Abstract

The invention discloses a surgical stitching instrument with an automatic restoration safety device. The surgical stitching instrument comprises a housing, a percussion handle rotating relative to the housing, a base arranged in the housing and provided with an inner cavity, a safety block in axial and rotary connection with the housing through a first rotary shaft, and a limiting component located in the inner cavity of the base. The safety block is provided with a first end, a second end and a restoration end. A protrusion is arranged on the percussion handle, and the first end makes contact with the limiting component. When the safety block makes axial rotation in the housing and the first end is clamped to a first limiting position formed between the limiting component and the base, the protrusion abuts against the second end; when the first end is clamped to a second limiting position formed between the limiting component and the base, the protrusion disengages from the second end and abuts against the restoration end. The surgical stitching instrument can restore automatically after percussion. Besides, the surgical stitching instrument is small in structure and high in safety performance, and has a clear voice prompt function.
