摘要： A surgical stapling instrument includes an anvil assembly, a reload assembly, an adapter assembly, a processor, and a memory including instructions stored thereon. When clamping to a target pressure, the instructions cause the surgical stapling instrument to advance the anvil assembly in relation to a staple cartridge supported on the reload assembly to a first position to define a first tissue gap within a predetermined acceptable range of tissue gaps, measure a first force of tissue compression of tissue clamped within the first tissue gap with the anvil assembly in the first position, and enter a firing mode of the surgical stapling instrument if the first force of tissue compression is within a predetermined acceptable range of tissue compressions.

摘要： A method for powered surgical stapling instrument rotation adjustment includes measuring a change in position of a first motor shaft of the surgical stapling instrument relative to a stored rotation verification position of the first motor shaft resulting from manual rotation of an adapter assembly of the surgical stapling instrument in relation to a handle assembly of the surgical stapling instrument, determining a distance traveled by a first drive assembly of the adapter assembly of the surgical stapling instrument resulting from the change in position of the first motor shaft, comparing the determined distance traveled to a first stored rotation verification position of the first motor shaft, determining if the compared distance falls into a predetermined acceptable range of rotation positions, and adjusting the position of the drive shaft if the compared distance is not within the predetermined range

摘要： A method of operating a surgical stapler includes advancing a knife assembly at a first velocity until a predetermined force is detected, advancing the knife assembly at a second velocity when the predetermined force is detected, the second velocity being less than the first velocity, and continuing to advance the knife assembly at the second velocity until the knife assembly travels a cutting stroke distance.

摘要： A surgical device including a handle assembly, an elongated portion, an end effector, a drive shaft, and a wick is disclosed. The wick is disposed within an outer sleeve of the elongated portion and is made from a fibrous material. The wick is configured to transfer moisture from a first portion of the wick to a second portion of the wick.
