发明名称 Surgical forceps
摘要 A forceps includes a housing, a shaft, and an end effector assembly. The end effector assembly includes first and second jaw members. At least one of the jaw members is moveable with respect to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. A cutting member having a plurality of cutting edges symmetrically-disposed about a longitudinal axis thereof is disposed within the shaft and is longitudinally translatable between a retracted position and an extended position. The cutting member extends between the jaw members to cut tissue grasped therebetween when in the extended position. The cutting member is fixedly-oriented with respect to the shaft and is configured for translation between the jaw members to cut tissue therebetween when the jaw members are rotated with respect to the shaft between about zero degrees and about 180 degrees in at least one of the clockwise and counterclockwise directions.

主权项 1. A forceps, comprising: a housing having a shaft attached thereto and an end effector assembly disposed at a distal end of the shaft, the shaft defining a longitudinal axis, the end effector assembly including: first and second jaw members disposed in opposed relation relative to one another, at least one of the jaw members moveable with respect to the other between a spaced-apart position and an approximated position for grasping tissue therebetween, the first and second jaw members rotatable about the longitudinal axis and relative to the shaft through a plurality of rotational positions; and a cutting assembly including a cutting member rotationally fixed with respect to the shaft, the cutting member including at least one cutting edge, the cutting member disposed within the shaft and longitudinally translatable between a retracted position, wherein the cutting member is disposed proximally of the first and second jaw members, and an extended position, wherein the cutting member extends at least partially between the jaw members to cut tissue grasped between the jaw members, the cutting member configured for translation between the retracted and extended positions at each of the plurality of rotational positions of the jaw members with respect to the shaft.
