  • Publication number: 20240189075
    Abstract: A bone fixture with various moduli has an implant body. The implant body includes a first implanting segment adapted to be implanted into a cortical bone of a bone and a second implanting segment adapted to be implanted into a cancellous bone of the bone and located below the first implant segment. A first young's modulus of the first implanting segment is smaller than a second young's modulus of the second implanting segment. Because the first young's modulus of the first implanting segment adapted to be implanted in the cortical bone is smaller than the second young's modulus of the second implanting segment adapted to be implanted in the cancellous bone, forces applied to the bone fixture can be evenly distributed to avoid the stress concentration at the cortical bone of the bone.

  • Publication number: 20220125494
    Abstract: A connectable locking plate assembly comprises a locking plate unit, a connection unit, and a locking component. The locking plate unit comprises multiple interconnecting fixing parts. The connection unit comprises multiple interconnecting positioning parts, and at least one of the positioning parts has an assembly recess. One of the fixing parts is inserted into the assembly recess. The locking component is mounted through the screw connecting hole on the connection unit and is screwed into the screw setting hole of the locking plate unit. Therefore, the connectable locking plate assembly can be assembled into an appropriate structure by assembling the locking plate unit, the connection unit, and the locking component to meet the sizes and outer shapes of the bones at the fracture site. Therefore, the assembly can increase the fitting and fixing effect to the bones, and can enhance convenience during assembling.

  • Publication number: 20220008204
    Abstract: A human implant includes at least one osteoconductive scaffold and at least one main carrier. The at least one osteoconductive scaffold is made of a metal material, is manufactured by 3D printing, and has at least one connecting portion, at least one separation element, and a proliferation portion. The at least one connecting portion is porous. The at least one separation element is disposed on one of two sides of the at least one connecting portion. The proliferation portion is disposed on one of two sides of the at least one separation element away from the at least one connecting portion, wherein osteoblasts proliferate in the proliferation portion. The at least one main carrier is made of a medical macromolecular material and is mounted to the at least one connecting portion being porous, such that the at least one main carrier is mounted to the at least one osteoconductive scaffold.

  • Publication number: 20210213684
    Abstract: A construction method for customization of modular bone plates based on additive manufacturing relies on a modularization technique to construct and save a plurality of bone plate modules in a database connected with an analysis unit through which collected images for patients' fractures or osteomiosis are simulated for recognizing an injury part and extent and estimating and displaying bone plates required on a specific area and/or extent. Some analyzed results of the analysis unit are read from an operation interface on which a user determines and selects the bone plate modules for a surgery operation; the files for the bone plate modules are transmitted to a remote manufacturing center through a processing unit and to an additive manufacturing apparatus from the manufacturing center for manufacture and output of finished bone plates with curved surfaces according to an additive manufacturing technology.

  • Patent number: 9728795
    Abstract: A complex fuel cell stack with hydrogen storage unit is introduced. Through the new configuration of the PEM fuel cell stack, no cooling system and cooling fluid is needed for the fuel cell stack, since hydrogen storage vessel can act as a heat sink to protect the expensive catalyst layer of the MEA of the fuel cell away from over-heated and damaged. In addition, the waste heat generated from the operation of the fuel cells can aid in release of hydrogen from hydrogen storage alloys inside the hydrogen storage vessel.
