The surgical access port has a cannula defining a hollow cannula shaft, and a tapered hub attached to a proximal end of the cannula. The tapered hub includes at least one inner ring configured to abut against the at least one recess or finger while the surgical instrument is inserted into the cannula of the surgical access port.

A surgical stapling instrument includes an end effector, an adapter assembly, and a rotation lockout assembly. The end effector includes a staple cartridge assembly and an anvil assembly that are coupled to a proximal housing and movably positioned relative to one another. The staple cartridge assembly has a drive beam and a sled. The sled carries a knife that is rotatably supported on the sled. The drive beam is configured to move the knife relative to the drive beam. The adapter assembly has an elongated shaft that extends distally to an articulating assembly. The articulating assembly includes distal and proximal joint members coupled by a pin to articulate the end effector. The rotation lockout assembly prevents rotation of the end effector during a firing of the surgical stapling instrument.

Devices and methods for articulating a distal end of a surgical device are provided. In one exemplary embodiment, the device includes an articulation joint that includes both an inner guide and an outer sleeve. The inner guide includes one channel extending therethrough that receives both a cutting mechanism and a closure band. Further, an outer surface of the inner guide, in conjunction with the outer sleeve, can define two additional channels that each receive an articulation band for articulating an end effector coupled to the articulation joint. The outer surface of the inner guide can include a plurality of ribs that also help define the two additional channels. Further, the outer sleeve can include a plurality of slots formed in it to improve flexibility and stability. Additional configurations of articulation joints, and configurations of components of a surgical device, are also provided, as are methods for using the same.

A deployment mechanism for selectively deploying and retracting an energizable member and/an insulative member relative to an end effector assembly of a surgical instrument includes one or more actuators, a clutch assembly, and a drive assembly. The clutch assembly is configured to couple to the actuator(s) to provide rotational motion in the first direction in response to such rotation of the actuator(s) and to decouple from the actuator(s) in response to rotation thereof in the second direction. The drive assembly is operably coupled to the clutch assembly and is configured to convert the rotational motion provided by the clutch assembly into longitudinal motion to translate the energizable member and/or insulative member from a storage position to a deployed position and to translate the energizable member and/or the insulative member from the deployed position back to the storage position.

An articulated instrument and method of its manufacture includes a plurality of segments connected to one another end-to-end, each having a hollow tubular shape defined by a wall, the wall comprising three or more rectangular panels connected along their respective edges at acute angles. A plurality of tendons extends at least partially through the plurality of segments and is configured to apply tension that selectively causes two adjacent segments from the plurality of tendons to bend relative to one another along a pivot joint disposed between the two adjacent segments. The plurality of segments is formed by staggered rectangular portions of a single sheet of stock material, each rectangular portion being folded to form the hollow tubular shape and connected to an adjacent rectangular portion by a tab, each tab defining a respective pivot joint.

A device for use in laparoscopic surgery is provided. The device has a plurality of telescoping sections positioned in and movable relative to a protective sheath between an extended configuration, wherein a body section of a first one of the telescoping sections is spaced apart from a body section of a second one of the telescoping sections, and a retracted configuration wherein the body section of the first one of the telescoping sections is in contact with the body section of the second one of the telescoping sections. A tissue interaction portion is configured to interact with tissue in response to the manipulation of a device actuator.

A surgical instrument including a housing, an endoscopic portion, a drive motor, a drive tube, a firing rod and an end effector is disclosed. The endoscopic portion extends distally from the housing and defines a first longitudinal axis. The drive motor is disposed at least partially within the housing. The drive tube is disposed in mechanical cooperation with the drive motor and is rotatable about a drive tube axis extending through the drive tube. The firing rod is disposed in mechanical cooperation with the drive tube and at least a portion of the firing rod is translatable with respect to the drive tube. The end effector is disposed adjacent a distal portion of the endoscopic portion and is in mechanical cooperation with the firing rod so that the firing rod drives a surgical function of the end effector.
