    摘要： The present invention discloses a surgical stapler instrument. The surgical stapler instrument comprises a handle assembly having a proximal end and a distal end. A bottom jaw is detachably coupled to the distal end of the handle assembly. The bottom jaw having a staple cartridge surface, configured to eject one or more staples. Further, a top jaw is detachably coupled to the bottom jaw toward the distal end of the handle assembly. The top jaw comprises a staple pocket disposed over an anvil surface of the top jaw and configured to bend the ejected one or more staples and deliver into targeted tissues. An effective friction coefficient (μe) of the staple pocket of the top jaw is lower than the staple cartridge surface of the bottom jaw to achieve optimized stapling.

    摘要： A medical system includes a device for removing an object in a body cavity, the device including a shaft portion including a rotatable drive shaft, a motor configured to rotate the drive shaft, and a cutter attached to a distal end of the drive shaft and configured to perform a cutting operation on the object when the drive shaft is rotated by the motor. The medical system further includes one or more sensors each configured to detect a physical quantity related to the cutting operation, and a controller configured to determine one or more cutting parameters for the cutting operation based on the physical quantity detected by each of the sensors, and control the motor to rotate the drive shaft according to the determined cutting parameters.

    摘要： A surgical stapling instrument includes an elongate body portion defining a longitudinal axis, an end effector supported on a distal portion of the elongated body portion, and a deployment member extending from the elongate body portion into the end effector. The end effector includes a housing having a base portion and a jaw portion, an anvil assembly supported on the jaw portion, and a cartridge assembly releasably supported on the base portion. The cartridge assembly includes an alignment pin assembly. The deployment member includes a distal portion supporting an abutment member and is movable between a retracted position and an advanced position. The abutment member is releasably coupled to the alignment pin assembly when the deployment member is in the retracted position and is fixedly secured to the alignment pin assembly when the deployment member is moved from the retracted position.
