An efficient axle-type gun-type radioactive particle implanter and a working method thereof

Abstract

The invention discloses an efficient axle-type gun-type radioactive particulate implanter, including a thimble, a puncture needle, a puncture needle-pushing device, a limiting device, a particulate storage unit, an implant gun body, handles and a scale. An upper end portion of that handle is connected with a lower end surface of the implant gun body, and the handle and the implant gun body form apistol-like structure. A scale is arranged on that outer wall of the gun body of the implant. The right end portion of the thimble is disposed in the left end portion of the implant gun body, and theleft end portion of the thimble extends out of the implant gun body, the puncture needle is disposed in the right end portion of the implant gun body and is connected with a puncture needle pushing device, the limiting device is disposed in the implant gun body, and the particle storage device is fixed on the handle. As that particle are stored in the particle storage device, the particles can becontinuously implanted according to the need, the pistol-type structure is adopt, the palm of the hand is convenient to grasp, and the puncture penetration depth can be set by a scale and a limiting device.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a high-efficiency wheel-axle gun-type radiation particle implanter. The invention also relates to a working method of the high-efficiency wheel-axle gun-type radioactive particle implanter. Background technique [0002] As one of the three conventional means of tumor treatment (surgery, chemotherapy, radiotherapy), radiotherapy plays a very important role in the treatment of malignant tumors and prolonging the life of patients. [0003] Due to the limitations of current diagnostic techniques, early detection and early diagnosis cannot be fully realized. Many patients have already entered the middle and late stages of cancer when they see a doctor, and have lost the opportunity for radical surgery. Therefore, the use of radiotherapy has become one of the essential clinical treatment. Clinically, about 70% of tumor patients need radiotherapy at different stages of their treatment. ...

AI Technical Summary

Problems solved by technology

[0007] 1. It is inconvenient to supplement radioactive sources. Generally, a turntable implanter can only hold 20-40 radioactive sources, and a patient often needs to plant dozens or even hundreds of radioactive sources for one treatment. Reloading radioactive sources is neither convenient nor safe

[0008] 2. The volume of the rotary disk storage implantation chamber is large, and the distribution of human lesions has a certain volume range, so it is often necessary to insert multiple hollow needles at the same time within this range. These hollow needles collide with each other, and the inserted hollow needles may even be touched, resulting in the danger of puncturing vital organs or blood vessels of the human body, so the work of surgical operators is very difficult

[0009] 3. In order to continuously transport the radioactive source, it is necessary to completely pull out the push needle and turn the turntable of the storage implant chamber, which will increase the operating burden of the operator

[0010] 4. The storage and implantation compartment of the turntable implanter is large in size and heavy in weight, and the operation is laborious

[0011] 5. The implantation of radioactive particles needs to be implanted while withdrawing the needle, and the cooperation between the hollow needle and the implanter is a taper fit, which is only connected and fixed by friction force. If the operation is not careful during the needle withdrawal process, it is easy to make the hollow Needle separated from implant
