Description

Technical Field

[0001] This utility model relates to the field of metacarpal reduction stents, and in particular to a metacarpal fracture reduction stent. Background Technology

[0002] Currently, there are certain difficulties and shortcomings in the treatment of hand fractures, particularly in the fixation of broken palms and phalanges. Existing treatment methods may not be able to accurately reduce and fix the broken palm bones, nor can they effectively make the fractured parts of the palm contact each other and maintain stability. It is also difficult to reliably fix each phalanx. After fixation, there may be displacement or rotation, which may affect the healing effect of the fracture and the recovery of hand function. Utility Model Content

[0003] The main purpose of this invention is to address the problem of inaccurate metacarpal alignment.

[0004] To address the above problems, this utility model proposes a metacarpal fracture reduction support, comprising:

[0005] Hollow support rods set in opposite directions;

[0006] The hollow support rod has multiple threaded holes, and a steel nail fastening mechanism is screwed into the inside of each threaded hole.

[0007] The hollow support rod has Kirschner wire insertion holes on its side;

[0008] The bottom of the hollow support rod is connected to a connecting rod, and bolts are provided on the hollow support rod corresponding to the connecting rod. The connecting rod is provided with a fixing elongated hole corresponding to the hollow support rod.

[0009] The fixed elongated hole and the bolt have an adjustment elongated hole through which the relative positions of the hollow support rod and the connecting rod can be adjusted and locked.

[0010] In one embodiment, the steel nail fastening mechanism includes a hollow screw;

[0011] The hollow screw has an insertion and fixing hole inside, and a hollow insertion tapered column is inserted into the insertion and fixing hole;

[0012] Multiple shrinkage slots are provided around the hollow plug-in conical column, and a steel needle insertion hole is provided at the center of the hollow plug-in conical column.

[0013] In one embodiment, the interior of the insertion fixing hole is provided with threads, and the exterior of the hollow insertion tapered column is provided with threads, wherein the hollow insertion tapered column can be screwed into the interior of the insertion fixing hole through the threads.

[0014] In one embodiment, a steel nail is inserted into the inside of the needle insertion hole.

[0015] In one embodiment, a Kirschner wire is inserted into the Kirschner wire insertion hole.

[0016] In one embodiment, the contact surfaces of the connecting rod and the hollow support rod are respectively provided with anti-slip textures.

[0017] Beneficial effects:

[0018] 1. This utility model adopts hollow support rods arranged opposite each other, with Kirschner wire insertion holes on the side and connected at the bottom by a connecting rod. The hollow support rods have fixed elongated holes and bolts on the connecting rods. The two hollow support rods can be pulled closer to each other by adjusting the bolts, so as to achieve contact and locking at the fracture site of the severed hand, and to connect and fix the severed hand.

[0019] 2. The steel nail fastening mechanism of this utility model includes a hollow screw and a hollow insert conical column. The hollow insert conical column has a contraction groove around its perimeter and a steel needle insertion hole inside. By screwing the hollow screw into the threaded hole and the hollow insert conical column into the insertion fixing hole, and inserting the steel nail, the hollow insert conical column is screwed to bring the contraction groove close to the compression fixing steel nail, thereby achieving finger bone fixation.

[0020] 3. Both the inside of the insertion fixing hole and the outside of the hollow insertion tapered column of this utility model are provided with threads, so that the hollow insertion tapered column can be screwed into the insertion fixing hole through the threads, ensuring the stability of the connection.

[0021] 4. The contact surfaces of the connecting rod and the hollow support rod of this utility model are provided with anti-slip textures to increase the friction after they are locked together by bolts, prevent angular rotation, and further improve the fixing effect. Attached Figure Description

[0031] 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.

[0032] To achieve the above-mentioned utility model objectives, such as Figure 1-4 As shown, this utility model provides a metacarpal fracture reduction bracket, including a hollow bracket rod 2 arranged opposite to each other. The hollow bracket rod 2 has multiple threaded holes 1. A steel nail fastening mechanism 3 is screwed into the multiple threaded holes 1. A Kirschner wire insertion hole 4 is opened on the side of the hollow bracket rod 2. A Kirschner wire 10 is inserted into the Kirschner wire insertion hole 4. A connecting rod 5 is connected to the bottom of the hollow bracket rod 2. A fixing elongated hole 7 is opened on the hollow bracket rod 2 corresponding to the connecting rod 5. A bolt 8 is opened on the connecting rod 5 corresponding to the hollow bracket rod 2.

[0033] In this embodiment, when the palm is fractured, the hollow support rods 2 can be placed on the fractured palm, and then the Kirschner wires 10 can be inserted into the fractured palm bone. At this time, the fractured palm can be fixed to the two hollow support rods 2 respectively. Then, the bolts 8 are passed through the inside of the fixing long hole 7 and the adjusting long hole 6, so that the two hollow support rods 2 are pulled closer to each other, and the fractured parts of the palm come into contact with each other. Then, the bolts 8 are tightened, thereby adjusting and locking the relative positions of the hollow support rods 2 and the connecting rods 5, thereby connecting the fractured palm together.

[0034] As a further improvement, such as Figure 1 , 3As shown, the steel nail fastening mechanism 3 includes a hollow screw 32. The hollow screw 32 has an insertion and fixing hole 35 inside. A hollow insertion conical column 31 is inserted into the insertion and fixing hole 35. Multiple shrinkage slots 33 are opened around the hollow insertion conical column 31. A steel needle insertion hole 34 is opened at the center of the hollow insertion conical column 31. A steel nail 9 is inserted into the steel needle insertion hole 34.

[0035] In this embodiment, after the severed hand is reconnected, the hollow screw 32 on the steel nail tightening mechanism 3 can be screwed into the threaded hole 1, and then the hollow insert conical column 31 can be screwed into the insert fixing hole 35. At this time, the steel nail 9 can be inserted into the steel needle insertion hole 34, and then pressed down to insert the steel nail 9 into the corresponding finger bone. Then, the hollow insert column 31 is screwed down to make the shrinkage grooves 33 come closer to each other, thereby squeezing and fixing the steel nail 9, thereby locking the position of the steel nail. In this way, the fixation of each finger bone can be achieved.

[0036] Preferably, the insertion fixing hole 35 has a thread inside, and the hollow insertion tapered post 31 has a thread on the outside, so that the hollow insertion tapered post 31 can be screwed into the insertion fixing hole 35 through the thread.

[0037] Preferably, the contact surfaces of the connecting rod 5 and the hollow support rod 2 are respectively provided with anti-slip textures. When the connecting rod 5 and the hollow support rod 2 are locked and fixed by the bolt 8, the protective textures can increase the friction between the connecting rod 5 and the hollow support rod 2, thereby preventing the angular rotation from occurring after the two are fixed.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
