A robotic system includes an electrosurgical instrument having an instrument housing having a shaft with an end effector assembly and first and second jaw members attached thereto movable to grasp tissue. An input is operably coupled to the instrument housing and is configured to move the jaw members. A handle is remotely disposed relative to the instrument housing and is configured to communicate with the input for controlling the jaw members, the handle having a lever configured to cooperate with the input to control the jaw members relative to movement of the lever. The lever moves between a homing position and a first position correlating to the jaw members closing with a pressure therebetween in the range of about 0.1 kg/cm.sup.2 to about 2 kg/cm.sup.2. The lever further movable to a seal position correlating to the jaw members closing about tissue with a pressure between about 3 kg/cm.sup.2 to about 16 kg/cm.sup.2 for sealing.

An electrosurgical device having an electrode with a first portion whose exterior is electrically uninsulated, a second portion whose exterior is electrically insulated, and a third portion. An elongated hollow body has an internal cavity, a front end, a rear end, an external surface. An electrical circuit is arranged within the body. The second portion of the electrode is not surrounded by the hollow body. A first button is arranged on the external surface of the body for controlling a current flow at a first level. A vacuum tube is slidably engaged by the body. A vacuum outlet port is arranged near the rear end, and the outlet port, internal cavity, and vacuum inlet are in fluid communication with each other.

An apparatus comprises a first jaw, a second jaw, a first handle, and a second handle. The second jaw is pivotally coupled with the first jaw. The first jaw and the second jaw are configured to grasp tissue. The jaws provide offset electrode surfaces that are operable to deliver bipolar RF energy to tissue grasped between the jaws. The apparatus is further operable to sever tissue. A lockout feature selectively prevents tissue severing, based on an energization state of the jaws.

A control device (1) for an electrosurgical instrument (2), in particular a high-frequency sealing instrument, including a fixed handle part (3), a movable handle part (4), an activation element (5) for activating a current flow, in particular a first type, preferably a sealing current, wherein the activation element (5) is or can be adjusted between a deactivation position and at least one activation position when the movable handle part (4) is actuated, wherein, when the movable handle part (4) is actuated, the activation element (5) is or can be adjusted about an axis of rotation (7).

A device for controlling the energy supply to a medical instrument contains the medical instrument and an energy supply device. The energy supply device has at least a first and a second energy supply mode that can be preselected on the energy supply device and which supplies energy to the medical instrument according to a preselected energy supply mode. The energy supply device additionally has a third mode which differs from the at least two energy supply modes, can be preselected on the energy supply device, can detect an actuation of an energy supply operating element arranged on the medical instrument, and can carry out the supply of energy to the medical instrument in the first or second mode based on the detected actuation.

A surgical instrument connectable to a surgical energy module that is configured to provide a first drive signal at a first frequency range for driving a first energy modality and a second drive signal at a second frequency range for driving a second energy modality is provided. The surgical instrument can comprise a surgical instrument component configured to receive power from a direct current (DC) power source, an end effector, and a circuit. The circuit can be configured to convert the first electrical signal to a DC voltage, apply the DC voltage to the surgical instrument component, and deliver the second energy modality to the end effector according to the second drive signal. Alternatively, the circuit can be disposed within a cable assembly configured to connect the surgical instrument to the surgical energy module.

An instrument including working arms and a moveable member. The working arms include a first arm, a second arm, a first electrode located on the first arm, and a second electrode located on the second arm. The moveable member includes a passive circuit element, a first terminal, and a second terminal. The moveable member is moveable to a first position and a second position. In the first position, the first terminal is in electrical communication with the first electrode and the second terminal is in electrical communication with the second electrode so that in the first position an electrical circuit is completed. An impedance is measured of the passive circuit element in the completed electrical circuit. The instrument is adapted to provide a modality based on the measured impedance or a determined position of the moveable member.

A method of controlling a function of a surgical instrument of a surgical robot with a input of a user interface includes selecting a function of a surgical instrument to link a input of the user interface with the function of the surgical instrument, actuating the input to activate the function of the surgical instrument, and delinking the input from the surgical instrument in response to an event of the surgical robot or the user interface.

An electrosurgical instrument (1) includes a first shaft member (110) pivotably coupled to a second shaft member (120), and a trigger (184) disposed on the second shaft member (120). The first and second shaft members (110,120) respectively include first and second handle members (130,140), and first and second jaw members (150,160). The first and second shaft members (110,120) define a longitudinal axis extending through a pivot, and first and second pivot axes that are substantially orthogonal to each other and the longitudinal axis. At least one of the first or second handle members (130,140) is pivotable about the first pivot axis to move the first and second jaw members (150,160) to an open position, a grasping position, or a sealing position. The trigger (184) is movable to pivot at least one of the first or second shaft members (110,120) about the second pivot axis to laterally displace the first and second jaw members (150,160) relative to each other to a cutting position.

An ultrapolar electrosurgery blade and an ultrapolar electrosurgery pencil. The ultrapolar electrosurgery blade has a non-conductive planar member with opposing planar sides, a cutting end, and an opposite non-cutting end, first active and return electrodes located on one opposing planar side, and second active and return electrodes located on the other opposing planar side.
