The invention discloses a particle implantation device with double implantation bins, and belongs to the technical field of medical instruments. A sliding bin base is installed in a shell in a sliding mode, bin changing push rods are arranged on the two sides of the sliding bin base respectively, through holes are correspondingly formed in the two sides of the shell, and the bin changing push rods penetrate through the through holes; a first bin position and a second bin position are arranged on the sliding bin base, the first bin position is connected with a radioactive particle implantation bin, and the second bin position is connected with a supporting particle implantation bin; an upper connector assembly is connected with the upper plane of the shell, a lower connector assembly is connected with the lower plane of the shell, and the lower connector assembly is used for being connected with an implantation needle; an upper through hole and a lower through hole are formed in the upper plane and the lower plane of the shell respectively; and when the sliding bin base slides to different gears, the upper connector assembly, the upper through hole, the lower through hole and the lower connector assembly can form a through channel with the first bin position or the second bin position respectively. According to the particle implantation device, radioactive particles and supporting particles can be conveniently and rapidly placed into the implantation needle alternately, and the distance between every two adjacent radioactive particles is accurately controlled.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a particle implantation device with double implant chambers. Background technique [0002] Radioactive particle implantation technology has been widely used in the treatment of malignant solid tumors. The implementation of this technology mainly depends on the particle implantation device, that is, the particle implantation gun. At present, the particle implantation guns developed at home and abroad are single-chamber. Such as the domestic invention patent: the publication number is a kind of radioactive particle implantation gun of CN105413049A, and the foreign particle implantation gun is such as the Mick200 implantation gun. When implanting the particles, the above-mentioned device distributes the particles intermittently by withdrawing the needles. Due to the influence of the accuracy of the needle withdrawal distance of the operator and the displacement o...
