Abstract
The present disclosure provides a circular stapler including an instrument body, a handle assembly and a staple pushing rod; wherein an indicator and a strike part are disposed in the instrument body, and the indicator is rotatably connected to the instrument body; when the stapler is in an initial state, the indicator is in a first position area and pressed against the strike part; when the stapler is in a firing state, the indicator is moved to a second position area and separated from the strike part; when the stapler being fired, the indicator returns to the first position area from the second position area, strikes the strike part and emits a strike sound. The strike sound prompts an operator that firing has been successfully completed, so that the operator can know the firing state of the stapler in time and user experience of the operator can be improved.
