摘要:
A retractor for ophthalmic procedures and other uses is disclosed. The retractor is a U-shaped body formed by two arms and a live hinge, with a retracting means at the distal end of each arm. The retracting means includes a tongue blade for insertion under an eyelid, a deflector for retracting the eyelid, and two ball-tipped posts that extend away from the tongue blade and prevent eyelid or eyelashes from obscuring the window opened up by the retractor. The hinge is also an adjustable biasing spring that biases the distal ends of the arms to an open position. Anti-torque arches are provided on the outer wall of the body. A brace may be provided on the retractor, to fix the device to a desired position.
