Magnetic retraction system for laparoscopic surgery and method of use thereof
First Claim
1. A magnetic retraction system for assisting in laparoscopic surgery on a patient, said system comprising:
- a) an articulatable arm;
b) a securing member for securing one end of said articulatable arm to a support member;
c) a magnet which is disposed at another end of said articulatable arm, for applying a magnetic field around a defined area below said another end of said articulatable arm, said magnet including an upper magnetic pole;
d) a patient adapted to be disposed below said upper magnetic pole, said patient having ingested a magnetizable or magnetic element whereby, when said patient is disposed prone below said upper magnetic pole, a lower opposite magnetic pole is induced in said patient through polarization of magnetizable material within the intestine of said patient; and
e) a controllable element which is operatively-associated with said upper pole and which is selectively-controllable to vary the magnetic field, and/or adjust the upper pole in height above said patient, and/or tilt, and/or roll.

Abstract
A novel magnetic retraction system is provided herein. The magnetic retraction system includes magnetic means for applying a magnetic field around a defined area of the magnetic retraction system. An articulatable support is provided for such magnetic means. The magnetic means includes an upper (North) magnetic pole. A lower (South) magnetic pole is induced in the intestine of a patient into which has been introduced a magnetic or magnetizable material. The induced lower pole is spaced a selectable spaced distance from the upper (North) magnetic pole. The upper pole may have its strength and/or the orientation of its magnetic field varied to adjust and/or to manipulate the intestine.
