摘要:
1. A method of testing ceramic spherical head (3) for a hip joint prosthesis having a receiving space (8) with a conical side surface taper angle γ and conical inlet (7) while checking for some portions of the receiving volume (8) is pressure, characterized in that the radial force directed perpendicular to the longitudinal axis of the spherical head (3) has an effect only on the conical entrance region (7) .2. The method of claim 1, characterized in that for checking the receiving space (8) is pressed into the conical sleeve (1) with the angle α of the cone, the cone opening angle α greater than the angle of taper γ.3 solution. A method according to claim 2, characterized in that the α of the cone angle is selected in the range of 7 to 30 °, preferably 18 °, and the difference between the opening angle of the clamping cone γ and the cone angle α must be selected between a minimum value of 2 ° and a maximum. - 25 ° .4. The method of claim 2, characterized in that the conical surface forming the sleeve (1) is closed, and consists preferably of a copper alloy, preferably latuni.5. A method according to any of pp 2-4, wherein the tapered punch (2) with a common hub (1) an angle α of the cone is pressed by the sleeve axis (1) with a force F.6. The method of claim 5, characterized in that the friction between the sleeve (1) and the punch (2) is lower than the friction between the sleeve (1) and the spherical head (3) .7. The method of claim 5, characterized in that the punch (2) consists of steel, preferably hardened with poverhnostyu.8. A method according to any of pp 2-4, wherein the inner surface inspection for the sleeve (1) is subjected to hydraulic davleniyu.9. Device for implementing the method according to one of ppt 1-8, characterized in that the apparatus incl1. Способ проверки керамических шаровидных головок (3) для протезов тазобедренного сустава, имеющих приемное пространство (8) с конической боковой поверхностью с углом зажимного конуса γ и коническим входо
