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

A bipolar electrosurgical instrument includes first and second shafts each having a jaw member extending from its distal end. Each jaw member is adapted to connect to a source of electrosurgical energy such that the jaw members are capable of selectively conducting energy through tissue held therebetween. A knife channel is configured to reciprocate a cutting mechanism therealong. An actuator selectively advances the cutting mechanism. A switch is disposed on the first shaft and is configured to be depressed between a first position and at least one subsequent position upon biasing engagement with a mechanical interface disposed on the second shaft. The first position of the switch relays information to the user corresponding to a desired pressure on tissue and the at least one subsequent position is configured to activate the source of electrosurgical energy to supply electrosurgical energy to the jaw members.

Surgical forceps

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.

System and user interface for displaying actual operating parameters and ideal operating parameters

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

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.

Systems and methods for sealing and dissecting tissue using an electrosurgical forceps including a thermal cutting element

An end effector assembly includes a first jaw member having a first tissue contact surface and a second jaw member having a second tissue contact surface. The second jaw member is pivotally coupled to the first jaw member. The tissue contact surfaces may include raised steps that define an exhaust channel. A longitudinally extending knife slot may be defined in one or both of the tissue contact surfaces. One or more exhaust slots, which may be defined in one or both of the tissue contact surfaces, are in communication with the knife slot. The exhaust channel and the exhaust slots direct fluid away from the jaw members to minimize thermal damage risks associated with tissue sealing.

Electrosurgical instruments for controlling thermal damage

A combination patient return pad and surgical smoke evacuator includes a return electrode configured to attach to a surface and a suction tube for drawing surgical smoke from a surgical site.

Monopolar return pad including a pathway for evacuating surgical smoke

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 surgical instrument includes a housing, energizable member, first activation switch, cable assembly, and second activation switch. The housing is operatively associated with the energizable member. The first activation switch is coupled to the energizable member and is selectively transitionable from an open condition to a closed condition. The cable assembly is coupled to the housing at a first end and includes a plug at a second, opposite end, the plug housing a second activation switch selectively transitionable from an open condition to a closed condition. The plug is adapted to connect to the source of electrosurgical energy, wherein transitioning of the first activation switch from the open condition to the closed condition transitions the second activation switch from the open condition to the closed condition such that the second activation switch communicates with the source of electrosurgical energy to initiate the supply of energy to the energizable member.

Energy-activation mechanisms for surgical instruments

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.

Surgical instrument with resilient driving member and related methods of use

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 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 surgical instrument includes a housing having a first handle and an elongated shaft extending therefrom. An end effector is disposed at a distal end of the elongated shaft and includes first and second jaw members, the first jaw member including a staple cartridge configured to house a series of staples therein. A second handle is operably coupled to the housing and is selectively moveable relative to the first handle to actuate the first and second jaw members between an open position and a closed position for grasping tissue. A first switch is activatable to supply energy to one of the jaw members. A stapler mode switch is actuatable between an unactuated position wherein movement of the second handle moves the jaws to the second position and an actuated position wherein movement of the second handle moves the jaws to the second position and drives the staples through tissue.
