C type arm of C-arm X-ray machine

Abstract

The invention relates to a C type arm of a C-arm X-ray machine. The C-arm X-ray machine comprises a main frame and the C type arm which are connected with each other through a shaft, wherein the C type arm can make rotary motion relative to the main frame through the shaft, the C type arm comprises an arm body, a drive device, a digital display device, a single chip microcomputer, a synchronous pulley and a rotary encoder, the drive device comprises a stepping motor for providing electricity and a meshing gear for transmitting power, the single chip microcomputer is connected with the digital display device, the stepping motor and the rotary encoder respectively, the stepping motor, the synchronous pulley and the arm body are connected in sequence, the rotary encoder is arranged on the arm body, and the rotary encoder and the arm body are in gear drive. The C type arm has the beneficial effects that the rotation angle of the C type arm can be accurately controlled, the noise is small, the structure is simple, the use is convenient, and the performance is stable.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a C-arm of a C-arm X-ray machine. Background technique [0002] The generation of X-rays is a series of complex physical processes, and the device that generates X-rays is called an X-ray machine, in which the movable C-arm is often used to equip X-ray imaging equipment in surgical positioning, such as orthopedic internal fixation surgery , Limb fractures, spinal fractures, etc., thrombolysis, stent implantation, interventional surgery, etc., can also be used to find metal foreign bodies in the body or locate foreign bodies such as instrument dressings and gauze left in the body. Compared with ordinary X-ray machines, C-arm X-ray machines have more stable performance and lower diagnostic costs, which are a strong guarantee for complex interventional operations. [0003] The C-arm is an important structure of the C-arm X-ray machine. The emitting tube and the X-ray receiving devi...

AI Technical Summary

Problems solved by technology

The C-arm usually rotates around the support shaft on the main machine through the bearing, and then locks it through the brake mechanism after turning to the required position. Due to the heavy weight of the C-arm part, it is difficult to control the position when rotating around the support shaft, which may easily cause rotation. Excessive or insufficient rotation will bring inconvenience to the diagnosis and treatment process
