Problems solved by technology
However, its implanter also has defects, mainly because its puncture needle is inflexible. If it is necessary to three-dimensionally distribute radiation particles in the tumor tissue, multiple needle punctures are required, which brings trouble to the operation on the one hand, and increases the patient's time on the other hand. pain
There is also the possibility of increased bleeding or leakage complications from puncture

The present invention relates to a kind of medical device and using method for the treatment of human cavity organ tumors, in particular to a flexible metal puncture implanter with built-in radioactive microparticles and a scale for implanting radioactive microparticles through an endoscope and an implantation method. The invention solves the defect of large surgical trauma when implanting radioactive microparticles in the existing radioactive microparticle implanter. The technical solution is: a built-in radioactive particle with scaled bendable metal puncture implanter, including a pusher and a puncture needle tube. There is a needle core in the puncture needle tube. In the puncture needle tube, the puncture needle tube can be inserted through the biopsy channel of the thoracic, laparoscope, or fiberscope. The puncture needle tip has a certain angle. When the puncture needle penetrates a certain distance into the tumor, the arc will advance. The direction of the radiation particle distribution can be adjusted by pushing the needle core at the needle angle, and the radiation particles can be punctured and implanted on the surface of the visible tumor, and the radiation particles can be distributed three-dimensionally. In the present invention, the puncture treatment of radiation particles is mainly carried out through an endoscope.
Description
1. Technical field [0001] The present invention relates to a kind of medical device and using method for the treatment of human cavity organ tumors, in particular to a flexible metal puncture implanter with built-in radioactive microparticles and a scale for implanting radioactive microparticles through an endoscope and an implantation method. 2. Background technology [0002] At present, more than 95% of patients clinically diagnosed with cancer are stage II-III, and half of them are malignant tumors of cavity organs. The total surgical treatment rate is no more than 30%, and the effect of chemotherapy is only about 30%. It brings many side effects and seriously affects the quality of life of patients; the current external radiation therapy and post-loading therapy must be irradiated in short periods due to the high radiation intensity, and the tumor can still be repaired in the interval between two irradiations. The damage continues to grow, which affects the therapeutic e...
