Spacer mould and method for producing hip spacers

摘要

SPACER MOULD AND METHOD FOR PRODUCING HIP SPACERS The invention relates to a spacer mould for producing a hip spacer comprising a base element (1), in which a hollow mould is provided as negative image of one side of a femoral stem of the spacer to be generated, whereby a recess connected to the hollow mould is arranged on the proximal end of the hollow mould in the base element; a semi-spherical insert (2) comprising a femoral head mould as negative image of one side of a femoral head of the spacer to be generated, whereby the semi-spherical insert (2) is to be arranged in the recess in the base element (1); an adapter insert (3) that is designed as a hollow body that is open on two sides and that is or can be arranged in the recess of the base element (1) between the semi-spherical insert (2) and the hollow mould such that the recess exerts a pressure onto the adapter insert (3) and the semi spherical insert (2); a punch (4) that comprises a punch hollow mould in the form of the negative image of the remaining femoral stem and that is arranged on or can be pressed onto the top side of the base element (1); whereby a cutting edge bounding the connection of the hollow mould of the base element (1) to the punch hollow mould of the punch (4) is arranged on the edge of the hollow mould of the base element (1) and/or on the edge of the punch hollow mould of the punch (4), and a cutting edge bounding the connection of the femoral head mould to the opening of the hollow body of the adapter insert (3) is arranged on the edge of the femoral head mould and/or on the edge of said opening of the hollow body of the adapter insert (3) to the femoral head mould. The invention also relates to a method for producing a hip spacer and to a hip spacer produced with a method of this type and/or to a spacer mould of this type. Figure 1
