Abstract: An electrosurgical forceps includes first and second shaft members and first and second jaw members extending distally from the respective first and second shaft members. A pivot couples the first and second shaft members with one another such that the first and second shaft members are movable relative to one another between a spaced-apart position and an approximated position to move the first and second jaw members relative to one another between an open position and a closed position. The jaw members are configured to facilitate tissue treatment, tissue division, and blunt tissue dissection.

Abstract: An electrosurgical forceps includes first and second shaft members pivotably coupled to one another via a pivot member 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 knife is translatable between retracted and extended positions. The knife has a stop to prevent distal movement of the knife beyond the extended position.

Abstract: A knife configured for use with an electrosurgical forceps having curved jaw members and a method of manufacturing the same. The knife includes a distal body having an inner side and an outer side, a first etching on the outer side of the distal body defining a distal cutting edge and a second etching on the outer side of the distal body extending along a portion of a length of the distal body to define relatively protruded and relatively recessed surfaces extending along a portion of the length of the distal body on the outer side thereof.

Abstract: An electrosurgical forceps includes a first shaft member including a first inner frame. A first jaw member extends distally from the first inner frame. A first outer housing is supported by the first inner frame. The first inner frame includes a first member stamped from sheet metal. A second shaft member includes a second inner frame. A second jaw member extends distally from the second inner frame. A second outer housing is supported by the second inner frame. The second inner frame includes a second member stamped from sheet metal and a rigid filler member disposed on the second member.

Abstract: An electrosurgical instrument includes a housing and an elongated shaft extending from the housing. An end effector is disposed at a distal portion of the elongated shaft. The end effector is configured to deliver electrosurgical energy to tissue. The end effector includes a first jaw member having a first electrode plate and a second jaw member having a second electrode plate. A movable handle is operably coupled to the housing. The movable handle is configured to move at least one of the first or second jaw members between an open position and a closed position. A first plate is disposed on the first jaw member. A second plate is disposed on the first plate. The second plate includes an opening defined therein. A bead is disposed on the first plate and is configured to protrude through the opening defined in the second plate.

Abstract: A connection mechanism and manufacturing method for a surgical instrument includes an inner shaft member that extends at least partially through an elongated shaft member of the instrument and defines proximal and distal ends and is selectively movable in a longitudinal direction with respect to the elongated shaft member and includes at least one aperture that extends partially along the longitudinal direction and disposed distally from the proximal end. The inner shaft member enables a drive collar member to slide on the inner shaft member and reciprocate along the longitudinal direction. A drive collar stop member slides on the inner shaft member and moves along the longitudinal direction. The drive collar stop member then moves in a direction relative to the longitudinal axis to engage the aperture and limit further longitudinal motion of the drive collar member. An inner shaft stop member limits movement of the inner shaft.

Abstract: An electrosurgical instrument includes at least one shaft member, an end effector assembly extending distally from the at least one shaft member, and a heat pipe. The end effector assembly includes first and second jaw members, each including an electrically-conductive tissue-contacting surface. At least one of the first or second jaw members is movable relative to the other about a pivot between a spaced-apart position and an approximated position for grasping tissue between the electrically-conductive tissue-contacting surfaces. The heat pipe includes a proximal body portion and a flattened distal portion. The proximal body portion extends through at least a portion of the at least one shaft member, and the flattened distal portion extends through at least a portion of the first jaw member. The heat pipe is configured to facilitate drawing heat proximally from the end effector assembly.

Abstract: A surgical instrument includes an elongated shaft having a distal portion and a proximal portion coupled to a housing. An inner shaft member extends at least partially through the elongated shaft and is selectively movable in a longitudinal direction. An end effector is supported by the distal portion of the elongated shaft. The end effector includes upper and lower jaw members pivotally coupled to the distal portion of the elongated shaft about a pivot axis and including a pair of laterally spaced flanges. The pairs of flanges of the jaw members are arranged in an offset configuration such that one flange of the upper jaw member is positioned on a laterally exterior side of a corresponding flange of the lower jaw member, and the other flange of the upper jaw member is positioned on a laterally interior side of the other flange of the lower jaw member.
