Abstract

Various embodiments are directed to a surgical device including an end effector. The end effector may include a first jaw member defining a first groove and a second jaw member defining a second groove. The first jaw member and the second jaw member may be selectively pivotable between an open position and a closed position. Also, the first groove and the second groove may align to form a combined helical groove when the first jaw member and the second jaw member are in the closed position. In addition, the first jaw member may define a wire opening aligned with the first groove. Further, the first jaw member may define a beveled edge directed distally and substantially parallel to a distal portion of the wire opening.

Claims

1. A surgical device comprising an end effector, wherein the end effector comprises:

a first jaw member defining a first groove;

a second jaw member defining a second groove;

wherein the first jaw member and the second jaw member are selectively pivotable between an open position and a closed position;

wherein the first groove and the second groove align to form a combined helical groove when the first jaw member and the second jaw member are in the closed position; and

wherein the first jaw member defines a wire opening aligned with the first groove; and

a beveled edge directed distally and substantially parallel to a distal portion of the wire opening, wherein the beveled edge is fixedly coupled to the first jaw member such that it cuts a wire when the wire is retracted proximally through the wire opening.

2. The surgical device of claim 1, wherein a distal edge of the first jaw member and a distal edge of the second jaw member define an interlocking pattern.

3. The surgical device of claim 1, further comprising a shaft portion pivotably connected to the first jaw member and the second jaw member.

4. The surgical device of claim 3, wherein the shaft portion comprises a shaft wire opening aligned with the wire opening.

5. The surgical device of claim 4, further comprising a handle, wherein the handle comprises a trigger, and wherein the trigger is actuatable to transition the first jaw member and the second jaw member from the open position to the closed position.

6. The surgical device of claim 1, wherein the first groove and the second groove are positioned at distal portions of the first and second jaw members.

7. The surgical device of claim 1, wherein the first jaw member and the second jaw member comprise a groove section and a tooth section, and wherein the tooth section is positioned distally relative to the groove section.
