Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a double bone plate for supracondylar femoral fractures. Background Technique

[0002] A fracture refers to the interruption of the continuity of trabeculae. A fracture caused by trauma is called a traumatic fracture, and a fracture caused by a minor injury due to a lesion in the bone itself is called a pathological fracture.

[0003] In orthopedic surgery, supracondylar femoral fracture is a common type of injury. For the treatment of this kind of fracture, double bone plates are widely used because they can provide stable fixation and promote fracture healing. It is necessary to develop a double bone plate for supracondylar femoral fractures to treat supracondylar femoral fractures.

[0004] Chinese Patent Publication No.: CN211094614U discloses "A Double Bone Plate for Supracondylar Femoral Fractures". Its technical solution is: there are positioning grooves on the distal end faces of the lateral supracondylar femoral bone plate and the medial supracondylar femoral bone plate respectively. The width of the positioning groove matches the diameter of the traction pin. There are screw holes on the plate surface of the extended bone piece opposite to the supracondylar femoral fracture part. The extended bone piece is detachably connected to the distal ends of the lateral supracondylar femoral bone plate and the medial supracondylar femoral bone plate respectively. The fixing steel bands are respectively located on the upper and lower sides of the supracondylar femur. The two ends of the fixing steel band are respectively connected to the connecting screw holes of the lateral supracondylar femoral bone plate and the medial supracondylar femoral bone plate. This bone plate changes the traditional positioning after implanting the bone plate to first positioning with a traction pin and then implanting the bone plate to cooperate with it, realizing rapid and accurate positioning. The extended bone piece, the fixing steel band and the movable fixing piece solve the problem that the existing bone plate cannot effectively fix complex supracondylar femoral fractures.

[0008] Preferably, the double bone plate is fixedly connected with the fixing block, and the fixing block is slidably connected with the adjusting block.

[0009] Preferably, the sliding block matches the sliding groove.

[0010] Preferably, there are multiple groups of the double bone plates, and multiple groups of the double bone plates are symmetrically arranged at both ends of the adjusting block.

[0011] Preferably, there are multiple groups of the fixing screw holes, multiple groups of the fixing screw holes are equidistantly distributed on the surface of the double bone plate, and multiple groups of the fixing screw holes are connected to each other in pairs through the connecting groove.

[0023] Please refer to Figures 1-4 , a double bone plate for supracondylar femoral fracture, comprising a double bone plate 1, one end of the double bone plate 1 is connected with a fixed block 2, both sides of the fixed block 2 are provided with slide blocks 3, the outside of the slide blocks 3 is sleeved with an adjusting block 4, the adjusting block 4 is provided with a sliding groove 5 at the corresponding position of the slide block 3, one side of the fixed block 2 is connected with a spring 6, the surface of the double bone plate 1 is provided with a fixed screw hole 7, a connecting groove 8 is provided on one side of the fixed screw hole 7, the double bone plate 1 is provided with an auxiliary fixed screw hole 9 around the fixed screw hole 7, and a pressure relief groove 10 is provided at the lower end of the double bone plate 1.

[0024] Through the above technical solutions, by adjusting the positions of the symmetrically arranged double bone plates, it is convenient to be applicable to the treatment situations with different bone lengths, improving the practicability to a certain extent, making doctors more flexible in surgical operations, being able to make real-time adjustments according to the actual situation to achieve the best fixation effect. By sliding the double bone plate 1 at both ends of the adjusting block 4, it is convenient to adjust the distance between the double bone plates. By providing multiple groups of fixed screw holes 7 and auxiliary fixed screw holes 9, the double bone plate can be more firmly fixed at the fracture site, reducing the displacement and misalignment of the fracture ends. At the same time, the auxiliary fixed screw holes 9 can provide additional fixing points, further increasing the stability of the bone plate, with more flexible operation and improving the stability of the double bone plate to a certain extent.

[0025] Specifically, the double bone plate 1 is fixedly connected with the fixed block 2, and the fixed block 2 is slidably connected with the adjusting block 4.

[0026] Through the above technical solution, by arranging an adjusting block 4 at one end of the fixing block 2, it is convenient for the double bone plate 1 to be slidably connected to the adjusting block 4, facilitating the adjustment of the length. The spring 6 plays a certain limiting role on the fixing block 2, and both ends of the spring 6 are fixedly connected to the two groups of fixing blocks 2 respectively.

[0027] Specifically, the slider 3 matches the chute 5.

[0028] Through the above technical solution, the chute 5 plays a limiting role on the slider 3. By using the chute 5 in cooperation with the slider 3, it is convenient to adjust the length of the double bone plate.

[0029] Specifically, there are multiple groups of double bone plates 1, and multiple groups of double bone plates 1 are symmetrically arranged at both ends of the adjusting block 4.

[0030] Through the above technical solution, multiple groups of double bone plates are convenient for treating both ends of bone fractures, can be adjusted according to the different lengths of the patient's bones, and multiple groups of double bone plates 1 slide in the adjusting block 4 to achieve the adjustment function.

[0031] Specifically, there are multiple groups of fixing screw holes 7, and multiple groups of fixing screw holes 7 are equidistantly distributed on the surface of the double bone plate 1. Multiple groups of fixing screw holes 7 are connected to each other in pairs through the connecting grooves 8.

[0032] Through the above technical solution, multiple groups of fixing screw holes 7 facilitate doctors to select appropriate positions for fixation according to different fracture conditions. Multiple groups of connecting grooves 8 improve the adaptability and flexibility of the double bone plate, and are convenient for the bone plate to deform to a certain extent when subjected to external forces to adapt to bones of different shapes and sizes.

[0033] Specifically, there are multiple groups of auxiliary fixing screw holes 9, and multiple groups of auxiliary fixing screw holes 9 are equidistantly distributed around the fixing screw holes 7.

[0037] In use, when treating a fracture site, the doctor places the double bone plate 1 against the position where it needs to be installed according to the fracture condition, selects the positions for fixation in the fixing screw holes 7 and the auxiliary fixing screw holes 9 for fixation. After fixation, the other set of double bone plates 1 is moved. The movement of the double bone plates 1 drives the movement of the fixing blocks 2, and the movement of the fixing blocks 2 drives the sliders 3 to slide in the sliding grooves 5. At the same time, the springs 6 deform, and the other set of double bone plates 1 is moved to a suitable position for installation.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit, and the scope is defined by the appended claims and their equivalents.
