[0093] FIG. 1 shows a first carrier 1 according to the invention, which is suitable for receiving an implant in the form of a bone plate not shown here (see FIG. 6). The carrier 1 contains an implant receptacle 3, an elastic element in the form of a spring 10 and a stopper 11, which are shown in detail in FIGS. 2 to 4.
[0094] According to FIG. 2, the implant receptacle 3 is substantially elongated along a longitudinal axis 4 and has a first portion 5 and a second portion 6. The first portion 5 includes a shaft 7 for receiving one or more implants at respective recesses of the implant(s). On the side of the first portion 5, the implant receptacle 3 has a rounded end 19 for receiving the implant. The second portion 6 includes a thread 14, for example an M3 thread, a first attachment portion 8 of conical shape for fastening to a holding section of a container not shown here (see FIG. 6 for this), and a cross-sectional thickening in the form of a head 15. A thread undercut 29 is located between the thread 14 and the attachment portion 8. The first attachment portion 8 is arranged along the longitudinal axis 4 of the implant receptacle 3 between the thread 14 and the cross-sectional thickening 15. As shown in FIG. 1, the stopper 11 is attached to the second portion 6 of the implant receptacle 3 by means of the thread 14. As is also evident from FIG. 1, the implant receptacle 3 extends along the longitudinal axis 4 in the direction of the first portion 5 beyond the spring 10, and the second attachment section 12 of the spring 10 is clamped between the stopper 11 and the head 15 of the implant receptacle 3.
[0095] The spring 10 shown in FIG. 3 extends along the longitudinal axis 4 of the implant receptacle 3 (see FIG. 1). The spring 10 is elastic perpendicular to this direction and arranged to be elastically deformed when the implant is removed (see FIG. 6). This provides a force component perpendicular to the longitudinal axis 4, which allows an implant held on the implant receptacle 3 to be secured. The spring 10 thus serves as a loss prevention device.
[0096] In FIG. 3, it can further be seen that the spring 10 has a second attachment section 12 with a recess 13 through which the implant receptacle 3 can be passed, allowing the spring 10 to be attached to the implant receptacle 3 (see FIG. 1). The second attachment portion 12 has two first wing-shaped projections 16. With the first projections 16, the spring 10 can be aligned with a holding section of a container not shown here (see FIG. 8). In addition, the second attachment portion 12 has two second projections 17 with which the stopper 11 can be aligned with the spring 10 (see FIG. 5). The first projections 16 and the second projections 17 extend in opposite directions with respect to the longitudinal axis 4 of the implant receptacle 3. In an end region 20, the spring 10 is curved in the direction of the first portion 5 of the implant receptacle 3 in such a way that the implant is secured against accidental loss (see in this respect FIGS. 1 and 6). At one end 21, the spring 10 is bent away in the direction of the first portion 5 of the implant receptacle 3 in such a way that an implant 2 elastically deforms the spring 10 during insertion.
[0097] The stopper 11 shown individually in FIG. 4 has a stop 18 for the spring 10. The stop 18 is shaped and arranged to prevent plastic deformation of the spring 10, in particular overbending. Furthermore, the stopper 11 has an opening 28 through which the spring 10 can be passed.
[0098] FIG. 5 shows the carrier 1 attached to a holding section 9 of a container in a perspective view.
[0099] FIG. 6 shows a set according to the invention with the first carrier 1 according to the invention and a bone plate 2. This set is attached to the holding section 9 of the container.
[0100] FIGS. 7a and 7b show a section of a retaining section 9 of a container not shown as a whole here, namely in FIG. 7a without a bone plate and in FIG. 7b with a bone plate 2. The retaining section 9 has an alignment recess 23 for the first projections 16 of the spring 10. The alignment recess 23 is composed of a central, circular region 23a and two substantially rectangular receiving regions 23b connected thereto and lying opposite one another. In the circular region 23a, the implant receptacle 3 is held and centered by means of the conical attachment portion 8 shown in FIG. 2. The first extensions 16 of the spring 10 are held in the receiving regions 23b. The bone plate 2 is also held by another implant receptacle 3′, which is identical to the implant receptacle 3 and is attached to the holding section 9 in the same way as shown in FIG. 6.
[0101] In FIG. 8, a first container 50 according to the invention is shown with several such sets. As can be seen from the figure, each carrier holds a bone plate together with a respective further implant receptacle.
[0102] FIG. 9 shows an elastic locking element 22 for the carrier 1 according to FIGS. 1 to 4. The locking element 22 has a body 25 with a receiving opening 26 through which the shaft 7 of the implant receptacle 3 can be passed (see FIG. 10). The body 25 further comprises a notch 27 in which the spring 10 engages. In this way, the locking element 22 can be secured to the implant receptacle 3 (see FIG. 10). The locking element 22 prevents bone plates from being placed on the implant receptacle 3.
[0103] The aforementioned FIG. 6 shows a set consisting of a carrier 1 and a bone plate 2 with two recesses 13. The implant receptacle 3 of the carrier 1 is received in a circular area 23a of the holding section 9 and is guided through one of the recesses 13. Through this, the bone plate 2 is held.
[0104] FIG. 8, which has also already been mentioned, shows a first container 50 according to the invention for bone plates 2. The container 50 has a base 24 with a holding section, wherein a set according to FIG. 6 is attached directly to the holding section (i.e. without any components arranged in between). The shafts 7 extend perpendicular to the base 24.
[0105] FIGS. 11a and 11b show a second carrier 1 according to the invention in a perspective view and a side view. This carrier 1 differs from the one shown in FIGS. 1 to 4 essentially in the spring 10, which is shown separately in FIG. 12. In its end region 20, the spring 10 is curved in the direction of the implant receptacle 3 not only at one point, but at two points. This allows two implants to be held at a distance from each other, which also allows the implants to be cleaned and, in particular, sterilized more easily.
[0106] The second carrier 1 according to the invention as shown in FIGS. 11a and 11b is shown in FIG. 13 together with two bone plates 2 held thereon. The carrier 1 is also attached here to a holding area 9 of a container.
[0107] A further embodiment is shown in FIGS. 14a and 14b. This carrier 1 contains two implant receptacles 3 and a spring 10. As can be seen in FIG. 14b, the implant receptacle 3 shown there on the right also functions as a stopper 11 for the spring 10. This carrier 1 can accommodate a single bone plate held by one or both implant receptacles 3, or two bone plates each held by one of the two implant receptacles 3.
[0108] FIG. 15 shows a securing element 103 of another carrier according to the invention, but which is intended to receive one or more screws. The securing element 103 contains a central area 117 with several recesses 105, through which a screw can be removed (see FIG. 17b), as well as several elastically formed feet 111. In a first end area 109, the securing element 103 has a first spring element 108 formed in one piece. Opposite the first end region 109, the securing element 103 has a second end region 118, also integrally formed, which forms a second spring element and also has elastically formed feet 111. In the second end region 118, the securing element 103 is inscribed by a laser marking 116. An actuating element 119 extending away from the feet 111, i.e. upwardly, is formed in the outermost end of the second end region 118.
[0109] FIG. 16a shows a section of a container 114 according to the invention with a holder 102. The holder 102 has a plurality of receptacles 104, each for a screw. The receptacles 104 are arranged along a straight line 107. The recesses 105 of the securing element 103 correspond to the receptacles 104 of the retainer 102. Further, the retainer 102 has elongated retainer recesses 112 arranged along a line parallel to the line 107. In addition, the bracket 102 has a plurality of contoured retainer apertures 120.
[0110] FIG. 16b includes a detailed view of one of the contoured receiving apertures 120. The receiving aperture 120 includes a rectangular passageway region 121 having a longer side and a shorter side, the longer side extending parallel to the line 107. On either side of the passageway region 121, a wedge-shaped recess 122 with an inclined upper sliding surface 123 is provided on the upper side of the retainer 102, and a wedge-shaped projection 124 with a lower sliding surface 125, a vertically extending detent surface 126, and a step 127 formed therebetween is provided on the lower side of the retainer 102.
[0111] FIGS. 17a and 17b show the container 114 with the retainer 102 and a securing element 103. A screw 101 is inserted in each of the receptacles 104. The first spring element 108 is inserted in an opening in the bracket 102, and the feet 111 of the second end portion 118 are inserted in two adjacent contoured receiving openings 120. The feet 111 of the middle portion 117 extend in the direction of the bracket 102 and are engaged in the bracket recesses 112. The longitudinal extent of the feet 111 of the center portion 117 in the direction of the line 107 is less than the longitudinal extent of the retainer recesses 112 in that direction. This has the effect of movably connecting the securing element 103 to the holder 102. In this way, it can be moved, i.e. translationally moved, from a first position P1 shown in FIG. 17a to a position P2 shown in FIG. 17b. This is made possible by the fact that the feet 111 are displaceable along an edge 115 of the holder when engaged. The edges 115 are formed by the elongated bracket recesses 112 of the bracket 102.
[0112] In the first position P1 shown in FIG. 17a, the screws 101 are secured by the securing element 103. This is because, since the recesses 105 of the securing element and the receptacles 104 of the holder 102 are not aligned with each other, the screws 101 cannot be removed along a removal direction 106 that coincides with the longitudinal axis of the screw 101. This becomes possible only in the second position P2 shown in FIG. 17b. In this second position P2, the screw 101 can be removed from the receptacle 104 through the recess 105 along the removal direction 106.
[0113] The first spring element 108 is configured and arranged to hold the securing element 103 in the first position P1. FIGS. 17a and 17b also reveal a releasable latching device 110 that can latch and thus fix the securing element 103 in the second position P2, once the securing element 103 reaches the second position P2.
[0114] FIGS. 18a and 18b show in detail, in lateral views, how the movement of the securing element 103 is achieved by cooperating with a lid 113 of the container 50. In the second position P2 shown in FIG. 18a, the feet 111 of the first end portion 118 are pressed against the latching surfaces 126 by the first spring element 108. In this second position P2, the lid 113 is not yet fully attached, so that there is not yet any contact with the actuating element 119.
[0115] This contact does not occur until the lid 113 is fully fitted, as shown in FIG. 18b. The cover 113 presses down the actuating element 119. This moves the feet 111 of the second end portion 118 over the step 127, so that the securing element 103 moves from the second position P2 to the first position P1 by the spring force generated by the first spring element 108. In the process, the feet 111 of the second end portion 118 slide along the sliding surfaces 125 of the contoured receiving openings 120.
[0116] After the lid 113 is lifted off, the securing element 103 remains in the first position P1 due to the force caused by the first spring element 108. By exerting a force directed parallel to the line 107 on the actuating element 119, the feet 111 can be moved along the sliding surfaces 123, 125 up to above the step 127, whereby the second position P2 is reached and the feet 111 of the second end portion 118 move upwards and thus back to the latching position due to the resilient action of the first end portion 118.
[0117] The transfer of the securing element 103 from the second position P2 to the first position P1 can of course also be performed manually, i.e. without the action of the cover 113.
[0118] FIG. 19 shows a first container 114 according to the invention with a holder 102 and a plurality of carriers 100, each of which comprises a securing element 103. Here, some of the securing elements 103 are in the first position P1 and the remaining ones are in the second position P2.
[0119] In FIG. 20, the container 114 is shown together with a lid 113 with which it can be closed.
[0120] FIGS. 21 to 24 show a further example of an embodiment. The securing elements 103 of the carriers 100 shown in FIG. 23 on the left are in the second position P2, in which the securing elements 103 protrude beyond the edge of the container 114. The securing elements 103 of the carriers 100 shown in FIG. 23 on the right are in the first position P1 and do not protrude beyond the edge of the container 114. As long as at least one of the securing elements 103 is in the second position P2, no lid 113 can be placed on the container 114. This is only possible when the securing elements 103 are transferred to the first position P1, in which they do not protrude beyond the edge of the container 114. Thus, the screws 101 are always secured against falling out when the lid 113 is in place.
[0121] The carrier 1 according to the invention for a bone plate 2 shown in FIG. 25 contains two leaf springs 28 which extend substantially along the common longitudinal axis 4, but which are spaced apart from each other by a greater distance in a central region. When a bone plate 2 with a recess is placed over the leaf springs 28, the leaf springs 28 are pressed against each other and the bone plate 2 can be slid over the central region. After the bone plate 2 has passed the central area, the leaf springs 28 spring apart again and thus secure the bone plate 2 against accidental falling out.
[0122] FIG. 26 shows a spring 10 of a further carrier 1 according to the invention. The spring 10 has a lug 41 with an end 42 that is guided in a rail 43. One end 44 of the rail 43 forms a stop which prevents excessive bending of the spring 10.
[0123] FIGS. 27a and 27b show another carrier 1 for a bone plate. The carrier 1 includes a shaft 31 for receiving the bone plate at one of its recesses. At a first, here lower end 32, the shaft 31 has means for attachment to a retaining section 9 of a container. Further, the carrier 1 includes a locking element 34 pivotally disposed at a second, here upper, end 33 of the shaft 31 opposite the first end 32 of the shaft 31. The locking element 34 can be pivoted to a receiving position shown in FIG. 27a and to a locking position shown in FIG. 27b. In the receiving position, the bone plate with the recess can be moved over the locking element 34 onto the shaft 31. By pivoting the locking element 34 into the locking position, the locking element 34 prevents removal of the bone plate.
