The invention discloses medical
forceps constructed based on multi-material 3D printing and a preparation method of the medical
forceps. Comprising the following steps: based on medical image data of a patient or a standard instrument model, carrying out personalized design through
computer aided design software, and constructing an integrated three-dimensional digital model; then
topological optimization is carried out, a weight reduction structure is designed in a non-key stress area, and
slicing software is used for
processing and generating a multi-material printing instruction file; then, multi-material 3D printing equipment is adopted, according to a preset
material distribution scheme, materials with different mechanical properties are used for synchronously and integrally printing in the areas of the clamp beaks, the movable joints and the clamp handles, and a clamp
green body is manufactured; and finally, carrying out cleaning, key part
surface finish machining and sterilization treatment to obtain a final product. Matched
forceps can be rapidly designed and manufactured according to special operation requirements, multiple materials with different properties are integrated on the same instrument, and the operation precision and effect are improved.
