Target radiofrequency ablation system

Abstract

The invention provides a target radiofrequency ablation system which comprises an irradiation head, an infrared thermometer, a lymph node tracer agent and a center control system. The center control system comprises a laser wavelength control unit, a temperature monitoring unit and a warning unit. Based on a photothermal effect and photothermal treatment of tumors, by combination with the characteristics of high photothermal conversion efficiency of dyes, the target radiofrequency ablation system is used for treatment of superficial organ tumor lymphatic system transfer to achieve the goal of reducing local recurrence, and an effect of radiotherapy on lymphatic metastasis is supplementing and even replaced to a certain extent. The target radiofrequency ablation system is high in safety, including safety of an injection material and laser. The target radiofrequency ablation system is simple and convenient in process and low in cost. After an operation, short-time laser irradiation is performed every day, a patient's wound healing is not affected, the patient's pain is not increased, and only a little cost is increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a targeted radiofrequency ablation system. Background technique [0002] The incidence of breast cancer has been increasing year by year, and its incidence has ranked first among female malignant tumors. It is one of the major diseases that seriously threaten women's health. Lymph node metastasis is the main way of breast cancer metastasis. Traditional breast cancer surgery mainly involves complete resection of breast glands, removal of subcutaneous lymphatic network as much as possible (thin skin flap, no matter how thin, it is impossible to completely remove subcutaneous lymphatic network), and cleaning of axillary lymph nodes, even lymph nodes above and below the clavicle or parasternal Lymph node dissection, if the dissected lymph node metastasis reaches more than 4, the mass is larger than 5 cm, and the tumor is located in the inner side, radiotherapy is required to...

Problems solved by technology

[0005] However, the radiotherapy performed by the above-mentioned or existing radiofrequency ablation system has no targeting, and can cause a certain degree of damage to the irradiated part, so there are many side effects: radiation dermatitis, radiation pneumonitis, radiation esophagitis, radiation pericarditis etc., seriously damage the health of patients, and it is also very difficult for clinicians to deal with it.

[0006] At present, there is no report on targeted therapy for the treatment of lymphatic system metastasis of superficial organ tumors (such as breast cancer, thyroid cancer, penile cancer, and melanoma)
