Description

Technical Field

[0001] This utility model relates to medical devices, and in particular to a fixation structure for free bone fragments. Background Technology

[0002] Comminuted fracture fragments (free bone fragments) at the fracture ends often cannot be effectively fixed. Currently, it is common practice to use a single wire to bind the free bone fragments, which often causes the wire to shift vertically, thus changing the position of the free bone fragments. Alternatively, multiple wires can be used to bind the free bone fragments, which is time-consuming and laborious, increases friction between the wires and the bone, and is detrimental to the patient's health. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the problems of displacement and excessive friction that often occur when using steel wire to fix free bone blocks, the present invention provides a fixation structure for free bone blocks.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a fixation structure for free bone blocks, including a main steel plate, and one or more connecting members are provided on the main steel plate.

[0005] One end of the connector is the mounting end, and the other end is the fixing end. The mounting end and the fixing end are connected by a connecting section. The mounting end is fixed to the patient's bone by mounting bolts through the mounting holes on the main steel plate. The connecting section can be bent freely according to the location of the free bone fragment. The fixing end is equipped with a positioning bolt, which fixes the free bone fragment at the bone fracture site.

[0006] Furthermore, the mounting end is circular, and the inner ring of the mounting end is a smooth through hole.

[0007] Furthermore, the fixed end is circular, and the inner ring of the fixed end is a threaded hole with internal threads.

[0008] Furthermore, multiple connectors can be installed on a single mounting hole on the main steel plate, and the multiple connectors are stacked and installed through mounting ends.

[0009] Furthermore, an identification hole is provided on the side of the connecting segment near the fixed end.

[0010] The beneficial effects of this utility model are: the free bone block fixing structure of this utility model changes the previous method of binding free bone blocks with steel wires. It adopts a connecting piece and main steel plate installation structure to fix free bone blocks and broken bones. The structure is simpler, the fixing effect is better and there is almost no additional wear. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Figures 1 to 4 The free bone fragment fixation structure shown includes a main steel plate 1, on which one or more connectors are mounted. Typically, there are one or two connectors. One end of each connector is a mounting end 2, and the other end is a fixing end 3. A connecting section 4 is located between the mounting end 2 and the fixing end 3. The mounting end 2 is fixed to the patient's bone via mounting bolts 6 through mounting holes 5 on the main steel plate 1. The mounting holes 5 are already present on the existing main steel plate 1, so no additional holes need to be designed on the main steel plate 1. The connecting section 4 is made of soft metal and can be bent at any angle according to the location of the free bone fragment to match the installation angle of the positioning bolts 7. After the connecting section 4 is adjusted, the positioning bolts 7 are installed in the fixing end 3, and the positioning bolts 7 fix the free bone fragment at the fracture site.

[0019] To allow for a reasonable gap between the free bone fragment and the fractured bone after they are secured, the mounting end 2 is circular, and its inner ring is a smooth through hole. To better fix the free bone fragment, the fixing end 3 is circular, and its inner ring is a threaded hole with internal threads. When there are many free bone fragments, multiple connectors can be installed on a single mounting hole 5 on the main steel plate 1, and the multiple connectors are stacked through the mounting end 2. To facilitate identification by medical staff, an identification hole 8 is provided on the side of the connecting section 4 near the fixing end 3. The identification hole 8 not only serves an identification function, but also allows blood to flow on both sides of the connector when it is in contact with the bone, including the free bone fragment, thus balancing the pressure on both sides.

[0020] 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.
