A fluid source on a carrier is configured to rotate relative to a probe to direct a fluid stream from the source toward an opening of an evacuation lumen. This may help to remove material that may collect near the opening, such as blood clots and tissue. Also, directing the fluid stream toward the evacuation lumen can draw flowable material from the surgical site toward the evacuation lumen to improve removal of material from the surgical site.

A surgical system comprising: a plurality of modular units, each unit comprising: a motor unit; and a surgical mechanical arm actuated by, connected to and supplied with electrosurgical power by the motor unit; and a memory configured to store a selected electrosurgical operational mode for each of the plurality of modular units.

A surgical instrument system comprising a first motor, a second motor, and a third motor is disclosed. The surgical instrument system comprises a first handle comprising a first number of controls, a second handle comprising a second number of controls, and a shaft assembly. The shaft assembly is attachable to the first handle in a first orientation in order to engage one of the motors. The shaft assembly is attachable to the second handle in a second orientation to engage a different motor. The surgical instrument system is configured to perform a different function of an end effector in the first orientation and the second orientation.

An electrosurgical probe includes an elongated shaft assembly having a proximal end, a distal end, and a longitudinal axis. A distal housing is mounted on the distal end of the shaft and optionally includes a laterally open window where a plane of the window is generally perpendicular to the longitudinal axis of the shaft. An interior channel extends axially through the shaft and further through an interior of the housing to the window in the housing. An electrode member with a serrated or other elongated edge may extend longitudinally across the window and may be configured to reciprocate the elongated edge longitudinally relative to the window.

An arthroscopic tissue resecting probe includes an elongated shaft having outer and inner sleeves which are formed from an electrically conductive material extending about an axis to a working end. Outer and inner resecting windows are formed in the sleeves in the working end. The working end includes a ceramic body having a collar portion extending fully around a region of the outer sleeve proximal to outer resecting window. A radiofrequency (RF) electrode is disposed on an outer surface of the ceramic body and is spaced-apart from the outer resecting window.

Provided is a high frequency hyperthermia device which includes a main body (110) which includes a high frequency generator (114) which generates high frequency currents using drive power, a hand piece (120) which is connected to the main body (110) through a cable (140) and in which a handle (121) to be gripped by a user is disposed on an upper portion of the hand piece (120), and four or more contact electrodes (122), through which the high frequency currents being supplied are applied to skin (S) in contact with the contact electrodes (122) to generate deep heat in an internal body, are disposed on a lower surface of the hand piece (120), and an alternating switch (130) which is disposed between and connected to the high frequency generator (114) and the contact electrodes (122) in a circuit manner and which supplies the high frequency currents output from the high frequency generator (114) to the contact electrode (122), wherein the contact electrodes (122) are divided into pairs each having two contact electrodes (122), and the high frequency currents are alternately supplied to the pairs at a first speed.

An arthroscopic cutter according to one embodiment of the present disclosure includes an elongated outer sleeve that extends about a longitudinal axis with an interior bore having an open distal end. An inner sleeve is rotatable in the interior bore in the outer sleeve. The inner sleeve carries a distal housing having a longitudinal metal member and a longitudinal ceramic member that respectively form longitudinal-extending sides of the housing around an inner channel that communicates with a negative pressure source. The arthroscopic cutter also includes an electrode that is disposed in an outer surface of the longitudinal ceramic member.

A control handle of a treatment probe is manipulated to advance and/or deploy one or more treatment structures into tissue. The treatment probe is coupled to a display to show an image field including target tissue for treatment. Virtual treatment and safety boundaries are overlaid over the image field. The boundaries include virtual stop positions for the needle and tines. A joystick or directional pad on the probe handle, operable independently from the user interface to advance and/or deploy the one or more treatment structures, can be manipulated to adjust the size and/or position of these boundaries. Sensors within the probe detect the real-time position of the one or more treatment structures, and the sensed positions are displayed in real-time. The user can observe the display to deploy the one or more treatment structures to the displayed virtual stop positions.

An arthroscopic cutting probe includes a shaft assembly having a distal end, a proximal end, and a longitudinal axis. A distal cutting member is rotatably attached at the distal end of the shaft assembly, and at least a portion of an exterior surface of the distal cutting member is electrically insulated. One or more burr elements extend radially outwardly from the electrically insulated portion of the exterior surface of the distal cutting member, wherein the burr element is electrically conductive to form an active electrode.

A robotic surgical instrument comprising a shaft, an end effector, and an articulation connecting the end effector to a distal end of the shaft. The articulation comprises joints permitting the end effector to adopt a range of orientations relative to a longitudinal axis of the shaft. Pairs of driving elements drive the joints, the driving elements extending through the shaft to the joints. An additional element extends through the shaft to the end effector via the articulation. A resilient barrier inside the shaft extends over a cross-sectional area of the shaft, the pairs of driving elements and the additional element passing through the resilient barrier, the resilient barrier being in resilient contact with the additional element so as to provide a resilient force opposing movement of the additional element; wherein each driving element of the pairs of driving elements passes through a hole in the resilient barrier without contacting the resilient barrier.
