Abstract
A headless, flexible, two-part, semi-flexible trocar is formed from two semi-circular sections to form a hollow tubular body having a flared proximal end and a tapered distal end. The sections may temporarily move with respect to one another to increase the diameter of the tubular structure. A top portion protruding beyond the body may readily be trimmed as desired to allow a greater range of motion for an optical or surgical instrument within the body cavity. A valve/fulcrum within the tubular structure helps control the optical or surgical instruments. When tissue needs to be removed from the body cavity, the stem of the trocar may be expanded to allow passage of the tissue being removed, which stretches the incision. The insufflation gas is injected into the body cavity at a point other than through the trocar, which further optimizes intraoperative optics while minimizing tissue trauma.
