A surgical instrument is provided for use in endoscopic or laparoscopic procedures. The instrument includes a handle portion, an endoscopic portion extending from the handle portion, an articulating section pivotably connected to a distal end portion of the endoscopic portion, and a retractor assembly operatively associated with the articulating section. Structure is provided for manipulating the articulating section relative to the longitudinal axis of the endoscopic portion within an angular degree of rotation. An injection port may also be provided to deliver fluids through the endoscopic portion to the operative site.

Articulating endoscopic surgical apparatus

A surgical instrument is provided for use in endoscopic or laparoscopic surgery. The instrument includes a handle portion and an endoscopic portion. The endoscopic portion has an elongated tubular section having opposed proximal and distal ends, the proximal end of which extends from the handle portion, and an articulating section which is pivotally connected to the tubular section adjacent the distal end thereof. Tool means depend from the articulating section and a linkage mechanism is associated with the endoscopic portion for pivoting the articulating section relative to the longitudinal axis of the tubular section, within a 90.degree. sector of rotation. In addition, the instrument includes means for rotating the endoscopic portion about its longitudinal axis.

A surgical instrument is provided for performing a variety of endoscopic or laproscopic procures. The instrument includes a handle assembly, a tubular body extending from the handle assembly and defining a longitudinal axis, a tool assembly associated with a distal end of the tubular body including a tool base and tool members, a first mechanism for effectuating remote articulation of the tool assembly with respect to the longitudinal axis of the tubular body, a second mechanism for effectuating remote rotation of the tool assembly about the longitudinal axis of the tubular body, and a third mechanism for effectuating remote rotation of the tool members relative to the tool base.

Surgical apparatus having an increased range of operability

An endoscopic surgical instrument having a handle assembly, a body portion, and a tool mechanism in which a pivoting handle pivots about a stationary handle to open and close the tool mechanism. The instrument includes a rotatable body portion, in which a rotation knob is provided on the instrument at the stationary handle so that the user may rotate the body portion, and consequently the tool mechanism, using a single hand. Furthermore, an electrocautery connection is provided which is positioned out of the line of sight of the surgeon, so that the surgeon may have an unobstructed view to the surgical site. The pivoting handle is provided with a rotatable connection point for connecting the slidable rod member to essentially eliminate radial deflection of the rod within the outer tube during opening and closing of the handles. The tool mechanism may include grasping jaws having rounded, interdigitating teeth for grasping and securely holding tissue or organs for removal through a cannula.

Endoscopic surgical instrument

A surgical instrument is provided for use in endoscopic or laparoscopic procedures. The instrument includes a handle portion, an endoscopic portion extending from the handle portion, an articulating section pivotably connected to a distal end of the endoscopic portion, and a retractor assembly operatively associated with the articulating section. Structure is provided for progressively manipulating the articulating section of the instrument relative to the longitudinal axis of the endoscopic portion within an angular sector of rotation.

An apparatus for applying a surgical fastener includes a cartridge which holds a plurality of surgical fasteners in an array, a fastener advancing mechanism, and a mechanism for closing the fasteners, which includes an anvil and laterally moving arms to apply lateral force to bend the legs of the distal fastener inwardly to a closed position. The fasteners can be made of a bioabsorbable material.

Apparatus and clip for fastening body tissue

Apparatus is provided for applying a surgical clamp during endoscopic or laparoscopic procedures which includes a handle portion, an endoscopic portion extending longitudinally from the handle portion, and a surgical clamp detachably mounted adjacent a distal end of the endoscopic portion. The surgical clamp includes opposed cooperating jaw members which are movable between an initially closed position and an open position. Structure is associated with the endoscopic portion of the apparatus for detachably engaging the surgical clamp and a mechanism is provided for moving the opposed cooperating jaws between the initially closed position and the open position and for moving the engaging structure between a disengaged position and an engaged position. Preferably, a distal end portion of the endoscopic portion of the apparatus is adapted to articulate relative the longitudinal axis of the endoscopic portion for increasing the range of operability of the apparatus during surgical procedures.

Surgical clamp apparatus

A surgical clip which comprises a staple having a central portion and first and second legs extending from said central portion. A retainer is provided having an opening dimensioned for passage of an end portion of each of said legs when the legs are bent from an open position to a closed position. A ratchet mechanism is provided in the form of a plurality of teeth disposed on the legs adapted to be engaged by a pawl of said retainer.

Surgical clip

An apparatus for applying a surgical clip which comprises a staple having a central portion and first and second legs extending from said central portion. A retainer is provided having an opening dimensioned for passage of an end portion of each of said legs when the legs are bent from an open position to a closed position. The apparatus comprises staple forming means in the form of a pair of pivotable members movable from an open position to a closed position when slid into engagement with a camming surface. Staple pusher means engage the central portion of the staple and slides the staple distally into contact with an anvil and with the pivotable members to bend the staple legs to their closed position.

Fascia clip and instrument

A two-part fastener for use in septoplasty procedures includes a fastener portion having a base with shaft extending perpendicularly therefrom and a retainer having an aperture for engagement with the shaft. The fastener may include indexing means for positioning the retainer in engagement with the fastener portion at discrete spaced apart locations along the shaft. In another embodiment the shaft is slightly larger in diameter than the aperture in the retainer to effect a frictional engagement. Applicator instruments are also provided. In one embodiment the applicator includes two elongated members pivotally connected in the middle. In another embodiment the applicator includes an elongated body which holds a plurality of septoplasty fasteners. A pivotally connected lower jaw holds a supply of retainers. A pusher member drives the fastener through a curved firing chamber, through body tissue, and into engagement with the retainer.

Septoplasty fasteners and device for applying same

A disposable apparatus is disclosed for applying latchless surgical clips to body tissue in endoscopic surgical procedures. The latchless clips are resiliently biased to a closed configuration. The apparatus includes a frame which is adapted to be gripped by hand, and an endoscopic section connected to the handle and capable of storing surgical clips in preparation for clipping arteries or other body tissue. The apparatus includes means for advancing each clip sequentially, temporarily opening the clip and advancing the clip further to a pair of distal jaws where the clip is positioned around the body tissue and closes around the tissue. Also included are means for closing the jaws about the clip. When the jaws are closed, the clip advancing means is simultaneously positioned to advance the next clip. The present apparatus also makes it possible to partially close a clip without interfering with the sequential movement of the clip advancing mechanism.
