Abstract: An apparatus includes a proximal structure configured to be positioned extracorporeally relative to a patient and defining a primary axis, and a distal structure extending distally from the proximal structure and configured to be passed through a body wall and into a body cavity of the patient. The distal structure cooperates with the proximal structure to define a working channel sized and configured to receive and guide a surgical instrument distally therethrough. The distal structure includes a proximal portion and an angled distal portion. The angled distal portion defines a secondary axis that is angled relative to the primary axis. At least the angled distal portion of the distal structure is rotatable relative to proximal structure about the primary axis.

Abstract: Robotics surgical systems, instrument mounts, and endoscopes are disclosed. A robotic surgical system includes a robotic arm, an instrument mount arranged at a distal end of the robotic arm, and an endoscope comprising a housing and a shaft. The housing is configured to be mounted to the instrument mount, and the shaft extends from the housing in a distal direction. A cable is connected to the housing and extends from the housing in a distal direction and along a lateral side of the housing.

Abstract: A surgical system can include a master controller for controlling one or more surgical tools, The system can also include an input on the master controller configured to change the master controller from a first mode into a second mode. The first mode can be a teleoperation mode and the second mode can be a virtual marking mode. In the virtual marking mode, a user is capable of communicating a virtual marker to other staff.
