Abstract

The subject invention provides a suction retractor comprising a flexible continuous dam which forms a closed loop of any shape and which defines one or more inlet opening into an interior of the closed loop, so that suction can be applied into an interior of the continuous dam. The suction retractor may further comprise a suction tube defining a suction channel, the suction tube attached to or attachable to the continuous dam and when attached the suction channel continuous with the one or more inlet. The one or more inlet may open to a continuous channel extending throughout an interior of the closed loop. Preferably, the continuous dam is planar or substantially planar and comprises a first compacted configuration for insertion and a second open configuration for retraction. The suction retractor of the invention finds application in single incision and convention laparoscopic surgery.
