The invention relates to surgical forceps used for the extraction of varicose veins and having: —a body with an articulation plate (4) and an elongate tubular sheath (1); —two manoeuvring branches (2a, 2b) mounted on the articulation plate (4) and movable relative to each other between an open position and a closed position, each of these branches (2a, 2b) having a ring (5a, 5b) for the introduction of a finger; —a gripper (3) mounted at the distal end of the tubular sheath (1) and having two jaws (7a, 7b) mounted movably relative to each other about an axis A between an open position and a gripping position, the inner faces of said jaws (7a, 7b) being toothed in order to hold the varicose veins; and—means for transmitting the movement of the manoeuvring branches (2a, 2b) to the jaws (7a, 7b), via the tubular sheath (1), said means being designed to move the jaws (7a, 7b) to their gripping position when the manoeuvring branches (2a, 2b) are closed together. |

1. A method of removing varicose veins with surgical forceps, the forceps comprising:
a body with an articulation plate and an elongate tubular sheath; a gripper mounted at a distal end of the tubular sheath having two jaws mounted movably relative to each other around a pivot axis between an open position and a gripping position, the jaws having toothed inner faces; two maneuvering branches mounted on the articulation plate and movable relative to each other between an open position and a closed position, each of the branches having a ring for the insertion of a finger, the rings being spaced apart by a distance of at least 1 cm relative to a working plane of the forceps, orthogonal to the pivot axis and in which the jaws extend; a linkage for transmitting the movement of the maneuvering branches to the jaws, via the tubular sheath, said linkage formed to move the jaws to the gripping position when the maneuvering branches are moved towards one another;wherein the method comprises:
inserting a finger in each ring; introducing the surgical forceps into a patient's skin in a plane substantially parallel to a surface of the skin such that the working plane is located between the rings and the surface of the skin, wherein the rings are offset from the surface of the skin; and moving the maneuvering branches towards one another to move the jaws to the gripping position to grip the varicose veins. |
