In an energy control device, a processor detects, based on a detection result of an electric characteristic value in relation to an electric energy which is output from an energy output source to an ultrasonic transducer, a gradual decrease start time at which the electric characteristic value starts a gradual decrease after a gradual increase. The processor executes, based on a fact that a time rate of change of the electric characteristic value become greater than a predetermined threshold after the gradual decrease start time, at least one of causing the energy output source to stop or reduce the output of the electric energy to the ultrasonic transducer, and notifying that the time rate of change become greater than the predetermined threshold.

The present disclosure provides an endoscopic surgery apparatus that includes an insertion tube having a passage formed inside, and that is to be inserted into a patient's urethra; a laser part that is installed such that it can reciprocate in the passage, and that separates a prostate adenoma from a patient's prostatic capsular surface; a hemostasis part that is installed such that it is spaced apart from the laser part and can reciprocate in the passage, and stops bleeding of a bleeding blood vessel of the patient's prostatic capsular surface; a camera part that is located in the passage and that photographs inside of the patient's prostate; and a transfer part that selectively transfers the laser part and the hemostasis part.

An electrosurgical system includes an RF current generator, a handle body, and an end effector. The end effector may include a first and a second energy delivery surface. At least a portion of either first or second energy delivery surfaces, or both, may include one or more patterned coatings of an electrically non-conducting non-stick material. The material may be deposited on a surface of, within a depression in, or on features extending from the energy surfaces, or through an overmolding process. The patterned coating may be formed from a coating of the material from which portions have been removed. An energy delivery surface has a first area, and the patterned coating has a second area. A ratio of the second area to the first area may be less than or equal to about 0.9, less than or equal to about 0.7, or less than or equal to about 0.5.

A tissue resecting device includes an outer sleeve having an axial bore extending along a longitudinal axis from a proximal end to a distal end and opening to an outer window near the distal end. An inner sleeve is rotatably received in the axial bore of the outer sleeve and has an axial channel adapted for communication with a negative pressure source. A distal housing is attached to a distal end of the inner sleeve and has an annular dielectric portion and a circumferentially adjacent annular metal portion having an inner window with circumferentially spaced-apart sharp cutting edges that opens to the axial channel. An active electrode is carried by the annular dielectric portion, and the inner window is circumferentially spaced-part from the active electrode so that the inner window and the active electrode rotate alternately into alignment with the outer window as the inner sleeve is rotated within the outer sleeve.

A heater is configured to be coupled to the blade. The heater includes respective first and second heat generating surfaces each of which extending in a direction transverse to the treatment surface. Respective first and second thermally conductive members each of which is interposed between the respective first and second heat generating surfaces and the blade so as to thermally engage the respective first and second heat generating surfaces and the blade to one another. The respective first and second thermally conductive members includes respective first and second thermal conductivity anisotropies each of which being higher in longitudinal directions of the blade and each of which being lower in widthwise directions of the blade that are transverse to the longitudinal directions.

A method of compressing tissue during a surgical procedure is disclosed. The method comprises obtaining a surgical instrument comprising an end effector, wherein the end effector comprises a first jaw and a second jaw, establishing a communication pathway between the surgical instrument and a surgical hub, and inserting the surgical instrument into a surgical site. The method further comprises compressing tissue between the first jaw and the second jaw, determining a location of the compressed tissue with respect to at least one of the first jaw and the second jaw, communicating the determined location of the compressed tissue to the surgical hub, and displaying the determined location of the compressed tissue on a visual feedback device.

Various embodiments provide an electrosurgical resector tool comprising: a shaft defining a lumen; an energy conveying structure for carrying electromagnetic (EM) energy through the lumen of the shaft; an instrument tip mounted at a distal end of the shaft. The instrument tip comprises: a static portion comprising a first blade element; and a movable portion comprising a second blade element, wherein the movable portion is movable relative to the static portion between a closed position in which the first blade element and second blade element lie alongside each other to an open position in which the second blade element is spaced from the first blade element by a gap for receiving biological tissue. The instrument tip also includes a travel limiting mechanism operable to limit a maximum extent of relative movement between the second blade element and the first blade element in the open position and/or the closed position.
