Description

Technical Field

[0001] This disclosure relates to the fastening of support elements or retainers for medical devices used, particularly for minimally invasive surgical procedures in sterile sieve baskets. Background Technology

[0002] In minimally invasive surgery, medical instruments are available and stored again in sterile sieve baskets. These sterile sieve baskets containing instruments are inserted into closable sterile containers and, if necessary, stacked within them.

[0003] Existing technology

[0004] The applicant's name is known from the prior art. The sterilization sieve basket has a bottom shaft that appears as a trapezoidal step when viewed in cross-section, thus eliminating the need for supports on the sieve basket. The bottom shaft has a perforated grid, wherein the connecting pieces are positioned at a 45-degree angle to either the edge of the bottom shaft or relative to the edge of the sterilization sieve basket.

[0005] Furthermore, it is known from the prior art that the instrument retainer is fastened to the upper side of the bottom of the sterilization sieve basket by means of a fastening clip. For increased flexibility, the fastening clips can also be staggered. Such a fastening clip, named JG301R, is disclosed on the Internet at https: / / endoskopie.bbraun.com / p / PRID00006221. Two arm rows, oriented opposite each other about a central axis, are arranged on the main section of the fastening clip. Each arm row has a first retaining arm and a second retaining arm, on which lateral locking lugs are formed respectively, wherein the locking lugs of the two retaining arms in each arm row point towards each other. The retaining arms of the fastening clip are inserted from below through a perforated grid at the bottom of the sterilization sieve basket. The fastening clip is clamped onto the perforated grid by means of the locking lugs. The silicone tab of the instrument retainer can then be pushed between the retaining arms.

[0006] However, as shown on this fastening clip, it cannot be installed horizontally at the bottom of the shaft of a footless sterilization sieve basket (e.g., in the above-mentioned...). The clamps extend downwards from the bottom of the shaft, making the sterilization basket unstable (e.g., in a sterilization container) depending on their distribution at the bottom of the shaft. Furthermore, the downward-extending clamps may scratch or even damage objects located below them (e.g., the bottom of the sterilization container). Summary of the Invention

[0007] The objective of this disclosure is to provide a fastening clamp for the bottom of a sterilization sieve basket and an assembly having a sterilization sieve basket and at least one such fastening clamp, wherein the associated sterilization sieve basket is stable in all configurations or positions of the fastening clamp. Furthermore, objects located below (e.g., the bottom of a sterilization container) should not be scratched or damaged by the fastening clamp.

[0008] This task is solved according to the invention in terms of fastening clamps and components.

[0009] The fastening clip according to this disclosure is configured and designed to be tool-free fastened to the bottom of a perforated shaft of a preferably footless sterilization sieve basket. The fastening clip has a main section on which two rows of arms are arranged opposite each other about a central axis. Each row of arms has a first retaining arm and a second retaining arm, on which lateral locking lugs are formed respectively. The locking lugs of the two retaining arms of each row of arms point opposite each other and are used to clamp the fastening clip onto the perforated grid at the bottom of the shaft. A first edge between the two first retaining arms and a second edge between the two second retaining arms extend transversely to the central axis on the main section of the fastening clip. According to the invention, a gap or opening is formed on each of the two edges. Therefore, it is possible that the main section of the installed fastening clip does not extend downwards from the bottom of the shaft, but is completely embedded in the bottom of the shaft from below, because the lower tab cross of the bottom of the shaft is embedded from above into the gap of the main section. Thus, the main section will not scratch or damage the object below (e.g., the bottom of a sterilization container).

[0010] Preferably, the two edges of the main section extend laterally to the central axis.

[0011] In a smaller version of the fastening clamp, the two gaps or openings extend transversely to the central axis, preferably at least one-third or more of the corresponding width of the main section or the corresponding distance of the (opposite) retaining arms. This allows the tab cross to be largely embedded in the corresponding gaps and the fastening clamp to be installed particularly high and / or the main section to have an advantageous thickness, without the main section protruding downwards from the bottom of the shaft.

[0012] In a smaller version of the fastening clip, the two gaps or openings preferably extend along the central axis for at least one-eighth of the length of the main section. This allows the tab cross to be largely embedded in the corresponding gaps and the fastening clip to be installed particularly high and / or the main section to have an advantageous thickness without protruding downwards from the bottom of the shaft.

[0013] In a larger version of the fastening clamp, intermediate arms are provided between the two retaining arms of the arm row. Additionally, a further gap, constructed as a through gap, is provided approximately centrally in the main section. Thus, a total of three tab crosses can be embedded into the corresponding gaps. In the larger version of the fastening clamp, it is also preferable to form a retaining section for the silicone tabs on the free end section of the intermediate arm.

[0014] Preferably, retaining sections for silicone tabs used for instrument retainers are formed on the free end sections of the retaining arms and / or intermediate arms. Preferably, the retaining sections are arranged in pairs facing each other, and more preferably facing each other in pairs. That is, the retaining sections of the two first retaining arms preferably point towards each other, and / or the retaining sections of the two second retaining arms point towards each other, and / or the retaining sections of the intermediate arm point towards each other. In a design that is simple in manufacturing technology, the fastening clip is a bent sheet metal component. In an improved design that is simple in manufacturing and installation technology, the central axis is also an axis of symmetry.

[0015] In a first variation of the larger version of the fastening clamp, additional locking lugs are provided on each of the two intermediate arms, extending in the opposite direction to the locking lug of the first retaining arm. Preferably, additional locking lugs are also provided on each of the two intermediate arms, extending in the opposite direction to the locking lug of the second retaining arm. Therefore, each arm row can retain two tab crosses on both sides, improving the retention of the fastening clamp.

[0016] In the second variant of the larger version, the intermediate arm is a tab without locking lugs. Therefore, straight edge segments are formed on this tab relative to the locking lugs of the two adjacent retaining arms. Thus, each arm row also securely clamps two tab crosses, but only on one side of the locking lug of each retaining arm. The two edge segments of each tab can be parallel to each other.

[0017] The installation of the fastening clip is simplified when lead-in ramps are also formed on the intermediate arms above the locking lugs on the four retaining arms, and in the case of the first variant of the larger version of the fastening clip. The opposing lead-in ramps can form a funnel-shaped free space into which the tab is introduced in a cross shape.

[0018] The component according to this disclosure has a sterilization sieve basket, which can be constructed and designed to be inserted into a sterilization container, preferably without legs. The bottom of the axial section of the sterilization sieve basket has a perforated grid, wherein four tabs of each perforated grid form a tab cross. The tab cross is arranged at two different heights at the bottom of the axial section. At least one of the aforementioned fastening clips can be tool-free to clamp or hold onto the bottom of the axial section. Here, the main section of the installed fastening clip can be completely embedded in the bottom of the axial section from below, because the lower tab cross of the bottom of the axial section is embedded in the opening of the main section from above. The main section then does not extend downwards from the bottom of the axial section, but is embedded in it. Therefore, the main section will not scratch or damage the object located below (e.g., the bottom of the sterilization container).

[0019] Preferably, the splice crosses are arranged in rows of splice crosses, which are alternately arranged at two different heights, wherein the splice crosses extend along the entire bottom of the shaft and are parallel to the bottom of the shaft or the edge of the sterilization sieve basket.

[0020] Between the two retaining arms of each arm row of at least one fastening clamp, one or two tab crosses from each tab cross row can be accommodated or received. One or both tab crosses abut against the locking lugs and are thus held in place. In the case of two tab crosses per arm row, the middle arm of the larger version of the fastening clamp extends between the two tab crosses.

[0021] In a smaller version of the fastening clamp, the two adjacent cross segments of the lower cross segment can be embedded into the gaps or openings formed on the edge of the main section.

[0022] In larger versions of the fastening clamp, the three adjacent crosses of the lower cross-shaped inserts are embedded in the gaps of the main section. More precisely, two crosses are embedded in two gaps or openings formed at the edges, while one cross is embedded in the central gap that is formed as a through gap.

[0023] In a particularly preferred improvement of the disclosed assembly, the tab at the bottom of the shaft is angled at 45 degrees relative to the bottom of the shaft or the edge of the sterilization sieve basket. Since the tabs are arranged in a cross shape between the retaining arms of the arm row, although the tabs are angled at 45 degrees above the bottom of the shaft, at least one fastening clip (with its corresponding central axis) is secured parallel to or at 90 degrees relative to the bottom of the shaft or the edge of the sterilization sieve basket. Therefore, the silicone tabs of the instrument retainer are also pushed in parallel to or at 90 degrees to the bottom of the shaft or the edge of the sterilization sieve basket.

[0024] When the tabs at the bottom of the shaft are angled at 45 degrees relative to the edge of the bottom of the shaft, the two tab crosses can be embedded particularly deeply into the two gaps or openings near the edges. And when the two gaps or openings near the edges are mirror-symmetrical with respect to the central axis and each has three edges that are approximately perpendicular to each other, there is a minimal weakening of the main section. Thus, two of the four tabs of the relevant tab cross can be arranged in the two corners of the corresponding gaps or openings near the edges. Here, these two gaps or openings can also be used as positioning aids.

[0025] In a similar manner in principle, in larger versions, if the through-hole is rectangular and if the four tabs of the associated tab cross are arranged at the four corners of the through-hole, then the central tab cross can be embedded particularly deeply into another gap constructed as a through-hole and / or into the smallest possible weakened portion of the main segment. In this design, the through-hole can also serve as a positioning aid.

[0026] The silicone tabs of the instrument retainer are preferably held below the retaining sections, which are formed on the free end sections of the four retaining arms and, if necessary, on the free end sections of the two intermediate arms.

[0027] Unlike the main section which is advantageously embedded in the bottom of the shaft from below, alternatively, a lower mounting position where the at least one fastening clamp is placed on the bottom of the shaft is also possible. Here, a tab cross with a smaller height is accommodated between the retaining arms of the two arm rows. This lower mounting position is also mechanically defined and provides reliable retention of the fastening clamp on the bottom of the shaft. In the lower mounting position, the main section of the fastening clamp is also flat. However, this main section extends downward from the bottom of the shaft and, to some extent, functions as a support. Attached Figure Description

Detailed Implementation

[0037] Three embodiments of this disclosure are described below with reference to the accompanying drawings.

[0038] Figure 1 An assembly according to a first embodiment of the present disclosure is shown. The assembly has a sterilization basket 1, from which only one edge 2 and a cut-off portion of its shaft bottom 3 are shown. The shaft bottom 3 has a perforated grid formed by tabs 4 arranged perpendicularly to each other (in a top view). The tabs 4 are preferably angled at 45° relative to the edge 2. Four tabs 4 form a tab cross 6.

[0039] The cross-shaped plates 8a and 8b extend parallel to the edge 2 of the sterilization sieve basket 1 at two different heights, wherein the lower cross-shaped plate 8a and the upper cross-shaped plate 8b are always alternately arranged. Therefore, as long as the corresponding axial shape is obtained, the angle can of course be deviated upward or downward.

[0040] according to Figure 1A larger version of the fastening clip 10 is inserted and clamped through the rectangular openings of the perforated grid (viewed in top view). More precisely, the first and second arm rows extend parallel to the tab cross rows 8a, 8b and parallel to the edge 2, wherein each arm row has a first retaining arm 12, an intermediate arm 14 configured as a tab, and a second retaining arm 16. The two intermediate arms 14 are configured so narrow that they extend through the corresponding openings of the perforated grid without directly contacting the tab 4 or the tab cross 6. The four retaining arms 12, 16 each have locking lugs 18 that abut against the upper side of the tab cross 6. Thus, the fastening clip 10 is clamped onto the shaft bottom 3 of the sterilization sieve basket 1.

[0041] On the four retaining arms 12, 16, a corresponding guide ramp 21 is formed above the corresponding locking lug 18. Thus, a guide aid is formed for each of the four associated tab crosses 6.

[0042] Figure 2 It has the observation direction along the cross arrangement 8a and 8b of the splicing plate. Figure 1 Further illustration of the first embodiment of the components. Retaining sections 19 are formed on the upper end sections of the retaining arms 12, 16 and the intermediate arm 14. These retaining sections surround the silicone tabs of the instrument retainer (not shown), which are therefore also arranged parallel to the tab cross rows 8a, 8b.

[0043] according to Figure 2 The fastening clip 10 is clamped onto the two lower tab cross rows 8a, so that the planar main section 22 of the fastening clip 10 is arranged below the shaft bottom 3. These so-called lower mounting positions of the fastening clip 10 are also possible.

[0044] Conversely, if the upper mounting position is selected, the main section 22 can be arranged above the lower tab cross row 8a and thus completely embedded in the shaft bottom 3. Figure 4 and Figure 7 The fastening clips 110 and 210 are shown in the upper mounting position, respectively.

[0045] Figure 3 This is a diagram of the fastening clip 110 according to the second embodiment of the present disclosure.

[0046] First, the explanation Figure 1The fastening clips 10 and 110 are respectively characterized as sheet metal bending components. Two arm rows extend along a central axis 20, which serves as the axis of symmetry. These two arm rows each have a first retaining arm 12, an intermediate arm 14, 114, and a second retaining arm 16. A main section 22 is arranged between these two arm rows. Three gaps 24a and 24b are provided in the main section 22, into which one of the tabs 6 of each of the lower tab cross rows 8a can be embedded from above. More precisely, two external gaps 24a and another gap 24b formed as a central through gap are provided. The two external gaps 24a are U-shaped and arranged on the edges of the main section 22.

[0047] and Figure 1 The fastening cavity 10 in the middle is different from the first embodiment, according to Figures 3 to 5 The second fastening clamp 110 not only has locking lugs 18 on the retaining arms 12, 16, but also has additional locking lugs 18 on both sides of each intermediate arm 114. Each locking lug 18 of the intermediate arm 114 extends in the opposite direction to the locking lugs 18 of the retaining arms 12, 16.

[0048] Figure 4 It has Figure 1 The bottom of the shaft 3 and Figure 3 A side view of the components of the second embodiment of the fastening clip 110 is shown, clearly illustrating the four locking lugs 18 of the arm row. Thus, each arm row with two tab crosses 6 can abut and hold the tab crosses 6 on both sides.

[0049] On the four retaining arms 12, 16 and on the two intermediate arms 114, corresponding guide ramps 21 are formed above the locking lugs 18. This forms a V-shaped guide funnel for each of the four associated tab crosses 6.

[0050] Figure 5 yes Figure 4 Another embodiment of the components is shown in the lower diagram. The main section 22 is shown in full here, wherein the tab crosses 6 in the lower tab cross row 8a are respectively accommodated in three gaps 24a, 24b. This achieves the upper mounting position, where the main section 22 does not affect the storage position of the sterilization sieve basket 1, even when the sterilization sieve basket has no legs.

[0051] Figure 6 This is a diagram of the fastening clip 210 according to a third embodiment of the present disclosure. This is a so-called smaller version, which is smaller along the central axis 20 than in... Figures 1 to 5 The two larger versions shown are shorter. In the third embodiment, the two intermediate arms 14 are omitted.

[0052] Figure 7 It has Figure 6A side view of the components of the third embodiment of the fastening clip 210. It can be seen that the two retaining arms 12, 16 of each arm row directly accommodate only one tab cross 6 between them.

[0053] Figure 8 yes Figure 7 Another illustration of the third embodiment of the components is shown below. In the third embodiment, the additional gap 24b on the main section 22 is omitted because only the two tab crosses 6 in the lower tab cross row 8a must be embedded in the corresponding gap 24a.

[0054] Figure 4 , 5 Figures 7 and 8 show the fastening clamp 110; 210 is located in a preferred higher mounting position on the shaft bottom 3 of the sterilization sieve basket 1, wherein the two arm rows are effectively connected to the upper tab cross row 8b, while the gaps 24a, 24b accommodate the tab cross 6 in the lower tab cross row 8a.

[0055] In summary, the above embodiments thus demonstrate a fastening clip designed for tool-free fastening to the perforated or grid-like shaft bottom 3 of the sterilization sieve basket. For this purpose, the fastening clip has at least the following features:

[0056] - A preferred plate-shaped or tongue-shaped main section or substrate 22, on which two arm rows are arranged or formed opposite each other relative to the central axis or longitudinal axis 20 of the tongue-shaped (generally rectangular in top view) main section. That is, a plurality of preferred plate-shaped arms are formed or arranged on each longitudinal side of the tongue-shaped main section, and these arms are correspondingly spaced apart from each other in the longitudinal direction of the main section.

[0057] - Each arm row has at least one first retaining arm 12 and a second retaining arm 16, the first retaining arm and the second retaining arm being generally perpendicular to the plate-shaped / tongue-shaped main section 22 or extending at an angle of 90°.

[0058] - On the opposing side edges of at least two arms in each longitudinal side / arm row, locking lugs or locking protrusions 18 are formed respectively, which are opposite to each other and point towards each other.

[0059] A first edge extends over the main section 22 between the two first retaining arms 12, and a second edge extends between the two second retaining arms 16, wherein a gap or recess 24a is formed on each of the two edges. In other words, rectangular gaps or notches 24a are preferably formed on the longitudinally spaced end edges of the (plate-shaped / tongue-shaped) main section, the gaps or notches extending in the longitudinal direction. Preferably, the corners of the rectangular gaps are rounded.

[0060] This means that the fastening clamp has at least four clamping arms 12, 16, each having opposing locking lugs 18, which are formed or arranged on a common substrate (main section) 22 and extend at an angle of 90° (positive / negative 20°), wherein at least two clamping arms are always arranged longitudinally apart on every two opposing longitudinal sides of the substrate 22. At least one preferably rectangular gap 24a, 24b is formed in the substrate 22. This gap can be configured as a closed, perforated gap 24b in the central region of the substrate 22 and / or a partially open notch 24a on at least one end edge (lateral side) connecting two longitudinal sides or on both end edges (lateral sides) of the substrate 22.
