Ultrapolar telescopic electrosurgery pencil with argon beam capability which is capable of using monopolar energy in a bipolar mode for cutting and coagulation and which is also capable of using an ionized gas for cutting and coagulation.

Described here are methods and systems for the manipulation of ovarian tissues. The methods and systems may be used in the treatment of polycystic ovary syndrome (PCOS). The systems and methods may also be useful in the treatment of infertility associated with PCOS.

An ultrapolar electrosurgery blade assembly for use in ultrapolar telescopic and non-telescopic electrosurgery pencils with argon beam capability. The ultrapolar electrosurgery blade assembly includes a non-conductive planar member having opposing planar sides and a sharp cutting edge, a return electrode located on one opposing planar side, an active electrode located on the opposite planar side, and a non-conductive hollow tube member positioned over a top of the non-conductive planar member such that it is in physical contact with at least a portion of the return electrode located on one of the opposing planar sides of the non-conductive planar member.

Surgical systems are disclosed. Surgical systems can include evacuation systems for evacuating smoke, fluid, and/or particulates from a surgical site. A surgical evacuation system can be intelligent and may include one or more sensors for detecting one or more properties of the surgical system, evacuation system, surgical procedure, surgical site, and/or patient tissue, for example.

Various systems and methods for controlling an ultrasonic surgical instrument according to the location of tissue grasped within an end effector are disclosed. A control circuit can be configured to apply varying power levels, via a generator, to an ultrasonic transducer driving an ultrasonic electromechanical system to oscillate an ultrasonic blade. Further, the control circuit can measure impedances of the ultrasonic transducer corresponding to the varying power levels and determine a location of tissue positioned within the end effector according to a difference between the impedances of the ultrasonic transducer relative to a threshold.

An ultrasonic electromechanical system for an ultrasonic electromechanical system may include an ultrasonic blade, a clamp arm disposed opposite the ultrasonic blade, an ultrasonic transducer acoustically coupled to the ultrasonic blade, in which the ultrasonic transducer is configured to oscillate the ultrasonic blade in response to a drive signal, and a control circuit coupled to the ultrasonic transducer. The control circuit can be configured to determine a position of a tissue clamped between the ultrasonic blade and the clamp arm, and control an amount of power of the drive signal based at least in part on the position of the tissue.

A surgical instrument that includes a surgical end effector that is articulatable relative to a proximal shaft segment of the surgical instrument. The surgical end effector is attached to the proximal shaft segment by an articulation joint that comprises a plurality of movably interconnected links that interface with a centrally disposed drive member to apply articulation motions thereto and which serve to provide improved lateral stability to the articulation joint.

A surgical system comprising a generator and a surgical instrument configured to receive power from the generator is disclosed. The surgical instrument comprises a housing, a shaft defining a longitudinal axis, an end effector, and an internal charge accumulator. The housing comprises a motor. The end effector is operably responsive to actuations from the electric motor, transitionable between an open and closed configuration, and rotatable about an articulation axis transverse to the longitudinal axis. The generator is incapable of supplying a sufficient power directly to the motor to perform the actuations. The internal charge accumulator is in electric communication with the generator and supplies power to the motor. The internal charge accumulator is chargeable by the generator to a threshold value at a charge rate dependent on a charge level of the internal charge accumulator. The charge rate is independent of a charge expenditure by the surgical instrument.
