1. A method for surgery in a body comprising:
- attaching a tool to a distal end of an introducer outside of the body, wherein the tool has a tool longitudinal axis;
inserting a distal end of a control element into the body through a second access site;
inserting the introducer distal end into the body through a first access site until the tool is disposed adjacent the control element distal end; and
rotating a shaft element of the control element, thereby rotating one or more elements on the tool in a second direction relative to a non-rotating portion of the tool to simultaneously both lock the tool inside of the body to the control element distal end and unlock the tool from the introducer distal end.

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.

12. A device for surgery comprising:
-
an introducer; a working tool; an effector comprising a rotating-locking element comprising a first connector and a second connector rotatably mounted relative to a non-rotating portion of the effector, and wherein the effector is attached to the working tool; and a control element; wherein the rotating-locking element is rotatable between a first position wherein the first connector locks the effector to the introducer, and a second position, wherein rotation of the rotating-locking element to the second position simultaneously both causes the second connector to lock the effector to the control element and causes the first connector to unlock the effector from the introducer. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A device for surgery comprising:
-
an introducer rod or delivery system comprising an introducer distal end for introduction into a target site; an end effector including a working tool, and a rotating-locking element comprising a first connector and a second connector, and wherein the end effector is attached to the working tool; and a control element comprising a control shaft including a distal end for introduction into the target site; wherein the rotating-locking element is rotatable in a first direction relative to the end effector such that the first connector locks the end effector to the introducer distal end outside of a target site such that the introducer can deliver the end effector into the target site, and wherein the rotating-locking element is rotatable in a second direction to simultaneously both cause the second connector to lock the end effector to the distal end of the control shaft of the control element in the target site and cause the first connector to unlock the end effector from the introducer distal end. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
