    Description [0001] The invention relates to a method for monitoring the condition of surgical utensils and similar inserts. The invention also relates to an operating utensil for carrying out the method.
    Especially in medical surgery, the state of the instruments and tools used is one of the decisive factors for the success of the procedures to be performed. In this context, it is a major challenge for clinics, hospitals and other service providers to be able to demonstrate the condition of the operating equipment used at all times in order to avoid mishandling during operations, to investigate possible sources of error, to prove germ destruction or to envisage future regulations (MDR, FDA, etc.). observed.
    The control of the proper state of surgical utensils is done in practice by inspection of the same by the staff providing them and the surgeon performing the procedure, including the assisting staff. It goes without saying that, as a result, this procedure is dependent on the subjective judgment and the individual care of the specialized personnel involved. This control method also has the disadvantage that often a precise reconstruction of the state of the operating implements used in hindsight is no longer traceable.
    The surgical utensils may also be implants, which must also be provided in the procurement and the provision for surgery in an absolutely perfect condition, distinctive and error-free for the patient. This is not guaranteed with sufficient certainty in today's circumstances.
    The invention has for its object to avoid these disadvantages and to provide a method of the type mentioned, which at any time displays and registers the actual state of the used operating utensils, regardless of subjective factors, such as perception errors or lack of care of them providing or using specialist staff.
    This object is achieved according to the invention that the state of the operating utensils is preferably continuously recorded with relevant parameters for their operability parameters with sensors built into them and the data obtained from these data are evaluated at the same time or with a time delay on the basis of instrument-specific target specifications.
    In this way, it is possible to avoid any mishandling of the surgical utensils due to a misjudgment of their condition in surgical procedures, which may otherwise result in the procedure must be repeated to correct the misread surgery, or the Patient sustained damage.
    The inventive method allows the proper use of the operating utensils, which brings a reduction in the error rates with operations. And in case of misguided interventions, it also makes troubleshooting possible based on reliable records of the condition of the operating implements used.
    The process underlying parameters and their target specifications are determined depending on the type and function of the operating tools, in practice factors such as temperature, humidity, momentum, strain, overvoltage, overcurrent, EO concentration, radiation and the like in question come.
    The invention further provides that the evaluation of the data obtained from the operating utensils one or more times, during, before, and / or after use in a connected to the sensors by data transfer means receiver is performed depending on the nature of the procedure.
    For the purpose of a rapid assessment of the recordings obtained, the invention also provides that the evaluation results can be visualized by a suitable means as an interface between the specialist personnel and the hardware, for example a screen device or the like.
    Depending on the complexity of the surgical task, the data received from the surgical utensils are evaluated, preferably aggregated, either on itself or on a database of the recipient.
    In the latter case, the data according to the invention are recorded by a computer or a similar central data processing device, stored and preferably evaluated algorithmically by being compared there with the respectively entered target specifications. The central data processing not only allows an individual assessment of the condition of individual devices, but also an interdisciplinary overview of the overall condition of the equipment used.
    For the evaluation of the data obtained from the operating tools, it is expedient that the computer also takes into account additional application-specific data such as location, date of assignment or duration of the procedure.
    According to the invention, the computer can also register an overloading of the operating utensils by recording the stresses and forces acting on them during use.
    It is also useful for avoiding surgical errors when the computer also registers a damage or even the end of the life of the operating utensils and this is indicated by an optical and / or acoustic signal.
    It is also expedient in this sense, when the computer registered by means of a 3D accelerometer dropping the operating implements from the hand of the surgeon.
    The computer can also register a sterilization or cleaning operation by measuring temperature, humidity and EO concentration.
    The inventive tool for practicing the proposed method is characterized by the fact that miniaturized sensors are installed in it, preferably continuously detect one or more of the parameters to be taken into account. These sensors only slightly change the conventional design of the device. You can transfer the data you have obtained to the receiver via radio via WLAN, Bluetooth, NFC and similar electronic means.
    The sensors can be installed either in an encapsulation or under a cover of the operating utensil. This design also allows the retrofitting of the sensors in conventionally designed devices.
    As a further advantage, the invention provides that this monitoring system is also very useful for implants, and that these implants are respectively provided with one or more sensors. This allows them to be monitored and controlled even before implantation so that no confusion can occur, which also provides additional safety for the surgeons.
    The invention is explained in more detail with reference to several embodiments with reference to the drawings. Show it:
    1 functional and flow diagram of a working according to the inventive method system,
    FIG. 2 shows an instrument designed according to the invention as an operating tool, shown in plan view, FIG.
    3 shows a detail of the instrument from FIG. 2 in the embodiment with an encapsulated sensor, FIG.
    FIG. 4 shows the detail according to FIG. 3 in the embodiment with a sensor arranged under a cover, and FIG. 5 shows a view of an implant designed as a plate as a surgical tool for osteosynthesis.
    The monitoring system shown schematically in Fig. 1 is used for the continuous monitoring of the condition of surgical or medical instruments as operating utensils, such as syringes, forceps, scissors blades, etc., which are exposed depending on the type of intervention different conditions of use and thus during the operation experience different stresses.
    Such surgical utensils may also be implants of any kind, such as plates for osteosynthesis for holding a broken bone, to joint prostheses, pacemakers, stents, vascular prostheses or the like.
    This monitoring system comprises several stations 1 to 7 with different functions, which are networked with each other via a device in the form of a data clouds 8 with the monitored instruments. These compounds are shown schematically in Fig. 1 with solid and dotted lines.
    The station 1 relates to the storage rack of the magazine in which the instruments to be monitored are stored professionally. The station 2 relates to an operating room in which the instruments are used, while the stations 3 to 7 in turn relate to the instruments used in the procedure, the stations 4 to 7 refer to individual features that are relevant to the state of the instruments. Thus, in station 4, the fall of the instruments is registered, in station 5 their cleaning state, in station 6 their sterilization state and in station 7 the end of the life of the instrument.
    Further stations of the system are the station 9 with a device for visualizing the measured values obtained via data clouds and a station 10, in which used instruments are fed to a recycling process.
    The evaluation and registration of the data contained in the data clouds 8 takes place in one or more computers. These are symbolically indicated in Fig. 1 with the station 11.
    The instrument 12 shown in FIGS. 2 to 4 for exerting the monitoring method according to the invention is equipped with two miniaturized sensors 13, 14, which simultaneously contain a data memory, a power supply and a data transmission unit 15. Such sensors allow both the individual evaluation and registration of the data directly on the device as well as the collective evaluation and registration in conjunction with the data of other instruments or sensors.

    In the embodiment of FIG. 3, the sensor 13 is integrated in the instrument 12 in an encapsulation 16, while in the one of FIG. 4, the sensor 14 is disposed under a cover 17. It can therefore be easily dismantled and replaced. In both cases, it is RFID sensors with which preferably different data can be detected. Fig. 5 shows an implant formed as a plate 20, which is provided for example of four interconnected rings 21 to 24 with two webs 25,26. This implant may look different depending on the purpose of use and its dimensions also adapt it to the shape of the bone to be operated on. Through the ring openings 21 'can protrude in a known manner fastened in bone screws. According to the invention, two sensors 27, 28 are integrated in the plate 20, which are advantageously encapsulated and made with such materials that they do not cause any reactions, such as allergies or inflammation, in the human or animal body when they are used. These sensors 27, 28 can perform various functions, for example, if they each contain a force-measuring element, for example a piezo-element, connected to a transponder (RFID), the tensioning force of the plate 20 can be measured with the bone and supplied signals be whether the plate is sufficiently braced with the bone or not too tight. This measurement and signal transmission can take place during, immediately after the operation and / or also after the surgical site has been sewn up. In the embodiments explained above, the instrument 12 to be monitored or this implant is equipped with two sensors. It could be provided in each case only one or more than two sensors. Of course this can vary depending on the type and task of the instrument. The monitoring system according to the invention can be used in so-called single-use instruments as well as in so-called multi-use instruments. In the case of the former, for example, the proof of the feature of sterilization can be demonstrated comprehensibly at the level of each individual unit. For multi-use devices, the circulation can be monitored from the point of sale, use, cleaning, sterilization and reuse. With the monitoring system described, the surgeon can monitor the actual state of the instruments during the period of use and detect possible overuse, which could endanger the course of the operation result. The system can also detect failures due to defective instruments over time. And with further developments, improvements to the product can be incorporated at an early stage. The monitoring system according to the invention can also be used, for example, for monitoring medical disposable consumables. It also allows automatic monitoring of the life of the item. claims
