  • Publication number: 20130060250
    Abstract: A forceps includes an end effector assembly having first and second jaw members. Each jaw member includes an elongated proximal segment and a distal segment. The distal segments are configured to grasp tissue therebetween. The jaw members are biased towards a spaced-apart position relative to one another. A sliding unit is disposed about the first and second jaw members and is slidable relative to the jaw members between a first position, wherein the sliding unit is disposed about the elongated proximal segments of the jaw members, and a second position, wherein the sliding unit is disposed about the distal segments of the jaw members. The sliding unit is configured to transition the jaw members against the bias from the spaced-apart position to an approximated position for grasping tissue therebetween upon sliding of the sliding unit from the first position to the second position.

  • Publication number: 20120022584
    Abstract: A jaw movement mechanism for surgical tools has improved mechanical efficiency and other advantages. The jaw movement mechanism controls the orientation and position of a movable jaw relative to a fixed jaw through a range of movement of the movable jaw. The jaws maintain a parallel orientation throughout a portion of the range of movement of the movable jaw. The jaws maintain an angular relationship throughout a portion of the range of movement of the movable jaw.

  • Patent number: 8092488
    Abstract: An improved bone retractor tool includes a pair of arms pivotably connected to one in a pliers-like configuration and a pair of tissue engagement plates each having forward and rearward portions, each of the pair of tissue engagement plates mounted on the upper end of one of the pair of arms and extending generally parallel with one another when the pair of arms are in closed position. Forward bone engagement spikes are mounted on and extend forwards from the forward portions of the tissue engagement plates. A releasable securement mechanism is mounted on the pair of arms for releasably retaining the pair of arms in a selected position relative to one another, and a tensioning device is mounted on the pair of arms for tensioning the lower ends away from one another thereby forcing the pair of tissue engagement plates towards one another upon the securement mechanism being released.

  • Publication number: 20110313449
    Abstract: A surgical end effector includes a clevis having a first end to be supported by an elongated tube-like member and two jaws, each having a pivot portion and a working portion. The pivot portions are rotatably coupled to the clevis by two spaced apart pivots. The working portions may include a cutting edge that provide a shearing action as the first and second jaws rotate about their respective pivots. The pivot portion and the working portion of each jaw may be on opposite sides of a bisecting plane. A flexible cable or wire may be coupled to each jaw and extend through a guide way in the other jaw, between the first and second pivots, and through the first end of the clevis. One or more springs may urge the working portions together. A rocking pin pivotally supported by the clevis may constrain the jaws to have opposite motions.
