Seed implantation device with magazine capable of being automatically replaced and implantation method with seed implantation device with magazine capable of being automatically replaced applied

Abstract

The invention relates to a seed implantation device with a magazine capable of being automatically replaced and an implantation method with the seed implantation device with the magazine capable of being automatically replaced applied, and belongs to the field of medical instruments. The seed implantation device with the magazine capable of being automatically replaced is composed of a fixing base, a magazine turntable, a seed magazine, a sleeve needle, a seed pushing needle, a driving motor, a left-hand Mecanum wheel and a right-hand Mecanum wheel; the fixing base is provided with a turntableguiding column, a magazine installation notch, a pushing needle channel and a sleeve needle connection base; and the magazine turntable is provided with a turntable sleeve and a magazine fixing clamping jaw. The implantation method with the seed implantation device applied is further provided. According to the seed implantation device with the magazine capable of being automatically replaced andthe implantation method with the seed implantation device with the magazine capable of being automatically replaced applied, in the premise of the standard safe magazine, the maximum seed bearing capacity of the implantation device is improved, and the seed magazine can be automatically switched in a puncture state in an operation, so that the problem of implantation operation breaks due to the fact that medical workers frequently communicate to replace a magazine in an operation is solved; and through cooperation of one set of Mecanum wheels and the turntable guiding column, rotation and lifting motions of the seed turntable is achieved, the structure is simple, driving is flexible, and the stationarity of seed implantation is effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a particle implanter capable of automatically replacing a magazine and an implantation method using the same. Background technique [0002] Radioactive seed implantation surgery is to implant radioactive particles such as iodine 125 into the patient's tumor area through a puncture channel, and use the sensitivity of diseased tissue to radiation to eliminate cancer cells and perform radiotherapy. As a treatment method of radiotherapy internal irradiation, it has been widely used in the treatment of prostate cancer, lung cancer, liver cancer and many other cancers, with good therapeutic effect and prognosis quality. [0003] In clinical practice, a single seed implantation operation generally needs to implant more than dozens of radioactive seeds, but the standard magazine capacity of the current seed implanter is 10, so the surgeon and the equipment nurse need to communica...

AI Technical Summary

Problems solved by technology

However, there is still the problem that the magazine needs to be replaced manually after it is exhausted. The proposed large-capacity magazine, which is nearly 10 times the capacity of the currently used particle magazine in clinical practice, is difficult to implement in terms of clinical requirements and radiation safety. There is a phenomenon of blood flowing back through the puncture needle, and if the particle magazine is not replaced for a long time, it is easy to cause radioactive particles to get stuck due to blood coagulation and cannot be implanted, resulting in a more serious problem of interruption of intraoperative implantation
