摘要：
A port for minimal access surgery, such as endoscopic or laparoscopic surgery, via an incision in a patient is described together with methods of use of such a port. The port 2 comprises a substantially cylindrical sleeve 8 formed of a flexible membrane material and has a first, open end and a second, closed end 10, a first resilient ring arrangement 4 at the open end, and a second resilient ring arrangement 6 around said sleeve 8 and located between the first resilient ring arrangement 4 and the closed end 10, thus functioning as both a wound retractor/port and a seal for the contamination-resistant introduction of surgical instruments. In use, the sleeve is inverted (passing the second ring through the first ring, see figure 2a) and then inserted in an incision in the normal way, rolling material around the outer ring to contact around the incision (figure 2b).
