Problems solved by technology

[0002] At present, in my country, the internal radiotherapy technology of implanting radioactive particles into the human body to treat tumors has been widely used in clinical practice, but most of the implanted devices have to be imported, and these devices are expensive. For this reason, some people in China have been developing such devices, such as The "Visible Implantation Gun for Treating Tumors with Seed Source Interstitial Implantation" disclosed in my country's utility model patent, the announcement number CN2524773Y,

Abstract

The radiotherapeutic particle implanting gun is used for implanting radiotherapeutic particle into body of cancer patient. It includes a gun body, a handle, a particle gun capable of being inserted into the gun body, an implanting needle and a push rod. The gun body consists of a particle bin seat, a front cover plate, a back cover plate, an implanting needle pinch plate, and a push rod guiding tube. The implanting needle has a central hole and a conic tail hole, and is fitted to the push rod guiding tube. The particle bin includes a casing, a spring and a mandril inside the casing, and a particle storing holder screwed to the casing. The mandril under the action of the spring may be pushed to the bottom of the particle storing holder and the push rod may be pushed to implant the particle into the disease focus of the patient. The radiotherapeutic particle implanting gun may be used to implant over hundred particles.

Description

technical field [0001] The invention relates to the technical field of medical equipment for implanting materials into the human body, in particular to the medical equipment for implanting radioactive particles into the human body. Background technique [0002] At present, in my country, the internal radiotherapy technology of implanting radioactive particles into the human body to treat tumors has been widely used in clinical practice, but most of the implanted devices have to be imported, and these devices are expensive. For this reason, some people in China have been developing such devices, such as The "Visible Implantation Gun for Treating Tumors with Seed Source Interstitial Implantation" disclosed in my country's utility model patent, the announcement number CN2524773Y, is a better substitute. Shield the cover plate, turn the source storage turntable so that the number on the shield cover is aligned with the number on the source storage turntable, and use the source sup...
