Definitions

  • the prosthesis according to the invention is comprised of two arms each with a length of some 5 mm. and which enclose between them an angle which is slightly larger than 90, and of a screw which lies in the plane of the arm axes.
  • the one arm is provided at the end thereof opposite to the other arm, with a fiat portion through which passes said screw.
  • said other arm has a thickness which is reduced towards that end opposite to the arm through which passes said screw.
  • the thickness of the screwbearing arm, adjacent said fiat portion is about equal to the screw length.
  • said screw is a self-tapping screw.
  • FIG. 1 is an elevation view of a prosthesis according to the invention.
  • FIG. 2 is a plan view of the prosthesis shown in FIG. 1.
  • the prosthesis shown in the figures comprises on the one hand, a plastic material body and, on the other hand, a metal screw.
  • the plastic material should not be attacked by the human organism liquids.
  • the material known under the trade name Teflon is particularly well suited.
  • the metal the screw is made of should also not deteriorate.
  • the metal known under the trade name Vitallium is also particularly well suited.
  • the body is comprised of two arms 1 and 2 the geometrical axes of which are designated by 3 and 4. Each one of the arms 1 and 2 has a length ranging about 5 mm.
  • the angle a enclosed between the axes 3 and 4 is slightly larger than and it lies for example in the range of to That end of the arm 2 opposite to the arm 1 is pierced by a screw 5.
  • Said screw is a self-tapping screw. It lies in .1 plane which is determined by the axes 3 and 4 of the arms 1 and 2.
  • the screw 5 is retained by a fiat portion 6 which comprises the end of the arm 2.
  • the arm 2 has a thickness ranging about the screw length, which is approximately 3 mm.
  • the height of the flat portion 6 is about 0.4 mm.
  • the thickness of the arm 1 is reduced towards that end 7 opposite the arm 2. At the end 7, the thickness of the arm 1 is about 0.6 mm.
  • the screw 5 is used for attaching the end of the arm 2 to the hammer while the end 7 of the arm 1 is to bear on the stirrup-bone, preferably on the plate thereof, or it contacts directly the internal ear liquids.
  • the plastic material body may be replaced by a body of some other material, for instance a Vitallium body.
  • a middle ear prosthesis made of a material suitable for implanting in the human body, which is comprised of two connected arms having their axes lying in a common plane, each arm having a length of some 5 mm. which encloses between them an angle which is slightly larger than 90, and a screw attached to the free end of one arm which lies in said plane of the arm axes.
