Abstract

The invention relates to a configuration for forming a polymer layer on a base metal surface of an artificial joint composite. The purpose is successful miniaturization while accurately controlling UV ray irradiation intensity such that a polymer layer of uniform thickness can be formed with no or minimal UV ray effect on workers or facilities. A film-producing device body (20) forms a polymer layer (12) on an inside surface (11e) of a base metal (11) of an artificial joint composite by light-induced graft polymerization. The film-producing device body (20) comprises multiple UV ray LED elements (60) and a work holder (24). A solution (23) containing a polymer monomer is brought into contact with the inside surface 11e of the base metal (11) on the work holder (24). The multiple UV ray LED elements (60) radiate UV rays over a region that is broader than the region irradiated by a single UV ray LED element (60).

Description

technical field [0001] The present invention relates to a film manufacturing device used for manufacturing an artificial joint unit, and a method for manufacturing an artificial joint unit. Background technique [0002] For the purpose of improving the wear resistance of artificial joints, attempts have been made to form sliding surfaces of artificial joint components with coatings. As a method for forming such a coating layer, a method of forming a polymer layer by photograft polymerization on the surface of a base material which is a main part of an artificial joint component is known (for example, refer to Patent Document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2011-197544 (paragraph [0037]) [0006] Patent Document 1 discloses a structure in which a photograft polymerization reaction occurs by irradiating light to a solution of a monomer containing a polymer in a state where the solution is ...
