摘要:
Provided are a single-handed-operation surgical instrument and operation method thereof, the surgical instrument comprising an actuator (300), an intermediate connector (200), and a controller (100). The actuator (300), the intermediate connector (200) and the controller (100) are connected to one another in sequence. The actuator (300) comprises a staple cartridge component (3002), a staple anvil component (3001), and a driving component (3003). The controller (100) comprises a firing trigger mechanism, a firing safety mechanism, and an automatic reset mechanism. The surgical instrument has an automatic-reset function: if the firing safety mechanism is locked, the actuator (300) of the surgical instrument grasps a tissue when a doctor operates a firing trigger (111) when the doctor releases the firing trigger (111), the actuator (300) of the surgical instrument automatically resets and releases the grasped tissue. Such a function of the surgical instrument enables the doctor to single-handedly adjust a position where a stapler grasps the tissue, and further facilitates enhanced thickness uniformity of the grasped tissue by the doctor repeatedly grasping the same part of the tissue, thereby improving stapling and cutting effects.Font lobjet de cette invention un instrument chirurgical susceptible dêtre utilisé avec une seule main et son procédé de fonctionnement. Ledit instrument chirurgical comprend un appareil dexécution (300), un corps de connexion intermédiaire (200) et une commande (100), lappareil dexécution (300), le corps de connexion intermédiaire (200) et la commande (100) étant successivement connectés. Lappareil dexécution (300) comprend un ensemble cartouche dagrafe (3002), un ensemble enclume dagrafe (3001) et un ensemble dentraînement (3003). La commande (100) comprend, quant à elle, un mécanisme de déclenchement dallumage, un mécanisme de prévention dallumage et un mécanisme de remise à zéro automatique.
