Abstract
A trocar is provided for providing access to body cavities during minimally invasive surgeries. The trocar possesses an elongate body formed of an outer tube and an inner tube, both of which are threaded. Rotating the outer tube about the inner tube permits adjustment of the length of the elongate body of the trocar. A locking collar on the trocar is used to maintain the elongate body at the desired length.
