Problems solved by technology

[0002] The bone contact surface of the bone plate currently used clinically is a simple planar design or a limited contact surface, which brings the following technical problems: 1. The contact area with the bone is small, and the friction and holding force are small; 2. Due to different patients The bones are different, and there are certain differences in size. Even if a standard model of bone plate is selected, it is difficult to match it completely; therefore, it is often slightly bent to fit the bone wall, and the bone plate is often made of medical stainless steel and titanium. Made of alloy material, it has good recovery after elastic deformation. Therefore, the bone plate is not easy to shape, and there is a large stress concentration. The locked screw holes are prone to offset, causing loosening or fracture, which affects recovery.

Embodiment Construction

[0021] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0022] Such as Figure 1-Figure 4 A specific embodiment of a multi-tooth bone bone plate of the present invention is shown, which includes a plate body 1 , the bone contact surface of the plate body 1 is serrated, and the length direction of the tooth groove 101 is perpendicular to the length direction of the plate body 1 .

[0023] In this embodiment, the contact area with the bone is large, the friction force and the holding force of the multi-tooth structure are large, and the fixation strength is increased. In addition, since the bone contact surface is jagged, and the length direction of the alveolar 101 is perpendicular to the length direction of the pl...

Abstract

The invention belongs to the technical field of medical instruments, in particular to a multi-tooth bonesetting plate. The multi-tooth bonesetting plate comprises a plate body. A bone contact surfaceof the plate body is jagged. Additionally, the length direction of each tooth groove is vertical to the length direction of the plate body. The multi-tooth bonesetting plate has the following beneficial effects: the area of contact between the plate and a bone is large; friction force and holding force of a multi-tooth structure are great so that fixation strength is increased; due to the fact that the bone contact surface is jagged and the length direction of each tooth groove is vertical to the length direction of the plate body, the plate is likely to bend, difficult to restore and easy toshape during bone-type matching; stress concentration is reduced; and all locked screw holes are not likely to deviate and deform and does not loosen or break, which is good for recovery of a patient.
