ABSTRACT:
A surgical reamer, intended in particular for the shaping of the cotyloid cavity in the event of a replacement of a hip joint by total prosthesis. It is in the form of a hollow body of rotation equipped with fixing means (3, 4) for attachment to a reamer spindle in order to be driven in rotation. The hollow body (1) is supported by a bar (2) whose axis coincides at least approximately with the axis of rotation of the reamer and it extends essentially on one side of a plane containing the axis of the bar (2), at least part of the length of the rim of the hollow body forming a cutting edge (5). Such a reamer makes it possible to shape accurately a cavity of hemispherical or other shape, according to the shape of the hollow body.
