Abstract
An adjustable mold for forming spacer devices or parts thereof for the replacement of a joint prosthesis or part thereof, and the related kit for forming such spacer devices or parts thereof.
Claims17
A mold (1) for forming spacer devices (SD) or parts thereof for replacement of a joint prosthesis or of a part thereof, comprising:
- a main body (2) defining at least one molding cavity (MC);
- and
- adjusting means for adjusting (3) a height of said at least one molding cavity (MC), so as to enable a variation of the height of said at least one molding cavity (MC) or to carry out a controlled filling of the at least one molding cavity in such a way that said mold (1) allows forming at least two spacer devices (SD) with different heights or thicknesses in relation to each other,
- wherein said main body (2) comprises a base component (2a),
- wherein said adjusting means (3) comprises at least one auxiliary component or insert (3a, 3e, 3f) engageable or connectable with said base component (2a),
- wherein said at least one auxiliary component or insert (3a, 3e, 3f) is designed to define a bottom and/or a top of said at least one molding cavity (MC), said base component (2a) comprising one or more defining or delimiting sections (4) configured as steps extending from an inner wall of said at least one molding cavity to engage said at least one auxiliary component or insert and arranged to define or delimit a lateral surface or extension of said at least one molding cavity (MC), or
- wherein said at least one auxiliary component or insert (3e, 3f) is configured as a ring defining internally a surface that is cylindrical or stepped in staircase manner, said at least one auxiliary component or insert (3e, 3f) comprising one or more defining or delimiting sections (4) that define or delimit the lateral surface or extension of said at least one molding cavity (MC), said at least one molding cavity (MC) being defined by said at least one auxiliary component or insert (3e) and at a bottom by said base component (2a) or by said at least one auxiliary component or insert (3e, 3f).

- wherein said main body (2) delimits at one end (2c) a main opening (MO) for accessing the at least one molding cavity (MC), and wherein said main body (2) comprises at least one bottom (2d) opposite to the main opening (MO), and
- wherein said bottom (2d) of said main body is open so as to define a light or through opening (2e).
