Suction retractor

摘要

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.

主权项

1. A suction retractor comprising:
a flexible continuous dam which forms a closed loop of any shape and which defines one or more inlet, the one or more inlet communicating with a channel which extends about the closed loop, the channel configured to introduce suction into an interior area surrounded and defined by an inner perimeter of the closed loop, a guard disposed interiorly of the inner perimeter of the closed loop at least covering or partially covering the one or more inlet so that suction can be applied through the one or more inlet and into the interior area of the continuous dam, the closed loop defining opposing first and second faces extending about the interior area, the dam being sufficiently flexible so that the first and second faces may each bend while the first and second faces simultaneously conformationally engage in apposition adjacent body tissue in face-to-face sealing engagement, wherein, the one or more inlet being configured to introduce sufficient suction that, with the first and second faces being in face-to-face sealing engagement with adjacent body tissue, the adjacent body tissue is drawn towards the interior area with the guard preventing the adjacent body tissue from being drawn into the one or more inlet.
