摘要： 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. In one embodiment, the tool mechanism including a pair of tissue gripping members having a plurality of rib members extending in a lengthwise direction, and at least one indentation having a longitudinal dimension at least greater than a transverse dimension between the rib members. 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.

摘要： 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.

摘要： An apparatus is provided for applying surgical clips which includes provisions for applying a partially closed clip to ducts or shunts during a surgical procedure such as cholecystectomy procedures. The apparatus includes means for effecting a partial closing stroke of the handle mechanism to correspond to a partial closure of the jaw members, and permits a partial opening stroke to release the partially closed clip in the jaw mechanism. Other features of the invention include means for preventing over advancement of a clip to the jaw mechanism, means for cradling the clip as it is advanced from the clip supply to the jaw mechanism, means for preventing splaying of the jaws in the event of a clip-over-clip application, and a novel rotation collar.
