[0002] An external fixator is an in vitro fixation device that connects each end of the fracture to one or more longitudinal rods (tubes) and / or rings through metal bone screws to achieve the effect of stabilization and reduction. It is often used in orthopedic treatment and is suitable for various cases of open fractures of the limbs, old fractures, etc. Common external orthopedic stents are unilateral stents. After the unilateral stent is used, the structure is unstable and easily causes secondary injuries. Some are annular stents. When the annular stent is used, the structure can be stabilized by adding an oblique rod. However, when the existing unilateral stents and annular stents are used, the connecting rod is fixed in length and cannot be adjusted in length according to demand, which leads to the need to replace connecting rods of different lengths in actual application, which is time-consuming and labor-intensive. At the same time, the two ends of the oblique rod in the annular stent are generally fixed on the connecting rod. When the annular frame shakes, the connecting rod and the oblique rod will also shake, and the structure is not very stable. Therefore, the present application provides a combined orthopedic external fixator to solve the above technical problems. Utility Model Content

[0022] Example

[0023] like Figure 1 As shown, a combined orthopedic external fixation bracket includes a first frame 1 and a second frame 2 arranged relative to the first frame 1. A connecting rod 5 is arranged between the first frame 1 and the second frame 2, and the two ends of the connecting rod 5 are respectively connected to the first frame 1 and the second frame 2 through a first fixing member 3. A bone needle holding member 7 for clamping a bone needle is arranged on the first frame 1 and the second frame 2, and the bone needle holding member 7 is connected to the first frame 1 or the second frame 2 through a second fixing member 4. A first adjustment hole 10 and a second adjustment hole 11 are arranged on the surface of the first frame 1 and the second frame 2, and the penetration directions of the first adjustment hole 10 and the second adjustment hole 11 are perpendicular to each other, and the two ends of the connecting rod 5 pass through the first adjustment hole 10. The first fixing member 3 and the second fixing member 4 adopt existing structures according to needs, including but not limited to bolt and nut pairs.

[0024] like Figure 2As shown, a combined orthopedic external fixator also includes an oblique rod 9, and the two ends of the oblique rod 9 are respectively connected to the first frame 1 and the second frame 2 through an oblique rod support 8, and the oblique rod support 8 passes through the second adjustment hole 11. One end of the oblique rod 9 is connected to the first frame 1, and the other end of the oblique rod 9 is connected to the second frame 2. At this time, the first frame 1, the connecting rod 5, and the oblique rod 9 form a triangle, making the structure more stable. The oblique rod 9 can be set to 2, and the two oblique rods 9 are arranged in an "X" shape on both sides of the connecting rod 5, which can also make the structure more stable.

[0025] like Figure 1 As shown, the connecting rod 5 includes a connecting portion 5-1, an adjusting portion 5-2, and a locking buckle 5-3. Two connecting portions 5-1 are provided, and an adjusting portion 5-2 is provided between the two connecting portions 5-1. The adjusting portion 5-2 and the connecting portion 5-1 are telescopically arranged. A locking buckle 5-3 with a locking function is provided at the connection between the adjusting portion 5-2 and the connecting portion 5-1. When the locking buckle 5-3 is released, the two connecting portions 5-1 move toward the adjusting portion 5-2, so that the adjusting portion 5-2 shrinks into the inside of the connecting portion 5-1, and the length of the connecting rod 5 becomes shorter; the two connecting portions 5-1 move in the opposite direction of the adjusting portion 5-2, so that the adjusting portion 5-2 extends out from the inside of the connecting portion 5-1, and the length of the connecting rod 5 becomes longer, thereby adjusting the connecting rod 5, and there is no need to replace connecting rods 5 of different lengths, which saves time and effort. The locking buckle 5-3 adopts an existing structure according to demand.

[0026] like Figure 3 As shown, the bone needle holder 7 includes a support frame 13, and the support frame 13 is connected to the first frame 1 or the second frame 2 through a support rod 6, and the support rod 6 passes through the first adjustment hole 10. A bone needle hole 12 is arranged inside the support frame 13, and a pressure plate 14 is arranged on one side of the bone needle hole 12, and a bolt 15 is arranged on the outer side of the pressure plate 14. By rotating the bolt 15, the bolt 15 presses against the pressure plate 14 to make it move along the support frame 13, so as to tighten the bone needle in the bone needle hole 12.

[0027] like Figure 4 As shown, a bone needle is arranged inside the bone needle holder 7, and a depth scale line 18 for indicating the depth is arranged on the surface of the bone needle. An anti-slip line 17 is arranged on the surface of the bone needle that contacts the bone needle holder 7, and a protective cap 16 is arranged at the end of the bone needle for protection. The anti-slip line 17 can be set as a structure such as a thread line that can prevent the movement of the bone needle. By rotating the bolt 15, the pressure plate 14 is pressed against the bone needle in the bone needle hole 12, and the anti-slip line 17 can effectively prevent the bone needle from moving.

[0028] like Figure 5 and Figure 6 As shown, the first frame 1 or the second frame 2 includes two identical annular frames 20 , and the two annular frames 20 are connected by a connecting buckle 19 .

[0029] In the present application, the annular frame 20, the first fixing member 3, the support rod 6, the second fixing member 4, the bone needle supporting member 7, the inclined rod 9, the bone needle and other structures are all detachable and can be freely combined and used. The above embodiment is only one of the embodiments. When using, the number of each structure used is not limited, and it can be selected according to actual needs.

[0030] Therefore, the utility model adopts a combined orthopedic external fixator of the above structure, is provided with a connecting rod with adjustable length, and fixes the two ends of the oblique rod to the annular frame to increase stability, thereby solving the problem that the orthopedic external fixator in the prior art cannot be adjusted and has poor stability.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
