Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] Take prostate cancer seed implantation surgery as an example, such as Figure 1-4 The shown radioactive particle chain implantation device includes a support base 1 made of stainless steel. The support base 1 is connected with a rotating assembly that rotates around the Z axis, and the rotating assembly is fixedly connected with a bracket extending along the Z axis. 2. The bracket 2 is movably connected with a horizontal frame assembly that can move up and down along the bracket, and the horizontal frame assembly is movably connected with a particle needle assembly that can move left and right along the horizontal frame assembly;

[0019] The particle needle assembly includes a stainless steel lateral moving part 3 that is movably connected to the horizontal frame assembly. The lower end of the lateral moving part 3 is fixedly connected with a vertical...

Abstract

The invention belongs to the technical field of medical apparatuses and instruments, relates to a tumor treatment appliance and in particular relates to a radioactive particle chain implantation device. The radioactive particle chain implantation device mainly comprises a supporting base, wherein a rotating assembly capable of rotating around an axis Z is connected onto the supporting base; a bracket capable of extending along the axis Z is fixedly connected onto the rotating assembly; a cross frame assembly capable of moving up and down along the bracket is movably connected onto the bracket;and a particle needle assembly capable of moving from side to side along the cross frame assembly is movably connected onto the cross frame assembly. Radioactive particle chains are implanted into tumors at a time. The radioactive particle chain implantation device disclosed by the invention is accurate in positioning and convenient to operate, and the manual operation error of an operator is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a tumor treatment device, in particular to a radioactive particle chain implantation device. Background technique [0002] The full name of particle implantation is "radioactive particle interstitial implantation brachytherapy", which is a method of implanting iodine 125 particle radioactive source into the tumor, releasing γ-rays, damaging the DNA of tumor cells, and finally inducing tumor cell necrosis and apoptosis. means. Particle implantation therapy involves the implantation of radioactive sources, the core of which is the arrangement of radioactive particles. Now in clinical use is a radioactive isotope called iodine-125. Each iodine-125 particle is a small radiation source, and the rays near the center are the strongest, which can minimize the damage to surrounding normal tissues. [0003] In order to achieve the therapeutic effect, a certain number of radioactiv...
