Abstract
Instrument (1) designed, in particular, to permit the extraction of vein sections such as, for example, varices, including a two-piece supple cable (2) that is flexible and strong, both ends of which support a bullet shaped member (3). The cable (2) has a diameter substantially smaller than that of the vein to be extracted, and a length corresponding substantially to at least the length of the vein. The two cables are connected end to end by complementary connecting pieces. An olive-shaped member holds the connecting pieces within an internal bore. The bullet shaped members have a radial orifice for receiving a thread to assist in endo-stripping of the vein section.
Claims11
An instrument for extraction of a vein section comprising:
- a first flexible cable having at one end a bullet-shaped member and at an opposite end a connecting piece, said bullet-shaped member having a radial orifice extending therethrough;
- a second flexible cable having a complementary connecting piece at one end and a bullet-shaped member at the other end, said complementary connecting piece detachably connected to said connecting piece of said first cable, said first and second cables having a diameter substantially less than a diameter of the vein section, said first and second cables having a length at least as long as the vein section;
- and
- an olive-shaped member of a substantially frustoconical shape, said olive-shaped member having an interior bore detachably receiving to the connecting pieces of said first and second cables.
