Abstract
Abstract A suturing needle 1 with a suture 7, for surgical operations. The suturing needle is formed of a single tube 1a or two or more coaxial tubes, and a core 6 therein; the core 6 is fixed to the tip 2 and rear 5 of the suturing needle 1, whereby, if the suturing needle 1 is broken, broken pieces are not scattered and extraction of each broken piece from body tissue is facilitated. The suture 7 is fixed in a hole in the rear end of the needle 1.
