The invention relates to a wrapper prepuce circumcising device. As people have higher requirements on the body health and living quality, at present a laser or a mechanical direct cutting method is conventionally adopted for circumcising the wrapperprepuce, but by adopting the laser or the mechanical direct cutting method, the wrapper prepuce incision is unsmooth and incomplete, the amount of bleeding is also large, the surgical operation time is long, and difficulty in recovery after the surgical operation exists; and therefore, a wrapper prepuce circumcising device appears on the market, excessive rebundant wrapper prepuce can be circumcised in one step by the wrapper prepuce circumcising device, the amount of bleeding is less, the wrapper prepuce incision can be sewed in one step by utilizing a sewing staple, but the existing sewing staple on the wrapper prepuce circumcising device has problems that the working direction is instable, and the sewing staple is easily to wrapped by the recovery tissues after the surgical operation and difficult to drop off and remove. A novel staple cartridge structure is adopted and can store the sewing staple with wider cross section. Since a staple bridge of the sewing staple is large in area, when the sewing staple is jacked to move forwards to pass through, the stress is uniform, the direction is stable, accuracy in positioning is realized, an effect for preventing the wrapping of the tissues can be realized, and the staple can be automatically dropped off after the surgical operation.
