Fracture repair surgery is the most common orthopedic treatment surgery, and bone plates and screws are usually used to connect the fracture sites. In traditional fracture surgery, bone plates are usually straight long strips, but because the shapes of different parts of the human skeleton are different, the bone plates need to be bent according to needs to fit the bone surface, thereby achieving the ideal surgical requirements. The traditional bone plate bending wrenches or bone plate bending pliers on the market are generally single in function and inconvenient to operate, and require high professional ability of doctors, which greatly limits the timeliness, safety and reliability of fracture repair surgery.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0018] Combine Figure 1 A handheld multifunctional bone plate bending pliers comprises a left pliers head 1, a right pliers head 2 is arranged above the left pliers head 1, and a left pliers handle 11 and a right pliers handle 12 are respectively movably arranged on one side of the left pliers head 1 and the right pliers head 2, the left pliers head 1 and the right pliers head 2 are symmetrically arranged, and one side of the left pliers head 1 and the right pliers head 2 is rotatably connected with a second pin shaft 6, the second pin shaft 6 is fixedly connected with a second pin 5, and one end of the second pin 5 is arranged through the inside of the second pin shaft 6, the left pliers handle 11 and the right pliers handle 12 are symmetrically arranged, and one side of the left pliers handle 11 and the right pliers handle 12 is rotatably connected with a first pin shaft 9, the first pin shaft 9 is fixedly connected with a first pin 8, and one end of the first pin 8 is arranged through the inside of the first pin shaft 9.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Combine Figure 2-Figure 3 , one side of the left pliers handle 11 and the right pliers handle 12 are fixedly connected with a stop block A15, and the two groups of the stop blocks A15 are symmetrically arranged. The first pin 8 corresponds to the middle position between the two groups of the stop blocks A15. When in use, according to the size of the bone plate body 14 that needs to be lateral bent, it is inserted into the slot formed by the stop block A15 and the first pin 8, covering a wide range of lateral bending sizes. After the bone plate is inserted into the slot, hold the left pliers handle 11 and the right pliers handle 12 with one hand or both hands to apply pressure, and the side bending of the bone plate can be achieved through the double joint principle.

[0021] A short handle 13 is fixedly connected to the side of the left pliers handle 11 and the right pliers handle 12 away from each other. The short handle 13 makes it easier to hold the left pliers handle 11 and the right pliers handle 12 and apply pressure, thereby improving the grip comfort.

[0022] A handle spring 10 is fixedly connected between the left handle 11 and the right handle 12 . The arrangement of the handle spring 10 facilitates the left handle 11 and the right handle 12 to be reset.

[0023] The left pliers head 1 and the right pliers head 2 are fixedly connected to a stop block B16 on one side near the second pin 5. The second pin 5 and the first pin 8 are on the same horizontal line and the stop blocks B16 are symmetrically arranged on both sides of the second pin 5. When in use, according to the size of the bone plate body 14 that needs to be bent sideways, it is inserted into the slot formed by the stop block B16 and the second pin 5. After the bone plate is inserted into the slot, the left pliers handle 11 and the right pliers handle 12 are held with one hand or both hands to apply pressure to achieve the side bending of the bone plate.

[0024] A jaw pin 4 is fixedly connected to one side of the right pliers head 2, and a movable jaw 3 is rotatably connected to the outer side of the jaw pin 4. The movable jaw 3 is arranged inside the right pliers head 2, and a slot adapted to the movable jaw 3 is provided on the upper surface of the left pliers head 1. When in use, the bone plate main body 14 is placed between the left pliers head 1 and the right pliers head 2. The movable jaw 3 can rotate freely through the jaw pin 4, and can be pressed parallel to the curved surface of the bone plate in real time when bending, ensuring that the transverse surface of the bone plate is bent without deformation.

[0025] The right pliers head 2 and one side of the right pliers handle 12, as well as the left pliers head 1 and one side of the left pliers handle 11 are rotatably connected with an axis pin 7. Through the setting of the axis pin 7, the bone plate bending pliers are connected front and back, so that by pressing the left pliers handle 11 and the right pliers handle 12, the block A15 can be used to cooperate with the first pin shaft 9 to bend, and the second pin 5 and the second pin shaft 6 can be used to drive the left pliers head 1 and the right pliers head 2 to open and close, thereby completing the bending operation.

[0026] Specifically, through the setting of the block A15 and the first pin 9, when in use, the size of the bone plate that needs to be bent is inserted into the slot formed by the block A15 and the first pin 9, covering a wide range of lateral bending sizes. After the bone plate is inserted into the slot, the left clamp handle 11 and the right clamp handle 12 are held with one hand or both hands to apply pressure. Through the double-joint principle, the side bending of the bone plate can be achieved, integrating the transverse bending and side bending of the bone plate into one. The bone plate bending pliers have a wide range of bendable sizes, adapt to most bone plate bending, a more labor-saving double-joint structure, and a clamp handle that is comfortable to hold. At the same time, it simplifies the bone plate bending steps, and ultimately achieves the purpose of increasing the lateral bending size and facilitating operation.
