Description

Technical Field

[0001] The invention relates to the field of puncture positioning, and more specifically to a cardiology puncture positioning device. Background Art

[0002] Cardiology, also known as cardiovascular medicine, is a clinical department set up by the general internal medicine department of hospitals at all levels for the diagnosis and treatment of cardiovascular and vascular diseases. The diseases treated include angina pectoris, hypertension, sudden death, arrhythmia, heart failure, premature beats, arrhythmia, myocardial infarction, cardiomyopathy, myocarditis, acute myocardial infarction and other cardiovascular diseases. At present, clinically, puncture needles are mainly used for pleural effusion puncture in cardiology patients. The nature of pericardial effusion can be understood by testing the fluid in the pericardial cavity, and the cause of pericarditis can be identified based on the nature of the pericardial effusion. In addition, when there is a large amount of pericardial effusion, the patient's blood circulation is seriously disturbed, venous blood cannot return to the heart smoothly, and the heart's blood discharge function is impaired. The patient's symptoms can be alleviated or even eliminated by releasing a large amount of effusion through pericardial puncture.

[0003] In order to improve the accuracy when using the existing puncture device, the puncture device is generally positioned in conjunction with a positioning device.
