A polymeric, surgical clip having first and second curved leg members joined at their proximal end by a reduced thickness hinge portion and movable from an open position to a closed position for clamping a vessel between curved opposing inner surfaces which are substantially parallel when the clip is closed. The first leg member has a concave inner surface and a hook portion at its distal end curved toward the second leg member. The clip includes a sharp distal tip on the end of the hook portion and a sharp pointed penetrating member on the outer surface of the distal end of the hook portion. The distal end of the second leg has a longitudinal groove through which the sharp pointed penetrating member and then the sharp distal tip passes when the legs are closed. The second leg member further comprises a pair of sharp penetrating member attached to each side of the distal end on either side of the groove. These cooperate with the penetrating member of the first leg and sharp distal tip to cut tissue attached to the vessel to be clamped. A ligating clip applying instrument for applying the clip has a pair of handles pivoted about a hinge point and extends beyond the hinge point to form a pair of clip closing jaws equipped with means for engaging bosses located on the sides of the first and second leg members.
This is a divisional application of application Ser. No. 07/422,464 filed Oct. 17, 1989, now U.S. Pat. No. 5,062,846, which is a continuation-in-part of application Ser. No. 329,453, filed Mar. 28, 1989, now abandoned, which was a divisional of application Ser. No. 206,143, filed Jun. 13, 1988, now U.S. Pat. No. 4,834,096, issued May 30, 1989, which was a continuation-in-part of application Ser. No. 112,599, filed Oct. 26, 1987, now abandoned.
A two-part ligation clip applicator comprises a handle assembly having a squeezable trigger and an elongated shaft connected at its proximal end to the handle assembly. The elongated shaft houses a sliding advancer which is actuated by squeezing the trigger to move axially in a forward direction in the shaft. In addition, a module is mountable at a distal end of the elongated shaft and supports a ligation clip. The module has a cartridge housing, latches pivotably mounted within the housing for gripping first part of the ligation clip, and a sliding pusher slidable within the housing by actuation of the advancer to engage the second part of the ligation clip and advance it relative to the first part to close the first part.
A polymeric, surgical clip having first and second curved legs with each having a pair of opposing side surfaces joined at their proximal ends by a flexible hinge section and movable from an open position to a closed position for clamping a vessel between curved opposing inner surfaces. The first leg terminates at its distal end in a female locking member, and the second leg member terminates in a male locking member complimentary to the female locking member such that when the first and second leg members are moved from an open position to a closed position about the hinge section the male member is lockingly engaged in the female locking member. The clip has at least one cutting guide extending outward from and disposed along at least a portion of the length of at least one of the side surfaces of at least one of the first and second legs. The cutting guide aids in cutting the ligated tissue a safe distance from the clip such that a tissue cuff is formed.
A surgical clip removal instrument having operative surfaces at the distal jaws that directly compress the legs of a latched surgical clip and upon limited closure movement differentially elongate the clip legs to achieve an unlatched condition. Upon release of the jaws, the inherent resiliency of the clip outwardly biases the legs while maintaining contact with the jaws, allowing removal of the clip from the surgical site in a single piece.
A surgical device and cooperating cartridge for applying surgical clips during endoscopic surgery. The surgical device incluces a jaw assembly, a barrel assembly, and a handle assembly. The jaw assembly has movable jaw members, each including a substantially transverse grooved portion and at least one angular side shield extending inwardly from an upper and a lower portion of the jaw member. The jaw members are oriented at an angle of approximately 22.degree. relative to the longitudinal axis of the barrel portion. The distal surface of each jaw member is oriented at an angle that extends distally and outwardly. The jaw members are insertable into a unique cooperating cartridge that retains the surgical clip.
A polymeric, surgical clip having first and second curved leg members joined at their proximal end by a hinge portion and movable from an open position to a closed position for clamping a vessel between curved deposing inner surfaces which are substantially parallel when the clip is closed. The first leg terminates at its distal end in a deflectable hook member defining a crest or cutting edge along at least a portion of the outer surface thereof, and the second leg member terminates in a locking portion complimentary to the hook member such that when the first and second leg members are moved from an open position to a closed position about the hinge means the hook member will deflect about the distal end of the second leg member to lock the clip in a closed position. The deflection of the hook member will serve to cut connective tissue adjacent a vessel or the like to be clamped when the leg members are closed to aid in locking the clip in the closed position about the vessel or the like to which the surgical clip is applied.
