Description

Technical Field

[0001] This utility model relates to the field of medical devices, and more specifically, to a locking metal bone plate. Background Technology

[0002] The tibia is a long bone on the medial side of the lower leg, consisting of a body and two ends. The proximal end of the tibia is enlarged and protrudes laterally to form the medial malleolus and lateral condyle. The upper surfaces of the two condyles are smooth and form articular surfaces. The area between the two condyles is the intercondylar region, with the intercondylar eminence in the middle. On the anterior side of the proximal end of the tibia, there is a rough ridge called the tibial tuberosity, which is the attachment point of the patellar ligament. Behind the lateral condyle, there is a round fibular articular surface that articulates with the head of the fibula. The cross-section of the tibial body is triangular. Its anterior edge and the entire length of its anteromedial surface lie subcutaneously, making it the most prone site for fracture. During surgical treatment, a bone plate is required for auxiliary support.

[0003] The utility model patent with authorization announcement number CN 215937624 U discloses a lateral locking metal bone plate for proximal tibia repair using a suture-supported universal locking system, relating to the field of medical device technology. This utility model includes a bone plate, an operating head, and a tail end. The operating head is located at one end of the bone plate, and the tail end at the other end. One side surface of the operating head has locking screw holes and suture holes, with the suture holes located outside the locking screw holes. The other side surface of the operating head has a suture groove, with the suture holes and suture grooves corresponding to each other. The tail end has a beveled surface. A telescopic plate is connected to one end of the bone plate. Locking rods are installed on both opposite sides of the bone plate, adapting to the telescopic plate. Fixing bolts are installed on the surface of the locking rods. This utility model, based on the actual shape and injury state of the tibia, utilizes the telescopic plate to adjust the length and distance of the bone plate, and uses graduated lines for position adjustment, enhancing the fit between the bone plate and the tibia and improving the rehabilitation effect of the tibia.

[0004] In the above-disclosed structure, locking holes and suture holes are directly set on the surface of the bone plate. The lack of locking holes and connecting grooves for countersunk connections is not only unfavorable for the positioning and connection screws, which can easily cause excessive thickness increase and affect positioning, but also unfavorable for mutual drainage of multiple positions, resulting in poor adaptability. In addition, the lack of combination strips and combination slots makes it impossible to combine and connect with each other, which needs to be improved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a locking metal bone plate. By connecting the bone plate to the turning plate, an extruded structure can be formed, and countersunk holes are set on the surface to connect the locking hole and the connecting groove, thus forming a suitable connection structure. This facilitates the installation of screws for fixation, makes connection and drainage convenient, and has high adaptability. Furthermore, the side is provided with combination strips and combination slots, which can be inserted and positioned together to ensure safety and stability and facilitate adjustment and use.

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

[0007] A locking metal bone plate includes a bone plate, a turning plate fixedly connected to one end of the bone plate, an arc-shaped corner at the corner of the bone plate and the turning plate, countersunk holes on both sides of the bone plate and the turning plate, a locking hole in the middle of the countersunk hole, a connecting groove on the side of the countersunk hole located in the middle of the surfaces of the bone plate and the turning plate, suture holes on both sides of the turning plate, an opening slit on one side of the suture hole located at the edge of the turning plate, a combination slot on one side of the bone plate, and a combination strip fixedly connected to the other side of the bone plate, the combination strip being aligned with the thickness of the combination slot.

[0008] Furthermore, the lower surface of the bone plate is provided with an elongated limiting groove, which is located on both sides of the countersunk hole.

[0009] Furthermore, the upper surface of the bone plate is provided with a limiting groove, which is aligned with the two ends of the elongated limiting groove.

[0010] Furthermore, the limiting groove and the elongated limiting groove are located on both sides of the bone plate, and the positions of the two sides correspond to each other. By setting the elongated limiting groove and the limiting groove on the upper and lower sides of the bone plate, the positions can be marked with each other, which facilitates the alignment and installation, avoids misalignment, and different limiting structures can be selected for matching, which has high adaptability.

[0011] Furthermore, the bone plate and the transition plate are an integral structure and are perpendicularly connected to each other.

[0012] Furthermore, the countersunk holes are evenly distributed on the surfaces of the bone plate and the transition plate, and the depth of the connecting groove is half the depth of the countersunk holes.

[0013] Furthermore, the suture holes are evenly distributed on both sides of the turning plate, and the width of the opening slit is half the diameter of the suture hole. By evenly distributing the countersunk holes and suture holes, it is easy to arrange them evenly, facilitate combination, connection and positioning, and strengthen the suture line, thus achieving high adaptability.

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