  • Patent number: 11596748
    Abstract: A hybrid blunt cannula with puncture needle assembly provides an outer cannula member comprising a needle channel, an eye, a stopper member disposed at the second end of the cannula member, and an inner needle disposed inside the needle channel and coupled to buttons. The buttons follow a translation path between a static position and an insertion position. The static position enables the free end of inner needle to be proximal to the second end of the outer cannula member, and within the needle channel. The insertion position enables the free end of the inner needle to be proximal to second end of the outer cannula member and partially outside of the outer needle's channel. The free end of inner needle is operable to penetrate the stopper member while in insertion position for discharge of a liquid through the eye.
