  • 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: 10390852
    Abstract: A surgical device includes an elongated needle body defining an interior lumen extending longitudinally therethrough, having a sharpened distal tip portion. The device further includes an assembly operatively associated with the interior lumen of the needle body. The assembly includes a shaft having an outer surface profile corresponding to an inner surface of the interior lumen of the needle body and a pair of arms extending distally from the shaft. The pair of arms are biased radially outward from the longitudinal axis of the shaft, and each of the pair of arms having a blunt front surface, wherein one of the arms is in a fixed axial alignment with the sharpened distal tip portion of the needle body such that the arms act as an obturator relative to the sharpened distal tip portion of the needle body to guard the needle body from causing accidental needle tip trauma.

  • Publication number: 20180132838
    Abstract: A surgical instrument assembly including a housing containing a specimen retrieval bag and pliable spring, a distal end including a non-blunt tip and a deployment mechanism. The specimen retrieval bag is moved from the stowed position within a hollow housing to a deployed position by sliding a rod from a retracted position within the hollow housing to an extended position that projects at least partially out of the hollow housing. Two portions of a flexible support ring unfold under spring bias from a folding position as the rod enters the extended position to open a mouth of the specimen retrieval bag. The distal end of the assembly has a non-blunt tip which is shaped to puncture human skin. The deployment mechanism may include a rod, slide, grip or handle. The specimen retrieval bag may be comprised of more than one material.
