Definitions

• the invention relates to a surgical instrument, in particular electrosurgical instrument. Furthermore, the invention relates to a use of a FRAM memory device.
• electrosurgical instruments are used, for example, in electrosurgical coagulation and / or ablation of biological tissue.
• electrodes of the instrument with a high-frequency voltage (RF voltage) under defencel potential (bipolar) applied, so that the tissue surrounding the electrodes is heated so far, thereby denaturing the body's own proteins.
• a high-frequency alternating current is passed through tissue to be treated surgically in order to specifically damage or cut it.
• Technique is carried out simultaneously with the cut a hemostasis by closure or desolation of the affected vessels.
• an electrode is used instead of a scalpel, which is attached to a surgical instrument, such as a resectoscope.
• An electrosurgical system often includes an RF generator with a capability of several hundred watts and an operating voltage of 1000 volts or more.
• An RF signal generated by the RF generator is applied to the RF electrode.
• one terminal of the high voltage output is connected to the RF electrode.
• the second port is brought into contact with a large area patient electrode.
• the current used for treatment flows through the patient back to this patient electrode.
• the RF electrode used for treatment comprises two poles between which the current generated by the RF generator flows.
• a plasma forms on the HF electrode, which effects the medical treatment, that is to say cutting action and / or coagulation.
