Abstract

The invention provides a particle implanting device. The particle implanting device comprises a particle cabin base and a push needle component; the front end of the particle cabin base is connected with a puncture needle, and the rear end is connected with the push needle component; the push needle component comprises a push needle, a driving slider, and at least two sliding rods; two driving ends of the driving slider are connected with the two sliding rods, and slide along an axial direction of the two sliding rods; one end of the sliding rod is connected with the rear end of the particle cabin base; one end of the push needle is connected with the driving slider, and the other end is inserted in a particle channel of the particle cabin base; the sliding rods are provided with multiplelimiting stop pins; the driving slider is stopped and limited by the limiting stop pins. Different sliding distances of the driving slider are set corresponding to a preset length of the puncture needle; the multiple limiting stop pins are capable of enabling one push needle to be suitable for the different lengths of the puncture needles, and the push needle does not need to be replaced repeatedly, so one particle implanting device can be suitable for the different lengths of the puncture needles.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a particle implanter. Background technique [0002] At present, radioactive substances are widely used in various fields such as production, scientific research, medical treatment, biology, and laboratories, especially as medicines, and have been widely used in clinical applications at home and abroad. Radioactive seed implantation is a minimally invasive treatment method for malignant tumors, and it is a type of brachytherapy. It has the advantages of simple operation and good therapeutic effect, and its clinical application has broad prospects. [0003] Radioactive substances are implanted into the human body through a seed implanter. The front end of the particle implanter is connected with a puncture needle, and the rear end is connected with a push needle. The puncture needle is inserted into the lesion of the patient, and the particles in the particle implanter are pus...
