技术领域technical field
本发明涉及医疗器械技术领域，具体涉及一种低温等离子体手术电极。The invention relates to the technical field of medical instruments, in particular to a low-temperature plasma surgical electrode.
背景技术Background technique
现在临床上大规模使用电外科设备进行手术治疗，电外科设备包括高频手术刀、射频手术刀和离子手术子刀。高频手术刀由于手术电极高热，过薄或过细的电极，其机械强度不足以支持手术的完成，因此现有高频手术刀的电极较粗，造成切割人体组织较宽的切口，温度很高对于周边组织热损伤很大，不适合精细手术的要求。低温等离子手术刀则采用低温消融技术，利用100KHz射频电场的高能量特性，使电极和组织间形成等离子薄层，该薄层中离子被电场加速后将能量传递给组织并在低温(40-70℃)下打开细胞间分子结合键，从而进行组织的切除、消融、止血，大大减轻组织的损伤和病人的痛苦并缩短康复周期。目前低温等离子电刀，多采用单极电极，起到切割和止血的作用。单极电极工作极和回路极相互分离，工作极治疗病灶，回路极以电极板的方式贴于患者皮肤因此电流会流经人体，存在安全隐患。Now clinically, electrosurgical equipment is used on a large scale for surgical treatment. Electrosurgical equipment includes high-frequency scalpel, radiofrequency scalpel and ion surgical knife. Due to the high heat of the surgical electrode, the mechanical strength of the electrode that is too thin or too thin is not enough to support the completion of the operation. Therefore, the electrode of the existing high-frequency scalpel is relatively thick, resulting in a wide incision for cutting human tissue, and the temperature is very high. The thermal damage to the surrounding tissue is very large, and it is not suitable for the requirements of fine surgery. The low-temperature plasma scalpel adopts low-temperature ablation technology, and uses the high-energy characteristics of 100KHz radio frequency electric field to form a thin plasma layer between the electrode and the tissue. The ions in the thin layer are accelerated by the electric field and then transfer energy to the tissue. °C) to open the intercellular molecular bonds, thereby performing tissue resection, ablation, and hemostasis, greatly reducing tissue damage and patient pain and shortening the recovery period. At present, low-temperature plasma electrosurgical units mostly use monopolar electrodes, which play the role of cutting and hemostasis. The working electrode and the return electrode of the unipolar electrode are separated from each other, the working electrode treats the lesion, and the return electrode is attached to the patient's skin in the form of an electrode plate, so the current will flow through the human body, which poses a safety hazard.
