A single port surgical method comprises inserting only a single trocar through the abdominal wall; inserting a camera into the abdominal cavity; magnetically anchoring the camera to the abdominal wall; obtaining a first instrument comprising an elongate shaft with a distal end and a proximal end connected to a first handle; passing the distal end of the first instrument through the abdominal wall independent of a trocar; attaching in vivo an end effector to the distal end of the first surgical instrument; obtaining a second instrument comprising an elongate shaft with a distal end with an end effector and a proximal end connected to a second handle; passing the distal end of the second instrument through the trocar; and manipulating tissue in the abdominal cavity with the first and second surgical instrument end effectors under visualization from the magnetically anchored camera.
