技术领域technical field

背景技术Background technique

射频(微波)消融治疗是近年来肝癌治疗的重要进展之一,是肝癌微创治疗的代表性治疗方式。原理是通过电流使肿瘤组织中粒子产生振荡发热,从而达到凝固损毁肿瘤的目的,其对肝功能损害小,对病人体质要求低。Radiofrequency (microwave) ablation is one of the important advances in the treatment of liver cancer in recent years, and it is a representative treatment method for minimally invasive treatment of liver cancer. The principle is to make the particles in the tumor tissue oscillate and generate heat through electric current, so as to achieve the purpose of coagulation and damage to the tumor. It has little damage to liver function and low physical requirements for patients.

所有射频热消融垂堑均由电发生器、测控单元、电极针、皮肤电极和计算机五部分组成。通过监控肿瘤组织的阻抗、温度等参数的变化,调节射频消融的输出功率,借助于超声或CT等影像技术引导,也可在腔镜下或手术直视下将电极针直接插入肿瘤内,通过射频能量使病灶局部组织产生高温、干燥,局部温度可达100℃以上,导致肿瘤组织凝固性坏死,从而达到彻底灭活肿瘤目的。All radiofrequency thermal ablation verticals are composed of five parts: electric generator, measurement and control unit, electrode needle, skin electrode and computer. By monitoring the changes of tumor tissue impedance, temperature and other parameters, adjusting the output power of radiofrequency ablation, with the help of imaging technology such as ultrasound or CT, it is also possible to insert the electrode needle directly into the tumor under the laparoscope or under direct vision of the operation. The radiofrequency energy makes the local tissue of the lesion generate high temperature and dryness, and the local temperature can reach above 100°C, leading to coagulation necrosis of the tumor tissue, so as to achieve the purpose of completely inactivating the tumor.

目前现有的射频消融装置大多通过注射的方式将电极针插入到患者体内肿瘤中,而后利用胶带粘贴在皮肤上,但是在粘贴的过程中必然会对插入到肿瘤内的电极针施力,极易造成电极针与肿瘤脱落。At present, most of the existing radiofrequency ablation devices insert the electrode needle into the tumor in the patient's body by injection, and then stick it on the skin with adhesive tape. It is easy to cause the electrode needle and the tumor to fall off.
