Problems solved by technology

Toxicity and adverse biological effects of contrast agents are caused by the formulation medium (e.g. solvent or carrier) as well as by the contrast agent itself and its constituents (e.g. ions of ionic contrast agents), and possibly by their metabolites, which may There will be a certain certainty, and it is very inconvenient to use. Traditional positioning uses metal brackets or locators made of X-ray-opaque hard materials, which will move during surgery, and the positioning range is too large. It produces a tail shadow, which affects the precise positioning of the operation. When the displacement occurs, it needs to be repositioned. It is inconvenient to use and is not conducive to the rapid and effective operation. Therefore, a new type is needed, which can not only be injected into the human body, but also can be effectively performed. positioning device

Abstract

The invention discloses a positioning technique used under X ray. The positioning technique comprises the steps of S1, weighing a certain amount of iohexol and tromethamine, and grinding iohexol and tromethamine in a grinder into 200-500-mesh powder; S2, placing tromethamine in step 1 into a stirrer, then weighing a certain amount of hydrochloric acid, sodium calcium edentate and iopromide, placing hydrochloric acid, sodium calcium edentate and iopromide into the stirrer, adding a certain amount of methanol solution of 75-85% to the stirrer, starting the stirrer, maintaining temperature at 30-45 DEG C, and conducting stirring for 1-3 h; S3, placing iohexol powder in step 1 in the stirrer in step 2. The positioning technique is used for medical operation or examination and positioning, can well achieve recognition on skin, can achieve development during X-ray fluoroscopy and accurate positioning, and can not cause damage to human body.

Description

technical field [0001] The invention relates to the technical field of X-rays, in particular to a positioning process for X-rays. Background technique [0002] With the development of society, medical technology is also improving day by day. When people perform surgery, they often need to perform imaging, and imaging generally uses contrast agents or locators to determine the surgical location. Chemicals injected (or ingested) into human tissues or organs for imaging observation effects. These articles are denser or lower than the surrounding tissue, creating a contrast that displays images with certain devices. For example, iodine preparations and barium sulfate are commonly used in X-ray observation. Contrast agents are one of the most commonly used drugs in interventional radiology operations, mainly used for the display of blood vessels and body cavities. There are various types of contrast agents, and most of the contrast agents currently used in interventional radiol...
