International Classification:

A61B 18/14
A61B 18/12
A61B 90/00

Abstract:

A surgical system and a computing device for a surgical system that is configured to calculate actual operating parameters of an electrosurgical instrument, including an actual angle between the jaw members of the electrosurgical instrument, and to display a user interface. The user interface includes an ideal angle range between the jaw members and the actual angle between the jaw members of the electrosurgical instrument relative to the ideal angle range. The computing device is further configured to determine if the actual angle between the jaw members of the electrosurgical instrument is outside the ideal angle range.

International Classification:

A61B 18/14
A61B 90/00

Abstract:

An electrosurgical instrument includes an end effector assembly including first and second jaw members. At least one of the first or second jaw members is movable about a pivot relative to the other from a spaced-apart position to an approximated position to grasp tissue between first and second opposed surfaces of the first and second jaw members, respectively. The electrosurgical instrument further includes an interface configured to provide a feedback related to a size of tissue grasped by the first and second jaw members. At least one of the first or second jaw members includes a touch sensor configured to sense a touch span where the tissue touches the at least one of the first or second opposed surfaces. The end effector assembly further includes an angle sensor configured to sense an angle α about the pivot between the first and second opposed surfaces.

International Classification:

A61B 18/12
G06N 20/00

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.

International Classification:

A61B 18/14
A61B 18/12

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.

A61B 34/00
G01N 33/00

Abstract:

A method of surgery includes inserting a surgical instrument into a surgical site, supplying energy from a surgical generator to tissue at the surgical site via the surgical instrument to treat the tissue, sensing at least one property of smoke at the surgical site, and determining at least one parameter of smoke at the surgical site based upon the at least one property. The method further includes controlling the supply of energy from the surgical generator based upon the at least one parameter and/or providing an output based upon the at least one parameter.

Abstract:

An electrosurgical system includes an end effector assembly and an electrosurgical generator. The end effector assembly includes first and second jaw members, one or both of which is movable relative to the other for grasping tissue between tissue-contacting surfaces thereof. One or both of the jaw members includes a sensor configured to sense at least one property associated with the grasped tissue. The electrosurgical generator includes a controller and an energy output configured to supply electrosurgical energy to the tissue-contacting surface of one or both of the jaw members for conduction through the grasped tissue to seal the grasped tissue. The controller is configured to receive the at least one sensed property, determine at least one condition of collagen within the grasped tissue based upon the at least one sensed property, and control the energy output based upon the determined at least one condition of the collagen within the grasped tissue.
