Abstract

FIELD: medicine. SUBSTANCE: saphenoextractor has spiral-shaped pipe-conductor 1, string 2, olive 3 with cutting edge 4, collet 5 and nut 6, handle 7 provided with collet 8 and nut 9, protection caps 10. Pipe-conductor 1 is introduced into vein 12 to be extracted till achieving end point of vein to be removed. Then string 2 is introduced into pipe 1. Olive 3 is mounted at one end of the string, and handle 7 is mounted at the other end. When applying uniform force to pipe-conductor 1, vein is invaginated till getting preset resistance. Then in the same manner force is applied to olive 3 through string 2 across handle 7 to separate vein 12 from adjacent tissues by means of cutting edge 4. When applying force once more to pipe 1, cut corrugated segment of vein which has to be invaginated. After that the sequent section of vein has to be cut away. Alternative forces are applied to pipe 1 and handle 7 till vein 12 is removed completely from under skin 11. EFFECT: improved efficiency of treatment.

Claims

The invention relates to medicine, in particular to vascular surgery, and can be used in surgical treatment of varicose veins of the lower extremities. The safenoextractor consists of a spiral conductor tube 1, string 2, olive 3 with a cutting edge 4, collet 5 and nut 6, handles 7 with a collet 8 and nut 9, protective caps 10. A conduit 1 is inserted into the vein 12 to be removed to the end point the vein to be removed, then a string 2 is inserted into the tube 1, an olive 3 is placed on one end of the string, on the other handle 7. Applying uniform force to the conductor tube 1, the veins are invaginated until the specified resistance appears. Then, in the same way, the handle 7 exerts a force through the string 2 to the olive 3, separating the vein 12 from the adjacent tissues by means of the cutting edge 4. Again, applying force to the tube 1, the cut corrugated segment of the vein is invaginated, after which the next section of the vein is cut. An alternating force is applied to the tube 1 and handle 7 until the veins 12 are completely removed from under the skin 11.
