Embodiment 1

[0032] ㅤㅤ A device that continuously implants radioactive seeds such as Figure 1~4 Shown includes a rack 1, which is set on the rack 1 for loading radioactive particles 4 and a particle loading module 2 for realizing continuous implantation of multiple particles in a single push, and for driving the push pin to move axially, together with the particle loading module 2 Cooperate with the push pin driving mechanism 3 to realize particle pushing and implantation. The particle loading module 2 includes a magazine fixing module 21 connected to the frame 1 , a continuously implantable particle magazine 22 matched with the magazine fixing module 21 , and a planting puncture needle connected to the magazine fixing module 21 . The continuously implantable particle magazine 22 includes a magazine housing 221 , a particle loading cavity 222 matched with the magazine fixing module 21 , and a particle ballast rod 223 matched with the particle loading cavity 222 . The push pin drive mecha...

Embodiment 2

[0036] ㅤㅤ According to Embodiment 1, this embodiment provides a method for continuous implantation of radioactive particles using the above-mentioned continuously implantable radioactive particle device, which specifically includes the following steps.

[0037] a. First, retreat the implant push pin 34 to leave all the placement areas of the continuously implantable particle magazines 22 to prepare for the placement of the continuously implantable particle magazines 22 and avoid interference.

[0038] b. Insert the continuously implantable particle magazine 22 loaded with several radioactive particles 4 into the magazine fixing module 21. The number of radioactive particles 4 is determined by the medical institution according to the number of implanted particles required for the operation.

[0039] c. Move the implant push needle 34 along the puncture direction until the needle tip of the implant push needle 34 coincides with the needle tip of the disposable cannula puncture ne...

Embodiment 3

[0045] ㅤㅤ This embodiment is basically the same as Embodiment 2, the difference is that according to clinical needs, for example, in the implantation of radioactive seeds in the prostate, it is sometimes necessary to implant multiple radioactive particles at different positions sequentially in the same puncture channel, specifically After step a, step b, step c, step d and step e are completed in sequence, the implant push needle 34 passes through the particle loading cavity 222 in sequence, and simultaneously pushes a plurality of radioactive particles 4 for use in the puncture channel The first radioactive particle 4 is moved out of the front end of the disposable cannula puncture needle 23 to complete the implantation of the first radioactive particle, and then the radioactive particle implantation mechanism is moved back to place the disposable cannula puncture needle 23 The needle tip retreats to the implantation position of the next radioactive seed in the same puncture c...

Abstract

The invention relates to a device capable of continuously implanting radioactive particles and an implanting method using the device, and belongs to the field of medical instruments. The device is composed of a rack, a particle loading module and a push pin driving mechanism. The particle loading module is arranged on the rack and is used for loading the radioactive particles and realizing continuous implantation of the multiple particles by one time of pushing; and the push pin driving mechanism is arranged on the rack, is used for driving a push pin to move axially, and is matched with the particle loading module to realize particle push and implantation; and meanwhile, the invention provides an implantation method using the particle implantation device. The invention provides a continuously implantable particle magazine, and the continuously implantable particle magazines are sequentially arranged along the axis direction of a pin body, so that the requirement of simultaneously implanting the multiple particles in a radioactive particle implantation operation process is met, and the problem that the particle magazine needs to be replaced for multiple times in the current operation is solved. The quality efficiency and precision of the radioactive particle implantation operation are improved, and the labor intensity of medical staffs is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device capable of continuously implanting radioactive particles and an implanting 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. The current clinical implantation method is mainly to manually implant radioactive particles sequentially through a puncture needle or a radioactive seed implanter. [0003] Taking the prostate seed implantation surgery as an example, a single operation generally needs to implant 100-120 radioactive seeds, but the standard magazine capacity of the current particle implanter is 10, so the particle bombs need to be replaced frequently during the operation In addition, in a single punc...
