A surgical instrument can comprise a first jaw, a second jaw comprising a fastener cartridge, and a closing system. The closing system can comprise a closure member configured to engage the first jaw and move the first jaw toward the second jaw. A pivot can pivotably couple the first jaw to the second jaw. The closure member can engage the first jaw at a location which is distal with respect to the pivot. The closure member and the first jaw can include a cam pin/cam slot arrangement which increases the leverage or mechanical advantage that the closure member applies to the first jaw as the first jaw is moved from an open position to a closed position. The surgical instrument can further comprise a first motor configured to operate the closing system and a second motor configured to operate a firing system configured to eject fasteners from the fastener cartridge.

In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.

A surgical instrument can comprise a handle, a motor, and a shaft extending from the handle. The handle and/or the shaft can define a longitudinal axis. The surgical instrument can further comprise a fastener cartridge comprising a plurality of fasteners removably stored therein, an anvil configured to deform the fasteners, a closure drive configured to move the anvil toward and away from the fastener cartridge which is rotatable about the longitudinal axis, and a firing drive configured to deploy the fasteners from the fastener cartridge which is rotatable about the longitudinal axis. The surgical instrument can further comprise a transmission comprising a first operating configuration which connects the motor to the closure drive and a second operating configuration which connects the motor to the firing drive.

A piece of buttress material (936) and an end-effector of a surgical instrument including features which can aid a surgeon in properly and quickly attaching the piece of buttress material (936) to the end-effector. In various embodiments, a piece of buttress material (936) can include retention features (910) which can be engaged with portions of an end-effector to releasably retain the piece of buttress material (936) to at least a portion of the end-effector. Similarly, an end-effector can include features (910) configured to engage portions of a piece of buttress material (936) to releasably retain the piece of buttress material (936) to the end-effector. In at least one embodiment, more than one piece of buttress material can be releasably retained to an end-effector.
摘要:
A surgical stapling apparatus. Various embodiments include a rotatable elongated body that extends from a rotatable shroud on handle assembly and has a distal end configured for attachment to a disposable loading unit. The apparatus further includes a lockable rotation system for selectively locking the rotatable shroud to prevent rotation thereof about a longitudinal axis.

A surgical instrument system can comprise, one, a surgical instrument (9000) including a handle, a shaft (9040) comprising a distal end, and a trigger (9014) and, two, an end effector (9060) attachable to the shaft. The instrument can further include a firing member and a motor (100) configured to move the firing member (9020) toward the distal end, wherein the trigger is configured to operate the motor. The surgical instrument system can further include a plurality of sensors configured to detect one or more error conditions, a plurality of indicators, and a controller in communication with the plurality of sensors and the indicators, wherein the controller is configured to selectively activate the indicators to indicate the error conditions detected. A surgical instrument can comprise a plurality of actuators and a plurality of actuator locks, wherein the controller can actuate one or more of the actuator locks to indicate the error condition detected.
摘要:
Coupling systems for removably coupling dual rotary drive shafts of a surgical instrument to corresponding driven shafts of a surgical end effector. The surgical instrument may include a first rotary drive shaft that includes a first drive shaft axis and a second rotary drive shaft that includes a second drive shaft axis. The second drive shaft axis may be offset from and parallel with the first drive shaft axis. The coupling systems may facilitate simultaneous operable attachment of the first and second drive shafts of the surgical instrument with corresponding first and second driven shafts of a surgical end effector such that rotation of the first drive shaft rotates the first driven shaft and rotation of the second drive shaft rotates the second driven shaft.

A surgical instrument system is disclosed. The surgical instrument system can include a handle and a plurality of shafts which can be selectively assembled to the handle. Each shaft can include a system of sensors which can direct the operation of the handle during use.
摘要:
A surgical instrument can comprise an end effector, a first drive configured to perform a first end effector function, a second drive configured to perform a second end effector function, and a rotatable shaft. The rotatable shaft can comprise a first thread, wherein the first drive is engageable with the first thread to perform the first end effector function, and a second thread, wherein the second drive is engageable with the second thread to perform the second end effector function, and wherein the first thread is at least partially coextensive with or overlaps the second thread.
摘要:
A surgical instrument, such as an endoscopic or laparoscopic instrument. The surgical instrument may comprise an end effector (12) comprising at least one sensor (368). The surgical instrument may also comprise an electrically conductive shaft (8) having a distal end connected to the end effector (12) wherein the sensor (368) is electrically insulated from the shaft (12). The surgical instrument may also comprise a handle connected to a proximate end of the shaft (12). The handle may comprise a control unit (300) electrically coupled (400) to the shaft such that the shaft (8) radiates signals as an antenna from the control unit (300) to the sensor (368) and receives radiated signals from the sensor (368). Other components electrically coupled to the shaft may also radiate the signals.
