The Development of the Supermicroinvasive Magnetic Anchoring Laparoscopic System

A magnetic anchoring supermicroinvasive laparoscopic system, including in vitro magnetic navigation handle and in vivo magnetic anchor laparoscopy is introduced. The magnetic anchor laparoscopic comprises an outer cannula, two data lines, a camera, a high color temperature LED light and two inner magnets. It is tiny enough to enter the abdominal cavity through conventional laparoscopic trocar and achieve orientation, navigation as wel as adjustment thefi eld of view within the abdominal cavity by attracting with the in vitro magnetic handle, thus it does not take up space of the laparoscopic trocar in working state. The system which can not only apply in single-port laparoscopic surgery based on a single traditional laparoscopic trocar but also apply in traditional laparoscopic surgery with less trocar, wil enhance the extent of minimaly invasive surgery and reduce the operation diffi culty at the same time. The clinical application of the system wil optimize the minimaly invasive techniques and benefi t the patients.
