摘要： A clip applying apparatus is provided which includes a jaw mechanism supported within and extending from the distal end of a body portion of the apparatus. The jaw mechanism includes a proximal body portion, first and second shank members and first and second jaw members. The first and second shank members extend distally from the proximal body portion of the jaw mechanism. The first and second jaw members are supported on the distal end of the first and second shank members and are configured to receive a ligation clip therebetween. In a particularly useful embodiment, each jaw is curved upwardly towards its distal end along the longitudinal axis of the body portion and has a radius of curvature “r” of between about 0.5 inch and about 0.9 inch. In a particularly useful embodiment, r is about 0.7 inch. A method for accessing and ligating tissue is also disclosed wherein the clip applying apparatus described above is positioned adjacent tissue to be ligated and the jaws are moved between the tissue to be ligated and surrounding tissue to manipulate and/or reposition the tissue. The jaw mechanism can be rotated to position the tissue to be ligated between the first and second jaws to ligate and/or crimp a ligation clip about the tissue to be ligated.

摘要： A surgical fastening apparatus includes a handle, an elongated member extending distally from the handle and a fastener applier and anvil head disposed at the distal end of the elongated member. The elongated member defines a distal offset end portion upon which the fastener applier and the anvil head are mounted. The offset end portion is angularly oriented with respect to the axis of the instrument at a predetermined fixed angle (e.g., either 45°, 60° and 75° relative to the axis of the instrument) thereby positioning the fastener applier and the anvil head at the fixed angle. This feature facilitates positioning of the tissue with respect to the instrument and enhances visual access to the tissue when appropriately disposed within the fastener applier and the anvil head. Various mechanisms for effectuating the clamping of the tissue between the fastener holder and anvil, and the firing of the instrument are disclosed.

摘要： A surgical clip applying apparatus is disclosed which has a handle portion, a body extending distally from the handle portion defining a longitudinal axis and a number of surgical clips disposed within the body. The apparatus has a movable member biased in the housing adjacent the wedge plate. An actuator longitudinally advances the wedge plate a predetermined distance to a distal most position. The wedge plate has an end being disposed between first and second jaw portions at the distal most position. The wedge plate end is configured to maintain the jaw assembly in the spaced apart position during loading of the surgical clip and the wedge plate end reduces torque and external forces on the jaw assembly during the loading. The movable member holds the wedge plate in the distal most position during the loading and the movable member is deflected at a conclusion of the loading. The movable member releases the wedge plate upon deflection. The movable member allows a longitudinal proximal retraction of the wedge plate from the distal most position.

摘要： An apparatus for application of surgical clips to body tissue includes an actuator at least partially disposed within a body and longitudinally movable in response to actuation of a handle portion. The apparatus includes a jaw closure member positioned adjacent the first and second jaw portions to move the jaw portions to the approximated position and a rack having ratchet teeth connected to the actuator. The apparatus includes a pawl engaging a series of ratchet teeth and capable of preventing an inadvertent return of the actuator before full actuation of the apparatus. A clip pusher incrementally moves distally each time a clip is released from the apparatus. When the clip pusher reaches a predetermined distal point in a clip carrying channel, a feed bar is deflected to a second position to prevent retraction but not advancement of the actuator and thereby manipulates the pawl to engage the ratchet teeth.

摘要： A specimen removal apparatus includes a pouch assembly fabricated from a flexible membrane, a pouch support, a drawstring having a knot and forming a noose disposed circumferentially around a mouth of the pouch assembly, an endoscopic tubular portion, and a drive rod. The pouch assembly includes a plurality of circumferentially disposed guide members advantageously circumferentially spaced apart to define gaps therebetween. The guide members are disposed in a circumferential pathway proximal to the mouth of the pouch assembly. When the drawstring is pulled, the knot is stopped at an end of a guide member and the noose is closed, thereby closing the mouth of the pouch assembly. The pouch assembly is detachable from the apparatus.
