C-arm X-ray machine

Abstract

The invention relates to a C-arm X-ray machine. The C-arm X-ray machine comprises a main frame and a C-type rack, the main frame and the C-type rack are mutually connected through a shaft body, the C-type rack can rotate relative to the main frame, the C-type rack comprises an arm body, an X-ray generating end and an X-ray receiving end, the X-ray generating end is provided with an X-ray generator and a first metal protective cover, the X-ray receiving end is provided with an X-ray image intensifier and a second metal protective cover, the arm body is provided with a metal protective sleeve, the X-ray generator is located in the first metal protective cover and is tightly fitted with the first metal protective cover, the X-ray image intensifier is located in the second metal protective cover and is tightly fitted with the second metal protective cover, and the first metal protective cover faces to an X-ray emission hole in one surface of the X-ray receiving end. The C-arm X-ray machine is reasonable in structural design, effectively stops diffusion of ionizing radiation of an X-ray, reduces scattered rays produced by irradiation of the X-ray on a boundary region of an object, and reduces damages to a human body.

Description

Technical field [0001] The invention relates to the field of medical equipment and equipment, in particular to 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 X-ray machine. Among them, the movable C-arm is often used to equip X-ray imaging equipment in surgical positioning, such as orthopedic internal fixation. , Limb fractures, spine fractures, etc., thrombolysis, stent implantation, interventional surgery, etc., can also be used to find the location of metal foreign bodies in the body or foreign bodies such as instrument dressing gauze. Compared with the ordinary X-ray machine, the C-arm X-ray machine has more stable performance and lower diagnosis cost, which is a powerful guarantee for carrying out complex interventional surgery. [0003] The X-ray machine will produce a large amount of ionizing radiation which is extremely harmful to the human body during u...

AI Technical Summary

Problems solved by technology

The current ionization protection measures are mainly achieved by improving the external environment, such as improving the operating skills of medical staff to minimize the number of exposures and exposure time, choosing a larger operating room to place machines, installing protective layers on walls and doors, and washing hands before operations Wear protective items such as lead caps, lead collars, and wrapped lead clothing beforehand to reduce the radiation dose as much as possible. The items in the operating room should be neatly arranged without placing too many items, and the distance from the X-ray source should be increased. Or in direct-vision surgery, under the condition of ensuring sterility and sufficient exposure of the surgical field, protective equipment is used to cover the patient and take pictures of unrelated parts, etc., but there is little improvement in the structure of the X-ray emitting device source itself
