Abstract: A surgical end effector assembly includes first and second jaw members configured to grasp tissue. Each of the first and second jaw members includes a proximal flange portion and a distal body portion. The proximal flange portions are pivotably coupled to one another to move the distal body portions between a spaced-apart position and an approximated position.

Abstract: A jaw member of a surgical instrument includes a structural frame, an insulative spacer supported on the structural frame, an electrically conductive tissue contacting plate supported on the insulative spacer, and a lead wire. The spacer defines a pocket at an upper portion thereof and includes a channel extending from the pocket, through the spacer, to a bottom portion of the spacer. The channel defines a substantially U-shaped configuration having first and second radiused corners at the bottom portion of the spacer. The lead wire is attached to an underside of the plate at an attachment point within the pocket and extends distally from the attachment point into the channel, through the channel, over the first and second radiused corners, and proximally from the jaw member. The lead wire is adapted to connect to a source of energy to energize the plate for treating tissue.

Abstract: A vessel sealing instrument includes a housing having a shaft extending from a distal end thereof having an end effector assembly including a pair of opposing first and second jaw members operably coupled thereto. A drive assembly is disposed within the housing and is configured to move the jaw members upon actuation thereof between an open position and a closed position for clamping tissue with a closure pressure within the range of about 3 kg/cm2 to about 16 kg/cm2. An anti-backdrive assembly is operably disposed within the housing and includes a drive wedge. A solenoid controller is operably coupled to the drive wedge and is configured to selectively move the drive wedge into the drive assembly upon activation thereof to increase the closure pressure between the jaw members in response to tissue expansion during sealing.

Abstract: A surgical instrument includes a housing, a shaft extending therefrom, an end effector assembly supported by the shaft, a movable handle, and a drive assembly. The drive assembly includes a translatable drive member for actuating the end effector assembly, and a torsion spring including first and second legs. The first leg is configured to translate through the housing in response to movement of the movable handle relative to the housing. The second leg is configured to translate through the housing in cooperation with the first leg to move the drive member longitudinally when a force acting on the drive member is less than a threshold force, and to remain in fixed position, thereby tensioning the torsion spring and retaining the drive member in fixed position when the force acting on the drive member is equal to or exceeds the threshold force.

Abstract: A surgical instrument includes a housing, a shaft extending therefrom and supporting an end effector, a knife, and a trigger assembly. The knife is configured to translate between retracted and extended positions. The trigger assembly includes a trigger movable relative to the housing between un-actuated and actuated positions, and a linkage including an apex and first and second bases. The apex is rotatably coupled to the housing about a pivot. The first base is disposed on a first side of the apex and coupled to the trigger. The second base is disposed on a second side of the apex and coupled to the knife. In response to movement of the trigger from the un-actuated to the actuated position, the first base is moved proximally, the apex is rotated about the pivot, and the second base is moved distally to move the knife from the retracted to the extended position.

Abstract: A robotic surgical instrument includes a housing, a shaft assembly extending distally from the housing, and an end effector assembly. The shaft assembly has a proximal segment coupled to the housing, a clevis supporting the end effector assembly, and at least one articulating link pivotably coupled to and interconnecting the proximal segment and the clevis such that the end effector assembly is configured to articulate relative to the proximal segment via the at least one articulating link in at least two directions.

Abstract: A vessel sealing instrument includes a housing having a shaft extending from a distal end thereof including an end effector assembly having opposing first and second jaw members operably coupled thereto. One of the jaw members moveable between open and closed positions for clamping tissue with a closure pressure within the range of about 3 kg/cm2 to about 16 kg/cm2. The jaw members are adapted to connect to a generator for providing energy thereto in accordance with a sealing algorithm. An anti-backdrive mechanism is associated with the end effector assembly and includes: a drive shaft coupled to a controller and a screw on opposite ends, the screw configured to engage one of the jaw members upon extension thereof to provide additional closure pressure therebetween. The drive shaft is rotatable by the controller to extend the screw in response to tissue expansion during sealing based on the sealing algorithm.

Abstract: A forceps includes an end effector assembly having first and second jaw members, each including a proximal flange and a distal jaw body defining a tissue-treating surface. The second jaw member is both proximally offset and spaced-apart from the first jaw member. One or more resilient bands extends between and interconnects the proximal flanges of the jaw members. The resilient band(s) is configured to bias the first and second jaw members towards an open position. The resilient band(s) is configured to flex in response to distal translation of the second jaw member relative to the first jaw member to thereby move the second jaw member relative to the first jaw member to a closed position for grasping tissue between the tissue-treating surfaces thereof. In the closed position, the second jaw member is disposed in an aligned orientation and is approximated relative to the first jaw member.
