Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a personalized bone graft kit. Background Technology

[0002] Currently, commonly used methods for femoral neck bone grafting in clinical practice include bone flap transplantation and bone marrow transplantation. The former includes vascularized bone flaps and muscularized bone flaps. Its advantages are that it provides bony support to the defect site and has its own blood supply; its disadvantages include the need for open surgery, damage to the donor site, donor shape mismatch, increased surgical scope, time, and blood loss, and also requires a high level of microsurgical skill from the surgeon. The latter method allows for minimally invasive procedures, but it cannot provide effective bony support and cannot precisely locate the defect site. These limitations significantly restrict the application of bone grafting in the treatment of femoral neck fractures.

[0003] Bone defects requiring grafting are typically large, and in such cases, cancellous bone grafting may not provide reliable stability. Structural bone grafting can provide rigid support. Furthermore, we aim for the grafted bone to remain fixed in its target position long-term, preventing displacement or loss due to movement or stress.

[0004] Therefore, it is necessary to provide a personalized bone graft kit to solve the above problems. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the purpose of this application is to provide a personalized bone graft kit to achieve the effect of assisted positioning.

[0006] The technical solution adopted by this application to solve its technical problem is: a personalized bone graft kit, including a guide plate and a titanium mesh. The guide plate has several limiting holes on its lower side, and a movable ball is movably disposed in each of the limiting holes. The movable ball is provided with a guide hole, and the titanium mesh is cylindrical.

[0007] Furthermore, the limiting holes are arranged in an X-shape.

[0008] Furthermore, the upper side of the guide plate is provided with several positioning holes, and screws are installed in each positioning hole.

[0009] Furthermore, one end of the titanium mesh is provided with a blade-shaped head.

[0010] Furthermore, the outer wall of the titanium mesh is provided with threads.

[0011] The beneficial effects of this utility model are:

[0012] 1. The movement of the movable ball within the limiting hole allows the user to easily adjust the direction of the guide hole, which is used to guide the guide needle for bone graft positioning.

[0013] 2. By preserving the bone tissue obtained during the pore-reaming process, the bone tissue can then be filled into the titanium mesh, which can promote bone metabolism. Attached Figure Description

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] In this invention, unless otherwise stated, the orientations used, such as "up" and "down," generally refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this invention.

[0024] like Figure 1-3 As shown, this application provides a personalized bone graft kit, including a guide plate 1 and a titanium mesh 2.

[0025] The upper side of the guide plate 1 is provided with several positioning holes 11, and each positioning hole 11 is provided with a screw 12. The lower side of the guide plate 1 is provided with several limiting holes 13, which are arranged in an X shape. Each limiting hole 13 is movably provided with a movable ball 14, and each movable ball 14 is provided with a guide hole 15.

[0026] The titanium mesh 2 is cylindrical, with a blade-shaped head 21 at one end and threads 22 on the outer wall of the titanium mesh 2.

[0027] Screw 12 is used to fix guide plate 1 to the lateral side of the greater trochanter of the bone through positioning hole 11. Then, as needed, a virtual reduction and reconstruction of the defect model is performed, and the main location of the defect is recorded. Next, a guide pin is inserted into the guide hole 15 below according to the defect direction to complete the bone graft positioning. Afterwards, the guide plate is removed, and a hollow drill is used to open the bone graft channel, while preserving the bone obtained during hole enlargement.

[0028] During the above process, the movement of the movable ball 14 within the limiting hole 13 allows the user to easily adjust the direction of the guide hole 15. The guide hole 15 is used to guide the guide pin for bone graft positioning.

[0029] The blade-shaped head 21 and threads 22 facilitate the easy advancement of the titanium mesh 2 into the target bone graft area during implantation, providing rigid support to the bone. The threads 22 also ensure the titanium mesh 2 remains permanently fixed in its target position, preventing displacement or loss due to movement or stress. The bone tissue obtained using the hollow drill can be used to fill the titanium mesh, or PRP and other biological agents that promote bone metabolism can be injected.
