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.

Claims

1. A method for surgery in a body comprising:

attaching a tool to an introducer outside of the body, wherein the tool has a tool longitudinal axis;

inserting a control element into the body through a second access site;

inserting the introducer through a first access site,

attaching the tool inside of the body to the control element; and

detaching the introducer from the tool, wherein attaching the tool to the control element is concurrent with detaching the introducer from the tool.

2. The method of claim 1, further comprising attaching outside of the body the introducer to an effector comprising a rotating portion and a non-rotating portion.

3. The method of claim 2, wherein attaching the tool to the control element comprises rotating at least the rotating portion of the effector with respect to the non-rotation portion of the effector.

4. The method of claim 1, wherein the second access site is smaller than the first access site.

5. The method of claim 1, further comprising performing a treatment with the tool at a target site in the body;

reattaching the tool to the introducer; and

removing the introducer through the first access site.

6. The method of claim 5, further comprising removing the control element through the second access site.

13. The method of claim 1, wherein inserting the introducer through the first access site comprises inserting the introducer and the tool through the first access site.

14. The method of claim 1, wherein the introducer is separate from the tool after the tool is attached to the control element.

15. The method of claim 1, wherein inserting the introducer into the body through the first access site comprises inserting an effector through the first access site.

35. 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, and wherein the effector is attached to the working tool; and

a control element;

wherein the first connector is configured to releasably attach the effector to the introducer, and wherein the second connector is configured to releasably attach the effector to the control element.

36. The device of claim 35, wherein the introducer is separate from the tool after the tool is attached to the control element.

37. The device of claim 35, wherein the control element comprises a shaft.

38. The device of claim 35, wherein the rotating-locking element is configured to lock the first connector and the second connector.

41. The device of claim 35, wherein the working tool comprises a grasper.

42. The device of claim 35, wherein the control element has a smaller diameter than a diameter of the effector.

43. The device of claim 35, wherein the control element comprises a first shaft and a second shaft coaxial with the first shaft.

44. The device of claim 43, wherein the first shaft is configured to activate the working tool when the first shaft slides with respect to the second shaft.

45. (canceled)

46. A method for introducing multiple end effectors into the abdominal cavity of a patient, comprising:

mounting a holder onto a laparoscope, and wherein the holder comprises multiple end effectors;

articulating the holder with respect to the laparoscope, wherein articulating comprises articulating the holder into a first low-profile position when the holder is outside of the patient; and

wherein articulating further comprises when the holder is inside the abdominal cavity articulating the holder to a second position where the holder is visible by the camera.

47. A holder that allows for a end effector to be locked to a holder:

wherein the end effector is configured to only be unlocked from the holder by a trans-corporeal component; and

wherein the end effector is configured to only be locked into the holder when the end effector is delivered into the holder by the trans-corporeal component and subsequently rotated.
