Background Technology
[0002] Aggressive cancer treatment is difficult because liver cancer invades blood vessels rapidly, grows quickly, and is usually accompanied by liver disease.
[0003] The treatment of liver cancer is divided into aggressive and conservative therapies depending on the stage and prognosis; however, conservative therapies are primarily used rather than aggressive ones to reduce complications associated with general anesthesia and resection.
[0004] Radiofrequency thermal ablation, a local cauterization technique in which a tumor is punctured with a needle and burned with heat under ultrasound guidance, is widely used as one of the conservative treatment methods. However, since it is difficult to achieve satisfactory results with a single treatment, there is a problem that repeated cauterization procedures are required. Prior art literature

[0020] As clearly illustrated in FIGS. 1, 2 and 5, the implantable bullet (1) is guided toward the malignant tumor (A) in vivo while connected to the instrument delivery gun (D) and implanted inside the tumor (A), and after implantation, as clearly illustrated in FIG. 6, the instrument delivery gun (D) is removed and the bullet remains inside the tumor (A).
[0021] As clearly illustrated in FIGS. 2 to 4, the in-body insertable bullet (1) comprises a tip portion (11), a main body portion (12), and a connecting portion (13).
[0022] The above-mentioned tip portion (11) is a part formed with a pointed tip so as to be able to enter the body, and the above-mentioned connecting portion (13) is a part provided on the opposite side of the tip portion (11) with the above-mentioned main body portion (12) in between and connected to a device delivery gun (D), and the above-mentioned main body portion (12) is a part provided between the tip portion (11) and the connecting portion (13).
[0023] The main body (12) is a part connected to the tip (11) and the connecting part (13), and receives energy from a power transmission part (B) outside the body (see FIG. 6; B) by means of electromagnetic induction, and utilizes the received energy as a power source to express optical energy in a malignant tumor (A). Here, while light sources of various wavelengths can be adopted as the optical energy, it is preferable to adopt UV-C to enhance the therapeutic effect.
