    Abstract: Surgical instruments having a rotary drive that can selectively actuate multiple end effector functions are described herein. In at least one embodiment, a surgical instrument includes a shaft, an end effector coupled to the shaft, a rotatable drive shaft coaxially disposed within an inner lumen of the shaft, and a plurality of selectively engageable clutches configured to transfer torque from the rotatable drive shaft to the end effector. Each of the clutches is configured to convert the rotation of the drive shaft into one of a plurality of movements of the end effector relative to the outer shaft.

    Abstract: In various embodiments, a shaftless end effector is disclosed. The end effector can comprise an anvil assembly including a staple forming surface. The end effector can also comprise a staple cartridge channel configured to receive a staple cartridge therein. The end effector can include a closure system configured to close the anvil. In various instances, the closure system can also form the staples contained within the staple cartridge. The end effector can also include a cutting member configured to cut tissue positioned intermediate the anvil and the staple cartridge. In various instances, the cutting member can be actuated by the closure system. In other instances, the end effector can include an independent system for actuating the cutting member. In various instances, the end effector can be delivered to a surgical site through a trocar and then operated by one or more actuators that are assembled to the end effector.

    Abstract: An input control device can be configured to operate in different modes depending on proximity data provided by a proximity detection system. The input control device can include a feedback generator configured to generate feedback in response to the input control device switching between operational modes, the proximity data provided by the proximity detection system, and/or other conditions of the surgical procedure, robotic surgical tool, surgical site, and/or patient. The input control device can include a variable resistance assembly for resisting input control motions applied to an actuator thereof. Additionally or alternatively, the input control device can include an end effector actuator assembly for repositioning the end effector actuator based on feedback from a paired robotic surgical tool.

    Abstract: A staple cartridge comprising a cartridge deck, a longitudinal slot defined within the staple cartridge, staple cavities defined in the deck, and a tissue thickness compensator is disclosed. The tissue thickness compensator comprises lumens. Each of the lumens comprise a cross-section and are formed by a tubular element. The lumens are laterally-oriented and spaced on the cartridge deck along the longitudinal axis of the staple cartridge. Each lumen extends across the width of the staple cartridge such that each lumen overlaps a plurality of the staple cavities and the longitudinal slot. The lumens are configured to collapse when pressure is applied to the lumens during a firing motion.

    Abstract: An end effector for use with a surgical instrument includes a lower jaw, an anvil, and a resilient member. The anvil is pivotable relative to the lower jaw between a fully opened position and a fully closed position. The resilient member is configured to bias the anvil to remain in the fully opened position when the anvil is in the fully opened position. The end effector may include a closure ring coupled with the anvil that is translatable relative to the lower jaw and configured to engage the anvil at an interface as the closure ring translates proximally relative to the lower jaw to thereby pivot the anvil relative to the lower jaw toward the fully opened position. In various embodiments, the resilient member may comprise elastomeric material positioned between the closure ring and the anvil or a pair of springs or resilient arms that engage the anvil.

    Abstract: An apparatus comprises a body, a shaft assembly, an end effector, a cartridge, and a staple driver actuator. The end effector is operable to manipulate tissue. The end effector comprises a lower jaw, a pivotable anvil, and a translating cutter. The translating cutter is operable to translate relative to the lower jaw and the anvil when the anvil is pivoted toward the lower jaw to manipulate tissue. The cartridge is insertable into the lower jaw and includes a plurality of staples. The staple driver actuator is disposed within the cartridge. The staple driver actuator comprises a secondary cutting element. The translating cutter of the end effector is operable to drive the staple driver actuator distally to staple and cut tissue substantially simultaneously.

    Abstract: A circular stapler apparatus for stapling tissue has a circular stapling head operable to drive staples toward an anvil to form the staples in a circular array. The anvil includes an anvil head, a proximal shaft extending proximally from the anvil head and having a proximal end disposed in a first plane, and a first pivot connecting the anvil head to the proximal shaft. The first pivot is operable to be disposed in a second plane that is laterally offset from the first plane. The anvil is configured to rotate via movement through multiple pivot points. The anvil may be configured to rotate to a position in which a portion of the anvil head is disposed below the first pivot and between the first pivot and the proximal shaft such that the anvil head is acutely angled with respect to a longitudinal axis of the proximal shaft.
