Description

Technical Field

[0001] The present disclosure relates to the fastening of support elements or holders for medical instruments, particularly for minimally invasive surgery, in sterile screen baskets. Background Art

[0002] In minimally invasive surgery, medical instruments are available and stored again in sterile sieve baskets. Such sterile sieve baskets with instruments are inserted into closable sterile containers and, if necessary, are also stacked therein.

[0003] Prior art

[0004] It is known from the prior art that the applicant's name The sterile sieve basket has a shaft bottom which is stepped in a trapezoidal shape when viewed in cross section, so that the feet on the sterile sieve basket can be omitted. The shaft bottom has a perforated grid, wherein the webs are inclined at 45 degrees to the edge of the shaft bottom or to the edge of the sterile sieve basket.

[0005] Furthermore, it is known from the prior art that the instrument holder is fastened to the upper side of the bottom of the sterilization screen basket by means of a fastening clamp. In order to increase flexibility, the fastening clamp can also be staggered. Such a fastening clamp of the applicant with the name JG301R is disclosed on the Internet at the address https: / / endoskopie.bbraun.com / p / PRID00006221. Two arm rows are arranged on the main section of the fastening clamp, which are opposite to each other with respect to the central axis, wherein each arm row has a first holding arm and a second holding arm, on which lateral latching lugs are respectively formed, wherein the latching lugs of the two holding arms of each arm row point to each other. The holding arms of the fastening clamp are inserted from below through the perforated grid at the bottom of the sterilization screen basket. The fastening clamp is clamped on the perforated grid by means of the latching lugs. Afterwards, the silicone tabs of the instrument holder can be pushed between the holding arms.

[0006] However, it has been shown that such a fastening clamp cannot be mounted horizontally at the bottom of the shaft of a sterile sieve basket without feet (e.g., in the above-mentioned The sieve basket is located at the bottom of the shaft, and the fastening clip extends far downward from the bottom of the shaft, so that the sterilization sieve basket cannot be stabilized (for example in a sterilization container) depending on the distribution of the fastening clip at the bottom of the shaft. In addition, the fastening clip extending downward may scratch or even damage the object located below it (for example, the bottom of the sterilization container). Summary of the invention

[0007] The object of the present disclosure is to provide a fastening clamp for the shaft bottom of a sterile sieve basket and an assembly with a sterile sieve basket and at least one such fastening clamp, wherein the associated sterile sieve basket is stable in all configurations or positions of the fastening clamp. Furthermore, objects located underneath, such as the bottom of a sterile container, should not be scratched or damaged by the fastening clamp.

[0008] This object is achieved with respect to the fastening clip by means of the combination of features of claim 1 and with respect to the assembly by means of the combination of features of claim 11 .

[0009] The fastening clamp according to the present disclosure is arranged and designed to be fastened to the perforated shaft bottom of the sterilization screen basket preferably without support feet without tools. The fastening clamp has a main section, on which two arm rows are arranged opposite to each other with respect to the central axis, wherein each arm row has a first holding arm and a second holding arm, on which lateral locking lugs are respectively formed. The locking lugs of the two holding arms of each arm row point relative to each other and are used to clamp the fastening clamp on the perforated grid of the shaft bottom. On the main section of the fastening clamp, a first edge between the two first holding arms and a second edge between the two second holding arms extend transversely to the central axis. According to the present invention, a recess or gap is formed on each of the two edges. It is therefore possible that the main section of the installed fastening clamp does not extend downward from the shaft bottom, but is completely embedded in the shaft bottom from below, because the lower tab cross of the shaft bottom is embedded in the recess of the main section from above. Therefore, the main section will not scratch or damage the object located below (for example, the bottom of the sterilization container).

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

[0011] In a smaller version of the clamping clip, the two cutouts or recesses extend transversely to the center axis preferably over at least one third of the respective width of the main section or the respective distance of the (opposite) retaining arms. The web cross can thus be embedded to a greater extent in the respective recesses and the clamping clip can be mounted particularly high and / or the main section can have an advantageous thickness without the main section protruding downwards from the shaft base.

[0012] In a smaller version of the clamping clip, the two cutouts or recesses preferably extend along the central axis over at least one eighth of the length of the main section. The web cross can thus be embedded to a greater extent in the respective recess and the clamping clip can be mounted particularly high and / or the main section can have an advantageous thickness without the main section protruding downwards from the shaft base.

[0013] In a larger version of the fastening clip, an intermediate arm is provided between two retaining arms of the arm row. In addition, a further recess is provided approximately centrally in the main section, which is designed as a through-cut recess. Thus, a total of three web crosses can be embedded in the respective recess. In a larger version of the fastening clip, a retaining section for the silicone web is preferably also formed on the free end section of the intermediate arm.

[0014] Preferably, a holding section for the silicone web of the instrument holder is formed on the free end section of the holding arm and / or the intermediate arm. Preferably, the holding sections are arranged opposite each other in pairs, preferably facing each other in pairs. That is to say, the holding sections of the two first holding arms preferably point towards each other, and / or the holding sections of the two second holding arms point towards each other, and / or the holding sections of the intermediate arms point towards each other. In a design that is simple in terms of manufacturing technology, the fastening clamp is a bent sheet metal part. In an improved design that is simple in terms of manufacturing technology and installation technology, the center axis is also the axis of symmetry.

[0015] In a first variant of a larger version of the fastening clip, an additional latching lug is provided on each of the two middle arms, which latching lug extends opposite to the latching lug of the first holding arm. Preferably, an additional latching lug is also provided on each of the two middle arms, which latching lug extends opposite to the latching lug of the second holding arm. Thus, each arm row can hold two tab crosses on both sides, and the holding of the fastening clip is improved.

[0016] In a second, larger version, the middle arm is a tab without a latching lug. For this purpose, in particular a straight edge section is formed on the tab in each case relative to the latching lugs of two adjacent retaining arms. Thus, each arm row also clamps two tab crosses, but only on one side of the latching lugs of the retaining arms. The two edge sections of each tab can be parallel to one another.

[0017] The installation of the clamping clip is simplified when an insertion ramp is formed above the latching lugs on the four retaining arms and also on the middle arm in the case of a first variant of the larger version of the clamping clip. The mutually opposite insertion ramps can form a funnel-shaped free space into which the web is introduced in a cross shape.

[0018] The assembly according to the present disclosure has a sterilization sieve basket, which can be constructed and designed to be inserted into a sterilization container, preferably without feet. The shaft bottom of the sterilization sieve basket has a perforated grid, wherein each of the four tabs of the perforated grid forms a tab cross. The tab cross is arranged at two different heights of the shaft bottom. At least one of the above-mentioned fastening clips can be clamped or clamped on the shaft bottom without tools. Here, the main section of the installed fastening clip can be completely embedded in the shaft bottom from below, because the lower tab cross of the shaft bottom is embedded in the recess of the main section from above. The main section then does not extend downward from the shaft bottom, but is embedded in the shaft bottom. Therefore, the main section will not scratch or damage the object located below (for example, the bottom of the sterilization container).

[0019] Preferably, the rib crosses are arranged in rib cross rows which are arranged alternately at two different heights, wherein the rib cross rows extend along the entire shaft base and are parallel to the shaft base or to the edge of the sterile screen basket.

[0020] Between the two retaining arms of each arm row of at least one fastening clip, one or two web crosses of a web cross row can be accommodated or held. One web cross or two web crosses rest against the latching lug and are thus held. In the case of two web crosses per arm row, a middle arm of a larger version of the fastening clip extends between the two web crosses.

[0021] In a smaller version of the clamping clip, two mutually adjacent web crosses of the lower web cross row can each be embedded in a recess or cutout formed at the edge of the main section.

[0022] In the larger version of the clamping clip, three mutually adjacent crosses of the lower cross row of crosses are respectively embedded in the recesses of the main section. More precisely, two crosses are embedded in two recesses or cutouts formed on the edges, and one cross is embedded in the central recess formed as a through-gap.

[0023] In a particularly preferred development of the disclosed assembly, the tabs of the shaft base are arranged at an angle of 45 degrees to the edge of the shaft base or the sterile sieve basket. Due to the cross-arrangement of the tabs between the holding arms of the arm row, despite the tabs being arranged at an angle of 45 degrees on the upper side of the shaft base, at least one fastening clip (the corresponding center axis of which) is fastened parallel to or at 90 degrees to the edge of the shaft base or the sterile sieve basket. The silicone tabs of the instrument holder are therefore also pushed in parallel to or at 90 degrees to the edge of the shaft base or the sterile sieve basket between the holding arms.

[0024] When the webs of the shaft base are inclined at 45 degrees to the edge of the shaft base, the two web crosses can be embedded particularly deeply in the two edge-adjacent recesses or gaps, and when the two edge-adjacent recesses or gaps are mirror-symmetrical to the central axis and each have three edges that are inclined approximately at right angles to each other, there is the smallest possible weakening of the main section. Two of the four webs of the relevant web cross can then be arranged in the two corners of the corresponding edge-adjacent recesses or gaps. In this case, the two recesses or gaps can also serve as positioning aids.

[0025] In a similar manner in principle, in a larger version, if the through-hole is rectangular and if the four webs of the relevant web cross are arranged in the four corners of the through-hole, the central web cross can be embedded particularly deeply in the further hole designed as a through-hole and / or in the smallest possible weakening of the main section. In this embodiment, the through-hole can also be used as a positioning aid.

[0026] The silicone webs of the instrument holder are preferably held below holding sections which are formed on the free end sections of the four holding arms and, if appropriate, also on the free end sections of the two central arms.

[0027] In contrast to the advantageous embedding of the main section into the shaft base from below, a lower mounting position of the at least one fastening clip on the shaft base is also possible as an alternative. Here, a web 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 a secure hold of the fastening clip on the shaft base. In the lower mounting position, the main section of the fastening clip is also flat. However, it protrudes downward from the shaft base here and acts as a foot to a certain extent.

[0035] Figure 8 yes Figure 7 A further illustration from below of a third exemplary embodiment of an assembly in FIG. DETAILED DESCRIPTION

[0036] Three embodiments of the present disclosure are described below based on the drawings.

[0037] Figure 1 An assembly according to a first exemplary embodiment of the disclosure is shown. The assembly has a sterile sieve basket 1, of which only one of the edges 2 and a section of the shaft base 3 are shown. The shaft base 3 has a perforated grid formed by webs 4 arranged perpendicularly to one another (in a top view). The webs 4 are preferably inclined at 45° to the edge 2. Four webs 4 each form a web cross 6.

[0038] The cross-rows 8a, 8b extend at two different heights parallel to the edge 2 of the sterilizing screen basket 1, wherein lower cross-rows 8a and upper cross-rows 8b are always alternately provided. Therefore, as long as the corresponding shaft shape is obtained, it is of course also possible to deviate from the angle upward or downward.

[0039] according to Figure 1 , a larger version of the disclosed fastening clip 10 is inserted and clamped through the rectangular opening of the perforated grid (viewed in top view). More precisely, the first and second arm rows extend parallel to the web cross rows 8a, 8b and parallel to the edge 2, wherein each arm row has a first holding arm 12, an intermediate arm 14 designed as a web, and a second holding arm 16. The two intermediate arms 14 are designed so narrow that they extend through the corresponding opening of the perforated grid without directly contacting the web 4 or the web cross 6. The four holding arms 12, 16 each have a latching lug 18, which each rests on the upper side of the web cross 6. The fastening clip 10 is thus clamped on the shaft base 3 of the sterile screen basket 1.

[0040] On the four holding arms 12, 16, corresponding insertion bevels 21 are formed above the corresponding latching lugs 18. Thus, an introduction aid is formed for each of the four associated web crosses 6.

[0041] Figure 2 is a direction of observation along the cross rows of tabs 8a, 8b Figure 11. Holding sections 19 are formed on the upper end sections of the holding arms 12, 16 and the middle arm 14, which surround the silicone webs of the instrument holder (not shown) and are therefore also arranged parallel to the web cross rows 8a, 8b.

[0042] according to Figure 2 , the clamping clip 10 is clipped onto the two lower web cross rows 8a, so that the flat main section 22 of the clamping clip 10 is arranged below the shaft base 3. These so-called lower installation positions of the clamping clip 10 are also possible.

[0043] If, on the other hand, the upper installation position is selected, the main section 22 can be arranged above the lower web cross 8 a and thus be completely embedded in the shaft base 3 . Figure 4 and Figure 7 The fastening clips 110 , 210 are each shown in an upper installation position.

[0044] Figure 3 is a diagram of a fastening clip 110 according to a second embodiment of the present disclosure.

[0045] First, we will explain Figure 1 The corresponding features of the fastening clip 10 in the embodiment are as follows: the fastening clip 10, 110 is a sheet metal bent part. Two arm rows extend along the central axis 20 as the axis of symmetry, and the two arm rows respectively have a first retaining arm 12, an intermediate arm 14, 114 and a second retaining arm 16. The main section 22 is arranged between the two arm rows. Three gaps 24a, 24b are provided in the main section 22, and each of the web crosses 6 of the lower web cross row 8a can be buried in the gap 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 are arranged on the edge of the main section 22.

[0046] and Figure 1 The first embodiment of the fastening cavity 10 is different from that of the first embodiment of the fastening cavity 10. Figures 3 to 5 The second fastening clip 110 has not only latching lugs 18 on the holding arms 12, 16, but also further latching lugs 18 on both sides on each intermediate arm 114. Each latching lug 18 of the intermediate arm 114 extends opposite to the latching lugs 18 of the holding arms 12, 16.

[0047] Figure 4 Is has Figure 1 The bottom 3 and Figure 3 110 in the side view of the assembly of the second embodiment of the fastening clip 110, wherein the four latching lugs 18 of the arm row are clearly presented. Therefore, each arm row with two tab crosses 6 can abut against and hold the tab cross 6 on both sides.

[0048] On the four holding arms 12, 16 and on the two central arms 114, corresponding insertion bevels 21 are formed above the latching lugs 18. Thus, a V-shaped insertion funnel is formed for each of the four associated web crosses 6.

[0049] Figure 5 yes Figure 4 24a, 24b. A further illustration from below of a second exemplary embodiment of an assembly in FIG. Here, main section 22 is shown in its entirety, wherein web crosses 6 in lower web cross row 8a are each accommodated in three recesses 24a, 24b. An upper mounting position is thus achieved, wherein main section 22 does not influence the storage position of sterile sieve basket 1, even when the latter is without feet.

[0050] Figure 6 is a diagram of a 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 in are shorter. In a third embodiment, the two intermediate arms 14 are omitted.

[0051] Figure 7 Is has Figure 6 2 is a side view of an assembly of a third embodiment of a fastening clip 210 in FIG. It can be seen that the two retaining arms 12 , 16 of each arm row accommodate only one web cross 6 directly between them.

[0052] Figure 8 yes Figure 7 . In the third embodiment, the additional recess 24b on the main section 22 is omitted, because only the two web crosses 6 in the lower web cross row 8a must be embedded in the corresponding recess 24a.

[0053] Figure 4 , 5 , 7 and 8 show the fastening clip 110; 210 in a preferred higher installation position on the axial bottom 3 of the sterilizing screen basket 1, wherein the two arm rows are respectively operatively connected to the upper web cross row 8b, and the gaps 24a, 24b accommodate the web cross 6 in the lower web cross row 8a.

[0054] In summary, the above-described embodiments therefore show a fastening clamp which is designed for tool-free fastening on a perforated or grid-like shaft base 3 of a sterile sieve basket. To this end, the fastening clamp has at least the following features:

[0055] A preferably plate-shaped or tongue-shaped main section or base plate 22, on which two rows of arms are arranged or formed, which are located opposite each other with respect to the center axis or longitudinal axis 20 of the tongue-shaped (approximately rectangular in top view) main section. That is, a plurality of preferably plate-shaped arms are formed or arranged on each longitudinal side of the tongue-shaped main section, which arms are respectively spaced apart from each other in the longitudinal direction of the main section.

[0056] Each arm row has at least one first retaining arm 12 and a second retaining arm 16 , which extend approximately perpendicularly to the plate-shaped / tongue-shaped main section 22 or at an angle of 90°.

[0057] On the side edges of at least two arms of each longitudinal side / arm row, which face each other, latching lugs or latching projections 18 are respectively formed, which lie opposite each other and point toward each other.

[0058] - A first edge extends on the main section 22 between the two first holding arms 12 and a second edge extends between the two second holding arms 16, wherein a cutout or recess 24a is formed on each of the two edges. In other words, a preferably rectangular cutout or recess 24a is formed on the longitudinally spaced end edges of the (plate-shaped / tongue-shaped) main section, which cutout or recess extends in the longitudinal direction. The corners of the preferably rectangular cutout are preferably rounded.

[0059] This means that the clamping clamp has at least four clamping arms 12, 16, which have opposite latching lugs 18, which are formed or arranged on a common base plate (main section) 22 and extend away from each other at an angle of 90° (plus / minus 20°), wherein at least two clamping arms are always arranged at a longitudinal distance from each other on each two opposite longitudinal sides of the base plate 22. At least one preferably rectangular recess 24a, 24b is formed in the base plate 22.
