A method of assembling a jaw member of an electrosurgical forceps includes aligning in vertical registration an electrically conductive seal plate, an insulative spacer and a jaw support. The method further includes stacking the seal plate atop the insulative spacer and the jaw support such that a flange depending from the seal plate seats within a corresponding cavity defined within a flange depending from the insulative spacer which, in turn, seats within a cavity defined within the jaw support. The method further includes mechanically securing the seal plate, insulative spacer and jaw support to one another and securing a jaw housing to surround the jaw support, the insulative spacer and the seal plate.

Provided are Scissors for an endoscope that include a scissor mechanism part that includes a pair of scissor members connected to each other by a first spindle, and cuts a target site by opening and closing of the one scissor member and the other scissor member with the first spindle as a fulcrum; and an electrode part in which a monopolar electrode (electrode part) is formed on a distal end part of the one scissor member of the one scissor member and the other scissor member. An operator can quickly and extensively cut the target site by using the scissor mechanism part by the pair of scissor members, or can stop bleeding at the target site or cut the target site by using the electrode part.

Various methods of treating a heart of a patient having a cardiac arrhythmia are disclosed. The method can comprise dissecting tissue at an inferior aspect of a right inferior pulmonary vein of the patient to create an oblique sinus defect, dissecting tissue to open a space between a superior vena cava and a left atrium, and dissecting tissue to open a space across a transverse sinus between a pulmonary artery and a roof of the left atrium. The method can further comprise passing a catheter through an oblique sinus defect underneath the heart and beyond a left ventricle and passing a first flexible guiding device across the transverse sinus and under the superior vena cava and the pulmonary artery.

A surgical instrument is disclosed including a transducer configured to provide vibrations along a longitudinal axis, an end effector operably coupled to the transducer, and a stationary lower jaw extending parallel to the end effector. The end effector extends along the longitudinal axis. The end effector comprises a blade. The stationary lower jaw comprises a clamp face positioned distal to the blade. The end effector is movable relative to the stationary lower jaw to drive the blade distally towards the clamp face. The end effector comprises a hollow lumen. The end effector further comprises at least one member extended across a portion of the hollow lumen.

An electrosurgical forceps includes first and second shaft members pivotably coupled to one another such that pivoting of the first and second shaft members between spaced-apart and approximated positions pivots jaw members thereof between open and closed positions. A proximal end portion of the second shaft member may be pivoted against a resilient bias of a spring element to apply a predetermined clamping pressure on tissue and ultimately engage an activation switch to delivery electrosurgical energy to the clamped tissue.

An end effector assembly suitable for use with a forceps includes opposing first and second jaw members pivotably mounted with respect to one another. The first jaw member includes one or more pivot holes defined therein configured to receive a portion of a pivot pin therein. The end effector assembly also includes an electrically-insulative hinge configured to electrically isolate the first and second jaw members from one another including one or more pivot-hole locators having an aperture defined therein. The electrically-insulative hinge is attached to the first jaw member such that the one or more pivot-hole locators align with the one or more pivot holes of the second jaw member.

Surgical robot systems for remote manipulation having robotic telemanipulators are provided. The surgical robot systems are well adapted for use by the surgeon, seamlessly integrateable into the operation room, allow for a surgeon to work between the robot and the patient throughout a surgery in a sterile manner, are relatively low cost, and/or permit integrated laparoscopy. The system preferably includes a master console having a plurality of master links interconnected by a plurality of master joints, and a handle coupled to the master console for operating the telemanipulator. The system further includes a slave console operatively coupled to the master console and having a plurality of slave links interconnected by a plurality of slave joints that move responsive to movement at the master console to permit an end-effector to perform surgery.

A surgical instrument end effector assembly includes a first jaw member defining an insulative tissue-contacting surface and first and second electrically-conductive tissue-contacting surfaces, and a second jaw member positioned including an ultrasonic blade body and defining at least one electrically-conductive tissue-contacting surface. The first jaw member is movable relative to the second jaw member between a spaced-apart position and an approximated position to grasp tissue therebetween. The second jaw member is movable relative to the first jaw member between a first configuration, to facilitate transmission of ultrasonic energy to tissue grasped between the first and second jaw members, and a second configuration, to facilitate conduction of electrosurgical energy through tissue grasped between the first and second jaw members.

A surgical instrument with a handle for a surgical instrument is provided, comprising a first arm and a second arm, wherein at least one of the arms being movable with respect to the other between an open and closed position. An end effector such as a pair of opposing jaws for grasping tissue may be disposed at the distal end of the two arms. At the proximal end of each arm is a finger loop, or some other suitable means for holding by the handle, which are used to actuate the arms between the open and closed position. At least one of the finger loops is arranged to pivot about the longitudinal axis of the arm from which it extends, for example, the finger loop may be connected to the arm by a hinged connection, or any other suitable connection for enabling the finger loop to be pivotably rotated.

A surgical system according to one or more embodiments may include: manipulators respectively supporting an endoscope and first and second surgical instruments; a remote control apparatus including a display device, a first operation handle for right hand to operate the first surgical instrument, and a second operation handle for left hand to operate the second surgical instrument; and a control apparatus. The control apparatus may display, on the display device, a graphical user interface, overlapped with the image captured by the endoscope, the graphical user interface including a first area that displays information on the first surgical instrument to be operated by the first operation handle, a second area that displays information on the second surgical instrument to be operated by the second operation handle, and a third area that displays information on the endoscope, which are arranged side by side in order from right to left.
