    Field of the disclosure
    The disclosure relates to an instrument cassette for handling instruments which can 5 be, for example but not necessarily, medical or dental hand instruments. The instrument cassette can be used for holding instruments for example when the instruments are sterilized by autoclaving.
    Background
    In many cases, authorities and actors of the medical or dental field want to have an 10 infallible and traceable solution to follow instruments to be able to trace disinfection, sterilization, reparation, clinical use, and other operations targeted to or carried out with the instruments under consideration. Nowadays, users do not typically have the time and willingness to generate reports manually because of the related workload.
    In addition, there is a risk of errors with manual data recording and identification of 15 instruments, which prevents regarding the manually recorded data as an irrefutable proof of what has been done and what has been not done.
    A known solution for tracing operations directed to or carried out with instruments is to provide each instrument with a unique identifier such as e.g. radio frequency identifier “RFID”. For example, publication W02008062387 describes an instrument 20 comprising a radio frequency identifier. The radio frequency identifier is embedded in a polymer sheet that is attached on a surface of the handle of the instrument. The polymer sheet that includes the radio frequency identifier can be, for example, wrapped around the handle of the instrument. In order to obtain an even surface, it is possible to provide the instrument with a recess corresponding in size to the 25 polymer sheet. In an advantageous embodiment described in W02008062387, the polymer sheet comprises two layers between which the radio frequency identifier is located. In many cases, there can be however a need to trace operations directed to or carried out with particular instrument sets. Thus, there is a need for additional technical solutions for being able to trace operations directed to or carried out with 30 instrument sets.

    Brief description of figures
    Exemplifying and non-limiting embodiments and their advantages are explained in greater detail below in the sense of examples and with reference to the accompanying drawings, in which:
    figures 1a, 1b, 1c, 1d, and 1e illustrate an instrument cassette according to an exemplifying and non-limiting embodiment, figures 2a, 2b, 2c, and 2d illustrate an instrument cassette according to an exemplifying and non-limiting embodiment and a process for installing a radio frequency identifier “RFID” in the instrument cassette, and figures 3a and 3b illustrate an instrument cassette according to an exemplifying and non-limiting embodiment.
    Description of exemplifying and non-limiting embodiments
    The specific examples provided in the description below should not be construed as limiting the scope and/or the applicability of the accompanied claims. Lists and 20 groups of examples provided in the description are not exhaustive unless otherwise explicitly stated.
    Figures 1a, 1b, 1c, 1 d, and 1e illustrate an instrument cassette 100 according to an exemplifying and non-limiting embodiment. Figure 1a shows a top view of the instrument cassette, figure 1b shows a side view of the instrument cassette, figure 25 1c shows a bottom view instrument cassette, figure 1d shows a view of a section taken along a line A-A shown in figure 1c, and figure 1e shows a view of a section taken along a line B-B shown in figure 1c. The section plane related to figure 1d is parallel with the yz-plane of a coordinate system 199, and the section plane related
    20175681 prh 12 -07- 2017 to figure 1e is parallel with the xz-plane of the coordinate system 199. The instrument cassette 100 comprises a body section 101 for holding instruments such as e.g. medical or dental hand instruments. In the exemplifying situation shown in figures 1a-1c, there are three exemplifying instruments in the instrument cassette
    100. One of the exemplifying instruments is denoted with a reference 111. The instruments are not shown in the section views shown in figures 1d and 1e. The exemplifying instrument cassette 100 comprises two sections 113 and 114 for the operational portions of the instruments. An operational portion can be for example a blade of a knife. It is, however, also possible that there is only one section for 10 operational portions of instruments. The material of the body section 101 is advantageously electrically non-conductive so that radio frequency radiation can penetrate the material of the body section. The material of the body section 101 may comprise for example plastic that may comprise e.g. polyphenylene sulfide “PPS”.
    The instrument cassette 100 comprises cover elements 107 and 108 for covering 15 the rooms for containing the operational portions of the instruments so as to prevent unintentional touching the operational portions of the instruments. In the exemplifying instrument cassette 100, the cover elements 107 and 108 are hinged to the body section 101. It is, however, also possible that a cover element or cover elements is/are shape locked or otherwise mechanically connected to a body 20 section of an instrument cassette according to an exemplifying embodiment. It is also possible that an instrument cassette according to an exemplifying embodiment does not comprise any cover element of the kind mentioned above. In the exemplifying situation shown in figures 1a and 1b, the cover element 108 is in an opened position. The cover elements 107 and 108 are advantageously provided 25 with apertures which facilitate hot vapor to get in contact with the operational portions of the instruments during an autoclaving sterilization process. In figure 1a, one of the apertures of the cover element 107 is denoted with a reference 109. Correspondingly, the bottoms of the sections 113 and 114 for containing the operational portions of the instruments are advantageously provided with apertures. 30 In figures 1a and 1c, one of the apertures of the bottom of the section 114 is depicted with a reference 110. Furthermore, also the side walls of the sections 113 and 114 can be provided with apertures.
    20175681 prh 12 -07- 2017
    The instrument cassette 100 comprises a radio frequency identifier “RFID” that is readable from a distance away from the radio frequency identifier. In figures 1d and 1e, the radio frequency identifier is denoted with a reference 102. In this exemplifying case, the radio frequency identifier 102 is located in a cavity 103 of the 5 body section 101. The instrument cassette 100 comprises a closing element 104 that closes the opening of the cavity 103 and constitutes, together with the surfaces of the cavity, a room for the radio frequency identifier 102. Advantageously, the radio frequency identifier 102 is substantially not attached to the body section 101 directly but the closing element 104 keeps the radio frequency identifier 102 stationary with 10 respect to the body section 101. In this exemplifying case, it is straightforward to replace the radio frequency identifier 102 with another radio frequency identifier after the closing element 104 has been removed. Advantageously, the closing element 104 and the surfaces of the cavity 103 constitute a hermetically sealed room for the radio frequency identifier 102. In this exemplifying case, the radio frequency 15 identifier 102 is protected against environmental conditions such as e.g. hot vapor used in an autoclaving sterilization process. The closing element 104 can be made of flexible material that may comprise for example silicone. It is however also possible that a radio frequency identifier of an instrument cassette according to another exemplifying embodiment is attached to a surface of a cavity so that there 20 is no need for a closing element for closing the opening of the cavity. Furthermore, it is also possible that a radio frequency identifier of an instrument cassette according to an exemplifying embodiment is attached on a surface of the body section or another element of the instrument cassette so that the radio frequency identifier is not in a cavity or similar.
    The radio frequency identifier 104 can be, for example but not necessarily, a ceramic radio frequency identifier tag. The radio frequency identifier 102 may comprise, for example but not necessarily, a memory circuit capable of storing digital information.
    The digital information may contain for example identifying information identifying the instrument cassette 100 as an individual object from among similar instrument 30 cassettes and/or information indicating e.g. the date of manufacture of the instrument cassette, the manufacturer of the instrument cassette and/or other information related directly or indirectly to the instrument cassette. Furthermore, the
    20175681 prh 12 -07- 2017 digital information may indicate the number of sterilization cycles carried out using the instrument cassette 100. It is, however, also possible that the radio frequency identifier 102 does not comprise any memory circuit but identification information related to the radio frequency identifier 102 is represented by e.g. radiation properties of the radio frequency identifier 102.
    In the exemplifying instrument cassette 100 illustrated in figures 1a-1e, the cavity 103 is an elongated groove. The radio frequency identifier 102 comprises an elongated antenna structure, and the closing element 104 is an elongated bar arranged to close the elongated groove. The elongated antenna structure of the 10 radio frequency identifier 102 is illustrated in figure 1e where elements of the antenna structure are denoted with references 105 and 106. The antenna structure can be e.g. a dipole antenna. As illustrated in figures 1d and 1 e, the opening ofthe elongated cavity faces downwards when the instrument cassette is in its operating position. As illustrated in figures 1d and 1 e, a part 120 of the body section for 15 mechanically supporting instruments is shaped to constitute the elongated cavity.
    This construction is a straightforward way to implement the elongated cavity for the radio frequency identifier 102. It is also possible that an elongated cavity has its opening on a side wall of the instrument cassette, i.e. the elongated cavity constitutes an elongated tubular room.
    It is, however, also possible that a radio frequency identifier of an instrument cassette according to an exemplifying embodiment does not comprise an elongated antenna structure ofthe kind shown in figure 1e. In this exemplifying case, the shape of a cavity for containing the radio frequency identifier may differ from the shape of the cavity 103 shown in figures 1d and 1e.
    Figures 2a, 2b, 2c, and 2d illustrate an instrument cassette 200 according to an exemplifying and non-limiting embodiment. The viewing directions related to figures 2a-2d are illustrated with a coordinate system 299. In the exemplifying situation shown in figure 2a, there is an instrument 211 in the instrument cassette 200.
    Figures 2b, 2c, and 2d illustrate a process for installing a radio frequency identifier 30 “RFID” 202 in the instrument cassette 200. The instrument cassette 200 comprises a body section 201 for holding instruments. As illustrated in figure 2b, the body
    20175681 prh 12 -07- 2017 section 201 has a cavity 203 for the radio frequency identifier 202. As can be understood based on figure 2b, the radio frequency identifier 202 is easy to install because the radio frequency identifier can be dropped to the cavity 203 and the cavity provides a mechanical support for the radio frequency identifier 202 during later phases of the assembly work. In this exemplifying case, the instrument cassette 200 comprises a closing element 204 that is suitable for closing the opening of the cavity, keeping the radio frequency identifier stationary with respect to the surfaces of the cavity, and constituting, together with the surfaces of the cavity 203, a room for the radio frequency identifier 202. The room for the radio frequency identifier 202 is advantageously a hermetically sealed room. In this exemplifying case, the cavity 203 is an elongated groove, the radio frequency identifier comprises an elongated antenna structure 205 and 206, and the closing element 205 is an elongated bar for closing the elongated groove. The closing element 204 is advantageously flexible, and the cavity 203 and the flexible closing element 204 are advantageously dimensioned so that the flexible closing element gets compressed in response to insertion in the cavity 203 in order to achieve an appropriate sealing.
    In the exemplifying installation process illustrated in figures 2b-2d, the closing element 204 is attached with glue to the surfaces of the cavity 203 in order to secure the fastening of the closing element 204. Arrows shown in figure 2c illustrate an exemplifying case where glue is added to the both ends and to the middle of the elongated cavity 203. A droplet of the glue is denoted with a reference 212. In cases where the glue is spread smoothly over contact surfaces of the closing element 204, the glue can act also as a seal for sealing the room containing the radio frequency identifier 202. In many cases, it is advantageous to use suitable primer with the glue. After the glue has been added, the closing element 204 can be pushed to the cavity 203. This is illustrated with an arrow shown in figure 2d. A spatula or an element having a flat surface can be used for ensuring that the closing element 204 positions itself properly.
    In the exemplifying instrument cassette 200 illustrated in figures 2a-2d, the closing element 204 is a pre-manufactured element that is installed in the body section 201 of the instrument cassette. It is also possible that a closing element of an instrument cassette according to an exemplifying embodiment is formed by material which has
    20175681 prh 12 -07- 2017 been cast in the opening of a cavity after a radio frequency identifier has been inserted in the cavity.
    Figures 3a and 3b illustrate an instrument cassette 300 according to an exemplifying and non-limiting embodiment. Figure 3a shows a top view of the instrument 5 cassette, and figure 3b shows a side view of the instrument cassette. Furthermore, figure 3b shows a view of a partial section taken along a line A-A shown in figure 3a. The section plane related to the partial section shown in figure 3b is parallel with the yz-plane of a coordinate system 399. The instrument cassette 300 comprises a body section 301 for holding instruments such as e.g. medical or dental hand 10 instruments. In the exemplifying situation shown in figures 3a and 3b, there are three exemplifying instruments in the instrument cassette 300. One of the exemplifying instruments is denoted with a reference 311. The exemplifying instrument cassette 300 comprises two sections 313 and 314 for the operational portions of the instruments. The instrument cassette 300 comprises cover elements 307 and 308 15 for covering the rooms for containing the operational portions of the instruments so as to prevent unintentional touching the operational portions of the instruments. In the exemplifying instrument cassette 300, the cover elements 307 and 308 are hinged to the body section 301. It is, however, also possible that a cover element or cover elements is/are shape locked or otherwise mechanically connected to a body 20 section of an instrument cassette according to an exemplifying embodiment. In the exemplifying situation shown in figures 3a and 3b, the cover element 308 is in an opened position.
    The instrument cassette 300 comprises a radio frequency identifier “RFID” that is readable from a distance away from the radio frequency identifier. In figure 3b, the 25 radio frequency identifier is denoted with a reference 302. In this exemplifying case, the radio frequency identifier 302 is located in a cavity 303 of the cover element 308.
    The instrument cassette 300 comprises a closing element 304 that closes the opening of the cavity 303 and constitutes, together with the surfaces of the cavity, a room for the radio frequency identifier 302. Advantageously, the cover element 308 30 is non-destructively detachable from the body section 301. In other words, the cover element 308 can removed without a need for irreversible material deformations. In this exemplifying case, the cover element 308 can be detached from the body section 301 by removing a hinge pin 330. As the cover element 308 is nondestructively detachable from the body section 301, it is straightforward to replace the cover element 308 with another cover element that is provided with another radio frequency identifier. Thus, the radio frequency identifier 302 can be easily replaced 5 with another radio frequency identifier.
    In the exemplifying instrument cassettes 100, 200, and 300 illustrated in figures 1a1e, 2a-2d, and 3a and 3b, the radio frequency identifier is located in a cavity constituted by the body section or in a cavity constituted by a cover element for preventing unintentional touching the operational portions of instruments. It is also 10 possible that a radio frequency identifier is located in a part of the instrument cassette that is neither the above-mentioned body section nor a cover element of the kind mentioned above. The part can be for example a module for containing a radio frequency identifier. The module can be attached to e.g. the body section with a suitable attaching arrangement. The attaching arrangement may comprise for 15 example a screw and/or it can be based on material elasticity and/or spring force so that the module is easy to remove and to replace with another module.
    The specific examples provided in the description given above should not be construed as limiting the scope and/or the applicability of the appended claims. Lists and groups of examples provided in the description given above are not exhaustive 20 unless otherwise explicitly stated.
