Digitization bone fracture plate and manufacturing method thereof

Abstract

The invention discloses a digitization bone fracture plate and a manufacturing method thereof. The bone fracture plate comprises a body, wherein the body comprises a supporting section and connecting sections extended from each end part of the supporting section; screw holes are arranged on the connecting sections; the thickness of the connecting sections is smaller than that of the supporting section; and the top surface of the body transits smoothly from the supporting section to the connecting sections. The manufacturing method comprises: a, data acquisition: acquiring digital imageology materials of bones; b, modeling: setting up a three-dimensional module of the bone fracture plate, thus profile data of the three-dimensional module of the bone fracture plate is obtained; c, command conversion: designing a processing command of a digital control processing device; and d, bone fracture plate molding: preparing the bone fracture plate by utilizing a rapid molding technology according to the processing command by the digital control processing device. The invention has the advantages that because the supporting section attached to the fracture breaking end comprises no screw holes, the supporting section has not damaged structure, can bear force well, and is not easy to bend and crack; because the thickness of the supporting section is reduced, the volume occupied in the bodyby the bone fracture plate is reduced, and the stimulation to the surrounding muscle and soft tissue is reduced; and the manufacturing method of the bone fracture plate can be used to ensure the smooth manufacturing of the bone fracture plate.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to a digital bone plate and a preparation method thereof. Background technique [0002] Bone plate is currently the most commonly used internal fixation device for fracture treatment at home and abroad. So far, the use of bone plate to treat fractures has a history of more than 100 years. The treatment principle is to make an incision at the broken end of the fracture, place the bone plate so that the bone plate spans the fracture site, and use screws to fix the bone plate at both ends of the fracture. The bone at the broken end of the fracture is effectively fixed. Therefore, the structure of the bone plate all includes a strip-shaped or arched bone plate body similar in shape to the bone surface, and screw holes for passing screws are opened on the body. [0003] However, most of the existing bone plates are provided with a plurality of screw holes at interva...

AI Technical Summary

Problems solved by technology

Although the bone plate with the above structure enhances the structural strength of the body at the position of the screw hole, it increases the thickness of the bone plate at the elongated protrusion, resulting in an increase in the volume occupied by the bone plate, which easily leads to increased tension in the surrounding tissue and skin. It is not conducive to wound closure; the lack of fit between the steel plate and the fracture site can also cause the steel plate to irritate the surrounding tissues and muscles and cause pain, which is not conducive to the movement of the affected bone and affects the recovery of bone function
