Problems solved by technology

During cardiovascular angiography, the risk of poisoning is several times higher with rapid injection than with slow injection, mainly due to the hyperosmotic effect of the contrast medium. Due to the viscosity of the contrast medium, at present, the push of the contrast medium injected by the existing equipment is not easy to control Injection speed

Abstract

The invention discloses a cardiac imaging assisted surgical instrument and belongs to the technical field of medical instruments. The technical scheme includes that the cardiac imaging assisted surgical instrument comprises a body, a moving base is arranged on the lower side of the body, moving legs are arranged on the lower side of the moving base, a moving wheel is arranged on the lower side of each moving leg, the moving wheel is assembled with the moving leg through a steering shaft, and a moving brake is arranged on the upper side of each moving wheel. By the arrangement, medical personnel can well control speed and injection volume of injection of a contract agent when cardiac angiography surgery is performed on cardiovascular patients, patients' suffering is alleviated, working efficiency of the medical personnel is improved, and medical risk is lowered.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, in particular to a cardiac contrast imaging auxiliary operation device. Background technique [0002] Cardiac angiography is a common medical examination method. It injects a contrast agent into certain parts of the heart and great vessels through a cardiac catheter to visualize the heart and take a quick film to show the pathological changes of the anatomical structure of the heart and great vessels and the circulation function. Happening. Cardiac angiography is one of the important inspection methods before cardiac surgery, and most complicated heart diseases must be checked. Cardiac angiography includes coronary angiography and heart (atrium, ventricle) angiography. Coronary angiography is to use a hair-thin catheter along the artificial entrance of the radial artery (wrist) or femoral artery (thigh) to the coronary artery opening of the heart, and then inject contrast agent (un...
