Various embodiments are configured to be operably attached to a robotic system to receive actuation/control motions therefrom.

A surgical treatment instrument includes an insertion portion including a longitudinal axis, an operation portion provided on one end side of the insertion portion, and a treatment portion provided on the other end side of the insertion portion and configured to treat a living tissue. The treatment portion includes a piezoelectric element configured to generate ultrasound and an ultrasound transmitting material configured to transmit the ultrasound generated by the piezoelectric element to the living tissue.

A robotic surgical system comprising a surgical instrument comprising an end effector comprising (i) a blade, (ii) a first jaw member including a first electrode, and (iii) a second jaw member including a second electrode. The robotic surgical system may also comprise a motor and a control circuit configured to: (i) produce control signals comprising a first control signal and a second control signal, (ii) deliver an electrosurgical energy signal to the first electrode and the second electrode via the first control signal, (iii) deliver a drive signal to the motor via the second control signal (iv) receive at least one feedback signal, (v) determine a rate of change based on a first feedback signal of the at least one feedback signal, and (vi) maintain the rate of change at a predetermined rate or within a predetermined range.

An ultrasonic surgical device including an elongate waveguide having a longitudinal axis and a distal end, and a blade extending away from the distal end of the waveguide, the blade including a curved portion that has at least five faces extending lengthwise along at least a portion of the length of the blade. Each of the faces has a width that extends perpendicular to the longitudinal axis of the waveguide and a length that extends orthogonal to the width. Each of the faces is flat across its width and is either flat along its entire length or includes one or more curved segments along its length, with each of the curved segments of an individual face being curved in the same direction. A method of fabricating an ultrasonic surgical device is also provided.

An ultrasonic-surgical and electrosurgical system includes an ultrasonic surgical device and an electrosurgical device which supply an ultrasonic signal and a high-frequency signal, respectively, to an ultrasonic/high-frequency treatment instrument capable of performing an ultrasonic treatment and a high-frequency treatment, and a relay device which is built in one of the devices including: a switch detection unit for detecting turn-on/off of a switch unit which performs on/off control of operations of the devices; a switch element for outputting a switch signal which is used for on/off of outputs of the ultrasonic signal and the high-frequency signal to each of the devices in accordance with the detection output; and a control unit for performing on/off control of the switch signal to control at least one of an output timing and an output mode of each of the signals.

A treatment tool includes a first gripping member, a second gripping member configured to be opened and closed with respect to the first gripping member, a heat radiating member and a first heat conductive member. A predetermined position between a closed state and an opened state is defined as a switching position in a process of changing the closed state to the opened state, a first region is defined as a region from the closed state to the switching position, and a second region is defined as a region from the switching position to the opened state. The first heat conductive member brings the first gripping member and the heat radiating member into a non-thermally contacted state in the first region, and brings the first gripping member and the heat radiating member into a thermally contacted state in the second region.

A computing system may predict a complication based on measurements of related biomarker(s) obtained via one or more sensing systems, and generate an adjustment of a surgical parameter associated with a surgery. The biomarker measurements may include pre-surgical and/or in-surgical measurements. The hemostasis-related biomarker(s) measured pre-surgery may include blood pressure, blood pH, edema, heart rate, blood perfusion rate, coagulation status and/or the like. Based on the prediction, the computing system may generate a control signal configured to alter a matter in which a surgical cutting and stapling device and/or a surgical energy operate, to adjust a surgical procedure plan, to adjust to a surgical instrument selection, indicate a probability of the hemostasis complication, and/or to indicate a suggested adjustment to surgical procedure plan, surgical approach, and/or surgical instrument selection.

Surgical devices and methods for utilizing optical coherence tomography (OCT) to monitor and control tissue sealing are disclosed. The surgical device includes an end effector assembly that includes first and second jaw members that are movable between a first, spaced-apart position and a second proximate position. An OCT system, at least a portion of which is incorporated into the end effector assembly, is configured to sense properties of the tissue, e.g., the structural density of the tissue, disposed between the first and second jaw members. A tissue-sealing energy source may be disposed within at least one of the jaw members and may provide tissue-sealing energy to tissue disposed between the jaw members. A controller, which is coupled to the OCT system and the tissue-sealing energy source, controls the tissue-sealing energy generated by the tissue-sealing energy source based on the properties of the tissue sensed by the OCT system.

An apparatus includes an interface assembly and a shaft assembly. The interface assembly is for use with a robotic system and includes a first drive assembly. The first drive assembly includes a first slot having a distal recess and a transverse recess. The shaft assembly is removably couplable with the interface assembly and includes an end effector and a first coupling feature. The first drive assembly of the interface assembly actuates the end effector of the shaft assembly. The first coupling feature is couplable with the first slot of the first drive assembly to longitudinally fix the shaft assembly relative to the interface assembly.

A method for removing tissues may comprise disposing a tissue resection device at a target tissue site, causing the tissue resection device to resect a core of tissue from the target tissue site, removing the core of tissue from the body, wherein the removing the core of tissue from the body creates a core cavity at the target tissue site.
