specific Embodiment approach 2

[0033] According to the device described in the first specific embodiment. Fill the radiation particles 10-11 into the radiation particle groove 10-19, insert the anti-radiation lead plate 10-10 vertically into the lead plate groove 10-15, and align the square feet of the spring bracket I 10-7 and spring bracket II 10-8 with the housing The square hole 10-17 on the top of the 10-1 is pressed vertically downwards. When the top of the housing 10-1 is in contact with the upper end cover 10-2, the rotary handle 10-3 is turned, and the rotary handle 10-3 drives the T-shaped bar 10-4 , the T-shaped rod 10-4 cooperates with the locking slot 10-19 on the top of the housing 10-1 to realize the locking of the upper end cover 10-2 and the compression of the radiation particles 10-11; the clamping block I 10-7 and the clamping block Put II 10-8 into the boss of housing 10-1, insert outer needle 11 through outer needle guide plate 9 and insert into semicircular groove 10-16 of clamping blo...

Abstract

The invention relates to a pneumatic prostate particle implantation mechanism, which is applied to the field of medical treatment and mainly comprises an outer needle cylinder, an inner needle cylinder, a brake cylinder, a displacement sensor, an inner needle, an outer needle, a cylindrical slideway, a brake mechanism, a radioactive particle supply mechanism and a base. The air cylinder is fixed to the air cylinder support, an air cylinder support is connected to the base, the outer needle is connected with the particle supply block, the outer needle air cylinder moves in the axial direction to drive the radioactive particle supply mechanism, the radioactive particle supply mechanism is connected with the outer needle, and therefore axial feeding movement of the outer needle is achieved, the inner needle cylinder is connected with a moving sliding block, and the inner needle cylinder pushes the sliding block, the sliding block drives the inner needle to move axially, the inner needle penetrates through the radioactive particle supply module to enter the outer needle, implantation of radioactive particles is achieved, the brake air cylinder is connected with a brake pad, and the brake air cylinder acts to achieve locking and unlocking of a brake. The pneumatic prostate particle implantation mechanism is simple in structure, high in precision, high in needle inserting speed and small in pollution to an operating room, and transmission media are easy to obtain.

Description

technical field [0001] The invention belongs to the field of prostate radiating particle implantation and puncture operation, and is used for replacing the puncture work performed by doctors in the prostate particle implantation operation. Background technique [0002] Prostate cancer is one of the most important cancers in men in my country. The disease has a very high mortality rate and seriously threatens the health of men. With the development of society and the improvement of people's living standards, the incidence rate has been on the rise in recent years. The main reason is the aging of the population in China and excessive intake of animal protein and fat. Since prostate cancer poses a great threat to the life and health of patients, prostate cancer should be detected and treated early in clinical practice. [0003] The treatment of prostate cancer by radioactive particle implantation is a new technology developed in recent years. Implanting radioactive particle ther...
