A surgical instrument is provided for performing a variety of endoscopic or laparoscopic procedures including the electrocauterization of tissue. The instrument includes a handle assembly, a tubular body extending from the handle assembly therein defining a longitudinal axis, a tool assembly associated with a distal end of the tubular body including a tool base and tool members, an electrical connector electrically associated with the tool members, electrical insulation being provided in association with electrical conducting components, a first mechanism for effectuating remote articulation of the tool assembly with respect to the longitudinal axis of the tubular body, and a second mechanism for effectuating remote rotation of the tool assembly about the longitudinal axis of the tubular body.
A surgical apparatus comprising: a handle portion; a tubular body portion extending from said handle portion and defining a longitudinal axis, said tubular body portion including an inner electrical insulating member and an outer electrical insulating member; a tool assembly associated with a distal
A surgical apparatus comprising: a handle portion; a tubular body portion extending from said handle portion and defining a longitudinal axis, said tubular body portion including an inner electrical insulating member and an outer electrical insulating member; a tool assembly associated with a distal end portion of said tubular body portion, said tool assembly including a tool base portion and tool means; connector means in association with said handle portion for delivering an electrical current to said tool assembly; means for effectuating remote articulation of said tool assembly between a first position substantially parallel to said longitudinal axis of said body portion and a second position substantially angularly disposed with respect to said longitudinal axis of said body portion; and means for effectuating remote rotation of said tool assembly about the longitudinal axis of said body portion relative to said handle assembly, wherein said means for effecting remote rotation comprises a rotation assembly including an axially rotatable collar member associated with said handle portion, and an outer tubular member extending from said collar member, through said body portion, to said tool assembly.
