ABSTRACT:
An introducer is shown and described which includes a number of unique and useful features designed to improve the process of obtaining access to a bodily cavity for the purpose of performing minimally invasive surgical procedures, particularly laparoscopic procedures. These features include, among others, a sharpened cannula distal end, in order to assist entry of the introducer through the tissue barrier into the bodily cavity, a substantially transparent support disk so that visual access to the insertion site is maintained at all times, a septum seal designed to sealingly receive instruments having a cross-sectional dimension of 2.2 mm or less, an improved anchoring device which is simply and manually actuated and is of an advantageous three-slit design, and a simple, side-mounted gas insufflation port, usable at all times during the procedure and adapted for connection to gas tubing fitted with a pinch clamp for easy control of the gas flow.
