The anchor comprises a first main body (11) of a generally cylindrical shape having a front portion (1) for facing a body member to be treated, a rear portion (2), and a longitudinal axis (3). There is a curved surface (4), a central through-going bore (19) extending from the front portion (1) to the rear portion (2), and a longitudinal slit (12) which opens at the front portion (1) and at the curved surface (4) and is closed at the rear portion (2). It has a second conical body (14) having a smaller base (15), a larger base (16), a curved surface (17) and a longitudinal axis (13). The second conical body (14) is coaxially introducible with its smaller base (15) into the slit (12) thereby causing expansion of the first main body (11), the second conical body (14) being provided with a through-hole (6) running transversely to the longitudinal axis (13). There are two channels (7) positioned on the curved surface (17) of the second conical body (14) and extending from the orifices (18) of the through-hole (6) to the smaller base (15). |
