  • Publication number: 20230103231
    Abstract: The invention provide a method for producing coated silicone hydrogel contact lenses in a cost-effective and environmentally friendly manner. The method is free of lens extraction step and comprises: curing thermally or actinically in a lens mold a polymerizable composition that comprises at least one hydrophilized polysiloxane vinylic crosslinker, hydroxyethyl methacrylate, C1-C2 alkoxyethyl (meth)acrylate, at least one free-radical initiator, and at least one solvent selected from the group consisting of water, propylene glycol, and/or a low-molecular weight polyethyleneglycol; and heating the cast-molded silicone hydrogel contact lens in an aqueous coating solution to form a coated silicone hydrogel contact lens comprising a bulk silicone hydrogel material and a layer of a crosslinked hydrophilic polymeric material that is covalently attached onto the bulk silicone hydrogel material. Resultant contact lenses are optically clear and wettable and have a relatively high oxygen permeability.

  • Publication number: 20220240765
    Abstract: An endoscope forceps elevator. The bottom end of the endoscope forceps elevator communicates with an instrument channel and is provided with a hinge part that is hinged to a distal end base, and the top end thereof is provided with a positioning bayonet; and a guiding groove is formed between the instrument channel and the positioning bayonet. Before the endoscope forceps elevator being lifted, an instrument to be positioned may be guided into the positioning bayonet by the guiding groove and be laterally spaced and positioned. In the endoscope forceps elevator, the instrument to be positioned may be directly positioned by the positioning bayonet, the instrument to be positioned, such as a catheter or guide wire, may be precisely and effectively positioned during the process of lifting of the forceps elevator and during a surgery. Also disclosed are a corresponding endoscope distal end and duedenoscopy system.
