AI Technical Summary
When fixing the positioning screws, the existing straight plate type bone plates usually can only place the positioning screws of the corresponding size, and the inclination angle of the positioning screws cannot be adjusted, resulting in the need to replace the bone plate when replacing or adjusting the screws.
A new straight plate bone plate was designed, including an adjustment component and a moving component. The adjustment component realizes adaptation to the different sizes and inclination angles of the positioning screws through the cooperation of the slide chute, slider, movable plate and fixing bolt; the movable component reduces the contact area with the outside of the bone and adapts to the arc of the bone through the cooperation of the movable column, fixing disc and movable block.
The fixation of positioning screws of different sizes is achieved, and the inclination angle of the screws can be adjusted, avoiding frequent replacement of bone plates and improving the applicability and flexibility of bone plates. At the same time, through the design of the moving components, local compression on the bones is reduced and the patient's comfort is improved.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a novel straight bone plate. Background Art
[0002] A straight bone plate is a medical device used for internal fixation of fractures. It is usually made of metal (such as stainless steel or titanium alloy) and is straight in shape. It is used to bridge and fix the two ends of a fracture. Positioning screws are usually placed through multiple arc holes.
[0003] When fixing the positioning screws, the existing straight bone plates can usually only place positioning screws of corresponding sizes. When the size of the positioning screws is changed, the straight bone plates also need to be replaced. At the same time, when fixing the positioning screws, the inclination angle of the positioning screws cannot be adjusted. Therefore, it is necessary to provide a straight bone plate that can fix positioning screws of different sizes and can adjust the inclination angle of the positioning screws to fix the positioning screws. Utility Model Content
[0004] The purpose of the utility model is to provide a novel straight plate bone plate to solve the problem in the above-mentioned background technology that when fixing the positioning screws, the existing straight plate bone plates can usually only place positioning screws of corresponding sizes. When the size of the positioning screws is changed, the straight plate bone plate also needs to be replaced. At the same time, when the positioning screws are fixed, the inclination angle of the positioning screws cannot be adjusted.

[0007] A bone plate assembly, the bone plate assembly comprising a bone plate body;
[0008] An adjustment component, the adjustment component comprising a slide groove, a slider, a movable plate, a second positioning hole, a fixing block, a first fixing hole, a second fixing hole and a fixing bolt;
[0009] The slide groove is opened at both sides of the bone plate body, the slider is slidably connected to the internal position of the slide groove, the movable plate is fixedly connected to the inner position of the slider, the second positioning hole is opened at the upper end of the movable plate, the fixed block is fixedly connected to the internal positions of the two ends of the bone plate body, the first fixing hole is opened at the internal position of the outer end of the movable plate, the second fixing hole is opened at the central position of the fixing block, and the fixing bolt is threadedly connected to the internal positions of the first fixing hole and the second fixing hole.
[0010] Furthermore, the bone plate assembly further comprises a first positioning hole;
[0011] The first positioning hole is opened at the upper end of the bone plate body.
[0012] Furthermore, the movable plate is located at two sides of the bone plate body, and the first positioning hole and the second positioning hole are corresponding structures.
[0013] Furthermore, the inner surfaces of the first fixing hole and the second fixing hole have threaded structures opened relative to the fixing bolts, and the fixing block is located at the outer side of the movable plate.
[0014] Furthermore, it also includes a movable component, which includes a first through hole, a second through hole, a movable column, a fixed disc, a movable block and a hollow groove;
[0015] The first through hole is opened at the upper end of the bone plate body, the second through hole is opened at the bottom end of the bone plate body, the movable column is threadedly connected to the inner position of the second through hole, the fixed disk is fixedly connected to the bottom end of the movable column, the movable block is sleeved on the outer surface of the fixed disk, and the hollow groove is opened at the inner position of the upper end of the movable block.

[0017] Compared with the prior art, the advantages of the present invention are:
[0018] 1. The utility model provides an adjustment component. When it is necessary to fix positioning screws of different sizes or to adjust the inclination angle of the positioning screw, the fixing nut is rotated inside the first fixing hole and the second fixing hole. The fixing nut drives the movable plate to move through the threaded structure. The movement of the movable plate drives the second positioning hole and the first positioning hole to intersect. While changing the overlapping area of the first positioning hole and the second positioning hole, the inclination angle of the positioning screw can be changed.
[0019] 2. Based on beneficial effect 1, a movable component is set up, and the movable column is rotated to make the movable column rotate inside the second through hole. The movable column is driven by the threaded structure to rotate and move up and down. The movable column drives the fixed disk to rotate and move up and down. The fixed disk rotates in the hollow groove and drives the movable block to move up and down. The movable block does not rotate when moving up and down. By bringing the movable block into contact with the outside of the bone and reducing the contact area with the bone, the movable block can apply the same force to the outside of the bone according to the curvature of the patient's bone, so that the patient will not be excessively compressed locally.
