3D printing operation guide plate

Abstract

The invention relates to a 3D printing operation guide plate for sport injury treatment, which is manufactured by utilizing a 3D printing technique. The 3D printing operation guide plate comprises assemblies A (1) and B (7), wherein the assembly A (1) is divided into an upper part and a lower part, the upper part is a guide pipe (3), the lower part of the assembly A (1) is a shell (4) clung to the surface of a talus (5), the shell (4) extends from the side face of the talus (5) to the bottom surface of the talus (5) and the neck of the talus (5), the assembly A (1) is provided with a marking hole (6) between the guide pipe (3) and the shell (4), the assembly B (7) is a guide pipe adapting to a bone hole manufactured after cleaning lesion with a trephine (2), the length of the assembly B (7) is equal to the depth of a bone hole to be drilled by the trephine (2), guide holes (9) are formed around the assembly B (7), a wedge-shaped locating gap (8) is formed in the upper edge of the assembly B (7), and the position of the wedge-shaped locating gap (8) is coincident with the position of the marking hole (6) of the assembly A (1). The 3D printing operation guide plate provided by the invention achieves individual treatment, remarkably improves the accuracy of location, relieves the pain of patients, and is suitable for popularization and use in the sport injury treatment.

Description

technical field [0001] The invention relates to a surgical guide plate used for 3D printing sports injury treatment and a preparation method thereof. Background technique [0002] 3D printing technology began to appear in the mid-1980s. It is a technology based on digital simulation files and using adhesive powder materials to accumulate layer by layer to manufacture three-body entities. It has a wide range of applications, involving jewelry, footwear , architecture, automobiles, aerospace, medicine, guns, etc. The current application of 3D printing technology in medicine includes fused deposition modeling technology, selective laser sintering technology, in vitro printing technology, multi-nozzle molding technology, etc. [0003] In order to ensure the accuracy of positioning during the operation, reduce the risk of surgery and improve the success rate of the operation, there are existing literatures that design and manufacture surgical guides through 3D printing technology...

AI Technical Summary

Problems solved by technology

The former is highly subjective, the operation accuracy is not high, and the cleaning is often insufficient; the latter takes a long time to locate, requires high equipment, and causes radiation to both the surgeon and the patient, and X-rays can only show the location of the cyst in two dimensions. Positioning is not accurate enough
