  • Patent number: 9561046
    Abstract: The teachings herein provide an instrument comprising a forceps. The forceps comprise a hand piece; a tubular member connected to the hand piece; and a jaw assembly connected to the hand piece. The jaw assembly includes a first jaw element and a second jaw element. The first jaw element includes a gripping section and a flexing section. The flexing section includes an arcuate section. The second jaw element opposes the first jaw element and includes a gripping section. The tubular member is moveable onto the arcuate section of the first jaw element so that the flexing section of the first jaw element is flexed and the jaw assembly is moved into a closed position. The first jaw element, the second jaw element, or both include a stiffening spine so that the jaw assembly is substantially rigid in the closed position.

  • Publication number: 20160296274
    Abstract: A forceps including a gripping assembly. The gripping assembly includes an upper jaw and a lower jaw. The upper jaw includes a proximal end and a distal end. The upper jaw includes an upper tooth having an upper proximally facing canted tooth surface and an upper distally facing canted tooth surface. The lower jaw includes a proximal end and a distal end. The lower jaw includes a socket having a lower distally facing canted socket surface and a lower proximally facing socket surface. The upper jaw, the lower jaw or both are moveable so that the gripping assembly moves between an open position and a gripping position. In the gripping position, a gap is defined between the upper distally facing canted tooth surface and the lower proximally facing socket surface.

  • Publication number: 20150105821
    Abstract: A laparoscopic forceps comprising a handpiece including a distal end portion; a tubular member protruding from the distal end portion of the handpiece, the tubular member having a distal end, a pair of jaws having legs that are disposed within the tubular member and partially protruding from the distal end of the tubular member, the pair of jaws and the tubular member being movable relative to each other in a direction parallel to a longitudinal axis of the tubular member; wherein each of the pair of jaws has an arcuate section, and the pair of jaws are closable by advancing the tubular member over the arcuate section of the jaws; and an operable mechanism for creating relative motion between the pair of jaws and the tubular member along a direction parallel to the axis of the tubular member, wherein at the distal end portion of the tubular member there is a profile shape that is non-circular.

  • Publication number: 20140148804
    Abstract: Electrosurgical forceps that can provide improved hemostatis and tissue-cutting capabilities during surgical procedures. The electrosurgical forceps include opposing jaw members, each including first and second electrode members. The first and second electrodes included in the respective jaw members are disposed directly opposite one another, the first electrode members included in the respective jaw members are disposed diagonally opposite one another, and the second electrode members included in the respective jaw members are disposed diagonally opposite one another. A first high frequency (HF) electric power source is connectable across the first electrode members, and a second HF electric power source is connectable across the second electrode members, electrically isolating the first electrode members from the second electrode members, and allowing current to flow diagonally through the tissue between one or both of the first electrode members and the second electrode members.

  • Publication number: 20140135805
    Abstract: A forceps comprising: (a) a stylet comprising; (i) a hollow tube having a longitudinal axis; (ii) assemblies, that are extendable through the hollow tube, comprising; (1) support rods; (2) functional attachments at the end of the support rods; (b) a hand piece comprising; (i) housing structures defining a cavity that houses the stylet; (ii) actuating mechanisms, in communication with the stylet, comprising; (1) a bearing fitting located on the stylet; (2) a shuttle in communication with the bearing fitting, and constrained by a plurality of guide ridges so that the shuttle is movable along a longitudinal axis and restricted from rotational movement around the longitudinal axis; (3) a socket housed by the shuttle, the socket receiving the bearing fitting and being rotatable relative to the shuttle; and (4) levers in communication with the stylet that causes movement of the hollow tube and the assemblies are relative to each other.
