Provided in the present invention is a bispecific antibody which comprises an anti-MUC1 VHH antibody fragment and an anti-CD16 VHH antibody fragment. The antibody fragment used in the present invention is a variable region sequence derived from a heavy chain camelid antibody and has a high binding affinity to the antigen. Antibody fragments recognizing MUC1 and CD16 are constructed in the same antibody molecule by the invention, so that the antibody molecule can specifically bind to MUC1 and CD16 molecules to promote the killing effect of NK cells on MUC1-positive expression cells and has an inhibiting effect on the growth of MUC1-positive tumors. Also provided is a conjugate of the bispecific antibodies, a related pharmaceutical composition and use.

A NiTi alloy root canal file with a flexibility gradient includes a tip segment (F), a middle segment (F) and a root segment (F) divided along the axis of the NiTi alloy root canal file with the flexibility gradient. The internal microstructure of the tip segment (F) of the root canal file is martensite M-phase, the internal microstructure of the middle segment (F) is R-phase, and the internal microstructure of the root segment (F) is austenite A-Phase. The present invention further provides a manufacturing method for the NiTi alloy root canal file with the flexibility gradient. The beneficial effect of the present invention is effectively improving safety in use.

NiTi alloy root canal file with flexibility gradient

A NiTi alloy root canal file with a flexibility gradient, having a tip, middle portion and rear portion divided along the longitudinal direction. The internal microstructure of the tip is martensite, of the rear portion is austenite, and of the middle portion is a combination of martensite and austenite. The microstructure of martensite is continuously reduced and the microstructure of austenite is continuously increased as the distance from the tip increases. A manufacturing method for the NiTi alloy root canal file with a flexibility gradient. As the internal microstructure of the NiTi alloy root canal file with a flexibility gradient gradually changes along the axial direction and the strength also gradually changes, the flexibility and strength show a gradient change along the axial direction of the root canal file, providing excellent cutting property, high anti-fatigue life and significantly improving operation performance, safety, and life of the root canal files.
