Abstract

The invention discloses a device for implanting radioactive particles, which includes a fixed base, a motor, a transmission assembly, a needle core fixing piece and an implant gun clamp. The fixed base has opposite first ends and second ends, and the motor is fixedly mounted on the fixed base. The first end of the first end; the transmission assembly includes a screw and a moving block threaded with the screw, the screw is rotatably arranged on the fixed seat, and one end of the screw is fixedly connected to the output shaft of the motor; the needle core fixing part is fixedly connected to the moving block, The implant gun clamp is arranged on the second end of the fixed base and is opposite to the needle core holder, so that the needle core on the needle core holder is suitable for moving in the implant gun on the implant gun clamp and implanted into the patient's body radioactive particles. The radioactive particle implantation device of the present invention can continuously implant particles, has high working efficiency, and is simple and convenient to operate. At the same time, the needle core is pushed in and pulled out at the same speed each time, which can avoid problems such as particle jam and implantation failure.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for implanting radioactive particles. 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 outer puncture needle is inserted into the tumor site of the patient, and the head of the outer puncture needle is connected to the outer puncture needle interface of the implant 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 radioac...
