    Abstract: A surgical device for providing haptic feedback includes a housing having a cavity defined therein configured to receive a finger of a user and an elongated shaft configured to extend through the housing and into the cavity and configured to support a spring thereon and a pressure contact. A fluid-filled sensor is included that has a plurality of tubes configured to extend from the cavity, each tube includes a fluid-filled bladder at both ends thereof joined by a fluid channel therebetween. Each tube is configured to contain a fluid therein such that when a user's finger is engaged between the fluid-filled bladder at the proximal end of the tubes and the pressure contact, changes in pressure in the fluid-filled bladders at a distal end of the tubes is correspondingly registered in the fluid-filled bladders at the proximal end of the tubes providing haptic feedback to the user.

    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 forceps includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.
