Abstract: An articulation mechanism for a surgical instrument includes an articulation assembly, a plurality of cables, and a trigger. The cables are coupled to the articulation assembly at a proximal end thereof and extend distally therefrom. The cables are configured to engage an end effector assembly of the surgical instrument at a distal end thereof. The trigger is coupled to the articulation assembly and is selectively moveable from a shipping position to a use position. In the shipping position, the cables are substantially un-tensioned. In the use position, the cables are disposed in an initial tensioned position. In the use position, the trigger is moveable between an unlocked position and a locked position. In the unlocked position, the cables are selectively tensionable to articulate the end effector assembly. In the locked position, the tensions on the cables are maintained to lock the end effector assembly in position.

Abstract: An improved distal end for a ligating band dispenser having a transverse groove or ridge profile that promotes rolling of the bands. In one embodiment, the ligating bands and the transverse grooves or ridges are dimensioned such that the width of the bands when stretched on the support surface is substantially the same as the pitch of the transverse grooves or ridges. Having the width of the bands when stretched on the support surface be substantially the same as or less than the pitch of the transverse grooves or ridges allows the bands to fit within the grooves, which helps insure that the bands are sufficiently held back by the ridge crests to induce a rolling action. In addition, the transverse grooves or ridges may also be dimensioned such that the height of the ridge crests is sufficiently high to insure that the bands are sufficiently held back by the ridge crests to induce a rolling action.

Abstract: A surgical device for performing surgery generally includes a handle assembly, an elongate member extending from the handle assembly, an articulation mechanism operatively associated with the handle assembly, and an end effector. The elongate member has an articulating section and straight section. The articulating section is configured to articulate with respect to the straight section. The articulation mechanism is operatively associated with the handle assembly and the articulating section such that the articulating section articulates toward a first direction relative to the straight section upon movement of the handle assembly towards the first direction with respect to the straight section. The end effector is operatively coupled to the articulating section of the elongate member and includes first and second jaw members. The surgical device further includes a locking mechanism configured for fixing a relative position of first and second jaw members.

Abstract: The present invention regards an apparatus for selectively and accurately deploying one or more sequentially positioned medical appliances from a portable medical device. The apparatus includes a body having a channel, a string passing through the channel, and a mechanism for moving the string predetermined distances to deploy medical appliances. The medical appliances may be, but are not limited to, ligation bands.

Abstract: An improved cutting assembly for use with a surgical instrument is provided and includes a pair of cutting blades pivotally mounted on a yoke and a drive member engageable with the cutting blades to move the cutting blades between an open position substantially spaced apart from each other to a closed position wherein the cutting blades are in close cooperative alignment to cut tissue. One or more biasing members are provided adjacent the cutting blades to prevent the cutting blades from splaying or separating during the cutting of tissue.

Abstract: An improved distal end for a ligating band dispenser having a transverse groove or ridge profile that promotes rolling of the bands. In one embodiment, the ligating bands and the transverse grooves or ridges are dimensioned such that the width of the bands when stretched on the support surface is substantially the same as the pitch of the transverse grooves or ridges. In another embodiment, the ligating bands and the transverse grooves or ridges are dimensioned such that the width of the bands when stretched on the support surface is less than the pitch of the transverse grooves or ridges. Having the width of the bands when stretched on the support surface be substantially the same as or less than the pitch of the transverse grooves or ridges allows the bands to fit within the grooves, which helps insure that the bands are sufficiently held back by the ridge crests to induce a rolling action.
