An automated device capable of continuously implanting radioactive particles

Abstract

The invention discloses an automation device capable of implanting radioactive particles continuously. A linear module, a sliding block and a ball screw are connected into a whole. A motor is fixed to the top end of the linear module and connected with the ball screw, a middle adapting piece and the sliding block are fixed, a supporting plate is fixed to the back of the linear module, a quick locking nut is fixed to the top end of the supporting plate, a needle core holding frame is connected with the middle adapting piece together, a needle core is fixed in a clamping groove in the needle core holing frame, a detachable clip supporting frame is fixed to the bottom of the supporting plate, a detachable clip is fixed in the detachable clip supporting frame, a needle core guide pipe is located at the top of the right end of the detachable clip and communicated with a particle channel, the particles are arranged in a particle bin and compressed by a spring connected with a particle compression shaft, a clip cover and the detachable clip are connected together, and a needle sheath positioning piece is fixed to the bottom of the detachable clip. The automation device can achieve fully-automatic implantation of the radioactive particles, is easy to operate and suitable for being connected with puncture needles provided by different manufacturers as well.

Description

technical field [0001] The invention relates to a medical device for implantation of radioactive particles between tumor tissues in the skull base and the deep side of the face, in particular to a device for continuously and automatically implanting radioactive particles. It belongs to the technical field of minimally invasive medical devices. Background technique [0002] Radioactive seed implantation therapy is to implant radioactive particles into the tumor or around the tumor, and use the radiation emitted by the particle source core to kill cancer cells, so as to achieve the purpose of treating and alleviating the disease. It has the advantages of less trauma, less side effects and lower recurrence rate. It has achieved good therapeutic effects in clinical practice, and has gradually been accepted and recognized by doctors and patients, making its clinical application show broad prospects. [0003] The various radioactive seed implantation devices that exist at presen...

AI Technical Summary

Problems solved by technology

[0003] The various radioactive seed implantation devices that exist at present all have the following deficiencies: (1) The repeated use of the clips is easy to cause cross-infection; , and then pull out the push rod. At this time, the blood in the tumor will flow back into the particle magazine and the particle magazine through the puncture needle and coagulation will occur, and the radiotherapy particles will appear "jammed source" and cannot be implanted; (3) Magazine It is cumbersome and the positioning is inaccurate; (4) It is basically operated manually by doctors, because the particles are radioactive, and the operation time is long, which has great side effects on the health of doctors and patients
