A system includes a surgical instrument configured to perform a laparoscopic surgical operation, a location sensor configured to identify a spatial relationship between an anatomical structure and the surgical instrument, and a processor configured to receive a graphical representation of a patient, determine proximity of the distal end portion of the surgical instrument with the anatomical structure of the patient based on the spatial relationship, and generate a warning based on the determination of proximity.

System and methods for determining proximity relative to an anatomical structure

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.

Surgical instruments and systems configured to detect, analyze, and/or distinguish smoke and steam during a surgical procedure

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.

Surgical system and methods for treating tissue

A method of performing a tissue seal utilizing a robotic surgical system includes grasping tissue between a pair of jaws of an electrosurgical instrument; displaying on a display a visual representation of the grasped tissue; emitting electrosurgical energy from the pair of jaws into the tissue; and displaying on the display a visual representation of a progress of the tissue seal.

Systems and methods for performing a tissue seal

An electrosurgical system includes an end effector assembly, a display, and a controller. The end effector assembly includes first and second jaw members each defining a tissue-treating 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-treating surfaces thereof. At least one of the first or second jaw members includes a sensor. The controller is configured to receive sensor data from the sensor, generate a tissue indication based upon the sensor data, and output the tissue indication to the display. The display is configured to display the tissue indication. The tissue indication indicates a location along the first jaw member at which tissue is grasped between the tissue-treating surfaces of the first and second jaw members.

Electrosurgical forceps including tissue indication

A computer-implemented method of object enhancement in endoscopy images includes capturing an image of an object within a surgical operative site via an imaging device, determining a size of the object based on the captured image of the object, displaying the captured image of the object, and displaying on the displayed captured image of the object a representation of the determined size of the object.

Systems and methods for object measurement in minimally invasive robotic surgery

A method includes providing a graphical representation of a surgical site, grasping the tissue of the patient with first and second jaw members of an end effector including a location sensor, illuminating optical light into the grasped tissue at the first jaw member, receiving the optical light that has passed through the grasped tissue, at the second jaw member, processing the received light to identify a vessel, which is encompassed within the grasped tissue, receiving location information of the end effector from the location sensor, synchronizing a location of the identified vessel within the graphical representation based on the location information, and displaying the identified vessel at the synchronized location in the graphical representation.

System and methods for identifying vessels within tissue

A method of performing bariatric surgery using a robotic surgical system includes positioning a gastrectomy device in a selected location in a stomach; applying an adherent material to the stomach along a desired transection line; and cutting the stomach along the desired transection line delineated by the adherent material.
