Description

Technical Field

[0001] This invention relates to perforated instrument holders for medical devices, particularly for surgical instruments and / or implants used in the medical field, especially in operating rooms, to supply sterile articles. The perforated instrument holder includes a perforated instrument holder support structure having a plurality of perforated instrument openings; a top side facing the instrument on the perforated instrument 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 instrument holder support structure at various selectable locations on the top side for storing and preferably securing one or more instruments in a predetermined arrangement on the perforated instrument holder, wherein the device includes a base portion and an instrument carrying portion releasably fastened to the base portion, wherein the base portion can be releasably fixed to the perforated instrument holder support structure. Background Technology

[0002] Such perforated instrument holders are typically designed as perforated instrument baskets or perforated holder inserts for sterile article containers, playing a crucial role in the so-called sterile article cycle of medical, and especially surgical, instruments, as they receive instruments to be sterilized during sterilization and subsequently during transport to sterile article storage facilities and from there to the place of use (especially the operating room). For this purpose, so-called tissue systems have been proposed for perforated instrument holders of the types mentioned above, for holding instruments in a predetermined position and arrangement on the perforated instrument holder until they are removed by medical personnel immediately before use. Previously known devices for storing one or more instruments on a perforated instrument holder may be secured to the perforated instrument holder or its perforated instrument holder support structure by means of threaded connections, which are considered complex, or inserted through the perforated instrument holder opening or other specially designed openings from the bottom side of the perforated instrument holder support structure, such that they protrude upwards from the top side of the perforated instrument holder to allow the instruments to be stored there. Both of these imply that the retaining devices are assembled to some extent on both sides of the perforated instrument holder. The one or more retaining devices can therefore be configured on the perforated instrument holder support structure only at the start of instrument loading, as the perforated instrument holder must be tilted and flipped for this purpose. Mounting elements arranged on the bottom side of the perforated instrument holder have also proven destructive; specifically, they can cause wear and damage to the support surface, or, if not evenly distributed, to the perforated instrument holder swinging on the support surface.

[0003] US2020 / 0030049A1 discloses a carrier for articles to be sterilized, wherein a column with a hook-like portion is clamped into a slot on the carrier. Certain components can then be inserted into said column. DE 697 32 986T2 discloses an instrument holder, wherein a body made of silicone resin is provided, and a stainless steel support frame having ribs and locking claws. Summary of the Invention

[0004] Therefore, the objective of this invention is to provide a more user-friendly perforated instrument holder of the type mentioned at the beginning for a releasable arrangement of a device for storing one or more instruments, wherein the device can be releasably secured to the perforated holder support structure without the use of tools.

[0005] This objective is achieved according to the invention in a perforated instrument holder of the type mentioned above, wherein the base portion has: a main limb that can be placed against the top side of the perforated holder support structure; and two opposing side limbs that are laterally adjacent to the main limb, wherein from each of the side limbs of the base portion, at least one flexible tongue, and preferably at least two flexible tongues, are formed on one or both sides, the flexible tongues extending from the side limbs of the base portion in the direction of the perforated holder support structure, and are elastically deflectable relative to the side limbs, such that engagement by at least one flexible tongue... In the manner following the opening of the perforated retainer, the base portion can be positioned such that its main limb rests on the top side of the perforated retainer support structure, and wherein, by applying a compressive force to the base portion only in the direction of the top side of the perforated retainer support structure, the opposing flexible tongue then deflects and automatically inserts into another perforated retainer opening, at which the flexible tongue latches with the edge area that defines the perforated retainer opening, such that the base portion can be secured to the perforated retainer support structure for its intended purpose without the use of tools and in a way that prevents it from falling off.

[0006] Therefore, according to the present invention, the base portion of the retaining device is designed with a flexible tongue extending downward (especially obliquely downward) in the direction of the perforated retainer support structure. By means of this tongue, the base portion can be hooked from the top side of the perforated retainer support structure into one or more perforated retainer openings by means of the flexible tongue on one side of the base portion. Then, by pressing on the base portion in the direction of the top side of the perforated retainer support structure, the flexible tongue provided on the opposite side of the base portion deflects and is drawn into a position where it engages with the rear of the perforated retainer support structure. In this way, it is conceivable that each base portion can be arranged and assembled onto the perforated instrument retainer without the use of tools. After this, the instrument carrier portion can then be releasably arranged on the base portion, for example, by pushing or placing it onto the base portion in the direction of the plane of the perforated retainer support structure, or by attaching it to the base portion in another way through force or form fit. However, it is also conceivable that the base portion, together with the instrument bearing portion already arranged on the base portion, can be releasably secured to the perforated instrument holder in the manner described above.

[0007] For the economic manufacturability and stability of the device, it has been proven that the base portion is a curved sheet metal part, and that the flexible tongue is cut from the curved sheet metal part. In this case, the base portion, including its flexible tongue, can be formed from a flat metal material portion by punching and bending processes. The bending folds between the main limb and the two lateral limbs adjacent to the sides give the base portion high torsional stability, even for the relatively thin wall thickness of the base portion, especially 0.2 to 1.0 mm, especially 0.25 to 0.8 mm, and especially 0.3 to 0.5 mm. In addition, another fold, preferably an inward fold, can be provided at the top free end of the lateral limb, which further increases the torsional stiffness and can also limit the sliding seat socket for the instrument bearing portion.

[0008] Furthermore, it has been shown that flexible tongues are advantageous when used for incisions in the lateral and primary limbs. In such cases, the flexible tongue can be long enough to engage in the perforated retainer opening of the perforated instrument retainer without requiring additional retaining extensions, and the posterior engaging element does not need to be separately provided or attached to the free end of the flexible tongue.

[0009] To reliably secure the device or its base portion to the perforated instrument holder, it has proven advantageous that the free end of each of the flexible tongues is designed or shaped to form a post-engagement area or post-engagement bead. Thus, each flexible tongue can reach a shape-fitted post-engagement position at an edge region with a perforated holder support structure, the edge region defining a corresponding perforated holder opening, and each flexible tongue can also be reliably held there by the resilience of the flexible tongue.

[0010] It has also been proven advantageous that the free end of each of the flexible tongues forms an angle greater than 90°, preferably at least 100°, and preferably at least 110° with the longitudinal extension of the flexible tongue, and thus engages behind the edge region of the opening of the delimited perforated retainer.

[0011] To enable the operator to secure the base portion to the perforated retainer support structure in a simple, reliable, and convenient manner, it has proven advantageous that the free end of each of the flexible tongues preferably forms an arc-shaped ramp corresponding to the flexible tongue. When the base portion is pressed in the direction of the top side of the perforated retainer support structure, the arc-shaped ramp strikes the edge area that defines the opening of the perforated retainer and deflects to latch with the edge area into a rear engagement position.

[0012] As mentioned at the beginning, it has proven convenient for the base portion to form a latching socket or sliding seat socket for the instrument carrying portion, wherein the sliding seat socket is defined laterally by two side limbs of the base portion and at the bottom by a main limb. Furthermore, one or preferably two side limbs may have inwardly projecting portions in their top edge region, particularly by folding the side limbs, thereby defining the sliding seat socket at the top.

[0013] According to one embodiment, the instrument carrier portion, which can be releasably fastened to the base portion, is a polymer plastic part, preferably comprising or composed of silicone resin. While the instrument carrier portion is dimensionally stable, it conveniently has a flexibly deflectable holding area for the instrument. The instrument carrier portion is conveniently individually adapted to the instrument to be stored and includes, for this purpose, retaining structures, particularly retaining arms, and (if necessary) recesses and centering ramps for placing the instrument and, particularly, clamping it within the instrument.

[0014] In principle, perforated instrument holders can have any perforated surface structure, provided that the perforated holder openings are arranged periodically, and thus the arrangement and design can be tailored according to the spacing between the perforated holder openings, particularly maintaining the distance between the tongues. For the production of perforated surface structures primarily for sterilization purposes, it has proven advantageous for perforated instrument holders to have a perforated holder support structure with, in particular, rectangular and preferably square, perforated holder openings defined by connectors narrower than the side length of the rectangle or narrower than the maximum dimension of the perforated holder opening. Specifically, the width of the connectors is no greater than 30% of the maximum dimension of the perforated holder opening, and particularly no greater than 20%, regardless of whether they are rectangular.

[0015] It can also be advantageous that, when viewed from above on the top side, the perforated instrument holder is rectangular, with corresponding longitudinal and transverse directions, and the connector defining the opening of the perforated holder also extends at a 45° angle in either the longitudinal or transverse direction. In such cases, the opening of the perforated holder can also extend at a 45° angle in either the longitudinal or transverse direction of the perforated instrument holder. However, if the base portion is then aligned in either the longitudinal or transverse direction, then to some extent, the rebound force of the flexible tongue causes the relevant flexible tongue to self-center in the corner area of ​​the relevant perforated holder opening.

[0016] Furthermore, it can be proven advantageous for perforated instrument holders to include three-dimensionally constructed, particularly corrugated, perforated holder support structures. In this case, the base portion can be arranged and secured in the high points or peaks of the perforated holder support structure, wherein the base portion does not necessarily rest entirely on these high points or peaks of the perforated holder support structure, but it is conceivable that the perforated holder support structure engages with recesses in the main limbs of the base portion by means of its high points or peaks.

[0017] In the development of this concept, it has been proven advantageous that a recessed portion is formed in the base portion, wherein the perforated retainer support structure can be engaged by means of a protruding portion, thereby further stabilizing the position of the base portion on the perforated retainer support structure.

[0018] In the case of a three-dimensional construction, particularly a corrugated perforated retainer support structure, a flexible tongue engaging with the opening of the perforated retainer or behind its rear engaging end is also arranged on the bottom side, but approximately in the area of ​​the protruding portion of the perforated retainer support structure, and therefore at a certain distance from the support surface of the perforated instrument retainer. This safely prevents strain on the support surface caused by any wear due to 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 metallic material, particularly a sheet of metal, and can be manufactured, in particular, by cutting, punching, and bending processes, especially using laser cutting technology. In this way, the material thickness of the perforated holder support structure can remain constant over its extensions, particularly over the entire bottom area of ​​the perforated basket. However, in principle, a woven perforated holder support structure is also conceivable and sometimes advantageous.

[0020] Regarding the self-centering of the flexible tongue in the corner area of ​​the perforated retainer opening mentioned above, it has been proven advantageous that the distance between two adjacent flexible tongues of the lateral limb corresponds to the distance between two intersection points of the connector defining the perforated retainer opening, or twice or an integer multiple thereof, and thus the flexible tongue can be automatically positioned in the corresponding corner area of ​​the perforated retainer opening.

[0021] Furthermore, protection is claimed for a release device adapted to the base portion, wherein the flexible tongue is an assembly or accessory of the perforated device holder, which can be internally placed through an opening in the base portion against one or more flexible tongues in the area of ​​the lateral limb, and thus these flexible tongues can be deflected from their rear engaged position, allowing the base portion to be released from its position engaged behind the perforated device holder.

[0022] As mentioned at the beginning, 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 the tissue system for a perforated instrument holder according to the invention discussed herein, protection is also claimed for a means for storing, and preferably for holding one or more medical instruments, particularly surgical instruments, in a predetermined arrangement on the perforated instrument holder, said means comprising a base portion and an instrument-carrying portion to which it can be held, said base portion being releasably secured to the perforated instrument holder, said means being characterized in that the base portion has a primary limb that can be placed against a top side, and two opposing lateral limbs adjacent to said primary limb on the sides, and wherein, originating from each of said lateral 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 portion in the direction of the perforated retainer support structure and is elastically deflectable relative to the side limbs, such that the base portion can be positioned such that its main limb is on the top side of the perforated retainer support structure by means of at least one flexible tongue engaging behind the perforated retainer opening, and wherein only by applying a compressive force to the base portion in the direction of the top side of the perforated retainer support structure, the opposing flexible tongue then deflects and automatically inserts into another perforated retainer opening, in which the opposing flexible tongue latches with the edge area defining the perforated retainer opening, such that the base portion can be fastened to the perforated retainer support structure for its intended purpose in a tool-free and anti-dislodgement manner.

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

[0025] Furthermore, protection is claimed for devices having the features described in claim 16 or claim 17, which in turn have the features described in claims 2 to 13.

[0026] Further features, details and advantages of the invention can be found in the appended claims, the drawings and in the following description of preferred embodiments of the invention. Attached Figure Description

[0033] The diagram illustrates an embodiment of a perforated instrument holder 2 for medical, particularly surgical, instruments according to the present invention, used for supplying sterile articles in the medical field. The perforated instrument holder 2 includes a perforated holder support structure 4 having a plurality of perforated holder openings 6, and a device 8 for storing and preferably holding an instrument (not shown) during sterile article circulation. The device 8 includes a base portion 10 and an instrument carrying portion 12 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 example presented here, the perforated retainer support structure 4 is corrugated and therefore has a three-dimensional wave structure. The perforated retainer support structure 4 is formed, for example, by two groups, each group consisting of a plurality of parallel connectors 18, with the connectors 18 of one group extending at right angles to those of the other group, such that they define the perforated retainer opening 6. The perforated retainer support structure 4, composed of the connectors 18, is initially flat and subsequently forms a corrugated structure. Although it is a three-dimensional structure, the perforated retainer opening 6 can be described, for example, in the case of this invention, as substantially square (comparatively...). Figure 4b , 4c That is, when projected vertically onto the base surface of the perforated retainer support structure 4, they have a square shape.

[0035] Figure 2 And other figures illustrating the shape and design of the base portion 10. In the example shown here, the base portion is formed from a flat sheet of metal material, which is shaped by cutting, punching, or bending processes. Figure 2 The shape shown is illustrated. The base portion 10 includes: a main limb 20, which is positioned against the top side 14 of the perforated retainer support structure 4; and two opposing side limbs 22, 24, which laterally abut the main limb, the side limbs being generally defined in a U-shape in the example shown, the U-shape narrowing slightly towards the top when viewed in the direction of arrow 26. Furthermore, the side limbs 22, 24 have inwardly curved edge regions 28 and 30 at their respective top free ends. It can also be seen that, originating from each of the side limbs 22, 24, two flexible tongues 32, 34 are formed on each side. These flexible tongues 32, 34 cut through the material of the previously flat material portion via perforated cuts, thus leaving recessed portions 35 in the main limb 20 and the side limbs 32, 34 of the base portion 10. The flexible tongues bend outwards such that they extend obliquely downwards at an acute angle from the top regions of the lateral limbs 22, 24 in the direction of the perforated retainer support structure 4, and can elastically deflect relative to the lateral limbs 22, 24. Each flexible tongue 34 bends inwards at its free end and forms a post-engagement region 36, to which the associated flexible tongues 32, 34 can engage in the perforated retainer opening 6, and together with the edge region defining the perforated retainer opening 6, form a form-fitting connection with the connector 18 of the perforated retainer support structure 4 to maintain the connection. This reference Figures 3a to 3c To explain: Figure 3a An example of a three-dimensional corrugated perforated retainer support structure 4 and a base portion 10 having its flexible tongues 32, 34 is shown. Figure 3a As can be seen, the base portion 10 is slightly inclined relative to the plane of the perforated retainer support structure 4, making... Figure 3aThe flexible tongue 32 of the left-hand lateral limb 22 engages in the two adjacent perforated retainer openings 6 in the crest area of ​​the perforated retainer support structure 4, and hooks onto the connector 18 by means of each of its subsequent engagement areas 36. From this assembly configuration, only Figure 3b The compressive force in the direction of arrow 38 shown now needs to be applied to the base portion 10 or the other limb 24 in the direction of the perforated retainer support structure 4, so that the opposing flexible tongue 34 strikes the connector 18 having its rear engagement end region 36, and thereby deflects outward, and finally reaches Figure 3c The post-engagement configuration shown depicts a flexible tongue 34 that springs inward after engaging in the openings of the two perforated retainers, thus presenting an anti-detachment assembly position on the perforated retainer support structure 4. In this assembly position, the base portion 10 rests to some extent in the area of ​​the protrusion of the perforated retainer support structure 4, and is again arranged parallel to the plane of the perforated retainer support structure 4. However, in the example embodiment shown, the base portion is not resting exactly on top of the high point of the protrusion of the perforated retainer support structure 4, but rather at a relatively high position on the connector thereto. The high point or apex of the protrusion inserts into a recess 35 in the base portion, which is created here by the cut flexible tongue 32. If the base portion is long and extends over multiple protrusions of the perforated retainer support structure, multiple such recesses may be formed in the base portion to allow the high point or apex of the protrusion to insert or engage in this manner.

[0036] In an embodiment not shown, if the flexible tongue is not suitable for two perforated retainer openings arranged one after another in a perforated basket, but is instead designed to engage in perforated retainer openings that are further separated from each other, the base portion may have one or more additional recesses into which the high point or apex of the intermediate protrusion of the three-dimensionally constructed perforated body structure can be inserted. This insertion reduces the mounting height of the base portion above the perforated retainer support structure and causes its position to be displaced relative to the lateral direction (i.e., in...). Figure 5 The direction of the arrow in the diagram is stable because the flexible tongue also has a certain degree of elasticity in the lateral direction, which is not necessary in this direction itself.

[0037] Ideally, the surfaces of the apex of the protrusion in the corrugated perforated retainer support structure and the surfaces of the main limbs of the base portion lie in a single plane; this allows for a maximum reduction in the mounting height of the base portion while still allowing the instrument carrier portion to be inserted without impacting the apex of the protrusion. For the stability and assembly safety of the instrument carrier portion, it is particularly advantageous for its bottom side to rest on or be adjacent to the top side of the main limbs of the base portion.

[0038] Figures 4a to 4cThis is a further view of the base portion 10 assembled on the perforated retainer support structure 4.

[0039] exist Figure 4c In the middle, arrow 40 indicates the insertion point, such as... Figure 3a and 3b After entering the perforated retainer opening of the three-dimensional corrugated perforated retainer support structure 4 shown, the flexible tongues 32, 34, due to their resilience, are guided along the connector 18 in a self-centering manner to the stable assembly position shown. The free ends of the flexible tongues 32, 34 are preferably rounded or chamfered, as this reduces the necessary deflection of the flexible tongues 32, 34 when sliding on the connector of the corrugated perforated retainer support structure extending obliquely thereto. This makes it possible to work with stiffer or stronger spring legs and reduces the risk of injury to the user's gloves or hands during assembly without significantly affecting the stability of the base portion anchored to the perforated retainer support structure.

[0040] Figure 5 The completed retaining device 8 is shown, allowing the instrument-bearing portion 12 of the retaining device to be pushed onto the base portion 10 in the direction of arrow 42, parallel to the plane of the perforated retainer support structure 4. The base portion 10 forms a dovetail-shaped sliding seat socket for complementing the instrument-bearing portion 12 by means of its inwardly curved edge regions 28, 30 at its top. However, it should be explicitly mentioned that the instrument-bearing portion 12 and the base portion 10 can also be assembled together in another manner and releasably fastened to each other. Specifically, it is also conceivable that the base portion 10 can be secured to the pre-assembled instrument-bearing portion 12 against the perforated retainer support structure 4 in the manner described.

[0041] However, in order to release the retaining device 8 or the base portion 10 from the perforated retainer support structure 4, in the example shown, it is convenient to release the instrument carrying portion 12 from the still assembled base portion 10, so that it can be released by means of... Figure 6a and 6b The release device 44 shown is used to approach the flexible tongues 32, 34 so that the flexible tongues 32, 34 are in Figure 6bThe base portion 10 is deflected outward in the direction of arrow 46, releasing it from its engagement with the connector 18 of the perforated retainer support structure 4. The base portion 10 can then initially pivot upward away from the perforated retainer support structure 4 and subsequently move to the opposite side of arrow 46, releasing the flexible tongue 34 on the opposite lateral limb 24 from its subsequent engagement, and ultimately allowing complete removal of the base portion 10. Alternatively, for the corresponding design of the length and pretension of the flexible tongues 32, 34, it is, however, in principle conceivable to move the base portion 10 to the left in the direction of arrow 46 without the use of tools, with or without the instrument bearing portion 12, such that... Figure 6b The flexible tongues 32 shown on the left are released from their positions where they engage behind the connector 18, and the base portion can then pivot upward and be removed from the perforated retainer support structure 4 to the opposite side without the use of tools.
