SURGICAL SYSTEM AND METHOD OF CONTROLLING SURGICAL SYSTEM

A surgical system according to an embodiment may include a patient-side apparatus, an operator-side apparatus including an operation part to receive an operation for operating a surgical instrument attached to an arm of the patient-side apparatus, and a controller configured to control an operation of the surgical instrument based on the operation received by the operation part. The controller is configured to: control rotation amounts of first and second drive parts to drive first and second elongate elements for opening and closing first and second jaw members of the surgical instrument such that an opening angle between the first and second jaw members correspond to an operating angle received by the operation part; and correct, according to a rotation angle of a shaft of the surgical instrument about a rotation axis of the shaft, the rotation amounts of the first and second drive parts that correspond to the operating angle.

Multi-fire lead screw stapling device

A surgical stapling device comprises a housing and a plurality of cartridges that are coupled together to form a barrel that is rotatably supported within the housing. Each of the cartridges defines a plurality of staple pockets that support a plurality of staples. An anvil is pivotally coupled to the housing and is movable in relation to the barrel between an open position and a clamped position. A drive shaft extends through the housing and through the barrel and a pusher operatively connected to the drive shaft. The pusher is configured to translate through the barrel to eject the staples from the plurality of cartridges in response to actuation of the drive shaft. The barrel is positioned within the housing to align a first one of the plurality of cartridges with the anvil to eject the staples from the first cartridge upon movement of the pusher within the barrel through a first firing stroke and subsequently rotatable within the housing to align a second one of the plurality of cartridges with the anvil to eject the staples from the second cartridge upon movement of the pusher within the barrel through a second firing stroke.
