  • Surgical robotic devices and systems for use in performing minimally invasive and natural orifice transluminal endoscopic surgical actions
    Patent number: 11925425
    Abstract: 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.

  • Robotic devices and systems for performing single incision procedures and natural orifice translumenal endoscopic surgical procedures, and methods of configuring robotic devices and systems
    Patent number: 11918311
    Abstract: Example embodiments relate to surgical systems. The system includes an end-effector assembly having an instrument. The system includes a first arm assembly. A distal end of first arm assembly is securable to the end-effector assembly. The system includes an elbow joint assembly. A distal end of elbow joint assembly is secured to a proximal end of first arm assembly. A proximal end of elbow joint assembly is secured to a distal end of second arm assembly. The second arm assembly includes a first elbow drive assembly. The first elbow drive assembly includes an integrated motor for driving the elbow joint assembly to pivotally move the first arm assembly relative to an axis. The second arm assembly also includes a second elbow drive assembly. The second elbow drive assembly includes an integrated motor for driving the elbow joint assembly to pivotally move the first arm assembly relative to another axis.
