Crimping - pliers for stapes - prostheses

摘要

A otological crimping - pliers (1) for fastening a first coupling element (11) of a ossicular prosthesis (10) on a incus, wherein the prosthesis an elongated prosthesis body (13) with a second coupling element has a (12) at its opposite end, and wherein the crimping - pliers a jaw member with two pivotable relative to each other, asymmetrically constructed limbs (2a, 2b), which enclose between them a round bulge, which is provided in the form and size to the outer contour of the incus is tuned, is characterized in that one of the two legs of a transversely extending, continuous notförmige recess (3a) which, in the plane spanned by the legs and is so dimensioned that it is the to the first coupling element has a directly adjoining region of the prosthesis body can lead to receive and mechanically. In this way, a satisfactory crimping the stapes - prosthesis to be implanted made possible, with a permanently reliable seat and a damage to free coupling at the incus - fabric as well as an acoustically optimum function of the coupled ossicular prosthesis are ensured.
