摘要： An apparatus is configured to apply an adjunct material to a stapling surface of a jaw of a surgical stapler. The jaw includes an outer surface disposed opposite the stapling surface. The apparatus includes a housing and an arm. The housing includes a first contact feature that is configured to contact one of the adjunct material or the outer surface of the jaw. The arm is operatively coupled with the housing. The arm includes a second contact feature that is configured to move relative to the first contact feature to contact the other of the adjunct material or the outer surface of the jaw. The first and second contact features are configured to cooperate to apply a compression force in a direction toward the first contact feature to pinch the adjunct material against the stapling surface to mount the adjunct material to the stapling surface.

摘要： An apparatus includes a body, a shaft, a stapling head assembly, and an anvil. The body includes a motor, a first user input feature, and a second user input feature. The first user input feature is operable to activate the motor. The shaft extends distally from the body. The stapling head assembly is positioned at a distal end of the shaft. The stapling head assembly includes an anvil coupling feature, at least one annular array of staples, and a staple driver. The second user input feature is operable to drive the anvil coupling feature longitudinally. The staple driver is operable to drive the at least one annular array of staples. The motor is operable to drive the staple driver. The anvil is configured to couple with the anvil coupling feature. The anvil is further configured to deform the staples driven by the staple driver.

摘要： A staple cartridge for use with a surgical instrument is disclosed. The staple cartridge comprises an elongate slot extending from a proximal end toward a distal end, wherein the elongate slot defines a longitudinal axis, a cartridge body, and a deck surface. The staple cartridge further comprises a first longitudinal row of staple cavities defined in the cartridge body, wherein the first longitudinal row of staple cavities extends alongside the elongate slot. First cavity extenders protrude above said deck surface, wherein each first cavity extender surrounds a first section of a staple cavity from the first longitudinal row. The staple cartridge further comprises a second longitudinal row extending alongside the first longitudinal row of staple cavities. Second cavity extenders protrude above the deck surface, wherein each second protrusion surrounds a second section of a staple cavity from the second longitudinal row. The second section is different than the first section.

摘要： Devices and systems are provided for controlling movement of a working end of a surgical device by means of a robotic system. In one embodiment, systems and devices are provided for moving an end effector on a distal end of a surgical fastening device. Movement can include rotational movement of the end effector about an axis of the shaft, articulation of the end effector relative to the shaft, and actuation of an end effector, e.g., closing, firing, and/or cutting.

摘要： An ultrasonic surgical blade includes a body having a proximal end, a distal end, and an outer surface. The distal end is movable relative to a longitudinal axis in accordance with ultrasonic vibrations applied to the proximal end. At least a portion of the outer surface of the body comprises a lubricious coating adhered thereto. The lubricious coating has a coefficient of friction that is less than the coefficient of friction of the outer surface of the body.

摘要： Disclosed is a surgical instrument, comprising: an end effector configured to grasp tissue. The end effector comprises a jaw, and a staple cartridge seatable in the jaws, wherein the staple cartridge comprises a sensor array. The surgical instrument further comprises a power source configured to supply power to the staple cartridge, and a transmission system configured to wirelessly transmit at least one of the power and a data signal between the staple cartridge and the surgical instrument, and a control circuit. The control circuit is configured to detect a bandwidth of data transmission through the transmission system, detect a discharge rate of the power source, and select a sensor sampling rate of the sensor array based on a detected value of the bandwidth and a detected value of the bandwidth and a detected value of the discharge rate.

摘要： Various embodiments are directed to surgical instruments comprising an end effector, a shaft and a jaw assembly. The end effector may comprise an ultrasonic blade extending distally substantially parallel to a longitudinal axis. The shaft may extend proximally from the end effector along the longitudinal axis. The jaw assembly may comprise first and second jaw members. The jaw assembly may be pivotable about a first axis substantially perpendicular to the longitudinal axis from a first position where the first and second jaw members are substantially parallel to the ultrasonic blade to a second position. Additionally, the first and second jaw members may be pivotable about a second axis substantially perpendicular to the first axis.
