SURGICAL ANASTOMAT

摘要

A surgical anastomat comprises a staple cartridge assembly (11), a staple anvil assembly (12), and an operation portion. The staple cartridge assembly (11) comprises a staple cartridge portion (111) provided with staple cartridges (1110), a staple pushing apparatus (112) capable of pushing out an anastomosing staple (1111) in the staple cartridges (1110), and a cutter (113) used for cutting a remaining tissue after the stapling. The operation portion is connected to the staple cartridge portion (111), and can control actions of the staple pushing apparatus (112) and the cutter (113). The operation portion is provided with a first butt joint (123) for butt junction. The staple anvil assembly (12) comprises a staple anvil portion (121) provided with staple anvils (1210), and a second butt joint (1221) capable of being connected to the first butt joint (123). The staple anvil portion (121) matches the staple cartridge portion (111), and the staple cartridges (1110) are corresponding to the staple anvils (1210) in a one-to-one manner. The staple cartridges (1110) are disposed on a side surface of the staple cartridge portion (111) and the staple anvils (1210) are disposed on a side surface of the staple anvil portion (121) to obtain the longitudinal anastomosing. The surgical anastomat longitudinally anastomoses an anastomosing organ or tissue, increases the anastomosing area, and narrowness is unlikely to occur on an anastomosed position.
