Interventional medicine, is based on diagnostic imaging, under the guidance and monitoring of medical imaging equipment, the use of puncture needles, catheters, balloons, stents and other interventional equipment, through the body’s natural orifices or tiny wounds will be specific instruments into the body lesions for diagnosis or minimally invasive treatment, which can reverse the dilemma of the internal medicine drugs on the change of the tissue structure can not do anything about it, but also avoid the surgical operation on the organism Surgery on the body can be avoided “drastic” injury. It can avoid the “drastic” damage to the body caused by surgery. It causes little damage to the human body, but the therapeutic effect it can exert is very reliable, therefore, interventional medicine has become the third major clinical discipline after internal medicine and surgery.
Digital subtraction angiography (DSA), generally consists of X-ray generator, digital imaging system, mechanical system, computer control system, image processing system and auxiliary system, etc. DSA is an angiographic method of computer-assisted imaging. It is the application of computer programs for the completion of two imaging in the injection of contrast agent before the first imaging, and the computer will be converted to digital signals stored in the image, injected into the contrast agent again after the imaging and converted to digital signals, the two digital subtraction, eliminate the same signals, to get a only the contrast agent of the blood vessel image, this image is more than the conventional angiography used in the past, the image displayed by the angiographic contrast medium This image is much clearer and more intuitive than the conventional angiography used in the past, and some of the finer vascular structures can also be shown.
Simply put, a contrast agent is injected into the blood vessel to be examined to reveal the original shape of the blood vessel. Then through the system processing, the blood vessels are displayed more clearly, which is convenient for doctors to diagnose or carry out surgery, and this is why DSA is called “vascular machine”.DSA has a wide range of clinical use, applicable to the heart, brain, peripheral and various parts of the vasculature, tumors, urology, respiratory tract, and other gastrointestinal tract and other departments including clinical diagnosis and minimally invasive interventional therapy. It is suitable for clinical diagnosis and minimally invasive interventional therapy.
Dynamic flat C-arm compared to the general small C-arm, not only is the balloon power increased, dynamic flat C-arm product design systematic and maneuverability is to carry out complex interventional procedures is a strong guarantee, increased DSA-related functions. For example, the PLX7100A can be used in orthopedics, hepatobiliary and pancreatic surgery, gastroenterology, in addition to cardiac and cerebral interventions, non-vascular parts of the perfusion embolization, balloon angioplasty, stenting, a variety of parts of the puncture, biopsy, drainage and so on, for example, percutaneous percutaneous biliary drainage, peritoneal drainage, fluoroscopic foreign body removal, biliary stent implantation, digestive stent implantation, and so on. implantation of biliary stenting, gastrointestinal stenting, etc.
The C-arm in a dynamic flatbed has its own unique advantages over the high running costs of DSA for interventional clinical use. It is more flexible and can be used in digestive, oncology, gynecology, urology, peripheral and other specialties. Hospitals do not need to do power electric transformation, general laminar flow operating room environmental conditions can meet the installation and use of the requirements. Moreover, with the rapid popularization of interventional technology and the promotion of the national hierarchical diagnosis and treatment system, the C-arm in the dynamic plate has the advantages of appropriate power, high cost-effectiveness, and reduction of the operator’s radiation exposure. As a green and safe interventional diagnostic and therapeutic equipment, it can be said to be the ideal choice of interventional equipment for primary general hospitals.
