Definitions
- the present disclosure relates to a computer-implemented tracking method for tracking a sterile cycle history of a medical product, in particular an instrument or a medical device with a motor system.
- the present disclosure relates to a tracking system, a universal adapter for tracking a sterile cycle history, an ultrasonic sieve, a computer-readable storage medium and a computer program according to the preambles of the independent claims.
- medical devices such as surgical instruments or surgical equipment are subject to strict processing, care and sterilization requirements. They go through a so-called sterile goods cycle.
- Such a sterile goods circuit for a medical device such as a surgical instrument or device with a motor system has or consists of the following process steps in particular:
- Process step manual or mechanical pre-cleaning of the medical device, in particular by means of ultrasound;
- 2nd process step disinfection of the medical device
- Process step the medical application or the actual use of the medical device, especially during a surgical procedure.
- Such a sterile goods circuit/sterile goods cycle is repeated until the medical device is either defective or has exceeded its specified service life and must be replaced.
- ID unique identification
- a further Part of the task is to ensure the guaranteed availability of medical products in the sterile goods cycle, preferably in the operating room, in order to prevent surgical delays and cancellations and thus increase the safety of an intervention and also minimize costs.
- the objects are achieved with regard to a tracking method by the features of claim 1, with regard to a tracking system by the features of claim 9, with regard to a universal adapter by the features of claim 10, with regard to an ultrasonic sieve by the features of claim 12, with regard to a computer-readable storage medium by the features of claim 13 and with regard to a computer program by the features of claim 14.
- a basic idea of the present disclosure therefore provides for the use of "data points" or process steps in the sterile goods cycle which have a maximum influence on the service life of a medical device and thus its availability, in order to ultimately ensure “guaranteed availability", i.e. to keep the medical devices available for a medical procedure which still have a sufficient or adequate service life so that they do not become defective during use.
- the mechanical pre-cleaning using ultrasound and product care, in particular oiling the medical device were identified as such relevant data points with a significant influence on the product quality, in particular a motor system of a medical device.
- an incremental counter for the respective medical device in particular in the respective handpieces, can then be increased step by step (plus one), in particular by means of an antenna.
- this collected data can be used to make a statement about a service life based on the data already collected and on the basis of predictive models, for example based on historical data on a medical device's service life, a statement about future availability and, if applicable, failures.
- This can be used to issue a warning message or initiate an automated recovery process. For example, an automated repair of a repair system for the medical device can be started. A reorder or a repair or another action to remedy the shortage can also be triggered fully automatically.
- Minimum requirements are defined with regard to the service life of a medical device in order to guarantee and ensure the guaranteed availability in the customer's hospital. This can achieve an availability of over 90%.
- a computer-implemented tracking method for tracking a sterile cycle history of a medical device, in particular an instrument or a medical device with a motor system, which has the steps: detecting a unique identification of the medical device by a detection unit, in particular an identification number stored in a transponder of the medical device by a transponder read-write device; reading in a sterile cycle history counter associated with the medical device with identification; detecting an ultrasound treatment of the medical device and/or care, in particular oiling, of the medical device and increasing the sterile cycle history counter associated with the medical device (incrementally, i.e.
- the counter stored in the transponder in the step of reading the sterile cycle history counter, in addition to reading (reading out) the identification number from the transponder, the counter stored in the transponder can also be read; and in the step of storing the counter, the counter is stored in the transponder associated with the medical device.
- the counter associated with the medical device is stored directly in the medical device.

- the tracking method can be adapted to read in a sterile cycle history counter stored on a central server (for example data from a cloud) in a storage unit associated with the medical device in the reading step; and in the counter saving step, the incrementally increased counter is stored in the storage unit of the central server for the medical device with the identification in order to provide central data management of the sterile goods history of the medical device, in particular for a large number of different medical devices.
- a central server for example data from a cloud
- the incrementally increased counter is stored in the storage unit of the central server for the medical device with the identification in order to provide central data management of the sterile goods history of the medical device, in particular for a large number of different medical devices.
- each database entry comprising at least one identification number, an associated counter and a predefined limit value for the counter
- the runs of the sterile goods cycle of each medical device can be recorded via the associated counter and, for counters greater than equal to the limit, the warning message is issued or the recovery process is started.
- the predefined limit value can be defined as less than a service life of a number of sterile goods cycles associated with the medical device, so that a warning message is issued to a user and/or the automated recovery process is started before the end of a service life is reached. This gives the user enough lead time to prepare the medical device and restore its functionality or to exchange the medical device for a new one, for example in an automated logistics system with medical devices kept in stock.
- both an ultrasound counter as the first counter and a care counter as the second counter can be stored for the medical device, and in the event that both an ultrasound treatment of the medical device and a care of the medical device are detected, the counters are each increased by one or, if the ultrasound treatment is detected, only the ultrasound counter is increased accordingly and if the care is detected, only the care counter is increased accordingly and it is determined that the medical device is in the warning range if at least one counter exceeds a predefined limit value.
- a (first) predefined limit value for ultrasound and a (second) predefined limit value for care can be stored for the medical device or a class of a medical device, for example a surgical scalpel.
- a sum of the ultrasound counter and the care counter can be created, and if this sum exceeds a predefined limit value, it can be determined that the warning range exists.
- the counter can only be increased by one. This ensures that with only one The counter can be increased by one per run.
- the counter can be increased by exactly one.
- exactly one run is recorded and the counter is increased accordingly.

- LIDAR device light detection and ranging
- LADAR light detection and ranging
- the tracking method may further comprise the step of determining the state: transmitting the recording to a trained AI system (Artificial Intelligence System) of a central server, which is associated with a cutting edge quality of a surgical instrument as input data and a state determination, in particular a binary state determination "sufficient” - “inadequate” (1 -0; state good - state insufficient), and carrying out a determination of a state by the trained Kl system; wherein further preferably a transmission of the determined state to the multi-reader/multi-read-write device is carried out.
- a trained AI system Artificial Intelligence System

- the data can preferably also be recorded at the customer's premises. This can be done in particular (in addition to manual notes and subsequent digitization in order to be able to use the data) by directly recording and storing (logging) in a computer environment (with the appropriate computer program) in order to be able to use the data later.
- the prerequisite for this is that the data points are logged/generated by the customer and must be made available to the manufacturer in order to then derive actions based on them. This can be used to guarantee availability as a service. This represents the minimum requirement for the recording of data at the customer's premises.
- a partially automated tracking method can be used which, with the aid of different electronic components, records at least some of the process steps, in particular all process steps, of the sterile goods cycle (automatically).
- a tracking system for tracking a sterile cycle history of a medical device, in particular an instrument or a medical device with a motor system, in that the tracking system has: a recording unit which is adapted to provide a unique identification of the medical device, in particular an identification number stored in a transponder of the medical device, by means of a Transponder read-write device or by a camera and a QR code integrated in the medical device; a sensor adapted to detect an ultrasound treatment of the medical device and/or a care of the medical device, in particular oiling; and a control unit adapted to increase the sterile cycle history counter associated with the medical device (incrementally by one) and to store the counter in a storage unit, in particular in the transponder of the medical device by a transponder read-write device; and if the counter exceeds a predefined limit value associated with the medical device, to issue a warning message to a user via a visual display device and/or to start an automated process to restore the functionality of the medical device

- the universal adapter has: an adapter housing with an antenna contact point with two electrical contact surfaces spaced apart from one another, arranged on a top side and exposed to the outside of the adapter housing, in particular with exactly two electrical contact surfaces, for a standardized coupling structure for a signal-related, wired connection to an antenna, a fastening section of the adapter housing, in particular in the form of a ring, in order to fasten the universal adapter to an object, in particular an ultrasonic sieve, and a wired signal interface, in particular a high-frequency coaxial cable, which is conductively connected to the antenna contact point in order to forward a data signal, in particular a high-frequency signal (HF signal).
- HF signal high-frequency signal
- a type of extension cable is therefore provided for connecting an antenna for reading the transponder, but this has a defined connection point, a type of plug, so that the antenna, for example a holder with an antenna, can be connected easily and safely via plug-and-play, for example plugged in or inserted.
- the universal adapter has such a signal interface, which is precisely adapted to transmit the high-frequency signals for the antenna for reading and writing the transponder, so that the antenna is arranged near the medical device with the transponder and can be read in the near field.
- a direct current for example 3V, 5V or 12V, can also be transmitted preferably via the antenna contact point in order to provide a power supply, for example for a medical device connected in the area of the antenna.

- the universal adapter can also have asymmetrically arranged projections on its top to ensure that the mating adapter is aligned in one way. Similar to a USB-A connection, the universal adapter and mating adapter can only be coupled to one another in one orientation. This is particularly important for direct current transmission.
- the signal interface may comprise a shielded coaxial cable for transmitting the RF signals.
- the universal adapter can preferably be designed to be waterproof, in particular it can have a fluid-tight housing that encloses an interior and only the electrical contacts are open to the outside in order to ensure continued functionality during or after immersion in an ultrasonic bath.
- immersion in an ultrasonic bath can be detected via the antenna contact point with the two contact surfaces, as this creates a short circuit between the two contact surfaces and this electrical conductivity of the electrical circuit can be used as a parameter.
- the ultrasonic sieve has at least one universal adapter according to the present disclosure which is attached via its fastening section to the ultrasonic sieve, in particular to a sieve bowl base, and is connected via its signal interface to a central communications unit, so that an antenna that can be connected via the antenna contact point is used to read and/or write a transponder of the medical device.
- the universal adapter thus connects the connection of the communications unit to the antenna for reading the transponder as a type of extension with a defined interface.
- the medical devices can be arranged in different positions in the sieve basket and the antennas for reading and/or writing are placed near them and simply connected via the universal adapter. Since HF signals are also transmitted, there is no need for the laborious screwing on of an antenna cable, such as an antenna to a holder, and the antenna can be connected via plug-and-play.
- the ultrasonic sieve can further comprise a holder with an antenna, wherein the holder is adapted to accommodate and hold, in particular to fix, a large number of medical products, wherein the holder has a counter adapter designed to complement the universal adapter in order to connect the holder centrally to the universal adapter.

- a direct current (DC) can also be transmitted via the signal interface in order to provide electrical energy for the medical device.
- the ultrasonic sieve can be equipped with an electronic module/electronics which is adapted to be able to detect or have at least one of the following properties:
- Bluetooth Bluetooth low energy
- WLAN wireless LAN
- similar transmission modalities in order to be able to communicate with a reading and/or writing device, in particular a multireader;
- An ultrasonic sieve can be provided which does not run through the entire sterile goods cycle and thus does not have to pass the high temperature and high pressure phase of sterilization, so that the electronics of the ultrasonic sieve are suitable accordingly.
- the ultrasonic sieve can in particular have an ultrasonic sensor to detect an ultrasonic bath.
- the ultrasonic sieve can also have a temperature sensor and/or pressure sensor to detect cleaning or disinfection or care.
- the ultrasonic sieve can also have a communication module of the communication unit that is adapted for wireless transmission of data.
- the ultrasonic sieve may be equipped with electronics or a detector adapted to detect the immersion of the ultrasonic sieve in an ultrasonic bath as well as the ultrasonic operation itself.
- the ultrasonic sieve can perform an additional function in combination with the universal adapter or the universal interface, namely an antenna can be contacted via this and thus the data (e.g. the counter) can be written into the transponders (e.g. RFID glass tags).
- the data e.g. the counter
- the handpieces are simultaneously sprayed with oil.
- the ultrasonic sieve could also recognize the process step in the ultrasonic bath and use the data Universal adapter and connected antenna on the holder in the medical devices, especially handpieces.
- the ultrasonic sieve can have a self-sufficient energy source and the power supply of the electronics in the ultrasonic sieve can be solved in particular via a primary cell or via an accumulator which can be charged inductively during the process or is charged in the respective process steps by means of energy harvesting.
- the tracking system of the present disclosure may include a universal adapter and/or an ultrasonic sieve according to the present disclosure.
- the tracking system may further comprise a medical oil sprayer for spraying a medical device (which comprises an engine system) with oil, wherein the oil sprayer comprises a universal adapter according to the present disclosure.
- the multi-reader can be used to identify medical devices. This can be done in particular via a data matrix code (for example QR code) and/or a barcode and/or a transponder, such as an RFID chip.
- a camera system can also be assigned an important function, both for recognizing a data matrix code (QR code) and also preferably, in further steps, for assessing a medical device, such as the cutting quality of a cutting instrument.
- QR code data matrix code
- This evaluation can preferably be used in combination with a Kl algorithm to determine the remaining service life.
- the universal adapter or port itself then reads the individual handpieces and plays the data as an interface into a database, for example into the cloud directly into the respective cloud databases.
- the multi-reader itself could therefore transfer the data via communication (such as BLE, WLAN, etc.). The data could then be transferred to a server or cloud or other via the multi-reader. Programs are loaded and the service life of each individual medical device is logged.
- the multi-reader can also have the universal adapter to provide batch reading of the holders and the medical devices with transponders held on the holders.
- the objects are achieved in that it comprises instructions which, when executed by a computer, cause the computer to carry out the method steps of the tracking method according to the present embodiment.
- the universal adapter as a contact system can be adapted in shape and size, whereby the geometric dimensions in length/width/height can be 30mm/12mm/7mm in particular and are therefore very small in order to be able to be arranged at different points on an ultrasonic sieve or an oil sprayer, for example.
- the disclosure regarding the tracking method of the present disclosure applies equally to the tracking system, universal adapter and ultrasonic sieve of the present disclosure and vice versa.

- the medical device can be uniquely identified and linked to stored data associated with the medical device 1.
- a counter of a sterile cycle history associated with the medical device 1 with identification is read in. After the connection with the relevant data, the associated counter is read in.
- a step S3 an ultrasound treatment of the medical device 1 of the medical device 1 is detected and, as a result, the counter of the sterile cycle history associated with the medical device 1 is incrementally increased by one.
- step S4 the now increased counter is stored in a storage unit 8, in particular in the transponder 4 of the medical device 1 itself by a transponder read-write device 6.
- a step S5 it is determined that the medical device 1 is in a warning range, namely when the counter exceeds a predefined limit value associated with the medical device (1). If the sterile goods cycle for the individual medical device 1 has been run through too often, the state of the medical device 1 can change from a "green” range to a "yellow” range before it reaches a "red” range in which the medical device 1 is unusable. In this case, the "yellow" range of a warning is already recognized that the life expectancy may soon be reached and in a step S6a, a warning message is issued to a user via a visual display device 10, for example in the form of a display.
- an automated recovery process to restore the functionality of the medical device 1 can also be started in a step S6b.
- This sequence of the above steps also takes place at the care station where the medical device is sprayed with oil. However, this only establishes that the counter has already been increased at the ultrasound station, so that no further incremental increase of the counter takes place at this station.
- the counter is only increased when the medical device has passed through both the pre-cleaning station and the care station.
- the counter can also be increased at each of the two stations, although in this case a cumulative predefined limit is also used to take this into account.
- the two decisive stations are each marked with an asterisk.
- Fig. 2 shows a schematic view of another sterile goods cycle of another variant with a tracking method in which a run is recorded at three stations.
- a further station is provided on a so-called multi-reader.
- the multi-reader can also detect a run and can be provided instead of or in addition to the other two stations for pre-cleaning and care.
- Figs. 3 to 6 show an ultrasonic sieve 101 with a central communication unit 102 and two connected universal adapters 12 for a contact-based connection of instruments and in Figs. 5 and 6 the universal adapter 12 separately, in particular for a tracking system according to a preferred embodiment with a control unit.
- the ultrasonic sieve 101 shown in Fig. 3 without medical devices 1 and in Fig. 4 with holder and medical devices, is intended and designed to hold medical devices 1 and immerse them in an ultrasonic bath.
- the ultrasonic sieve 101 has two universal adapters 12 according to a preferred embodiment, each of which is fastened to a sieve bowl base 102 via its fastening section 24 and to a central Communication unit 104 is connected.
- This communication unit 104 can exchange data wirelessly via WLAN or Bluetooth with a data interface in order to be able to access stored data on the medical devices 1.
- a connectable antenna (14) can be used via the universal adapter 12 for reading and/or writing a transponder (4) of the medical device (1).
- the ultrasonic sieve has an electronic module with a temperature sensor and an ultrasonic sensor in order to detect immersion and ultrasonic treatment.
- the universal adapter 12 is described in more detail with reference to Figs. 5 and 6.
- the universal adapter 12 is used for coupling an antenna 14 for tracking a sterile cycle history of a medical device 1.
- it has an adapter housing 16 with an antenna contact point 18 with exactly two electrical contact surfaces 22 spaced apart from one another, arranged on an upper side 20 and exposed to the outside of the adapter housing 16, in order to be able to produce a standardized coupling structure for a signal-technical, cable-based connection to an antenna 14.
- the universal adapter also has a fastening section 24 of the adapter housing 16 in the form of a (screw-on/fastening) ring in order to fasten the universal adapter 12 to the sieve bowl base 102 of the ultrasonic sieve 101.
- the universal adapter has a wired signal interface 26 in the form of a high-frequency coaxial cable, which is conductively connected to the antenna contact point 18 in order to forward a high-frequency signal and thus control the antenna 14.
- the universal adapter 12 has magnets 28 to provide a force-fitting, detachable coupling with the universal adapter 12, in particular for a counter adapter 110 of the holders 106 that is designed to be complementary to the universal adapter 12.
- the universal adapter 12 has two spaced apart magnets 28 that are aligned parallel to each other but with opposite magnetic polarity in order to ensure a unique alignment of a connection, namely to a counter adapter 110 with complementarily arranged magnets.
- the universal adapter 12 has three asymmetrically arranged projections 30 which prevent incorrect alignment when connected to the mating adapter 110.
- a tracking system with a control unit (not shown) according to a preferred embodiment is already implemented.
- the detection unit which is adapted to provide a unique identification of the medical device 1, in particular an identification number stored in a transponder 4 of the medical device 1, is implemented by the transponder read-write device 6.
- the sensor which is adapted to detect an ultrasonic treatment of the medical device 1, is implemented by the electronic module with a temperature sensor and an ultrasonic sensor in order to detect immersion and ultrasonic treatment.
- a control unit (not shown) of the tracking system is adapted to increase the sterile cycle history counter associated with the medical device 1 (incrementally by one) and to store the counter in a storage unit, in particular in the transponder 4 of the medical device 1 by a transponder read-write device; and if the counter exceeds a predefined limit value associated with the medical device 1, to issue a warning message to a user via a visual display device 10 and/or to start an automated process for restoring the functionality of the medical device 1.
- Fig. 7 shows a multi-reader for a tracking system, which has a universal adapter 12 in the middle of a base in order to be able to read medical products 1 arranged on a holder with antennas 14, which are designed similarly to the ultrasonic sieve 101 above.
- a defined standardized interface of a recording unit in the form of a transponder read-write device can be provided via the universal adapter 12.
- the multi-reader is thus adapted to record the unique identification of the medical product 1 or the medical products 1, which is stored as an identification number in a transponder 4 of the medical product 1.
- a tracking system according to a preferred embodiment, which comprises the multi-reader of Fig.
- a control unit (not shown), which can be provided for example in the multi-reader, is specially adapted to increase the sterile cycle history counter associated with the medical device 1 (incrementally by one) upon detection and to store the counter in the transponder 4 of the medical device 1 by the transponder read-write device.
- control unit is adapted to issue a warning message to a user via a visual display device (not shown here) and/or to start an automated process for restoring the functionality of the medical device 1 when the counter exceeds a predefined limit value associated with the medical device 1.
- Figs. 8 and 9 show an oil sprayer 108 which has a counter adapter 110 which is complementary to the universal adapter 12. This allows the oil sprayer to be connected to the care station via a universal adapter and a counter for the medical device to be increased.
