Abstract
The following quote was obtained by the news editors from the background informa tion supplied by the inventors: “This invention relates to surgical cannulas, an d more particularly, to a surgical cannula for introducing multiple minimally in vasive surgical instruments through a single opening in the body.“Minimally invasive surgery (MIS) (e.g., endoscopy, laparoscopy, thoracoscopy, c ystoscopy, and the like) allows a patient to be operated upon through small inci sions by using a camera and elongated surgical instruments introduced to an inte rnal surgical site.The surgical site often comprises a body cavity, such as the patient’s abdomen.The body cavity may optionally be distended using a clear fl uid such as an insufflation gas.In traditional minimally invasive surgery, the surgeon manipulates the tissues by using hand-actuated end effectors of the elon gated surgical instruments while viewing the surgical site on a video monitor.
