A surgical tool can include a handle, an outer tube, an end effector, an inner tube, and a guide tube. The outer tube can be connected to the handle and can extend along a longitudinal axis. The end effector can be connected to the outer tube. The inner shaft can be located within the outer tube and can extend along the longitudinal axis. The inner shaft can be connected to the end effector and the outer shaft. The handle can be operable to translate the inner shaft with respect to the outer tube to operate the end effector. The guide tube can be located within the outer tube between the handle and the end effector. The guide tube can include a conduit extending therethrough.

An arthroscopic system includes a re-useable, sterilizable handle integrated with a single umbilical cable or conduit. The single umbilical cable or conduit carries electrical power from a power and/or control console to the handle for operating both a motor drive unit within the handle and delivering the RF power to a disposable RF probe or cutter which may be detachably connected to the handle. The RF power delivered to the handle and on to the probe or cutter is typically bi-polar, where the handle includes first and second electrical bi-polar contacts that couple to corresponding bi-polar electrical contacts on a hub of the disposable RF probe or cutter is connected to the handle.

An electrosurgical forceps comprising: (a.) a pair of working arms comprising; (i.) a first working arm and a second working arm, each of the first working arm and the second working arm having an inner surface; (ii.) one or more electrodes located on the inner surface of the first working arm, the second working arm, or both; and (b.) a selectively engageable activation system comprising; (i.) a control unit; (ii.) an activation switch; and (iii.) a disengagement mechanism; wherein the first working arm and the second working arm are laterally movable relative to each other so that the activation switch is actuated when the disengagement mechanism is in an engaged position by closing the first working arm and the second working arm together, sending a signal to the control unit, which in turn sends a therapy signal to the one or more electrodes; wherein when the disengagement mechanism is in a disengagement position and the working arms are closed, the therapy signal is prevented from being sent from the control unit to the one or more electrodes.

Tissue treatment systems include an actuator handle assembly coupled with a clamp assembly having a first jaw mechanism and a second jaw mechanism. A first jaw mechanism includes a first flexible boot, a first flexible ablation member coupled with the first flexible boot, and a first rotatable jawbone disposed within the first flexible boot. A second jaw mechanism comprises a second flexible boot, a second flexible ablation member coupled with the second flexible boot, and a second rotatable jawbone disposed within the second flexible boot.

Present disclosure provides a cooling device with safety features and methods for controlling temperature of the cooling device for safe cooling of target surface.

An energy treatment tool includes: a grip to be held by an operator; a lever that is provided in a state of being exposed to an outside of the grip, the lever being configured to move in response to a changing operation by an operator, the changing operation being for changing an output state of energy; an electric switch that is arranged inside the grip the electric switch being configured to generate a signal for changing an output state of the energy; and a driver that is installed inside the grip such that the driver is rotatable about an axis intersecting an axis along a longitudinal axis correspondingly to movement of the lever, the driver being configured to switch the electric switch between a contacting state and a noncontacting state.

Aspects of the present disclosure include control systems of an electrosurgical system for managing the flow of fluid, such as saline, and rates of aspiration or suction, in response to various states of conditions at a surgical site. The control system(s) may monitor and adjust to impedance at the surgical site, temperature of the surgical tissue, and/or RF current of electrodes, and may account for certain undesirable conditions, such as the electrodes sticking. The control systems may include various automatic sensing scenarios, while also allowing for several manual conditions.

Medical devices including a housing, an actuator, a body having a passageway extending through the body, a drive shaft extending through the passageway, and a clip coupled to the body and the drive shaft to fix the body relative to the drive shaft. The medical device further including features to couple the clip to at least one of the body and/or the drive shaft such that back out of the clip is inhibited.

Forceps can include a drive pin, an outer tube, a first jaw, a second jaw, and an inner shaft. The outer tube can extend along a longitudinal axis. The first jaw can be pivotably connected to the outer tube. The first jaw can include a first flange that can be located at a proximal portion of the first jaw. The first flange can include a first chamfered edge configured to limit extension of the first flange laterally beyond an outer surface of the outer tube when the first jaw is in a closed position. The inner shaft can be located within the outer tube and can extend along the longitudinal axis.
