摘要： An electrosurgical instrument includes a housing having a shaft attached thereto which connects a pair of first and second jaw members such that the jaw members are movable relative to one another to grasp tissue therebetween. The instrument also includes a four-bar handle assembly attached to the housing for actuating a drive rod assembly. The handle assembly includes a handle and a cam-like piston which cooperate to impart a uniform closure pressure against tissue grasped between the jaw members. The instrument also includes a rotating assembly for rotating the jaw members, a knife assembly for separating tissue and a pair of electrical leads connect the jaw members to a source of electrical energy. The electrical leads include slack loops disposed in the rotating assembly which permit rotation of the jaw members about the axis.

摘要： A 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 assembly having a four-bar mechanical linkage which cooperates with a drive assembly to impart movement to the first and second jaw members from the first and second positions.

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 for surgically joining a tissue is disclosed. The surgical instrument comprises a handle assembly, an elongate portion extending distally from the handle assembly, a pair of opposed jaw members, and a tissue stop. The tissue stop is mechanically engaged with a first jaw member and is configured to retain the tissue between jaw members. The tissue stop is movable between a first position, where a stopping portion of the tissue stop is disposed between a tissue-contacting surface of the first jaw member and a tissue-contacting surface of the second jaw member, and a second position, where the stopping portion is between the tissue-contacting surface of the first jaw member and a lower surface of the first jaw member. A portion of the tissue stop is made of stamped metal section and a portion of the tissue stop is made of an overmolded plastic section.

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.
