摘要
An electrosurgical apparatus having a HF power source providing HF energy for electrosurgery and a circuitry to control application of said HF energy to an electrode end used in electrosurgically operating on a patient is characterized in that said circuitry is adapted to apply in a dissecting mode said HF energy for dissecting to an electrode end automatically in the form of pulses such that the pulses automatically have a defined length. This device can be used for exploration of the bladder and en bloc radical removal of a large tumor using the active resection electrode loop of an optic resectoscope such that the bladder wall layers below the tumor base within the intact tissue margin are prepared using step-by-step coagulation and dissection of the tumor nutrient vessels and of the interlayer tissue fibers performed by impulsive turns-on of the electrosurgical apparatus in-use in the monopolar dissection mode.
