A storage and processing device has a counter, detects a voltage signal based on the inductively generated energy at each relative movement, increments the counter at each detection of the voltage signal and thereby counts the number of performed manipulation cycles of the instrument.

Description

Technical Field

[0001] This invention relates to apparatus and systems for detecting manipulation cycles of hand-operated instruments, and more particularly to apparatus and systems for detecting, counting and / or recording manipulation cycles in medical instruments (such as scissors, clamps, punches, laparoscopic instruments, etc.) and for providing relevant information obtained therefrom for further processing. Background Technology

[0002] What has been impossible until now is to detect and record manipulation cycles in electronic and / or digital form from the medical field in manually operated, non-powered instruments, and to further process the related knowledge gained on this basis.

[0003] Due to unavailable information, such as such operating cycles, it is also impossible, at least partially automatically, to make statements regarding the general condition of a manually operated product or apparatus, its expected service life or the end of its service life, its performance and suitability for subsequent operation (as described, for example, in the application), and / or current overload and potential damage.

[0004] To date, this has been done through time-consuming and costly testing and visual inspections, which, due to a lack of tested data, have also undergone a series of evaluations that, with safety margins in place, may have prematurely eliminated products and devices, even though they could potentially have been used longer when evaluated based on tested and, in this respect, protected usage data. This, in turn, leads to increased procurement costs and related expenses, as well as the removal of more material than is required for actual use.

[0005] Furthermore, due to the lack of relevant data, it is impossible to create suitable services and business models for customers, which is also not optimal for customers' procurement and operating costs.

[0006] Furthermore, questions about service life and evidence in complaint cases are becoming increasingly meaningful and important. Summary of the Invention

[0007] The objective of this invention is to provide an apparatus and system for detecting manual operation cycles of products or instruments without power supply from the medical field, by means of which a user or customer can directly identify the number of applications that have been performed, that is, to count the number of times a product or instrument without power supply has been manipulated, and whether its intended function can still be fulfilled.

[0008] This task is accomplished by means of a device according to the features of the invention and alternatively by means of another device according to the features of the invention.

[0009] The number of handling cycles is typically a proportional measure of, in particular, the general condition of the instrument, its lifespan or the end of its lifespan, its performance and suitability for the upcoming surgery (as described in the application), as well as its overload and potential product damage. Another measure can be the instrument's handling cycles, which can be determined by combining readable data storage (e.g., RFID chips), NFC, and BLE with a suitable data detection system.

[0010] The overall concept upon which this invention is based is to provide a device that functions as a manipulation cycle counter for detecting manipulation cycles of a medical device that is not manually operated with an energy supply.

[0011] The aforementioned manipulation cycle counter is arranged to count the actuation of the instrument and, in conjunction with an RFID / NFC / BLE module, provides the possibility of displaying the remaining lifespan of the instrument. This detection is based on a sensor device that operates without an external power supply, wherein, during the use of the instrument, detectable or countable and further processed manipulation signals are generated based on the hand movements of the user (e.g., a surgeon).

[0012] The basic idea is that a guided magnet (neodymium (iron boron), samarium cobalt, etc.) induces energy through a coil, and each individual guided pass of the magnet can be identified. Alternatively, this basic idea also includes applying compression to a piezoelectric element, also arranged on the device, via a pressure-generating element arranged on the device when the device is actuated. This piezoelectric element thus generates a voltage, and each individual voltage generation is identified. These actions increment a counter by 1. Each current counter reading can then be read at any time via an RFID / NFC peripheral device (e.g., a smartphone), for example, a combination of a chip and core plus a coil, which describes the current structural form of the RFID / NFC chip.

[0013] In any case, the device, in the form of a structural assembly “with an integrated coil for manipulating a cycle counter to identify motion via magnets,” is enclosed in a housing (e.g., made of glass, ceramic, sprayed into a plastic part, integrated into a plastic part, etc.), which protects the internal electronics from the handling medium and temperature. Data reading is achieved via an additional or external device with a corresponding receiving device (e.g., a smartphone, smart tray, tablet, etc.). The read data can be written to an external data storage device (e.g., cloud service, database, etc.). The solution according to the invention is adaptable and scalable to all objects, products, and / or instruments having specific two parts.

[0014] It should be understood that, depending on the shape of the corresponding instrument and / or the application of the instrument, a combination consisting of a magnet, a coil, a pressure generating element and a piezoelectric element with corresponding signal conversion can be conceived, and if possible, individual elements among the above elements can be omitted, as long as a countable signal suitable for counting each operating cycle is ultimately generated.

[0015] It should also be understood that the present invention is by no means limited to the medical field and the products, systems and / or devices used therein, but configurations and modifications that are conceivable and illustrated for a wide range of other products and / or other products.

[0016] Specifically, the task is accomplished by a device for detecting the manipulation cycle of a hand-operated instrument having at least a first movable part and a second movable part, wherein, in the manipulation cycle, the first movable part and the second movable part are capable of moving relative to each other. The device includes an energy detection coil disposed on one of a first movable member and a second movable member, and arranged to detect induced energy; an energy generating magnet disposed on the other of the first movable member and the second movable member, and arranged to inducedly generate energy to be detected by the energy detection coil, wherein the energy generating magnet and the energy detection coil are arranged such that, when the first movable member and the second movable member move relative to each other, the energy generating magnet can move relative to the energy detection coil within the detection area of ​​the energy detection coil and can be induced by the energy detection coil; and a storage and processing device having a counter and arranged to detect a voltage signal based on the energy induced in the energy detection coil during each relative movement, and to increment the counter by one each time the voltage signal is detected, thereby counting the number of manipulation cycles performed by the device.

[0017] In a particular embodiment, no energy is supplied to the device; that is, the device is constructed to be self-sufficient, powered by an external energy source (having an internal energy conversion device). In other words, the device is not powered by an external energy source. In other words, the device is powered solely by its internal energy conversion device. In other words, the device has no physical connection, especially no cable to an external energy source, i.e., located outside the device.

[0018] In another particular embodiment, energy can be supplied to the device in a hybrid manner through an internal smoothing buffer module with charging electronics and through hand manipulation of two parts movable relative to each other. That is to say, the smoothing buffer module and the hand manipulation can function as internal energy sources.

[0019] In an alternative implementation, the device can be powered simply by manual manipulation of two movable parts relative to each other.

[0020] Preferably, a magnetic core is arranged in the device and an energy detection coil is wound around the magnetic core. The magnetic core, together with the coil disposed thereon, is used in conjunction with a corresponding chip or combined structural element, particularly for providing RFID / NFC functionality. By directly winding the energy detection coil around the magnetic core, a separate energy detection coil can be advantageously eliminated.

[0021] Preferably, a magnetic core is arranged in the device, the energy detection coil is arranged separately from the magnetic core, and the magnetic core has an additional coil wound thereon. The dedicated coil on the magnetic core and for detection advantageously increases the degree of freedom in coordinating the device according to the respective application settings.

[0022] Preferably, the energy-generating magnet is a neodymium or samarium-cobalt magnet and is surrounded by a shield, such that the magnetic field of the energy-generating magnet points towards the energy detection coil in the direction of action and weakens in a direction different from that direction of action. This advantageously achieves only one predetermined direction of action.

[0023] Preferably, the energy-generating magnet can be inserted into the energy-detecting coil and induce energy in the coil through linear motion. This arrangement is advantageous in certain applications.

[0024] Preferably, an energy-generating magnet, which can be inserted into an energy detection coil, is arranged on a vibrating arm and can be brought into vibration by a body mechanically loaded onto the vibrating arm. Advantageously, in this way, the energy-generating magnet can generate energy for an extended period.

[0025] Preferably, the energy-generating magnet is rotatably arranged in the energy detection coil and induces energy in the coil through rotational motion. Furthermore, a speed-changing transmission mechanism may be arranged for speed adaptation of the rotational motion, and / or a flywheel mass may be arranged to support the maintenance of the rotational motion.

[0026] Alternatively, this task can be specifically addressed by a device for detecting the operation cycle of a hand-operated instrument, the device having at least a first movable part and a second movable part, wherein, in the operation cycle, the first movable part and the second movable part are movable relative to each other. The device includes a piezoelectric element disposed on one of the first movable part and the second movable part, and the piezoelectric element is arranged to be loaded with compression, stretching, and / or torsion, thereby establishing a voltage; electronic circuitry for operating the piezoelectric element; a pressure generating element disposed on the other of the first movable part and the second movable part, and the pressure generating element is arranged to load the piezoelectric element with compression, stretching, and / or torsion; and an energy detection coil arranged to convert the voltage established by the piezoelectric element into a detectable voltage signal, wherein the piezoelectric element and The pressure generating element is arranged such that, during relative movement of the first movable member and the second movable member, the pressure generating element applies compression, tension, and / or torsion to the piezoelectric element, and the voltage thereby established by the piezoelectric element is applied to the energy detection coil and a detectable voltage signal is generated therein; and a storage and processing device having a counter and arranged to detect the voltage signal generated in the energy detection coil during each relative movement, and to increment the counter by one each time the voltage signal is detected, thereby counting the number of manipulation cycles performed by the device.

[0027] Preferably, a magnetic core with a coil wound around it is also arranged in this alternative device. The magnetic core, together with the coil provided thereon, is used in conjunction with a corresponding chip or combined structural element, particularly to provide RFID / NFC functionality. By directly winding the energy detection coil onto the magnetic core, a separate energy detection coil can be advantageously omitted. However, the energy detection coil can also be arranged separately from the magnetic core, with the magnetic core having a separate coil wound around it. The dedicated coil on the magnetic core and for detection advantageously increases the flexibility in coordinating the device according to the separately configured applications.

[0028] Preferably, the storage and processing device has an EEPROM and an integrated circuit or is configured as a combined structural element, and provides an externally responsive and / or readable RFID / NFC device in combination with a magnetic core and a coil wound on the magnetic core.

[0029] Preferably, the device includes a smoothing buffer module with charging electronics, wherein the smoothing buffer module has capacitors, power capacitors, and / or batteries and is provided to support the storage and processing device. Advantageously, this allows the structural assembly to be expanded with additional smoothing buffer modules (capacitors, power capacitors, batteries, etc.) with charging electronics, so as to allow, for example, chips or combined structural elements to remain receptive for a longer period.

[0030] Preferably, the rotary hinge connecting the first movable part and the second movable part is at least partially composed of a piezoelectric element arranged to supply energy to the device by means of compression and torsion.

[0031] Preferably, the piezoelectric element is constructed in the form of a housing and arranged to tightly enclose other components of the device and to induce energy in the device when subjected to vibration, shock or compression. Attached Figure Description

[0045] In the accompanying drawings, the same reference numerals denote the same or at least equivalent parts and components. In this regard, redundant descriptions of these parts and components are appropriately omitted. Detailed Implementation

[0046] A preferred embodiment of a device (hereinafter also referred to as a maneuver cycle counter) for detecting, counting, and / or recording manually operated operating cycles of a product or instrument that is not powered by energy will now be described with reference to the accompanying drawings.

[0047] Figure 1 A schematic diagram of an apparatus for detecting the operation cycle of a hand-operated instrument, or operation cycle counter 100, according to a first embodiment, is shown.

[0048] according to Figure 1 The manipulated cycle counter 100 includes a storage and processing device 1, which can be provided in the form of EEPROMS, an IC with integrated circuit devices, a chip, or a combination of one or more of the above-mentioned elements, and is generally arranged to store and process data, values, signals, etc., detected, processed, or otherwise provided in the manipulated cycle counter. Furthermore, the manipulated cycle counter 100 includes a magnetic core 2 having a coil arrangement or coil 3 directly wound thereon. The coil 3 is connected at its two ends to corresponding input terminals on the storage and processing device 1. Additionally, the manipulated cycle counter 100 has an energy detection coil 4 for providing a signal, such as a voltage signal, which, in order to realize the counting function in the storage and processing device 1, is also connected at its ends to corresponding input terminals of the storage and processing device 1. In a first embodiment, the energy detection coil 4 is arranged separately from the coil 3 of the magnetic core 2. A sealed housing 6 surrounds the aforementioned components or structural groups 2 to 4 of the manipulated cycle counter 100.

[0049] Furthermore, the manipulation cycle counter 100 includes an energy-generating magnet 5, which can be movably positioned outside the housing 6 relative to the energy detection coil 4 and can be made of, for example, neodymium (iron boron), samarium cobalt, etc. To maintain the magnetic field pointing towards the coil and not affect other areas containing the energy detection magnet 5, the energy detection magnet 5 is surrounded by a shield, which will also be described. Therefore, only one direction of operation is achieved.

[0050] In other words, the operating cycle counter 100 has an energy detection coil 4 and an energy generating magnet 5. The energy detection coil is arranged on one of the first and second movable parts of the product or device, which are at least two parts, and is arranged to detect induced energy. The energy generating magnet is arranged on the other of the first and second movable parts of the product or device, which are at least two parts, and is arranged to inducedly generate energy to be detected by the energy detection coil 4.

[0051] That is, the components of the operating cycle counter 100, including components 1 to 4 and housing 6, are arranged on one of the first movable component and the second movable component, and the energy generating magnet 5 is arranged on the other of the first movable component and the second movable component. The energy generating magnet 5 and the energy detection coil 4 are arranged such that when the first movable component and the second movable component move relative to each other, the energy generating magnet 5 moves relative to and / or moves through the energy detection coil 4 within the detection area of ​​the energy detection coil 4, and hereby induces energy in the energy detection coil via the energy detection coil 4. This (linear) relative motion in... Figure 1 The image shows an energy-generating magnet 5, indicated by dashed lines along double arrows at different positions, and voltage arrows pointing towards the energy detection coil 4 at different positions. It should be understood that relative motion is not limited to linear motion, and other relative motions are also suitable for generating the desired energy in the energy detection coil 4.

[0052] The storage and processing device 1 includes a counter (not shown) and is arranged to detect a voltage signal based on the energy induced in the energy detection coil 4 during each relative movement, and increment the counter by one (1) each time a voltage signal is detected, thereby counting the number of manipulation cycles performed by the device.

[0053] The manipulation cycle counter 100, which has an integrated energy detection coil 4 for recognizing the movement of the energy-generating magnet 5, can be adapted and extended to objects, products, instruments, etc., as long as these objects, products, instruments, etc. have two parts, namely, at least a first movable part and a second movable part that can move relative to each other.

[0054] Figure 2A schematic diagram of a device for detecting the manipulation cycle of a hand-operated instrument according to a second embodiment is shown.

[0055] According to Figure 1 In the device of the first embodiment shown, the magnetic core 2 is equipped with a coil 3 dedicated to the magnetic core, and the energy detection coil 4 is arranged separately from the magnetic core 2. Figure 2 In the second embodiment shown, the energy detection coil is directly wound around the magnetic core 2.

[0056] The magnetic core 2, together with the coil disposed thereon, is used in conjunction with the corresponding chip or combined structural element to provide RFID / NFC functionality. By directly winding the energy detection coil onto the magnetic core, a separate energy detection coil 4 can be advantageously omitted. In other words, in the second embodiment, the function of the separate energy detection coil 4 is shared by the coil 3 of the magnetic core 2.

[0057] Manipulating the loop counter 100 in Figure 2 The remaining components and operating methods of the second embodiment shown correspond to the manipulation of the cycle counter 100 in... Figure 1 The components and operation of the first embodiment are shown in the figure, thereby allowing redundant descriptions associated with it to be appropriately omitted.

[0058] Preferably, the energy-generating magnet is a neodymium or samarium-cobalt magnet and is surrounded by a shield, such that the magnetic field of the energy-generating magnet points towards the energy detection coil in the direction of action and weakens in a direction different from that direction of action. This advantageously achieves only one predetermined direction of action.

[0059] Figure 3 A schematic diagram of a device for detecting the operation cycle of a hand-operated instrument according to a third embodiment is shown, and Figure 4 A schematic diagram of a device for detecting the manipulation cycle of a hand-operated instrument according to a fourth embodiment is shown.

[0060] The third and fourth embodiments correspond structurally and operationally to the first and second embodiments described above, respectively. The difference lies in the addition of a smoothing buffer module 7 (which may include a capacitor, such as a capacitor used in variant schemes, a power capacitor, a battery, etc.) with charging electronics (not shown) to allow the storage and processing device (chip) 1 to remain "receiveable" for a longer period. The smoothing buffer module 7 thus forms an additional energy storage device. In this case, the energy detection coil 3 can also be configured as an induction coil capable of inducing (wireless) power to the smoothing buffer module 7. The required energy input can, for example, be provided by an inductive charger on an operating table.

[0061] Figure 5A schematic diagram of an energy-detecting magnet 5 surrounded by a shield is shown. In embodiments of the manipulated cycle counter 100, the energy-detecting magnet can be used as an energy-generating magnet 5. To maintain the magnetic field pointing towards the energy-detecting coil and without affecting other areas of the energy-generating magnet 5, the energy-generating magnet 5 is surrounded by a shield 8 such that only one direction of action is achieved.

[0062] Figure 6 A schematic diagram of a device for detecting the manipulation cycle of a hand-operated instrument according to a fifth embodiment is shown.

[0063] The fifth embodiment is the same as the first embodiment in structure and operation, except that the energy detection coil 4 is arranged such that the energy generating magnet introduced into the energy detection coil 5 senses energy through the linear (reciprocating) motion in the energy detection coil 4.

[0064] Figure 7 A schematic diagram of a device for detecting the manipulation cycle of a hand-operated instrument according to a sixth embodiment is shown.

[0065] The sixth embodiment corresponds to the first embodiment in structure and operation, except that the energy detection coil 4 is configured such that the energy generating magnet 5, rotatably arranged in the energy detection coil 4, senses energy through rotational motion. Furthermore, to accommodate higher speeds, a transmission mechanism (not shown) for higher speeds can be arranged.

[0066] Figure 8 A schematic diagram of a device for detecting the operation cycle of a hand-operated instrument according to a seventh embodiment is shown. The seventh embodiment corresponds to the aforementioned sixth embodiment in structure and operation, except that in this modified seventh embodiment, an additional flywheel mass 9, such as a flywheel, can be arranged to maintain the rotational motion of the energy-generating magnet 5 for a longer period of time.

[0067] Figure 9 A schematic diagram of an apparatus for detecting the manipulation cycle of a hand-operated instrument according to an eighth embodiment is shown. In the eighth embodiment, in another configuration, the energy detection coil 4 is arranged such that the energy detection magnet 5 arranged in the energy detection coil 4 on the vibrating arm 10 can generate energy prolongably by loading the vibrating arm 10, that is, by the vibrating body 11 being in vibration, and thereby the body can be constructed, for example, in the form of a pin-shaped manipulation element.

[0068] Figure 10 A schematic diagram of a device for detecting the operation cycle of a hand-operated instrument is shown in an alternative embodiment according to the ninth embodiment.

[0069] According to Figure 10In an alternative embodiment, a piezoelectric element or piezoelectric element 12 is used instead of the energy generating magnet 5 and the counting device as an energy harvesting device. This piezoelectric element or piezoelectric element establishes (electro)voltage whenever it is loaded by the pressure generating element 13 with compression, tension, and / or torsion. Similarly, this piezoelectric element or piezoelectric element can establish (electro)voltage through vibration and impact. Therefore, (electro)voltage is generated by the relative movement of the first movable part and the second movable part when the (at least two-piece) device is closed, through compression, tension, or torsion.

[0070] As in Figure 10 As simplified in the lower part, the piezoelectric element 12 can be arranged, for example, in the region of a rotary joint of an instrument (e.g., scissors) having two parts that can move relative to each other, on one of the two parts that can move relative to each other, for example, embedded in one of the legs of the scissors, and the pressure generating element 13 can be arranged on the other part of the two parts that can move relative to each other, for example, embedded in the other leg of the scissors. When the scissors are closed, the pressure generating element 13 presses against the piezoelectric element 12, and the piezoelectric element then generates a voltage. This voltage is detected in the energy detection coil 4 and converted into a signal that can be measured or further processed by the storage and processing device 1 and ultimately counted.

[0071] In another modification, such a rotating hinge may, for example, consist at least partially or entirely of a piezoelectric element 12, which thereby supplies energy to the device due to compression and torsion.

[0072] The piezoelectric element 12 must be operated by a suitable electrical or electronic circuit device 14 for energy domination or energy management. This circuit device 14... Figure 11 The circuit is schematically shown and is necessary to prevent energizing of the piezoelectric element 12 through the smoothing and buffering module 7 (e.g., through a capacitor included in the smoothing and buffering module as a variant scheme). Similarly, the circuit arrangement 14 enables the charging of such a capacitor.

[0073] Figure 12 A schematic diagram of an apparatus for detecting the operation cycle of a hand-operated instrument according to the tenth embodiment is shown;

[0074] according to Figure 12 In another modification, the piezoelectric element 12 is constructed as a housing that sealably surrounds the device or structural assembly that serves as the housing, and when subjected to external vibration, impact, or compression, the piezoelectric element senses energy into the structural assembly.

[0075] As described above, in the apparatus for detecting the operation cycle of a hand-operated instrument in an operation cycle, a first movable part and a second movable part of the instrument can move relative to each other. An energy detection coil on one of the first and second movable parts detects induced energy. An energy generating magnet on the other of the first and second movable parts inductively generates energy to be detected by the energy detection coil. When the first and second movable parts move relative to each other, the energy generating magnet is movable relative to the energy detection coil within the detection area of ​​the energy detection coil and induces energy in the energy detection coil. The storage and processing device has a counter that detects a voltage signal based on the induced energy each time relative movement is performed, increments the counter by one each time a voltage signal is detected, and thereby counts the number of operation cycles performed by the instrument. In an alternative embodiment, a voltage signal is generated using a voltage established by a piezoelectric element.
