Description

A kind of radioactive seed loader

Technical field:

This utility model relates to and a kind of radioactive particle is implanted to radioactive particle implantation device on the human body, particularly relates to a kind of radioactive seed loader.

Background technology:

Adopt radioactive particle to be used widely in clinical in direct implantable brachytherapy treatment tumor technology between tissue, wherein, the implantation device of radioactive particle is indispensable instrument, and implantation device mainly comprises particle delivery device, grain source loader and puncture needle; In the process of particle implanted treatment tumor, backflow to implanting gun through puncture needle because cancer is hemorrhage, in implanting gun, form sludged blood and particle bonding rapidly, make particle source can't be pushed into the phenomenon in precalculated position glibly, be called " Ka Yuan "; In case taking place, Ka Yuan will seriously incur loss through delay operation process, remove the method for this technology barrier, normally disassemble implanting gun, cleaning removes blood clot, the particle of reloading, after Ka Yuan takes place, any particle source that makes is directly exposed to the unnecessary radiation injury that the outer process of ray-proofing device must increase the medical worker, add that common particle source itself had only 4.5 millimeters long, diameter 0.8 mm wide does not load under the specific purpose tool platform and is very easy to lose, operate not only difficulty but also time-consuming, in addition, because magazine or cartridge clip are lighttight material manufacture, particle source is omitted and is difficult to find in operation process.Therefore, research a kind of can overcome card source phenomenon and convenient, fast, safe particle implantation device particularly grain source loader be that this area scientific and technical personnel expect the problem that solves.

The utility model content:

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of radioactive seed loader that helps to overcome card source phenomenon is provided.

The purpose of this utility model is achieved in that a kind of radioactive seed loader, comprise the housing 2 that is provided with magazine 1, pressing pole 3, spring 4 and top cover 5, described pressing pole 3 bottoms are thick portion 3.1, top is thin portion 3.2, be boss structure, can move up and down along magazine 1, have the through hole 6 that thin portion 3.2 cross sections with pressing pole 3 are complementary in the middle of the described top cover 5, the periphery of top cover 5 is provided with and the housing 2 tops bayonet socket 7 of clamping mutually, described spring 4 is placed in the thin portion 3.2 of pressing pole 3, spring upper end 4.1 is connected with top cover inner surface 5.1, spring lower end 4.2 places the thick upper surface 3.1.1 of portion of pressing pole 3, the square-section of described magazine cross section for holding radioactive seed 8, described housing 2 is before magazine 1 bottom, respectively have a through hole 9 that the center is symmetrical on the symmetric pair of sidewalls 1.1 in back, the diameter of the diameter of through hole 9 and every radioactive seed 8 is complementary, and described housing 2 bottoms have a cleanout fluid hand-hole 10.

Described housing 2 is transparent or semitransparent medical plastic manufacturing.

The beneficial effects of the utility model are: owing to use technical scheme described in the utility model, particularly housing bottom has a cleanout fluid hand-hole, overcome the card source problem effectively, make beneficial effects such as the radioactive particle implant surgery is safer, easy, efficient.
