  • Patent number: 11109875
    Abstract: A minimally invasive surgical assembly broadly includes an outer hollow needle which has an outer diameter of 3.0 mm or smaller, and a coaxial surgical instrument having a shaft which extends through the outer hollow needle. The coaxial surgical instrument includes end effectors at the end of the shaft which are biased to an open position such that when the end effectors of the surgical instrument extended out of the needle they open, and they are closed by relative movement of the needle over them. The assembly preferably includes a first fixing element which is used to fix the relative location of the surgical instrument and the needle. The assembly also preferably includes a second fixing element which moves relative to the needle and is located on the outside thereof and which is used to fix the relative location of the needle to the patient.

  • Patent number: 10722297
    Abstract: A minimally invasive surgical assembly broadly includes an outer hollow needle which has an outer diameter, a longitudinal axis, and a sharp distal end. An insulating member extends through the hollow needle and is movable relative to the hollow needle. An elongated member extends through the insulating member and is movable relative to both the insulating member and the hollow needle. A resilient wire projects from the elongated member and is retractable within and extendable outside of the insulating member and the hollow needle. The insulating member, elongated member, and resilient wire are movable relative to the needle using first and second moving means whereby the surgical assembly assumes various configurations having different operational functions.

  • Patent number: 9486238
    Abstract: A minimally invasive surgical assembly broadly includes an outer tube which has an outer diameter of 3.0 mm or smaller, and a coaxial surgical instrument having a shaft which extends through the outer hollow tube. The coaxial surgical instrument includes end effectors at the end of the shaft. The end effectors include spring arms and wire frame clamp elements defining fenestrations. The spring arms are biased to an open position such that when the end effectors of the surgical instrument extend out of the outer tube they open, and they are closed by relative movement of the outer tube over them. The wire frame clamp elements are biased to an open position such that when they extend out of the outer tube they open and they are closed by relative movement of the outer tube over them.

  • Publication number: 20150148800
    Abstract: A minimally invasive surgical assembly broadly includes an outer hollow needle which has an outer diameter, a longitudinal axis, and a sharp distal end. An insulating member extends through the hollow needle and is movable relative to the hollow needle. An elongated member extends through the insulating member and is movable relative to both the insulating member and the hollow needle. A resilient wire projects from the elongated member and is retractable within and extendable outside of the insulating member and the hollow needle. The insulating member, elongated member, and resilient wire are movable relative to the needle using first and second moving means whereby the surgical assembly assumes various configurations having different operational functions.
