A surgical stapling instrument comprising a modular end effector and a housing assembly is disclosed. The modular end effector comprises a closure beam to receive a staple cartridge therein, a rotatable closure driver, a firing bar comprising a knife, and a rotatable firing driver. The closure beam is translatable through a closure stroke based on rotation of the rotatable closure driver, and the firing bar is translatable through a firing stroke based on rotation of the rotatable firing driver. The modular end effector is selectively coupleable to the housing assembly between a coupled configuration and an uncoupled configuration, and the modular end effector comprises a closure actuator and a firing actuator. The rotatable closure driver and the rotatable firing driver are to rotate based on the modular end effector being coupled to the housing assembly and actuation of the closure actuator and the firing actuator, respectively.

Surgical instruments having modular end effector selectively coupleable to housing assembly

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.

End effector coupling arrangements for a surgical cutting and stapling 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.

Powered surgical stapler

A surgical access device includes a cannula and a housing coupled to the cannula. A cannula lumen and a housing interior communicate to define a working channel that extends along a central axis of the device between proximal and distal device ends. A needle entrance port is arranged on a side portion of the housing and opens to the working channel. A needle exit port is arranged distally of the needle entrance port on a side portion of the cannula, and communicates with the needle entrance port to define a suture path extending through the surgical access device at an oblique angle relative to the central axis. The needle ports are configured to guide a suture passer device distally through the surgical access device and first and second tissues of different thicknesses, while maintaining the same tissue bite distance in each of the first and second tissues.

Trocar with oblique needle insertion port and perpendicular seal latch

A surgical system comprising an electric motor and a surgical instrument is disclosed. The surgical instrument comprises a housing, a shaft extending from the housing, a fastener cartridge, an anvil, a translatable drive member, and a rotatable actuator knob. The housing comprises an input shaft operably coupled to the electric motor. The input shaft is rotatable in a first mode by the electric motor. The fastener cartridge comprises a plurality of fasteners removably stored therein. The anvil is configured to deform the fasteners. The translatable drive member is configured to move the anvil toward and away from the fastener cartridge. The translatable drive member is movable by the electric motor in the first mode. The rotatable actuator knob is configured to be rotated multiple full rotations in a second mode to manually cause the input shaft to move the anvil.

Stapling assembly comprising a retraction drive

Stapling assembly comprising a shiftable drive

An apparatus comprises an end effector, a shaft assembly, and an interface assembly. The end effector is operable to manipulate tissue, the shaft assembly is in communication with the end effector and a portion of the shaft assembly extends proximally from the end effector. The interface assembly is in communication with the shaft assembly. The interface assembly comprises a housing portion, a shaft cartridge, and a base portion. The housing portion can engage the shaft cartridge. The shaft cartridge is able to rotate and articulate the end effector, and the shaft assembly extends from the shaft cartridge. The base portion and the housing portion are able to enclose the shaft cartridge.

Electrosurgical device with disposable shaft having modular subassembly

A method of suturing a trocar path incision in a tissue of a patient with an obturator includes inserting the obturator through the tissue such that a shaft of the obturator extends through a tissue opening about the trocar path incision and a distal tip of the obturator is positioned within a cavity of the patient. The method also includes directing the suture via a suturing feature with the obturator inserted through the tissue in order to direct the suture relative to the tissue. Furthermore, the method includes closing the tissue opening about the trocar path incision with the suture.

Method of suturing a trocar path incision

An apparatus comprises an end effector, a shaft assembly, and an interface assembly. The end effector is coupled with the shaft assembly. The shaft assembly comprises a translating member extending through the shaft assembly. The interface assembly is operable to engage the shaft assembly and comprises a plurality of drive shafts and a rack. One of the drive shafts is operable to drive the rack along a path that is parallel to the longitudinal axis of the shaft assembly. A plurality of racks may be used to rotate the shaft assembly, articulate the shaft assembly, and/or drive the translating member through the shaft assembly to thereby actuate the end effector.

Electrosurgical device with disposable shaft having rack and pinion drive

A surgical device for operating on tissue comprises an end effector, a shaft, and an interface assembly. The shaft comprises an articulation section operable to provide deflection of the end effector relative to the longitudinal axis of the shaft. The interface assembly comprises a plurality of pulleys associated with drive shafts driven by an external system. The pulleys are operable to cause rotation of one or both of the shaft or end effector. The pulleys are further operable to cause articulation of the articulation section. The interface assembly further comprises drive components operable to cause movement of components of the end effector.
