Abstract: A method for creating a model of a patient-specific instrumentation jig for implant revision includes obtaining an image of part of a patient bone and of an implanted implant on the bone. A reference anchor surface(s) is identified on the bone from the image, to receive a guide reference. An implant abutment surface is determined on the implanted implant. A virtual reference jig model is generated using the identified reference anchor surface and the determined implant abutment surface, and has a contact surface corresponding to the determined implant abutment surface for complementary connection with the determined implant abutment surface, a guide interfacing portion to guide a planting of the guide reference in the reference anchor surface, and a patient-specific geometry between the contact surface and the guide interfacing portion, to position and/or orient the guide interfacing portion relative to the reference anchor surface.

Abstract: The present invention relates to a method for the production of polyamide 6 with low extract content and a device for it. Here, a melt of non-extracted polyamide 6 is cleaned from monomer and oligomers in a degasification device in vacuum, wherein the vapor being withdrawn from the degasification device by the vacuum generation device is cleaned from monomer, oligomers and optionally water at first in a direct condenser which is operated with liquid ?-caprolactam and subsequently in a pre-separator which is cooled with a coolant, before it reaches the vacuum generation device. A particularly preferable variant of the method envisages the usage of the melt of polyamide 6 with low extract content so prepared in a direct process of spinning into textile fibers and/or filaments.
