Radioactive particle loader

Abstract

The invention discloses a radioactive particle loader. The radioactive particle loader comprises an elastic fixing part, a mounting part and a radioactive particle strip, wherein the elastic fixing part is of a tubular structure with a through hole; the mounting part is arranged on the elastic fixing part; the radioactive particle strip comprises a particle tube clamped in the mounting part and radioactive particles filled in the particle tube; and the elastic fixing part is arranged on a drainage tube or a bracket through the through hole in a sleeving mode. The radioactive particle loader has the advantages that the radioactive particle strip is clamped on the elastic tube, and the elastic tube can be arranged on drainage tubes or brackets with different specifications and different types in a sleeving mode, so that the loader can be suitable for radioactive treatment of different tumors and is wide in application range; the drainage tube is placed in the body of a patient through puncture, so that radioactive particles can be implanted, and the operation is simple; the length of a mounting groove is smaller than that of the particle tube, and limiting blocks at the two ends of the mounting groove can limit the particle tube filled with radioactive particles; and the contact surface between the particle tube and the limiting blocks is a concave-convex connecting surface, so that the fixing effect of the particle tube is further ensured.

Description

technical field [0001] The invention relates to medical equipment, in particular to a radiation particle loader used in radiation particle implantation. Background technique [0002] Radiation seed implantation is guided by images such as X-rays, CT or ultrasound, and directly implants iodine-125 particles emitting low-energy rays into the tumor tissue for continuous radiation damage to the tumor tissue. At present, radiation seed implantation has the advantages of small internal radiation dose, accurate treatment positioning, high local dose to tumor, small radiation radius, and less damage to surrounding normal tissues, etc., and has been widely used clinically. [0003] At present, the radioactive particles are generally encapsulated in the particle tube directly in clinical practice, and then the particle tube is directly implanted into the tumor tissue of the patient. However, the fixation effect of the particle tube is poor, and it is easy to come out during the treat...

Problems solved by technology

However, the types of drainage tubes with radioactive particles in the existing market are extremely limited, and the clinical conditions are various, and the corresponding types of drainage tubes are also diverse. It is difficult to improve only a few drainage tubes to meet the needs of tumor tissues in different parts. radiation therapy needs
