摘要： An electrosurgical instrument includes a housing having a shaft attached thereto which connects a pair of first and second jaw members in an opposing manner relative to one another. The jaw members are movable relative to one another from a first open position wherein the jaw members are disposed in spaced relation relative to one another to a second closed position wherein the jaw members cooperate to grasp tissue therebetween. The instrument also includes a handle which imparts movement of the first and second jaw members from the first and second positions and a rotating assembly for rotating the jaw members about a longitudinal axis defined through the shaft. A pair of electrical leads connect the jaw members to a source of electrical energy such that the jaw members are capable of conducting energy through tissue held therebetween. The leads include a slack-like loop disposed in the rotating assembly which permits rotation of the jaw members about the longitudinal axis without unduly straining the electrical leads.

摘要： A surgical instrument includes a frame structure defining proximal and distal portions. The proximal portion has an articulating arm for repositionably mounting to a base and the distal portion supporting a stabilizing member. An attachment mounts on the stabilizing member, the attachment being configured and dimensioned such that upon contact with the heart the engaged heart tissue bulges outward. A method of surgery using the attachment includes providing a frame structure defining proximal and distal portions, the proximal portion being repositionably mountable to a base, supporting an attachment on the stabilizing member and engaging heart tissue with the attachment such that the tissue bulges outward to better present the tissue for surgery.

摘要： An electrosurgical instrument for treating tissue includes a housing having a shaft extending therefrom having an axis A-A defined therethrough. The shaft is at least partially flexible and includes first and second jaw members attached at a distal end thereof. Each jaw member includes an electrically conductive tissue contacting surface adapted to connect to a source of electrosurgical energy such that the electrically conductive tissue contacting surfaces are capable of conducting electrosurgical energy through tissue held therebetween. A drive assembly is disposed in the housing and has a first actuator operably coupled to a drive rod for reciprocation thereof to move the jaw members from a first position in spaced relation to one another to a second position closer to one another for engaging tissue. A second actuator is disposed on the housing and is actuatable to articulate the shaft.
