<p>An apparatus for allowing simultaneous use of at least two surgical instruments through a single incision. The apparatus comprises a first part having a proximal end, a distal end, an inner surface and an outer surface. The outer surface is for engaging an incision and holding the incision in an open position and the inner surface defines a passageway through the first part from the proximal to the distal ends. The apparatus also comprises a second part attached to the proximal end of the first part for sealing the proximal end of the first part and comprising at least two ports for receiving a surgical instrument, and wherein at least one of the ports comprises a ball joint to allow articulation of the port relative to the second part. The use of a ball joint allows the orientation of the port and the surgical instrument within it to be moved easily relative to the apparatus.</p> |
