Abstract
A method of manufacturing an orthopaedic surgical instrument comprising the steps of forming a generally planar shim having a predetermined shape; creating a plurality of holes or slots in the plane of the shim; temporarily shielding said holes or slots. from a plastic molding process; overmolding said shim with a plastic substrate using said plastic molding process; and creating a cutting surface at each of said holes or slots.
Claims21
A method of manufacturing an orthopaedic surgical instrument comprising the steps of:
- forming a generally planar shim having a predetermined shape;
- creating a plurality of holes or slots in the plane of the shim;
- bending said shim into a non-planar shape after said step of forming a generally planar shim and said step of creating a plurality of holes or slots;
- temporarily shielding said holes or slots from a plastic moulding process;
- overmolding said shim with a plastic substrate using said plastic moulding process;
- and
- creating a cutting surface at each of said holes or slots.
A method of manufacturing an orthopaedic surgical instrument comprising the steps of:
- forming a generally planar shim with a plurality of holes or slots and a predetermined shape;
- bending said generally planar shim into a generally hemispherical shape to form a non-planar shim after said forming step;
- temporarily shielding at least selected ones of said holes or slots of said non-planar shim from a plastic moulding process;
- overmolding said non-planar shim with a plastic substrate using said plastic moulding process;
- and
- creating a cutting surface at said holes or slots corresponding to said holes or slots of said step of temporarily shielding at least selected ones of said holes or slots;
- wherein said orthopaedic surgical instrument comprises an acetabular reamer cup.
A method of manufacturing an orthopaedic surgical instrument comprising the steps of:
- forming a generally planar shim with multiple outwardly extending limbs and a plurality of holes or slots;
- bending said generally planar shim into a non-planar shape to form a non-planar shim after said forming step;
- temporarily shielding at least selected ones of said holes or slots of said non-planar shim from a plastic moulding process;
- overmolding said non-planar shim with a plastic substrate using said plastic moulding process;
- and
- creating a cutting surface at said holes or slots corresponding to said holes or slots of said step of temporarily shielding at least selected ones of said holes or slots.
