Abstract
An apparatus includes a proximal structure configured to be positioned extracorporeally relative to a patient, 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 primary structure to define a primary axis and a working channel sized and configured to receive and guide a surgical scope shaft distally therethrough along the primary axis. The proximal structure has a greater maximum dimension in a direction transverse to the primary axis than the distal structure. The apparatus further includes an articulation feature at a distal end of the distal structure that is configured to articulate relative to the proximal structure to direct the surgical scope shaft along a secondary axis that is angled relative to the primary axis.
