Apparatus for detecting activation cycles of manually operated equipment - Patents.com

Abstract

The present invention relates to an apparatus for detecting activation cycles of a manually operated instrument, wherein first and second movable parts of the instrument are movable relative to one another during an activation cycle. An energy detection coil disposed on one of the first and second movable parts detects inductively generated energy. An energy-generating magnet disposed on the other of the first and second movable parts inductively generates energy that is detected by the energy detection coil. As the first and second movable parts move relative to one another, the energy-generating magnet is movable within a detection range of the energy detection coil, inducing energy within that range. The storage and processing device has a counter that detects a voltage signal based on the induced energy during each relative movement, and increments the counter by one each time a voltage signal is detected, thereby counting the number of activation cycles performed by the instrument. In an alternative embodiment, the voltage signal is generated using a voltage generated by a piezoelectric element.

Description

[Technical field]

[0001] The present invention relates to an apparatus and system for detecting activation cycles of manually operated instruments, and in particular to an apparatus and system for detecting, counting and / or documenting activation cycles of instruments in the medical field such as scissors, forceps, punches, laparoscopic instruments, etc., and providing relevant information derived therefrom for further processing. [Background technology]

[0002] Until now, it has not been possible to detect and document in electronic and / or digital form the activation cycles of manually operated unpowered equipment in the medical field and further process the associated findings thereon.

[0003] Due to unavailable information such as activation cycles, it is also not possible, at least in part, to generate automated reports regarding the general condition of a manually operated product or equipment, its expected useful life or the end of its useful life that it has already reached, its performance and suitability for subsequent operation (as described, for example, in a purpose report), and / or any overloads present and any damage that has occurred.

[0004] Up to now, it has been necessary to carry out tests and visual inspections for this purpose, which are time-consuming and costly, and which, due to the lack of detected data, are subject to various evaluations on a case-by-case basis. This can lead to the application of a safety margin leading to the disposal of products and equipment as a precaution (i.e. too early), even though they could have been used for a longer period if they had been detected and thus evaluated on the basis of solid use data. This in turn leads to increased procurement efforts and associated costs, and to the disposal of more material than would have been possible according to actual use conditions.

[0005] Furthermore, the lack of corresponding data makes it impossible to create customized services and tailored business models for customers, which are also suboptimal in terms of procurement and business costs for customers.

[0006] In addition, issues regarding, for example, service life, as well as reasons and evidence in the event of a complaint, are becoming increasingly important. Furthermore, the German patent translation DE 698 13 533 T2, the German utility model DE 20 2012 012 758 U1, the German utility model DE 20 2013 100 949 U1 and the German patent translation DE 694 35 028 T2 are known from the prior art. Summary of the Invention

[0007] The object of the invention is to provide an apparatus and system for detecting the activation cycle of a manually operated unpowered product or device in the medical field, which allows a user or customer to directly detect the number of times the unpowered product or device has been used, i.e. to count the number of times it has already been operated and to recognize whether the product or device is still able to perform the required function.

[0008] According to the invention, this object is achieved by an arrangement having the features of claim 1 and alternatively by an arrangement having the features of claim 12. Advantageous further embodiments of the invention are the subject matter of the attached dependent claims.

[0009] The number of activation cycles is generally a measure proportional to, among other things, the general condition of the device, its useful life or end of useful life, its performance and suitability for upcoming operation (as detailed in the intended purpose), as well as overloading of the device and any damage that may have occurred to the product. Another measure may be the reprocessing cycle of the device, which may be determined in cooperation with a suitable data acquisition system, such as via a readable data memory like an RFID chip, NFC and BLE, etc.

[0010] The invention is based on the general idea of ​​providing a device that acts as an activation cycle counter for detecting activation cycles of an unpowered, manually operated medical device.

[0011] The aforementioned activation cycle counter is arranged to count the activations of the device and, in cooperation with the RFID / NFC / BLE module, provide a means to indicate the remaining useful life of the device. Detection is based on a sensor device that operates without an external power supply, whereby a detectable or countable and further processed activation signal is generated from the hand movements of a user, e.g. a surgeon, during use of the device.

[0012] The basic idea is that a passing magnet (neodymium-iron-boron, samarium-cobalt, etc.) is energized through a coil and each passing magnet is detected. Alternatively, the basic idea involves applying pressure via a pressure generating element located on the device against a piezo element also located on the device, which generates a voltage, and detecting each time the device is activated. Each such movement increments a value in a counter by one. The current reading of each counter can then be read at any time via an RFID / NFC peripheral device (such as a smartphone) using, for example, a chip-core-plus-coil combination representative of current designs of RFID / NFC chips.

[0013] In all cases, the device in the form of an assembly group of "activation cycle counter with integrated coil for motion detection via magnet" is enclosed in a closed housing (e.g. made of glass, ceramic, plastic part injection, one piece of plastic part, etc.) which protects the internal electronics from process media and temperature. The reading of the data is done via an additional or external device with a corresponding receiving device (e.g. smartphone, smart tray, tablet, etc.). The read data can be written to an external data memory (e.g. cloud service, database, etc.). The solution according to the invention is transferable and scalable to all items, products and / or equipment with a certain two-part structure.

[0014] It will be understood that depending on the respective device geometry and / or device application, combinations of magnets, coils, pressure generating elements and corresponding signal converting piezo elements, as well as individual omissions of the aforementioned elements where appropriate, are conceivable as long as a countable signal suitable for counting each activation cycle is ultimately generated.

[0015] Furthermore, it is understood that the present invention is in no way limited to the medical field and products, systems and / or equipment used in the medical field, but that correspondingly modified configurations and modifications for many further and / or other products are conceivable and expressible.

[0016] In particular, the object is solved by a device for detecting activation cycles of a manually operated device having at least first and second movable parts, the first and second movable parts being movable relative to each other during an activation cycle, the device comprising: an energy detection coil arranged on one of the first and second movable parts and arranged to detect inductively generated energy, an energy generating magnet arranged on the other of the first and second movable parts and arranged to inductively generate energy that is detected by the energy detection coil, the energy generating magnet and the energy detection coil being arranged such that, due to relative movement of the first and second movable parts with each other, the energy generating magnet is relatively movable within a detection range of the energy detection coil and induces energy via the energy detection coil within said range, and a memory and processing unit having a counter arranged to detect, at each relative movement, a voltage signal based on the energy induced in the energy detection coil and to increment the counter by one for each detection of the voltage signal, thereby counting the number of performed activation cycles of the device.

[0017] In a special embodiment, the device is not powered, i.e. it is designed as an autonomous device with respect to an external energy source (and an internal energy converter). In other words, inter alia, the device is not powered by an external energy source. In other words, the device is exclusively powered via an internal energy converter. In other words, the device has no physical connection, in particular no cable, to an external energy source, i.e. outside the device.

[0018] In another particular embodiment, the device may be powered by a mixed method of both an internal smoothing buffer module with charging electronics and manual actuation of two relatively movable parts, i.e. the smoothing buffer module and manual actuation may act as an internal energy source.

[0019] In an alternative embodiment, the device may be powered solely by manual actuation of two relatively movable parts.

[0020] Preferably, a magnetic core is disposed within the device and the energy detection coil is wound around the magnetic core. The magnetic core and associated coil are used in conjunction with a corresponding chip or combined components to provide, among other things, RFID / NFC functionality. By winding the energy detection coil around the magnetic core, a separate energy detection coil can be advantageously omitted.

[0021] Preferably, a magnetic core is disposed within the device and the energy detection coil is disposed separately from the magnetic core, the magnetic core having a further coil wound thereon. A dedicated coil on the magnetic core and for detection advantageously increases the flexibility in adapting the device to a particular intended application.

[0022] Preferably, the energy-generating magnet is a neodymium or samarium-cobalt magnet and is surrounded by a shield such that the magnetic field points in an effective direction towards the energy-detecting coil and is attenuated in other than the effective direction. Advantageously, only one predeterminable effective direction is obtained.

[0023] Preferably, the energy-generating magnet is insertable into the energy-detecting coil and induces energy by linear movement within the energy-detecting coil, such an arrangement being advantageous in certain applications.

[0024] Preferably, the energy-generating magnet, insertable into the energy-detecting coil, is arranged on a pivot arm and can be vibrated by a body mechanically moving on the pivot arm. Advantageously, in this way the energy-generating magnet can generate extended energy.

[0025] Preferably, the energy generating magnet is rotatably disposed within the energy detection coil to induce energy by rotational movement within the energy detection coil, and further, a transmission gear may be disposed to adjust the rotational speed of the rotational movement and / or a flywheel mass may be disposed to assist in sustaining the rotational movement.

[0026] Alternatively, the object is solved in particular by an apparatus for detecting the activation cycle of a manually operated instrument having at least first and second movable parts, the first and second movable parts being movable relative to each other during the activation cycle. The device comprises: a piezoelectric element disposed on one of the first and second movable parts and arranged to be subjected to pressure, tension, and / or torsion and thereby generate a voltage; an electrical circuit assembly for operating the piezoelectric element; a pressure generating element disposed on the other of the first and second movable parts and arranged to subject the piezoelectric element to pressure, tension, and / or torsion; and an energy detection coil arranged to convert the voltage generated by the piezoelectric element into a detectable voltage signal, wherein the piezoelectric element and the pressure generating element are disposed such that relative movement of the first and second movable parts to each other causes the pressure generating element to apply pressure, tension, and / or torsion to the piezoelectric element, whereby the voltage generated by the piezoelectric element is applied to the energy detection coil, thereby generating a detectable voltage signal; and a memory and processing unit comprising a counter arranged to detect the voltage signal generated in the energy detection coil at each relative movement and to increment the counter by one for each detection of a voltage signal, thereby counting the number of activation cycles performed of the device.

[0027] Preferably, a magnetic core is also disposed in this alternative device, the magnetic core having a coil wound thereon. The magnetic core and associated coil work in conjunction with a corresponding chip or combined components to provide, among other things, RFID / NFC functionality. By winding the energy detection coil directly on the magnetic core, a separate energy detection coil can be advantageously omitted. However, the energy detection coil may be disposed separately from the magnetic core, and the magnetic core may have other coils wound on it. The magnetic core and a dedicated coil for detection advantageously increase the flexibility in adapting the device to a particular intended application.

[0028] Preferably, the storage and processing unit comprises an EEPROM and integral circuit or is formed as a combined component, and in combination with the magnetic core and a coil wound on the magnetic core provides an RFID / NFC device with externally addressable and / or readable RFID / NFC functionality.

[0029] Preferably, the device includes a smoothing buffer module with charging electronics, the smoothing buffer module comprising a capacitor, a PowerCap and / or a battery, arranged to support the storage and processing unit. Advantageously, the assembly population is extended by additional smoothing buffer modules with charging electronics (capacitors, PowerCap, batteries etc.) for example to keep the chip or combination part receptive for a longer period of time.

[0030] Preferably, the pivot joint connecting the first and second movable parts consists at least in part of a piezoelectric element arranged to energise the device via pressure and torsion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0033] In the drawings, identical reference numerals denote identical or at least equivalent parts and components, and in this respect redundant and repeated descriptions of such parts and components are omitted for convenience.

[0034] A preferred embodiment of an apparatus for detecting, counting and / or documenting activation cycles of a manually operated unpowered product or equipment as detailed herein (hereinafter also referred to as an activation cycle counter) is described below with reference to the accompanying drawings.

[0035] FIG. 1 shows a schematic diagram of an apparatus for detecting activation cycles of a manually operated device, namely an activation cycle counter 100, according to a first exemplary configuration.

[0036] According to FIG. 1, the activation cycle counter 100 includes a storage and processing device 1. The storage and processing device 1 may be provided in the form of an EEPROM, an IC with an integrated circuit assembly, a chip, or a combination part with one or more of the aforementioned elements, and may be arranged to generally store and process data, values, signals, etc., detected, processed, or otherwise provided to the activation cycle counter. Furthermore, the activation cycle counter 100 includes a magnetic core 2 and a coil assembly or coil 3 wound directly around the magnetic core 2. The coil 3 is connected at two respective ends to respective inputs of the storage and processing device 1. In addition, the activation cycle counter 100 includes an energy detection coil 4 providing a signal, for example a voltage signal, which is also connected at its ends to corresponding inputs of the storage and processing device 1 in order to perform the counting function in the storage and processing device 1. In a first configuration example, the energy detection coil 4 is arranged separately from the coil 3 and the magnetic core 2. A tightly sealed housing 6 surrounds the aforementioned parts or assembly groups 2-4 of the activation cycle counter 100.

[0037] Additionally, the activation cycle counter 100 includes an energy-generating magnet 5 external to the housing 6 that is movable relative to the energy-sensing coil 4 and may be made of, for example, neodymium (iron-boron), samarium-cobalt, etc. To keep the magnetic field pointed toward the coil and not affect other areas of the energy-generating magnet 5, the energy-sensing magnet 5 is surrounded by a shield, as described below, so that only one effective orientation is provided.

[0038] In other words, the activation cycle counter 100 comprises an energy detection coil 4 disposed in at least one of the first and second movable parts of the at least two-part product or device and arranged to detect inductively generated energy, and an energy generating magnet 5 disposed in the other of the first and second movable parts of the at least two-part product or device and arranged to inductively generate energy that is detected by the energy detection coil 4.

[0039] That is, the portion of the activation cycle counter 100 comprising the components 1-4 and the housing 6 is arranged on one of the first and second movable parts, and the energy generating magnet 5 is arranged on the other of the first and second movable parts. The energy generating magnet 5 and the energy detecting coil 4 are arranged such that when the first and second movable parts move relative to each other, the energy generating magnet 5 is movable relative to and / or through the latter within a detection range of the energy detecting coil 4, and during processing induces energy in and through the energy detecting coil 4. This (here linear) relative movement is illustrated in FIG. 1 with the energy generating magnet 5 shown in dashed lines at various positions along the double arrow and with voltage arrow symbols directed relative to the energy detecting coil 4 at various positions. It will be understood that the relative movement is not limited to linear movement and other relative movements are also suitable to generate the desired energy in the energy detecting coil 4.

[0040] The storage and processing unit 1 comprises a counter (not shown) and is arranged to detect a voltage signal based on the energy induced in the energy detection coil 4 by each relative movement and to increment the counter by one for each detection of a voltage signal, thereby counting the number of activation cycles performed of the device.

[0041] The activation cycle counter 100 with an integrated energy detection coil 4 that detects movement via an energy generating magnet 5 is transferable and expandable to items, products, equipment, etc., provided the items, products, equipment, etc. have a specific two-part structure, i.e., a first movable part and a second movable part that are movable relative to each other.

[0042] FIG. 2 shows a second configuration example of an apparatus for detecting an activation cycle of a manually operated device. 100 A schematic diagram of the above is shown.

[0043] The apparatus according to the first configuration example shown in FIG. 100 In the previous example, the magnetic core 2 was arranged with a dedicated coil 3, and the energy detection coil 4 was arranged separately from the magnetic core 2, whereas in the second configuration example shown in FIG. 2, the energy detection coil is wound directly around the magnetic core 2.

[0044] The magnetic core 2 with its associated coil is used in conjunction with a corresponding chip or combination component that provides, inter alia, RFID / NFC functionality. By winding the energy detection coil directly on the magnetic core, the separate energy detection coil 4 can advantageously be omitted. In other words, the function of the separate energy detection coil 4 in the second configuration example is taken over by the coil 3 of the magnetic core 2.

[0045] Other components and operating modes of the second configuration example of the activation cycle counter 100 shown in FIG. 2 correspond to the components and operating modes of the first configuration example of the activation cycle counter 100 shown in FIG. 1, and redundant explanations in this respect can be omitted for convenience.

[0046] Preferably, the energy-generating magnet is a neodymium or samarium-cobalt magnet surrounded by a shield such that the magnetic field points in an effective direction towards the energy-detecting coil and is attenuated in other than the effective direction. Advantageously, only one predeterminable effective direction is obtained.

[0047] FIG. 3 shows a device for detecting the activation cycle of a manually operated device according to a third configuration example. 100 FIG. 4 shows a schematic representation of an apparatus for detecting activation cycles of a manually operated device according to a fourth configuration example. 100 A schematic diagram of the above is shown.

[0048] The third and fourth configuration examples correspond in structure and operation to the first and second preceding configuration examples, respectively, except that a smoothing buffer module 7 (which may include a capacitor, e.g. a capacitor acting as a distribution, powercap, battery, etc.) is additionally arranged with charging electronics (not shown) for keeping the storage and processing device (chip) 1 "ready to receive" for a longer period of time. The smoothing buffer module 7 thus forms an additional energy store. In this context, the energy detection coil 3 may be designed as an induction coil allowing inductive (wireless) energization of the smoothing buffer module 7. The required energy input may be provided, for example, by an inductive charger on the operating table.

[0049] 5 shows a schematic diagram of an energy generating magnet 5 surrounded by a shield that can be used as the energy generating magnet 5 in an example implementation of the activation cycle counter 100. The energy generating magnet 5 is surrounded by a shield 8 to provide only one effective direction to keep the magnetic field pointed toward the energy detection coils and not affect other areas of the energy generating magnet 5.

[0050] FIG. 6 shows a fifth configuration example of an apparatus for detecting an activation cycle of a manually operated device. 100 A schematic diagram of the above is shown.

[0051] The fifth configuration example corresponds to the preceding first configuration example in structure and operation, except that the energy detection coil 4 is positioned such that an energy generating magnet inserted into the energy detection coil 4 induces energy by linear (back and forth) movement within the energy detection coil 4.

[0052] FIG. 7 shows a sixth configuration example of an apparatus for detecting an activation cycle of a manually operated device. 100 A schematic diagram of the above is shown.

[0053] The sixth configuration example corresponds to the preceding first configuration example in structure and operation, except that the energy detection coil 4 is arranged such that the energy generating magnet 5 rotatably arranged within the energy detection coil 4 induces energy by rotational movement. For adaptation to high speeds, a transmission gear (not shown) for high speeds can also be arranged.

[0054] FIG. 8 shows a seventh configuration example of an apparatus for detecting an activation cycle of a manually operated device. 100 The seventh configuration example corresponds to the preceding sixth configuration example in structure and operation, except that in this variant a flywheel mass 9, e.g. a flywheel, for sustaining the rotational operation of the energy-generating magnets 5 for a longer period of time may additionally be arranged.

[0055] FIG. 9 shows an eighth configuration example of a device for detecting an activation cycle of a manually operated device. 100 In an eighth configuration example, in a further design, an energy generating magnet 5 on a pivot arm 10 arranged in an energy detection coil 4 is vibrated by a body 11 acting on, i.e. actuating, the pivot arm 10. The body 11 can be, for example, a pin-type actuating element, which can generate energy in an extended form.

[0056] FIG. 10 illustrates an apparatus for detecting activation cycles of a manually operated device in an alternative embodiment according to a ninth configuration example. 100 A schematic diagram of the above is shown.

[0057] In an alternative embodiment according to Fig. 10, a piezoelectric or piezo element 12, which increases an (electrical) voltage when a pressure-generating element 13 applies pressure, tension and / or torsion, is used as energy generating and counting device instead of the energy-generating magnet 5. Similarly, it increases an (electrical) voltage by the action of vibration and shock. Thus, an (electrical) voltage is generated by pressure, tension or torsion when the (at least two-part) device is closed via the relative movement of its first and second movable parts.

[0058] As shown in simplified form in the lower part of Fig. 10, the piezo element 12 may be arranged, for example, in the region of a pivot joint of one of the two parts of a device (for example scissors) that has two parts that can be moved relative to each other, for example, integrated in one leg of the scissors, and the pressure-generating element 13 may be arranged in the other of the two parts that can be moved relative to each other, for example, integrated in the other leg of the scissors. When the scissors are closed, the pressure-generating element 13 presses against the piezo element 12, causing a voltage increase. This voltage is detected by the energy detection coil 4 and converted into a signal that can be measured or further processed, and finally counted by the storage and processing device 1.

[0059] In a further variant, for example, such a pivot joint may consist at least in part or in whole of a piezo element 12 which supplies pressure and torsion-induced energy to the device.

[0060] For energy management or energy control, the piezo element 12 must be operated with a suitable electric or electronic circuit assembly 14. This circuit assembly 14 is represented diagrammatically in Fig. 11 and is necessary to prevent the piezo element 12 from being energized by the smoothing buffer module 7 (for example by a capacitor acting as a distribution contained therein). This circuit assembly 14 likewise allows the charging of such a capacitor.

[0061] FIG. 12 shows a device for detecting the activation cycle of a manually operated device according to a tenth configuration example. 100 A schematic diagram of the above is shown.

[0062] According to FIG. 12, in a further variant, the piezo element 12 is 100 Or it may be formed as a housing that tightly encases the assembly mass and induces energy into the assembly mass when it is exposed to external vibration, shock or impact, or pressure.

[0063] As described above, a device for detecting the activation cycle of a manually operated device during the activation cycle 100 In the device, first and second movable parts of the device are movable relative to one another. An energy detection coil in one of the first and second movable parts detects inductively generated energy. An energy generating magnet in the other of the first and second movable parts inductively generates energy that is detected by the energy detection coil. The energy generating magnet is movable relative to the energy detection coil and induces energy in the energy detection coil when the first and second movable parts move relative to one another within a detection range of the energy detection coil. The storage and processing device includes a counter and detects a voltage signal based on the energy induced by each relative movement and increments the counter by one for each detection of the voltage signal, thereby counting the number of performed activation cycles of the device. In an alternative embodiment, the voltage signal is generated using a voltage multiplied by a piezoelectric element.

[0064] It is understood that the invention is not limited to the preceding construction examples, but that within the scope of protection defined in the claims, changes, modifications, combinations and equivalent arrangements are readily accessible to those skilled in the art.
