Systems, methods, and instrumentalities are disclosed for switching a control scheme to control a set of system modules and/or modular devices of a surgical hub. A surgical hub may determine a first control scheme that is configured to control a set of system modules and/or modular devices. The surgical hub may receive an input from one of the set of modules or a device located in an OR. The surgical hub may make a determination that at least one of a safety status level or an overload status level of the surgical hub is higher than its threshold value. Based on at least the received input and the determination, the surgical hub may determine a second control scheme to be used to control the set of system modules. The surgical hub may send a control program indicating the second control scheme to one or more system modules and/or modular devices.

A surgical stapling device includes tool assembly having an anvil and a cartridge assembly. The cartridge assembly includes a channel member that defines a cavity, a staple cartridge supported within the cavity of the channel member, and a biasing member. The staple cartridge supports staples, each having a back span and a pair of legs depending from the back span. The biasing member is positioned within the channel member and is deformable to allow the cartridge body to move vertically within the cavity of the channel member. The anvil incudes staple deforming pockets that are configured to deform the legs of the staples from a position within the same plane as the back span to positions laterally offset from the back span.

A surgical device is disclosed which includes a handle portion, a central body portion and a SULU. The SULU includes a proximal body portion, an intermediate pivot member and a tool assembly. The intermediate pivot member is pivotally secured to the proximal body portion about a first pivot axis and the tool assembly is pivotally secured to the intermediate pivot member about a second pivot axis which is orthogonal to the first pivot axis. The SULU includes a plurality of articulation links which are operably connected to the tool assembly by non-rigid links. The articulation links are adapted to releasably engage articulation links positioned in the central body portion. The body portion articulation links are connected to an articulation actuator which is supported for omni-directional movement to effect articulation of the tool assembly about the first and second axes. The handle portion includes a spindle and barrel assembly drive mechanism for advancing and retracting a drive member positioned in the tool assembly. In one embodiment, the tool assembly includes a cartridge assembly having a plurality of staples and an anvil assembly.

A surgical cutting and stapling end effector. Various embodiments comprise a channel that is configured to operably support a removable staple cartridge. A rotary end effector drive shaft is supported within the channel and is configured to move a firing assembly longitudinally within the end effector to cause the sled to eject surgical staples from the staple cartridge. The firing assembly is prevented from moving distally through the channel unless a surgical staple cartridge that has a sled in a starting position has been seated within the channel.

Embodiments include an end effector including an anvil, the anvil having an anvil face, an anvil blade channel defined by the anvil face, a first pocket row of first row staple pockets, a second pocket row of second row staple pockets, a third pocket row of third row staple pockets, a fourth pocket row of fourth row staple pockets, a fifth pocket row of fifth row staple pockets, a sixth pocket row of sixth row staple pockets, a cartridge having a cartridge face defining a cartridge blade channel, the cartridge being configured to retain a plurality of staples, and a blade, the blade having a cutting edge, where the blade is movable from a first position at a distal end of the cartridge to a second position at a proximal end of the cartridge.

A method for characterizing a state of an end effector of an ultrasonic device is disclosed. The ultrasonic device including an electromechanical ultrasonic system defined by a predetermined resonant frequency. The electromechanical ultrasonic system further including an ultrasonic transducer coupled to an ultrasonic blade. The method including applying, by an energy source, a power level to the ultrasonic transducer; measuring, by a control circuit coupled to a memory, an impedance value of the ultrasonic transducer; comparing, by the control circuit, the impedance value to a reference impedance value stored in the memory; classifying, by the control circuit, the impedance value based on the comparison; characterizing, by the control circuit, the state of the electromechanical ultrasonic system based on the classification of the impedance value; and adjusting, by the control circuit, the power level applied to the ultrasonic transducer based on the characterization of the state of the end effector.

A method of surgical stapling that uses a surgical instrument operable to compress, staple, and cut tissue. The instrument includes a body, a shaft, and an end effector with a pair of jaws. A placement tip extends distally from one of the jaws of the end effector. The method includes positioning the end effector at a desired site for surgical stapling. The method also includes controlling one or more of the jaws of the end effector to place the end effector in an open position. The method also includes positioning the end effector such that tissue is located between the jaws. The method also includes clamping the tissue between the jaws by moving at least one of the jaws toward the other jaw. The method also includes advancing a firing beam of the apparatus from a proximal position to a distal position.

A surgical instrument comprising a first jaw, a second jaw rotatable relative to the first jaw, and a closure system for closing the second jaw is disclosed. The closure system comprises a multi-stage closure system. In at least one instance, the closure system comprises a first closure member which closes the second jaw quickly, but with low force, and a second closure member which closes the second jaw more slowly, but with a higher force.

A powered endoscopic surgical apparatus is provided and includes a handle including a housing, a power source supported in the housing; an endoscopic portion extending distally from the housing of the handle; an end effector assembly coupled to a distal end of the endoscopic portion, the end effector assembly including a pair of jaws configured to perform a surgical function; a driving member; a drive source including a motor powered by the power source and connected to the driving member; and a gear assembly engaged with the motor. The gear assembly including a gear rack provided on the driving member; and a main gear operatively connected with the gear rack, the motor spinning the main gear such that rotary motion of the main gear moves the driving member in an axial direction such that the driving member actuates the end effector to perform the surgical function.

The present disclosure provides a surgical instrument, such as a tissue sealing instrument, having a staple cartridge with a staple pusher and a staple; and a drive member configured to translate distally through the instrument. The drive member includes a lateral projection configured to engage the staple pusher and drive the staple into tissue. The lateral projection of the drive member has a height substantially less than the height of the staple cartridge, thereby requiring less clearance as it translates through the staple cartridge. In addition, the lateral projection has a smaller footprint than conventional drive members resulting in a more compact distal tip on the staple cartridge, which allows for a more compact and maneuverable surgical instrument.
