Surgical instrument with jaw member

摘要

A surgical instrument for supplying energy to tissue may comprise a handle, a trigger, an electrical input, and a shaft extending from the handle. The surgical instrument may comprise an end effector first and second tissue engaging surfaces that are slanted with respect to a transection plane. The end effector may, for example, have an electrode defining a V-shaped cross sectional profile. The end effector may comprise a plurality of raised surfaces that are received by a plurality of indentions when the end effector is in the closed position. The end effector may comprise a cutting member having a plurality of bands.

1. A surgical instrument for supplying energy to tissue, comprising:
a handle, comprising:
a trigger; andan electrical input; a shaft extending from the handle, wherein the shaft comprises a conductor, and wherein the trigger is selectively actuatable to electrically couple the electrical input and the conductor; and an end effector defining a longitudinal axis, comprising:
a first jaw member;a second jaw member, wherein at least one of the first jaw member and the second jaw member is movable relative to the other of the first jaw member and the second jaw member between an open and closed positions to clamp tissue intermediate the first jaw member and the second jaw member in the closed position;the first and second jaw members defining a channel;a cutting member including a distal end, wherein the cutting member is sized and configured to fit at least partially within the channel, the cutting member configured to translate along the channel between a retracted position and a fully advanced position, the cutting member comprising at least a first, second, and third bands, wherein the second band is disposed intermediate the first and third bands and comprises a sharp distal cutting element; andat least one compression element extending from the cutting member, wherein the at least one compression element engages one of the first and second jaw members to move the first and second jaw members from the open position to the closed position when the cutting member translates with respect to the first jaw member beyond the retracted position.
