Abstract

A system and method for abdominal surgery is disclosed. The system can have one or more end effectors that can be attached to an introducer and/or tray and inserted into the abdomen through a large puncture through the patient's umbilicus. The end effector can have a surgical tool, such as a grasper. The system can have a manipulatable control arm that can be inserted into the abdomen through a small puncture through the patient's body wall. The end effector can be attached to the control arm and simultaneously or concurrently detached from the introducer or tray. The control arm can then manipulate the end effector to perform the surgery.
