise direction. The device connection can represent both a control unit in the battery head or as another unit located in the energy platform with an identical one Device connection equipped, can be used. The mechanism for releasing / connecting the units remains the same.
Ferner ist es bevorzugt, wenn ein autorisierter Öffnungsmechanismus durch die Anbringung eines Universalschlosses in das Gehäusemodul vorhanden ist, welcher durch einen Bolzenverschluss dazu vorgesehen und ausgebildet ist, um die Drehbewegung des oben genannten Öffnungsmechanismus zu verhindern. Furthermore, it is preferred if an authorized opening mechanism is present by attaching a universal lock in the housing module, which is provided and designed by a bolt lock to prevent the rotary movement of the above-mentioned opening mechanism.
Des Weiteren ist es vorteilhaft, wenn der Bajonettverschluss durch eine mechanische Codierung an der Drehbewegung innerhalb der drei Bajonett-Schlitze dazu vorgesehen und ausgebildet ist, um vor unbefugtem Öffnen geschützt zu werden. Alternativ ist ein mechatronisches System bevorzugt, welches bspw. durch einen RFID- Chip den oben genannten Verschlussmechanismus initialisiert. Furthermore, it is advantageous if the bayonet lock is provided and designed to be protected against unauthorized opening by means of a mechanical coding on the rotary movement within the three bayonet slots. Alternatively, a mechatronic system is preferred which, for example, initializes the above-mentioned locking mechanism by means of an RFID chip.
Es ist bevorzugt, wenn das Gehäusematerial des Akkumoduls aus Kunststoff, vorzugsweise V01 , besteht. Alternativ ist ein anderes Gehäusematerial, wie beispielsweise Aluminium, denkbar. It is preferred if the housing material of the battery module consists of plastic, preferably V01. Alternatively, another housing material, such as aluminum, is conceivable.
Vorzugsweise ist jeder Zellhalter derart ausgebildet, um die Batteriezellen/ Akkuzellen, vorzugsweise drei Batteriezellen/ Akkuzellen, mittels einem Klemmeingriff aufzunehmen. Hierfür ist es von Vorteil, dass der Zellhalter zumindest drei Clipmodule aufweist, welche derart rund ausgebildet sind, um die Batteriezellen/ Akkuzellen aufzunehmen. Each cell holder is preferably designed to hold the battery cells / accumulator cells, preferably three battery cells / accumulator cells, by means of a clamp engagement. For this it is advantageous that the cell holder has at least three clip modules, which are designed to be round in order to accommodate the battery cells / accumulator cells.
Es ist von Vorteil, wenn die Batteriemanagementsystem -Halterung mittels einer Leitschiene/ Führungsschiene in Längsrichtung der Batteriezellen/ Akkuzellen in eine Führungsnut einschiebbar ist, welche an jeder Zellhalterung/ jedem Spacer vorgesehen ist. It is advantageous if the battery management system holder can be pushed into a guide groove by means of a guide rail / guide rail in the longitudinal direction of the battery cells / accumulator cells, which is provided on each cell holder / each spacer.
