A device and an assembly method for assembling radioactive particle stents relate to the technical field of radiotherapy equipment for tumors. It includes a stand, a nail groove, a U-shaped nail, a positioning spring, a pressure handle, a particle rod clip, a spring leaf, a push rod, a return spring, a cover, a pin shaft, a nail pressing piece, and a pressure handle return spring. The device utilizes the principle of stapling, uses U-shaped nails to bind metal rods of radioactive particles used for tumor radiotherapy on the inner surface of the stent, and implants the stent into intraluminal tumor lesions such as esophageal cancer to realize the implantation of radioactive particles. radiation therapy. The device mainly includes a frame part, a particle rod pushing part, and a particle rod binding part. The three parts of the device work together to make the particle rod binding process simple, safe and efficient. The multi-position and individualized continuous assembly of the particle rod is realized, the operation efficiency and the safety of the treatment process of the radioactive particle interventional therapy are improved, and the cost of the treatment is reduced to a certain extent.
Description
technical field [0001] The invention relates to the technical field of radiotherapy equipment for tumors, in particular, an assembly device and an assembly method in a radioactive particle stent. The device can individually assemble the radioactive particles used for radiotherapy on the inner surface of the bearing bracket, and can realize fast and safe assembly of the radioactive particles. Background technique [0002] Radiation therapy is one of the main methods for the clinical treatment of malignant tumors. The types of radiation therapy are mainly divided into two types: external radiation therapy and brachytherapy. For a long time, external radiation therapy has been the main way of radiation therapy. After the 1980s, due to low-energy nuclides 125 I and 103 The successful development of Pd, etc., the emergence of computer three-dimensional treatment planning system and the development of implantation technology guided by B-ultrasound, CT, MRI, etc., have opened up...
