The present invention relates to a wound retractor, and more particularly to a wound retractor which is inserted into the cut portion of the abdomen of the patient to open the cut portion and to prevent extractions from coming in contact with the cut portion and aims to facilitate winding a cylindrical tube around the upper ring of the wound retractor with less force, comprising: a cylindrical tube which is a flexible elastic body and extends in a cylindrical shape; a lower ring which is a ring-shaped flexible elastic body and connected and sealed along the lower circumference of the cylindrical tube; and an upper ring which has a first ring and/or a second ring which are closely attached to be connected and sealed around the upper circumference of the cylindrical tube, the first ring and/or the second ring having a ring-shaped rigid member inserted inside and a coating member surrounding the outer circumference of the rigid member, wherein silicon oil is filled between the outer circumference of the rigid members of the first ring and/or the second ring and the inner circumference of the coating members thereof, and a connection part is formed to integrally connect the coating members to the portion where the first ring and/or the second ring are closely attached. |
