Full-automatic needle and bomb replacement particle implantation device

Abstract

In order to solve the problems that when a radioactive particle implantation operation is carried out, a large number of radioactive particles need to be implanted in each operation, due to the fact that an implanted puncture needle can enter tumor cells to carry out particle implantation, an outer needle needs to be replaced when the particles are implanted in a channel changing mode, and the workload of the operation can be greatly increased due to manual replacement, the invention discloses a full-automatic needle and bomb replacement particle implantation device, which mainly comprises anautomatic bullet replacement module, a transmission slideway mechanism, a needle replacement turntable module and an internal driving module, the particle implantation needle is mounted on the automatic bullet replacement module and performs a particle implantation process through the transmission slideway mechanism; according to the invention, the time of auxiliary operations such as needle replacement, bullet replacement and the like except the operation process of a doctor can be reduced, the efficiency is improved, and the doctor can focus on the operation more intensively, so that the accuracy of particle implantation is improved, the treatment time is shortened, and the whole operation process is simpler, more accurate and more reasonable.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a fully automatic needle-changing and bomb-changing radioactive particle implantation device. Background technique [0002] Radioactive seed implantation therapy mainly relies on a stereotaxic system to accurately implant radioactive seeds into the tumor body, and emits continuous, short-distance radiation through a miniature radioactive source, so that the tumor tissue is destroyed to the maximum extent, while the normal tissue is not damaged or only slightly damaged. This technology has the characteristics of strong targeting, less trauma, quick curative effect and less side effects. [0003] Radioactive substances are implanted into the human body through the particle implantation device. The front end of the particle implantation device is equipped with a puncture needle, and the rear end has a push needle for particle implantation. The particle implantation device has a partic...
