DEVICE FOR CLIPPING PERFORATED VEINS OF LOWER EXTREMITIES Russian patent published in 2000 - IPC

FIELD: medical engineering. SUBSTANCE: device has hollow tube having rod movable in axial direction mounted inside the tube. Unit having a spring is available for holding clips and adjusting rod movement distance. Distal portion of the hollow tube of 3 mm diameter is curved at an angle of 20-25 deg at a distance equal to 1/3 of its length when starting from the working end. Two longitudinal diametrically disposed slots and edge are formed along the cone length. The edge is sharpened to form cutting edge for doing puncture. End piece is mounted on the rod tip as two cones of opposite orientation coinciding with their bases. Slots are produced on the distal conic part of the hollow tube equal in size and coinciding with slots on conic portion of the hollow tube. Opening is made on the lateral surface of the hollow tube for introducing a clip and then placing it in the end piece slots coinciding with the opening. EFFECT: reduced traumatic consequences due to operation; improved cosmetic quality. 4 cl, 1 dwg
