Abstract

The invention belongs to the technical field of particle implantation, and discloses a limit device for improving axial accuracy of a particle implanting needle. The limit device comprises a positioning cap, a main lumen tube and a needle tube. One end of the main lumen tube is detachably connected with a positioning cap, the other end of the main lumen tube is communicate with a needle tube, andthe positioning cap is connected with a positioning assembly at one end away from the main lumen tube, and the outside of the needle tube is provided with a scale mark. As the limiting device for improving axial accuracy of a particle implanting needle sets the positioning assembly, the positioning assembly can not only detect the angular deviation of the implantation needle, but also detect the axial accuracy of the implantation needle, so as to ensure that each particle can be implanted into a predetermined area.

Description

technical field [0001] The invention belongs to the technical field of particle implantation, and in particular relates to a limiting device for improving the axial precision of a particle implantation needle. Background technique [0002] The full name of seed implantation is "radioactive seed implantation therapy", which is a treatment method that implants a radioactive source into the tumor to destroy the tumor. The particle implant therapy technique involves a radioactive source, the core of which is radiating particles. Now clinical use is a substance called iodine 125. Each iodine-125 particle is like a small sun, with the strongest rays near the center, minimizing damage to normal tissues. Particle implant therapy can be traced back to the beginning of the last century. At present, radioactive seed implantation has become a standard treatment for early prostate cancer in the United States and other countries, and its treatment concept has gradually been recognized ...
