    摘要： An electrosurgical system comprising, among other things, a control console to which detachably connects one or more electrosurgical probes capable of coagulating and ablating tissue. The control console generates a selectively variable power signal having a duty cycle that is dynamically modulated so as to maintain an average power level of a probe that is lower than a predefined maximum power level. The system can also incorporate both an impedance monitoring system and a current monitoring system as means to detect potentially dangerous situations, as well as a monitoring system for detecting impedance at relatively low power levels upon first activation of the probe. The probe can also incorporate non-volatile memory for storing probe-specific operating parameter data, probe usage data, data restricting probe use, error codes, and control console updates.

    摘要： An electrosurgical tool for cauterizing or ablating targeted tissue, which tool includes a conductive outer shaft which defines a return or reference electrode, and a conductive inner tube disposed within the outer shaft. The inner tube defines both a suction pathway for removing fluid and/or surgical debris from the surgical site through the distal end of the tool, and a pathway for delivering electrical energy to an active electrode secured to the distal end of the suction tube.

    摘要： An LED based light source unit for an endoscopic imaging system produces illumination for a camera through an endoscope. The light source unit includes an array of LEDs mounted to a thermally conductive substrate, a light guide to collect light emitted from the LEDs and to couple the light into a group of optical fibers within the endoscope, and an interface to allow the light source unit to be removably attached to the endoscope at the endoscope's external light port. The LEDs therein may be overdriven by power for increased light output. When the LEDs reach their lifetime, the light source unit can be discarded.
