Surgical device and methods

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.

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.
