The invention discloses a staple
cartridge device (1). In an initial state, a blade (1033) of a
cutting knife (103) is arranged in a knife groove (1024); when the
cutting knife
propeller (106) moves forwards, the rack (1062) is meshed with the gear (1032) to drive the
cutting knife (103) to rotate, so that the blade (1033) is exposed; and when the cutter (103) is reset backwards, the cutter (103) is driven to rotate, so that the blade (1033) is retracted into the cutter groove (1024). According to the scheme, the nail bin device can carry the cutting knife, the cutting knife is hidden in the knife groove in the initial state, the cutting knife is opened through the structure transmission blade in the working process, and after tissue is
cut, the cutting knife is hidden in the knife groove through the structure transmission blade again. Compared with an existing
endoscope anastomat on the market, the
endoscope anastomat has obvious technical advantages and use hand feeling, and in the operation process, when tissue is
cut and sutured for multiple times, the nail bin with the cutting knife is replaced, and the performance is more stable.
