Description

Technical Field

[0001] This utility model relates to the field of packaging structure technology, and in particular to a packaging structure for homologous bone implant materials. Background Technology

[0002] Bone graft material packaging structures are packaging systems specifically designed to protect bone graft materials (such as implanted bone, bone tissue, or artificial bone). These packaging structures not only need to ensure the integrity and safety of the material, but also need to ensure that it remains sterile, stable, and biocompatible during transportation, storage, and use.

[0003] In existing technologies, allogeneic bone implants are mostly transported by filling the box with cushioning materials such as foam and air cushions to ensure that they are not subjected to external impacts, vibrations, and compressions during transportation, thus avoiding physical damage or deformation caused by improper packaging. However, in actual use, cushioning materials such as foam and air cushions have certain drawbacks. For example, foam and air cushions are often subjected to external impacts or pressures during transportation, causing them to break, dent, or deform. In particular, once the air cushion bag breaks, the cushioning effect will be greatly reduced, causing the allogeneic bone implant to be directly exposed to the impacts and vibrations of the external environment. Therefore, it is necessary to propose a packaging structure for allogeneic bone implant materials to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a packaging structure for homologous bone implant materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A packaging structure for homologous bone implant materials includes a packaging box and a cover plate. The upper end of the packaging box is open, and the cover plate is engaged at this position. A sealing gasket is provided at the contact surface between the cover plate and the packaging box. Sliding rods are fixedly connected to the four corners inside the packaging box. A base plate slides along the outer wall of the sliding rods. Two sets of positioning plates are slidably connected to the end face of the base plate. Limiting grooves are formed at both ends of the positioning plates. Clamping plates are slidably connected within the limiting grooves. A buffer mechanism for cushioning the base plate is installed on the outer wall of the sliding rods.

[0007] Preferably, the buffer mechanism includes a spring sleeved on the outer wall of multiple sets of slide rods, one end of the spring being fixedly connected to the bottom of the packaging box, and the other end of the spring contacting the lower end face of the base plate.

[0008] Preferably, a sliding groove is provided through the end face of the base plate, and a double-ended threaded rod is rotatably connected to the inner wall of the sliding groove. Two sets of sliders are threadedly connected to the threaded section of the double-ended threaded rod, and are respectively fixedly connected to two sets of positioning plates.

[0009] Preferably, a connecting rod is fixedly connected to the inner wall of the limiting groove, and the clamping plate is slidably connected to the outer wall of the connecting rod, with the outer wall of the clamping plate being Z-shaped.

[0010] Preferably, a second spring is sleeved on the outer wall of the connecting rod, one end of the second spring is fixedly connected to the inner wall of the limiting groove, and the other end of the second spring is fixedly connected to the clamping plate.

[0011] Preferably, the lower end face of the cover plate is fixedly connected to multiple sets of top rods, and their positions correspond to the positions of multiple sets of sliding rods. The top rods are in contact with the end faces of the sliding rods. A rotating block is rotatably connected inside the base plate and is coaxially fixedly connected to the double-ended threaded rod.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the adjustment of the clamping plate and the positioning plate, makes the implanted material more stable and precise in the packaging device. Whether the implanted material is clamped from the side or both ends, it can effectively avoid displacement or damage caused by external impact or vibration, and ensure that the implanted material is always in a stable state during the packaging process.

[0014] 2. This utility model uses a spring as a buffer structure, which can effectively absorb external impact energy and alleviate the impact force on the packaging box. When the spring is compressed, it absorbs energy and pushes the bottom plate back to its original position during the recovery process, ensuring that the internal structure of the packaging box is not damaged. This protects the implanted material from excessive pressure or vibration, and improves the shock resistance and service life of the packaging device. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A packaging structure for homologous bone implant materials includes a packaging box 1 and a cover plate 2. The upper end of the packaging box 1 is open and the cover plate 2 is engaged there. A sealing gasket 4 is provided at the contact surface between the cover plate 2 and the packaging box 1. Slide rods 5 are fixedly connected to the four corners inside the packaging box 1. A base plate 6 is slidably connected to the outer wall of the slide rods 5. Two sets of positioning plates 10 are slidably connected to the end face of the base plate 6. Limiting grooves 13 are opened at both ends of the positioning plates 10. Clamping plates 11 are slidably connected in the limiting grooves 13. A buffer mechanism for buffering the base plate 6 is installed on the outer wall of the slide rods 5.

[0022] Specifically, by sliding the two sets of positioning plates 10, the homologous bone implant material can be clamped and positioned from both sides. With the adjustment of the positions of the two sets of clamping plates 11, the homologous bone implant material can be clamped and fixed from both ends, thereby avoiding displacement or deformation caused by impact or vibration. At the same time, it can be flexibly adjusted according to the size of the homologous bone implant material. Compared with the positioning and cushioning methods of foam and air cushion, this device will not be subject to pressure or breakage problems, and can be reused multiple times.

[0023] The buffer mechanism includes a spring 7 sleeved on the outer wall of multiple sets of slide rods 5. One end of the spring 7 is fixedly connected to the bottom of the inner packaging box 1, and the other end of the spring 7 is in contact with the lower end face of the base plate 6.

[0024] Specifically, when an external impact acts on the packaging box 1, the spring 7 will compress and absorb the impact energy, and then push the bottom plate 6 back to its original position through elastic restoring force, effectively preventing the implanted material from being subjected to excessive external impact or vibration.

[0025] A sliding groove 8 is provided through the end face of the base plate 6. A double-threaded rod 9 is rotatably connected to the inner wall of the sliding groove 8. Two sets of sliders 12 are threadedly connected to the threaded section of the double-threaded rod 9 and are fixedly connected to two sets of positioning plates 10 respectively. A connecting rod 14 is fixedly connected to the inner wall of the limiting groove 13. A clamping plate 11 is slidably connected to the outer wall of the connecting rod 14. The outer wall of the clamping plate 11 is Z-shaped. A second spring 15 is sleeved on the outer wall of the connecting rod 14. One end of the second spring 15 is fixedly connected to the inner wall of the limiting groove 13, and the other end of the second spring 15 is fixedly connected to the clamping plate 11.

[0026] Specifically, by rotating the double-ended threaded rod 9, the two sets of positioning plates 10 can be driven to slide towards or relative to each other, thereby flexibly adjusting the position of the positioning plates 10. In conjunction with the sliding of the clamping plate 11, it can flexibly position and clamp implanted materials of different sizes. The setting of the second spring 15 can ensure that the clamping plate 11 is stably attached to the end of the implanted material when clamping, further improving the stability of the positioning of the implanted material.

[0027] Multiple sets of top rods 3 are fixedly connected to the lower end face of the cover plate 2, and their positions correspond to the positions of multiple sets of sliding rods 5. The top rods 3 are in contact with the end faces of the sliding rods 5. A rotating block 16 is rotatably connected inside the base plate 6 and is coaxially fixedly connected to the double-headed threaded rod 9.

[0028] Specifically, the end of the slide bar 5 is not limited, so the bottom plate 6 can be directly pulled away, which improves the convenience of the device when in use. After the cover plate 2 is engaged with the upper end of the packaging box 1, the top rod 3 can guide the sliding of the bottom plate 6 to prevent it from falling off.

[0029] In this invention, the device is used as follows: When the operator uses the packaging device, the implant material is placed at the center of the base plate 6. Then, the rotating block 16 is rotated, driving the double-ended threaded rod 9 to rotate synchronously. The two sets of sliders 12 on its threads drive the positioning plate 10 to slide towards each other until they contact the two sides of the implant material, achieving side positioning. Then, the clamping plate 11 is pulled outward, forcing the second spring 15 to compress until the clamping plate 11 contacts both ends of the implant material, achieving clamping and positioning of the implant material from both ends. The second spring 15 maintains a uniform clamping force, preventing displacement or damage to the implant material due to external impact or vibration. At the same time, the base plate 6, through the adjustment of the double-ended threaded rod 9 and slider 12 in the slide groove 8, ensures the flexibility and accuracy of the clamping action, allowing implant materials of different sizes to be adapted and adjusted, and to be well fixed in the packaging box 1.

[0030] When an external impact is applied to the packaging box 1, spring 7, through its elastic properties, absorbs the impact energy when compressed. This energy absorption process is gradual; spring 7 mitigates the direct transmission of the impact force through compression, reducing the impact force on the interior of the packaging box 1 and protecting the embedded materials from excessive pressure or vibration. Once the impact force dissipates, spring 7, due to its elastic restoring force, pushes the base plate 6 back to its original position, thereby ensuring the stability of the internal structure of the packaging box 1.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
