Description

Technical Field

[0001] This utility model relates to the field of metal bone plate technology, and more specifically, to a metal bone plate for orthopedic use. Background Technology

[0002] Bone plates have been used as internal fixation devices for over a hundred years. Locking bone plates are currently the most commonly used internal fixation devices for treating fractures both domestically and internationally, and are often used in conjunction with bone screws or bone wires in clinical practice.

[0003] Currently, common metal bone plates have fixed dimensions, which not only narrows their applicability but also makes it inconvenient to install bone screws. For example, CN 212466141 U discloses a locking type metal bone plate for orthopedics, which includes a bone plate with a first bone graft window on one side of the middle of the surface and a second bone graft window on the other side of the middle of the surface. Multiple screw mounting holes are provided on both sides of the surface of the bone plate. Cam positioning holes are provided on the side of the surface of the bone plate located at the screw mounting holes, and the screw mounting holes and cam positioning holes are connected. A positioning cam is rotatably connected in the cam positioning hole.

[0004] As can be seen from the above-disclosed scheme, the size of the metal bone plate is fixed, and its length and width cannot be adjusted according to actual needs, which reduces the scope of application. Furthermore, due to the fixed size, the wound size at the bone plate entry and exit point is large, and it is not easy to see the position of the fixed hole when installing screws. Moreover, it is necessary to limit the screws by using a positioning cam, which brings certain inconvenience to the user. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an orthopedic metal bone plate. This orthopedic metal bone plate, through the setting of a movable plate, a sleeve plate, a first adjusting rod, and a second adjusting rod, allows the length and width of the metal bone plate to be adjusted. This not only increases the applicability but also reduces the size of the wound at the bone setting site during use. Furthermore, the setting of strip holes, countersunk grooves, and locking grooves not only makes it easy for bone screws to see the positioning hole position but also allows for direct locking of bone screws, preventing slippage between the screws and the metal bone plate and improving ease of use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An orthopedic metal bone plate includes a metal bone plate body, which comprises a fixed component and a movable component. The fixed component and the movable component are movably connected and fastened together by a second adjusting screw. The fixed component includes symmetrical sleeve plates, and a first adjusting rod is movably connected between the symmetrical sleeve plates. The movable component includes symmetrical movable plates, and a second adjusting rod is movably connected between the symmetrical movable plates. This orthopedic metal bone plate, through the movable plates, sleeve plates, first adjusting rod, and second adjusting rod, allows for adjustment of its length and width, increasing its applicability and reducing the size of the incision at the bone setting site. Furthermore, the inclusion of a strip-shaped hole, countersunk groove, and locking groove facilitates easy viewing of the fixing hole position for the bone screw and allows for direct locking of the bone screw, preventing slippage between the screw and the metal bone plate and improving ease of use.

[0008] Furthermore, the end face of the socket plate is provided with a length adjustment groove, the inner wall of the length adjustment groove is slidably connected to the surface of the movable plate, the surface of the movable plate is provided with a connecting hole, one end of the connecting hole is connected to a second countersunk hole, the inner wall of the second countersunk hole is movably connected to the surface of the second adjusting screw, and the length adjustment groove allows the movable components at both ends of the socket plate to extend and retract, thereby adjusting the length of the metal bone plate.

[0009] Furthermore, the side of the socket plate has a width adjustment groove, the inner wall of the width adjustment groove is slidably connected to the surface of the first adjustment rod, the surface of the first adjustment rod has a first adjustment hole, and the surface of the first adjustment hole is threaded with a first adjustment screw. The width adjustment groove allows the two ends of the first adjustment rod to extend and retract, thereby adjusting the width between the two socket plates.

[0010] Furthermore, the movable plate has a side hole on its side, and the inner wall of the side hole is slidably connected to the surface of the second adjusting rod. The surface of the second adjusting rod has a second adjusting hole, and the inner wall of the second adjusting hole is threaded with a third adjusting screw. The side hole allows the two ends of the second adjusting rod to extend and retract, thereby adjusting the width of the two movable plates.

[0011] Furthermore, the surface of the movable plate has a countersunk groove, the inner wall of the countersunk groove has a strip-shaped hole, and the inner wall of the countersunk groove has locking grooves that are evenly distributed. The strip-shaped hole makes it easy for the user to see the fixed hole position of the bone screw, and the locking groove can limit one end of the bone screw.

[0012] Furthermore, one end of the movable plate has a T-shaped cross-section, and the length adjustment groove also has a T-shaped cross-section, so that the movable plate can only move in the length direction.

[0013] Furthermore, both the socket plate and the movable plate have first countersunk holes on their surfaces, which can prevent one end of the first adjusting screw and the third adjusting screw from protruding.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution, through the setting of movable plate, socket plate, first adjustment rod and second adjustment rod, enables the metal bone plate to adjust its length and width, which not only increases the scope of application, but also reduces the size of the wound at the bone setting site during use.

[0016] (2) The design of this solution, through the strip hole, countersunk groove and locking groove, not only makes it easy for the bone screw to see the fixed hole position, but also allows the bone screw to be locked directly, avoiding sliding between it and the metal bone plate, thus improving the ease of use.

The inner wall of the second countersunk hole 27 is movably connected to the surface of the second adjusting screw 29. The length adjusting groove 23 allows the sleeve plate 21 to be threadedly fastened to the surface of the movable plate 31. The movable components 3 at both ends of 1 can extend and retract to adjust the length of the metal bone plate. The socket plate 21, the first adjusting rod 24, the movable plate 31 and the second adjusting rod 36 are all medical bone plates. The first adjusting rod 24 is movably connected between the symmetrical socket plates 21. The movable component 3 includes symmetrical movable plates 31. The surface of the movable plate 31 has a countersunk groove 32. The inner wall of the countersunk groove 32 has a strip hole 34. The inner wall of the countersunk groove 32 has equidistantly distributed locking grooves 33. The strip hole 34 makes it easy for the user to see the fixed hole position of the bone screw. The locking groove 33 can limit one end of the bone screw. The second adjusting rod 36 is movably connected between the symmetrical movable plates 31.

[0027] The side of the socket plate 21 has a width adjustment groove 22. The inner wall of the width adjustment groove 22 is slidably connected to the surface of the first adjustment rod 24. The surface of the first adjustment rod 24 has a first adjustment hole 25. The surface of the first adjustment hole 25 is threaded with a first adjustment screw 28.
