Abstract

The application provides a slow-rebound safety surgical scissors, which comprises a first handle, a second handle, a driving shear head and a driven shear head, a connecting cavity is formed at the head of the first handle, the tail end of the driving shear head is rotationally connected in the connecting cavity through a rotating seat, a locking block is fixed in the connecting cavity, and a locking groove is formed at the tail end of the driving shear head and matched with the locking block; the tail end of the driving shear head is further fixed with a first rotating shaft seat, the connecting cavity is further fixed with a second rotating shaft seat, and a main adjusting cylinder is movably connected between the first rotating shaft seat and the second rotating shaft seat. The connecting cavity is formed at the head of the first handle, the tail end of the driving shear head is rotationally connected in the connecting cavity through the rotating seat, namely, the driving shear head can rotate in the connecting cavity, so that the driving shear head can be retracted to avoid unnecessary shearing effect caused by the blade when a large swing occurs during the transfer process, and the safety of the surgical scissors during use is improved.
