Problems solved by technology

[0006] However, behind the rapid development of radioactive seed implantation and interventional radiotherapy technology, there is an important problem
With the explosive increase in the number of operations and the amount of radioactive particles used, doctors are now manually loading radioactive particles into the particle clips used for interventional puncture during radioactive seed implantation and interventional radiotherapy, which exposes doctors to radiation hazards for a long time , and the efficiency of filling particles by hand is very low, which increases the operation time and the workload of doctors

Embodiment example 1

[0055] This implementation case selection 125 I Radioactive particles and the particle clips that match it are sorted and loaded. Using the method of gas-driven particles, the inert gas meeting the medical standard of 0.5MPa will 125 Particles are blown up and move along the multi-section arc plates and guide blocks, and then they are arranged in an orderly manner along the axial direction and enter the particle conveying channel.

[0056] When entering the particle transport channel 125 After the number of particles exceeds the number of particles required in the particle magazine, the particle locking device is activated to locate the particles behind the first particle, and the traction device moves the first particle to the particle outlet and enters the particle delivery channel.

[0057] first 125 After the I particle enters the particle channel, close the particle outlet, and start the push rod to push the particle into the particle magazine along a straight line per...

Embodiment example 2

[0060] This implementation case selection 60 Co particles and corresponding particle magazines are sorted and loaded. By means of high-frequency vibration, the 160 The Co particles are aligned and enter the particle delivery channel.

[0061] In this embodiment, the particle delivery channel is divided into two, that is, two columns of particles are connected in parallel. During the filling process, two particles enter the particle channel at the same time and keep the axis parallel. Under the action of the push rod, the two particles move side by side along the arc-shaped particle channel and then enter the particle magazine. After a few cycles the particles in the particle magazine 125 The number of I particles was as expected. Finally, the magazine is ejected automatically.

Description

technical field [0001] The invention belongs to the field of interventional radiotherapy in the medical field. Specifically, the invention relates to an automatic sorting and filling device for radioactive particles, which replaces the manual loading of radioactive particles in current interventional radiotherapy operations with automatic equipment. Background technique [0002] Malignant tumor is a public health problem that seriously threatens the quality of human life and life. In the United States alone, more than 1.7 million new malignant tumors are diagnosed each year, and the death toll is about 610,000. The situation in China is even more serious. According to the report of the National Cancer Center, cancer patients in China account for nearly 40% of the total number of cancer patients in the world. About 10,000 people are diagnosed with malignant tumors every day, and an average of 7 people suffer from cancer every minute. Due to the wide variation in cancer spectr...
