Technical Field

[0001] The utility model relates to the technical field of bone plates, in particular to a bone plate structure with a curved surface structure. Background Art

[0002] A bone plate is a medical device used for fracture fixation. Its purpose is to maintain the stability of the fracture ends during the healing process and promote fracture healing. Bone plates are typically made of metals, such as stainless steel and titanium alloys, which have excellent biocompatibility and mechanical properties.

[0003] When existing bone plates are used, since the length of bones varies from person to person, bone plates of different lengths usually need to be customized when a fracture needs to be fixed. The customization and production of bone plates wastes a certain amount of time, making it impossible to fix the patient's fracture in a timely manner. Therefore, it is necessary to provide a bone plate that can be adjusted to different lengths to adapt to different bones to fix the fracture position. Utility Model Content

[0004] The purpose of the present utility model is to provide a bone plate structure with a curved surface structure to solve the problem raised in the above background technology that when the existing bone plates are used, due to the different lengths of bones of each person, when the fracture position needs to be fixed, bone plates of different lengths usually need to be customized, and a certain amount of time is wasted in the customization and production of the bone plates, which makes it impossible to fix the patient's fracture in time.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a bone plate structure with a curved surface structure, comprising:

[0007] Bone plate body;

[0008] A movable assembly, comprising an extension plate, a support block, a support shaft, a movable tube, a limit block, a first slide groove, and a second slide groove;

[0009] The extension plate is slidably connected to one end of the bone plate body, the support block is fixedly connected to both sides of one end of the extension plate, the support shaft is sleeved at the central position inside the support block, the movable tube is sleeved at the outer surface positions of both ends of the support shaft, the limit block is fixedly connected to the outer end position of the movable tube, the first slide groove is opened at both sides of the bone plate body, and the second slide groove is opened at the outer side of the first slide groove.

[0010] Furthermore, both ends of the support shaft extend outward through the support block, and corresponding thread structures are provided on the outer surfaces of both ends of the support shaft and the inner surface of the movable tube.

[0011] Furthermore, the movable tube is located inside the first chute, and the limit block is located inside the second chute.

[0015] Furthermore, the fixing column extends outward through both sides of the bone plate body, and an outer surface of the fixing column has a threaded structure opened relative to the fixing nut.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. The utility model provides a movable component. When the length of the bone plate body needs to be adjusted, the support shaft is rotated to make the movable tube move outward under the driving force of the limit block and the threaded structure, so that the movable tube and the limit block move outward without contacting the bone plate body. Then the extension plate is moved to the corresponding length, and the support shaft is rotated in the opposite direction to drive the movable tube and the limit block to move inward. When the outer ends of the movable tube and the limit block are in contact with the bone plate body respectively, the movable tube and the limit block are fixed inside the bone plate body, so that the extension plate is fixed inside the bone plate body by the support shaft, thereby achieving the effect of changing the length of the bone plate body.

[0018] 2. Based on the first beneficial effect, by setting an adjustment component, by rotating the fixing plate, the fixing plate drives the fixing block to rotate, the fixing block rotates along the fixing column, the fixing column rotates inside the placement slot, and then the fixing column is fixed by the fixing nut, so that the fixing column is fixed inside the placement slot, the fixing plate and the fixing block can be fixed inside the placement slot, and the angles of the fixing plate and the fixing block at the front end of the bone plate body can be changed to adapt to the arc conditions of different bone parts.

[0030] See also Figure 1-3 As shown, this embodiment is a bone plate structure with a curved surface structure, comprising:

[0031] Bone plate body 11;

[0032] The movable assembly includes an extension plate 21, a support block 22, a support shaft 23, a movable tube 24, a limit block 25, a first slide groove 26 and a second slide groove 27;

[0033] The extension plate 21 is slidably connected to one end of the bone plate body 11, the support block 22 is fixedly connected to both sides of one end of the extension plate 21, the support shaft 23 is sleeved at the center of the support block 22, the movable tube 24 is sleeved at the outer surfaces of both ends of the support shaft 23, the limit block 25 is fixedly connected to the outer end of the movable tube 24, the first slide groove 26 is provided at both sides of the bone plate body 11, and the second slide groove 27 is provided at the outer side of the first slide groove 26;

[0034] The extension plate 21 is used to extend the length of the bone plate body 11, the support block 22 is used to support the support shaft 23, the support shaft 23 is used to support the movable tube 24, the movable tube 24 is used to support the limit block 25, the limit block 25 is used to limit the movable tube 24, the first chute 26 is used to place the movable tube 24, and the second chute 27 is used to place the limit block 25;

[0035] Both ends of the support shaft 23 extend outward through the support block 22, and corresponding thread structures are formed on the outer surfaces of both ends of the support shaft 23 and the inner surface of the movable tube 24;

[0036] The support shaft 23 can rotate inside the support block 22;

[0037] The movable tube 24 is located inside the first chute 26 , and the limit block 25 is located inside the second chute 27 ;

[0038] When the movable tube 24 and the limiting block 25 are in contact with the bone plate body 11 respectively, the movable tube 24 and the limiting block 25 exert inward pressure on the bone plate body 11, thereby being fixed inside the first chute 26 and the second chute 27 respectively;

[0039] Both ends of the support shaft 23 are located inside the first sliding groove 26, and the bone plate body 11 is a curved structure;

[0040] When the support shaft 23 rotates, the movable tube 24 and the limit block 25 can be driven to move horizontally through the thread structure;

[0041] Working principle: When the length of the bone plate body 11 needs to be adjusted, a rotational force is applied to the support shaft 23, so that the support shaft 23 rotates inside the support block 22. The rotation of the support shaft 23 applies a rotational force to the movable tube 24 through the threaded structure. Since the outer side of the limit block 25 and the inside of the second slide groove 27 fit together, the limit block 25 limits the movable tube 24, so that the movable tube 24 does not rotate with the support shaft 23, and the movable tube 24 is driven outward by the threaded structure, so that the movable tube 24 and the limit block 25 move outward until they are separated from the bone plate body 11, and then the extension plate 21 is moved to the desired position, and a reverse rotational force is applied to the support shaft 23, so that the support shaft 23 drives the movable tube 24 and the limit block 25 to contact the bone plate body 11 and apply an inward force to the bone plate body 11, so that the extension plate 21 is fixed in the internal position of the bone plate body 11.

[0047] The fixing block 32 can rotate along the fixing column 34 and drive the fixing plate 33 to rotate;

[0048] Working principle: When the angle of the fixing plate 33 needs to be adjusted to adapt to bone parts with different curvatures, the fixing nut 35 is screwed outward so that the fixing nut 35 does not fix the fixing column 34, and then a rotational force is applied to the fixing column 34 so that the fixing column 34 drives the fixing block 32 and the fixing plate 33 to rotate. When the fixing plate 33 rotates to the desired position, the fixing nut 35 is screwed inward to fix the fixing column 34, so that the fixing block 32 and the fixing plate 33 are fixed inside the front end of the bone plate body 11.
