Abstract
An improved trocar is provided which includes converters for adapting to different size surgical instruments while maintaining sealing. The invention also includes an improved trocar tube body seal design which accepts and accommodates surgical tool angulation while still maintaining sealing. Still further, the invention provides a trocar obturator with a snap-fit joint which permits the forward portion of the obturator to be detached from the trocar body and separately used with the trocar tube subassembly. With this option, a latch mechanism is configured opposite to a converter to retain the obturator fixed with the trocar tube subassembly.
