Radioactivity seed source implantation equipment

Abstract

The invention discloses a radioactive seed implanting gun which comprises a gun body connected with a handle, a seed storehouse, a shield lid and a pusher. A socket of the seed storehouse is arrangedon the middle-upper part of the gun body. The socket of the seed storehouse, of which, the middle part of a back wall is provided with a pore canal, the middle part of a front wall is provided with ahollow graft needle, the upper part of the front wall is provided with a buckle plate of the graft needle, and the bottom part is provided with a groove. An anticoagulant input is arranged on the lower part of the groove and a protuberance with a screw is arranged on the top of the socket of the seed storehouse; the seed storehouse comprises a shell and an upper cover and an ejector pin is arranged in the shell. The ejector pin is movably connected with the upper cover by a spring. A via hole is arranged on the lower part of the shell and a bottom hole is arranged at the bottom of the shell. The invention is simple and can be used conveniently, and avoids the source blockage during implantation of the radioactive seed and cross contamination among patients. The setting of the shield lid reduces the radiation dose of the radioactive seed, thereby reducing the radialization to doctors and relevant medical care personnel.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a medical device for tumor tissue implantation treatment, in particular to a radioactive seed source implanter. Background technique [0002] Interstitial implantation therapy is to implant radioactive seeds into the tumor or around the tumor, and use the rays emitted by the seeds to kill cancer cells, so as to achieve the purpose of treating and alleviating the disease. Interstitial implant therapy has been used in the treatment of various solid tumors, such as prostate cancer, breast cancer, liver cancer, brain tumor and ovarian cancer, and has achieved the same therapeutic effect as surgery and external radiation therapy. Although this tumor treatment technology has been widely used clinically in China and has achieved good therapeutic effects, it has gradually been accepted and recognized by doctors and patients. Chinese patent publication number is that CN1846804A dis...

Problems solved by technology

Chinese patent publication number is that CN1846804A discloses " a kind of internal radiotherapy particle implantation gun ", and when it is applied to clinic, its method of use is simple and convenient, has solved the problem of radioactive particle implantation, but has some deficiencies, as: (1 ) The particle chamber of the internal radiotherapy particle implant gun is reused, and cross-infection occurs easily; (2) The shell of the particle chamber and the storage clip are screwed, and the particle chamber and the chamber seat are also screwed, and the processing technology is complicated. The cost is high; (3) when the radiotherapy particles are implanted into the tumor with a push rod during the operation of implanting the tumor, when the push rod is pulled out of the body, the blood in the tumor will flow back into the particle chamber to cause coagulation, and the subsequent radiotherapy particles There will be a "card source" phenomenon
