DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] As shown in the exemplary drawings for purposes of illustration, the present disclosure for an instrument tray indicator system is generally illustrated herein with respect to several embodiments, including with respect to the instrument tray indicator panels 20, 20′ in FIGS. 3-6, which may be used in connection with a recessed front panel 22 (FIG. 6) that may be integrated or otherwise used in connection with an instrument tray, such as a prior art instrument tray 24 illustrated in FIG. 1 or an alternative prior art instrument tray 26 illustrated in FIG. 2. While the instrument tray indicator panels 20, 20′ disclosed herein may be compatible with a wide range of instrument trays, the prior art instrument trays 24, 26 illustrated in FIGS. 1 and 2 are exemplary of the type of instrument trays compatible for use with the instrument tray indicator panels 20, 20′, and particularly for use in connection with orthopedic surgical procedures.

[0033] More specifically in this respect, FIG. 1 is a perspective view illustrating the prior art instrument tray 24 having a generally rectangular shape formed by a series of perforated upstanding sidewalls 28 formed from a rigid metal material that, together with a prior art recessed rear panel 30 and a prior art recessed front panel 32, form a protective interior 34 for storing one or more medical components therein, such as surgical instruments and/or implants, for use during a surgical procedure (e.g., orthopedic surgery). In the case of the prior art instrument tray 24, the protective interior 34 includes a series of rows, a first row 36, a second row 38, and a third row 40, for storing surgical instruments. For example, the first row 36 is illustrated in FIG. 1 having a series of differently sized inserts 42 secured within the protective interior 34 by way of a set of couplings designed to organize the inserts 42 stored therein by size. Accordingly, since the inserts 42 may be used during knee replacement surgery, the second row 38 and/or the third row 40 may also retain other knee replacement implant components or related surgical instruments that may assist the surgical team in performing orthopedic knee replacement surgery. Of course, similar to the first row 36 storing the series of differently sized inserts 42, the second row 38 and/or the third row 40 may each store common implant components varying in size. As a result, each of the rows 36, 38, 40 may retain a common set of knee implant components unique for each of the rows 36, 38, 40.

[0034] The implant components secured within the prior art instrument tray 30 illustrated in FIG. 1 may be enclosed within the protective interior 34 by a lid (not shown). Here, the lid may cooperate with each of the opposing perforated upstanding sidewalls 28 and the prior art recessed rear panel 30 and the prior art recessed front panel 32 to enclose therein the orthopedic components including, e.g., the aforementioned inserts 42. The lid may secure to the prior art instrument tray 42 by way of an externally located handle or clasp 46 coupled to or otherwise integrated with each of the prior art recessed rear panel 30 and/or the prior art recessed front panel 32. As such, when the lid encloses the prior art instrument tray 24, it may be difficult and/or impossible (especially, e.g., when the prior art instrument tray 24 is enclosed with sterile wrapping) to identify the orthopedic components therein, despite the fact that the upstanding sidewalls 28 and/or the prior art recessed rear panel 30 and/or the prior art recessed front panel 32 may include a series of perforations 48 therein, as generally illustrated throughout in each of FIGS. 1 and 2. In fact, the only indicia illustrated with respect to the prior art recessed front panel 32 is a set of logo indicia 50 imparted to a generally planar non-perforated surface 52 thereof that is otherwise unreadable when the prior art instrument tray 24 is enclosed with sterile wrapping.

[0035] As is known in the art, the prior art recessed front panel 32 may couple to each of the opposing upstanding perforated sidewalls 28 by a set of rivets 54 illustrated in FIG. 1, and as more specifically illustrated in the enlarged front view of FIG. 2 with respect to the alternative prior art instrument tray 26 and an alternative recessed front panel 56. Similar to the prior art recessed front panel 32 illustrated with respect to FIG. 1, the alternative recessed front panel 56 also includes the perforations 48 formed therein, the clasp 46 for securing the lid over the protective interior 34, and the logo indicia 50 formed within the planar non-perforated surface 52. Although, the alternative prior art recessed front panel 56 illustrated with respect to FIG. 2 also includes a protruding front indicia 58 in the form of a single linear line 58. Such protruding front indicium in the form of the single linear line 58 or the like has been used with respect to prior art devices to indicate the tray number, in this case a first tray. But, even to the extent that such protruding front indicia 58 can be identified through sterile wrapping or with latex gloves prior to or during surgery, such protruding front indicium 58 can be used for nothing more than identifying the number of the tray; and certainly not for identifying any of the surgical components within the tray. Moreover, the protruding front indicia 58 is also formed integrally with the alternative recessed front panel 56, as illustrated in FIG. 2. Thus, to the extent the couplings 44 within the protective interior 34 change, the protruding front indicia 58 does not and cannot otherwise change by way of the fact that it is formed integral with the metal material forming the alternative recessed front panel 56.

[0036] As such, FIGS. 3-5 illustrate a pair of exemplary embodiments of the instrument tray indicator panel 20, 20′ having a set of unique component identifying indicia 60 thereon. Specifically with respect to FIG. 3, one embodiment of the instrument tray indicator panel 20 is illustrated having three of the unique component identifying indicia 60, 60′, 60″ formed thereon, wherein the unique component identifying indicia 60 is in the form of an enlarged circle located in a bottom left hard corner of the instrument tray indicator panel 20, the unique component identifying indicia 60′ is in the form of an uppercase “P” positioned central within the instrument tray indicator panel 20, and the unique component identifying indicia 60″ is in the form of a single relatively smaller circle located in a bottom right hand corner of the instrument tray indicator panel 20. Here, and as best illustrated in the top plan view of FIG. 5, each of the unique component identifying indicia 60, 60′, 60″ generally protrude outwardly from a base surface 62 of the instrument tray indicator panel 20. For example, one or more of the identifying indicia 60, 60′, 60″ may protrude outwardly from the base surface 62 between 0.05 inches and 1.0 inches, and specifically by about 0.25 inches to 0.3825 inches. Alternatively, one or more of the identifying indicia 60, 60′, 60″ may protrude outwardly from the base surface 62 between 0.05 inches and 1.0 inches, and specifically by about 0.25 inches to 0.3825 inches, relative to the panel to which the identifying indicia 60, 60′, 60″ are formed or attach (i.e., in this latter embodiment, the thickness of the base surface 62 may be taken into account when considering the aggregate distance the identifying indicia 60, 60′, 60″ protrude). In another example, the depth of the recessed front panel 32 or the alternative recessed front panel 56 may be about 0.75 inches and the aggregate thickness of the identifying indicia 60, 60′, 60″ may not exceed 0.75 inches such that the identifying indicia 60, 60′, 60″ may provide tactile feedback through sterile wrap covering the tray when tented over the recessed front panel 32 or over the alternative recessed front panel 56 without damaging (e.g., penetrating) the sterile wrap. In this embodiment, the identifying indicia 60, 60′, 60″ effectively remain within the enclave of the recessed front panel 32 or the alternative recessed front panel 56 so as to be positioned in non-contact relation relative to the sterile wrap tented over the recessed front panel 32 or the alternative recessed front panel 56.

[0037] Accordingly, each of the unique component identifying indicia 60, 60′, 60″ may be used to uniquely identify the orthopedic implant components stored within each of the respective rows 36, 38, 40 by way of being aligned therewith immediately behind each of the unique component identifying indicia 60, 60′, 60″ when the instrument tray indicator panel 20 is attached to the recessed front panel 22 as illustrated, e.g., in FIG. 6. In other words, the identifying indicia 60 may be designed to provide an indication of the surgical instruments within the row 36, the identifying indicia 60′ may be designed to provide an indication of the surgical instruments within the row 38, and the identifying indicia 60″ may be designed to provide an indication of the surgical instruments within the row 40.

[0038] Of course, as discussed in more detail below, the instrument tray indicator panel 20 may include different unique component identifying indicia 60, alternatively, in addition, or in place of those identified above with respect to the relatively large circle formed within a lower left-hand portion of the base surface 62 identified with respect to reference numeral 60, the uppercase “P” formed within the middle of the base surface 62 and identified with respect to reference numeral 60′, and/or the single relatively smaller circle located in a bottom right hand corner of the instrument tray indicator panel 20 and identified with respect to reference numeral 60″.

[0039] For example, as illustrated in FIG. 4, the alternative instrument tray indicator panel 20′ may include a pair of the unique component identifying indicial 60″, 60′″ in the form of a pair of the relatively smaller circles formed from a right side 64 of the instrument tray indicator panel 20′. Here, the pair of unique component identifying indicia 60″, 60′″ illustrated in FIG. 4 may be used to identify different orthopedic implant components within the third row 40 stored within the protective interior 34 thereof. In another alternative embodiment, the stacked relationship of the unique component identifying indicia 60″, 60′″ may be used to identify certain implant components within the front half of the third row 40 of the instrument tray (e.g., by way of the unique component identifying indicia 60″) and a different set of components within the back half of the third row 40 of the instrument tray (e.g., by way of the unique identifying indicia 60′″). In other words, this third row 40 may be partitioned into two columns, where the indicia 60″ identifies the first set of components within the first column of the third row 40 and the indicia 60′″ identifies the second (and different) set of components within the second column of the third row 40. This may be especially so when the shape of the unique component identifying indicia 60″ differs from that of the unique component identifying indicia 60′″. As such, the identifying indicia 60 may be positioned to provide tactile feedback in a manner where specific components can be identified within specific sectors of a grid matrix identified by row and column number. The grid matrix may thus earmark specific locations for instruments within the tray, and the indicia 60 may be arranged in a comparable matrix providing external tactile feedback so one can identify specific components within each sector of the grid matrix within the tray through externally applied sterile wrap.

[0040] In addition to, or in an alternative of, the unique identifying indicia may be designed to convey information broader than the specific type of components within the tray. Examples here might include conveying information regarding the type of material the components are made from (e.g., cobalt chrome, titanium, etc.), the type of system (e.g., a total knee replacement system or revision knee system), type of joint (e.g., knee, hip, shoulder, etc.), order the tray should be opened, etc. Moreover, the relative location of the indicia may also provide guidance as to whether the indicia are designed to provide broader information or component specific information. In one embodiment, e.g., indicia placed within a top portion of a tray or panel may be designed to convey general information (e.g., component material or system type), while indicia placed along a lower portion of the tray or panel may be designed to convey more specific information (e.g., components being stored within the protective interior 34 of the tray).

[0041] Additionally, as illustrated best in FIGS. 3 and 4, the instrument tray indicator panel 20, 20′ may include a set of four mounting apertures 66 in the form of outwardly extending eyelets. Although, in an alternative embodiment, the mounting apertures may be formed as part of the base surface 62 of the instrument tray indicator panel 20 such that the mounting apertures 66 do not outwardly extend therefrom. In either embodiment, the mounting apertures 66 may be of a size and shape commensurate with the perforations 48 formed within the front panel 22 to permit attachment thereto, such as by way of the aforementioned rivets 54 best illustrated in FIG. 6. The rivets 54 may secure the instrument tray indicator panel 20 thereto substantially centered within the recessed portion of the front panel 22 and underneath the planar non-perforated surface 52 where the logo indicia 50 (FIGS. 1 and 2) may be located. In one embodiment, the rivets 54 may permanently attach the instrument tray indicator panel 20 to the front panel 22. Alternatively, the rivets 54, or other connectors as may be known in the art, may be configured to selectively engage the instrument tray indicator panel 20 to the front panel 22. In this latter embodiment, the instrument tray indicator panel 20 may be removed and/or attached to different instrument trays, depending on the contents therein. This latter option may provide more flexibility in identifying the surgical instruments stored by any given tray based on the needs of a particular surgery. In other words, the instrument tray need not necessarily be a one size fits all for purposes of identifying the contents therein by way of the instrument tray indicator panel 20.

[0042] The unique component identifying indicia 60 of the instrument tray indicator panels 20, 20′ may be machined from a variety of materials, such as aluminum. Once manufactured, such an aluminum instrument tray indicator panel 20, 20′ may attach to the front panel 22 in the manner illustrated in FIG. 6. In this respect, the embossed symbols forming the unique component identifying indicia 60 may be formed at a height that allows the shape of the identifying indicia 60 to be uniquely identified through sterile wrap and while the medical technician is also wearing latex gloves.

[0043] In one embodiment, the unique component identifying indicia 60 may be derived from basic geometric shapes such as the circles as illustrated in FIGS. 3-7, squares, rectangles, triangles, etc. Alternatively, or in addition to, the unique component identifying indicia 60 may be formed to represent alphanumeric characters, such as capital or lowercase letters of the alphabet, numbers, shapes, etc. In this respect, each unique component identifying indicia 60 should be able to convey basic information regarding the contents of the instrument tray through tactile sensation and location, especially for users wearing latex gloves. It may be particularly useful to use the unique component identifying indicia 60 formed into the instrument tray indicator panel 20 to convey location and surgical instrument component information therein when the instrument tray is sealed in sterile wrapping.

[0044] In one example, the unique component identifying indicia 60 may correlate basic geometric shapes or alphanumeric characters with certain implantable joint components the indicia 60 are designed to represent. For example, FIG. 7 illustrates correlating an implantable femoral component 68 with that of a geometric shape that includes an enlarged circle indicium 70. Alternatively, FIG. 8 illustrates correlation of a femoral stem 72 with that of a geometric shape that includes a rectangular geometric shape indicium 74. In additional alternative embodiments, FIG. 9 illustrates correlating a capital letter “P” 76 with that of a P-shaped indicium 78; and FIG. 10 illustrates correlating a lower case “b” 80 with that of a b-shaped indicium 82. In each instance, the enlarged circle indicium 70, the rectangular geometric shape indicium 74, the P-shaped indicium 78, and/or the b-shaped indicium 82 are either geometric shapes or alphanumeric characters that protrude out from the base surface 62 of the instrument tray indicator panel 20, 20′ to provide tactile feedback or sensation in addition to a visual representation of the type of joint component stored within an instrument tray, even when the instrument tray may be enclosed by a lid or otherwise wrapped such that the instruments therein are not directly visible. Furthermore, any of the identifying indicia 60, 60′, 60″, 60′″ and/or indicium 70, 74, 78, 82 may couple directly to the tray (e.g., without the indicator panel 20, 20′) and may further include an edge break that helps prevent the indicia 60, 60′, 60″, 60′″ and/or indicium 70, 74, 78, 82 from tearing, poking through, or otherwise damaging the sterile wrap. The edge break may be a chamfered edge, a filleted edge, a radiused edge, or a beveled edge.

[0045] In alternative embodiments, the instrument tray indicator panel 20 and/or the indicia 60 may couple to the instrument tray at different locations (e.g., not necessarily below the planar non-perforated surface 52), such as anywhere along either of the upstanding perforated sidewalls 28, along the perforated rear panel 30, on the lid, or even on the bottom of the instrument tray panel. Attaching additional or alternative instrument tray indicator panels 20 and/or indicia 60 in this manner may increase the level of information conveyed to a medical technician regarding the contents of the instrument tray; and may allow for more specific and unique identification of surgical instruments stored within any surgical tray.

[0046] Additionally, while the unique component identifying indicia 60 disclosed herein generally protrude out from the base surface 62 of the instrument tray indicator panel 20, 20′, in alternative embodiments, the unique component identifying indicia 60 may be formed into the base surface 62, thereby forming a geometric or alphanumeric-shaped indentation, aperture, or cutout therein. The same is true with respect to forming any of the identifying indicia 60 and/or the indicium 70 as a shaped indentation, aperture or cutout in any of the perforated sidewalls 28, the recessed rear panel 30, and/or the recessed front panel 32 such that the three-dimensional structure of the indicial 60 and/or the indicium 70 may provide tactile feedback through sterile wrapping by way of tracing the indentation, aperture, or cutout within the panel 20, 20′, and/or the respective perforated sidewall 28, the recessed rear panel 30, or the recessed front panel 32. Here, the identifying indicia 60 and/or the indicium 70 that form a geometric or alphanumeric-shaped indentation, aperture, or cutout in any of the panels 20, 20, the perforated sidewall 28, the recessed rear panel 30, or the recessed front panel 32 may have a thickness of about 0.05 inches to 1.0 inches, and more specifically from about 0.25 inches to 0.3825 inches. Furthermore, the geometric or alphanumeric-shaped indentation, aperture, or cutout may include the aforementioned edge break, which may be a chamfered edge, a filleted edge, a radiused edge, or a beveled edge, albeit internally along the indentation, aperture, or cutout.

[0047] Although several embodiments have been described in detail for purposes of illustration, various modifications may be made without departing from the scope and spirit of the invention. Accordingly, the invention is not to be limited, except as by the appended claims.
