  • Publication number: 20240138678
    Abstract: The present invention discloses a highly reliable implantable device of an implantable biological sensor. Before use, the fixed seat cannot move relative to the slidable seat, achieving reliable transportation. In use, the lower end face of the slidable seat is pressed against the skin; the lower end face of the first snap-fit protrusion squeezes the upper end face of the vertical snap-fit plate; the first snap-fit protrusion is gradually away from the support of the vertical snap-fit plate, whereby the inside vertical face of the vertical snap-fit plate pushes the first snap-fit protrusion inward, and the fixed seat moves downward relative to the slidable seat, achieving good controllability.

  • Patent number: 9421092
    Abstract: An intraocular lens injector cartridge assembly contains a pre-loaded lens and an integral lens-contacting plunger rod. Configured for removably mating with an injector handpiece, the cartridge assembly is suitable for use with either manual or automated injector systems. The injector cartridge assembly includes a tubular body having a longitudinal bore extending between a distal end and a proximal end, an IOL disposed within said longitudinal bore, and a lens-contacting plunger rod retained within said bore, between the IOL and the proximal end of the tubular body. The lens-contacting plunger rod is configured for translation along the longitudinal bore upon engagement by an injector rod introduced by the injector handpiece into the proximal end of the tubular body, so that the IOL is folded and ejected from the distal end of the tubular body by the translation of the lens-contacting plunger rod.
