A motorized surgical instrument is disclosed. The surgical instrument includes a displacement member, a motor coupled to the displacement member, a control circuit coupled to the motor, a position sensor coupled to the control circuit, and a timer circuit coupled to the control circuit. The timer circuit is configured to measure elapsed time and to to receive, from the position sensor, a position of the displacement member in a current zone during a set time interval, measure displacement of the displacement member at a set time at the end of the set time interval, wherein the measured displacement is defined as the distance traveled by the displacement member during the set time interval at a set command velocity for the current zone, and set a command velocity of the displacement member for a subsequent zone based on the measured displacement of the displacement member within the current zone.

A loading unit for use with a surgical instrument includes a body configured for coupling to a surgical instrument and defining a longitudinal axis and having proximal and distal ends, and an end effector coupled to the distal end of the body. The end effector includes a staple cartridge assembly having a staple cartridge and an anvil assembly having an anvil plate. A drive assembly is at least partially disposed within the body. The drive assembly includes an actuator member having a roller engageable with at least one of the staple cartridge assembly or the anvil assembly. The roller is configured to rotate upon longitudinal movement of the drive assembly to facilitate movement of the drive assembly and relative movement of the staple cartridge assembly and the anvil assembly between open and approximated conditions.

Locking assemblies for surgical clamping and cutting instruments include a locking member and a switch. A drive member may be configured to releasably engage a knife and/or a shuttle of the surgical instrument for translating the knife and/or shuttle in a distal direction through a firing stroke. The locking member is movable from a first position permitting distal translation of the drive member through the firing stroke, and a second position inhibiting distal translation of the drive member through the firing stroke. A switch, when proximally positioned, releasably engages the locking member to maintain the locking member in the first position. The switch disengages from the locking member when the switch is moved to a distal position.

Surgical stapling instruments are disclosed comprising a staple cartridge, a firing member, and a cartridge lockout configured to prevent the firing member from being advanced through the staple cartridge if the staple cartridge has been already spent. The stapling instruments further comprise a lockout in the shaft that responds to the cartridge lockout blocking the firing member.

A method, system, medium, and implementations for computer-aided preoperative surgical planning are described. Input data acquired with respect to a part of a patient is received by the system. The part corresponds to an organ, e.g., lung, of the patient to be operated on and includes one or more lesions to be removed during an operation. Then, an anatomic 3D model of the part of the patient is generated. Based on the generated anatomic 3D model, a preoperative plan for linear-cutting stapler resection of the one or more lesions from the organ to be carried out during the operation is obtained. The stapler cartridge size and the staple length are estimated based on the preoperative plan. Further, the resection based on the preoperative plan is visualized.

A computing system may identify a surgical instrument for a surgical procedure in an operating room (OR). The computing system may detect a control input by a health care professional (HCP) to control the surgical instrument. The computing system may determine the HCP's access control level associated with the surgical instrument. The computing system may determine whether the HCP has an authorization to control the surgical instrument. If the computing system determines that HCP is unauthorized to control the surgical instrument based on the access control level associated with the HCP, the computing system may block the control input by the HCP. If the computing system determines that the HCP is authorized to control the surgical instrument based on the access control level associated with the HCP, the computing system may effectuate the control input by the HCP to control the surgical instrument.

A surgical instrument comprising a first jaw, a moveable second jaw, and one or more mounting brackets that retain said second jaw to said first jaw is disclosed.

A surgical stapling apparatus includes a cartridge assembly defining a tissue contacting surface; an anvil assembly defining a tissue contacting surface; and a surgical buttress releasably secured to at least one of the tissue contacting surface of the cartridge assembly and the tissue contacting surface of the anvil assembly by at least one anchor. A loading unit includes a surgical buttress releasably secured to an anvil assembly and/or a staple cartridge secured thereto by at least one anchor, and a drive assembly including a knife blade, wherein movement of the drive assembly from a proximal position to a distal position results in the knife blade cutting the at least one anchor and freeing each surgical buttress from the anvil assembly and/or cartridge assembly.

An end effector for use by a surgeon to staple an anatomical structure of a patient during a surgical procedure includes an anvil and a cartridge. Each of the anvil and the cartridge has a face that is positionable on the anatomical structure. The anvil is coupled to the cartridge at first and second ends. The anvil is movable relative to the cartridge to define a first gap between the faces at the first ends that is different from a second gap between the faces at the second ends.

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.
