Abstract: A forceps is provided and 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 at least one of 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.

Abstract: A knife limit for a surgical instrument includes a housing having a shaft extending therefrom configured to support an end effector at a distal end thereof, the end effector including first and second jaw members. One or both of the jaw members including a knife channel defined therein and extending therealong to a distal portion thereof. A knife assembly is disposed within the housing and cooperates with a trigger to translate a knife within the knife channel to the distal portion of the jaw member upon actuation thereof. A knife limit button is disposed within the housing and is configured to limit the distal translation of the knife within the knife channel upon selective actuation thereof. The knife limit button is movable between a first position allowing full translation of the knife within the knife channel and a second position limiting distal translation of the knife within the knife channel.

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: A method for treating tissue includes determining whether tissue is present between first and second jaw members. In a case where it is determined that tissue is present between the first and second jaw members, the method further includes determining whether activation has been initiated. In a case where it is determined that activation has been initiated, the method further includes supplying electrosurgical energy to the first and second jaw members to seal the tissue and, if it is determined that sealing is complete: stopping the supply of electrosurgical energy; activating a thermal cutting element to supply thermal energy to cut the sealed present tissue; determining if thermal cutting is complete; and, in a case where it is determined that the thermal cutting is complete, stopping and the supply of thermal energy.

Abstract: An electrosurgical system includes an end effector assembly and a sensor. The end effector assembly includes first and second jaw members each defining an electrically-conductive tissue-contacting surface. At least one of the first or second jaw members is movable relative to the other between a spaced-apart position and an approximated position for grasping tissue between the tissue-contacting surfaces thereof. The electrically-conductive tissue-contacting surfaces of the first and second jaw members are adapted to connect to a source of electrosurgical energy for conducting energy through tissue grasped therebetween to treat tissue. The sensor is configured to sense at least one property of smoke produced as a result of the conduction of energy through tissue grasped between the electrically-conductive tissue-contacting surfaces.

Abstract: A surgical system includes a surgical instrument configured for insertion into a surgical site, a sensor configured to sense at least one property of smoke at the surgical site, and a surgical generator including a controller and an energy output. The energy output is configured to supply energy to the surgical instrument for application to tissue at the surgical site to treat the tissue. The controller is configured to receive the at least one property, determine at least one parameter of smoke at the surgical site based upon the at least one property, and control the energy output based upon the at least one parameter and/or provide an output based upon the at least one parameter.

Abstract: A tissue resection device includes a handpiece and an end effector assembly extending distally from the handpiece. The end effector assembly includes an outer shaft defining a longitudinal axis and including a window defined therethrough towards a distal end thereof. The end effector assembly further includes an inner member rotationally disposed within the outer shaft. The inner member includes a proximal body portion and a distal cutting portion. The proximal body portion is coaxially disposed on the longitudinal axis and rotatable thereabout. The distal cutting portion includes an offset portion that is radially offset from the longitudinal axis and is configured to orbit about the longitudinal axis. At least a portion of the distal cutting portion is a thermal cutting element configured to heat in response to application of electrical energy thereto.
