Abstract

The invention relates to a radioactive particle implanting gun, which comprises a gun body, wherein the gun body is arranged on a handle; the front end of the gun body is provided with an adapter assembly; the back end of the gun body is provided with a push pin assembly; a cavity used for fixing a cartridge holder assembly is arranged in the gun body; and two holes penetrating through the gun body are formed in one side wall of the gun body, wherein a positioning pin is arranged in the hole near the top of the gun body; and a positioning pin cover is arranged in the hole near the bottom of the gun body. The radioactive particle implanting gun has the excellent effects that the adapter assembly, the gun body and the push pin assembly are designed into a whole; the problem that in the prior art, once alignment is needed when the push pin is pushed once, and then the insertion and the pulling out can be completed is solved; an operator can conveniently concentrate; meanwhile, the instrument compatibility is improved; all parts of the implanting gun are mutually independent; when the parts are damaged, only the damaged parts need to be replaced; the problem that the whole set of implanting equipment is scrapped in the prior art is solved; the structure is simple; the operation is convenient; and portability is realized.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a radioactive particle implantation gun. Background technique [0002] Radioactive seed implantation therapy is a treatment method that implants a radioactive source inside the tumor and allows it to continuously release radiation to destroy the tumor. , Short-distance radiation, so that the tumor tissue suffers maximum damage, while normal tissue is not damaged or only slightly damaged. [0003] At present, the implantation of radioactive particles is done manually. Specifically, the implantation needle is inserted into the tumor site of the patient, and the head of the implantation needle is connected to the implantation needle interface of the implantation gun. The frontmost particles in the particle magazine are located in the trajectory of the implant gun, and the medical staff manually pushes and pulls the needle core along the trajectory to push the radioactiv...
