Description

Technical Field

[0001] This invention relates to a medical device having a transponder mounting module / transponder insertion module, wherein the transponder mounting module has a transponder adapted to receive and / or transmit electromagnetic waves, particularly data signals. Furthermore, this invention also relates to a medical transponder communication system / transponder system for communicating with, reading from, and / or writing to the transponder mounting module. Background Technology

[0002] Structures with transponders or (medical) tagging elements with RFID transponders or RFID tags are known from the prior art, and they are particularly used for mounting surgical instruments. Such instruments can be identified, tracked, and managed by means of RFID transponders attached to them. In particular, specific information about the instrument can be read.

[0003] For example, EP 3 193 284 A1 discloses a medical marking element for mounting surgical instruments, which can then be attached to the surgical instruments on the surface side. Here, the marking element has an annular metal frame with a non-conductive cover, and an RFID transponder / RFID tag is introduced into the cavity of the marking element. The outer side of the metal frame is attached to the surgical instruments at a predetermined location, particularly by welding.

[0004] Similarly, WO 2015 / 177 538 A1 discloses a box-shaped structure assembly with an RFID transponder, which can then be mounted on the surface side to the metal frame of a surgical instrument. The cover is here made of a material permeable to electromagnetic energy.

[0005] A drawback of existing technologies is that, due to the short (signal technology) transmission range of transponders, transponders, especially passive transponders, must be positioned at a small distance from the reading or reading / writing device. This is particularly relevant to NFC (Near Field Communication) RFID tags. For this reason, in common transponder / RFID tags, it is generally only possible to subsequently apply the RFID tag to an exposed and easily accessible outer surface of the medical device in order to keep the distance between the transponder and the reading device to a minimum. It is important to note that the outer surface is positioned in a device location that introduces only minor disadvantages in terms of device operation while still ensuring sufficient transmission quality or adequate reception.

[0006] Furthermore, the power of transmission, reception, or sending is decisively affected by the components or structure surrounding the transponder. This also relates to the (signal technology) reliability of the transponder's transmission. However, especially with changes in the maximum possible distance of the reading and / or writing devices, reading becomes no longer possible, or at least not entirely reliable, depending on the device's structure and the location of the RFID tag element. The geometric mounting of the RFID tag element, and therefore the RFID chip of the transponder, has a significant impact on this maximum distance and varies between devices, thus the tag elements according to the prior art cannot provide safe, reliable, and predictable operation.

[0007] Therefore, in the design and development of medical devices, the RFID tagging element and its surrounding environment must always be considered and incorporated into the design, as this ensures the existence of a suitable surrounding structure for the transponder. This makes the development of medical devices independent of the transponder difficult. Because the approval process for medical products is time-consuming and very expensive, this presents particularly high barriers and corresponding adaptation challenges for both existing and new medical products.

[0008] Besides signal technology issues, the existing technology also suffers from the following drawbacks. Although such RFID tagging elements are relatively small components, the subsequent application of tagging elements with RFID transponders in the existing technology creates additional adhesion surfaces for contaminants and further obstructs the operation of medical devices. Furthermore, surface-mounted RFID tagging elements can create gaps and cracks where bacteria can accumulate. Due to the design of the tagging elements and their placement on medical devices, irreversible installation, especially welding, is unavoidable, making necessary replacements difficult when the transponder is damaged or scheduled for replacement. Moreover, externally mounted tagging elements always pose a risk of tearing of surgical gloves and patients, as well as user injury, due to their sharp edges.

[0009] The manufacture and installation of RFID tag elements, especially those using welding, is extremely cumbersome and completely impossible in some medical devices due to the lack of suitable materials for welding or unsuitable mounting surfaces. In particular, the housing or support components of RFID tag elements must always be made of metal to allow for mounting and welding, limiting the available materials for the design. Furthermore, medical device approval regulations specifically require the reproducibility and ease of installation of RFID tag elements. Similarly, metal surfaces can shield RFID tag elements and reduce their accessibility. Summary of the Invention

[0010] Therefore, the object of this invention is to eliminate or at least reduce the disadvantages of the prior art and, in particular, to provide a medical device, especially a medical instrument, and a transponder communication system having a transponder mounting module, which ensures the reliability of signal communication and, particularly, improves the transponder's receiving or receiving power and / or transmitting power in terms of distance from reading and writing devices. Furthermore, the cleanability, sterilizability, and good and reliable operation of the medical instrument and the transponder mounting module should be improved. Similarly, the development, manufacture, installation, maintenance, repair, and replacement of the medical instrument and the transponder mounting module should be improved. The transponder mounting module should be able to be quickly replaced during maintenance.

[0011] In other words, the objective of this invention is particularly to provide a medical device that ensures good and reliable operation in terms of both device characteristics and transponder data transmission characteristics. A further objective is preferably the good cleanability and / or sterilizability of the medical device.

[0012] This task is solved according to the features of the invention in the case of medical devices of the type having a transponder mounting module, and also according to the features of the invention in the case of medical transponder communication systems of the type.

[0013] The core of this invention lies in improving transponder reception, and particularly improving the possible distance to external reading and / or writing devices, through a structurally and geometrically prefabricated, uniform transponder mounting module / transponder insertion module / container (with a accommodated and positioned transponder, especially in the form of a glass tag, and a baffle with predetermined geometric dimensions specifically arranged relative to the transponder) for transponder / transponder structure assemblies. The transponder mounting module is adapted by its housing to be inserted into a pre-prepared recess or opening in a medical device, especially a medical instrument, such that this independent unit of the transponder mounting module can be inserted not only into existing medical instruments but also into new medical instruments, and itself already meets the requirements for data communication through its predefined structure. The medical instrument itself only requires a predefined recess or opening for insertion.

[0014] The transponder mounting module, as a structural assembly, has a defined housing that positionally holds and supports the transponder, particularly a glass tag, and also positionally holds a baffle or reinforcing baffle relative to the transponder. The housing itself is particularly transmissive to signals and preferably has little or no influence on the transponder's (signal-technical) reception or electromagnetic interaction. The housing can be designed, particularly for good cleanability and sterilization, and also for mounting or inserting medical devices. In stark contrast, the baffle is made of or constructed of a material that is impermissive to signals or, at least for a defined frequency range, to electromagnetic waves. The baffle has a significant influence on the electromagnetic interaction between the transponder and the upper side of the transponder mounting module and is particularly designed and adapted to focus and / or amplify electromagnetic signals or waves between the upper side of the transponder mounting module and the transponder.

[0015] This structure allows the transponder mounting module to be optimally designed as a single unit, significantly improving the reception of transponders and the transmission to and from the transponder to the upper side. This also improves communication between transponder reading and / or writing devices in areas that can be positioned on the upper side or the surface of the instrument body, thereby ensuring secure and reliable reading and / or writing to the transponder over greater distances through the design of the transponder mounting module itself.

[0016] Specifically, the transponder mounting module therefore has a transponder, preferably an RFID transponder, also known as an RFID tag or RFID marker, and particularly preferably a glass transponder, also known as a glass tag. The transponder is configured and adapted for receiving and / or transmitting (electromagnetic) waves or signals. The transponder is therefore a contactless radio communication device that receives incoming signals and automatically responds or forwards them. The transponder can be either an active or passive transponder. Furthermore, the transponder mounting module has a housing / transponder bracket / transponder carrier having an upper side and a lower side opposite to the upper side. The housing is configured and constructed to positionally accommodate the transponder between the upper and lower sides and is also configured and constructed for insertion into or mounting into a pre-fabricated or pre-prepared recess, depression, cavity, or opening in the surface of the medical device, particularly the medical instrument (with its lower side pointing in the direction of the recess), such that the lower side of the medical instrument is retracted relative to the upper side of the transponder mounting module and particularly relative to the surface of the medical device, preferably the surface of the medical instrument's body.

[0017] For example, conventional or standardized longitudinal grooves with particularly rounded edges and / or ends can be used as pre-prepared recesses or openings for medical devices, especially medical instruments. The pre-prepared recesses or openings, in particular, have a recess direction perpendicular to the surface or instrument body surface at their location. For example, at a freely selectable location on the medical instrument, the pre-prepared recess or opening can be introduced perpendicular to the instrument body surface thereby using a milling tool, especially a keyway cutter, into which the transponder mounting module can then be inserted, particularly by means of press-fitting / press-fitting. This allows for press-fitting. In particular, the pre-prepared recess has a constant depth relative to the (instrument body) surface.

[0018] The transponder mounting module according to the invention has an electromagnetically (signal) impermeable baffle / reinforced baffle with a particularly centrally located baffle opening. The baffle is therefore made of a material that is impermeable to electromagnetic waves, particularly in the radio frequency and / or medium wave and / or short wave and / or ultra-short wave ranges. This can be, in particular, a highly conductive metallic material. Preferably, the baffle is made of metal or even entirely of metal, particularly stainless steel. Thus, the baffle forms a signal-impermeable frame for the baffle opening and shielding or reflective shielding, and only the baffle opening itself, with its specific geometry and dimensions, is configured to allow signals or electromagnetic waves to pass through.

[0019] Furthermore, the baffle is specifically arranged relative to the transponder. Specifically, the transponder is spaced apart from the baffle and retracts towards the lower side of the transponder mounting module. This arrangement allows the baffle to be positioned between the upper side and the transponder. The baffle opening specifically points towards the upper side and / or towards the transponder. In particular, the baffle is arranged such that the plane of the baffle opening is parallel to the upper side and / or perpendicular to the connecting line between the transponder and the upper side. In other words, preferably, when viewed from the upper side of the transponder mounting module towards the transponder, the baffle opening has its largest baffle opening area in its position.

[0020] Therefore, by inserting or mounting the transponder module into a pre-prepared recess or opening, the signal communication between the transponder on one side and an externally arranged or positioned read / write device on the other side is improved. Since the immediate surrounding environment of the transponder's structure is essentially predetermined by the transponder mounting module, which substantially affects transmission, no adaptation to the medical device is required in terms of the transponder's receiving capabilities.

[0021] In other words, the transponder mounting module is based on the fundamental idea that, when a housing capable of transmitting signals (often made of thermoplastic, thermosetting, general plastic, and / or silicone) is selected, the read and / or write distance is optimized by a geometrically defined opening through a metal shield / reflector / baffle with a baffle opening that at least partially surrounds the housing and thus the transponder, which spacees the transponder from the upper side and thus from the read and write devices that can be arranged there.

[0022] Transponder mounting modules can also be integrated into medical devices more effectively and flexibly. Medical devices require only standardized, pre-fabricated / pre-prepared recesses, openings, depressions, or cavities on or within the device body. In other words, the lower side, and the transponder itself, are positioned further / deeper towards the recess than the baffle and upper side of the transponder mounting module. In particular, the shape of the transponder mounting module allows for complete bottom insertion, ending flush with the device body surface or retracting inwards relative to the device body surface.

[0023] Transponder mounting modules can be used to detect, record, and further process product-related preparation cycles with relevant information. These preparation cycles may include, for example, cleaning and / or sterilization and / or oiling. Transponder mounting modules enable so-called tracking and life management of medical devices / products, especially medical instruments. This information is also used by manufacturers as evidence in complaint cases. Furthermore, users can perform maintenance on medical devices, especially medical instruments, equipped with transponder mounting modules only when individual maintenance is required, eliminating the need to adhere to predefined maintenance intervals. This improves the availability and supply of medical devices, as maintenance intervals can be extended individually.

[0024] In other words, information can be recorded within the medical device itself using the transponder mounting module according to the invention. This has the advantage of transparency in maintenance situations (where the transponder, especially a glass tag or the RFID chip of the glass tag carries this information), in runtime estimation, in tracking within business models (e.g., so-called pay-per-user usage), and in lifespan indications (MDR requirements, standard requirements), wherein the receptivity of the transponder of the transponder mounting module is improved when the transponder mounting module is inserted into the medical device.

[0025] Here, the state in which all components of the transponder mounting module are installed or assembled, and the transponder mounting module exists as a complete unit or structural assembly and can be loaded or inserted into a medical device, is referred to as the assembled state or the combined state.

[0026] Conversely, the loading or insertion state refers to a state in which the transponder mounting module (in the combined state) is loaded or inserted into a medical device, particularly a medical instrument, or more precisely, loaded or inserted into a pre-prepared recess or opening.

[0027] It is emphasized here that the transponder mounting module is an independent invention and is either independently claimable or separately claimable and should be the subject of a separate application.

[0028] Advantageous implementation methods are described below.

[0029] In particular, the transponder mounting module and, especially, the housing, can be configured and arranged to be inserted and / or removed or inserted and / or taken out without tools into pre-prepared recesses or openings in the medical device. More preferably, the housing of the transponder mounting module can be configured and adapted to form a press-fit in a pre-prepared recess or opening. In particular, at least one section of the sidewall or sidewall arranged between the upper and lower sides of the housing can be configured such that the sidewall induces an elastic preload or compression transverse to the connecting line between the upper and lower sides and / or parallel to the surface of the device body, so as to hold the transponder mounting module in its inserted state or position by means of a force-transmitting fit, especially a friction fit. This achieves a particularly simple and reversible installation or insertion into the medical device. Replacement of the entire assembly of the transponder mounting module is also particularly quick and simple. Furthermore, the medical device is not damaged during replacement. Replacement can also be performed particularly quickly.

[0030] Preferably, the transponder mounting module can be configured and arranged for tool-free assembly or combination. Components or parts of the transponder mounting module can be combined into insertable structural assemblies, particularly by means of at least one plug-in and / or clamping connection. This further simplifies installation and disassembly.

[0031] Preferably, the baffle can be constructed in multiple pieces, especially in two pieces, and is provided and adapted to secure the housing (which is also constructed in multiple pieces, especially in two pieces) and thereby secure the housings relative to each other. Thus, the baffle performs two main functions. On the one hand, in the assembled state, the baffle, through its baffle opening, improves the reception of the transponder in terms of signal technology; and simultaneously, the baffle provides mechanical, form-fitting fixation and security for the multi-piece housing.

[0032] Preferably, the baffle can be constructed in multiple parts and has a first baffle segment and a second baffle segment, the first baffle segment and the second baffle segment being able to be in a form-fitting engagement and / or disengagement with each other by a locking mechanism. In the present context, the term locking engagement refers to the operative engagement of the form-fitting locking mechanism, wherein movement of the first baffle segment relative to the second baffle segment in a direction opposite to the direction in which the first baffle segment and the second baffle segment have been combined is prevented or at least severely impeded.

[0033] According to the embodiment, the first and second baffle segments can prevent the transponder from being inserted into and removed from the housing in a form-fitting locking engagement. The mechanical locking of the locking mechanism ensures that the transponder, especially the glass tag, is reliably and permanently positioned within the housing, particularly between the two housing components.

[0034] In particular, the baffle is constructed as a planar or sheet-like object, especially flat / flat, and has a constant height (thickness) perpendicular to the baffle opening, similar to an elongated washer. In the case of a curved baffle, especially one with a constant bending radius (which preferably corresponds to the radius of the instrument body surface), the baffle can also have a constant thickness.

[0035] More preferably, the first baffle segment and the second baffle segment can be the same component / identical component. In particular, the baffle opening can have an elongated or slit-shaped design with a longitudinal axis of the baffle opening. In this case, the two baffle segments preferably have a U-shaped design, wherein a locking protrusion extending orthogonally to the longitudinal axis of the baffle opening is formed on the first free end, and a complementary locking recess extending orthogonally to the longitudinal axis of the opening is formed on the second free end. In particular, the locking protrusion and the locking recess point in the same direction, such that when the first baffle segment is rotated 180° relative to the second baffle segment about the longitudinal axis of the baffle opening, the two identical baffle segments can lock into each other at their two free ends. The locking protrusion then engages with the locking recess. In particular, when viewed from the baffle opening, the locking protrusion points outward and the locking recess faces the baffle opening. More preferably, the locking protrusion is constructed in the form of a particularly symmetrical, arched convex hill, similar to a P-shape, and the locking recess is constructed in the form of a complementary, particularly symmetrical, concave depression. In particular, the U-shaped baffle segment has a surrounding rectangular cross-section with a constant dimension, wherein the dimension (width) decreases only orthogonally to the longitudinal axis of the baffle opening in the region of the free ends of the locking protrusion and the locking recess, making the width of the locking protrusion and the locking recess smaller. Specifically, the locking protrusion retracts towards the baffle opening relative to the outer side of the baffle segment facing away from the baffle opening, and / or the locking recess retracts towards the inner side of the baffle segment facing the baffle opening.

[0036] According to another preferred embodiment of the invention, the baffle can be made of metal, particularly entirely of metal. Preferably, the baffle is made of stainless steel. Metal is impermeable to electromagnetic waves. Stainless steel can be sterilized particularly well.

[0037] Further preferably, the baffle opening serving as a channel for electromagnetic waves or signals, especially radio signals, is configured to be elongated or slit-shaped and has a width corresponding to the product of the coil diameter (of the transponder, especially the glass tag) and an ideality factor, wherein the ideality factor is in the range of 1.3 to 2.2, more preferably in the range of 1.6 to 1.9, and particularly preferably 1.75. In other words, the baffle opening parallel to the transponder, especially the glass tag, has a width greater than the coil diameter and / or width of the transponder, especially the diameter of the glass tag.

[0038] More preferably, the elongated or slit-shaped baffle opening has a length that is -30% to +50% of the total length of the transponder's coil core, especially the ferrite core; more preferably, it is 0% to +30% of the total length of the ferrite core; and particularly preferably, it is +15% of the total length of the ferrite core. In other words, the baffle opening parallel to the transponder, especially the glass tag, has a length that is preferably greater than the length of the coil core, especially the ferrite core, and / or the length of the transponder, especially the glass tag.

[0039] In particular, the housing may have a first housing member and a second housing member, with the transponder fixedly housed between these housing members, wherein a baffle secures the first housing member to the second housing member.

[0040] Preferably, the housing can be composed of exactly two housing parts and the baffle can be composed of exactly two baffle segments. Therefore, the number of parts is minimized and assembly is convenient.

[0041] According to another preferred embodiment, the second housing member may be U-shaped with a semi-circular / semi-cylindrical housing base and two connected parallel cylindrical housing pins / retaining arms, the housing pins / retaining arms having rounded heads that can be inserted into two parallel complementary receiving / fitting openings constructed in the first housing member in the form of a form-fitting interlocking connection, wherein the baffles, in the combined state, form-fittively surround the two housing members and are fixed relative to each other. Preferably, the second housing member has a stepped shape with at least two different diameters when viewed from the bottom to the top in its semi-cylindrical housing base. This produces a type of graded longitudinal section, wherein the baffles or baffle segments can be inserted into the steps with the smaller diameter in such a way that the baffles abut against the housing base and, particularly when the diameter of the housing base (with the larger diameter) and a portion of the outer wall of the baffle are the same, they end flush with each other. Alternatively, the baffle may be slightly retracted into the housing relative to the outer side of the housing base, so that the baffle does not contact the inner wall of the pre-prepared recess or opening in the inserted state and only the housing rests against the recess or opening.

[0042] Preferably, only two pins form the outer surface of the housing, which extends outward toward the side of the housing, abuts against the inner wall of a pre-prepared recess or opening, and, in particular, causes compression or pressing in the recess or opening by means of its inherent elasticity.

[0043] Preferably, a circumferential groove opening outwards towards the outside of the housing is formed in the upper region of the housing, into which a baffle can be inserted. In particular, the baffle inserted into the circumferential groove ends flush with the outside of the housing or retracts into the housing interior relative to the outside.

[0044] Furthermore, preferably, the housing may be made of thermoplastic, especially polypropylene (PP), and particularly preferably entirely of thermoplastic. Thermoplastic is permeable to electromagnetic waves and is advantageous and simple to manufacture.

[0045] Preferably, the housing of the transponder mounting module, especially the upper side, may be colored or color-coded, allowing information to be assigned to the transponder mounting module during color coding. Therefore, it is also possible to provide device systems with adapters for both the medical device and the compatible transponder mounting module. Preferably, only the first transponder mounting module, identified by the first color, can be inserted into the first medical device having a first pre-prepared recess or opening, and the second medical device can only accommodate the second transponder mounting module, identified by a different second color. This, for example, ensures that only the first transponder mounting module individually adapted to the first medical device is used for the first medical device, and only the second transponder mounting module individually adapted to the second medical device is used for the second medical device. Different colors can thus be used for structural management and identification. As an alternative or supplement to color, the geometry of the recess or opening and the housing can also be selected with correspondingly different fitting methods to prevent unintentional confusion.

[0046] In particular, the housing has a planar upper side and a planar lower side, as well as a surrounding, especially closed side arranged between the upper and lower sides, so that the positional transponder is circumferentially confined relative to the surrounding environment.

[0047] In particular, the upper side can be constructed flat and the plane of the baffle opening is parallel to the upper side. Preferably, the lower side can also be constructed flat and the plane of the baffle opening is parallel to the lower side. In particular, the flat planes of the upper side, the lower side, and the baffle opening are parallel to each other.

[0048] Preferably, the first housing member forms the upper side. Furthermore, even more preferably, the first housing member constitutes more than half of the lower side. Therefore, the second housing half primarily serves to enclose the housed transponder and is preferably used for press-fitting, while the first housing member provides mechanical shielding via the upper side in the inserted state.

[0049] Preferably, the housing may have rounded or cut edges on its underside. This improves centering and insertion into pre-prepared recesses or openings with the underside facing forward.

[0050] Preferably, the first housing member can be connected to the second housing member by a plug-in connection, and more preferably, the plug-in connection can be prevented from falling off by means of a press fit.

[0051] According to embodiments of the invention, a cylindrical recess / drill hole can be introduced into the housing, particularly in the first housing member, into which a cylindrical transponder can be inserted. Preferably, the diameter of the recess is adapted in terms of the geometry of the transponder to construct a press fit. In particular, the diameter of the recess is exactly equivalent to the diameter of the cylindrical transponder. Alternatively, this diameter is preferably slightly smaller than the diameter of the transponder to construct a friction-fit press fit. Preferably, the recess is arranged parallel to the housing pins and symmetrically between the housing pins in the assembled state. Preferably, the recess is parallel and symmetrically positioned between two slotted receptacles of the first housing member that open toward the respective outer sides of the housing. In other words, the housing, particularly the first housing member, can have three parallel holes, wherein one hole is arranged between the other two holes, and one cylindrical hole leads to a reinforcing material (ins Volle), and the other two holes are only half-open to their respective opposite outer sides.

[0052] According to another embodiment of the invention, the housing and / or baffle may be provided with a biocidal agent, thereby further reducing the risk of bacterial formation.

[0053] According to embodiments of the invention, the housing, particularly the first housing member, may have a thin, planar, rectangular, and especially flat cover with rounded corners as its upper side. Viewed from the upper side, this cover covers the entire housing and is therefore a type of protective cover for a transponder mounting module. In particular, the cover is designed in a tab-like shape around its sides, allowing the transponder mounting module to be easily and manually removed. Specifically, in the first housing member, a surrounding groove with an outward opening can be constructed in a plane parallel to the cover, between the cover and the lower side, particularly directly below the cover, into which the cover can be inserted.

[0054] According to an embodiment of the invention, the transponder has a cylindrical shape, particularly with rounded ends, the cylindrical shape having a transponder longitudinal axis, and the baffle opening of the baffle is configured as elongated or slit-shaped and has a baffle opening longitudinal axis, wherein the transponder longitudinal axis is parallel to and spaced apart from the baffle opening longitudinal axis. In particular, the baffle opening points upwards.

[0055] According to another preferred embodiment, the upper and lower sides can be constructed flat and parallel to each other, wherein the longitudinal axis of the transponder and the longitudinal axis of the baffle opening are located in the plane of symmetry of the housing, and the plane of symmetry intersects the upper and lower sides perpendicularly.

[0056] Preferably, the transponders are centered and symmetrically arranged relative to the baffle opening when viewed from above. This positions the transponders in the middle of the baffle opening and improves reception.

[0057] Preferably, the transponder can be a passive RFID transponder.

[0058] Preferably, the transponder is an RFID transponder, and more preferably a glass tag, for storing information belonging to a specific medical device. This RFID transponder is suitable for personalization according to the requirements of a predefined process. The RFID transponder or RFID tag particularly possesses:

[0059] Microchips, preferably with a size of less than 2 mm,

[0060] The antenna, preferably in the form of a coil, is particularly preferably having an inner rod-shaped ferrite core around which the coil is wound.

[0061] The outer casing, preferably waterproof and / or airtight, and preferably protects the electronic components of the transponder from the surrounding environment.

[0062] According to another embodiment, the transponder may also be an active RFID transponder, which has at least one power source, preferably in the form of a battery, a storage battery, and / or a capacitor.

[0063] Preferably, the transponder is configured and adapted to store at least one of the following information, either encrypted or unencrypted:

[0064] Under normal circumstances,

[0065] Lifespan / End of lifespan

[0066] Maintenance interval,

[0067] The performance and applicability of subsequent surgeries

[0068] Inadequate product maintenance and potential product damage

[0069] Excessive heat or cold, and potential product damage.

[0070] Item number,

[0071] Serial number, and / or

[0072] client.

[0073] Therefore, it is possible, in medical devices, especially when combined with personalized support, to detect, count, and store processing cycles within the medical device itself. In particular, this allows for the detection of whether all necessary process steps have been followed and performed. The number of processing cycles can, in particular, be a proportional measure of the aforementioned information.

[0074] Preferably, the transponder has a cylindrical shape with rounded ends. The shape of the transponder, especially the glass tag, is particularly round.

[0075] According to a preferred embodiment, the glass label may have a diameter of 2 mm and a length of 12 mm. Alternatively, the dimensions may preferably be a diameter of 3 mm and a length of 13 mm, or more preferably a diameter of 4 mm and a length of 22 mm.

[0076] Furthermore, the transponder can preferably be used in a frequency band in the range of 12 to 15 MHz, advantageously in a frequency band in the range of 13 to 14 MHz, more preferably in a frequency band in the range of 13.4 to 13.7 MHz, and particularly preferably in a frequency band of 13.56 MHz.

[0077] Preferably, the medical device can be a surgical instrument, a monopolar HF device, a bipolar HF device, an electrosurgical instrument, an ultrasonic instrument, a surgical clamp, a surgical forceps, a surgical scissor, or a scalpel. In particular, the medical device can be a handheld device with an integrated motor and / or a tool that can be coupled to the handheld device.

[0078] Preferably, the transponder mounting module is configured to be inserted into the medical device from below, such that the transponder mounting module does not protrude from the surface.

[0079] Medical devices, in particular, have elongated holes in their surfaces that serve as pre-prepared openings into which transponder mounting modules are inserted.

[0080] According to an embodiment, a medical device may have a keyway or groove in its body surface as a pre-prepared recess, the keyway or groove having, in particular, rounded corners and / or ends.

[0081] In principle, the geometry and material of the housing of the medical device and / or transponder mounting module, as well as the orientation of the transponder relative to the corresponding device body surface, can be freely chosen and primarily depends on the shape of the transponder mounting module. However, preferably, the orientation of an elongated transponder, especially the orientation of the coil, is such that the transponder is oriented parallel to the outer surface of the medical device body in its longitudinal direction in the inserted state (i.e., "flat"). The housing can, in particular, be selectively left free / open or filled / closed with a material that allows signal transmission. Specifically, the transponder itself can be molded as a closed enclosure such that when the transponder (through the baffle opening) is inserted into the housing, the housing or the opening of the housing is closed outwards (watertight / airtight) by the transponder itself.

[0082] The objective of this invention is achieved in the context of a medical transponder system / transponder communication system by comprising a transponder mounting module or a medical device according to the invention having a transponder mounting module and a read and / or write device that can be signal-technically coupled to the transponder.

Detailed Implementation

[0105] Figures 1 to 10 The medical device 101 according to the present invention, showing a preferred embodiment (see...) Figure 12 The transponder mounting module 1 is configured and adapted for insertion into a pre-prepared recess 103 in the surface 104 of the medical device 101. Figure 1 An exploded perspective view of the transponder mounting module 1 is shown, illustrating the various components of the transponder mounting module 1 before assembly. Figure 1 After Figures 2 to 4 Demonstrates the step-by-step toolless assembly of each component, until... Figure 4 The image shows the completed installation of the transponder installation module 1 in its combined state. Figures 5 to 8 As shown in the view below Figures 1 to 4 Transponder installation module 1.

[0106] Specifically, the transponder mounting module 1 has a single pin-shaped or round transponder in the form of a glass tag 2 with a longitudinal axis L, the outer casing of which is constructed of glass with rotational symmetry. In this embodiment, the glass tag 2 is preferably an embeddable RFID (Radio Frequency Identification) glass tag with a frequency of 13.56MHz.

[0107] The glass tag 2 is held in place by means of a housing 3 made of thermoplastic, preferably polypropylene. Thermoplastic and, in particular, polypropylene are cost-effective materials suitable for injection molding; however, they are permeable to electromagnetic signals, especially radio frequency signals. Therefore, the housing 3 provides a good structural support for the glass tag 2 without affecting its signal technology. Furthermore, as will be described in detail below, the housing 3 is configured to insert into a pre-prepared recess 103 or depression in the medical device 101 (see...). Figure 12 ).

[0108] In addition to the housing 3, which allows signals to pass through, the transponder mounting module 1 according to the invention has a multi-piece baffle or reinforcing baffle 4 made of a non-transmissible or conductive material, which in this embodiment is metal. In the assembled or combined state, the baffle 4 has a baffle opening 5 that is offset relative to the upper side 6 of the transponder 2 facing the transponder mounting module 1, and its special geometry and position significantly improve the reception of the glass tag 2. In particular, the baffle 4 increases the possible distance to a reading and writing device, which can read, modify, and / or write to the transponder.

[0109] With this specific design of the transponder mounting module 1, the baffle 4 is arranged between the transponder 2 and an external read / write device that can be positioned in the area above the transponder mounting module 1, wherein the baffle opening 5 points not only to the transponder 2 but also to the area above the module 1, 6. This arrangement is also applicable to the state when inserted into the medical device 101.

[0110] By increasing the signal range or maximizing the possible signal range, the reception of transponders in the form of glass tag 2 is improved, thus achieving reliable, stable, and secure communication. Furthermore, it enables the independent, or at least more independent, development of medical devices. Because the immediate surrounding environment of the transponder's structure is primarily predetermined by the transponder mounting module 1, which essentially determines the transmission, no additional adaptation to the medical device is required for transponder reception.

[0111] The transponder mounting module 1 can also be better and more flexibly integrated into the medical device 101 (see [link]). Figure 12The medical device 101 requires only a pre-prepared recess or opening on or within the surface of the device body to mate with the housing 3. The transponder mounting module 1 is inserted into the recess or opening with its lower side 7 pointing towards the recess, such that the lower side 7 is retracted relative to the upper side 6 of the transponder mounting module 1 and thus relative to the device body surface 104. In particular, the shape of the transponder mounting module 1 allows it to be inserted bottom-mounted, so that the upper side 6 terminates flush with the device body surface 104 or retracts towards the interior of the device body relative to the device body surface.

[0112] In this embodiment, the upper side 6 and lower side 7 of the housing 3 are two flat surfaces that are parallel to each other and limit the transponder mounting module 1 to the upper and lower sides relative to the surrounding environment (in terms of material).

[0113] More precisely, housing 3 in its assembled state (see...) Figure 4 and Figure 8 The transponder mounting module 1 has three main sides: firstly, a rectangular lower side 7 with rounded corners and a flat, flat surface; secondly, a rectangular upper side 6 with rounded corners and a flat surface parallel to the lower side, which is larger in area than the lower side 7; and thirdly, a surrounding outer wall 8 arranged between the lower side 7 and the upper side 6, which encloses the transponder. Here, the outer wall 8 follows the outer contour of the lower side 7 and extends perpendicular to both the lower and upper sides 6, forming a wall of a certain type. Thus, the transponder mounting module 1 is enclosed relative to the surrounding environment (planarly) in its assembled state.

[0114] Besides insertion, replacing the transponder mounting module 1 is also particularly simple. This is because the transponder mounting module 1 does not need to be fastened to the medical device, for example by welding or screwing, and then correspondingly laboriously loosened; instead, it can be simply inserted without tools into the pre-prepared recess 103 of the medical device 101 (see...). Figure 12 And then removed from the recess. By using thermoplastic as the material and the geometry of the housing 3 (which will be described in more detail below), the housing 3 has a certain inherent elasticity in the direction parallel to the upper side 6 so as to induce a press fit or compression in the inserted state. Since the structural conditions or parameters important for transmission have already been implemented in the transponder mounting module 1 itself, the medical device can selectively have a core that is both signal-transmitting and signal-intransitive.

[0115] In its assembled state, the baffle 4 has a flat, elongated O-shaped form with a constant wall thickness in both its own plane and in planes orthogonal to it. A central, elongated, or slit-shaped baffle opening 5 is created by a frame of the same shape as the baffle 4. This opening is also O-shaped and axially symmetrically constructed, and has a longitudinal axis B. In this embodiment, due to the symmetrical construction, the longitudinal axis B of the baffle opening is simultaneously the longitudinal axis of the baffle 4.

[0116] Specifically, the longitudinal axis L of the glass tag is parallel to the longitudinal axis B of the baffle opening, wherein the longitudinal axis L of the glass tag is retracted towards its lower side 7 relative to the longitudinal axis B of the baffle opening. The longitudinal axis L of the glass tag and the longitudinal axis B of the baffle opening define a plane that is the plane of symmetry of the housing 3 for the transponder mounting module 1.

[0117] The glass tag 2 is particularly small, which, together with the small housing 3, allows for the small size of the transponder mounting module 1.

[0118] The transponder mounting module 1 of the present invention is characterized by a multi-piece baffle 4, or a two-piece design in this embodiment. Through the two-piece implementation of the baffle 4, in conjunction with the multi-piece, or two-piece housing 3 in this embodiment, not only signal enhancement but also structural fixation of the two-piece housing 3 can be achieved, as described below.

[0119] The two-piece housing 3 specifically comprises a first housing member 3a and a second housing member 3b, distinct from the first housing member. The integrated first housing member 3a is designed to be axisymmetric and mirror-symmetric, forming the main portions of the upper side 6 and lower side 7 of the plane. Centrally located between the upper side 6 and lower side 7 and within the mirror-symmetric plane, the first housing member 3a has a mushroom-shaped or cylindrical recess / drill hole 9 corresponding to the size of the glass label 2, allowing the glass label to be inserted into the recess 9. Preferably, the size of the recess 9 can be selected relative to the size of the glass label 2 to create a press fit. Thus, the glass label 2 is protected from accidental drops and can only be removed by pulling force along the longitudinal axis L of the glass label. Alternatively, a radial gap can be provided between the circularly cross-sectional recess 9 and the circularly cross-sectional glass label 2, allowing for particularly easy insertion and removal of the glass label. In other words, the diameter of the recess can be slightly smaller than or equal to the diameter of the glass label 2, thereby setting a press fit, or the diameter of the recess 9 can be designed to be slightly larger, so that the glass label can be easily inserted and removed with a gap.

[0120] At the same height as and parallel to the recess 9 between the upper side 6 and the lower side 7, the first housing member 3a has semi-circular grooves / basins 10 that open outwards toward the sides, symmetrically offset from their respective sides. The two grooves 10 are again constructed in mirror symmetry with respect to the inserted glass label 2 having a longitudinal axis L and are used to receive the second housing member 3b.

[0121] The second housing member 3b is constructed in a mirror-symmetrical manner, identical to the first housing member 3a. The second housing member is U-shaped, having a semi-circular or semi-cylindrical housing base 11 and two parallel extending cylindrical housing pins / pins 12 connected to the housing base 11. For easier insertion, the housing pins 12, with rounded heads, are positioned and constructed to engage in the groove 10 and serve as a plug-in connection. The diameter of the housing pins 12 corresponds to the diameter of the groove 10. Similar to the recess 9, a press-fit or fit with a gap can be established by coordinating the diameter of the housing pins 12 with the diameter of the groove 10. Similarly, by coordinating a distance slightly smaller between the longitudinal axes of the housing pins than between the longitudinal axes of the grooves, a clamping force, along with the accompanying friction between the housing pins 12 and the groove 10, can be achieved, ensuring that the second housing member 3b is forcefully fixed relative to the first housing member 3a and preventing accidental separation. Then, the second housing member 3b can only be pulled out relative to the first housing member 3a by a pulling force parallel to the longitudinal axis of the pins.

[0122] For assembly, the second housing component 3b is as follows: Figure 2 and Figure 3 or Figure 5 , 6 As shown, the glass label 2 moves translationally along its longitudinal axis L. The housing pin 12 then engages in the groove 10, and finally the housing base 11 rests against the first housing member 3a. The two housing members 3a and 3b can only move in the direction along the longitudinal axis L.

[0123] In the assembled state of housing 3, see Figure 3 , 7 or Figure 4 , 8 The two housing components 3a and 3b enclose the glass label 2 between the two housing components and thus protect or limit the glass label relative to the surrounding environment.

[0124] To prevent the two housing parts 3a and 3b from accidentally coming apart, they are secured or fixed together by a tool-less, form-fitting two-piece baffle 4. In this embodiment, the two-piece baffle 4 has a U-shaped first baffle segment 4a and a U-shaped second baffle segment 4b, which respectively surround the two housing parts 3a and 3b on their outer peripheries (see...). Figure 4 and Figure 8Furthermore, the first and second baffle segments can be interconnected via a form-fitting locking mechanism / clamping system 13. In the combined state where the two baffle segments 4a and 4b are locked and interconnected, separation of the two housing parts 3a and 3b along the longitudinal axis L of the glass label 2 is prevented because the two-piece baffle 4 surrounds the first and second housing parts 3a and 3b on its outer periphery and holds them together like a rigid rope. Therefore, the baffle 4 not only functions as a signal amplification element for the transponder but also as a fixing element that holds the housings 3 together.

[0125] The two baffle segments 4a and 4b are identical components, wherein the second baffle segment 4b is rotated only 180° relative to the first baffle segment 4a about the longitudinal axis B of the baffle opening. Therefore, the structure of the first baffle segment 4a will be described below only.

[0126] The first baffle segment 4a, made of metal, particularly stainless steel, has a rectangular profile in cross-section that extends in a U-shape. The baffle segment 4a is generally flat or lies in a plane. Furthermore, at the first free end 16, the first baffle segment 4a has a locking protrusion 14 in the form of a convex hill extending orthogonally to the longitudinal axis B of the baffle opening and lying in the aforementioned plane, the locking protrusion facing away from the second free end 17. Additionally, at the second free end 17, the baffle segment has a complementary locking recess 15 in the form of a groove, orthogonal to the longitudinal axis B of the baffle opening, extending orthogonally to the hill, facing the first free end 16. Here, the locking protrusion 14 and the locking recess 15 point in the same direction.

[0127] The card lock effect is below and in Figure 9 As shown in the diagram, the first free end 16 of the first baffle segment 4a is guided to the second free end 17 of the second baffle segment 4b. Here, the locking recess 15 of the first baffle segment 4a first abuts against the actuating surface 18 in the region of the complementary locking protrusion 14 of the second baffle segment 4b. If the two baffle segments 4a, 4b are now further pushed toward each other, the second free end 17 elastically offsets outward substantially orthogonally to the longitudinal axis B of the baffle opening, overcoming the inherent stress of the baffle segment 4a, due to the geometry of the locking recess 15 abutting against the actuating surface 18, such that the locking recess 15 is subsequently above the actuating surface 18 and the first free end 16 can be displaced relative to the second free end 17. Similarly, this process occurs together with the first free end 16 of the second baffle segment 4b on the second free end 17 of the first baffle segment 4a.

[0128] If the two baffle segments are now further displaced relative to each other, the corresponding locking recess 15 locks into the locking protrusion 14 and the second free end 17 is again offset rearward in the pre-tightening direction. The first baffle segment 4a and the second baffle segment 4b are in a form-fitting locking engagement and secure the first housing member 3a to the second housing member 3b. Thus, the locking protrusion 14 and the locking recess 15, together with the U-shaped shape of the baffle segment 4a that ensures a certain degree of elasticity, form the locking mechanism 13.

[0129] By adapting the shapes of the locking protrusions and complementary locking recesses, the desired deflection force can be specifically set. For example, the shape of the locking teeth can be used instead of the hill shape. This prevents or at least hinders the removal of the transponder mounting module when the locking is engaged.

[0130] In order for the baffle 4 to completely surround the housing 3, the housing 3 has a groove 20 surrounding its outer side 8. Specifically, the first housing member 3a has a U-shaped surrounding first groove 20a into which the first baffle segment 4a and a section of the second baffle segment can be inserted, and the second housing member 3b has a U-shaped second groove 20b on its housing base 11 that is adapted to the second baffle segment 4b, and the second baffle segment 4b can be inserted into the second groove in a form fit.

[0131] It should be noted that the two baffle segments 4a and 4b can of course rotate 180° around the longitudinal axis of the baffle opening and also perform the same function.

[0132] A flat, thin cover 19 with rounded corners forms the upper side 6 and, in the inserted state, is positioned relative to the surrounding environmental protection transponder mounting module 1. A transition portion 21 on the outwardly pointing side of the housing pin 12 defines a reduction in the maximum distance between the outer surface of the housing pin 12 and the housing base, such that the diameter of the housing base 11 is equal to this distance. Therefore, the section of the housing pin 12 without the transition portion 21 is used for press-fitting, because there the distance between the opposing surfaces is (slightly) larger.

[0133] exist Figure 10 The diagram shows the main clamping force of the recess 103 in the inserted state on the two housing pins 12, which has the maximum width of the housing 3, protrudes to a certain extent and thus rests against the corresponding inner side of the recess 103.

[0134] Figure 11Another embodiment of the transponder mounting module 1 is shown. In this embodiment, the transponder mounting module 1 has a color code on its upper side 6 in the form of a green surface. Multiple functions can be achieved through color coding. For example, a new color can be used when the transponder mounting module 1 is replaced, making it visually apparent to the user which device has been equipped with the new transponder mounting module. Alternatively or additionally, a specific color can be specified to be compatible only with a specific medical device, similar to size or identification indicators. For example, the manufacturing or replacement date of the transponder mounting module 1, similar to a vehicle emblem, can also be indicated by color.

[0135] Figure 12 A medical device 101 according to the invention is shown with a preferred embodiment of an inserted transponder mounting module 1. The transponder mounting module 1 is inserted into a fitted, pre-prepared recess 103 in a sleeve-shaped coupling section 102 on the distal region of the medical device 101. Specifically, the recess 103 is constructed in the form of an elongated groove having rounded ends and the same depth relative to the device body surface 104. The housing 3 and the recess 103 are coordinated to each other such that the transponder mounting module 1 has a press fit in the medical device 101, making tool-free insertion and removal of the transponder mounting module 1 possible. The upper side 6 of the transponder mounting module 1 ends flush with the device body surface 104, thereby obtaining a flat device body surface with a certain degree of absence of lateral recesses or protrusions. In particular, the recess 103 may be constructed in a stepped shape along the recess direction V (not shown here).

[0136] In an alternative implementation, the upper side of the transponder mounting module can also be convex to better fit or conform to the cylindrical shape.

[0137] Figure 13 Show Figure 12 The medical device 101 is coupled to a handheld device 105. A metal sleeve section 106 of the handheld device 105 covers the transponder mounting module 1, thereby protecting the transponder mounting module mechanically and signal-technically relative to the surrounding environment and preventing it from being read when coupled to the handheld device 105. Furthermore, the transponder mounting module 1 is additionally protected against dropping.

[0138] Figures 14 to 19 Various medical devices 101 with a preferred embodiment of the transponder mounting module 1 are shown in perspective or top view. Specifically, Figure 14 A medical punch cutter with a transponder mounting module 1 is shown. Figure 15 A medical punch or surgical scissors with a transponder mounting module 1 is shown. Figure 16 An additional medical punch with transponder mounting module 1 is shown. Figure 17A medical clamp with a transponder mounting module 1 is shown. Figure 18 An additional medical clamp with a transponder mounting module 1 is shown, and Figure 19 A medical forceps with a transponder mounting module 1 is shown. In particular, the transponder mounting module 1 of one embodiment can thus be inserted into a number of different medical devices 101, which in particular have standardized pre-prepared recesses 103 or openings.

[0139] Figure 20 and Figure 21 A preferred embodiment of the medical transponder system / medical transponder communication system 201 according to the invention is shown, comprising a transponder mounting module 1 inserted into a medical device 101 according to the invention and a compatible read and write device 202. Alternatively, of course, only a read device or only a write device may be used.

[0140] exist Figure 20 In this embodiment, the transponder mounting module 1 is inserted into the handheld component of the medical device 101. Because the handheld component is made of metal, the transponder 2 cannot be read from the outside; instead, reading and / or writing activities must be performed inside the handheld component. This is achieved by arranging a reading and writing device 202 on or within the surface of the battery 204 of the medical device. If the battery is introduced into the handheld component and securely inserted, the transponder is written to and / or read by the reading and writing device 202 located inside the handheld component. Alternatively, the reading and writing device 202 may be specified to initiate writing and / or reading upon removal of the battery.

[0141] Figure 21 A transponder system 201 with an alternative embodiment is shown. This transponder system has a holding system 203 to allow a medical device 101 with an inserted transponder mounting module 1 to be introduced into a predetermined arrangement relative to a read and write device 202 and subsequently held in that position and location during communication, thereby ensuring safe and reliable transmission.

[0142] Figure 22 The glass tag 2 is shown in a top view. The glass tag has an RFID chip, a rod-shaped ferrite core, and a coil wound around the ferrite core. For better observation, in... Figure 22 The outer cover is omitted from the lower part.
