| 摘要 |
The invention relates to an enucleation ball made of a ceramic material. The ball comprises a porous inner sphere (10), which supports a perforated outer sphere (20) by means of spacers (30) connecting the inner sphere to the outer sphere. The invention also relates to a method for manufacturing such a ball. The method is characterised in that, on the basis of the geometrical definition of the ball and the various elements thereof - inner sphere (10), outer sphere (20), spacers (30), etc. -, the geometrical shape of the ball is cut into parallel slices which can then be used to manufacture the ball following a stereolithographic method. |
