Example embodiments relate to surgical systems and methods. The system includes an arm assembly and end-effector assembly. The arm assembly includes a first drive portion and wrist drive portion. The end-effector assembly is securable to and removable from the arm assembly. The end-effector assembly includes an instrument assembly and wrist assembly. The instrument assembly includes a first instrument, first instrument driven portion, and first instrument insulative portion. The first instrument driven portion is configured to move the first instrument relative to a first axis when the first instrument driven portion is driven by the first drive portion. The wrist assembly includes a wrist driven portion. The wrist driven portion is configured to move the first instrument relative to a second axis when the wrist driven portion is driven by the wrist drive portion. The end-effector assembly is secured to and removable from the arm assembly via a wrist connector portion.

Surgical robotic devices and systems for use in performing minimally invasive and natural orifice transluminal endoscopic surgical actions

Embodiments relate to robotic arm assemblies. The robotic arm assembly includes an end-effector assembly. The end-effector assembly includes an instrument assembly. The instrument assembly includes an instrument and instrument driven portion. The elongated body includes an instrument central axis. The instrument driven portion includes a first central axis. The instrument driven portion is secured to a proximal end of the instrument in such a way that, when the instrument driven portion is driven to rotate, the instrument rotates relative to the first central axis. The end-effector assembly includes an instrument drive assembly. The instrument drive assembly includes an instrument drive portion. The instrument drive portion includes a second central axis. The instrument drive portion is configured to drive the instrument driven portion to rotate the distal end of the instrument relative to the first central axis. The second central axis intersects with and orthogonal to the first central axis.

Robotic arm system with gear-driven end-effector assembly

Example embodiments relate to surgical devices, systems, and methods. The system may include a port assembly. The port assembly may be for use with a surgical arm assembly having a surgical arm and elongated anchor section. The port assembly may include a first main body having an elongated body and a main channel. The main channel may be formed by a portion of an interior surface of the elongated body. The main channel may extend between the proximal and distal ends of the elongated body. The first main body may include an instrument gate secured at a proximal end of the main channel. The instrument gate may include an expandable opening configured to be in a persistently closed position. The expandable opening may be configurable to adaptively expand to a shape of a cross-section of a surgical arm when the surgical arm is inserted through the expandable opening.

Port assembly for use with robotic devices and systems to perform single incision procedures and natural orifice translumenal endoscopic surgical procedures

Embodiments relate to robotic arm assemblies. Robotic arm assembly includes an arm segment and end-effector assembly. Arm segment includes an elongated body which forms an arm segment central axis. End-effector assembly is securable to the arm segment. End-effector assembly includes an instrument assembly and first gear assembly. Instrument assembly includes an instrument and instrument gear. Instrument forms an instrument central axis. Instrument is for performing an action. Proximal end of instrument is secured to the instrument gear. First gear assembly includes a first primary gear and protrusion portion. First primary gear includes a second central axis formed through the first primary gear. Second central axis intersects with first central axis, instrument central axis, and arm segment central axis. Protrusion portion is secured to the first primary gear, and includes an opening. A portion of the proximal end of the instrument is provided in the opening and rotatable within the opening.

Example embodiments relate to surgical systems and methods. System includes an end-effector assembly and arm assembly. End-effector assembly includes an instrument assembly and wrist assembly. Instrument assembly includes an instrument and instrument driven portion. Instrument driven portion includes an instrument connection portion and instrument driven gear. Instrument connection portion connects the instrument driven gear to the instrument. Wrist assembly includes a wrist driven gear and wrist body, which connects the wrist driven gear to the instrument assembly. Arm assembly includes a wrist connector portion and integrated motors. Arm assembly attaches to and detaches from the wrist assembly. When the arm assembly is attached to the wrist assembly, the instrument driven gear and wrist driven gear are drivable to rotate by the integrated motors. When the arm assembly is detached from the wrist assembly, the instrument driven gear and wrist driven gear are not drivable to rotate by the integrated motors.

Example embodiments relate generally to robotic arm assemblies. The robotic arm assembly may include an arm segment and an end-effector assembly. The arm segment may include an elongated body, a first motor, and a second motor. The end-effector assembly may be securable to the arm segment. The end-effector assembly may include an instrument assembly, a first gear assembly, and a second gear assembly. The instrument assembly may include an instrument and an instrument gear. The first gear assembly may include a first primary gear and a protrusion portion. The protrusion portion may be configurable to drive the instrument assembly. The second gear assembly may include a second primary gear configurable to drive the instrument gear.

Example embodiments relate to surgical devices, systems, and methods. The system may include an end-effector assembly. The end-effector assembly may comprise an instrument assembly and a wrist assembly. The instrument assembly may comprise an instrument for performing a surgical action. The instrument assembly may further comprise an instrument driven portion configurable to be driven in such a way as to move the instrument relative to a first axis. The instrument assembly may further comprise an instrument insulative portion providable between the instrument and the instrument driven portion. The instrument insulative portion may be configurable to electrically isolate the instrument from at least the instrument driven portion when the instrument insulative portion is provided between the instrument and the instrument driven portion. The wrist assembly may include a wrist driven portion configurable to be driven in such a way as to move the instrument relative to a second axis.
