Description

Implantable optical device for treating malignant tumors

[0001] The present invention relates to an implantable optical device for treating malignant tumors, and more particularly, to an implantable optical device for treating malignant tumors having an improved structure that allows repeated treatment by receiving energy from outside the body and generating optical energy while inserted into a tumor without requiring an incision or invasive treatment.

[0002] Liver cancer is not easy to treat actively because it invades blood vessels and grows rapidly, and is often accompanied by liver disease.

[0003] Treatment for liver cancer is divided into active treatment and conservative treatment depending on the stage and prognosis. Conservative treatment is mainly used rather than active treatment to reduce the complications of general anesthesia and resection.

[0004] Among conservative treatments, radiofrequency ablation, a local ablation procedure that involves burning the tumor with heat by inserting a needle under ultrasound guidance, is widely used. However, it is difficult to achieve satisfactory results with a single treatment, so repeated ablation procedures are required.
