Description

Technical Field

[0001] The present invention relates to a perforated instrument holder for medical instruments, in particular for surgical instruments and / or implants for supplying sterile items in the medical field, in particular in operating rooms, the perforated instrument holder comprising a perforated holder support structure having a plurality of perforated holder openings; a top side facing the instrument of the perforated holder support structure, and a bottom side facing away from the instrument; and at least one device that can be positioned from the top side of the perforated holder support structure at various selectable positions on the top side for storing and preferably for retaining one or more instruments in a given arrangement on the perforated instrument holder, wherein the device comprises a base portion, and an instrument-carrying portion that can be releasably fastened to the base portion, wherein the base portion can be releasably fixed to the perforated holder support structure. Background Art

[0002] Such perforated instrument holders, which are usually designed as perforated instrument baskets or perforated holder inserts for sterile article containers, play an important role in the so-called sterile article circulation of medical and especially surgical instruments, since they receive the instruments to be sterilized during sterilization and afterwards during transport to sterile article storage facilities and from there to the place of use, especially the operating room. For this reason, so-called organizational systems have been proposed for perforated instrument holders of the type mentioned above, for keeping the instruments on the perforated instrument holders in a predetermined position and arrangement until they are removed by medical personnel just before they are used. Previously known devices for storing one or more instruments on perforated instrument holders can be fastened to the perforated instrument holder or its perforated holder support structure by means of a screw connection, which is considered complicated, or inserted through the perforated holder support structure from the bottom side of the perforated holder support structure through the perforated holder opening or other specially designed openings, so that they protrude upwards on the top side of the perforated instrument holder in order to be able to store the instruments there. Both of these mean that the holding devices are assembled to some extent on both sides of the perforated instrument holder. The holding device or devices can therefore only be arranged on the perforated instrument holder support structure at the beginning of loading the instrument, because the perforated instrument holder must be tilted and turned over for this purpose. Mounting elements arranged on the bottom side of the perforated instrument holder have also proven to be destructive; in particular, they can cause wear, damage to the support surface or, if not evenly distributed, also to the perforated instrument holder swinging on the support surface.

[0003] US2020 / 0030049A1 discloses a carrier for items to be sterilized, wherein a column with a hook-shaped portion clips into a slot on the carrier. Partial elements can then be inserted into the column. DE 697 32 986T2 discloses an instrument holder, wherein a body made of silicone and a stainless steel support frame with ribs and locking claws are provided. Summary of the invention

[0004] Proceeding from this, the object solved by the present invention is to make a perforated instrument holder of the type mentioned at the outset more user-friendly for a releasable arrangement of a device for storing one or more instruments, which device can be releasably fastened to a perforated holder support structure without the use of tools.

[0005] This object is achieved according to the invention in a perforated instrument holder of the aforementioned type, wherein a base part has: a main limb, which can be placed against the top side of the perforated holder support structure; and two opposite side limbs, which adjoin the main limb laterally, wherein starting from each of the side limbs of the base part, at least one flexible tongue and preferably at least two flexible tongues are formed on one or both sides, extending from the side limb of the base part in the direction of the perforated holder support structure and being elastically deflectable relative to the side limbs so that the at least one flexible tongue engages in the top side of the perforated holder support structure. In a manner behind the perforated holder opening, the base portion can be positioned with its main limb on the top side of the perforated holder support structure, and wherein merely by applying a compressive force on the base portion in the direction of the top side of the perforated holder support structure, the relative flexible tongue then deflects and automatically penetrates into another perforated holder opening, where the flexible tongue latches with the edge area delimiting the perforated holder opening, so that the base portion can be fastened to the perforated holder support structure for its intended purpose without the use of tools and in a non-detachable manner.

[0006] Therefore, it is proposed according to the invention that the base part of the holding device is designed to have a flexible tongue extending downward (especially obliquely downward) in the direction of the perforated holder support structure, by means of which the base part can be hooked into one or more perforated holder openings from the top side of the perforated holder support structure by means of a flexible tongue on one side of the base part, and then only by pressing on the base part in the direction of the top side of the perforated holder support structure, the flexible tongue provided on the opposite side limb of the base part deflects and is brought into a position in which it engages behind the perforated holder support structure. In this way, it is conceivable that each base part is arranged and assembled on the perforated instrument holder without the use of tools. After this, the instrument carrying part can then be releasably arranged on the base part, for example by pushing or placing it on the base part in the direction of the plane of the perforated holder support structure, or by attaching it to the base part in another way with force fit or shape fit. However, it is also conceivable that the base part together with an instrument carrying part already arranged on the base part can be releasably fixed to the perforated instrument holder in the manner described above.

[0007] For economical manufacturability and stability of the device, it has proven to be advantageous that the base part is a bent sheet metal part and that the flexible tongue is cut out of said bent sheet metal part. In this case, the base part including its flexible tongue can be formed from a flat metal material part by a punching and bending process. The curved corrugations between the main limb and the two laterally adjacent side limbs give the base part a high torsional stability, even for thinner wall thicknesses of the base part, in particular 0.2 to 1.0 mm, in particular 0.25 to 0.8 mm, and in particular 0.3 to 0.5 mm. Furthermore, a further corrugation can be provided at the top free end of the side limb, preferably an inward corrugation, which further increases the torsional rigidity and can also limit the sliding seat socket for the instrument carrying part.

[0008] Furthermore, it has proven advantageous to have a flexible tongue cut from the side limb and the main limb. In such a case, the flexible tongue can be long enough so that it can be engaged in the perforated holder opening of the perforated instrument holder without the need for an additional retaining extension, and the rear engagement element does not need to be provided separately or attached to the free end of the flexible tongue.

[0009] In order to reliably fix the device or its base part to the perforated instrument holder, it has proven to be advantageous if the free end of preferably each of the flexible tongues is designed or shaped to form a rear engagement area or rear engagement bead. Thus, each flexible tongue can reach a form-fitting rear engagement position with an edge area of ​​the perforated holder support structure, which delimits the corresponding perforated holder opening, and can also be reliably held there under the effect of the resilience of the flexible tongue.

[0010] It has also proven advantageous if the free end of preferably each of the flexible tongues forms an angle of more than 90°, preferably at least 100°, preferably at least 110° with the longitudinal extension of the flexible tongue and thus engages behind an edge region delimiting the apertured holder opening.

[0011] In order to enable the operator to secure the base part to the perforated holder support structure in a simple, reliable and convenient manner, it has proven to be advantageous if the free end of preferably each of the flexible tongues forms an arc-starting slope of the corresponding flexible tongue, which, when the base part is pressed in the direction of the top side of the perforated holder support structure, hits an edge area delimiting the perforated holder opening and deflects so as to latch with the edge area into a rear engagement position.

[0012] As already mentioned at the outset, it has proven to be convenient if the base part forms a latching receptacle or a sliding seat receptacle for the instrument carrying part, wherein the sliding seat receptacle is delimited laterally by two side limbs of the base part and at the bottom by a main limb. In addition, one or preferably both side limbs can have an inwardly projecting portion in their top edge region, in particular by folding over the side limbs, and thereby delimit the sliding seat receptacle at the top.

[0013] According to one embodiment, the instrument-carrying part, which can be releasably fastened to the base part, is a polymer plastic part, which preferably comprises silicone or consists of silicone. Although the instrument-carrying part is dimensionally stable, it conveniently has a flexibly deflectable holding area for the instrument. The instrument-carrying part is conveniently individually adapted to the instrument to be stored and for this purpose comprises a holding structure, in particular a holding arm, and, if necessary, a recess and a centering bevel for placing the instrument and, in particular, clamping it in the instrument.

[0014] In principle, the perforated instrument holder can have any perforated surface structure, as long as the perforated holder openings are arranged periodically and the arrangement and design can therefore be designed according to the distance between the perforated holder openings, in particular maintaining the distance between the tongues. For the production of perforated surface structures that are opened primarily for sterilization purposes, it has proven to be advantageous for the perforated instrument holder to have a perforated holder support structure with a perforated holder opening that is particularly rectangular and preferably square, which is delimited by a connecting piece that is narrower than the side length of the rectangular shape or than the maximum dimension of the perforated holder opening. Specifically, the width of the connecting piece is not more than 30%, in particular not more than 20%, of the maximum dimension of the perforated holder opening, regardless of whether they are rectangular or not.

[0015] It may also prove advantageous if, when viewing the top side from above, the perforated instrument holder is rectangular with corresponding longitudinal and transverse directions, and the connecting piece delimiting the perforated holder opening also extends at an inclination of 45° to the longitudinal or transverse direction. In such a case, the perforated holder opening may also extend at an inclination of 45° to the longitudinal or transverse direction of the perforated instrument holder. However, if the base part is then aligned in the longitudinal or transverse direction, then to some extent the resilience of the flexible tongues leads to self-centering of the relevant flexible tongue in the corner region of the relevant perforated holder opening.

[0016] Furthermore, it can prove advantageous if the perforated instrument holder comprises a three-dimensionally constructed, in particular corrugated, perforated holder support structure. In this case, the base part can be arranged and fastened in the high points or peaks of the perforated holder support structure, wherein the base part does not necessarily have to rest completely on these high points or peaks of the perforated holder support structure, but it is conceivable that the perforated holder support structure engages with its high points or peaks in recesses in the main limbs of the base part.

[0017] In a development of this concept, it has proven advantageous to form a recessed portion in the base part, into which the perforated holder support structure can engage by means of the raised portion, so that the position of the base part on the perforated holder support structure can be further stabilized.

[0018] In the case of a three-dimensional configuration, in particular a corrugated perforated holder support structure, the flexible tongue engaging behind the perforated holder opening or its rear engaging end is also arranged on the bottom side, but approximately in the region of the raised portion of the perforated holder support structure and thus at a distance from the supporting surface of the perforated instrument holder. This safely prevents any wear-induced strains on the supporting surface caused by the free end of the flexible tongue.

[0019] In a preferred embodiment, the perforated instrument holder including its perforated holder support structure can be formed from a flat metal material, in particular from a metal sheet, and can be manufactured in particular by cutting, punching and bending processes, in particular using laser cutting techniques. In this way, the material thickness of the perforated holder support structure can remain constant over its extension, in particular over the entire bottom area of ​​the perforated basket. In principle, however, a braided perforated holder support structure is also conceivable and sometimes advantageous.

[0020] For the above-mentioned self-centering of the flexible tongue in the corner area of ​​the perforated holder opening, it has proven to be advantageous that the distance between two adjacent flexible tongues of the side limbs corresponds to the distance between the two intersection points of the connecting parts delimiting the perforated holder opening, or is twice or an integer multiple thereof, and the flexible tongue can thus be automatically positioned in the corresponding corner area of ​​the perforated holder opening.

[0021] Furthermore, protection is claimed for a release device which is adapted to a base part and whose flexible tongues are as a component of a perforated instrument holder or as an accessory, which can be placed from the inside through an opening in the base part, against one or more flexible tongues in the area of ​​the side limbs, and which can thus be deflected from their rear engaged position so that the base part can be released from its position engaged behind the perforated instrument holder.

[0022] As already mentioned at the outset, the perforated instrument holder can be used as a perforated instrument basket or as an insert for a perforated instrument basket or instrument container.

[0023] As part of an organizational system for perforated instrument holders of the type discussed herein and according to the invention, protection is also claimed for a device for storing and preferably for holding one or more medical instruments, in particular surgical instruments, in a defined arrangement on a perforated instrument holder, wherein the device comprises a base portion and an instrument-carrying portion which can be held to the base portion, wherein the base portion can be releasably fixed to the perforated instrument holder, the device being characterized in that the base portion has a main limb which can be placed against a top side, and two opposing side limbs adjoining the main limb at the sides, and wherein proceeding from each of the side limbs of the base portion, at least one and preferably two flexible tongues are formed on one or both sides, It extends from the side limbs of the base part in the direction of the perforated holder support structure and can be elastically deflected relative to the side limbs, so that the base part can be positioned with its main limb on the top side of the perforated holder support structure by means of at least one flexible tongue engaging behind the perforated holder opening, and wherein only by applying a compressive force on the base part in the direction of the top side of the perforated holder support structure, the relative flexible tongue then deflects and automatically penetrates into the other perforated holder opening, in which the relative flexible tongue latches with the edge area delimiting the perforated holder opening, so that the base part can be fastened to the perforated holder support structure for its intended use without the use of tools and in a non-detachable manner.

[0024] Furthermore, protection is claimed for a device for storing and preferably for holding one or more medical instruments, in particular surgical instruments and / or implants, in a defined arrangement on a perforated instrument holder having the features of claim 17. Advantageous developments are described in claims 18 to 21 .

[0025] Furthermore, protection is claimed for a device having the features of claim 16 or claim 17 which additionally has the features of claims 2 to 13 .

[0026] Further features, details and advantages of the invention can be found in the dependent claims, in the drawings and in the following description of preferred embodiments of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The figure shows an embodiment of a perforated instrument holder 2 for medical, especially surgical instruments according to the present invention, which is used to supply sterile items in the medical field. The perforated instrument holder 2 includes a perforated holder support structure 4, which has a plurality of perforated holder openings 6, and a device 8 for storing and preferably holding instruments (not shown in the figure) during the sterile article circulation. The device 8 includes a base portion 10, and an instrument bearing portion 12 that can be releasably fastened to the base portion. The base portion 10 can be releasably fastened to the perforated holder support structure 4 in a manner described in more detail below. The perforated holder support structure 4 has a top side 14 facing the device 8 and the instrument (not shown), and a lower side 16 facing away from the device 8 and the instrument.

[0034] In the exemplary case presented here, the perforated holder support structure 4 is corrugated and thus has a three-dimensional wave structure. The perforated holder support structure 4 is formed, for example, from two groups, each group consisting of a plurality of parallel connecting elements 18, wherein the connecting elements 18 of one group extend at right angles to the connecting elements 18 of the other group, so that they delimit the perforated holder opening 6. The perforated holder support structure 4 consisting of the connecting elements 18 is initially flat and subsequently forms a corrugated structure. Despite the three-dimensional structure, the perforated holder opening 6 can, for example, in the case of the present invention be described as being substantially square (compare Figure 4b , 4c ), i.e. they have a square shape when projected vertically onto the base surface of the perforated holder support structure 4.

[0035] Figure 2 and other figures show the shape and design of the base part 10. In the exemplary case shown here, the base part is formed from a flat sheet metal material which is formed into a plurality of sheets by cutting, punching or bending processes. Figure 2 . The base part 10 comprises: a main limb 20, which can be placed against the top side 14 of the perforated holder support structure 4; and two opposite side limbs 22, 24, which adjoin the main limb at the side and which, in the exemplary case shown, roughly delimit a U-shape, which narrows slightly towards the top when viewed in the direction of the arrow 26. In addition, the side limbs 22, 24 have inwardly curved edge areas 28 and 30, respectively, at their top free ends. It can also be seen that, starting from each of the side limbs 22, 24, two flexible tongues 32, 34 are formed on each side. These flexible tongues 32, 34 are cut out of the material of the previously flat material part by punching cuts and thus leave recessed portions 35 in the main limb 20 of the base part 10 and in the side limbs 32, 34. The flexible tongues are bent outwardly so that they extend obliquely downward at an acute angle from the top region of the side limbs 22, 24 in the direction of the perforated holder support structure 4 and can be elastically deflected relative to the side limbs 22, 24. Each flexible tongue, 34 is bent inwardly at its free end and forms a rear engagement region 36, with which the relevant flexible tongue 32, 34 can be engaged in the perforated holder opening 6 and form a positively locking connection with the edge region delimiting the perforated holder opening 6, i.e. with the connecting piece 18 of the perforated holder support structure 4. This reference Figure 3a to Figure 3c To explain: Figure 3a An example of a three-dimensional corrugated perforated holder support structure 4 and a base portion 10 with its flexible tongues 32, 34 is shown. Figure 3a As can be seen in FIG. 1 , the base portion 10 is slightly inclined relative to the plane of the perforated holder support structure 4 so that Figure 3aThe flexible tongue 32 of the side limb 22 shown on the left in the middle engages in two adjacent perforated holder openings 6 in the region of the wave crests of the perforated holder support structure 4 and is hooked with the connecting piece 18 by means of each of its rear engagement regions 36. From this assembled situation, only Figure 3b The compressive force in the direction of the arrow 38 shown in FIG. 1 now needs to be applied to the base portion 10 or the other side limb 24 in the direction of the perforated holder support structure 4, so that the opposite flexible tongue 34 hits the connecting piece 18 with its rear engaging end area 36 and is thereby deflected outwards and finally reaches Figure 3c In the rear engagement situation shown in the figure, the flexible tongue 34 rebounds inwardly after being engaged in the two perforated holder openings, and thus presents an assembly position that prevents falling off on the perforated holder support structure 4. In this assembly position, the base part 10 is placed to some extent with its main limb 20 in the area of ​​the raised part of the perforated holder support structure 4, and is arranged parallel to the plane of the perforated holder support structure 4 again. However, in the example embodiment shown, the base part is not placed just on the top of the high point of the raised part of the perforated holder support structure 4, but relatively high on the connector to that. The high point or vertex of the raised part pierces into the recessed part 35 in the base part, and the recessed part is produced here by the flexible tongue 32 that is cut. If the base part is long and extends over multiple raised parts of the perforated holder support structure, multiple such recessed parts can be formed in the base part to allow the high point or vertex of the raised part to pierce or engage in this way.

[0036] In an embodiment not shown, if the flexible tongue is not adapted to two perforated holder openings of a perforated basket arranged one after the other, but is designed to engage in perforated holder openings that are further apart from each other, the base portion can be provided with one or more additional recessed portions, into which the high point or vertex of the central raised portion of the three-dimensionally constructed perforated body structure can penetrate. This penetration reduces the installation height of the base portion above the perforated holder support structure and displaces its position relative to the side (i.e., in Figure 5 ) because the flexible tongue also has a certain degree of elasticity in the lateral direction, which is not required in this direction itself.

[0037] Ideally, the surface of the apex of the raised portion in the corrugated perforated holder support structure and the surface of the main limb of the base portion lie in one plane; this allows for maximum reduction in the installed height of the base portion and still allows the instrument carrying portion to be inserted without hitting the apex of the raised portion. For stability and assembly security of the instrument carrying portion, it is particularly advantageous for its bottom side to rest on or abut against the top side of the main limb of the base portion.

[0038] Figures 4a to 4cis a further view of the base part 10 assembled on the perforated holder support structure 4 .

[0039] exist Figure 4c In the figure, arrow 40 shows the insertion of Figure 3a and 3b 3, how the flexible tongues 32, 34 are guided in a self-centering manner along the connecting piece 18 into the stable assembly position shown, thanks to their resilience, after being inserted into the perforated holder opening of the three-dimensional corrugated perforated holder support structure 4 shown in FIG. The free ends of the flexible tongues 32, 34 are preferably rounded or chamfered, because this reduces the necessary deflection of the flexible tongues 32, 34 when sliding on the connecting piece of the corrugated perforated holder support structure extending obliquely thereto. This makes it possible to work in conjunction with a harder or more powerful spring leg and reduces the risk of damage to the user's gloves or hands during assembly, without having a significant impact on the stability of the anchoring of the base part to the perforated holder support structure.

[0040] Figure 5 The finished holding device 8 is shown, whereby the instrument-carrying part 12 of the holding device can be pushed onto the base part 10 in the direction of the arrow 42 parallel to the plane of the perforated holder support structure 4. With the aid of its top inwardly bent edge regions 28, 30, the base part 10 forms a dovetail-shaped sliding seat socket for supplementing the instrument-carrying part 12. However, it should be explicitly mentioned that the instrument-carrying part 12 and the base part 10 can also be assembled together in another way and releasably fastened to each other. In particular, it is also conceivable to fix the base part 10 with the preassembled instrument-carrying part 12 against the perforated holder support structure 4 in the manner described.

[0041] However, in order to release the holding device 8 or the base part 10 from the perforated holder support structure 4, in the exemplary case shown, it is convenient to release the instrument carrying part 12 from the still assembled base part 10 so that it can be removed by means of Figure 6a and 6b The release device 44 shown in FIG. 4 is used to approach the flexible tongues 32, 34 so that the flexible tongues 32, 34 are in the Figure 6b4, so that they are released from the situation in which they are engaged behind the connection piece 18 of the perforated holder support structure 4, and the base part 10 can initially be pivoted upward away from the perforated holder support structure 4, and then moved to the other side opposite to the arrow 46, so that the flexible tongue 34 on the opposite side limb 24 is also released from its rear engagement situation, and finally the base part 10 can be completely removed. Alternatively, for a corresponding design of the length and pretension of the flexible tongues 32, 34, it is however also conceivable in principle that, without the use of tools, with or without the device carrying part 12, the base part 10 is moved to the left in the direction of the arrow 46, so that Figure 6b The flexible tongues 32 shown on the left in the figure are released from the position in which they are engaged behind the connector 18 and the base portion can then be pivoted upwards and removed from the perforated holder support structure 4 to the opposite side without the use of tools.
