Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a biomechanically reinforced steel plate. Background Art

[0002] Fractures are common and frequently occurring orthopedic diseases. Once a fracture occurs, it will lead to varying degrees of loss of working ability in patients, and in severe cases, it may even lead to death or disability. The ultimate goal of treating fractures is to restore the function of the injured limb to the maximum extent possible. Therefore, in the surgical treatment of fractures, reduction and fixation are very important. Studies have shown that in the process of fracture recovery, pressure perpendicular to the fracture line is conducive to fracture healing, while shear force parallel to the fracture line can easily lead to dislocation of the broken ends, which can lead to delayed healing or even nonunion. Current plate fixation mainly uses steel plates to firmly fix the fracture site. However, after firm fixation, although the shear force parallel to the fracture line that hinders healing is reduced, the pressure perpendicular to the fracture line that promotes healing is also greatly reduced. Currently, there is no steel plate that can simultaneously achieve the function of reducing shear force while maintaining pressure perpendicular to the fracture line. Summary of the Invention

[0003] The present invention aims to provide a biomechanically enhanced steel plate to solve the problems of the prior art orthopedic fixation steel plates, such as single structure, poor mechanical properties and poor adaptability.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A biomechanical enhancement steel plate includes a steel plate body, which is a "concave" plate. The steel plate body is provided with an arc-shaped through hole, a circular hole and a transverse adjustment hole. The arc-shaped through hole passes through the two vertical side walls of the steel plate body, and the circular hole and the transverse adjustment hole pass through the upper side wall of the steel plate body. There are multiple circular holes and transverse adjustment holes, and the multiple circular holes and transverse adjustment holes are intermittently arranged. The steel plate body includes a front end and a rear end, and the front end gradually narrows along one side of the rear end. The front end is provided with an interruption groove, and the rear end is provided with an interruption protrusion. The interruption protrusion and the interruption groove are arranged in coordination, and the interruption protrusion and the interruption groove are simultaneously connected to the arc-shaped through hole.

[0006] Furthermore, the interruption groove is in a wedge shape that is larger on the outside and smaller on the inside, and the interruption protrusion is in a wedge shape that is smaller on the outside and larger on the inside.

[0007] Furthermore, a vertical adjustment hole is provided on the upper side wall of the steel plate body, and the vertical adjustment hole is provided on one side of the front end.

[0008] Furthermore, the diameter of the circular hole is 5 mm, the width of the vertical adjustment hole and the horizontal adjustment hole is 5 mm, and the adjustment range of the vertical adjustment hole and the horizontal adjustment hole is 10 to 20 mm.

[0009] Furthermore, the two vertical side walls of the steel plate body are penetrated by a curved through hole, the curved through hole is arranged on one side of the rear end, the curved through hole is arc-shaped, and a curved protrusion is provided in the middle of the curved through hole, and the curved protrusion is also arc-shaped.

[0010] Furthermore, the curvature diameter of the arc-shaped through hole is 200 mm, the length of the arc-shaped through hole is 40 mm, the arc-shaped through hole is located at 1 / 3 of the steel plate body, the curvature diameter of the bent through hole is 120 mm, the length of the bent through hole is 10 mm, and the bent through hole is located at 4 / 5 of the steel plate body.

[0011] The principle and beneficial effects of this technical solution are:

[0012] 1. The steel plate body is "concave" shaped, and its two side walls in the vertical direction are equivalent to the ribs of the steel plate body, and its mechanical properties are good. The intermittent circular holes and transverse adjustment holes on the steel plate body can be used to select the fixed position according to the patient's fracture situation, which has a good fixation effect on the steel plate. The vertical side walls of the steel plate body are provided with arc-shaped through holes, and the interrupted grooves at the front end cooperate with the interrupted protrusions at the rear end. When the steel plate body is subjected to a bending force, the steel plate body can bend to a certain extent under the action of the arc-shaped through holes. At the same time, the interrupted protrusions and interrupted grooves abut against each other, which is further beneficial to the bending of the steel plate body and can avoid the harm to the patient caused by the sudden large-angle bending of the steel plate body. At the same time, it can also avoid the relative dislocation of the front end and the rear end, so that the patient's reinforced steel plate can not only effectively support the fracture site, but also flex and stretch appropriately to improve the patient's healing efficiency;

[0013] 2. The interruption groove is in the shape of a wedge with a large outside and a small inside, and the interruption protrusion is in the shape of a wedge with a small outside and a large inside. The two cooperate with each other to achieve automatic positioning and correction between the front and rear ends when the steel plate body bends and recovers, avoiding misalignment between the front and rear ends and achieving good adaptive effect.

[0014] 3. The buckling through holes opened on the two vertical side walls at the rear end of the steel plate body disperse the stress when the steel plate body is bent. The buckling protrusion abuts against the upper side wall of the buckling through hole to support it, further improving the mechanical properties of the reinforced steel plate.

[0015] 4. The side wall of the steel plate body is provided with arc-shaped through holes and buckling through holes, which can convert the stress during weight-bearing into elastic stress, acting on the fracture ends, forming micro-motion of the fracture ends within a range of 2mm, thereby promoting early fracture healing while ensuring the patient's early weight-bearing after surgery.
