Problems solved by technology

[0002] Clinically, it is found that the afterloading treatment machine has the following problems in the use process: (1) The diameter of the driving wheel of the radiation source and the simulation source is easy to change. treatment effect
(2) The driving wheels of the radiation source and the simulation source are flat wheels, and the contact area is small, so the clamping source line is easy to slip, which will also lead to inaccurate wire feeding length
(3) The integrity of the radioactive source cannot be judged directly in the center of the storage tank, which may cause accidental injury to medical staff

Abstract

The source wire driving system of post therapeutic apparatus includes driving wheels, a wire storing pipe and a source storing tank. It features the driving wheels, which include one driving wheel and one driven wheel with V-shaped grooves in the addendums and axial shifter in the driven wheel; and the wire storing pipe, which is provided with intermittently set slots and photoelectronic displacement sensors comprising emitting end and receiving end inside the slots. The source wire driving system of post therapeutic apparatus has accurate source output, stable performance and high safety and reliability to ensure high treating effect of the post therapeutic apparatus.

Description

technical field [0001] The invention relates to an improved source line driving system of an afterloading treatment machine, which is used for the source line driving of afterloading treatment machine medical equipment. Background technique [0002] Clinically, it is found that the afterloading treatment machine has the following problems in the use process: (1) The diameter of the driving wheel of the radiation source and the simulation source is easy to change. treatment effect. (2) The driving wheels of the radiation source and the simulation source are flat wheels, and the contact area is small, so the clamping source line is easy to slip, which will also lead to inaccurate wire feeding length. (3) The integrity of the radioactive source cannot be judged directly in the center of the source tank, which may easily cause accidental injury to medical staff. Contents of the invention [0003] The purpose of the present invention is to provide an improved source line driv...
