Abstract: A retractor (1) that is meant to be placed in a wound (7) to hold this open during a surgical operation, comprising a shackle of a plastic material pervious for X-ray radiation. The shackle has to resilient legs (2a, 2b), that in a resilient way can be brought towards each other from a starting position in order to be inserted into the wound (7) and thereafter through resilient return towards the starting position be brought to contact with the edges of the wound (7) and thereby holding these apart and in a self-holding way fasten the retractor (1) in the wound (7).
Abstract: A retractor for placement in a wound to hold the wound open during a surgical procedure comprising a closed loop formed of a plastic material permeable to X-ray radiation, said closed loop having two opposite members that can be brought together from a starting position to enable insertion of wound edge gripping elements of the retractor into the wound and thereafter through resilience return towards the starting position and brought in contact with the edges of the wound and hold the wound edges apart and in a self-holding way retain the retractor in the wound.
