Số lượng năng lượng được sản xuất mỗi giây, được thể hiện trong watt. Chất liệu thực hiện dòng điện. HF phẫu thuật cắt bỏ thủ tục trong phụ khoa, một vòng lặp được sử dụng để loại bỏ các vùng chuyển đổi của cổ tử cung (cắt bỏ vòng lặp lớn của vùng chuyển đổi). Macro sóng HF phẫu thuật chế độ lưỡng cực được sử dụng trong phẫu thuật | 53 5 Glossary Power Conductor LLETZ LEEP Quantity of energy produced per second expressed in watt. Material which conducts electric current. HF surgical excision procedure in gynaecology where a loop is used to remove the transformation zone of the cervix large loop excision of the transformation zone . Macro bipolar HF surgical wave mode used in bipolar surgery with higher voltage and power than the normal bipolar HF surgical wave modes. It is used for bipolar incision or fast coagulation. Micro bipolar Monopolar HF surgery Bipolar wave mode with low voltage used for precise desiccation. HF surgery procedure where the active electrode is in the surgical wound. One active pole. Monopolar output Earthed or insulated output for a HF surgical device which conducts current through the patient to the neutral electrode. Monopolar instrument HF surgical instrument or accessory consisting of just one electrode one active electrode. Necrosis Neutral electrode Destruction of tissue. Conductive surface in direct contact with the patient s skin during HF surgery. During the operation it absorbs the HF current from the patient across a wide surface distributes it and returns it to the HF surgical device closing the circuit. Standard neutral electrodes today are disposable electrodes fixed with an adhesive gel. Ohm Q Unit of measurement for electrical resistance volt per ampere. REM contact quality monitoring system Special Valleylab safety system which continuously monitors the impedance Incision level between patient and neutral electrode. If the REM system registers dangerous impedance levels as a result of poor contact between the neutral electrode and the patient the system produces an acoustic and optical signal and the HF surgical device is switched off. To guarantee maximum safety HF surgical devices equipped with REM must use a compatible neutral electrode. This electrode can be recognised as having two separate areas and a special connector with a middle pin. HF .
