Abstract
Description
Technical Field
[0001] This utility model relates to the field of bone defect repair technology, specifically a bone defect repair scaffold. Background Technology
[0002] Bone defects refer to the destruction of the structural integrity of bone. Common causes include trauma, infection, bone tumors, and osteonecrosis. Currently, the main clinical treatment for large bone defects caused by open fractures and bone tumors is filling and repair.
[0003] Publication number CN221904229U discloses a bone defect repair scaffold, which includes a mesh-like inner support frame and a protective ring around the periphery of the mesh-like inner support frame. The protective ring is circular in shape. This technical solution uses the circular protective ring to protect the internal mesh-like inner support frame. The protective ring is removed during actual use.
[0004] However, the top and bottom sides of the mesh-like inner support frame remain exposed. The protective ring cannot protect the top and bottom sides of the mesh-like inner support frame, which means that when the top and bottom sides encounter accidental collisions or compression, the mesh-like inner support frame is still prone to deformation and damage.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] See Figures 1-4 This utility model provides the following two technical solutions: First embodiment: A bone defect repair scaffold, comprising a repair scaffold body 1 and a protective component; The protective components include an upper rubber sleeve 2 and a lower rubber sleeve 3, which are respectively fitted on the upper and lower sides of the repair bracket body 1. The upper rubber sleeve 2 is located inside the upper protective cover 4, and the lower rubber sleeve 3 is located inside the lower protective cover 5. The upper rubber sleeve 2 and the lower rubber sleeve 3 are in contact with each other on opposite sides, and the upper protective cover 4 and the lower protective cover 5 are in contact with each other on opposite sides. Through the upper rubber sleeve 2 and the lower rubber sleeve 3, the upper protective cover 4 and the lower protective cover 5 can avoid friction and excessive compression of the internal repair bracket body 1. Then, the upper protective cover 4 and the lower protective cover 5 can protect against accidental collisions and compression from the outside. The upper protective cover 4 is evenly provided with upper protruding plates 6, the lower protective cover 5 is evenly provided with lower protruding plates 7, and the upper protruding plate 6 is provided with a rod 8 that penetrates the lower protruding plate 7. The lower protective cover 5 is equipped with a fixing device for fixing each plug rod 8, which can fix the upper protective cover 4 and the lower protective cover 5 together to ensure that the repair bracket body 1 will not be deformed or damaged before use.
[0018] The fixing device includes a support bearing 10 located on the outside of the lower protective cover 5. A rotating ring 11 is connected to the outside of the support bearing 10. Each rotating ring 11 has an L-shaped arc-shaped protrusion 12 at its top. Each insertion rod 8 has an arc-shaped through groove 9, and the arc-shaped protrusion 12 is inserted into the arc-shaped through groove 9. After the upper protective cover 4 and the lower protective cover 5 are connected by the insertion rods 8, the rotating ring 11 is rotated so that it rotates along the support bearing 10, thereby rotating all the arc-shaped protrusions 12 and inserting them into the arc-shaped through grooves. At the same time, all the insertion rods 8 are fixed so that the insertion rods 8 cannot move upward, thus preventing the upper protective cover 4 and the lower protective cover 5 from separating.
[0019] The upper and lower ends of the outer side of the rotating ring 11 are provided with arc-shaped transition parts to prevent the upper and lower ends of the outer side of the rotating ring 11 from being too sharp, so that the hands will not be scratched when rotating by hand.
[0020] The outer side of the rotating ring 11 is provided with a protrusion 13, and the protrusion 13 is provided with a limiting hole. The outer side of the lower protective cover 5 is provided with a limiting member connected to the limiting hole, which can fix the rotating ring 11 and improve the stability of the connection between the upper protective cover 4 and the lower protective cover 5.
[0021] The limiting component includes a connecting rod 14 mounted on the lower protective cover 5. A vertical rod 15, which is inserted into a limiting hole, runs vertically through the connecting rod 14. A connecting ring 16, located above the protrusion 13, is mounted on the vertical rod 15. A return spring 18 is provided between the connecting ring 16 and the connecting rod 14. Before rotating the rotating ring 11, the vertical rod 15 is pulled up, causing the connecting ring 16 to move upward and compress the return spring 18. When the protrusion 13 is aligned with the vertical rod 15, the arc-shaped protrusion 12 also enters the arc-shaped through groove 9. At this point, the vertical rod 15 can be released, causing the elastic force of the return spring 18 to drive the connecting ring 16 downward, which in turn drives the vertical rod 15 downward to insert into the limiting hole, fixing the protrusion 13 and preventing the rotating ring 11 from rotating. This ensures that the arc-shaped protrusion 12 cannot rotate, improving the stability of the connection between the upper protective cover 4 and the lower protective cover 5.
[0022] The second embodiment differs from the first embodiment in that the top of the vertical rod 15 is provided with a handle 17 located above the connecting rod 14, which facilitates pulling the vertical rod 15.
[0023] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0024] In use, place the repair bracket body 1 into the lower rubber sleeve 3, and then place the upper protective cover 4 on the lower protective cover 5. At this time, the repair bracket body 1 is positioned between the upper rubber sleeve 2 and the lower rubber sleeve 3. Then rotate the rotating ring 11 to make the arc-shaped protrusion 12 enter the arc-shaped through groove 9. Then release the handle 17 to make the vertical rod 15 enter the limiting hole of the protrusion 13, which can fix the rotating ring 11, so that the upper protective cover 4 and the lower protective cover 5 will not separate, thus providing full protection for the repair bracket body 1. When actually using it, first pull the handle 17 up, and then rotate the rotating ring 11 to release the fixation between the upper protective cover 4 and the lower protective cover 5. Then remove the upper protective cover 4 and the lower protective cover 5 respectively.
