Abstract: An end effector assembly for a surgical instrument includes first and second jaw members each including a jaw housing, an electrically-conductive tissue-treatment plate, and a longitudinally-extending channel. The first and/or second jaw member is movable relative to the other between a spaced-apart position and an approximated position. A cutting mechanism is disposed at least partially within the second jaw member. The cutting mechanism may include an inflatable bladder, a fluid line coupled to the inflatable bladder, and a knife coupled to the inflatable bladder. The cutting mechanism may alternatively include a fluid line, a knife, and a sealing member that defines a variable-volume sealed chamber within the longitudinally-extending channel of the second jaw member. The cutting mechanism may alternatively include at least one electromagnet, at least one electrical wire coupled to the at least one electromagnet, and a knife operably coupled to the at least one electromagnet.

Abstract: A colpotomy system includes a colpotomy cup that extends to a distal surface and defines a longitudinal axis. The colpotomy system further includes a cutter operably coupled to the colpotomy cup and configured to travel along an arcuate path defined about the distal surface of the colpotomy cup. The cutter actuatable to separate a uterus from a vagina as the cutter rotates about the longitudinal axis of the colpotomy cup.

Abstract: A tissue closure system for closing vaginal tissue includes a tissue closure device having an end effector supporting one or more sutures securable to vaginal tissue. The one or more sutures may be separated from the end effector and tied to the vaginal tissue. The tissue closure system may include a tissue approximation device configured to apply negative pressure to vaginal tissue for approximating portions of the vaginal tissue together.

Abstract: An end effector assembly configured for use with a surgical instrument or surgical system includes first and second jaw members each including an outer jaw housing, a tissue-treating plate, and a longitudinally-extending channel therethrough. At least one of the first or second jaw members is pivotable relative to the other between a spaced-apart position and an approximated position. A cutting mechanism is configured to cut tissue grasped between the jaw members. The cutting mechanism may include an activation member coupled to a knife and configured to advance the knife transversely between the jaw members, a heat-activated elongated sheet configured to un-roll to advance a cutting edge thereof transversely between the jaw members, or a clutch and spring mechanism configured to deploy a knife longitudinally between the jaw members.

Abstract: A colpotomy system includes an energy source and a uterine manipulator that is electrically coupled to the energy source. The uterine manipulator supports a colpotomy cup and extends to a conductive distal tip portion. The colpotomy cup includes a conductive surface. One or both of the conductive distal tip portion and the conductive surface of the colpotomy cup are configured to return monopolar energy to the energy source.

Abstract: A surgical system includes an attaching device having an end effector disposed at the distal end thereof. The end effector includes a support member, a wrist pivot pivotably coupling the end effector to the attaching device, and first and second jaw members pivotably coupled to one another and the support member. A first cable is operably coupled to the wrist pivot and configured to articulate the end effector relative to the attaching device. Second and third cables are operably coupled to the jaw members and configured to pivot the jaw members relative to the support member. A first actuation of the second and third cables collectively pivots the first and second jaw members relative to the support member. A second actuation of the second and third cables pivots the first and second jaw members relative to one another and the support member between a spaced-apart position and an approximated position.
